目的 评价杂交捕获Ⅱ代(HC-Ⅱ)与聚合酶链反应(PCR)技术对人乳头状瘤病毒(human papillomavirus,HPV)DNA检测及宫颈高度病变的诊断价值.方法 选取宫颈薄层液基细胞学检查(TCT)异常的200例妇女为研究对象,同时用HC-Ⅱ、导流杂交基因芯片技术(HybriMax)、实时荧光定量PCR法(FQ-PCR)和流式荧光杂交法检测宫颈细胞HPV DNA.以病理组织学检测结果为金标准,比较4种检测方法对宫颈上皮内瘤变(CIN)≥Ⅱ的诊断效果.采用SPSS 13.0软件进行统计学处理.结果 HybriMax、FQ-PCR、流式荧光法和HC-Ⅱ对200例HPV DNA阳性检出率分别为72.5%(145/200)、71.5%(143/200)、70.0%(140/200)和69.0%(138/200).4种HPV DNA检测方法对不同程度宫颈病变的HPV检测阳性率差异无统计学意义(x2=0.252、0134、0.012和0.027,P值均＞0.05),但在诊断CINⅡ及以上病变的敏感度、约登指数和阴性预测值等方面比较差异有统计学意义(x2=7.923、7.819和8.108,P＜0.05).结论 对组织病理学诊断结果为CINⅡ及以上的宫颈病变,HC-Ⅱ的诊断价值优于PCR方法.%Objective To evaluate the application of different assays for detection of human papillomavirus(HPV)in diagnosis of high grade cervical lesions.Methods Two hundred subjects with abnormal thinprep liquid-based cytology test(TCT)Results were selected for HPV DNA detection by hybrid capture 2(HC-Ⅱ) and Methods based on PCR including flow-through hybridization and gene chip (HybriMax),real-time fluorescent quantitative PCR(FQ-PCR)and flow fluorescent hybridization assay.Cytopathological Results were used as gold standards to evaluate the test performance of the above assays for diagnosing cervical intraepithelial neoplasia(CIN)≥Ⅱ. SPSS 13.0 software was used for statistical analysis.Results HPV DNA positive rates of 200 samples by HybriMax,FQ-PCR,flow fluorescent hybridization assay and HC-Ⅱ were 72.5%(145/200),71.5%(143/200),70.0%(140/200)and 69.0%(138/200),respectively,and the differences were not statistically si(g)nificant(x2 =0.252,0134,0.012 and 0.027,P ＞ 0.05).The sensitivity,Youden index and negative predictive value of the above assays were statistically different(x2 =7.923,7.819 and 8.108,P ＜0.05).Conclusion HC-Ⅱ is superior to PCR Methods in diagnosis of CIN Ⅱ and above.
