摘要 目的探讨宫颈上皮内瘤变(CIN)病灶内高危型HPV(HR-HPV)与增殖、凋亡基因表达的相关性,为宫颈癌的早期诊断提供理论依据。方法收集2014年5月-2016年12月在天门市第一人民医院经宫颈锥形切除及病理活检确诊为CIN的组织及同期因良性疾病接受子宫全切除术的正常宫颈组织,检测HR-HPV的感染情况及增殖基因、凋亡基因的表达量。结果CINⅠ期、CINⅡ期、CINⅢ期组织中HR-HPV的阳性率显著高于正常宫颈组织,且CIN级别越高,HR-HPV的阳性率越高。CINⅠ期、CINⅡ期、CINⅢ期组织中cyclin B、cyclin D1、cyclin E、MCM7、c FLIP、Survivin、Bcl-2、Livin的mRNA表达量显著高于正常宫颈组织,PTEN、Fas、Fas L、DAPK1、p16INK4A的mRNA表达量显著低于正常宫颈组织,且CIN级别越高,cyclin B、cyclin D1、cyclin E、MCM7、c FLIP、Survivin、Bcl-2、Livin的mRNA表达量越高,PTEN、Fas、Fas L、DAPK1、p16INK4A的mRNA表达量越低。HR-HPV阳性的CIN病灶中cyclin B、cyclin D1、cyclin E、MCM7、c FLIP、Survivin、Bcl-2、Livin的mRNA表达量显著高于HR-HPV阴性的CIN病灶,PTEN、Fas、Fas L、DAPK1、p16INK4A的mRNA表达量显著低于HR-HPV阴性的CIN病灶。结论 CIN病灶内HR-HPV感染能够增加增殖基因及抗凋亡基因的表达、减少促凋亡基因的表达。
