This study is to investigate the cervical human papillomavirus (HPV) infection rate in women of Urumqi, China.The epidemiological questionnaire survey was used to study 2300 women in Urumqi with a prospective research method. The second-generation hybrid capture assay, cervical liquid-based cytology test, colposcopy, and cervical biopsy were used to screen CC.In 2300 cases, HPV was detected in 385 cases with infection rate of 16.74%. The infection rates of Uygur and Han women were 20.08% and 13.39%, respectively, with significant differences (P <.05). Among all age groups, the infection rate was highest in the age group of 20 to 25 years (with infection rate of 22.22%), followed by the age group of 45 to 49 years (with infection rate of 18.78%). In 8 districts, the highest positive rate was in Saybagh District with infection rate of 24.79%, followed by Urumqi County with infection rate of 19.05%, and the lowest was in Toutunhe District with infection rate of 10.86%. There was no significant difference in HPV infection among all age groups or among 8 districts of Urumqi. HPV infection rates were 10.48%, 84.52%, 92.94%, 100% in chronic cervicitis, low grade and high-grade intraepithelial neoplasia and CC group, respectively. The difference was statistically significant (P <.05).The HPV infection rate of Uygur is higher than that in Han ethnic in Urumqi. The infection rate of HPV increases with the severity of cervical lesions.
Objective: Patients whose cervical cytological exams produced a result of atypical squamous cells of undetermined significance (ASCUS) were asked to undergo human papillomavirus (HPV DNA) genotyping detection to assess the role of HPV infection in ASCUS. Materials and Methods: This study included 1,219 patients with ASCUS that were randomly divided into two groups. The first group contained 618 patients. These participants underwent colposcopy with cervical biopsy. The remaining 601 underwent colposcopy and biopsy with HPV DNA detection. Results: Out of the 56,000 patients with ASCUS who underwent ThinPrep cytology test (TCT) detection in the authors' hospitals' gynecological outpatient clinics, 1,604 were diagnosed with ASCUS (2.86%). Among the 1,219 patients with ASCUS, the rate of detection of cervical intraepithelial neoplasia (CIN) and cancerization was 22.89% (279/1,219). Among the 601 patients who underwent HPV testing, 182 were positive for high-risk HPV (30.28%). Among HPV-positive samples, the most common high-risk types were HPV16, and HPV58. The most common low-risk types were HPV6 and HPV11. The rate of detection among highrisk patients who were positive for HPV and cervical carcinoma with intraepithelial neoplasia was 70.88% (129/182). The rate of detection for HPV-negative patients with cervical cancer with intraepithelial neoplasia was 11.55% (47/407). The rate of detection of high-risk HPV was higher than among patients who had not undergone HPV detection and among patients who were negative for HPV (p < 0.05). Conclusion: The results of cervical cytological examination showed that the manner of progression from inflammation to cancer could differ considerably. HPV DNA examination is an effective means of categorizing and managing ASCUS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
