Description

包含二氧化氯的细胞凋亡诱导剂及其在制备化妆品或抗衰老或抗肿瘤药物中的用途Apoptosis inducing agent comprising chlorine dioxide and use thereof in preparing cosmetic or anti-aging or anti-tumor drugs 技术领域Technical field
本发明属于抗衰老和肿瘤治疗领域,具体涉及通过诱导衰老细胞和肿瘤细胞发生凋亡,从而抗衰老和治疗肿瘤的方法,以及二氧化氯在制备用于哺乳动物细胞凋亡诱导剂的化妆品或药物的应用。The invention belongs to the field of anti-aging and tumor treatment, and particularly relates to a method for preventing apoptosis and senescence and treating tumor by inducing apoptosis of senescent cells and tumor cells, and chlorine dioxide for preparing cosmetics for mammalian apoptosis inducer or The application of drugs.
背景技术Background technique
机体的衰老不能等同于细胞的衰老,但是前者是后者累计的结果,因此机体衰老一定程度上可以用衰老细胞的百分比来刻画。机体内总有细胞在不断地衰老与死亡,同时又有细胞增殖产生新生细胞进行补偿。如果细胞增殖产生的新生细胞不仅全部补充死亡的细胞,而且能够将部分的衰老细胞替换,那么机体就表现的更为年轻。有研究表明:终身清除衰老细胞,能够延迟与年龄相关的表现型的最初出现时间。而且,晚年的清除会延缓已经出现的与年龄相关的病症的发展。这表明,衰老细胞的确能引起与年龄相关的表现型,而且它们的清除能够防止或延迟与年龄相关的组织功能丧失(Baker DJ,et al.Clearance of p16Ink4a-positive senescent cells delays ageing-associated disorders.Nature,2011,479:232-236)。可以说,清除衰老细胞,降低衰老细胞的比例,机体就能表现的更为年轻,并且可以防止或者延迟与年龄相关的组织功能丧失。衰老细胞的死亡实质上就是细胞凋亡。(惠宏襄等,《自由基与细胞凋亡》,《生物化学与生物物理进展》,1996;23:12)。The aging of the body can not be equated with the aging of the cells, but the former is the cumulative result of the latter, so the body aging can be characterized to a certain extent by the percentage of senescent cells. There are always cells in the body that are constantly aging and dying, and at the same time, cells proliferate to produce new cells to compensate. If the nascent cells produced by cell proliferation not only fully replenish dead cells, but also replace some of the senescent cells, the body will behave younger. Studies have shown that lifetime aging of senescent cells can delay the initial appearance of age-related phenotypes. Moreover, the elimination of later years will delay the development of age-related conditions that have already occurred. This suggests that senescent cells do cause age-related phenotypes, and that their clearance prevents or delays age-related loss of tissue function (Baker DJ, et al. Clearance of p16Ink4a-positive senescent cells delays ageing-associated disorders. Nature, 2011, 479: 232-236). It can be said that by eliminating aging cells and reducing the proportion of aging cells, the body can be younger and can prevent or delay the loss of age-related tissue function. The death of aging cells is essentially apoptosis. (Hui Hongwei et al., "Free Radicals and Apoptosis", Progress in Biochemistry and Biophysics, 1996; 23:12).
衰老并不意味着濒临死亡,如果定期更换培养液,衰老细胞仍可长期生存(Seshadri T,Campisi J.Repression of c-fos transcription and an altered genetic program in senescent human fibroblasts.Science,1990 Jan 12;247(4939):205-9)。但衰老细胞的增殖抑制是不可逆的,其生长停滞在细胞周期G1期,不能再进入S期。这提示衰老细胞可能比增殖活跃的年轻细胞抗凋亡,从而长期维持生存(黄英、张宗玉童坦君,《人衰老成纤维细胞凋亡的可诱导性》,《中华老年医学杂志》,2000年6月第19卷第3期)。Aging does not mean dying. If the culture medium is changed regularly, aging cells can survive for a long time (Seshadri T, Campisi J. Repression of c-fos transcription and an altered genetic program in senescent human fibroblasts. Science, 1990 Jan 12;247 (4939): 205-9). However, the inhibition of proliferation of senescent cells is irreversible, and its growth is arrested in the G1 phase of the cell cycle, and can no longer enter the S phase. This suggests that senescent cells may be anti-apoptotic compared to proliferating young cells, thus maintaining long-term survival (Huang Ying, Zhang Zongyu, Tong Tanjun, "Inducible Apoptosis of Human Aging Fibroblasts", Chinese Journal of Geriatrics, 2000 June, Vol. 19, No. 3).
因此在理论上找到了一种抗衰老的思路,即通过对衰老细胞的凋亡诱导,促使衰老细胞发生凋亡,走向死亡,从而得以从机体上清除出去。机体会自动启动干细胞再生能力,再生出新的细胞以代替被清除的细胞,使该机体年轻化。 Therefore, in theory, an anti-aging idea was found, that is, through the induction of apoptosis of senescent cells, the senescent cells are caused to undergo apoptosis and go to death, so that they can be removed from the body. The body will automatically initiate stem cell regeneration, regenerate new cells to replace the cleared cells, and make the body younger.
有意识的诱导衰老细胞发生凋亡,是清除衰老细胞最适宜的思路。在胚胎发育阶段通过细胞凋亡清除多余的和已完成使命的细胞,保证了胚胎的正常发育;在成年阶段通过细胞凋亡清除衰老和病变的细胞,保证了机体的健康。比如,在小鼠研究中发现,当把年老的干细胞置于一个年轻的微环境中,它们能够返老还童(Rescuing replication and osteogenesis of aged mesenchymal stem cells by exposure to a young extracellular matrix Yun Sun,et al.The FASEB Journal,May 2011,vol.25 no.51474-1485),即年轻化,也表示再生能力更强。从另一个方面理解,组织中衰老细胞得以清除,由于特异性的诱导空间存在,组织中的干细胞会自动再生,再生的组织更为年轻化,因此机体整体表现为年轻化。Consciously inducing apoptosis in senescent cells is the most appropriate way to eliminate senescent cells. In the embryonic development stage, the excess and completed mission cells are cleared by apoptosis, which ensures the normal development of the embryo; in the adult stage, the aging and diseased cells are cleared by apoptosis to ensure the health of the body. For example, in mouse studies, it was found that when old stem cells were placed in a young microenvironment, they were able to rejuvenate (Rescuing replication and osteogenesis of aged mesenchymal stem cells by exposure to a young extracellular matrix Yun Sun, et al. The FASEB Journal, May 2011, vol. 25 no. 51474-1485), that is, younger, also means more regenerative capacity. On the other hand, it is understood that the senescent cells in the tissue are removed, and the stem cells in the tissue are automatically regenerated due to the specific induction space, and the regenerated tissue is younger, so the whole body is younger.
有较多研究指出细胞凋亡有助于机体延迟与衰老相关的组织功能丧失。比如,DNA断裂也是细胞凋亡的标志特征,DNA双链断裂(DNA double-strand breaks)在老鼠大脑活动的变化关系表明:这种DNA分子的断裂,即使在完全健康的小鼠神经元中也会发生,在适应新环境过程的小鼠大脑中,DNA断裂的速度是那些待在旧环境中不动小鼠的六倍(Elsa Suberbielle,et al.pHysiologic brain activity causes DNA double-strand breaks in neurons,with exacerbation by amyloid-βNature Neuroscience 16,613–621(2013))。显然适应新环境的小鼠记忆和思维能力更强,这表明DNA双链断裂的这种细胞凋亡过程能够促进小鼠的大脑年轻化。More studies have pointed out that apoptosis helps the body to delay the loss of tissue function associated with aging. For example, DNA fragmentation is also a hallmark of apoptosis. The relationship between DNA double-strand breaks in mouse brain activity indicates that this DNA molecule is broken, even in fully healthy mouse neurons. It happens that in the brains of mice adapted to the new environment, the rate of DNA fragmentation is six times that of mice that are still immobile in the old environment (Elsa Suberbielle, et al. pHysiologic brain activity causes DNA double-strand breaks in neurons , with exacerbation by amyloid-βNature Neuroscience 16, 613–621 (2013)). It is clear that mice adapted to the new environment have stronger memory and thinking ability, which indicates that this apoptotic process of DNA double-strand breaks can promote the brain rejuvenation of mice.
自噬促进了凋亡细胞最终的降解,也是衰老细胞清理的最后一步。自噬增多具有抗衰老效应(Louis R.Lapierre,et al.The TFEB orthologue HLH-30 regulates autopHagy and modulates longevity in Caenorhabditis elegans,Nature Communications.4,Article number:2267)。能引起细胞氧化的因素均能引起细胞凋亡。通过对巨噬细胞和单核细胞的研究,Albina等提出NO也是细胞凋亡的诱导剂(Albina JE,Cui S,Mateo RB et al.Nitric oxide-mediated apoptosis in murine peritoneal macropHages.J Immunol,1993 Jun1;150(11):5080-5)。Autophagy promotes the ultimate degradation of apoptotic cells and is the last step in the clean-up of senescent cells. Increased autophagy has an anti-aging effect (Louis R. Lapierre, et al. The TFEB orthologue HLH-30 regulates autopHagy and modulates longevity in Caenorhabditis elegans, Nature Communications. 4, Article number: 2267). Factors that cause cellular oxidation can cause apoptosis. By studying macrophages and monocytes, Albina et al. proposed that NO is also an inducer of apoptosis (Albina JE, Cui S, Mateo RB et al. Nitric oxide-mediated apoptosis in murine peritoneal macropHages.J Immunol, 1993 Jun1 ;150(11):5080-5).
一氧化氮(NO)对诸多衰老性疾病有治疗作用,比如,,一氧化氮具有防止导致帕金森氏症的神经细胞异常的作用,这其中一氧化氮促进了废弃蛋白质的分解,起到了保护神经细胞的作用(Kentaro Ozawa,et al.S-nitrosylation regulates mitochondrial quality control via activation of parkin Scientific Reports 3,Article number:2202(July2013)。一氧化氮的这种缓解衰老性疾病的机理似乎就是促进衰老细胞发生凋亡。Nitric oxide (NO) has a therapeutic effect on many aging diseases. For example, nitric oxide has a role in preventing neuronal abnormalities that cause Parkinson's disease. Nitric oxide promotes the decomposition of waste proteins and protects them. The role of nerve cells (Kentaro Ozawa, et al. S-nitrosylation regulates mitochondrial quality control via activation of parkin Scientific Reports 3, Article number: 2202 (July 2013). The mechanism of nitric oxide to alleviate aging diseases seems to promote aging The cells undergo apoptosis.
