宫颈正常细胞和不典型鳞状细胞中人乳头瘤病毒感染型别分布的分析

Analysis of HPV infection types distribution in normal cells and ASC-US in uterine cervix

目的分析女性宫颈正常细胞和不典型鳞状细胞(ASC-US)中人乳头瘤病毒(HPV)感染基因型分布及其临床意义,同时对ASC-US患者行宫颈病理组织学诊断分析。方法 1 000例宫颈细胞学检查结果为正常的女性纳入对照组;宫颈细胞学诊断为ASC-US的女性236例纳入ASC-US组,所有研究对象均提取23种HPV-DNA,采用基因扩增结合基因芯片技术进行基因分型检测,所有ASC-US患者行宫颈活检病理组织学诊断,并对受检者进行相关资料分析。结果对照组中检出HPV感染者106例,总的HPV感染率为10.6%,其中1型感染率为9.3%,多型感染率为1.3%;ASC-US组中检出HPV感染者139例,总的HPV感染率为58.9%,其中1型感染率为38.1%,多型感染率为20.8%。对照组与ASC-US组HPV总感染率、1型感染率和多型感染率比较,差异均有统计学意义(P<0.05)。对照组中构成比居前6位的型别依次是HPV43、16、58、33、52、18、42型,ASC-US组中构成比居前6位的型别依次是HPV16、18、52、58、33、51、66型。结论基因芯片检测技术可用于宫颈细胞HPV分型检测,对宫颈ASC-US的进一步分流管理具有重要临床的意义,应引起妇科医师的高度关注。

Objective To explore the clinical distribution and significant of 23 kinds of human papillomavirus(HPV)genetypes in normal cells and atypical squamous cells(ASC-US),meanwhile analysis result of cervical histological pathology diagnosis in cases of ASC-US.Methods A total of 1 000 women with normal cells specimens were recruited into control group,and 236 women with ASC-US were selected into the ASC-US group.Polymerase chain reaction(PCR)and gene-chips technology were utilized for the detection of 23 kinds of HPV genetypes,all cases of ASC-US diagnosis of cervical pathological histology.Results A total of 106 cases of HPV infection were detected in the control group,as the total HPV infection rate was 10.6%,in which the single genotypes infection rate was 9.3%and the multiple genotypes infection rate was 1.3%.A total of 139 cases of HPV infection were detected in ASC-US group,as the total HPV infection rate was 58.9%,in which the single genotypes infection rate was 38.1%,and the multiple genotypes infection rate was 20.8%.There were significant differences on the total HPV infection rate,the infection rates of type 1 and multiple geontypes between the control group and ASC-US group(P<0.05).The top six of constituent ratio in the control group were type 43,16,58,33,52,18,42,those in the ASC-US group were type 16,18,52,58,33,51,66.Conclusion PCR combined with the gene-chip technology could be used in the HPV genotypes detection in cervical cells,which has important clinical significance on the further distribution management of ASC-US,and should be draw great attention.
