Objective] To investigate Wuweixiaodu drinks combined Pipaqingfei drinks curative effect for the treatment of acne due to the lung by wind and heat.[Methods] 120 patients from Hospital of Zhejiang Province Dermatologists,using a random number table divided into treatment group of 60 patients and a control group of 60 patients.The treatment group received Wuweixiaodu drinks together with Pipaqingfei drinks,one day one decoction; control group was given Danshentong capsules orally,4 pills,4 times a day.Each set to four weeks for a course of treatment.[Results] After a course of treatment, the rate of basic recovery from treatment group was 86.67%,and the control group was 58.33%,having a significant difference(P<0.05).Lesions scores after treatment between the two groups,the scores of gradeⅠ,Ⅱacne treatment group had statistically significant difference(P<0.05) after treatment,the scores of grade Ⅲ, Ⅳ acne treatment group had a very significant difference(P<0.01) after treatment.[Conclusion] Wuweixiaodu drinks with Feijingfengre drinks is effective to acne due to the lung by wind and heat,therapeutic effect for severe acne is better and has less adverse reactions.

ObjectiveThis study was to explore the feasibility of using the orthogonal plane dose formed by the coronal and sagittal plane to verify the volumetric modulated arc therapy (VMAT) plan.MethodsThe VMAT plans of 12 patients were included in this study.The orthogonal plane dose formed by the coronal and sagittal plane were measured based on the combination of 2D ionization chamber array and multicube phantom,and the point dose were measured based on a multiple hole cylindrical phantom attached with two 0.125 cm3 ionization chamber probes.ResultsIn the measurement of the point dose,the average error was 1.5％ in high dose area ( more than 80％ of maximum),and 1.7％ in low dose area ( less than 80％ of maximum),respectively.The discrepancy of point dose measurement was 1.3％ between the 2D ionization chamber array and the VMAT planning system.In the measurement of the orthogonal plane dose,the pass rate of γ were 93.7％ for 2％/2 mm and 97.2％ for 3％/3 mm.ConclusionIt is reliable for using the orthogonal plane dose formed by the coronal and sagittal plane to verify the VMAT plan.
