Methods: Assaying the expression of telomerase and thetype of HPV in damaged skin of 42 CA patients and normalskin of 30 healthy control individuals through telomeraserepeat amplification protocol (TRAP) and polymerase chainreaction (PCR). Results: In all the normal skin controls, PCR for HPV wasnegative and only 16.7% of samples were positive for TLMAexpression; in CA lesions, HPV testing was positive in all (32cases were low-risk, 3 were high-risk, and 7 were of mixedtype) and all were positive for TLMA expression. Conclusion: TLMA may be activated by HPV infection,and in turn cause the hyperplasia of epidermal cells. It wasalso indicated that HPV, especially high risk types, canactivate TLMA. The activation of TLMA may play animportant role in abnormal hyperplasia and carcinomatouschanges in CA lesions.展开更多
This study investigated the relationship between human papillomavirus (HPV) genotype and expression of p53and p21^(WAF1) Expression of p53 and p2l^(WAF1) in 35 cases ofcondyloma acuminatum specimens infected by HPV6/1...This study investigated the relationship between human papillomavirus (HPV) genotype and expression of p53and p21^(WAF1) Expression of p53 and p2l^(WAF1) in 35 cases ofcondyloma acuminatum specimens infected by HPV6/11andHPV16/18 were studied using immunohistochemical staining.All specimens of the condyloma acuminatum case were positivefor expression of p53 and p21^(WAF1). The expression of p53 incondyloma acuminatum infected by HPV16/18 wassignificantly lower than that in specimens infected byHPV6/11.However, expression of p21^(WAF1) between the twogroups was not significantly different. Expression of p53 incondyloma acuminatum is likely related to HPV genotype,exoression of p21^(WAF1) was not related to HPV genotype.展开更多

Methods: Specimens of CA-DNA quantification from 94cases were examined by real time FQ-PCR technique and 32cases were compared with the same method after 10-daystreatment. Results: CA-DNA was found in all patients, with an averageof 4.0×10^6 copies/ul. After 10 days of treatment, the averagewas 2.1×10^5 copies/ul. There was a significant difference inthe average amount of CA-DNA before and after thetreatment. Conclusion: Real time FQ-PCR is a good method forexamining CA-DNA amount and it can direct the treatment of CA.展开更多
