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 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.

Caco-2 cell monolayer model is widely utilized in drug absorption study and 12-well transwellTM plates were commonly used to study the absorption of different kinds of natural products. To establish a stable method for the study of traditional Chinese medicine prescription, 6-well plates were chosen because of the larger well volumes than 12-well plates. To study the impacts of collagen kinds, coating density as well as coating time on the cell culture, the transepithelial electrical resistance of Caco-2 cell monolayers grown on different collagen coating transwells was determined, and the permeations of propranolol and atenolol as standard markers were detected with HPLC. The results showed that the kinds of collagen, the different coating densities and coating time of rat tail collagen had no significant influences on the Caco-2 cell monolayer integrality and absorption capacity. 6-well plates coated with 2 micro g Scm-2 rat tail collagen for 1 hour were enough reliable and suitable for the study of traditional Chinese medicine prescription in vitro.

To study ecology suitability rank dividing of the total alkaloid content of Coptis Rhizoma for selecting artificial planting base and high-quality industrial raw material in Chongqing province. Based on the investigation of PCB and DEM data of Chongqing province, the relationship between the total alkaloid content in Coptis Rhizoma and topographical conditions was analyzed by statistical analysis. The geographic information systems (GIS)-based assessment and landscape ecological principles were applied to assess eco logy suitability areas of Coptis Rhizoma in Chongqing. slope, aspect and altitude are main topographical factors that affect the content of the total alkaloid content in Coptis Rhizoma The total alkaloid content in Coptis Rhizoma is higher in the lower altitude, shady slope and bigger slope areas. The total alkaloid content is higher in the south areas of Chongqing province and lower in the northeast. Terrain conditions of the southern region of Chongqing are most suitable for The accumulated of total alkaloid Coptis Rhizoma content.

OBJECTIVETo investigate the effects of Artesunate(Art) on the LX-2 cell.
METHODSThe cultured hepatic stellate cells were divided into control group and Art-treated groups with 250,350,450 µmol/L. The rate of cellular proliferation was detected by MIT assay, the content of ceramide (Cer)was determined by HPLC method, the content of hydroxyproline (Hyp) was determined by enzyme digestion method, the expressions of PPAR-γ, p53 and Caspase 3 were detected by Western blot.
RESULTSCompared with control group, IX-2 treated with Art were inhibited in a concentration-dependent manner(P < 0.01). Art could significantly increase the content of cerarnide in LX-2 ( P <0.01), and the content of Hyp was significantly decreased (P <0.05, P <0.01). The expressions of PPAR-γ, p53 and Caspase 3 were increased compared with that of control group(P < 0.01).
CONCLUSIONArtesunate could inhibit the proliferation and induce apoptosis of hepatic stellate cells through upregulating ceramide.
