The HPV positivity amongst the group of women with no cervical abnormality was 43%, while that in women with cervical dysplasia and cervical cancer was 81.2% PCR products from 89 HPV positive cases were genotyped by LiPA, of which 49 cases were single HPV infected concerning 11 different HPV types and the commonest type was HPV-16, occurring in 25(51%) of all single HPV infected cases. The other 40 specimens contained multiple HPV types comprising 16 different HPV types. Although double infections(n=25) prevailed, triple(n=9),quadruple(n=3) and quintuple(n=3) infections were also found. PCR products of four HPV positive cases failed to be classified by LiPA. Sequencing analysis revealed that these 4 cases were HPV-66 which was not included in LiPA probes. Follow-up data of 12 cases confirmed the HPV genotyping results. Conclusion The LiPA for HPV genotyping is easy to perform.

结果 155例妇女子宫颈刮片中HPV DNA检出率为60%，其中在宫颈细胞学检查正常或仅有炎症病变的妇女中HPV DNA阳性率为43%，而在宫颈细胞增生不良或宫颈细胞癌的妇女其阳性率为81.2%。93例HPV阳性的标本中，89例利用LiPA成功地作出了基因分型，其中单独一型HPV感染为49例，涉及11种不同基因型HPV，最常见的型别为HPV 16，占单独感染的51%(25/49)；另40例为不同型别HPV重叠感染，涉及所有16种HPV基因型别，二重感染占主导地位(n=25)，同时也检测出其它多重感染。4例HPV阳性的标本应用LiPA未能作出基因分型，DNA序列分析显示这4例为HPV 66感染，此型别不包括在LiPA所标记的探针内。12例随诊资料显示了LiPA的物异性及高度的重复性。
