【摘要】 慢性阻塞性肺疾病是一种常见、多发、死亡率较高的呼吸系统慢性疾病，感染是造成慢阻肺急性加重最主要的诱因；近年来，血清淀粉样蛋白A及肝素结合蛋白作为较新的感染指标，因其反应迅速，检验灵敏度、特异度较高等优势，在呼吸系统疾病领域越来越受到关注。将对HBP、SAA在慢阻肺急性加重合并肺部感染方面的研究进展进行概括归纳，为临床诊断和评估预后提供参考。更多还原

【Abstract】 Chronic obstructive pulmonary disease is a common,frequent and high mortality chronic disease of the respiratory system,while infection is the main cause of acute exacerbation of COPD;In recent years,serum amyloid A and heparin-binding protein have received increasing attention in the field of respiratory diseases as newer indicators of infection because of their rapid response,sensitivity and specificity;This article will summarize the research progress of HBP and SAA in acute exacerbation of chronic obstructive pulmonary disease combined with pulmonary infections,and provide a reference for clinical diagnosis and assessment of prognosis.更多还原
