Definitions
- composition for promoting erythropoiesis and its use please request a Chinese invention patent submitted on September 27, 2012
- the present invention relates to the field of pharmacy, and in particular to a pharmaceutical composition or a dietary supplement composition for promoting erythropoiesis, and for preventing and treating anemia and/or anoxia, and JL: Chuan Tu. Background technique
- Red blood cells are mainly produced in the bone marrow of the human body (especially red bone marrow), and the thousand cells in the fj' marrow are first differentiated into erythroid progenitor cells, in erythropoietin.
- Erythropoietin also known as erythropoietin
- K forms mature red blood cells.
- Erythropoietin in the human body is a hormone-like substance secreted by the kidneys and liver.
- Anemia refers to the reduction of red blood cell volume in human peripheral blood, which is lower than the lower limit of the normal range - a common clinical symptom.
- Anemia includes chemotherapy-induced anemia (CIA) and anemia.
- chemotherapy drugs kill a large number of cancer cells, and also kill: ⁇ [ ⁇ : often organize cells and cause varying degrees of sputum inhibition, so chemotherapy drugs can inhibit bone marrow Hematopoietic cells cause anemia. More than 60% of cancer patients are loyal to anemia after receiving chemotherapy, which seriously reduces the patient's body function and quality of life.
- chemotherapeutic drugs cause stomach discomfort, causing vomiting and nausea, severely affecting appetite and causing the patient's body: : Relief, one of the primary difficulties is chemotherapy-induced anemia (CIA).
- Yin anemia refers to the deficiency of renal erythropoietin production caused by various oxysera or urinary sputum in plasma.
- I anemia caused by the formation and metabolism of red blood cells, the chronic ⁇ function does not occur until the end stage Common complications.
- Reduced erythropoiesis shortened red blood cell count, and increased red blood cell loss in patients, affecting the patient's blood metabolic cycle.
- chemotherapy-induced anemia and renal anemia is blood transfusion and dialysis, ii ⁇ is transfusion may bring strict : The clinical or subclinical side effects, the patient will also suffer great pain in the process of receiving treatment.
- Hypoxia is a pathological process that causes abnormal changes in the metabolism, function, and morphological structure of tissues due to insufficient oxygen supply to the tissue or kawanoxia.
- Hypoxia - general manifestations dizziness, headache, tinnitus, vertigo, weak limbs; or nausea, vomiting, palpitation, shortness of breath, shortness of breath, rapid heartbeat.
- Erythrocytes are the most important medium for transporting oxygen through the blood in vertebrates, so increasing the red blood cells in the body: 3 ⁇ 4 can effectively improve the hypoxic state (see reference: "Therapeutic effect of erythropoietin on neonatal hypoxic ischemic encephalopathy" Analysis, Guo Zhimei et al, Clinical Military Medical Journal, 2008, 5 "and” EPO on the expression of NSE in neonatal rats with hypoxic-ischemic brain damage, Liu Qing,
- ESAs erythropoiesis stimulants
- rHuEPO recombinant erythropoietin
- EPO erythropoietin
- the regulation factor of erythropoiesis in mammals is produced by the kidneys and liver. If the EPO in the blood cannot be raised in the absence of oxygen, it will cause anemia.
- Synthetic expression of EPO regulated by hypoxia-inducible factor (HIF), HIF regulates red blood cells in many processes such as erythrocyte 4, formation, Jin.
- HIF hypoxia-inducible factor
- HIF selectively binds to the hypoxic response element (HRE) of the EPO gene - 1: and then 'j I sends EPO 3 ⁇ 4 due to the transition.
- HRE hypoxic response element
- Flavonoids from radix astragali induce the expression of erythropoietin in cultured cells: a signaling mediated via the accumulation of hypoxia-inducible factor- la, Ken YZ Zheng et al, Journal of Agricultural and Food Chemistry, 201 1 59, 1697- 1704 ".
- ESAs for chemotherapy-induced anemia and renal anemia It is necessary to increase the number of blood transfusions in patients by subcutaneous injection of sputum to increase the red blood cell level of 11 patients. Many clinical trials have injected subcutaneous injections of 5000 IU/day of artificial erythroblastic bovine-causal j to effectively increase red blood cell levels and reduce the number of blood transfusions in patients.
