[Investigation of newly diagnosed pneumoconiosis from artificial quartz stone manufacturers].

Artificial quartz dust exposure may cause associated pneumoconiosis. From November 2019 to July 2020, a total of 27 cases of silicosis associated with artificial quartz stone manufacturers were diagnosed and treated in the Occupational disease Department of Suzhou Fifth People's Hospital. The average age of onset was (46.8±6.6) years, and the average working age of dust exposure was (5.7±1.7) years.The main feature of high KV chest radiography is P/S shadow with strip shadow. CT imaging findings showed diffuse small nodules and ground glass shadows with band shadows. The lesions were mainly distributed in the upper lung, accompanied by pleural thickening, lymphadenopathy and calcification. The pulmonary function impairment was mainly mild restrictive ventilation disorder, and the bronchial mucosa longitudinal plica was the main manifestation under tracheoscopy. The age of silicosis of workers in artificial quartz stone production enterprises is younger, the working age of dust exposure is short, the lung function and bronchial mucosa have a certain degree of damage, and effective preventive measures should be taken in time.人造石英石粉尘暴露有可能引起相关性尘肺。2019年11月至2020年7月苏州市第五人民医院职业病科共诊治27例人造石英石生产企业相关性矽肺，患者平均发病年龄为（46.8±6.6）岁，平均接尘工龄为（5.7±1.7）年。高KV胸片以P/S影伴条索影为主，CT影像学表现均有弥漫性小结节影和磨玻璃影伴条索影，病灶分布以双上肺为主，伴有胸膜增厚、淋巴结肿大、钙化，肺功能损害以轻度限制性通气障碍为主，气管镜下表现以支气管黏膜纵行皱襞为主。人造石英石生产企业工人矽肺发病年龄较轻、接尘工龄短、肺功能、支气管黏膜有一定程度的损害，应及时采取有效的预防措施。.
