Abstract

Objective To compare the genotypes distribution of human papillomavirus (HPV ) infection in tissues of cervical cancers and cervical intraepithelial neoplasias (CIN ) and its clinical significance .Methods The polymerase chain reaction (PCR) and the gene-chips technique were utilized for the detection of 23 kinds of HPV genotypes in the tissue specimens from 192 cases of cervical intraepithelial neoplasia (CIN) and 85 cases of cervical cancers .And the related data of all subjects were analyzed .Results In 192 cases of CIN ,the total positive rate of HPV was 82 .29% (158/192) ,the positive rate of single genotype infection was 46 .88% (90/192) and the positive rate of multiple genotypes infection was 35 .42% (68/192);In 85 cases of cervical cancers ,the to-tal infection rate of HPV was 88 .24% (75/85) ,the positive rate of single genotype infection was 65 .88% (56/85) and the positive rate of multiple genotypes infection was 22 .35% (19/85) .Conclusion PCR combined with the gene-chips technique can be used in the detection of the tissue samples of cervical lesions ,once detection can detect 23 kinds of HPV genotypes with high sensitivity and strong specificity ,which has very important significance to the prevention and treatment of cervical cancer and precancerous lesions and the their vaccine research .
