1、健康大视野2014年8月第22卷第8期HealthHorizon,August2014,Vo1.22No.8论著CD4+CD25+调节性T细胞与2型糖尿病胰岛素抵抗的相关性研究王纯明吴继辉陈永生枣庄市峄城区人民医院(山东枣庄2773o0)山东省枣庄电业局医院山东省临沂市人民医院【摘要】目的研究2型糖尿病患者CD4CD25调节性T细胞与胰岛素抵抗(IR)之间的相关性及其意义,以期为减少2型糖尿病患者胰岛功能损害和糖尿病慢性并发症的发生提供理论依据。方法用流式细胞仪检测2型糖尿病患者治疗前以;zLf_常对
2、照组血液CD3、CD4、CD8、CD25调节性T细胞;血糖采用葡萄糖氧化酶法;胰岛素、胰岛素抗体采用放射免疫分析法(RIA)。并探讨血糖、胰岛素、胰岛素抗体与CD4CD25调节性T细胞之间的相关性。稳态模型评估法计算胰岛素抵抗指数(HOMA.IR)=空腹胰岛素×空腹血糖/22.5。结果2型糖尿病患者外周血淋巴细胞CD25、CD4和CD4~/CD8比值明显低于对照组,CD8高于对照组;CD3CD25、CD4CD25和CD4CD25~/CD8CD25显著降低(P<0.01)。血糖、胰岛素抗体明显高于对照组
