煤工尘肺(CWP)大块纤维化是指煤矿工人肺内出现直径至少为2cm的尘性纤维化病变,通常具有进行性和大块样两个特点,因而又称谓进行性大块纤维化(progressive massive fibrosis,简称(PMF).国外则把CWP分为单纯性和复杂性两型,复杂性尘肺又常被用作PMF的同义词.PMF是晚期尘肺的表现,也是导致煤工丧失劳动能力和过早死亡的重要原因.近年来国内外学者对煤工PMF作了大量深入的研究,这不仅对进一步了解PMF组织发生,而且对提高PMF的
Coal worker’s pneumoconiosis (CWP) Bulk fibrosis refers to coal miners appear within the lung diameter of at least 2cm in diameter of fibrosis, usually with progressive and large samples of two characteristics, which is also known as progressive massive fibrosis ( progressive massive fibrosis (referred to as PMF) .While abroad is divided into two types of simple and complex CWP, the complexity of pneumoconiosis is often used as a synonym for PMF.PMF is the performance of advanced pneumoconiosis, but also lead to incineration workers and In recent years, scholars at home and abroad have made a great deal of in-depth research on coal industry PMF, which is not only helpful for further understanding of PMF organization, but also for improving PMF
