Abstract:
Purpose To study the infection mode and distribution of high risk human papillomavirus (HR-HPV) in lowgrade squamous intraepithelial lesions (LSILs) and to analysis its effect.Methods HPV genotype of 328 cervical tissues embedded by paraffin which contained 168 LSILs and 160 highgrade squamous intraepithelial lesions (HSILs) were detected by the methods of real-time fluorescence quantitative PCR and in situ hybridization.Results Diseased cells of LSIL stained with hematoxylin and eosin(HE) were concentrated in the upper layer of the cervical squamous epithelium,whereas HSIL were concentrated in the lower layer of the epithelium in HE staining.In LSIL,the positive ratcs of HR-HPV was 95.2％.In LSIL and HSIL,HPV 16/18 positive rates were 26.2％,57.5％,respectively.Other HR-HPV positive rates were 80.9％,55.0％,respectively.The differences were statistically significant (P ＜0.001).HR-HPV positive rate was 70.2％ in the group of in situ hybridization.The positive cells were confined to the surface and middle layer of the LSIL cervical squamous epithelium.Conclusion HR-HPV infection is closely related to LSIL,especially other HR-HPV (except for HPV 16/18).The infection mode of HR-HPV in LSIL starts from the surface layer of the cervical squamous epithelium.
