Abstract:Objective To analyze the effect of modified Xijiao Dihuang Decoction on primary immunologic thrombocytopenic purpura and the level of T lymphocyte subsets. Methods A total of 76 patients with primary immunologic thrombocytopenic purpura admitted to the First Hospital Jiaxing from January 2016 to February 2018 were selected for this study. According to the random number table method, they were randomly divided into conventional group and traditional Chinese medicine group, 38 cases in each group. The conventional group was treated with Prednisone Acetate Tablets, while the traditional Chinese medicine group was treated with modified Xijiao Dihuang Decoction (buffalo horn instead of rhino horn). After treatment, the effects total effective rate and relapse rate, traditional Chinese medicine symptom score, platelet count and T lymphocyte subsets CD3+, CD4+ and CD8+ of the two groups were compared. Results After treatment, there was no significant difference in the total effective rate and relapse rate between the two groups (P > 0.05). After treatment, the total effective rate of traditional Chinese medicine symptom improvement in traditional Chinese medicine group was higher than that in the conventional group (P < 0.05). After treatment, the platelet count of the two groups increased (P < 0.05), but there was no significant difference between the two groups (P > 0.05). After treatment, the levels of CD3+ and CD4+ in the two groups were higher, and the traditional Chinese medicine group were higher than those in the conventional group (P < 0.05); the levels of CD8+ in the two groups were lower, and the traditional Chinese medicine group was lower than that in the conventional group (P < 0.05). There were no adverse reactions in the two groups during the study. Conclusion Modified Xijiao Dihuang Decoction has a significant effect in the treatment of primary immunologic thrombocytopenic purpura, it can obviously improve the clinical symptoms of patients and the level of T lymphocyte subsets.
