支气管哮喘不论在成人还是在儿童都是一种常见的疾病。哮喘是气道的慢性炎症性疾病,许多细胞尤其是肥大细胞、嗜酸性粒细胞和淋巴细胞都参与了其发病过程。患者出现喘息、呼吸困难、胸闷和咳嗽。这些症状主要发生在夜间或凌晨,常与气道阻塞同时发生,可自发或经治疗后缓解。气道炎症可引起气道对一系列刺激物的反应性增高。 支气管哮喘的诊断标准包括下面3个重要的观点,即气道阻塞的可逆性、气道高反应性和炎症。因此,对呼吸功能、气道反应性和炎症的客观检查是支气管哮喘诊断的最重要措施。
Bronchial asthma is a common disease in both adults and children. Asthma is a chronic inflammatory disease of the airways, and many cells, especially mast cells, eosinophils and lymphocytes, are involved in the pathogenesis. Patients have wheezing, difficulty breathing, chest tightness and coughing. These symptoms occur mainly at night or early morning, often with airway obstruction occurs simultaneously, spontaneously or after treatment to ease. Airway inflammation can cause increased reactivity of the airways to a range of stimuli. The diagnostic criteria for bronchial asthma include the following three important points, namely the reversibility of airway obstruction, airway hyperresponsiveness and inflammation. Therefore, the objective examination of respiratory function, airway responsiveness and inflammation is the most important measure for the diagnosis of bronchial asthma.
