Objective To investigate the prevalence of cervical human papillomavirus (HPV)infection in women with and without cervical lesions in Zhejiang province.Methods Cervical exfoliated cell samples were collected in 865 women with cervical lesions and 630 women with normal cytology from Zhejiang Provincial People's Hospital,Red Cross Hospital of Hangzhou,Maternal and Child Health Hospital of Fuyang City,and the Department of Basic Medical Sciences of Zhejiang Medical College of Zhejiang province.The flow-through hybridization technique (HybriMax) was used to detect 21 kinds of HPV genotypes.x2 and exact test were used for the comparison of HPV infection rates and genotype distributions between women with cervical lesions and those with normal cytology.Results The prevalenceof HPV infection in women with cervical lesions (27.28％,236/865) was significantly higher than that in women with normal cytology (10.32％,65/630) (x2 =65.2,P ＜0.01).In cervical lesion group,60 out of 236 HPV-positive patients (25.42％) were infected with multiple HPVs,including 42 patients infected with 2 genotypes of HPV,12 with 3 types of HPV,5 with 4 types of HPV and 1 with 5 types of HPV ; while in HPV-positive women with normal cytology,only 1 case was infected with multiple HPVs,with a rate of 1.54％ (1/65) (x2 =18.0,P ＜ 0.01).Totally 321 strains (covering 19 HPV genotypes) of HPV were obtained in cervical lesion group,including 188 (58.57％) strains of high-risk,114 (35.51％) strains of low-risk,and 19 (5.92％) strains of other types,and the most prevalent high-risk genotypes were HPV-16,HPV-58,HPV-33,HPV-52 and HPV-39.While in normal cytology group,66 strains (covering 16 HPV genotypes) of HPV were obtained,and the most prevalent genotypes were HPV-52,HPV-16,HPV-31,HPV-58 and HPV-ep8304.Conclusion The prevalence of HPV infection in women with cervical lesions is significantly higher than that in women with normal cytology,and the most prevalent genotypes of infection are HPV-16,HPV-58,HPV-33,HPV-52 and HPV-39.%目的 分析浙江省宫颈病变及宫颈细胞学正常的妇女宫颈人乳头瘤病毒(HPV)感染率及其基因型分布特点.方法 收集2010年1月至2012年12月在浙江省人民医院、杭州市红十字会医院、浙江省富阳市妇幼保健院和浙江医学高等专科学校基础医学部的经液基细胞学检查诊断为宫颈病变患者865例(宫颈病变组),并选择经液基细胞学检查宫颈细胞学正常的630名同期体检者为健康对照.采用导流杂交基因芯片技术(HybriMax)对所有研究对象进行21种HPV基因型分型检测,并采用x2检验或确切概率法比较两组HPV感染率及其21种基因型的检出情况.结果 宫颈病变组检出HPV阳性236例,阳性率为27.28％,健康对照组检出HPV阳性65例,阳性率为10.32％,二组HPV阳性率比较差异有统计学意义(x2=65.2,P＜0.01)).宫颈病变组HPV基因不同型别重叠感染60例,其中双重感染42例,三重、四重和五重感染分别有12例,5例和1例,重叠感染率为25.42％ (60/236)；健康对照组HPV重叠感染仅1例,重叠感染率为1.54％(1/65),二组重叠感染率比较差异有统计学意义(x2=18.0,P＜0.01).宫颈病变组共检测到321株HPV病毒株,19种HPV基因型,高危型、低危型和其他类型HPV分别占58.57％(188/321),35.51％(114/321)和5.92％(19/321),其中高危型HPV基因型检出率居前5位的分别为HPV-16,HPV-58,HPV-33,HPV-52和HPV-39；健康对照组共检出66株HPV病毒株,16种HPV基因型,检出率居前5位的分别为HPV-52,HPV-16,HPV-31,HPV-58和HPV-ep8304.结论 本地区宫颈病变妇女HPV感染率及重叠感染率明显高于宫颈细胞学正常的妇女,且以HPV-16,HPV-58,HPV-33,HPV-52和HPV-39等高危型HPV感染为主.