但是现实中却没有发现如何安全方便地靶向清除衰老细胞,而使机体年轻化的技术。 However, in reality, there is no technology that can safely and conveniently target the removal of aging cells and rejuvenate the body.
申请号为201110102598.1的中国专利《紫檀提取物与一氧化氮相结合的护肤品》提到:一氧化氮本身对皮肤的促进再生、抵抗衰老的良好功效,还能增加皮肤对传统化妆品有效成分的吸收。The Chinese patent "Pearl Extract Extracted from Nitric Oxide" with the application number 201110102598.1 mentions that nitric oxide itself promotes regeneration and anti-aging effects on the skin, and also increases the skin's effective ingredients for traditional cosmetics. absorb.
申请号为201210499300.X的专利《一种启动哺乳动物干细胞的方法及二氧化氯在制备用于启动哺乳动物干细胞的药物的应用》,有使用二氧化氯用于启动干细胞从而促进再生,但是没有提及如何通过清除衰老细胞使组织年轻化的机理,也没有可用于药物或化妆品中的抗衰老应用。尽管该专利依据干细胞再生机理提到二氧化氯治疗一些老年性疾病,但是并没有在预防这些疾病方面给出更多方案。Patent No. 201210499300.X, "A Method for Initiating Mammalian Stem Cells and Application of Chlorine Dioxide in the Preparation of Drugs for Initiating Mammalian Stem Cells," uses chlorine dioxide to initiate stem cells to promote regeneration, but does not Reference is made to the mechanism of how to rejuvenate tissues by eliminating senescent cells, and there is no anti-aging application that can be used in medicines or cosmetics. Although the patent refers to chlorine dioxide to treat some senile diseases according to the stem cell regeneration mechanism, it does not give more solutions in preventing these diseases.
癌症和衰老的根源是一样的(Carlos López-Otín,et al.The Hallmarks of Aging.Cell,6 June 2013)。诱导肿瘤细胞凋亡已经成为治疗肿瘤的一个重要途径。如果将肿瘤细胞看作衰老细胞,那么通过诱导肿瘤细胞凋亡从而治疗肿瘤的思路和通过诱导衰老细胞凋亡来抗衰老的思路是一致的。The roots of cancer and aging are the same (Carlos López-Otín, et al. The Hallmarks of Aging. Cell, 6 June 2013). Induction of tumor cell apoptosis has become an important way to treat tumors. If tumor cells are regarded as senescent cells, the idea of treating tumors by inducing apoptosis of tumor cells and anti-aging by inducing apoptosis of senescent cells are consistent.
肿瘤细胞通常具有一定的凋亡抵抗机制,利用细胞凋亡机制针对肿瘤的治疗也就是在凋亡调节的各个水平上使促凋亡和抗凋亡的平衡发生改变,诱导肿瘤细胞凋亡。Tumor cells usually have a certain mechanism of apoptosis resistance, and the apoptosis mechanism is used to treat tumors, that is, to change the balance between pro-apoptosis and anti-apoptosis at various levels of apoptosis regulation, and induce tumor cell apoptosis.
尽管有关凋亡机制的研究在近十多年得到了很大的进展,但能够确切详尽解释细胞凋亡,尤其是哺乳动物细胞凋亡的机制并不多,目前普遍接受的经典途径有以下两条:死亡受体途径和线粒体途径。Although the research on apoptosis mechanism has made great progress in the past ten years, it can explain the apoptosis in detail, especially the mechanism of apoptosis in mammals. There are two commonly accepted classical pathways. Bar: Death receptor pathway and mitochondrial pathway.
针对肿瘤细胞特殊的pH环境,有研究表明,碳酸氢钠增加了肿瘤pH值抑制了自发肿瘤转移(Ian F.Robey,et al.Bicarbonate Increases Tumor pH and Inhibits Spontaneous Metastases Cancer Res March 15,200969;2260),但是其对肿瘤细胞本身并未形成凋亡诱导。In view of the special pH environment of tumor cells, studies have shown that sodium bicarbonate increases tumor pH and inhibits spontaneous tumor metastasis (Ian F. Robey, et al. Bicarbonate Increases Tumor pH and Inhibits Spontaneous Metastases Cancer Res March 15,200969; 2260 ), but it does not form apoptosis induction on tumor cells themselves.
现有的肿瘤细胞凋亡诱导剂有如下几个缺点:靶向性不明确、副作用大、治疗手段复杂且不确定性高、会引起肿瘤细胞的抵抗、只对少数类型肿瘤细胞有效。The existing tumor cell apoptosis inducing agents have the following disadvantages: unclear targeting, large side effects, complicated treatment means and high uncertainty, which may cause resistance of tumor cells, and are effective only for a few types of tumor cells.
如果诱导肿瘤细胞发生凋亡是治疗肿瘤的正确思路,那么需要寻找更具靶向性,更低毒副作用,更具有普适性的细胞凋亡诱导剂。If the induction of apoptosis in tumor cells is the correct way to treat tumors, it is necessary to find more targeted, lower toxic side effects and more universal apoptosis inducers.
二氧化氯是目前国际上公认的新一代的高效、广谱、安全的杀菌、保鲜剂,是氯制剂最理想的替代品,在世界发达国家已得到广泛的应用。美国、西欧、加拿大、日本等发达国家的有关组织如美国环境保护局、食品药品管理局、美国农业部均批准和推荐二氧化氯用于食品、食品加工、制药、医院、公共环境等的消毒、防霉和食品的防腐保鲜等。世界卫生组织 (WHO)和世界粮食组织(FAO)也已将二氧化氯列为A1级安全高效消毒剂。为控制饮水中“三致物质”(致癌、致畸、致突变)的产生,欧美发达国家已广泛应用二氧化氯替代氯气进行饮用水的消毒。但二氧化氯作为药品还未被市场所接受。然而,有部分专利涉及到利用二氧化氯用于美容或治疗疾病的用途(例如,CN102137651A、CN101641104A和CN1199633C、US5750108、CN102441006A),这些专利仍未发现二氧化氯,或者含有二氧化氯的酸性溶液具有清除衰老细胞的潜力。Chlorine dioxide is an internationally recognized new generation of high-efficiency, broad-spectrum, safe sterilization and preservatives. It is an ideal substitute for chlorine preparations and has been widely used in developed countries around the world. Relevant organizations in developed countries such as the United States, Western Europe, Canada, and Japan, such as the US Environmental Protection Agency, the Food and Drug Administration, and the US Department of Agriculture, have approved and recommended the use of chlorine dioxide for disinfection of food, food processing, pharmaceuticals, hospitals, and public environments. Anti-corrosion and preservation of mildew and food. World Health Organization (WHO) and the World Food Organization (FAO) have also listed chlorine dioxide as a Class A1 safe and effective disinfectant. In order to control the production of “three substances” (carcinogenic, teratogenic and mutagenic) in drinking water, chlorine dioxide has been widely used in developed countries in Europe and America to disinfect drinking water. However, chlorine dioxide has not been accepted by the market as a medicine. However, some patents relate to the use of chlorine dioxide for cosmetic or therapeutic use of diseases (eg, CN102137651A, CN101641104A, and CN1199633C, US5750108, CN102441006A), which have not found chlorine dioxide or acidic solutions containing chlorine dioxide. Has the potential to clear aging cells.

具体实施方式detailed description
下面结合具体实施方式对本发明作进一步描述。The invention is further described below in conjunction with specific embodiments.
本发明将细胞凋亡定义为细胞的死亡、并被降解清除,而不严格区分是否属于凋亡(apoptosis)、坏死(necrosis)或自噬(autophagy)。本发明中的诱导衰老细胞和肿瘤细胞凋亡就是指促使衰老细胞死亡、并被降解清除和肿瘤细胞死亡、并被降解清除,而并不细究死亡的方式和过程。The present invention defines apoptosis as the death of a cell and is eliminated by degradation without strictly distinguishing whether it belongs to apoptosis, necrosis or autophagy. Induction of senescent cells and tumor cell apoptosis in the present invention refers to a method and process for causing death of senescent cells, being degraded by clearing and killing of tumor cells, and being degraded by degradation, without diagnosing death.
在描述本发明的具体实施方式之前,首先对本发明所提供方法的机理进行描述。这些描述再结合具体实施例将有助于本领域技术人员理解本发明的技术方案和保护范围。Before describing a particular embodiment of the invention, the mechanism of the method provided by the invention will first be described. These descriptions, in conjunction with the specific embodiments, will help those skilled in the art to understand the technical scope and the scope of the invention.
有研究表明:终身清除衰老细胞,能够延迟与年龄相关的表现型的最初出现时间。而且,晚年的清除会延缓已经出现的与年龄相关的病症的发展。这表明,衰老细胞的确能引起与年龄相关的表现型,而且它们的清除能够防止或延迟与年龄相关的组织功能丧失。(Baker DJ,et al.Clearance of p16Ink4a-positive senescent cells delays ageing-associated disorders.Nature,2011,479:232-236)。可以说,清除衰老细胞,降低衰老细胞的比例,机体就能表现的更为年轻,并且可以防止或者延迟与年龄相关的组织功能丧失。衰老细胞的死亡实质上就是细胞凋亡。(惠宏襄等,《自由基与细胞凋亡》.《生物化学与生物物理进展》,1996;23:12)。Studies have shown that lifetime aging of senescent cells can delay the initial appearance of age-related phenotypes. Moreover, the elimination of later years will delay the development of age-related conditions that have already occurred. This suggests that senescent cells do cause age-related phenotypes and that their clearance prevents or delays age-related loss of tissue function. (Baker DJ, et al. Clearance of p16 Ink4a-positive senescent cells delays ageing-associated disorders. Nature, 2011, 479: 232-236). It can be said that by eliminating aging cells and reducing the proportion of aging cells, the body can be younger and can prevent or delay the loss of age-related tissue function. The death of aging cells is essentially apoptosis. (Hui Hongwei et al., "Free Radicals and Apoptosis". Progress in Biochemistry and Biophysics, 1996; 23:12).
