摘　　要：目的:探讨血浆D-二聚体水平与慢性阻塞性肺疾病急性加重期(AECOPD)相关性胸腔积液之间的关系。方法:71例研究对象分为A组(AECOPD合并胸腔积液组)27例,B组(单纯AECOPD组)31例及C组(非COPD组,对照组)13例,并将A组随机分为A1组13例及A2组14例,所有入选AECOPD患者均按照COPD诊治指南治疗,A1组在规范治疗方案基础上加用低分子肝素钙治疗。观察治疗前后血浆D-二聚体及胸腔积液量。结果:①D-二聚体水平:治疗前A1组及A2组血浆D-二聚体水平均明显高于B组(P<0.05),而A、B组均明显高于C组(P<0.05);治疗1周后A1组D-二聚体水平较A2组、B组下降(P<0.05),2周后与C组对比,无明显差异(P>0.05),而A2组、B组D-二聚体水平下降缓慢,4周后与C组对比,无明显差异(P>0.05)。②胸腔积液量:治疗前A1、A2组之间胸腔积液量无明显差异(P>0.05);治疗2周后两组患者胸腔积液量均减少(P<0.05),而A1组胸腔积液量少于A2组(P<0.05);治疗4周后A1组所有患者胸腔积液全部吸收,而A2组仍有5例患者存在少量胸腔积液(P<0.05)。③胸腔积液量与血浆D-二聚体呈正相关(r=0.607,P<0.05)。结论:AE-COPD相关性胸腔积液的发病可能与肺循环高凝状态有关。使用低分子肝素钙治疗可加快AECOPD相关性胸腔积液的吸收。Objective：To explore the association between plasma D-dimer and pleural effusion related to acute exacerbation chronic obstruction pulmonary disease （AECOPD）. Methods： Seventy one patients were divided into AECOPD with pleural effusion group （group A, n =27）, AECOPD without pleural effusion group （group B, n ：31） and control group （groupC, n=13）. Group A were randomly divided into group A1 （ n =13） and group A2 （ n =14）. All AECOPD patients were treated with conventional therapy based on GOLD. In group A1 ,patients were subcutaneous injected a dose of low molecular weight heparin calcium once a day for 7 days. The concentrations of plasma D-dimer in peripheral blood were detected and chest CT was assessed in patients before and after treatment. Results： ①Plasma D-dimer： The concentra tion of plasma D-dimer was higher in group A （there was no difference between groups A1 and A2, P 0.05） than in group B （ P〈0.05）, and was higher in group B than in group C （ P〈0.05）. The concentration of plasma D-dimer was decreased in group A1 as compared with group A2 after one week＇s therapy （ P〈0.05）, and there was no difference in plasma D-dimer between groups A1 and C at 2 weeks （ P〉0.05）. There were no differences in plasma D-dimer among groups A, B and C at 4 weeks （ P〉0.05）. ② Pleural effusion quantity： Before therapy, there was no difference on pleural effusion quantity between groups A1 and A2 （ P〉0. 05）. The pleural effusion quantity was decreased in group A1 as compared with group A2 （ P〈0.05） at 2 weeks and fully absorption at 4 weeks, while in group A2, the pleural effusion absorption was slow, and there were still five patients with small pleural effusion quantity at 4 weeks.③There was positively correlated between plasma D dimer and pleural effusion quantity （ P 〈0.05）. Conclusion： There was hypercoagulable state in patients with AECOPD and might lead to the pleural effusion. Treatment with low molecular heparin calcium
