摘    要:目的研究脆性组胺三联体(fragile histidine triad,FHIT)蛋白和增殖细胞核抗原(proliferating cell nuclear antigen,PCNA)蛋白在宫颈涂片中的表达及在宫颈癌前病变诊断中的意义。方法选取2004年6月至2005年6月在兰州大学第一医院妇科门诊宫颈计算机辅助细胞学检测涂片(computer—assisted cytology test,CCT)为低度鳞状上皮内病变(low-grade squamous intraepithelial lesion,LSIL)(74例)和高度鳞状上皮内病变(high—grade squamous intraepithelial lesion,HSIL)(40例)的可疑宫颈病变患者114例,采用免疫组化法检测患者宫颈组织中脆性组胺三联体、增殖细胞核抗原蛋白的表达情况。结果脆性组胺三联体蛋白在正常宫颈上皮中表达,在宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)及宫颈癌中表达缺失,在宫颈上皮内瘤变Ⅰ、宫颈上皮内瘤变Ⅱ、宫颈上皮内瘤变Ⅲ及宫颈癌组织中,其表达缺失率分别为13.3%,30.0%,60.0%和71.4%。增殖细胞核抗原蛋白在宫颈上皮内瘤变及宫颈癌中表达升高,在宫颈上皮内瘤变Ⅰ、宫颈上皮内瘤变Ⅱ、宫颈上皮内瘤变Ⅲ及宫颈癌组织中,其阳性表达率分别为44.7%,60.0%.80.0%,85.7%,而且其染色强度明显升高。各组间脆性组胺三联体蛋白、增殖细胞核抗原蛋白表达率比较,差异有显著意义(P=0.0001)。结论脆性组胺三联体蛋白表达缺失,是宫颈癌发生的早期事件,其表达缺失程度与宫颈上皮内瘤变的分级有关,高级别的癌前病变缺失率明显增高;增殖细胞核抗原蛋白的表达,在宫颈癌前病变中逐级增高,可用于评估癌前病变的恶变潜能。

关 键 词:宫颈刮片  宫颈上皮内瘤变  宫颈癌  脆性组胺三联体  增殖细胞核抗原
