Asthma is a respiratory disease and is one of the three killers that threaten human health. According to a 2000 survey, the overall prevalence of asthma in our country was 2% to 5% with a mortality rate of 36.7 / 100 000, ranking first in the world. Bronchial asthma (hereinafter referred to as asthma) is a type of inflammatory cell, airway inflammatory cells, structural cells (eg, eosinophils, mast cells, T lymphocytes, neutrophils, smooth muscle cells, airway epithelial cells, etc. ) And cellular components involved in chronic airway inflammatory disease.
