我国职业病患者中发病人数最多、最严重的是尘肺,其中以矽肺最为突出。矽肺是因长期吸入粉尘致肺组织弥漫性纤维化,由于患者的接尘年龄不同和接尘工龄不同,因此发病年龄和肺功能下降程度亦不同。晚发性矽肺是曾经接触高浓度粉尘作业的工人X线胸片未发现明显异常,或者胸片异常不明显尚未确诊矽肺,脱离粉尘环境若干年后才被确诊的矽肺患者。本文通过回顾我院诊断的老年晚发性矽肺患者的发病情况及肺功能状况,并对其生存质量进行评分,旨在为防治老 Occupational disease in China the largest number of patients, the most serious is pneumoconiosis, of which the most prominent silicosis. Silicosis is diffuse fibrosis due to long-term inhalation of dust caused by the lung tissue, due to the different age of patients with dust and the different dust-receiving age, so the incidence of age and lung function decline is also different. Late silico-silicosis is a patient with silicosis who has not been diagnosed with X-ray before a high-level dust exposure or has not been diagnosed with an abnormal chest radiograph, and has been diagnosed several years after leaving the dusty environment. In this paper, by reviewing the incidence of elderly patients with silicosis of the elderly diagnosed in our hospital and lung function status, and to assess the quality of life, aimed at the prevention and treatment of old
