Chronic bronchitis is a common non-specific respiratory system disease. With the entry of an aging society and the increase of chronic bronchitis risk factors (smoking, environmental pollution, etc.), the actual number of patients with chronic bronchitis will increase. Finding safe and effective drugs is of great significance for the prevention and treatment of chronic bronchitis. When screening drugs for the treatment of chronic bronchitis, it is usually necessary to establish an animal model of chronic bronchitis. Cigarette smoking can establish an animal model similar to human chronic bronchitis, which has good application value.