- EPO electronic medical record
- the US Food and Drug Administration (FDA) has issued a number of times; Controls ESAs: Use reports to improve the safety of EASs. Therefore, it is very important to reduce the pain of cancer patients and kidney patients by presenting a drug with low price and small side effects.
- Traditional Chinese medicine has a long history in the treatment of anemia.
- traditional Chinese medicine blood supplement formula usually has no toxic side effects and can be taken for a long time.
- jaundice is often used as a main ingredient for preparation.
- Astragalus membranaceus has been used for more than 2,000 years and has the effect of tonifying blood and producing blood.
- Astragalus saponins contain saponins, sucrose, polysaccharides, various amino acids, folic acid and various trace elements such as selenium, zinc and copper. They have many biological and academic effects, such as liver protection, blood production, anti-oxidation, anti-spasmodic blood pressure, and enhanced immunity.

本发明属于制药领域,具体而言,涉及一种用于促进红细胞生成、 以及预防和治疗贫血和 /或缺氧症的药物组合物或膳食补充用组合物 及 JL:川途。 背景技术
红细胞主耍在人体的骨髓 (bone marrow ) (特别是红骨髓) 内 生成, fj'髓中的千细胞先分化为红细胞原祖细胞, 在促红细胞生成素
( erythropoietin, 也称为红细胞生成索 )的作用 K形成成熟的红细胞。 人体中的促红细胞生成素是由肾脏和肝脏分泌的 -种激素样物质。
贫血 ϋ指人体外周血中红细胞容积的减少,低于正常范围下限的 -种常见的临床症状。 贫血包括化疗诱导性贫血 (CIA ) 和 ^性贫血 等。 中, 在化疗诱导性贫血中, 化疗药物在杀灭大量癌细胞的同吋, 也杀伤了 :ι [ ·:常组织细胞而引起不同程度的 -†髓抑制作用, 因此化疗药 物足通过抑制骨髓造血细胞而引起贫血。超过 60%的癌症病人接受化 疗后都忠有贫血, 严重地降低了病人的机体功能和生活质量。 大多数 化疗药物会引起胃部不适, 造成病人呕吐和恶心, 严重影响食欲并导 致病人体: :减轻, 原困之一就是化疗诱导性贫血 (CIA)。 贤性贫血足 指各种闪素造成肾脏促红细胞生成素产 不足或尿^症血浆中 匕 尜物质 I:扰红细胞的生成和代谢而导致的贫血, 足慢性 ^功能不个 发^到终末期常见的并发症。 病人体内红细胞生成减少、 红细胞 命 缩短以及红细胞丢失增加, 影响病人的血液代谢循环。 通常治疗化疗 诱导性贫血和肾性贫血的方法为输血和透析, ii〖是输血可能会带来严
: 的临床或亚临床副作用, 病人在接受治疗的过程中也会遭受极大的 痛苦。
缺氧 (hypoxia , 或称为缺氧症) 是指因组织的氧气供应不足或 川氧障码, 而导致组织的代谢、 功能和形态结构发生异常变化的病理 过程。 缺氧症 -般表现为: 头暈、 头痛、 耳鸣、 眼花、 四肢软弱无力; 或者产生恶心、 呕吐、 心慌、 气短、 呼吸急促、 心跳快速无力。 红细 胞是脊椎动物体内通过血液运送氧气的最主耍的媒介, 因此增加机体 内红细胞的: ¾可以有效改善缺氧状态 (参见参考文献: "促红素治疗 新^儿缺氧缺血性脑病疗效分析, 郭志梅等, 临床军医杂志, 2008 , 5 " 及 " EPO对新生大鼠缺氧缺血性脑损伤 NSE表达的影响, 刘青,