自噬促进凋亡细胞的降解,所以也能起到衰老细胞清除的作用。研究发现,果蝇的记忆缺失能够通过食用富含多胺的食物扭转过来。喂果蝇等吃多胺能够增强生物体的寿命。它似乎通过逆转与年龄相关的自噬的衰退来起作用。自吞噬是指细胞用来清除自身残片的机制。通过基因技术或限制卡路里摄入提高自吞噬,也能够延长果蝇的寿命。(Varun K Gupta,et al.Restoring polyamines protects from age-induced memory impairment in an autopHagy-dependent manner.Nature Neuroscience,01 September 2013)。Autophagy promotes the degradation of apoptotic cells, so it can also play a role in the clearance of senescent cells. The study found that the loss of memory in Drosophila can be reversed by eating foods rich in polyamines. Feeding polyamines such as fruit flies can enhance the lifespan of organisms. It seems to work by reversing the decline in age-related autophagy. Autophagy refers to the mechanism by which cells use to remove their own fragments. Increasing autophagy by genetic technology or limiting calorie intake can also extend the lifespan of fruit flies. (Varun K Gupta, et al. Restoring polyamines protects from age-induced memory impairment in an autopHagy-dependent manner. Nature Neuroscience, 01 September 2013).
高水平的ROS可诱导细胞凋亡(Lau AT,Wang Y,Chiu JF.Reactive oxygen species:current knowledge and applications in cancer research and therapeutic.J Cell Biochem.2008 May 15;104(2):657-67)。研究显示当线虫以生产一氧化氮的细菌为食时,寿命得到显著延长(Ivan Gusarov,et al.Bacterial Nitric Oxide Extends the Lifespan  of C.elegans Cell,Volume 152,Issue 4,818-830,14 February 2013)。这说明氧化物可以促进细胞发生凋亡。High levels of ROS induce apoptosis (Lau AT, Wang Y, Chiu JF. Reactive oxygen species: current knowledge and applications in cancer research and therapeutic. J Cell Biochem. 2008 May 15; 104(2): 657-67) . Studies have shown that lifespan is significantly prolonged when nematodes feed on nitric oxide-producing bacteria (Ivan Gusarov, et al. Bacterial Nitric Oxide Extends the Lifespan Of C.elegans Cell, Volume 152, Issue 4, 818-830, 14 February 2013). This suggests that oxides can promote apoptosis in cells.
尽管抗氧化作为抗衰老的有效标准一直存在,但是现实证据却很少支持。如果无法及时清除缺陷型的蛋白,就会导致蛋白内稳态的丧失,引发衰老相关疾病。例如在阿尔茨海默症中,无法清除的蛋白形成斑块,导致神经元死亡。虽然大量的自由基可能有害,但它们的存在也会触发保护性的应答。没有任何遗传学证据能说明,增强机体的抗氧化防御能够延缓衰老。(Carlos López-Otín,et al.The Hallmarks of Aging.Cell,6 June 2013)。Although anti-oxidation has always existed as an effective standard for anti-aging, the actual evidence is rarely supported. If the defective protein cannot be removed in time, it will lead to the loss of protein homeostasis and cause aging-related diseases. For example, in Alzheimer's disease, proteins that cannot be cleared form plaques, leading to neuronal death. Although a large number of free radicals may be harmful, their presence also triggers a protective response. There is no genetic evidence to suggest that enhancing the body's antioxidant defenses can delay aging. (Carlos López-Otín, et al. The Hallmarks of Aging. Cell, 6 June 2013).
在一些实施例中,本发明也证明了具有较强氧化性物质(二氧化氯)可以促进细胞发生凋亡,并且有助于机体的年轻化。In some embodiments, the present invention also demonstrates that a more oxidizing substance (chlorine dioxide) can promote cell apoptosis and contribute to the rejuvenation of the body.
另一方面,在生长因子依赖的细胞株凋亡过程中普遍存在细胞内酸化,细胞内酸化是细胞凋亡过程中的一种细胞内信号变化,它促进细胞凋亡已有以下几方面的事实所支持:①特异性Na+/H+交换抑制剂通过抑制Na+/H+交换体使细胞内酸化可诱导凋亡,除Na+/H+交换器外,Na+-HCO3 -协同运输器与Cl-/HCO3 -交换器的改变也与细胞凋亡关系密切,细胞浆酸化程度与细胞凋亡发生率存在量效关系;②单纯的碱处理通过减少胞内酸化程度而表现出对抗诱导剂诱导的细胞凋亡;③细胞内存在酸性核酸内切酶,细胞内酸化能激活该酶,触发核小体DNA裂解,该酶是细胞酸化介导细胞凋亡的一个重要物质基础;④许多与细胞凋亡有关的酶和蛋白质的活性在酸性环境中增强(边肖海等,《胞内pH值在细胞凋亡中的研究进展》,《长治医学院学报》2004年4期)。On the other hand, intracellular acidification is prevalent in the growth factor-dependent cell line apoptosis. Intracellular acidification is an intracellular signal change in the process of apoptosis. It promotes apoptosis and has the following facts. Supported: 1 specific Na + /H + exchange inhibitor can induce apoptosis by inhibiting Na + /H + exchanger by intracellular acidification, in addition to Na + /H + exchanger, Na + -HCO 3 - coordinated transport The change of the device and the Cl - /HCO 3 - exchanger is also closely related to apoptosis. There is a dose-effect relationship between the degree of cytoplasmic acidification and the incidence of apoptosis. 2 Simple alkali treatment shows resistance by reducing the degree of intracellular acidification. Inducer-induced apoptosis; there are acidic endonucleases in 3 cells, and intracellular acidification can activate the enzyme to trigger cleavage of nucleosome DNA, which is an important material basis for cell acidification-mediated apoptosis; The activity of many enzymes and proteins involved in apoptosis is enhanced in an acidic environment (Bian Xiaohai et al., "Research progress in intracellular pH in apoptosis", Journal of Changzhi Medical College, 2004, 4).
衰老或者凋亡细胞在酸性的条件下更容易走向死亡。凋亡细胞糖酵解作用加强,酸性代谢产物增多,如果外部施加酸压力(降低pH值),凋亡细胞将加速走向死亡。比如,心肌肥大是心肌组织对负荷增加的一种防御性反应,以暂时适应总体或局部心肌应力的改变,如果心脏生理机能的需要超过心肌细胞的代偿适应能力,心肌细胞将发生自杀性死亡即细胞凋亡,成为心肌肥大向心力衰竭转化的主要机制之一。在缺氧时,肥大心肌细胞糖酵解率仅轻度下降,但在复氧后糖酵解率迅速升高,呈爆发样达峰值后又逐渐恢复到缺氧前水平。糖酵解率的升高必然引起细胞内乳酸酸中毒。常氧培养时肥大心肌细胞凋亡率即显著高于正常心肌细胞,二者在缺氧后的细胞凋亡均显著增加,复氧后正常心肌细胞凋亡逐渐减少,而肥大心肌细胞在复氧早期细胞凋亡率继续大幅度上升,此后逐渐减少。(冯兵,刘伟,徐静,何作云,杨惠标,《缺氧复氧时肥大心肌细胞凋亡及其与能量代谢途径转换的关系》,Acta pHysiologica Sinica,October 25,2005,57(5):636-642)Aging or apoptotic cells are more likely to die under acidic conditions. Apoptotic cells have enhanced glycolysis and increased acidic metabolites. If externally applied acid pressure (lower pH), apoptotic cells will accelerate toward death. For example, cardiac hypertrophy is a defensive response of myocardial tissue to increased load to temporarily adapt to changes in overall or local myocardial stress. If the need for cardiac physiology exceeds the compensatory capacity of cardiomyocytes, suicide death occurs in cardiomyocytes. That is, apoptosis is one of the main mechanisms for the conversion of cardiac hypertrophy to heart failure. In the absence of oxygen, the rate of glycolysis in hypertrophic cardiomyocytes decreased only slightly, but the rate of glycolysis increased rapidly after reoxygenation, and then reached the peak of the burst and then gradually returned to the level before hypoxia. An increase in the rate of glycolysis inevitably causes intracellular lactic acidosis. The apoptotic rate of hypertrophic cardiomyocytes was significantly higher than that of normal cardiomyocytes during normoxia culture. The apoptosis of both cardiomyocytes was significantly increased after hypoxia. After reoxygenation, the apoptosis of normal cardiomyocytes was gradually reduced, while the hypertrophic cardiomyocytes were reoxygenated. The rate of early apoptosis continued to increase substantially and gradually decreased thereafter. (Feng Bing, Liu Wei, Xu Jing, He Zuoyun, Yang Huibiao, "The relationship between hypertrophic cardiomyocyte apoptosis and energy metabolism pathway transition during hypoxia-reoxygenation", Acta pHysiologica Sinica, October 25, 2005, 57(5): 636-642)
肌酸(creatine)在生物化学中,是一种自然存在于脊椎动物体内的一种含氮的有机酸, 能够辅助为肌肉和神经细胞提供能量。研究发现,口服肌酸能够改善G93A转基因小鼠(肌萎缩性脊髓侧索硬化症)机体性能,并延长寿命,该种作用呈现量效关系,同时还保护小鼠运动神经元和黑质神经元的损伤(Klivenyi P,et al.Neuroprotective effects of creatine in a transgenic animal model of amyotropHic lateral sclerosis..Nature Medicine.1999.mar,5(3):347–350)。研究也发现硫辛酸(lipoic acid)能够减缓衰老过程。In biochemistry, creatine is a nitrogen-containing organic acid naturally present in vertebrates. Can assist in providing energy to muscles and nerve cells. Studies have found that oral creatine can improve the body performance and prolong life of G93A transgenic mice (muscle atrophic lateral sclerosis), which has a dose-effect relationship and also protects mouse motor neurons and substantia nigra neurons. Klivenyi P, et al. Neuroprotective effects of creatine in a transgenic animal model of amyotrop Hic lateral sclerosis.. Nature Medicine. 1999. mar, 5(3): 347-350). Studies have also found that lipoic acid can slow down the aging process.
