国内外对接尘者吸烟的危害相关研究屡见报道,早在20世纪70年代,Cohen等就发现烟草烟雾中的氢氰酸能伤害支气管上皮及其纤毛,导致其消除粉尘功能下降[1]。近期的大型前瞻性队列研究结果也进一步证实吸烟可协同粉尘致接尘工人死亡危险性明显增加[2]。可是在临床工作中,我们发现尘 Studies on the hazards of smokers at home and abroad frequently reported that as early as the 1970s, Cohen et al. Found that hydrocyanic acid in tobacco smoke can damage bronchial epithelium and its cilia, resulting in the reduction of dust function [1]. Recent large-scale prospective cohort study also further confirmed that smoking can be associated with the risk of dust-induced workers death significantly increased [2]. However, in clinical work, we found that dust
