Description

通过原癌基因蛋白共振抑制乳腺癌细胞生长的胸罩 技术领域
本发明公开了一种胸罩,属于医疗卫生用品技术和服装领域。
背景技术
据世界卫生组织国际癌症研究中心2013年公布的数据,自2008年以来,全球每年乳腺癌病例以超过20%的速度增长,而死亡率每年增长14%。统计显示,2012年全球有170万妇女被诊断患有乳腺癌,52万人因罹患乳腺癌而死亡。
世界卫生组织预测,到2025年癌症确诊病例将超过1900万例。在中国仅在2015年,新发乳腺癌病例高达26万例,死亡7万例,位居中国女性所有肿瘤发病率之首。
全国肿瘤登记中心发布的《2015年中国肿瘤登记年报》指出,我国登记地区女性乳腺癌发病率为37.86/10万,占女性全部恶性肿瘤发病的17.10%。我国25岁以上年龄段女性乳腺癌发病率迅速上升,在50岁达到高峰。预计到2021年,中国乳腺癌患者人数将高达250万,55岁以上女性中每1000人就可能有一位罹患乳腺癌。
乳腺癌属激素依赖性肿瘤,雌激素在女性乳腺癌的发病中扮演了非常重要的角色。体内的雌激素水平影响乳腺癌的发生、发展,约有2/3的乳腺癌和体内激素水平有关。大量进入乳腺组织的雌激素会在乳腺组织中引起各种反应,其中就包括使乳腺组织增生。最终,就有可能导致乳腺癌的发生。
乳腺癌家族史是乳腺癌发生的危险因素,所谓家族史是指一级亲属中有乳腺癌患者。有研究发现,如果其母亲在绝经前曾患双侧乳腺癌的妇女,自身患乳腺癌的危险性为一般妇女的9倍,而且乳腺癌病人的第二代出现乳腺癌的平均年龄比一般人提早10年左右。姐妹当中有患乳腺癌的女性,其发病危险性为常人的3倍。
女性的一些日常生活习惯也与乳腺癌的发生息息相关,如适当的体育锻炼,少食烟熏、肉类脂肪食物,多摄入蔬菜等可以大大降低乳腺癌的发生。
另外,女性文胸大小不合适或佩戴时间过长会造成组织液、淋巴液流通不畅,影响血液循环,也是增加乳腺癌发病率的一个原因,因此对于女性来说文胸的选择及正确的佩戴很重要。
相对于其他恶性肿瘤,乳腺癌的治疗效果也在逐年提升。根据美国国家癌症研究所的统计,1975年乳腺癌患者的五年存活率只有75.2%,而到了2006年,这个数据已上升到90.6%。也就是说,绝大部分乳腺癌患者在经过正规的治疗(包括手术、内分泌治疗、化疗和放疗)之后,都可以治好,并非像很多人想象的那样,一旦得了癌症,就等于被判了死刑。专家指出,当出现乳房肿块,乳头溢夜,乳房皮肤有“桔样皮”改变,皮肤凹陷出现“酒窝”特征,乳头偏向、内陷等表现时,要及时到医院就诊。
技术问题
目前,乳腺癌的常规诊断方法包括医生临床触诊和影像学诊断,如钼靶X线摄影、B超等,这些检查手段都能起到有效检出早期乳腺癌的作用。但是,这些常规诊断方法,有固有缺陷。它们通常只能检测到直径3mm以上的结节。而一个直径3mm的肿瘤结节中,通常含有10亿个肿瘤细胞。换言之,在肿瘤发生发展达到10亿个细胞以前,现有医学检查技术很难查出来。也就是说,一旦查出来,就是中晚期。虽然有抑制乳腺癌的药物,但依照法律,这些药物都必须在确诊乳腺癌后才能使用,不能对于尚未确诊的乳腺癌患者使用这些药物。那尚未被确诊的10亿个乳腺癌细胞以下的乳腺肿瘤,目前尚无干预和阻断措施。我们需要对肿瘤细胞处于10亿个以前的生长阶段进行有效的干预。
国外学者研究发现,通过电磁波的共振识别模型,在3490nm(85.9THz)是原癌基因蛋白的共振频率,这些计算机定义的致癌基因(f1 = 0.0302)和原癌基因(f2 = 0.0576)蛋白的RRM频率,可以使用比率l= 201 / fRRM转换为所应用照射的实际空间电磁波波长。因此,癌基因激活的计算预测波长为6656nm,原癌基因的计算预测波长为3490nm(ELENA PIROGOVA等.  Investigation of the Structural and Functional Relationships of Oncogene Proteins. PROCEEDINGS OF THE IEEE, VOL. 90, NO. 12, DECEMBER 2002. 1859-1867. )。
本发明的目的就是应用上述的原癌基因蛋白共振抑制乳腺癌细胞的原理,提供一种通过原癌基因蛋白共振抑制乳腺癌细胞生长的应用以及具有预防和治疗乳腺癌作用的胸罩。

