RESUMO
Objective To explore the effect of Qushi-Huaban granule for the allergic purpura and the impact on CD4+CD25+T cells. Methods A total of 80 children with allergic purpura from March 2014 to January 2016 were randomly divided into two groups, the control group and observation group, 40 in each group. The control group was given routine medicine andmontelukast chewable tablets. The observation group was treated with Qushi-Huaban granule on the basis of conventional therapy. The clinical effect, purpura recession time, recurrence rate before and after treatment were observed and compared. The serum levels of IFN-γ (interferon-γ, IFN-γ) and IL-5 were detected by ELISA. The expression level of CD4+CD25+ Treg were observed by flow cytometry before and after treatment. Results The effective rate of the treatment group [92.5% (37/40) vs. 72.5%(29/40), χ2=9.270] was significantly higher than control group (P＜0.01). After treatment, the serum IFN-γ levels in the observation group and the control group were significantly higher than those before treatment (t=3.960, 4.175, P＜0.05). The serum IL-5 levels of two groups were significantly lower than those before treatment (t=8.061, 8.776, P＜0.01).There was no significant differencein the serum INF-γ and IL-5 leves after treatment between two groups (P＞0.05). The regression time of purpura in the observation group (5.2 ± 1.1 d vs. 10.2 ± 2.4 d, t=12.460) was significantly shorter than that in the control group ( P＜0.01). The recurrence rate of the observation group was [7.4% (5/37) vs. 10.3% (3/29)] which was significantly lower than that of the control group, but the difference was not statistically significant (χ2=0.153, P=0.696). The CD4+CD25+T cells (t=7.367, 6.957, P＜0.05) and CD3+CD4+CD25+ T cells (t values were 9.080, 8.885, P＜0.05) of two groupswere significantly higher than those beforetreatment, butthere was no significant difference between the 2 groups after treatment ( P＞0.05). Conclusions The Qushi-Huaban granule combined with montelukast sodium for Henoch Schonlein purpura showed efficacy, and significantly increase the moisture level of T cell subsets.
