目的观察小儿消积止咳口服液治疗儿童慢性咳嗽的疗效及机制。方法选取慢性咳嗽患儿110例,随机分为对照组与观察组,每组55例。对照组患儿给予常规治疗,观察组患儿在常规治疗的基础上给予小儿消积止咳口服液治疗。另选取同期健康体检儿童5...目的观察小儿消积止咳口服液治疗儿童慢性咳嗽的疗效及机制。方法选取慢性咳嗽患儿110例,随机分为对照组与观察组,每组55例。对照组患儿给予常规治疗,观察组患儿在常规治疗的基础上给予小儿消积止咳口服液治疗。另选取同期健康体检儿童55例作为健康组。比较观察组与对照组的疗效,治疗前后评估咳嗽评分及匹兹堡睡眠质量指数(Pittsburgh sleep quality index,PSQI),检测治疗前后外周血嗜酸性粒细胞(eosinophils,EOS)、降钙素原(procalcitonin,PCT)、肿瘤坏死因子-α(tumor necrosisfactor-α,TNF-α)、干扰素-γ(interferon-γ,IFN-γ)、白细胞介素(interleukins,IL)-4(IL-4)、IL-8以及免疫球蛋白(immunoglobulin,Ig)A、IgG和IgM水平,检测肺功能包括用力肺活量(forced vital capacity,FVC)、第1秒用力呼气量百分比(the percentage of forced expiratory volume in the first second,FEV_(1)%)和呼气峰值流速(peak expiratory flow rate,PEF)。结果观察组的总有效率高于对照组,体温复常时间、肺啰音消失时间、咳痰消失时间及咳嗽消失时间均较对照组缩短,治疗后咳嗽评分及PSQI评分均低于对照组(P<0.05)。观察组和对照组治疗前的外周血EOS、PCT、TNF-α、IL-4和IL-8水平均高于健康组,IFN-γ、IgA、IgG和IgM水平均低于健康组(P<0.05);治疗后,观察组和对照组的外周血EOS、PCT、TNF-α、IL-4和IL-8水平均降低,IFN-γ、IgA、IgG和IgM水平均降低,FVC、FEV_(1)%和PEF均升高,且观察组上述指标均明显优于对照组(P<0.05)。结论外周血EOS、PCT、TNF-α、IL-4和IL-8水平在儿童慢性咳嗽中明显升高,IFN-γ水平明显降低,采用小儿消积止咳口服液治疗能够调节上述各指标平衡,提高临床疗效并促进症状缓解。展开更多
