ABSTRACT
Objective To study cervical human papillomavirus (HPV) infection and genotype distribution characteristics in patients with vaginal disease.Methods The PCR dot blot was used to carry out HPV detection of cervical exfoliated cells in 816 women with cervical lesions in the hospital, and 23 kinds of HPV genotypes were identified.Results Among the 816 cases receiving HPV type detection, HPV of 532 cases (65.20%) was positive, including 371 cases (69.74%) with low-risk HPV (HR-HPV) infection, 161 cases (30.26%) with low-risk HPV infection (LR-HPV) (P<0.05).The HPV infection rate below 45 years old was relatively higher.The HPV infection rate in patients with cervical cancer (97.10%) was higher than that in patients with cervical intraepithelial neoplasia (CIN) II -III (80.54%), patients with CIN Ⅰ(41.55%) and patients with cervicitis (17.20%) (P<0.05).The top five types of HPV infection were HPV16, 58, 18, 11 and 56 type, respectively.The single infection rate (79.70%) was higher than multiple infection rate (20.30%) (P<0.05); HR-HPV infection was the main infection in single infection, and double infection was the main infection in multiple infection.Conclusion Below 45 years old women are the high-risk groups of HPV infection.16, 58, 18, 11 and 56 are the main types of HPV infection.The infection rates of patients with cervical cancer and precancerous lesions are relatively higher.Paying attention to the screening of HPV infection has positive significance in the prevention and treatment of cervical cancer.
