RESUMO
Objective To contrast HPV genotyping and clinical characteristics of women in Yan'an and provide data support for cervical cancer screening and prevention.Methods The genotyping of HPV infection was carried out by the method of PCR amplification and reverse hybridization.To statistical analysis clinical infection distribution data.Results Found 16.48％ (332 of 2014) were positive for HPV DNA in these women.HPV-16,52 and 53 were in the top three HPV high-risk types.HPV-81,6 and 44 were in the top three HPV low-risk types.There were 219 cases (65.96％) with pure high-risk type infection,74 cases (22.29％) with pure low-risk type infection and 39 cases (11.75％) with mixed infection in positive specimens.The HPV infection rate had showed first increasing then decreasing with age,and there were significant differences among the each groups (x2=34.238,P＜0.01).There were also differences in HPV positive detection rates in different occupations and there were significant differences among the each groups (x2=50.35,P＜0.01).There were also differences in HPV positive detection rates in different regions,and there were significant differences among the each groups (x2 =12.084,P＜0.05).Single infection was highest in HPV infection.Conclusion HPV infection was different in different populations,regions and ages,and it is of great significance to carry out HPV screening for early prevention and treatment of cervical cancer.
