哮喘、肺气肿、肺心病、慢性气管炎是呼吸系统常见病,这些病不能说是医学上的“哥德巴赫猜想”,但也确实是医学上的一大难题。 这类呼吸系统疾病,是一种严重危害人类健康的常见病,尤以老年多见。世界卫生组织提供的资料表明,50岁以上的老人发病率和死亡率呈逐年上升趋势。日本、美国、加拿大等12个国家统计,气管炎、肺气肿和哮喘病成为老年人第五位死亡原因。 Asthma, emphysema, cor pulmonale and chronic bronchitis are common respiratory diseases. These diseases can not be said to be “Goldbach’s conjecture” in medicine, but they are indeed a major medical problem. Such respiratory diseases are a common disease that seriously endangers human health, especially in the elderly. Information provided by the World Health Organization shows that the morbidity and mortality rate of the elderly over the age of 50 has been increasing year by year. Japan, the United States, Canada and other 12 countries statistics, bronchitis, emphysema and asthma become the fifth leading cause of death in the elderly.
