Objective To evaluate the effects of acitretin combined with clarithromycin on tumor growth in human oral epidermoid carcinoma xenografts in nude mice,and to investigate their antitumor mechanisms.Methods A cell line of human oral epidermoid carcinoma was subcutaneously inoculated into 31 Balb/c nude mice to establish a xenograft model of human skin tumor.Then,the nude mice were randomly classified into 6 groups according to a double blind protocol:control group (n =6) remaining untreated,placebo group (n =5) treated with wheat flour,acitretin group (n =5) treated with acitretin 7.2 mg/kg per day,clarithromycin group (n =5) treated with clarithromycin 100 mg/kg per day,acitretin + placebo group (n =5) treated with both acitretin (7.2 mg/kg per day) and wheat flour,and acitretin + clarithromycin group (n =5) treated with acitretin (7.2 mg/kg per day) and clarithromycin 100 mg/kg per day.All the drugs were intragastrically administrated once daily.After three weeks of treatment,mice were sacrificed and xenografts were removed.Then,the size and weight of xenografts were measured,and pathological analysis was conducted.Real time-PCR was performed to quantify the mRNA expressions of vascular endothelial growth factor (VEGF) and nuclear factor (NF)-κB,and immunohistochemistry was carried out to observe the expression of VEGF as well as to determine microvessel density (MVD) and Ki-67 proliferation index.By using the software SPSS 19.0,analysis of variance was performed for comparison of measurement data,and least significant difference (LSD) test for paired comparisons.Results Both the size and weight of xenografts in the acitretin + clarithromycin group were significantly lower than those in the other groups (all P ＜ 0.05).Real-time fluorescence-based PCR revealed weaker mRNA expressions of VEGF and NF-κB in the acitretin + clarithromycin group compared with the control group,clarithromycin group and acitretin group (all P ＜ 0.05).As immunohistochemistry showed,the acitretin + clarithromycin group displayed a decrease in the expression rate (all P ＜ 0.01) and staining intensity of VEGF,MVD (all P ＜ 0.01) with a sparse distribution of microvessels,Ki-67 proliferation index (all P ＜ 0.05) and proliferative activity of tumor cells compared with the control group,clarithromycin group and acitretin group.Conclusion Acitretin combined with clarithromycin can synergistically inhibit the growth of human oral epidermoid carcinoma xenografts in nude mice,downregulate VEGF expression,and suppress angiogenesis and tumor proliferation.

Objective To report the surgical approach for the treatment of giant or extensive skin lesions due to the infection of human papilloma virus (HPV). Method Surgical treatment was performed for 10 patients with verruca vulgris, 20 with condyloma acuminatum, and 8 with epidermodyplasia verruciformis, whose giant or extensive lesions were poorly responsive to routine non-surgical therapy. Results Recurrence of lesions was found in 2 of 10 patients with verruca vulgris and 5 of 20 condyloma acuminatum in 6 months after operation, with a total recurrent rate of 25%. The extensive skin lesions were removed and the functions of affected limbs were recovered in patients with epidermodyplasia verruciformis after operation, however, the long-term topical retinoids was needed to control the recurrence of the lesions. Conclusion Surgical approach is effective for the treatment of the giant or extensive skin lesions due to HPV infection.

Objective: To study the impact of interferon-inducible protein 16 (IFI16) inhibition on apoptosis of human aortic adventitial fibroblasts (HAAFs). Methods: Our research included 3 groups: ① IFI16-siRNA group, specific small interference RNAs (siRNAs) of IFI16 were transfected into HAAFs in vitro to make IFI16 gene silence, ②Con-siRNA group, non-specific siRNAs were transfected into HAAFs as negative control and ③Untreated HAAFs group, blank control. HAAFs cell cycle and apoptosis rate were examined by flow cytometry, IFI16 mRNA expression was measured by real time qRT-PCR, protein expressions of IFI16, p53, p21, Bax and Bcl-2 were detected by Western blot analysis. Results: Compared with Con-siRNA group and Untreated HAAFs group, IFI16-siRNA group showed decreased apoptosis rate of HAAFs (3.33±0.41) % vs (7.42±1.51) % and (6.49±1.10) %, P<0.05, reduced ratio of G0/G1 phase cells (56.64 ± 4.77 ) % vs (69.67±3.54) % and (68.29±4.14) %, P<0.05, while increased ratio of S phase cells (25.23±5.19)% vs (13.76±2.07) % and (14.04±3.00) %, P<0.05. Meanwhile, IFI16-siRNA group presented down-regulated IFI16 mRNA and protein expressions, decreased protein levels of p53, p21, Bax and increased protein level of Bcl-2, all P<0.05. Conclusion: Inhibited IFI16 expression could decrease HAAFs apoptosis, promote cell cycle transition from G1 to S phase which might be related to the suppression of p53/p21 signaling pathway and regulation of Bax/Bcl-2 expression.
