ABSTRACT
Objective To investigate the distribution of 39 kinds of human papillomavirus(HPV)infection genotypes in female cervical cells and its clinical significance.Methods 39 types of HPV DNA were extracted from 434 samples of female cervical cells. The gene amplification combined with the gene chip technique was adopted to detect 39 kinds of HPV genotype.And the clinical da-ta of the patients were analyzed.Results Among 434 samples of female cervical cell,175 cases were HPV positive,the total HPV infection rate was 40.32%(175/434).Among them,105 cases were the single type HPV infection with the positive detection rate of 24.19%(105/434)and 70 cases were the multiple types HPV infection with the positive detection rate of 16.13%(70/434).Among single type HPV infection,31 cases were the HPV18 infection with the positive detection rate of 17.71%(31/175),which was the main HPV infection type;followed by HPV16 in 12 cases with the positive detection rate of 6.86%(12/175)and HPV52 in 11 cases with the positive detection rate of 6.29%(11/175).Among the multi-type HPV infection,each 2 cases were HPV 6+54,HPV 18+52,HPV 51+68 infection respectively,each accounted for 2.86% of the multi-type HPV infection,which were the main infection types.Conclusion HPV 16,18,52 and HPV 6+54,HPV 18 +52 and HPV 51 +68 are the main HPV infection genotypes of fe-male cervical cells.The gene amplification combined with the gene chips technique is a method suitable for clinically conducting the HPV genotyping diagnosis and the molecular epidemiologic research of HPV infection.Along with the increase of detected HPV genotypes,the HPV infection rate is also increased,its genotypes combinations trend towards diversification.
