ObjectiveTo investigate the impact of integrated Chinese and western medicine on lung function in patients with cough variant asthma. Methods76 patients with cough variant asthma between January 2010 and January 2013 in our hospital were randomly divided into observation group and control group, with 38 cases in each. The control group were treated with theophylline release tablets (0.1g, 2 times a day, p.o), ketotifen(1 mg, 2 times a day, p.o), and seretide ［(salmeterol xinafoate and fluticasone propionate inhalation powder, 50μg: 500μg), 2 times a day, inhalation］. The observation group were treated with Chinese medicine based on western medicine. Curative effects were compared between the two groups, while lung function(indicators FEVl, FEVl% predicted value, FEVl/FVC) in two groups were compared before and after treatment. ResultsTotal effective rate of observation group and control group was 86.8% and 68.4%, respectively. The clinical curative effect in the observation group was significantly better than that in the control group (P=0.020). There were no significant difference in FEVl, FEVl% predicted value, and FEVl/FVC between the two groups before treatment(P＞0.05).After treatment, all indexes in the two groups were higher than those before treatment, and FEVl% predicted value and FEVl/FVC in the observation group were higher than that in the control group(P＜0.05). ConclusionIntegrated Chinese medicine and western medicine can increase therapeutic effect and improve lung function in patients cough variant asthma, which is worthy to be widely employed.
