Objective To assess the clinical efficacy and safety of benzoyl peroxide gel(BPG)with different concentrations in the treatment of acne vulgaris,and to compare the quality between the domestic products with imported products.Methods The study was an open-controlled clinical trial.The patients were divided into4groups:imported2.5%,5%,10%gel and domestic5%gel.All preparations were ap-plied twice daily for6weeks.Study visits took place at baseline and week2,4and6.Results Different concentrations of benzoyl peroxide gel were effective for inflammatory lesions.The longer the course of treat-ment and the higher the drug concentration were,the better global clinical efficacy was,and the optimum concentration was5%or10%.In addition,the higher the drug concentration was,the higher adverse reac-tion rate was.Transient and mild local skin irritation occurred but was well tolerated by the patients.The imported benzoyl peroxide5%gel was as effective as domestic benzoyl peroxide5%gel,but the adverse re-action rate was less than the latter.Conclusion Different concentrations of benzoyl peroxide gel are all ef-fective and safe in the treatment of acne vulgaris,with the optimum concertration is5%or10%.

Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.
