Human papillomavirus (HPV) genotype detection in females aged 18–69 years in Urumqi Saybagh district, China. All subjects underwent gynecological examination and cervical secretion was collected. A genome extraction kit was used for DNA extraction. Polymerase chain reaction (PCR) amplification using the ABI7300 PCR amplification instrument and hybridization were performed. For all the subjects with abnormal liquid-based cytology results, colposcopy and biopsy were performed. The data shown are mean ± standard error of the mean (SEM). (A) HPV infection rates in patients in different age groups. (B) HPV-positive rates in patients with different stages of cervical lesions. Cervical intraepithelial neoplasia (CIN) is a premalignant cervical disease, which includes 3 stages: CIN I, CIN II and CIN III, with increasing disease severity.
