摘要: 目的 探讨西替利嗪辅助治疗对哮喘急性发作期患儿肺部通气功能及外周血巨噬细胞中Toll样受体(TLR)水平的影响。 方法 选择空军军医大学第二附属医院120例哮喘急性发作期患儿为研究对象,根据随机数字表法分为试验组(n=60)、对照组(n=60)。对照组采用布地奈德雾化吸入治疗,试验组在对照组基础上应用西替利嗪辅助治疗, 2组均治疗5 d。治疗5 d后,对比2组疗效、临床症状消失时间、不良反应; 观察治疗前、治疗5 d后肺部通气功能[第1秒呼气量(FEV1)、用力肺活量(FVC)、呼气高峰流量(PEFR)]、外周血巨噬细胞中TLR1、TLR2、TLR4水平的变化。 结果 试验组治疗5 d后总有效率为91.67%, 高于对照组的75.00%(P<0.05); 试验组喘息、咳嗽、肺部哮鸣音消失时间短于对照组(P<0.05); 2组治疗5 d后FEV1、FVC、PEFR水平较治疗前提高,且试验组高于对照组(P<0.05); 2组治疗5 d后外周血巨噬细胞中TLR1、TLR2水平较治疗前提高,且试验组高于对照组,TLR4水平较治疗前降低,且试验组低于对照组,2组比较差异均有统计学意义(P<0.05); 2组不良反应发生率相比,差异无统计学意义(P>0.05)。 结论 应用西替利嗪辅助治疗可增强哮喘急性发作期患儿的疗效,提升肺部通气功能,改善外周血巨噬细胞中TLR水平,促进患儿康复,且安全性较高。Abstract: Objective To explore the effect of cetirizine adjuvant therapy on pulmonary ventilation function and Toll-like receptor(TLR)level in macrophages of peripheral blood in children with acute asthma attack. Methods A total of 120 children with acute asthma attack in Second Affiliated Hospital of Air Force Military Medical University were randomly divided into experimental group(n=60)and control group(n=60). The control group was treated with budesonide aerosol inhalation and the experimental group was treated with cetirizine on the basis of the control group, the treatments of two groups were lasted for 5 days. The therapeutic effects, the disappearance time of clinical symptoms, adverse reactions after 5 days of treatment were observed. Lung ventilation function [forced expiratory volume In one second(FEV1), forced vital capacity(FVC), peak expiratory flow rate(PEFR)] and the levels of TLR1, TLR2 and TLR4 in macrophages of peripheral blood before and after 5 days of treatment were also compared. Results The total effective rate of the experimental group was 91.67%, which was higher than 75.00% of the control group after 5 days of treatment(P< 0.05); the disappearance time of wheezing, coughing and lung wheezing in the experimental group- were shorter than that in the control group(P< 0.05); the levels of FEV1, FVC and PEFR after 5 days of treatment in the two groups were higher than those before treatment, and the experimental group was higher than those in the control group(P< 0.05); the levels of TLR1 and TLR2 in blood macrophages were higher than those before treatment, and the level of TLR4 in the experimental group was lower than those in the control group, and the experimental group was better than that in the control group(P< 0.05). There was no significant difference in the incidence of adverse reactions between the two groups(P >0.05). Conclusion Cetirizine adjuvant therapy can enhance the curative effect, pulmonary ventilation function, improve the level of TLR in macrophages of peripheral blood, and promote the recovery of children with acute asthma attack, and it is safer.
