OBJECTIVE: To investigate the effect of dongchong xiacao capsule on the airway inflammation of asthmatic patients and to explore the relevant mechanism of therapeutic effect of Dongchongxiacao capsule. METHOD: Sixty patients with moderate persistent asthma were randomized into the treatment group (n=30) and the control group (n=30). Inhaled corticosteroid and as-needed beta-agonist were used in the treatment group while this therapy plus dongchong xiacao capsule were used in the control group for two months. Serum IL-4, IFN-gamma, sICAM-1, MMP-9, IgG, IgE level were assessed at randomization and 2 months after randomization. RESULT: The serum level of IgE, sICAM-1, IL-4 and MMP-9 of the treatment group was lowered to a greater degree than that of the control group (P < 0.05 or P < 0.01 ). CONCLUSION: Dongchong xiacao capsule can reduce the serum markers of airway inflammation, which suggests this therapy bares the anti-inflammation effects probably through regulating the balance of TH1/TH2, inhibiting the activity of adherence molecule and reducing IgE production. It may also have the effect of reversing airway remodeling, which needs further research to determine.
