Abstract:
To observe the clinical curative effect of Qingying Tang in the treatment of psoriatic blood-heat syndrome and explore its intrinsic mechanism.In this study,we collected 72 patients with blood-heat syndrome psoriasis admitted to our dermatology clinic from January 2016 to December 2017 and divided into control group and observation group according to the random number table method,36 cases in each group.The patients in control group were given with Acitretin Capsules orally,10 mg/time,twice a day.The patients in observation group were given with Qingying Tang orally,150 mL/time,twice a day.The treatment period was 12 weeks in both groups.The traditional Chinese medicine(TCM) syndrome scores before and after treatment,psoriasis area and severity index(PASI) score,dermatology life quality index(DLQI) score,and the clinical efficacy of the two groups were compared between the two groups;flow cytometry was used to detect peripheral blood Th17 cell percentages before and after treatment in both groups;serum interleukin(IL)-17,IL-23,IL-22,and IL-21 levels in both groups before and after treatment were measured by ELISA;the expression levels of STAT3 and RORγt before and after treatment in patients were measured by using skin lesion immunohistochemical method.The results showed that the TCM symptoms were improved significantly in both groups(P<0.05),and the effect in observation group was significantly better than that in the control group(P<0.05).PASI and DLQI scores were decreased significantly after treatment in both groups(P<0.05),and the scores in observation group were significantly lower than those in the control group(P<0.05).The curative effect of the observation group was significantly higher than that of the control group(P<0.05).After treatment,the percentage of Th17 cells,as well as IL-17,IL-23,IL-22 and IL-21 levels in peripheral blood were significantly decreased in both groups(P<0.05),and the levels in observation group were significantly lower than those in the control group(P<0.05).The expression levels of STAT3 and RORγt in both groups were significantly lower than those before treatment(P<0.01),and the levels in observation group were significantly lower than those in the control group(P<0.05).All of the results indicted that Qingying Tang can effectively improve the skin lesions and TCM syndrome in patients with psoriasis and blood-heat syndrome,and improve patient health quality,which may be related to regulation of peripheral blood IL-23/Th17.
