2、术检测蜕膜组织和外周血CD3和CD4T细胞中ICOS的表达;Real—TimePCR检测蜕膜组织中ICOSmRNA的表达情况。结果URSA组蜕膜组织中ICOSCD3T淋巴细胞亚群所占百分比为(0.612±0.693)%,显著高于正常对照组的(0.0564-0.103)%,差异有统计学意义(P<0.001)。URSA组外周血ICOSCD4T淋巴细胞亚群所占百分比为(1.9434-0.762)%,显著高于正常对照组的(0.221±0.127)%,差异有统计学意义(P<0.001)。URSA组蜕膜组织中ICOSmRNA的相对表达量较正常对照组显著升高[(9.875±1.464
3、)US(2.701±1.737)],差异有统计学意义(P<0.05)。结论蜕膜组织中ICOS的表达异常与URSA的发病具有密切关系。[关键词]诱导性共刺激分子;原因不明复发性流产;蜕膜;外周血[DOI]10.3969/j.issn.1674-8115.2012.05.024[中图分类号]R714.21[文献标志码]AResearchonrelationshipbetweenexpressionofinducibleco-stimulatorandunexplainedrecurrentspontaneousabortionWEIJia.ZHAOAi—minfDepart