普遍认为L-抗坏血酸的抗衰老作用在于其抗氧化能力。但是,2009年,由德国耶拿大学的迈克尔·瑞斯托实验室进行的重要实验表明ROS对于维持肝脏的基本功能必不可少。实验结果表明,体育锻炼通过提高来自线粒体(细胞内产能的微小器官,产能原理部分经由氧化还原链)内的电子传递链体系ROS的产生,阻止Ⅱ型糖尿病的发生。然而如果同时每天服用抗氧化剂维生素C和维生素E,锻炼就没有积极的效果。2009年2月出版的《临床营养》就发表了一篇综述,总结了总参与人数多达十几万的22项公开发表的随机双盲对照研究,结论是没有支持“抗氧化剂防止冠状动脉硬化”的说法。而《美国医学会杂志》2007年2月发表的一篇综述更加打击抗氧化剂保健品。对总共涉及23万多人的68项研究进行总结,分析的几种抗氧化剂对于死亡率没有影响。如果剔除那些质量不高的研究,只对47项总计超过18万人参与的高质量研究进行分析,那么这几种抗氧化剂甚至小幅度增加了死亡率。因此,本发明人认为,L-抗坏血酸的抗衰老作用在于其酸性。It is generally believed that the anti-aging effect of L-ascorbic acid lies in its antioxidant capacity. However, in 2009, important experiments conducted by the Michael Resto laboratory at the University of Jena, Germany, showed that ROS are essential for maintaining the basic functions of the liver. The experimental results show that physical exercise prevents the occurrence of type 2 diabetes by increasing the production of ROS from the electron transport chain system within the mitochondria (the tiny organ of intracellular production, the principle of production through the redox chain). However, if you take the antioxidants vitamin C and vitamin E every day, exercise has no positive effect. A review of Clinical Nutrition published in February 2009 summed up 22 published randomized, double-blind, controlled trials with a total of more than 100,000 participants. The conclusion was that there was no support for "antioxidants to prevent coronary arteriosclerosis." "The saying." A review published in the February 2007 issue of the Journal of the American Medical Association is more resistant to antioxidant health products. A total of 68 studies involving more than 230,000 people were summarized and several antioxidants analyzed had no effect on mortality. If only those low-quality studies were excluded and only 47 high-quality studies involving more than 180,000 people were analyzed, these antioxidants even increased mortality slightly. Therefore, the inventors believe that the anti-aging effect of L-ascorbic acid lies in its acidity.
多种酸性物质有美容的作用。比如,以30%高浓度的水杨酸作为化学换肤的药剂,可达到和70%果酸换肤相同的淡化色素斑、缩小毛孔、去除细小皱纹及改善日晒引起的老化等多项效果。皮肤美容就是让皮肤年轻化,所以大致可以得出结论,酸性物质能够清除衰老细胞,促进年轻皮肤再生。中剂量和高剂量柠檬酸处理组引起了小鼠睾丸组织细胞的凋亡(王艳杰:柠檬酸对小鼠睾丸组织凋亡的影响[D];河南科技大学:2012年)。A variety of acidic substances have a cosmetic effect. For example, with 30% high concentration of salicylic acid as a chemical peeling agent, it can achieve the same effect as lightening pigmentation spots, shrinking pores, removing fine wrinkles and improving aging caused by sun exposure with 70% acid acid peeling. . Skin beauty is to make the skin younger, so it can be concluded that acidic substances can remove aging cells and promote young skin regeneration. The medium-dose and high-dose citric acid treatment groups caused apoptosis in mouse testicular tissue cells (Wang Yanjie: Effect of citric acid on apoptosis of mouse testis tissue [D]; Henan University of Science and Technology: 2012).
发明人猜想,L-抗坏血酸,肌酸,硫辛酸等酸性物质能够抗衰老的作用,更多的是因为其酸性特征能够加速衰老细胞发生凋亡,从而引起机体年轻化。发明人意外的发现,用有较高氧化电位的二氧化氯液剂并辅以酸性环境能够抗衰老。The inventors suspect that acidic substances such as L-ascorbic acid, creatine, and lipoic acid can resist aging, and more because their acidic characteristics can accelerate the apoptosis of senescent cells, causing the body to rejuvenate. The inventors have unexpectedly discovered that anti-aging can be achieved by using a chlorine dioxide solution having a higher oxidation potential and supplemented by an acidic environment.
在一些实施例中,本发明通过试验证明了,酸性环境有助于提高二氧化氯制剂对细胞的凋亡作用。In some embodiments, the present invention demonstrates through experiments that an acidic environment contributes to an increase in the apoptotic effect of a chlorine dioxide formulation on cells.
在本发明的多个实施例中,我们采用酸性二氧化氯溶液靶向给予目标组织,证明可以使目标组织年轻化。In various embodiments of the invention, we targeted the administration of the target tissue with an acidic chlorine dioxide solution, demonstrating that the target tissue can be rejuvenated.
肿瘤细胞有十大特征:自给自足生长信号(Self-Sufficiency in Growth Signals);抗生长信号的不敏感(Insensitivity to Antigrowth Signals);抵抗细胞死亡(Resisting Cell  Death);潜力无限的复制能力(Limitless Replicative Potential);持续的血管生成(Sustained Angiogenesis);组织浸润和转移(Tissue Invasion and Metastasis);避免免疫摧毁(Avoiding Immune Destruction);促进肿瘤的炎症(Tumor Promotion Inflammation);细胞能量异常(Deregulating Cellular Energetics);基因组不稳定和突变(Genome Instability and Mutation)。Hanahan D,Weinberg RA.Hallmarks of cancer:the next generation.Cell.2011 Mar 4;144(5):646-74)。如果抑制其抵抗细胞死亡,也就是诱导肿瘤细胞凋亡,很大程度抑制了癌症的发生。从逻辑上考虑,由于肿瘤细胞是非正常细胞,机体自身天生应该对其有抑制作用,也就是这些细胞应该自动发生凋亡,之所以不发生凋亡与其自身特征有关。研究发现,一些癌症或许不能完全归因为遗传损伤,而是衰老细胞绕过了告诉它们停止生长的开关所引起,衰老细胞与癌细胞之间的行为存在相似之处表明,如果衰老细胞设法逃脱死亡,它们有潜力变为癌症(Hazel A.Cruickshanks,et al.Senescent cells harbour features of the cancer epigenome,Nature Cell Biology(2013))。新的观点认为,癌症和衰老的根源是一样的(Carlos López-Otín,et al.The Hallmarks of Aging.Cell,6 June 2013)。发明人将肿瘤细胞看作衰老细胞,它理应走向凋亡。因此发明人认为,肿瘤细胞是因为具有的一些特殊能力让其不走向凋亡,而长期滞留在机体内。Tumor cells have ten characteristics: Self-Sufficiency in Growth Signals; Insensitivity to Antigrowth Signals; Resisting Cell Death); Limitless Replicative Potential; Sustained Angiogenesis; Tissue Invasion and Metastasis; Avoiding Immune Destruction; Promoting Tumor Inflammation (Tumor Promotion) Inflammation); Degegulating Cellular Energetics; Genome Instability and Mutation. Hanahan D, Weinberg RA. Hallmarks of cancer: the next generation. Cell. 2011 Mar 4; 144(5): 646-74). If it inhibits its resistance to cell death, that is, induces tumor cell apoptosis, it greatly inhibits the occurrence of cancer. Logically, since tumor cells are abnormal cells, the body itself should be inhibited by it, that is, these cells should automatically undergo apoptosis, and the reason why apoptosis does not occur is related to its own characteristics. The study found that some cancers may not be completely attributed to genetic damage, but that aging cells bypass the switch that tells them to stop growing. The similarities between behaviors between senescent cells and cancer cells suggest that if aging cells manage to escape death They have the potential to become cancer (Hazel A. Cruickshanks, et al. Senescent cells harbour features of the cancer epigenome, Nature Cell Biology (2013)). The new view is that the root causes of cancer and aging are the same (Carlos López-Otín, et al. The Hallmarks of Aging. Cell, 6 June 2013). The inventors regard tumor cells as senescent cells, which should be directed toward apoptosis. Therefore, the inventors believe that tumor cells are left in the body for a long time because of their special ability to prevent apoptosis.
针对肿瘤细胞的两个特征也许是消灭肿瘤的最佳方式。该两个特征就是,抵抗细胞死亡和细胞能量异常。参考诱导衰老细胞发生凋亡的思路同样适用于肿瘤细胞。尽管肿瘤细胞有自身的特征,一般癌症病人存在是由于肿瘤细胞不在机体环境作用下自动走向死亡,但是相对于正常的细胞,肿瘤细胞本身发生了变化,比如更怕氧化物,也更怕酸性环境。Two features for tumor cells may be the best way to destroy tumors. These two features are resistance to cell death and abnormal cellular energy. The same applies to the induction of apoptosis in senescent cells. Although tumor cells have their own characteristics, the general cancer patients exist because tumor cells do not automatically die under the action of the body environment, but compared with normal cells, the tumor cells themselves have changed, such as being more afraid of oxides and more afraid of acidic environment. .
通过口服西地那非治疗3例患有囊状淋巴管瘤的儿童,通过用药,3位患儿的肿瘤体积均出现明显的缩小(Glenda L.et al.Swetman,Sildenafil for Severe LympHatic Malformations N Engl J Med 2012;366:384-386 January 26,2012)。西地那非是5-磷酸二酯酶抑制剂,磷酸二酯酶是NO-cGMP通路的负调节因子,因此西地那非能够通过释放生物活性物质一氧化氮。因此,本发明人认为一氧化氮这种氧化物起到抑制肿瘤的直接作用。Three children with cystic lymphangioma were treated with oral sildenafil, and the tumor volume of the three children was significantly reduced by medication (Glenda L. et al. Swetman, Sildenafil for Severe LympHatic Malformations N Engl J Med 2012;366:384-386 January 26,2012). Sildenafil is a 5-phosphodiesterase inhibitor, and phosphodiesterase is a negative regulator of the NO-cGMP pathway, so sildenafil is able to release nitric oxide, a biologically active substance. Therefore, the inventors believe that nitric oxide, an oxide, acts as a direct inhibitor of tumors.
