目的:应用PCR-反向点杂交(PCR-reverse dot blot,PCR-RDB)技术对新疆地区人乳头瘤病毒(Human papilloma virus-es,HPV)进行基因分型。方法:收集疑似HPV感染病例标本335例,提取HPV基因组DNA,应用PCR-RDB技术扩增HPV的L1基因并进行分型,计算不同基因型HPV的感染率,组间率的比较采用χ2检验。结果:335例病例标本中检出HPV阳性标本108例,阳性率为32.2%,共检出HPV16、18、33、45、56、68、6、11和66共9种基因型,其中HPV16、18和56亚型的感染较高。分组统计结果显示,HPV阳性率和高危型HPV的检出率在不同类型疾病患者中是不同的,在尖锐湿疣、高度子宫颈上皮内瘤变Ⅱ/Ⅲ和宫颈癌患者中HPV阳性率和高危型HPV的检出率均显著高于宫颈炎组和宫颈糜烂疾病组(P<0.05),而随着年龄的不断增加,HPV感染率降低。HPV的感染率在19~36年龄组较高,随着年龄的增加,HPV感染率有降低趋势。结论:在本地区宫颈病变患者中HPV的感染率较高,而基于PCR-RDB的基因分型可为HPV感染的诊断、治疗和随访提供依据。
Objective:To investigate the genotypes of human papilloma viruses(HPV)in women with different gynecologic diseases in Xinjiang by PCR-reverse dot blot(PCR-RDB). Methods:Clinical specimens from 335 women with suspected symptoms of gynecologic disorders were collected and HPV DNA(L1) was isolated and subjected to genotyping by PCR-RDB. HPV infection rates were cal-culated and statistical analysis of χ2 test was performed to compare the HPV infection rates among different groups. Results:Totally 108 specimens were identified to be HPV positive and the posotive rate was 32.2%(108/335). Nine kinds of HPV genotypes(HPV 16,18,33,45,56,68,6,11,66) were identified by PCR-RDB and HPV 16,18,56 had higher infection rates than other HPV genotypes. Statistic analysis showed that patients with condyloma,cervical intraepithelial neoplasiaⅡ/Ⅲ and cervical cancer had significantly higher HPV positive rates and high-risk HPV infection rates than those with cervicitis or cervical erosion(P<0.05). Additionally,HPV infection rates were decreased with the increasing of age. Conclusions:HPV infection is common in patients with different uter-ine-cervical diseases in Xinjiang and HPV genotyping by PCR-RDB could provide epidemiological evidence for the diagnosis,treat-ment and follow-up of HPV infection.
