摘要:

分别用原位杂交(ISH)、多聚酶链反应(PCR)和原位多聚酶链反应(IS-PCR)方法,检测39例宫颈鳞状上皮癌石蜡切片中HPV的感染。ISH的检出率为46.2%(17/39),明显低于IS-PCR的66.7%(26/39,P<0.01)和PCR的84.6%(33/39,P<0.01).用常规ISH和地高辛标记探针能检出宫颈鳞状上皮癌HPV16感染的表皮细胞,而用IS-PCR方法在同样标本中可显示出更多的HPV16阳性表皮细胞,并且着色更深。PCR方法敏感性最高,但它不能用于组织细胞内的HPV16DNA精确定位。

Abstract:

In order to compare the sensivity of three methods for the detection of human papillomavirus (HPV)16 DNA, in situ hybridization (ISH), in situ hybridization after amplification by polymerase chain reaction (IS-PCR) and polymerase chain reaction (PCR) were performed in paraffin embedded tissues of 39 cervical squamous intraepithelial lession (SILs). The results showed the detective rate of HPV DNA16 by ISH was 46.2% (17/39).It was lower than 66.7%(26/39) by IS-PCR (P<0.05), and significantly lower than 84.6%(33/39) by PCR (P<0.01). Using conventional ISHwith a dig labbeled probe,variable numbers of superfical cells in SILs showed detectable HPV DNAwhen in situ assay was performed after amplification,increased numders of superfical cells had detectable HPV16 DNA and the signals of hybridization were much more intense.PCR method showed the highest sensitivity,but it failed to show the precise localization of intracellular HPV16 DNA.
