矽肺(硅肺)是一种常见的职业病,其基本病理变化是肺的弥漫性结节性纤维化,最终可导致肺源性心脏病,且易并发肺结核,后果严重。对其防治,虽做了大量工作,并取得了一些进展,但由于对其发病机理尚不清楚,故对防、治的主攻方向,难免掌握不定或有所偏重,致使矽肺依然是当前的一种危害性最为严重的尘肺。冶金部针对矽肺的防、治方向,提出了“两个延长”做为当前的奋斗目标,即在1990年以前,能延长接触矽尘作业工人的发病工龄到20年以上;延长矽肺病人的寿命到60岁以上。如何完成这一任务,的确是一项艰巨而迫切的重大课题。本文根据我组所见的17
Silicosis (silicosis) is a common occupational disease whose basic pathological changes are diffuse nodular fibrosis of the lungs, which can eventually lead to pulmonary heart disease and have complicated pulmonary tuberculosis with serious consequences. Although its prevention and treatment have done a great deal of work and some progress has been made, its pathogenesis is not clear yet. Therefore, it is inevitable that the main direction of prevention and cure will be uncertain or biased so that silicosis is still the current one The most dangerous pneumoconiosis. Metallurgical department for the prevention and treatment of silicosis, the proposed “two extensions” as the current goal, that is, in 1990, to extend exposure to silica dust exposed workers the working age to more than 20 years; extend the life of silicosis patients To over 60 years old. How to accomplish this task is indeed an arduous and pressing major issue. This article based on my group saw 17
