摘要:  摘要: 目的 探讨人乳头状瘤病毒 (HPV) E6/E7 mRNA 检测对高危型人乳头瘤病毒 (HR-HPV) 感染宫颈病变筛查的临床价值。 方法 选择 265 例 HR-HPV 感染者, 其中 100 例病理结果为正常宫颈/慢性炎症 (对照组), 88 例宫颈上皮内瘤变 (CIN) Ⅰ级, 33 例 CINⅡ级, 28 例 CINⅢ级, 16 例宫颈癌患者的宫颈脱落细胞标本, 采用支链 DNA (b- DNA) 技术检测 HPV E6/E7 mRNA 的表达情况。结果 CINⅡ级 (81.82%)、 CINⅢ级 (89.29%)、 宫颈癌组 (100.00%)的 HPV E6/E7 mRNA 阳性率高于对照组 (20.00%) 和 CINⅠ级 (35.23%), 差异有统计学意义, 其余各组间比较差异无统计学意义; CINⅡ级、 CINⅢ级、 宫颈癌组的 HPV E6/E7 mRNA 表达量也高于对照组和 CINⅠ级, 差异有统计学意义, 其余各组间比较差异无统计学意义; 高级别鳞状上皮内瘤变 (HSIL) 和癌组的 HPV E6/E7 mRNA 阳性率及表达量显著高于正常、 非典型鳞状细胞 (ASC) 和低级别鳞状上皮内瘤变 (LSIL) 组 (P < 0.05)。 结论 HPV E6/E7 mRNA 的表达可能提示了病毒的活性和病变的进展程度, 可能成为筛查出高级别宫颈病变的有效指标, 可以作为宫颈癌前病变筛查的辅助方法。

Abstract: Abstract: Objective To explore the clinical value of examining HPV E6 / E7 mRNA level in assessing cervical le⁃ sions infected with high- risk human papillomavirus (HR-HPV). Methods The cervical epithelial cells were collected from 265 patients with HR-HPV infection, including 100 cases of neoplasia free/ inflammation group (control group), 88 cas⁃ es of cervical intraepithelial neoplasia (CIN)Ⅰ, 33 cases of CINⅡ, 28 cases of CINⅢ and 16 cases of cervical carcinoma and the transcription of HPV E6 / E7 mRNA level was examined using branched DNA (b - DNA) technology. Results The positive rate HPV E6/E7 mRNA were higher in CIN Ⅱ (81.82%), CIN Ⅲ(89.29%) and cervical cancer group (100.00%) than tthat in control group (20.00%) and CINⅠ(35.23%) with significant difference, and there were no significant differences between other groups ; The positive rate and transcription level of HPV E6/E7 mRNA in HSIL (high grade squamous intraepi⁃ thelial lesion)and cancer group were significantly higher than normal, ASC(atypical squamous cell carcinoma) and LSIL(low grade squamous intraepithelial lesion) group (P < 0.05). Conclusion The transcription level of HPV E6 / E7 mRNA may re⁃ flect the activity of the virus and the progression of disease, and could be use as an effective indicator to screen high grade cervical pathological changes and a complementary method of cervical lesion screening.
