After treating, the treatment group in the First Affiliated Hospital of Henan College of Traditional Chinese Medicine showed a significant improvement in cough degree and cough frequency which is better than the control group (p<0.05). Symptoms as itchy throat, shortness of breath, expectoration are similar (p>0.05) between the two groups. After treating, the treatment group in the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine has a improvement in symptoms of cough degree, cough frequency which are better than the control group (p<0.05), while there is a similarity in itchy throat, shortness of breath, and expectoration (p>0.05) between the two groups; And the treatment group in Guangdong Provincial Hospital of Traditional Chinese Medicine has a significant improvement in the degree of cough which is better than the control group (p<0.05). Symptoms as cough frequency, itchy throat, shortness of breath, expectoration are similar (p>0.05) between the two groups.Comparison of the efficacy of the overall before and after treatment:For the China-Japan Friendship Hospital,the First Affiliated Hospital of Henan College of Traditional Chinese Medicine, the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine and the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, comparison of the efficacy rate of the four hospital show that the treatment group has better clinical efficacy rate than the control group after the treatment, X2cmh=44.5511, P <0.0001.
