About me
Medical doctor. Since 2002, I have been working in the Respiratory Department of Xiangya Hospital, accumulating rich clinical experience in the diagnosis and treatment of numerous difficult and critically ill patients. This includes refractory cough, chronic bronchitis, emphysema, chronic obstructive pulmonary disease (COPD), asthma, lung cancer, pulmonary tuberculosis, interstitial lung disease, and refractory pneumothorax. I serve as a member of the Respiratory Physiology and Pulmonary Function Committee of the Chinese Medical Doctor Association, the Science Popularization Committee of the Respiratory Rehabilitation Committee of the Chinese Rehabilitation Medicine Association, and the Health Management Committee of the Hunan Medical Association.

How is pneumoconiosis caused?
Pneumoconiosis is a systemic disease characterized by diffuse fibrotic scarring of lung tissue. It is caused by the long-term inhalation of industrial dust and dust during occupational activities, which accumulates in the lungs. Once pneumoconiosis occurs, it is irreversible and incurable for life, with a high mortality rate of up to 22%. So, who is more likely to develop pneumoconiosis? The main occupations include: First, mining activities, including coal mining, metal mining, and non-metal mining. These activities produce a large amount of dust that, when inhaled into the lungs, can cause pneumoconiosis. Second, mechanical manufacturing, specifically during the manufacturing process of metal castings. Activities such as sand mixing for casting and sand molding can lead to pneumoconiosis, particularly among welders who dominate this industry. Third, metal smelting, involving ore loading and unloading, steel casting, and alumina sintering. The primary occupations exposed include sintered pellet raw material workers, sintering workers, and blast furnace operators, all of whom come into contact with large amounts of dust. Fourth, the construction industry, for example, with materials resistant to fire such as quartz sand, glass, stone, and cement production, as well as asbestos mining. Workers in these industries are exposed to large amounts of dust. In China, the top three types of pneumoconiosis are silicosis, coal worker's pneumoconiosis, and graphite pneumoconiosis, along with those working in jade processing and welder's pneumoconiosis, which are relatively common.
