Abstract:
Objective To investigate the efficiency of three methods to detect HPV infection of desquamated cervical epithelial cells and the relationship between methods and TCT.Methods hC2 method was used in disconnecting the HPV DNA chain in the samples to hybrid captures,and examine the 13 types of HPV which were highly related to cervical carcinoma.Q-PCR was first used to extract HPV DNA of samples and expanded nucleotide to be examined on Q-PCR to obtain results directly.MPHC was used to extract HPV DNA and to amplify nucleotide.The products was added to micro-well plate to proceed hybridization,and enzyme label was added,and results were studied in the enzyme labelling apparatus.The results of the latter two methods were the same as hC2.hC2 matched Q-PCR was used to examine 260 eases of desquamated cells from HPV infection against 200 cases of desquamated cells from HPV infection,and the results were compared by using MPHC matching examination.Results 1.With three methods,HPV infection was found to be 100% in all the abnormal cervical squamous epithelial cells.2.The sensitivity of the methods,howerer,was different.The QFCR and MPHC had higher positive rate than hC2.Positive HPV infection rate with Q-PCR and MPHC was the same as that of hC2 in the majority of cases,as in a few cases,it was positive with Q-PCR and MPHC but negative with hC2 alone False positive rate was 2% in MPHC.Conclusion HPV testing combined with the TCT routine is the best screening program for detecting cervical cancer and precursor of cervical careinoma.
