摘要 目的:觀察苏子降气汤对慢性阻塞性肺疾病急性发作期(痰浊壅肺证)患者肺功能和生命质量的影响,并探讨其部分机制。方法:选取2015年1月至2017年5月辽宁中医药大学附属医院呼吸内科住院的AECOPD(痰浊壅肺证)患者共108例,通过随机数字表法将108例患者按照随机编号分成对照组与观察组,每组54例;观察组:在对照组西药治疗的基础上根据中医辨证论治予苏子降气汤口服。根据量化的中医证候评分变化、肺功能和生命质量观察苏子降气汤对AECOPD(痰浊壅肺证)的影响,并采用酶联免疫吸附试验(ELISA)法检测IL-21和CXCL13的水平。结果:与治疗前比较,2组中医证候评分明显降低(P<0.05),且观察组治疗后的中医证候评分明显低于对照组(P<0.05)。治疗后2组肺功能均较治疗前有所提高,然而观察组肺功能的主要指标FVC(L)、FEV1(L)、FEV1/FVC(%)和PEF(L/s)明显优于对照组(P<0.05)。治疗后观察组生命质量评定症状、活动、影响和平均分均显著低于对照组(P<0.05)。治疗后IL-21和CXCL13的表达水平2组均明显下降(P<0.05),且观察组优于对照组(P<0.05)。结论:苏子降气汤可明显改善AECOPD(痰浊壅肺证)患者的病情,提高患者的肺功能及生命质量,其作用机制可能与降低外周血IL-21及CXCL13水平有关。

慢性阻塞性肺疾病(ChronicObstructivePulmonaryDisease,COPD)是临床多发疾病,以不完全可逆性气流受限为主要临床特征,病情多呈反复发作性及渐进性[1],目前西药治疗COPD虽可在一定程度改善病情但无法改变病情进展的状况,患者最终仍可因呼吸循环衰竭而威胁生命。近年来发现中草药辅助治疗可明显改善COPD的临床疗效,COPD属于中医学“肺胀”等范畴,痰在本病的病因病机中占据了关键位置,肺气郁滞而见咳喘痰多,肾阳虚衰则肾不纳气,水得不到温煦致化气无源,水泛为痰,故益肺补肾为治疗COPD要点。苏子降气汤首载于《太平惠民和剂局方》[2-3],具有降气平喘、祛痰止咳的功效,以“治上顾下,标本同治”的配伍特点广泛运用于现代临床呼吸道疾病的治疗。……
