健脾补肺化痰方对小儿支气管哮喘缓解期肺功能的影响

【目的】观察健脾补肺化痰方对小儿支气管哮喘缓解期肺功能的影响,探讨中医药防治小儿支气管哮喘的机制。【方法】将60例支气管哮喘缓解期患儿随机分为治疗组和对照组各30例。对照组给予糖皮质激素(丙酸氟替卡松)吸入治疗,治疗组在对照组西药治疗的基础上,给予健脾补肺化痰方(由炙黄芪、太子参、炒白术、防风、茯苓、陈皮、半夏、炙甘草、煅龙骨、煅牡蛎、葶苈子等组成)治疗。观察并比较2组临床疗效及治疗1、2、3、6、9、12个月后呼气峰流速(PEF)值及呼气峰流速变异率(PEFv)等肺功能指标的变化情况。【结果】(1)治疗组总有效率为93.33%,显著优于对照组的83.33%(P0.05)。(2)在整个治疗过程中,治疗组患儿的PEF值均显著高于对照组,PEFv值均显著低于对照组,差异均有统计学意义(P0.05)。【结论】健脾补肺化痰方可改善肺脾气虚型支气管哮喘缓解期患儿的临床症状,增强患儿的肺功能,降低气道的高反应状态。

Clinical Study of Jianpi Bufei Huatan Recipe for Treatment of Pediatric Bronchial Asthma at Remission Stage

Objective To investigate the influence of Jianpi Bufei Huatan Recipe (JBHR), a Chinese herbal compound with the actions of strengthening spleen, tonifying lung and resolving phlegm, on the pulmonary function of childhood bronchial asthma at remission stage, and to explore the possible therapeutic mechanism. Methods Sixty bronchial asthma children at remission stage were divided into treatment group and control group, 30 cases in each group. Both groups were treated with inhalation of fluticasone propionate, and additionally, the treatment group was given oral use of JBHR(mainly composed of Radix Astragali, Radix Pseudostellariae, fried Rhizoma Atrctylodis Macrocephalae, Radix Saposhnikoviae, Poria, Pericarpium Citri Reticulatae, Rhizoma Pinelliae, prepared Radix Glycyrrhizae, calcined Os Draconis, calcined Concha Ostreae, and Semen Lepidii seu Descurainiae). The therapeutic effect of the two groups was evaluated after treatment, and the changes of peak expiratory flow(PEF), peak expiratory flow variation(PEFv) were also observed after treatment for 1, 2, 3, 6, 9, a nd 12 month(s). Results (1)The total effective rate of the treatment group was 93.33%, and that of the control group was 83.33%, the difference being significant(P<0.05). (2) During the treatment, PEF was higher and PEFv was lower in the treatment group than those in the control group(P<0.05). Conclusion JBHR could relieve the clinical symptoms, improve the pulmonary function and decrease the hyperactivity of airway of pediatric bronchial asthma at remission stage with lung-spleen qi deficiency.
