大环内酯类药物的抗菌外作用与临床应用专家共识
Important/potential value of macrolides has been proved in the management of chronic respiratory diseases by increasing basic and clinical trials.Through three face-to-face discussions,10 experts examined important data and drafted this consensus related to macrolides:(1) mechanism of nonantiinfective effects;(2) clinical use in chronic respiratory diseases;(3) cautions of long-term use.The mechanism out of non-antiinfective effects includes anti-inflammatory effect,modifying airway secretion,immune-regulation related to antibacterial effect,corticoid saving effect and anti-viral effect.The efficacy of long-term use of low-dose macrolides is definitely confirmed in diffuse panbronchiolitis,chronic rhinosinusitis.It is considerably used in bronchiectasia,cystic fibrosis,severe asthma and chronic obstructive pulmonary disease.Further studies should be conducted in cryptogenic organizing pneumonia and respiratory viral infection.It should be paid attention to its possible adverse effects (including drug interactions,cardiac toxicity,ototoxicity and disturbance of intestinal flora) and drug resistance in long-term use.A Chinese consensus for non-antiinfective effects and clinical use of macrolides is developed for the first time,which aims to expand their rational use and the further research.

弥漫性泛细支气管炎3例CT表现并文献复习
弥漫性泛细支气管炎(diffuse panbronchiolitis,DPB)[1-2]是弥漫存在于两肺以呼吸性细支气管炎为主要区域的特殊气道炎性疾病,目前发病机制不明确,临床表现缺乏特异性,主要症状为咳嗽、咳痰、呼吸急促等,临床上容易误诊、漏诊,严重者可导致呼吸功能障碍.随着对本病认识的深入,我国近些年来已有陆续报道,说明我国DPB并非少见病例.现对本院经病理或临床诊断的3例DPB进行回顾性分析,并对国内外相关文献进行复习,提高对DPB的CT表现和临床特点的认识及诊断能力.