¾志等, 暨南大学学报: 自然科学与医学版, 201 1, 6 " ) 。
前临床治疗化疗诱导性贫血和肾性贫血以及缺氧症最有效的 药物为红细胞生成刺激物(ESAs ) , 主要为人工重组促红细胞生成素 ( recombinant EPO, rHuEPO ) , 促红细胞生成素 ( EPO ) 足哺乳动物 调节红细胞生成的 要调控因子, 要由肾脏和肝脏产生, 在缺氧状 态下如果无法提升血液中的 EPO含:默将会导致贫血的发生。 EPO 的 合成表达 :耍受缺氧诱导因子 ( HIF ) 的调控, HIF对于红细胞 4·:成、 Jin. \ 生、细胞代谢等多种过程都具有调节作川。在缺氧环境下, HIF 选择性地结合到 EPO基因的低氧响应元件( HRE )― 1:, 进而 'j I发 EPO ¾因的转 · ¾达。 有关可参见参考文献: " Flavonoids from radix astragali induce the expression of erythropoietin in cultured cells: a signaling mediated via the accumulation of hypoxia-inducible factor- l a, Ken Y.Z. Zheng et al, Journal of Agricultural and Food Chemistry, 201 1 , 59, 1697- 1704 " 。
ESAs治疗化疗诱导性贫血和肾性贫血: 要通过皮下注射 ΕΡΟ来 增力 11病人的红细胞水平, 可以有效减少病人的输血次数。 许多临床试 验农明皮下注射剂量为 5000 IU/天的人工 组促红细胞牛-成索 j以有 效的增加红细胞水平并减少病人的输血次数。 「I前 I 1J面― h冇多种基 f i:PO的药物, 美国 Amgen公司(位于美闺加州 Thousand Oaks市)拥有 多项关于 EPO的专利,其产品之 Epogen ® (epoetin alfa)是 1 前被最
广泛使川的 EPO药物。 但是 EPO的应用而临着费用^昂以及严: 副 作川的 题, 如心脏疾病、 血块形成、 高血压、 过敏反应等。 美闺食 药品监 符理局(FDA)多次发布关; 控制 ESAs 剂: 使用的报告来 提^ EASs使用的安全性。 因此幵发一种价格低廉、 毒副作用小的药 物, 对 减轻癌症病人和肾病病人的痛苦具有非常 : 要的 义。
中药应用在贫血治疗上有悠久的历史, 作为纯天然植物药物, 中 药补血配方通常无毒副作用, 可以长期服用。 在用于贫血治疗的中药 补血配方, 经常使用黄芪作为主要成分进行配制。 黄芪的药川迄今已 2000多年的历史, 具有补气生血的功效。 黄芪含皂甙、 蔗糖、 多 糖、 多种氨基酸、 叶酸及硒、 锌、 铜等多种微量元素, 具 许多生物 学和 学功效, 如保肝、 生血、 抗氧化、 抗卨血压、 增强免疫等。 ί ^山于中药的成分复杂, 通常有几十种甚 上 种的化合物组成, 难 以对 进行药理学研究和优化。 中药的药材质量控制也足尤其重要, 产地、 候、 年份等因素都能影响中药材的质量, 从而影响药物的 W 效性和稳定性。 尽管在国内市面上有许多治疗贫血的中药药品, 但是 π治疗效果也足良莠不齐, 因此对中药进行优化, 解决质: ¾:控制等难 题对 f中药的幵发和推广具有重要的意义。
近的研究表明,黄芪中的类黄酮成分能够有效刺激肾细胞中促 红细胞 1 成素的表达, 从而提高血液中的红细胞水平来改善和治疗贫 血。 中^要的四种具有促进促红细胞生成素农达的类黄酮化合物为 刺 柄花素、 芒柄花苷、 毛蕊异黄酮和毛蕊异黄酮 ΐΐ:。 ¾近的研究 明, 儿种从黄芪中分离的类黄酮化合物在单独使川时 I ij以增强细胞低 親反 /、V:兀件 ( HRE ) 的转录活性, 从 lilj促进促红细胞生成素的农达来 提 血液中的红细胞水平 (参见参考文献: " Flavonoids from radix astragali induce the expression of erythropoietin in cultured cells: a signaling mediated via the accumulation of hypoxia-inducible factor- l a. Ken Y.Z. Zheng et al, Journal of Agricultural and Food Chemistry, 201 1 , 59. 1697- 1704 " ) 。 似是「 前的各类黄酮化合物在单独使用时 #在药 效 限— H.使 Π]剂 M较大的缺陷。