在针对乳腺和黑素瘤癌细胞的实验中发现,硝酸甘油通过产生一氧化氮可以加强一般化疗药物杀死癌细胞的作用(Barsoum IB,et al.Hypoxia induces escape from innate immunity in cancer cells via increased expression of ADAM10:role of nitric oxide.Cancer Res.2011 Dec 15;71(24):7433-41)。促一氧化氮释放的前体药物,诱导乳腺癌癌细胞死亡,同时保留正常乳腺上皮细胞(Vanity McMurtry,et al.JS-K,a nitric oxide-releasing pro-drug,induces breast cancer cell death while sparing normal  mammary epithelial cells,International of journal of oncology,Published online on:Tuesday,January 25,2011,Pages:963-971)。普遍认为,高浓度的一氧化氮合酶表达,可以对肿瘤细胞产生抑制其生长的毒性作用(Xu W,et al.The role of nitric oxide in cancer.Cell Res.2002 Dec;12(5-6):311-20)。In experiments with breast and melanoma cancer cells, it was found that nitroglycerin can enhance the action of common chemotherapeutic drugs to kill cancer cells by producing nitric oxide (Barsoum IB, et al. Hypoxia induces escape from innate immunity in cancer cells via increased Expression of ADAM10: role of nitric oxide. Cancer Res. 2011 Dec 15;71(24):7433-41). A prodrug that promotes nitric oxide release, induces death of breast cancer cells while retaining normal mammary epithelial cells (Vanity McMurtry, et al. JS-K, a nitric oxide-releasing pro-drug, induces breast cancer cell death while sparing Normal Mammary epithelial cells, International of journal of oncology, Published online on: Tuesday, January 25, 2011, Pages: 963-971). It is generally believed that high concentrations of nitric oxide synthase can produce toxic effects on tumor cells that inhibit their growth (Xu W, et al. The role of nitric oxide in cancer. Cell Res. 2002 Dec; 12 (5-6 ): 311-20).
细胞增殖实验显示,400μmol/L、800μmol/L、1600μmol/L对体外培养的Hela细胞有不同程度的细胞毒性,最高达89.0%。过氧化氢处理后,细胞衰老率和活性氧产生水平随过氧化氢浓度升高而增高,呈现量效关系。结论:过氧化氢对Hela细胞有明显的细胞毒性,还能诱导其衰老和影响活性氧的产生水平。Cell proliferation experiments showed that 400μmol/L, 800μmol/L and 1600μmol/L had different degrees of cytotoxicity to Hela cells cultured in vitro, up to 89.0%. After hydrogen peroxide treatment, the cell senescence rate and the level of reactive oxygen species increased with the increase of hydrogen peroxide concentration, showing a dose-effect relationship. Conclusion: Hydrogen peroxide has obvious cytotoxicity to Hela cells, and can induce its senescence and affect the production of reactive oxygen species.
肿瘤细胞和衰老细胞一样,更多的是依靠低氧的糖酵解方式提供能量。早在80多年前就发现肿瘤细胞的糖代谢较正常细胞旺盛,而且即使是在有氧条件下也依赖于糖酵解,该现象称为“Warburg效应”,其机制与肿瘤细胞的细胞膜上的葡萄糖转运蛋白(Glut)功能活跃,且己糖激酶活性增强有关。“Warburg效应”的结果是细胞产生大量糖酵解产物——乳酸。从糖脱下来的大量H+不能像有氧氧化那样经过呼吸链氧化为水,大量的H+聚集将使细胞内面临pH(pHi)酸化和发生凋亡的威胁,而肿瘤细胞增强的泌酸功能使细胞内pHi得以维持,但对周围正常的宿主细胞将产生不利影响。肿瘤细胞的“Warburg效应”使肿瘤细胞比正常细胞产生更多的酸,但对肿瘤细胞pH检测发现细胞内pHi值较正常细胞无明显区别,而细胞外pH(pHe)和细胞内酸性囊泡内的pH(pHv)明显低于正常细胞,提示可能与肿瘤细胞有较强的泌酸功能有关。(Izumi H,Torigoe T,Ishiguchi H,et al.Cellular pH regulators:potentially promising molecular targets for cancer chemotherapy.Cancer Treat Rev,2003,29(6):541-549)。Like aging cells, tumor cells rely more on low-oxygen glycolysis to provide energy. It was discovered more than 80 years ago that the glucose metabolism of tumor cells is stronger than that of normal cells, and even under aerobic conditions, it depends on glycolysis. This phenomenon is called "Warburg effect", and its mechanism is related to the cell membrane of tumor cells. Glucose transporter (Glut) is active and is involved in increased hexokinase activity. The result of the "Warburg effect" is that the cells produce a large amount of glycolysis product, lactic acid. A large amount of H + removed from sugar cannot be oxidized into water through the respiratory chain like aerobic oxidation, and a large amount of H + aggregation will threaten the pH (pHi) acidification and apoptosis in the cells, while the tumor cells enhance the acid secretion. The function allows the pHi in the cell to be maintained, but will have an adverse effect on the surrounding normal host cells. The "Warburg effect" of tumor cells causes tumor cells to produce more acid than normal cells, but the pH value of tumor cells is found to be indistinguishable from normal cells, while extracellular pH (pHe) and intracellular acidic vesicles. The pH inside (pHv) is significantly lower than that of normal cells, suggesting that it may be related to the strong acid function of tumor cells. (Izumi H, Torigoe T, Ishiguchi H, et al. Cellular pH regulators: potentially promising molecular targets for cancer chemotherapy. Cancer Treat Rev, 2003, 29(6): 541-549).
为了躲避酸性微环境的毒性,肿瘤细胞遂向外排出氢离子,最终产生细胞外的酸性环境以及细胞内的碱性环境。肿瘤细胞通过上调细胞质膜的氢离子相关转运蛋白,如钠氢交换蛋白(Na+/H+)、Na+/K+-ATPase、囊泡型H+-ATPases、H+/CI-共输送体和单羧酸转运蛋白(MCT)等,来实现这一机制(Harguindey S,et al.The role of pH dynamics and the Na+/H+antiporter in the etiopathogenesis and treatment of cancer.Two faces of the same coin--one single nature,[J].Biochim BiopHys Acta,2005,1756(1):1-24)。In order to avoid the toxicity of the acidic microenvironment, the tumor cells excrete hydrogen ions outward, eventually producing an extracellular acidic environment and an alkaline environment inside the cells. Tumor cells regulate hydrogen ion-associated transporters of the plasma membrane, such as sodium-hydrogen exchange protein (Na + /H + ), Na + /K + -ATPase, vesicular H + -ATPases, H + /CI - co-transporters And monocarboxylic acid transporter (MCT), etc., to achieve this mechanism (Harguindey S, et al. The role of pH dynamics and the Na+/H+antiporter in the etiopathogenesis and treatment of cancer. Two faces of the same coin- -one single nature, [J]. Biochim BiopHys Acta, 2005, 1756(1): 1-24).
因此,发明人判断如果通过增加压力让肿瘤细胞泌酸功能降低,那就会引起肿瘤细胞内pHi降低,使其酸中毒,从而诱导肿瘤细胞凋亡。而增加压力,即使肿瘤细胞外环境的pH(pHe)降低,让肿瘤细胞的运输H+离子的质子泵增加压力,并最终崩溃。Therefore, the inventors judged that if the acid secretion function of the tumor cells is lowered by increasing the pressure, the pHi in the tumor cells is lowered, causing acidosis, thereby inducing apoptosis of the tumor cells. While increasing the pressure, even if the pH (pHe) of the tumor's extracellular environment is lowered, the proton pump that transports the H + ions of the tumor cells increases the pressure and eventually collapses.
有较多的文献支持,酸性环境能够诱导肿瘤细胞发生凋亡。比如,酸性环境,通过p53 介导诱导人腺癌和胃癌的细胞株凋亡(A C Williams,et al.An acidic environment leads to p53 dependent induction of apoptosis in human adenoma and carcinoma cell lines:implications for clonal selection during colorectal carcinogenesis,Oncogene.1999May 27;18(21):3199-204)。There is more literature support, and the acidic environment can induce apoptosis in tumor cells. For example, an acidic environment, through p53 A C Williams, et al. An acidic environment leads to p53 induction of apoptosis in human adenoma and carcinoma cell lines:implications for clonal selection during colorectal carcinogenesis,Oncogene.1999May 27;18(21):3199-204).
实验表明:给予体外培养的胃癌AGS细胞一个pH为6.0的酸性环境,这种酸性环境使细胞外H+离子浓度升高,可能通过抑制肿瘤细胞的NHE-1的Na+-H+交换功能使细胞内糖酵解产生的过多H+离子无法排出使本来偏碱性的细胞内环境明显酸化,这样既起到了改变胃癌细胞外环境的作用,同时也改变了细胞内环境。胃癌细胞的这种内外环境的酸化作用改变了适合它生长增殖的细胞内外环境的酸碱度,从而使大部分胃癌细胞停止增殖(高艳等,《胃癌A G S细胞内pH值的测定及酸性环境对其增殖和凋亡的影响》,《现代生物医学进展》,2008年09期)。Experiments have shown that gastric cancer AGS cells cultured in vitro have an acidic environment with a pH of 6.0. This acidic environment increases the concentration of extracellular H + ions, possibly by inhibiting the Na + -H + exchange function of NHE -1 in tumor cells. Excessive H + ions produced by intracellular glycolysis cannot be discharged to significantly acidify the otherwise alkaline environment, which not only changes the extracellular environment of gastric cancer, but also changes the intracellular environment. The acidification of this internal and external environment of gastric cancer cells changes the pH of the cells inside and outside the environment suitable for its growth and proliferation, so that most gastric cancer cells stop proliferating (Gao Yan et al., "Measurement of pH in gastric cancer AGS cells and acidic environment Effects of Proliferation and Apoptosis, Progress in Modern Biomedicine, 2008, 09).
Rich IN等证明了从白血病患者体内获得的白细胞系及外周淋巴血细胞有着比正常造血组织细胞普遍的、具有统计学意义的高的pH值。说明了在胞内pH值与正常造血细胞和白血病细胞的细胞周期调控之间存在一种直接的关系。利用这种关系,他们用Na+/H+交换体的抑制剂5-(N,N-hexamethylene)-amiloride(HMA)处理白血病细胞,降低了胞内pH值,从而诱导了细胞凋亡。(Rich IN,Worthington-White D,Garden OA,Musk P.Apoptosis of leukemic cells accompanies reduction in intracellular pH after targeted inhibition of the Na+/H+exchanger.Blood.2000,15,95(4):1427~1434)。Rich IN et al. demonstrated that leukocyte lines and peripheral lymphocytes obtained from leukemia patients have a statistically high pH value that is more common than normal hematopoietic tissue cells. This illustrates a direct relationship between intracellular pH and cell cycle regulation of normal hematopoietic and leukemia cells. Using this relationship, they treated leukemia cells with the Na + /H + exchanger inhibitor 5-(N,N-hexamethylene)-amiloride (HMA), which reduced intracellular pH and induced apoptosis. (Rich IN, Worthington-White D, Garden OA, Musk P. Apoptosis of leukemic cells accompanies reduction in intracellular pH after targeted inhibition of the Na+/H+exchanger. Blood. 2000, 15, 95(4): 1427~1434) .

