目的探讨自拟凉血解毒汤加减联合西医治疗对小儿过敏性紫癜(HSP)患者血清炎性因子、免疫功能及凝血功能等生化指标的影响。方法收集96例小儿HSP患者依据随机数据表法分为对照组(n=48)及观察组(n=48),对照组患儿给予常规西医对症支持治疗,观察组在对照组基础上联合自拟凉血解毒汤加减治疗,连续治疗2个月;比较治疗前后2组的炎性因子、免疫功能和和凝血功能指标水平。结果观察组治疗后,TNF-α、IL-6、IL-10和FIB水平显著低于对照组,CD3~+、CD4~+、APTT和PT水平显著高于对照组,差异均有统计学意义(P<0.05);2组CD8+水平比较差异无统计学意义(P>0.05),2组治疗后CD4~+/CD8~+水平较组内治疗前均显著升高,差异均有统计学意义(P<0.05),观察组与对照组比较差异无统计学意义(P>0.05)。结论自拟凉血解毒汤加减联合西医治疗小儿过敏性紫癜的疗效显著,可有效降低患者的炎性因子水平,改善免疫功能及凝血功能,值得临床推广。 Objective To explore the effects of self-made cooling blood and Jiedu Decoction combined with western medicine on serum biochemical indexes such as serum inflammatory factor, immune function and coagulation function in children with Henoch-Schonlein purpura (HSP). Methods A total of 96 pediatric patients with HSP were divided into control group (n = 48) and observation group (n = 48) according to randomized data table. The control group was given conventional western medicine symptomatic supportive treatment. The observation group was combined with the control group Qiangshen Jiedu Decoction plus treatment, continuous treatment for 2 months; compared before and after treatment of inflammatory cytokines, immune function and coagulation function indicators. Results The levels of TNF-α, IL-6, IL-10 and FIB in the observation group were significantly lower than those in the control group, and the levels of CD3 +, CD4 +, APTT and PT in the observation group were significantly higher than those in the control group (P <0.05). There was no significant difference in the level of CD8 + between the two groups (P> 0.05). The levels of CD4 ~ + / CD8 ~ + in two groups after treatment were significantly higher than those before treatment (P <0.05). There was no significant difference between the observation group and the control group (P> 0.05). Conclusion Self-made cooling blood Jiedu Decoction combined with western medicine treatment of children with Henoch-Schonlein purpura has a significant effect, which can effectively reduce the level of inflammatory cytokines in patients, improve immune function and coagulation function, worthy of clinical promotion.
