摘要: 目的: 探讨N-乙酰半胱氨酸(NAC)治疗慢性阻塞性肺疾病(COPD)的临床疗效和作用机制。方法: 将78 例COPD 患者随机分为治疗组和对照组,观察其治疗前后对痰液炎症细胞计数及核因子-kB(NF-kB)、白细胞介素8(IL-8)、肿瘤坏死因子α(TNF-α)水平的影响,以及对临床症状、肺功能指标和血丙二醛(MDA)、全血超氧化物歧化酶(SOD)和血清血管紧张素Ⅰ转换酶(ACE)活性及血内皮素-1(ET-1)含量的变化情况,并与20 名健康人作比较。结果: 78 例COPD 患者中脱落5 例(治疗组3 例,对照组2例)。NAC 治疗COPD 的总显效率为72.50 %,总有效率为87.50 %,与对照组比较有显著性差异(P<0.05)。与对照组比较,治疗组能明显改善肺功能指标(FEV1 、FVC 、mPAP)和血MDA 、SOD 、ACE 活性及ET-1 含量(P<0.05)。治疗后治疗组痰液中性粒细胞(PMN)、非中性粒细胞(mPMN);IL-8 、TNF-α和NFkB活性(A 值)较治疗前显著降低(P<0.01),降低作用优于对照组(P<0.05),治疗期间未见明显毒副作用。结论: NAC 治疗COPD 患者可改善其临床症状和肺功能,安全性良好,通过增强抗氧化能力和减轻COPD 患者气道炎症反应而发挥其治疗作用。

Abstract: AIM: To explore the clinical effect and mechanism of NAC on patients with chronic obstructive pulmonary disease (COPD).METHODS: 78 patients with COPD in stable phase were randomly divided into the treated grouPand the control group.Total and differential count of inflammatory cell in sputum,NF-kB,IL-8,TNF-α,and clinical symptom,FVC,FEV1,mPAPand the blood levels of malondialdchyde (MDA),superoxide dismutase (SOD),angiotensin-converting enzyme (ACE)and endothelins-1 (ET-1)were measured before and aftertreatment.RESULTS: 5 cases of the 78 patients dropped out.The rate of total marked effect and total effect were72.50 %,and 87.50 % respectively,in the treated group.All the indexes measured in patients before and aftertreatment were significantly different from those in healthy subjects (P<0.05).Differential count of polymorphonuclearneutrophil (PMN),the levels of IL-8 and TNF-α,the activity of NF-kB in sputum in the treated grouPdecreased aftertreatment (P<0.01),while the FEV1,FVC,mPAP,MDA,SOD,ACE,and ET-1 were ameliorated (P<0.05),and all were betterthan those in the control grouP(P<0.05).No obvious adverse effects were found.CONCLUSION: NAC used fortreating COPD is able to relive the clinical symptom and improve the lung function,with a fairly good safety,and can play a therapeutic role on patients with COPD by way of increasing anti-oxidative ability and reducing the airway inflammatory reaction.