本领域技术人员均理解强氧化剂和酸性环境对正常细胞有损伤作用,也就是说,酸性二氧化氯溶液对正常细胞也有加速凋亡作用。但是,本发明人认为,正常细胞的损伤会刺激机体干细胞的再生,因此一般性损伤可以完全被修复;另外,衰老细胞或癌细胞是功能不全的细胞,他们抵御氧化剂或酸性环境的凋亡诱导能力更弱。因此本发明的技术方案是靶向明确而副作用较小的一种抗衰老或抗肿瘤的技术。Those skilled in the art understand that strong oxidants and acidic environments have a damaging effect on normal cells, that is, acidic chlorine dioxide solution also accelerates apoptosis in normal cells. However, the inventors believe that normal cell damage stimulates the regeneration of body stem cells, so that general damage can be completely repaired; in addition, senescent cells or cancer cells are dysfunctional cells that resist apoptosis in oxidants or acidic environments. The ability is weaker. Therefore, the technical solution of the present invention is an anti-aging or anti-tumor technique with targeted and less side effects.
在一些实施例中,本发明证明了酸性二氧化氯制剂对衰老细胞或肿瘤细胞具有更强的凋亡诱导作用,而对正常细胞损伤较小,或者说这种损伤是在可以被弥补的程度。In some embodiments, the present invention demonstrates that an acidic chlorine dioxide formulation has a greater apoptosis-inducing effect on senescent cells or tumor cells, but less damage to normal cells, or that the damage is at a level that can be compensated. .

实施例1:含二氧化氯制剂对增生性瘢痕皮肤成纤维细胞凋亡的影响 Example 1: Effect of chlorine dioxide-containing preparation on apoptosis of proliferative scar skin fibroblasts
增生性瘢痕作为一种影响器官功能、美观的疾病,病因有多种,但凡损伤累及真皮深层的损伤,都有可能产生增生性瘢痕。普遍认为成纤维细胞凋亡不足是增生性瘢痕产生的原因(Ogawa,R.The most current algorithms for the treatment and prevention of hypertropHic scars and keloids[J].Plast Reconstr Surg,2010,125:557-568)。常识表明,同样大小的伤口,相对比年轻人,老年人的伤口愈合慢且容易留下疤痕。因此,增生性瘢痕的形成可以理解为一种皮肤老化的现象,通过诱导成纤维细胞凋亡可能是治愈瘢痕性皮肤的好方法。As a kind of disease that affects organ function and appearance, hypertrophic scar has many causes, but any damage that affects deep layers of the dermis may cause hypertrophic scars. It is generally believed that insufficient apoptosis of fibroblasts is the cause of hypertrophic scars (Ogawa, R. The most current algorithms for the treatment and prevention of hypertrop Hic scars and keloids [J]. Plast Reconstr Surg, 2010, 125: 557-568) . Common sense shows that wounds of the same size are relatively slower to heal and tend to leave scars than younger people. Therefore, the formation of hypertrophic scar can be understood as a phenomenon of skin aging, which may be a good way to cure scarred skin by inducing apoptosis of fibroblasts.
1)凋亡试验1) Apoptosis test
增生性瘢痕患者共6例,男5例,女1例,平均年龄42岁。实验共分4组:瘢痕中央部(中央2/3半径范围内)、瘢痕边缘部(周边1/3半径范围内)、瘢痕周围皮肤(距瘢痕疙瘩边缘0.5cm范围内)、瘢痕病人其他部位正常皮肤。There were 6 patients with hypertrophic scars, including 5 males and 1 female, with an average age of 42 years. The experiment was divided into 4 groups: the central part of the scar (within the central 2/3 radius), the edge of the scar (within the radius of 1/3 of the periphery), the skin around the scar (within 0.5 cm from the edge of the keloid), and other parts of the scar patient. Normal skin.
成纤维细胞的培养:所取标本按上述方法分组后在无菌条件下切除其表皮及皮下组织,在少量胎牛血清中将标本切成1mm3左右的组织块,在37℃、5%CO2饱和湿度条件下培养4-6h,使组织块粘附于瓶壁上,然后加入含15%胎牛血清的DMEM(dulbecco's modified eagle medium)培养基适量,3-4天换液1次,2-3周后,原代细胞长满并汇合成片,每3-5天传代1次,实验用第6-8代细胞。Culture of fibroblasts: The specimens were grouped according to the above method, and the epidermis and subcutaneous tissues were excised under aseptic conditions. The specimens were cut into tissue pieces of about 1 mm 3 in a small amount of fetal bovine serum at 37 ° C, 5% CO. 2 Incubate for 4-6 hours under saturated humidity conditions, so that the tissue block adheres to the bottle wall, then add appropriate amount of DMEM (dulbecco's modified eagle medium) containing 15% fetal bovine serum, and change the solution once every 3-4 days, 2 - After 3 weeks, the primary cells were overgrown and pooled into pellets, passaged once every 3-5 days, and cells 6-8 were used for the experiment.
用去离子水配置浓度为7.47%亚氯酸钠和1.59%氯化钠的混合溶液,制备出第一份溶液;用去离子水配置浓度为16.7%的柠檬酸溶液,制备出第二份溶液。分别从不同份溶液的容器中取出相同体积的溶液,混合,等待溶液混合静止3~5分钟,再用0.22μm的双层滤膜过滤,用去离子水稀释,制备不同浓度的二氧化氯酸性溶液。The first solution was prepared by dissolving a mixed solution of 7.47% sodium chlorite and 1.59% sodium chloride in deionized water; a citric acid solution having a concentration of 16.7% was prepared with deionized water to prepare a second solution. . Take the same volume of solution from the different parts of the solution, mix, wait for the solution to mix and stand for 3 to 5 minutes, then filter with 0.22μm double-layer filter, dilute with deionized water to prepare different concentrations of chlorine dioxide. Solution.
细胞接种并施加不同处理因素诱导细胞凋亡。各组分别取一瓶处于对数生长期的细胞,接种于6孔细胞培养板中,每组细胞于每块板接种1个孔(1×105个细胞/孔),共接种6块板24个孔,继续在37℃、5%CO2饱和湿度条件下培养48-72h,至细胞长满孔底,取其中1块板,吸出培养基,用Hank液(一种平衡盐溶液)洗涤后加入不含胎牛血清的DMEM培养基,另取3块板分别加入含二氧化氯制剂,使其终浓度分别达到100ppm、1000ppm、2900ppm,取1块板加入FasMcAb(Fas单抗),使其终浓度达到1μg/ml,另外1块板不施加任何处理因素,继续培养24h后检测其凋亡率。Cells were seeded and different treatment factors applied to induce apoptosis. Each group was taken from a cell in the logarithmic growth phase and inoculated into a 6-well cell culture plate. Each group of cells was seeded with 1 well (1 × 10 5 cells/well) per plate, and a total of 6 plates were inoculated. 24 wells, continue to culture at 37 ° C, 5% CO 2 saturated humidity for 48-72h, until the cells are full of the bottom of the well, take one of the plates, aspirate the medium, wash with Hank liquid (a balanced salt solution) After adding DMEM medium containing no fetal bovine serum, another three plates were added to the chlorine dioxide-containing preparation to achieve a final concentration of 100 ppm, 1000 ppm, and 2900 ppm, respectively, and one plate was added to FasMcAb (Fas mAb). The final concentration reached 1 μg/ml, and the other plate did not apply any treatment factor, and the apoptosis rate was detected after 24 hours of culture.
PI染色、流式细胞仪检测比较各组成纤维细胞的凋亡率。将上述处理过的细胞消化后收集于10ml离心管中,1000r/min离心10min,预冷的PBS(磷酸盐缓冲溶液)洗遍后加入70%乙醇4℃固定过夜,再低速离心10min,PBS洗涤后重悬细胞,在剩余的0.5ml细胞悬液中加 入RNase A 2μl(20mg/ml),37℃孵育30min后立即投入冰浴中停止RNase A作用,再加入500μl PI染液(100μg/ml)避光孵育30min,吹散细胞,300目滤网过滤后在流式细胞仪上进行细胞DNA分析检测细胞凋亡率。PI staining and flow cytometry were used to compare the apoptosis rate of each component fiber cell. The treated cells were digested and collected in a 10 ml centrifuge tube, centrifuged at 1000 r/min for 10 min, washed with pre-cooled PBS (phosphate buffer solution), added with 70% ethanol at 4 ° C overnight, then centrifuged at low speed for 10 min, washed with PBS. Resuspend the cells and add in the remaining 0.5 ml of cell suspension Into RNase A 2μl (20mg/ml), incubate at 37 °C for 30min, immediately put into the ice bath to stop the action of RNase A, then add 500μl PI staining solution (100μg/ml) and incubate for 30min in the dark, blow off the cells, filter through 300 mesh filter Cellular DNA analysis was performed on a flow cytometer to detect apoptosis rate.
所有各组细胞经无血清培养24h后其细胞凋亡率均有不同程度的增高,然而经过比较各组无血清培养后细胞凋亡的增长率,发现正常皮肤显著高于瘢痕疙瘩边缘部(P<0.01),而瘢痕疙瘩周围皮肤和瘢痕疙瘩中央部介于两者之间,与各组比较差异均无显著性意义(P>0.05,表1)。这说明被看作老化组织的瘢痕处具有明显的抗凋亡能力,所以瘢痕组织不仅不能得以自动清除,反而会增生。The apoptosis rate of all the cells was increased after 24 hours of serum-free culture. However, after comparing the growth rate of apoptosis in each group, the normal skin was found to be significantly higher than the edge of keloid. <0.01), and the skin around the keloid and the central part of the keloid were between the two, and there was no significant difference between the two groups (P>0.05, Table 1). This indicates that the scar that is regarded as an aging tissue has obvious anti-apoptotic ability, so the scar tissue can not only be automatically removed, but will proliferate.

FasMcAb作用下正常皮肤的成纤维细胞凋亡率明显高于瘢痕及其周围皮肤成纤维细胞凋亡率(P<0.01,表2)。这也说明瘢痕处组织具有抗凋亡能力。The apoptosis rate of fibroblasts in normal skin under FasMcAb was significantly higher than that in scar and surrounding skin fibroblasts (P<0.01, Table 2). This also indicates that the tissue at the scar has anti-apoptotic ability.

