疾病的发生、发展与气候变化有密切关系。大风降温,严冬来临,这对患有慢性支气管炎(简称“老慢支”)的病人来说,更是提心吊胆,视过冬如过难关。慢性支气管炎是中老年的常见病、多发病。据统计,我国50岁以上的中老年人,“老慢支”的发病率大约在10%～20%左右,北方寒冷地区的发病率可高达40%以上,严重地影响他们的生活和健康。数九寒天,北风刺骨,寒冷的空气可使呼吸道局部温度降低,毛细血管收缩,血液减少,抵抗力下降。同时,寒冷还可导致支气管粘膜上皮的纤毛活动减慢,使呼吸道的细菌和病毒不易排出,加之外界入侵的细菌和病毒,非常容易导致慢性支气管炎的发作,而且易并发肺气肿,严重时还会出现肺心病。患“老慢支”的病人,最常
The occurrence and development of diseases are closely related to climate change. Gale cool, winter is approaching, which for patients with chronic bronchitis (referred to as “old chronic bronchitis”) is even more scary, depending on the winter as over the storm. Chronic bronchitis is a common disease in middle-aged and elderly. According to statistics, the incidence of “old chronic bronchitis” in our country is over 10% ~ 20% in middle and old people over 50 years of age. The incidence in cold area of northern China can be as high as 40% or above, seriously affecting their life and health. Number nine cold days, the north wind biting, cold air can lower the local respiratory tract temperature, capillary contraction, blood loss, decreased immunity. At the same time, the cold can also lead to bronchial mucosal epithelial cilia slowed down, so that respiratory bacteria and viruses are not easy to discharge, combined with outside invasion of bacteria and viruses, can easily lead to the onset of chronic bronchitis, and complicated by emphysema, severe Pulmonary heart disease will occur. Suffering from “old chronic bronchitis” patients, most often
