摘　　要：目的探究慢性阻塞性肺疾病(COPD)患者血清及肺泡灌洗液中结缔组织生长因子(CTGF)、转化生长因子β1(TGF-β1)的水平及意义。方法选择2016年3月至2017年3月于该院就诊的COPD患者65例作为研究对象,按照疾病严重程度分为急性加重期组(32例)和稳定期组(33例);另选择35例体检健康者作为对照组。采用酶联免疫吸附试验(ELISA)方法分别检测各组受试者血清及肺泡灌洗液中CTGF、TGF-β1水平,同时测定COPD患者用力肺活量(FVC)、第一秒用力呼气容积(FEV1)及FEV1/FVC等肺功能指标,分析血清及肺泡灌洗液中CTGF、TGF-β1及其与肺功能的关系。结果急性加重期组COPD患者血清及肺泡灌洗液中CTGF、TGF-β1水平明显高于稳定期组和对照组,差异有统计学意义(P<0.05);稳定期组血清及肺泡灌洗液中CTGF、TGF-β1水平明显高于对照组,差异有统计学意义(P<0.05)。肺功能结果显示,急性加重期组肺功能指标FVC、FEV1、FEV1/FVC值较稳定期组、对照组明显降低,差异有统计学意义(P<0.05);稳定期FEV1、FEV1/FVC值较对照组明显降低,差异有统计学意义(P<0.05)。急性加重期组血清CTGF与肺泡灌洗液CTGF表达水平呈正相关,血清TGF-β1与肺泡灌洗液TGF-β1的表达水平亦呈正相关;血清中CTGF、TGF-β1水平呈正相关,肺泡灌洗液中CTGF、TGF-β1水平亦呈正相关;血清中CTGF、TGF-β1水平分别与FVC、FEV1、FEV1/FVC呈负相关,肺泡灌洗液中CTGF、TGF-β1水平亦分别与FVC、FEV1、FEV1/FVC呈负相关。结论 CTGF、TGF-β1表达水平与COPD的发生发展密切相关,可作为监测COPD病情的指标。Objective To explore connective tissue growth factor(CTGF)and transforming growth factorβ1(TGF-β1)detection levels in serum and bronchoalveolar lavage fluid of patients with chronic obstructive pulmonary disease(COPD)and significance.Methods Totally 65 patients with COPD treated in the hospital from March 2016 to March 2017 were selected as the subjects,the patients were divided into acute exacerbation group(32 cases)and stable phase group(33 cases)according to the severity of the disease.Another 35 cases of physical examination in the hospital were selected as the control group.Serum and bronchoalveolar lavage fluid CTGF and TGF-β1 levels were detected by using enzyme-linked immunosorbent assay(ELISA)method,and lung function index,such as forced vital capacity(FVC),forced expiratory volume(FEV1),and FEV1/FVC of patients with COPD were detected,and the relationship was analyzed of CTGF and TGF-β1 in serum and bronchoalveolar lavage fluid and lung function.Results CTGF and TGF-β1 levels in serum and bronchoalveolar lavage fluid in acute exacerbation group were significantly higher than those in stable group and control group(P<0.05).CTGF and TGF-β1 levels in serum and bronchoalveolar lavage fluid of the stable group were significantly higher than those in the control group(P<0.05).Lung function results showed that lung function index FVC,FEV1 and FEV1/FVC value in acute exacerbation group decreased significantly when compared with those in stable group and the control group(P<0.05).FEV1 and FEV1/FVC in the stable group was significantly lower than that in the control group(P<0.05).CTGF expression level was positively correlated in serum and bronchoalveolar lavage fluid of acute exacerbation group,and TGF-β1 was also positively correlated.Serum CTGF and TGF-β1 levels were positively correlated,and CTGF and TGF-β1 in alveolar lavage fluid were also positively correlated.Serum CTGF and TGF-β1 levels were negatively correlated with FVC,FEV1,FEV1/FVC,and CTGF and TGF-β1 in alveolar lavage fluid were negative