在二氧化氯制剂作用下,四组成纤维细胞凋亡率随着二氧化氯浓度梯度的升高逐步提高,该提高具有显著性(P<0.01,表3)。这说明酸性环境下的二氧化氯制剂对增生性瘢痕组织 具有明显的促凋亡作用。Under the action of chlorine dioxide preparation, the apoptosis rate of the four-component fiber cells gradually increased with the increase of the chlorine dioxide concentration gradient, and the increase was significant (P<0.01, Table 3). This shows the chlorine dioxide preparation in acidic environment for hypertrophic scar tissue Has a significant pro-apoptotic effect.

2)对疤痕的治疗2) Treatment of scars
用去离子水配置浓度为7.47%亚氯酸钠和1.59%氯化钠的混合溶液,制备出第一份溶液;用去离子水配置浓度为16.7%的柠檬酸溶液,制备出第二份溶液。分别从不同份溶液的容器中取出相同体积的溶液,混合,等待溶液混合静止3~5分钟,再用0.22μm的双层滤膜过滤。制备出二氧化氯制剂。The first solution was prepared by dissolving a mixed solution of 7.47% sodium chlorite and 1.59% sodium chloride in deionized water; a citric acid solution having a concentration of 16.7% was prepared with deionized water to prepare a second solution. . The same volume of solution was taken from the containers of different solutions, mixed, and the solution was allowed to stand still for 3 to 5 minutes, and then filtered through a 0.22 μm double-layer filter. A chlorine dioxide preparation was prepared.
使用以上二氧化氯制剂分两次对增生性瘢痕进行治疗,一遍直接用该二氧化氯制剂,第二遍再加等量二甲基亚砜。即两遍都直接涂抹瘢痕处,中间间隔30min,连续涂抹15天。The hypertrophic scar was treated twice with the above chlorine dioxide preparation, the chlorine dioxide preparation was directly used once, and the same amount of dimethyl sulfoxide was added for the second time. That is, the scar is directly applied to the two times, with an interval of 30 minutes in between, and continuous application for 15 days.
治疗后即刻增生性瘢痕呈暗红色,瘢痕表面见均匀分布的灰色至微黄的点状气化皮屑,无明显渗血、渗液。治疗后第一天,创面干燥见红色点状痂皮形成,此后至治疗后第五天,治疗的创面呈鲜红色,创面痂皮逐渐脱落。至治疗后第二十天,治疗创面完全愈合,痂皮全部脱落,同时可观察到瘢痕的中央的乳头状突起高度变得低平,瘢痕处皮肤明显光滑一些,有色素沉着。治疗后25天左右,有光滑的新鲜皮肤生成,在40±20天左右的时间,原来疤痕不规则形状完全平坦。Immediately after treatment, the hypertrophic scar was dark red, and the surface of the scar was uniformly distributed with gray to yellowish punctate gasification dander, and there was no obvious bleeding or exudation. On the first day after treatment, the wound surface was dry and red punctate suede was formed. From then on to the fifth day after treatment, the treated wound surface was bright red, and the wound surface gradually fell off. On the twentieth day after the treatment, the treated wounds completely healed, and the suede all fell off. At the same time, the height of the papillary lobes in the center of the scar was observed to be low, and the skin at the scar was smooth and pigmented. About 25 days after the treatment, smooth fresh skin was formed, and the original irregular shape of the scar was completely flat at about 40±20 days.
取治疗前、治疗后1h、治疗后2天、7天、14天、28天瘢痕,切取疤痕处全层组织,切取组织经4%多聚甲醛固定后常规脱水、石蜡包埋,切片后行HE染色观察各组各时期镜下成纤维细胞形态、密度,胶原纤维排列、毛细血管增生情况,TUNEL(Terminal deoxynucleotidyl transferase dUTP nick end labeling)法检测成纤维细胞凋亡率变化。The scar was taken before treatment, 1 hour after treatment, 2 days, 7 days, 14 days, and 28 days after treatment. The whole layer of the scar was cut, and the tissue was removed by 4% paraformaldehyde, then dehydrated and embedded in paraffin. HE staining was used to observe the morphology, density, collagen fiber arrangement and capillary proliferation of microfibrous cells in each group. TUNEL (Terminal deoxynucleotidyl transferase dUTP nick end labeling) method was used to detect the apoptosis rate of fibroblasts.
采用TUNEL法,染色区域位于细胞核。光镜下观察正常的成纤维细胞细胞核呈蓝色,为阴性反应,凋亡细胞的细胞核呈深浅不一的棕褐色,为阳性反应,即凋亡细胞。40倍光镜下观察,每张切片随机选择3个成纤维细胞阳性细胞数最多的高倍视野进行计数,阳性细胞反 应率(R)=阳性细胞数/细胞总数,结果取平均数。Using the TUNEL method, the stained area is located in the nucleus. Under normal light microscope, the nuclei of normal fibroblasts were blue, which was a negative reaction. The nucleus of apoptotic cells showed a dark brown color, which was a positive reaction, namely apoptotic cells. Under the observation of 40 times light microscope, each slice was randomly selected to have the highest number of positive cells with the highest number of fibroblast positive cells, and the positive cells were reversed. Rate (R) = number of positive cells / total number of cells, and the results were averaged.
在成纤维细胞、角朊细胞、血管内皮细胞中均可见凋亡小体,即凋亡细胞。治疗后即刻即有明显的成纤维细胞凋亡增多表现,治疗后1h、2天、7天、14天、28天治疗组成纤维细胞凋亡率逐渐增高,各时期凋亡率均比治疗前高,P值<0.01,说明差异有统计学意义。Apoptotic bodies, ie apoptotic cells, are found in fibroblasts, keratinocytes, and vascular endothelial cells. Immediately after treatment, there was an obvious increase in fibroblast apoptosis. The apoptosis rate of fibroblasts was gradually increased at 1h, 2 days, 7 days, 14 days, and 28 days after treatment, and the apoptosis rate was higher than that before treatment. P value <0.01, indicating that the difference is statistically significant.

实施例3含二氧化氯制剂治疗痤疮的试验Example 3 Test for the treatment of acne with chlorine dioxide preparation
痤疮是青少年经常反复发作的皮肤问题,主要原因是老化角质层不能及时清除,堵塞毛孔,导致油脂堆积,形成肿胀(粉刺);在痤疮杆菌的侵袭后感染,发红形成脓包。由于二氧化氯本身是高效的杀菌剂,所以只用保证老化角质细胞得到清除,那么二氧化氯就可以治疗痤疮。Acne is a frequent skin problem in adolescents. The main reason is that the aging cuticle cannot be removed in time, clogged pores, causing oil to accumulate and form swelling (acne). After infection by acne bacteria, redness forms pustules. Since chlorine dioxide itself is a highly effective fungicide, it is only used to ensure that aged keratinocytes are removed, so chlorine dioxide can treat acne.

实施例8二氧化氯制剂诱导肿瘤细胞凋亡的试验Example 8 Test for Inducing Apoptosis of Tumor Cells by Chlorine Dioxide Formulation
对结肠癌细胞系LS174T和乳腺癌细胞系Cama-1这两个细胞系的死亡和细胞周期变化进行了分析。分别在不存在二氧化氯或存在100ppm二氧化氯(通过实施例5中的方法制备)的条件下,培养细胞48小时。用1μg/ml溴脱氧尿苷(BrdU)脉冲30分钟后,细胞在70%乙醇中于4℃固定过夜,然后用FITC偶联的抗BrdU单克隆抗体和3μg/ml碘化丙锭染色。通过流式细胞术(FACS)分析细胞死亡和细胞周期。掺入BrdU是一种增殖测量方法,而碘化丙锭染色则可确定DNA含量,特别是正在经历细胞凋亡的近二倍体细胞群体。The death and cell cycle changes of the colon cancer cell line LS174T and the breast cancer cell line Cama-1 were analyzed. The cells were cultured for 48 hours in the absence of chlorine dioxide or in the presence of 100 ppm chlorine dioxide (prepared by the method of Example 5). After 30 minutes of pulsed with 1 μg/ml bromodeoxyuridine (BrdU), the cells were fixed overnight in 70% ethanol at 4 ° C, and then stained with FITC-conjugated anti-BrdU monoclonal antibody and 3 μg/ml propidium iodide. Cell death and cell cycle were analyzed by flow cytometry (FACS). Incorporation of BrdU is a method of proliferation measurement, while propidium iodide staining determines the DNA content, particularly the population of near diploid cells that are undergoing apoptosis.
数据显示,掺入BrdU的LS174T细胞的百分比从处理前的27%变为100ppm二氧化氯制剂存在下培养48小时后的6%。相反,具有近二倍体DNA含量的LS174T细胞的百分比,从处理前的4%变为100ppm二氧化氯制剂存在下培养48小时后的23%,说明100ppm二氧化氯制剂的细胞凋亡促进能力强。The data showed that the percentage of BrdU-incorporated LS174T cells was changed from 27% before treatment to 6% after 48 hours of culture in the presence of 100 ppm chlorine dioxide preparation. In contrast, the percentage of LS174T cells with near diploid DNA content was changed from 4% before treatment to 23% after 48 hours of culture in the presence of 100 ppm chlorine dioxide preparation, indicating the ability of apoptosis promotion of 100 ppm chlorine dioxide preparation. Strong.
数据还显示,掺入BrdU的Cama-1细胞的百分比,由处理前的15%变为100ppm二氧化氯制剂存在下培养48小时后的2%。相反,具有近二倍体DNA含量的Cama-1细胞的百分比,从处理前的4%变为100ppm二氧化氯制剂存在下培养48小时后的17%,表明100ppm二氧化氯制剂引发细胞凋亡。The data also showed that the percentage of Cmad-1 cells spiked with BrdU was changed from 15% before treatment to 2% after 48 hours of incubation in the presence of 100 ppm chlorine dioxide preparation. In contrast, the percentage of Cama-1 cells with near diploid DNA content was changed from 4% before treatment to 17% after 48 hours of culture in the presence of 100 ppm chlorine dioxide preparation, indicating that 100 ppm chlorine dioxide preparation triggered apoptosis. .
这些数据表明,用100ppm二氧化氯制剂处理48小时,LS 174T和Cama-1细胞系停止分裂,并经历细胞凋亡。These data indicate that the LS 174T and Cama-1 cell lines stopped dividing and were subjected to apoptosis after treatment with a 100 ppm chlorine dioxide formulation for 48 hours.
