卵巢早衰和外周血 T 淋巴细胞亚群及补体的关系

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1998
目的: 为明确卵巢早衰者外周血 T 淋巴细胞亚群及补体的特点。方法: 运用免疫酶组化技术———碱性磷酸酶— 抗碱 性磷酸酶( APAAP)法 ,检测卵巢早衰( POF)患者( n =30)、自然绝经后妇女(n=20)及健康育龄妇女( n =30)的外周血 T 淋巴细胞亚群,同时检测其补体水平。结果:①健康育龄妇女、卵巢早衰者及自然绝经者在外周血成熟 T 淋巴细胞总体水平 是一致的。 ②POF 患者及自然绝经后妇女的 CD+ 8 、CD+ 16 T 淋巴细胞数明显升高(P

脐带间充质干细胞源外泌体对子宫内膜基质细胞衰老的影响

open access: yesZhongguo shiyan zhenduanxue
目的探讨脐带间充质干细胞源外泌体对子宫内膜基质细胞衰老的影响机制。方法浓度梯度的米非司酮处理子宫内膜基质细胞后选取适宜浓度诱导细胞衰老。培养脐带间充质干细胞并提取外泌体。米非司酮组、米非司酮与外泌体共处理组分别通过Real-time qPCR检测衰老相关分泌表型mRNA的表达量;流式细胞术检测胞内活性氧含量;β-半乳糖苷酶染色检测细胞衰老情况;Western blot检测衰老相关蛋白表达水平。采用SNK-q检验及Dunnett-t检验分别进行多组间比较和组间比较。结果选用40 μmol ...

人参皂苷Rb1通过Sirt3/SOD2通路延缓高糖诱导的人脐静脉内皮细胞衰老

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2019
【目的】本研究拟探讨人参皂苷Rb1通过调节沉默信息调节因子3/超氧化物歧化酶2(Sirt3/SOD2)通路延缓高糖诱导的人脐静脉内皮细胞(HUVEC)衰老的作用和机制。【方法】建立高糖(40mmol/L葡萄糖)诱导的HUVEC早熟性衰老模型,根据衰老相关β-半乳糖苷酶(SA-β-Gal)阳性率及Ⅰ型纤溶酶原激活物抑制因子(PAI-1)和P16表达评估HUVEC衰老,并采用AnnexinV-FITC/PI排除细胞凋亡的发生。采用Westernblot检测各组Sirt3与SOD2表达的变化 ...

端粒和端粒酶在临床肿瘤诊断中的应用 [PDF]

open access: yes, 1998
现代肿瘤学研究认为肿瘤是多种癌基因突变、扩增或抑癌基因突变或失活累积的结果;按实验肿瘤发生的性质可分为启动、促进和演进3个不同而又相关的过程。不同组织类型肿瘤的癌基因和抑癌基因变化尚无统一的变化规律。端粒酶(TElOMErASE)在绝大多数恶性肿瘤都..
