The baseline blood eosinophil count(EOS) related to therapeutic effect inhaled corticosteroids(ICS) acute exacerbation patients. level EOS may be affected by factors such as geography, race, etc. domestic work, actual reference data not consistent with recommended threshold value GOLD. Since there no uniform accurate epidemiological on COPD patients China, this review focuses research progress controversy areas inflammation, biomarkers, role guiding application ICS, discuss setting critical Chinese
