Bronchial asthma (asthma for short) is a chronic inflammatory disease of the airways involving multiple cells, including inflammatory and structural cells of the airways (e.g., eosinophils, mast cells, T lymphocytes, neutrophils, smooth muscle cells, airway epithelial cells, etc.) and cellular components.Chronic inflammation leads to airway hyperresponsiveness, usually with widespread variable and reversible airflow limitation, and causes recurrent episodes of wheezing The symptoms include shortness of breath, chest tightness or coughing, which often flares up and worsens at night and/or early in the morning. Most patients experience relief on their own or with treatment. Because asthma is a chronic inflammatory airway disease with recurrent and variable features, long-term clinical treatment is required. Regular application of anti-inflammatory drugs can result in good control of the disease in nearly 80% of patients, and the main therapeutic goal is to achieve and maintain asthma control.