最后,本发明提供了一种通过原癌基因蛋白共振抑制乳腺癌细胞生长的胸罩,所述胸罩罩杯的材质由上述组合物制成。
在一个优选的技术方案中, 所述胸罩布料中涂布有含有如下组分的组合物:石墨烯粉、陶瓷粉、珍珠粉。

有益效果
本发明提供了一种抑制早期乳腺癌细胞生长的胸罩,该胸罩包括改性天然乳胶罩杯和特制胸罩贴身布料。罩杯由含有改性天然乳胶的组合物制成,组合物含有天然乳胶、二氧化钛粉、竹碳粉、牡蛎粉,能发射或反射频率为74.9-150THz(波长为2000-4000nm)的电磁波。本发明的研究发现观察改性天然乳胶胸罩处理的MCF—7细胞和MDA—MB—231细胞,可见明显的凋亡形态改变:细胞发泡,染色质聚集,并沿核周呈块状分布,细胞周围可见多个完整膜包裹的凋亡小体。而且随作用时间的延长,凋亡细胞的数量也明显增多,同时出现了坏死的细胞,即细胞肿胀崩解,内容物外泄,细胞形态不规则。改性天然乳胶胸罩三处理的正常乳房上皮细胞株(184B5),并未见明显的凋亡形态改变,仅见坏死的细胞及细胞碎片。天然乳胶胸罩处理的正常乳房上皮细胞株(184B5)、人乳腺癌细胞株MCF—7和MDA—MB—231细胞,也未见明显的凋亡形态改变,未见坏死的细胞及细胞碎片。由于改性天然乳胶胸罩对于正常乳房上皮细胞株生长无影响,因此改性天然乳胶胸罩具有生物安全性。
另外,胸罩贴身布料上,按照乳房乳腺小叶分布和乳房静脉和淋巴分布图,涂布有含有石墨烯粉、陶瓷粉、珍珠粉的组合物,所述组合物能发射或反射频率为15-60THz(波长为5000-20000nm) 的电磁波,能够改善乳房静脉和淋巴循环,同时还作用于乳腺小叶,促进乳房保健。

2.1.1 细胞株:乳房上皮细胞株(184B5)、细胞株雌激素受体阳性(ER+)的人乳腺癌细胞株MCF—7和雌激素受体阴性(ER—)的人乳腺癌细胞株MDA—MB—231,引自北京大学肿瘤医院。
2.1.2 天然乳胶胸罩罩杯制成的胸罩(未添加所述的能反射、发射频率为74.9-150THz电磁波的二氧化钛粉),与改性天然乳胶胸罩罩杯制成的胸罩。
2.1.3 主要仪器 酶标仪为美国伯乐公司生产的2550型酶联仪,流式细胞仪为美国B.D公司FACSC2alibur型。二氧化碳培养箱由上海丙林公司生产。
2.2 方法
2.2.1 细胞培养 乳房上皮细胞株(184B5)、人乳腺癌细胞株MCF—7和MDA—MB—231细胞培养在含10%新生牛血清的RPMI 1640培养基中,置于二氧化碳培养箱内,恒温37℃ ,CO2浓度5%。当细胞长满时,用0.25%胰蛋白酶消化,收集细胞,1000 rpm离心5 min,PBS洗2次,以1×10 4/ml的浓度接种于96孔板内,每孔体积100μl。
使用两个96孔板,每个板均分别培养正常乳房上皮细胞株(184B5)、人乳腺癌细胞株MCF—7和MDA—MB—231细胞各8孔×4排。
2.2.2 将天然乳胶胸罩罩杯制成的胸罩,与不同配方改性天然乳胶胸罩各置于一个细胞培养板下,观察不同细胞培养板中乳房上皮细胞和人乳腺癌细胞的生长情况。
2.2.3 改性天然乳胶胸罩对乳腺癌细胞生长状况的影响(MTT法):连续培养细胞72 h,加MTT溶液,使其终浓度为20 g/L,继续培养4 h后小心吸去培养液。用酶标分析仪测量各孔570nm处的光密度(OD值),以6个孔OD的平均值作为各组的平均OD值。用下列公式计算细胞生长的抑制率。
细胞生长抑制率% =(天然乳胶胸罩组测定的平均OD值一改性天然乳胶胸罩组测定的平均OD值) /天然乳胶胸罩组测定的平均OD值×100。
通过MTT检测得知,天 然乳胶胸罩对正常乳房上皮细胞株(184B5)、人乳腺癌细胞株MCF—7和MDA—MB—231细胞均无抑制作用。
改性天然乳胶胸罩,对MCF—7细胞和MDA—MB—231细胞均有抑制作用,但对正常乳房上皮细胞株(184B5)无抑制作用。

