Abstract: Objective To explore the genotype and distribution of humam papilloma viruses among cervical erosion patients,and to guide the preventing and treat ing cancer of uterine cervix.Methods T he cervical erosion specimens were collected and divided into two groups,the CA group and no-CA group.The immunohistochemistry assay and PCR technique were used to detect the genotypes of HPV-DNA.Results The 76 cases(67.8%)in CA g roup and the 163 cases(47.7%) in no-CA group were confirmed to be HPV-DNA positive.T he positive rates of HPV were Ⅰ° 55.5%,Ⅱ° 64.7% and Ⅲ° 83.3% in CA group;and Ⅰ° 32.8%,Ⅱ° 49.6% and Ⅲ° 62.3% in non-CA group among cervical erosion patients respectively.The genotype of HPV-DNA was 6,11,16,18,58,45 and 33.Conclusion T here is hig her incidence of HPV among cerv ical erosion pat ients in the region,and the incidence of HPV has a positive association ith the cervical erosion deg rees.It is of paramount importance to control HPV infection and treat cervical erosion effectively for preventing and treating cancer of uterine cervix.
