【摘要】 【目的】探讨采用第二代杂交捕获法(hybrid captureⅡ,HC2)检测高危型人乳头瘤病毒DNA(HPV-DNA)的含量与宫颈癌前病变的关系。【方法】2003年9月至2005年1月就诊于广东省中医院妇科门诊的妇女433例,采用HC2法定量检测其宫颈HPV-DNA的含量,对于阳性患者行膜式薄层液基细胞学(TCT)检查,若细胞学异常,则行阴道镜下宫颈多点活检和宫颈颈管搔刮术。【结果】128例HPV-DNA阳性患者中,细胞学异常者[包括不典型鳞状细胞(ASCUS)、低度鳞状上皮内病变(LSIL)、高度鳞状上皮内病变(HSIL)]为98例(占76.56%),比细胞学为良性反应性细胞(占23.44%)者多,并且细胞学异常者的宫颈组织中的HPV-DNA含量也高于良性反应性细胞者(P<0.05)。对慢性宫颈炎和宫颈上皮内瘤样病变(CIN)者的HPV-DNA含量测定结果显示,两者的HPV-DNA含量无显著性差异(P>0.05),即随着宫颈病变程度的增加,HPV-DNA含量无上升趋势。【结论】HPV-DNA的定性和定量测定对宫颈癌前病变发生的可能性有预测意义,即HPV-DNA阳性并且HPV-DNA含量高者发生宫颈癌的可能性较大,但HPV-DNA的含量测定还不能作为宫颈病变程度的判别指标。更多还原

【Abstract】 【Objective】To explore the relationship of precancerous lesions of uterine cervix with human papillomavirus(HPV)DNA content in high risk women detected by the method of hybrid capture Ⅱ(HC2).【Methods】From September of 2003 to January of 2005,433 outpatients were collected in gynecology department of the Second Affiliated Hospital of Guangzhou University of TCM.Cervical HPV-DNA contents were detected by HC2.For those with HPV-DNA positive,Thinprep cytologic test(TCT)was done and further examination under colposcope such as multiple cervical biopsy and endocervical scraping smear was performed if TCT showed abnormalities of cytology.【Results】There were 128 patients with HPV-DNA positive,and 98(76.56%)with abnormal cytologic changes such as atypical squamous cell of undetermined significance(ASCUS),low-grade squamous intraepithelial lesion(LSIL)and high-grade squamous intraepithelial lesion(HSIL),which was more than those(23.44%)with normal cervical cells.For the patients with abnormalities of cytology,HPV-DNA content was higher than those with normal cervical cells(P<0.05).The HPV-DNA content in patients with chronic cervicitis did not differ from those in patients with cervical intraepithelial neoplasia(CIN),indicating that HPV-DNA content had no increasing tendency when CIN became severe.【Conclusion】Qualitative detection and quantitative detection of HPV-DNA have a predictive value for the occurrence of precancerous lesions of uterine cervix: those with HPV-DNA positive and higher content have a higher risk of cervical neoplasm.However,HPV-DNA content detection cannot be used as the diagnostic criteria of cervical lesion classification.更多还原