从结果可看出,改性天然乳胶胸罩一可抑制乳腺癌细胞生长,但对正常乳房上皮细胞生长无影响。改性天然乳胶二对乳腺癌细胞生长的影响,与改性天然乳胶一无显著差异。改性天然乳胶三,对乳腺癌细胞的抑制率,显著优于改性天然乳胶一。
2.2.4 细胞形态学观察:
使用两个96孔板,每个板均分别培养正常乳房上皮细胞株(184B5)、人乳腺癌细胞株MCF—7和MDA—MB—231细胞各8孔×4排。将高压灭菌的盖玻片放入12孔板内,以1×10 5/ml细胞浓度接种,每孔500μL。
将天然乳胶胸罩罩杯制成的胸罩,与改性天然乳胶胸罩三各置于一个细胞培养板下。
培养后,分别于24、48和72 h取出盖玻片。甲醇固定10 min,用Giemsa原液与0.01mol/L PBS,按l:10稀释,染色5 min,PBS分色,光镜观察并摄片。
镜下观察改性天然乳胶胸罩三处理的MCF—7细胞(图3)和MDA—MB—231细胞(图4),可见明显的凋亡形态改变:细胞发泡,染色质聚集,并沿核周呈块状分布,细胞周围可见多个完整膜包裹的凋亡小体。而且随作用时间的延长,凋亡细胞的数量也明显增多,同时出现了坏死的细胞,即细胞肿胀崩解,内容物外泄,细胞形态不规则。
改性天然乳胶胸罩三处理的正常乳房上皮细胞株(184B5),并未见明显的凋亡形态改变,仅见坏死的细胞及细胞碎片(图5)。
天然乳胶胸罩处理的正常乳房上皮细胞株(184B5)、人乳腺癌细胞株MCF—7(图6)和MDA—MB—231细胞(图7),也未见明显的凋亡形态改变,未见坏死的细胞及细胞碎片。
由于改性天然乳胶胸罩对于正常乳房上皮细胞株生长无影响,因此,可以初步认为,改性天然乳胶胸罩是生物安全的。
 
实施例3:在胸罩内侧面料上涂印石墨烯粉、陶瓷粉、珍珠粉混合物
3.1 对应于淋巴管、静脉和乳腺小叶,绘制相应的纹路图案(图8)。图8中,A为乳腺小叶投影图、B为乳房静脉淋巴系统投影图,C为A和B组合后的纹路并被绘制在胸罩内侧面料上。
3.2 称取石墨烯粉15克、陶瓷粉50克、珍珠粉35克,混匀,加入用UV胶,搅拌混合,按照所述的纹路图案,涂印于胸罩内侧面料。
3.3 用紫外灯照射,UV胶将石墨烯粉、陶瓷粉、珍珠粉混合物固化粘附在胸罩面料上。
3.4 用傅里叶变换红外光谱仪FTIR检测,确定其能反射、发射频率为15-60THz(波长为5000-20000nm)电磁波(图9中之曲线)。
 
实施例4:涂印石墨烯粉、陶瓷粉、珍珠粉混合物的面料制成的胸罩改善乳房微循环
4.1 使用微循环检测仪,检测安静状态下受试者乳房,可见微循环毛细血管床中,毛细血管输入枝变细,血流缓慢,静脉血回流不良,血流瘀滞。(图10)
4.2 将涂印石墨烯粉、陶瓷粉、珍珠粉混合物的面料制成的胸罩,戴于受试者乳房30分钟,使用使用微循环检测仪,检测受试者乳房的同一部位,可见微循环毛细血输入管床中,毛细血管输入枝扩张,血流加速,静脉回流改善(图11)。
工业实用性
本发明提供的通过原癌基因蛋白共振抑制乳腺癌细胞生长的胸罩具有严格可控的技术参数,可以通过工业化实现规模化生产,具有工业实用性。
