摘要
采用荧光偏振人乳头瘤病毒 (humanpapillomavirus,HPV )分型新方法探讨了 8种常见型别HPV在陕西宫颈癌患者中的流行情况。首先 ,用HPVGP5 +/GP6 +通用引物PCR扩增 6 5例早期宫颈癌 (Ⅱa期内 )和 72例慢性宫颈炎病变组织DNA粗提物 ,继之将模板指导的末端延伸反应与荧光偏振检测技术结合 (TDI FP) ,用GP5 +/GP6 +扩增区内的HPV 6、1 1、1 6、1 8、31、33、35和 5 8型特异性探针与PCR产物杂交后 ,荧光素标记的特异碱基 (TAMRA ddTTP或R1 1 0 ddGTP)在GP5 +/GP6 +产物中相应的模板指导下 ,掺入延伸至相应探针末端 ,致使对应的TAMRA或R1 1 0FP值升高 ,从而对扩增的HPV阳性产物进行HPV分型。6 5例宫颈癌患者中检出HPV 5 7例 ,阳性率 87.6 9% ,72例慢性宫颈炎患者中检出HPV 2 8例 ,阳性率 38.89% ,两组间HPV阳性率有显著性差异。宫颈癌与慢性宫颈炎患者中 4种最常见的HPV型别分别是HPV 1 6(4 5 .6 % )、HPV 1 8(2 2 .8% )、HPV 5 8(1 7.5 % )、HPV 31 (7.0 2 % )和HPV 1 6 (35 .7% )、HPV 1 1 (32 .1 % )、HPV 6 (2 1 .4 % )、HPV 1 8(1 0 .7% )。慢性宫颈炎患者中检出的HPV型别 5 7.1 4 %属高危型。HPV 1 6在两组中均最为多见。中国陕西宫颈疾病患者中HPV感染有其特点 ,世界范围内少见的HPV 5 8在陕西宫颈癌
