摘要
Objective:To explore the therapeutic effect of auricular therapy combined with optimized Yinxieling Formula(银屑灵优化方) on psoriasis vulgaris.Methods:A randomized controlled single-blind clinical trial on 84 outpatients with psoriasis vulgaris was conducted.The patients were randomized to a treatment group(43 cases treated by auricular therapy combined with optimized Yinxieling Formula) and a control group (41 cases treated by optimized Yinxieling Formula alone) according to a random number generated by SPSS 17.0 software.The treatment duration for both groups was 8 weeks.The therapeutic effect was comprehensively measured by the primary outcome measure[Psoriasis Area and Severity Index(PASI) reduction rate]and the secondary outcome measure[PASI,Visual Analogue Scale(VAS),Dermatology Life Quality Index(DLQI), Self-rating Depression Scale(SDS),and Self-rating Anxiety Scale(SAS)].The outcomes of both groups were obtained and compared before and after the intervention.Results:The PASI reduction rate in the treatment group was 74.4%(32/43),which was higher than that in the control group(36.6%,15/41,P<0.01).The PASI scores decreased in both groups after treatment and was lower in the treatment group compared with the control group (P<0.01).With stratified analysis,there were significant differences between the PASI scores in the following subgroups:age 18-30,baseline PASI>10 and stable stage(P<0.05).DLQI decreased in both groups on some categories after treatment,but there were no significant differences between the two groups in SDS,SAS and VAS(P>0.05).No obvious adverse reactions were found in either group.Conclusion:The therapeutic effect of auricular therapy combined with Optimized Yinxieling Formula was superior to Optimized Yinxieling Formula alone with no obvious adverse reaction.
