Objective: To study the effect of Yinxieling decoction on PASI, TNF-α and IL-8 in patients with psoriasis vulgaris. Methods: A total of 120 cases of psoriasis vulgaris were divided into 4 groups according to syndrome differentiation of TCM and randomized controlled method: wind heat syndrome group (group A), blood stasis syndrome group (group B), blood dryness syndrome group (group C) and control group (group D) (n=30 per group). Patients in observation groups were treated with Yinxieling decoction, while patients in control group were treated by placebo for 8 weeks. Levels of TNF-α and IL-8 were determined before treatment, 4 and 8 weeks after treatment. psoriasis area and severity index score was also performed before and after treatment. Results: psoriasis area and severity index score and serum level of TNF-α, IL-8 were significantly decreased in all groups. The decrease in three observation groups was more significant (P<0.05 or P<0.01), and the decrease in wind heat syndrome group was the most significant (P<0.01). psoriasis area and severity index was positively correlated with TNF-α and IL-8, respectively (P<0.05). Conclusions: Yinxieling decoction has therapeutical effect on psoriasis vulgaris via regulating TNF-α and IL-8. © 2014 Hainan Medical College.
