摘要 目的探讨宫颈脱落细胞中人端粒酶逆转录酶催化蛋白亚单位信使RNA(h TERT mRNA)的表达在宫颈疾病诊断中的作用。方法应用RT-PCR法检测宫颈鳞状细胞癌(SCC)、宫颈上皮内瘤样病变(CIN)Ⅱ~Ⅲ、CINⅠ、慢性宫颈炎和正常子宫颈的宫颈脱落细胞中h TERT mRNA表达情况,对各组h TERT mRNA阳性率进行统计分析。结果在各种宫颈疾病病例中,宫颈脱落细胞h TERT mRNA的阳性率依次为SCC(94.9%)〉CINⅡ~Ⅲ(70.1%)〉CINⅠ(46.7%)〉慢性宫颈炎(7.1%)和正常子宫颈(5.0%)(P〈0.01)。慢性宫颈炎与正常子宫颈比较,h TERT mRNA阳性率差异无统计学意义;在SCC和CIN各级病变中,h TERT mRNA阳性率与组织病理学级别的升高存在密切关系。结论宫颈脱落细胞h TERT mRNA可作为宫颈疾病进展的早期预警指标。
