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 CINⅢand 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%), CINⅢ(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.
