Abstract:Objective To study the effect of Corbrin capsule on airway function and serum airway remodeling molecules in patients with stable COPD. Methods During January 2016 to December 2017, 80 cases of stable COPD patients undergoing treatment in our hospital were selected as research subjects, and were divided into control group (n = 40) and Corbrin capsule group (n = 40). Patients in control group were treated with routine COPD treatment for 8 weeks, and those in Corbrin capsule group were treated with Corbrin capsule for 8 weeks on the basis of routine treatment. The difference of airway function parameters and serum contents of airway remodeling molecule between two groups before and 8 weeks after treatment were compared. Results Levels of airway function parameters such as FEV1, FEV1/FVC, MEF50, MEF25-75 and MEF25 in Corbrin capsule group were higher than those in control group (P < 0.05); serum contents of TGF-β1, NOX4, NF-κB and MMP-9 in Corbrin capsule group were lower than those in control group (P < 0.05). Conclusions Adding Corbrin capsules to stable COPD patients on the basis of routine treatment can effectively optimize airway function and inhibit the expression of airway remodeling molecule.