实施例9不同pH值情况下的二氧化氯制剂对肿瘤细胞的凋亡影响Example 9 Effect of Chlorine Dioxide Formulation on Apoptosis of Tumor Cells at Different pH Values
为了进一步研究二氧化氯制剂处理对乳腺肿瘤细胞系的作用,在Cama-1细胞中,通过 膜联蛋白V染色对细胞死亡进行了分析。存在或不存在400ppm二氧化氯制剂(通过实施例5中的方法制备)时培养细胞24小时。通过膜联蛋白V染色和流式细胞术检测细胞凋亡。数据显示,超过70%的Cama-1细胞被膜联蛋白V染色,进一步证明400ppm二氧化氯制剂诱导细胞凋亡。其他条件不变,但将400ppm二氧化氯制剂通过pH调节剂,使其pH值由3.5提高值5.5,则只有超过50%的Cama-1细胞被膜联蛋白V染色,这说明酸性环境有助于提高癌细胞凋亡率。To further investigate the effects of chlorine dioxide preparation on breast tumor cell lines, in Cama-1 cells, Cell death was analyzed by annexin V staining. Cells were cultured for 24 hours with or without the presence of a 400 ppm chlorine dioxide formulation (prepared by the method of Example 5). Apoptosis was detected by annexin V staining and flow cytometry. The data showed that more than 70% of Cama-1 cells were stained with annexin V, further demonstrating that 400 ppm chlorine dioxide preparation induced apoptosis. Other conditions remain the same, but the 400 ppm chlorine dioxide preparation is passed through a pH adjuster to increase the pH from 3.5 to 5.5, and only over 50% of Cama-1 cells are stained with annexin V, indicating that the acidic environment contributes Increase the rate of cancer cell apoptosis.
我们还试图测定二氧化氯诱导细胞凋亡的动力学。500ppm二氧化氯制剂(通过实施例5中的方法制备)存在或不存在时,pH值为3.5,培养Cama-1细胞。30小时后,检测培养物中凋亡细胞(膜联蛋白阳性细胞)的百分比。数据显示,30小时后,未处理细胞显示15%的自发性细胞凋亡。然而,80%用二氧化氯制剂处理的细胞显示细胞死亡。具体地讲,Cama-1细胞中,加入500ppm二氧化氯制剂后9小时便开始二氧化氯引发的细胞凋亡,处理30小时后,凋亡细胞达到80%。其他条件不变,但将500ppm二氧化氯制剂通过pH调节剂使其pH值由3.0提高值6,则只有超过45%的细胞显示死亡,这说明酸性环境有助于提高癌细胞凋亡率。We also attempted to determine the kinetics of chlorine dioxide-induced apoptosis. Cama-1 cells were cultured in the presence or absence of a 500 ppm chlorine dioxide preparation (prepared by the method of Example 5) at a pH of 3.5. After 30 hours, the percentage of apoptotic cells (Annexin positive cells) in the culture was examined. The data showed that after 30 hours, untreated cells showed 15% spontaneous apoptosis. However, 80% of cells treated with the chlorine dioxide formulation showed cell death. Specifically, in Cama-1 cells, chlorine dioxide-induced apoptosis was started 9 hours after the addition of 500 ppm of chlorine dioxide preparation, and after 30 hours of treatment, the apoptotic cells reached 80%. Other conditions were the same, but the 500 ppm chlorine dioxide preparation was adjusted to a pH of 3.0 by a pH adjuster, and only over 45% of the cells showed death, indicating that the acidic environment contributes to an increase in cancer cell apoptosis.
我们于是试图测定二氧化氯制剂对人原代乳腺肿瘤细胞的作用。刚恢复的肿瘤单细胞悬液与PBS或二氧化氯(100ppm)制剂孵育48小时。通过PI染色测定细胞凋亡。百分比表示含有低含量DNA的细胞(subG0/G1细胞)的比例,即凋亡细胞的比例。数据显示,19.5%用PBS处理的细胞具有低含量的DNA,而38.6%用二氧化氯制剂处理的细胞具有低含量的DNA。因此,观察到相似的100ppm二氧化氯制剂对人乳腺原代肿瘤细胞的细胞凋亡作用。其他条件不变,但将100ppm二氧化氯制剂通过pH调节剂,使其pH值由4.5提高值6,则只有25%用二氧化氯制剂处理的细胞具有低含量的DNA。,这说明酸性环境有助于提高癌细胞凋亡率。We then attempted to determine the effect of chlorine dioxide preparations on human primary breast tumor cells. The newly recovered tumor single cell suspension was incubated with PBS or chlorine dioxide (100 ppm) formulation for 48 hours. Apoptosis was determined by PI staining. The percentage indicates the proportion of cells (subG0/G1 cells) containing a low amount of DNA, that is, the proportion of apoptotic cells. The data shows that 19.5% of cells treated with PBS have low levels of DNA, while 38.6% of cells treated with chlorine dioxide preparations have low levels of DNA. Thus, a similar 100 ppm chlorine dioxide formulation was observed to have an apoptotic effect on human breast primary tumor cells. Other conditions were unchanged, but the 100 ppm chlorine dioxide formulation was passed through a pH adjuster to increase the pH from 4.5 to 6, and only 25% of the cells treated with the chlorine dioxide formulation had low levels of DNA. This indicates that the acidic environment helps to increase the apoptosis rate of cancer cells.
结合以上肿瘤体外杀伤试验,本领域技术人员可以判断出,酸性二氧化氯制剂对肿瘤细胞具有明显的杀伤作用,而且这种作用机制是来自于酸性二氧化氯制剂可以显著诱导肿瘤细胞发生凋亡。Combined with the above tumor in vitro killing test, those skilled in the art can judge that the acidic chlorine dioxide preparation has obvious killing effect on tumor cells, and the mechanism of action is that the acidic chlorine dioxide preparation can significantly induce apoptosis of tumor cells. .
实施例10二氧化氯直接对S180荷瘤小鼠抑瘤效果及免疫器官指数的影响Example 10 Effect of Chlorine Dioxide Directly on Tumor Suppressive Effect and Immune Organ Index in S180 Tumor-bearing Mice
用去离子水配置浓度为7.47%亚氯酸钠和1.59%氯化钠的混合溶液,制备出第一份溶液;用去离子水配置浓度为16.7%的柠檬酸溶液,制备出第二份溶液。分别从不同份溶液的容器中取出相同体积的溶液,混合,等待溶液混合静止5~10分钟,再加入等体积90%的二甲基亚砜,再用0.22μm的双层滤膜过滤。定量分别制备出pH=5和pH=3.5的100ppm、500ppm和2000ppm的二氧化氯制剂。The first solution was prepared by dissolving a mixed solution of 7.47% sodium chlorite and 1.59% sodium chloride in deionized water; a citric acid solution having a concentration of 16.7% was prepared with deionized water to prepare a second solution. . The same volume of solution was taken from the containers of different solutions, mixed, and the solution was allowed to stand still for 5 to 10 minutes, then an equal volume of 90% dimethyl sulfoxide was added, and then filtered through a 0.22 μm double-layer filter. 100 ppm, 500 ppm, and 2000 ppm chlorine dioxide formulations of pH = 5 and pH = 3.5 were prepared separately.
昆明小鼠,随机分为8组,每组15只,雌雄各半,分别为:空白对照组,环磷酰胺组, 二氧化氯低、中、高剂量组(pH恒定为5),二氧化氯低剂量(pH=3.5)组、中剂量(pH=3.5)组、高剂量(pH=3.5)组。环磷酰胺ip给药剂量为20mg/kg,二氧化氯瘤内注射低、中、高剂量分别为100ppm、500ppm和2000ppm,空白对照组给予生理盐水。各组小鼠接种S180实体瘤24h后给药,容积为0.1ml/10g,1次/d,连续14d。于停药5日处死小鼠,剥离瘤块及脾和胸腺并称重,计算抑瘤率及脾和胸腺指数。Kunming mice were randomly divided into 8 groups, 15 in each group, male and female, respectively: blank control group, cyclophosphamide group, Low, medium and high doses of chlorine dioxide (pH is constant at 5), low dose chlorine dioxide (pH = 3.5), medium dose (pH = 3.5), high dose (pH = 3.5). The dose of Cyclophosphamide ip was 20 mg/kg, and the low, medium and high doses of chloramphenicol injection were 100 ppm, 500 ppm and 2000 ppm, respectively. The blank control group was given normal saline. Each group of mice was inoculated with S180 solid tumors for 24 hours, and the volume was 0.1 ml/10 g once daily for 14 days. The mice were sacrificed on the 5th day of withdrawal, the tumor mass and the spleen and thymus were removed and weighed, and the tumor inhibition rate and spleen and thymus index were calculated.
由表1可以看出,与空白对照组相比,二氧化氯制剂(高pH值)低、中、高剂量组,环磷酰胺化疗组,以及二氧化氯制剂(低pH值)低、中、高剂量组均可显著抑制S180肿瘤的生长(P<0.05、P<0.01)。与高pH值组相比,二氧化氯制剂低pH值组均可显著提高二氧化氯制剂对S180肿瘤生长的抑制作用(P<0.05)。As can be seen from Table 1, compared with the blank control group, the chlorine dioxide preparation (high pH) low, medium and high dose groups, cyclophosphamide chemotherapy group, and chlorine dioxide preparation (low pH) are low, medium High-dose group significantly inhibited the growth of S180 tumors (P<0.05, P<0.01). Compared with the high pH group, the low pH group of chlorine dioxide preparation can significantly increase the inhibitory effect of chlorine dioxide preparation on S180 tumor growth (P<0.05).

由表14可以看出,与空白对照组相比,环磷酰胺化疗组小鼠的胸腺、脾脏指数显著性降低(P<0.01),说明化疗手段的副作用很大。二氧化氯制剂中、高剂量组小鼠的胸腺和脾脏指数都显著性增高(P<0.05)。针对高低pH值,二氧化氯的影响不显著。说明二氧化氯促进肿瘤凋亡过程中对免疫器官的副作用微乎其微。As can be seen from Table 14, compared with the blank control group, the thymus and spleen index of the mice in the cyclophosphamide chemotherapy group were significantly decreased (P<0.01), indicating that the side effects of chemotherapy were great. The thymus and spleen index of the mice in the high-dose group of chlorine dioxide were significantly increased (P<0.05). For high and low pH values, the effect of chlorine dioxide is not significant. It shows that the side effects of immune dioxide on the process of apoptosis induced by chlorine dioxide are minimal.
