Objective To observe the efficacy and safety of Jiuwei Xifeng Granules in treatment of tic disorder in children with kidney-yin deficiency and liver-wind stirring Methods Randomized, doubled-blind, placebo parallel-controlled, multi-center trial, superiority test were designed for this study. Patients (144 cases) with tic disorder in First Teaching Hospital of Tianjin University of TCM etc. A total of 144 patients in four hospitals were randomly divided into treatment and control, and each group had 72 cases. Patients in the treatment group were po administered with Jiuwei Xifeng Granules, and patients in the control group were po administered with placebo. They were treated for six weeks. Results After treatment, disease curative efficacies in the control and treatment groups were 25.00% and 78.26%, respectively, and TCM symptoms efficacies in the control and treatment groups were 67.65%and 95.65%, and there was difference between two groups (P < 0.05). After treatment, movement integral, integral and total integral significantly decreased, and the difference was statistically significant in the same group (P < 0.05). After treatment, movement integral, integral and total integral in the treatment group were lower than those in the control group, and difference value of YGTSS integral was greater than that in the control group, and there was difference between two groups (P < 0.05). After treatment, the patients of 2 score of movement twitch score, voice twitch points in the treatment group were significantly more than those in the control group, and the patients of 4 score were less than those in the control group, and there was difference between two groups (P < 0.05). The patients of 0 score of feverishness in palms and soles, tidal fever and night sweating, and irascibility in the treatment group were significantly more than those in the control group, and the patients of 1 score were less than those in the control group, and there was difference between two groups (P < 0.05). Conclusion Jiuwei Xifeng Granules has clinical effective in treatment of tic disorder in children with kidney-yin deficiency and liver-wind stirring, and the effect is superior to placebo safely.
