The results showed the expression level of Fas in PBLC of CA was significantly higher than in the normal control group, but the expression level of Bcl 2 was significantly lower (both P< 0.01). The level of IFN γ in serum of CA was significantly lower than in the normal control group ( P< 0.01), but IL 4 was significantly lower (both P< 0.01). The expression of Fas in PBLC had a negative correlation with the level of IFN γ in serum of patients with CA, but had a positive correlation with the level of IL 4; The expression of Bcl 2 had a positive correlation with the level of IFN γ, but had a negative correlation with the level of IL 4. All the correlation coefficients had significant differerce by t test ( P< 0.01). It was suggested abnormal apoptosis in PBLC, the suppressed secretion of the THl associated cytokines (eg: IFN γ) and the increased secretion of the TH2 asssociated cytokines (eg: IL 4) existed in the patients with CA and might play an important role in the immune pathogenesis of CA.展开更多

The results showed that the expression of Fas/FasL in PBLC of the group of short course in CA was significantly higher than that of the normal controls ; the expression of Fas, FasL in PBLC of the group of long course CA was significantly higher than that of the group of short course and the normal controls ( P <0.05 and P <0.01, respectively); the level of IL 2 in serum of the group of short and long course CA was significantly lower than that of the group of normal controls ; the negative relation was revealed between the expression of Fas/FasL in PBLC and the level of IL 2 in serum of patients with CA . It was suggested that the abnormal apoptosis in PBLC and decreased level of IL 2 in serum of CA might play an important role in the course of CA.展开更多

Methods HPVs in CA tissues from 60 patients were detected by immunofluorescence and PCR, respectively. Different subtypes of HPVs were also identified with restriction fragment length polymorphism (RFLP). Results The positive detective rates of immunofluorescence and PCR were 56.67% (34/60) and 96.67% (58/60), respectively (P<0.01). RFLP results showed HPV6 and HPV11 were the main subtypes in the detected virus, which accounted for 98.28%. Conclusion The sensibility of PCR is superior to that of immunofluorescence.展开更多

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

Method: Nd:YAG laser under urethroscope was employed to remove the warts. Result: Seventeen patients out of eighteen cases with CA were cured after the first procedure. The cure rate was 94.4%.For second treatment, the cure rate was 100% and no relapse occurred after observation for 12 - 24 months. Conclusion: Nd:YAG laser by urethroscope is a very good method for the treatment of intraurethral CA.展开更多
