矽肺是由于长期吸入游离二氧化硅(Silicon dioxide,SiO_2)水平较高的粉尘所引起的以肺组织纤维化为主的全身性疾病。矽肺是尘肺病中最为常见、进展最快和危害最为严重的一种病种[1]。人们对于矽肺发病机制的研究长达一个多世纪,提出了近百种学说,但迄今仍无法全面解释其发病过程。近年来,粉尘与机体的交互作用受到了越来越多的关注。当SiO_2粉尘进入机体后,首先与肺泡巨噬细胞(Alveolar
Silicosis is caused by long-term inhalation of free silicon dioxide (Silicon dioxide, SiO 2) higher levels of dust caused by pulmonary fibrosis-based systemic diseases. Silicosis is the most common form of pneumoconiosis, the most advanced and the most dangerous one [1]. People study the pathogenesis of silicosis for more than a century, put forward nearly a hundred kinds of theory, but so far still can not fully explain the pathogenesis. In recent years, dust and the body’s interaction has been more and more attention. When SiO 2 dust enters the body, it first interacts with alveolar macrophages
