OBJECTIVE:To establish quality control method for rupining strapping.METHODS:The qualitation of Herba Epimedii,Rhizoma Bolbostemmae and fructus toosendan in rupining strapping was conducted by TLC.The principal drug-epimedium herb was determined by column chromatography-HPLC.RESULTS:Herba Epimedii,Rhizoma Bolbostemmae and fructus toosendan could all be identified in TLC.Good linear correlation of icariin was observed when the sample size was0.428?g～2.568?g(r=0.9998).The average recovery was94.57%(RSD=1.43%).CONCLUSION:The method is sensi-tive,accurate,and reproducible.It can be used for the quality control of rupining stripping.

Objective:To evaluate the clinical efficacy of microneedle radiofrequency in the treatment of moderate acne vulgaris.Methods:From August 2018 to August 2020, 393 patients (192 males and 201 females, aged 15-38 years) with moderate acne were enrolled in the Department of Dermatology, the First Affiliated Hospital of Shantou University Medical College and Shantou Chaonan Minsheng Hospital, including 201 patients in experimental group and 192 patients in control group. In the experimental group, microneedle radiofrequency therapy was used once every 2 weeks for 3 times in total. The control group adopted the fire needle, once every 2 weeks, a total of 3 times. The efficacy of both groups was evaluated at week 8.Results:A total of 378 patients were actually completed: 196 patients in the experimental group, and 182 patients in the control group. At the eighth week of follow-up, the total effective rate was 81.12% in the experimental group and 70.43% in the control group. The efficacy of the two groups was statistically different (χ 2=4.42, P<0.05). Conclusions:The efficacy of microneedle radiofrequency therapy in the treatment of moderate acne vulgaris is better than that of fire needle, with good tolerance, short recovery period, few adverse reactions and high compliance, which has clinical promotion value.
