本期笔谈由各科临床医生从各自角度介绍了各科的胸腔积液,涉及范围较广。但由于引起胸腔积液的原因较多,虽然最后简介了几种少见的胸腔积液,也难将临床上所有的胸腔积液包括进来。为此,希望读者看后能来信提出还应补充哪些胸腔积液,并对这种专题多议的形式提些看法和建议,促进本刊更好地为临床服务。 In this issue, the clinicians from each department introduced the hydrothorax in various subjects from a wide range of perspectives. However, due to pleural effusion caused by many reasons, although the last brief introduction of several rare pleural effusion, it is difficult to include all clinical pleural effusion. To this end, I hope readers can see after the letter proposed what pleural effusion should be added, and to discuss the form of such topics to raise some ideas and recommendations to promote better service for clinical publications.
