RESUMEN
Objective To observe the clinical effect of Shumu-Yuntu-Zhike decoction with conventional treatment for the Gastroesophageal Reflux Cough (GERC).Methods A total of 64 patients with GERC were randomly divided into the conventional treatment group and the combined treatment group, 32 in each. The conventional treatment group took the Rabeprazole capsule and Mosapride Citrate Tablets, and the combined treatment group received the traditional prescription of Shumu-Yuntu-Zhike decoction on the basis of the conventional therapy. Two groups were treated for 8 weeks and evaluated the effect with the Visual analogue scale (VAS), Reflux diagnostic questionnaire (RDQ) and Chronic cough impact questionnaire (CCIQ) before and after 4 and 8 weeks' treatment.Results After 4 week treatment, the VAS (4.47 ± 1.32vs. 6.22 ± 1.34;t=-5.859,P<0.01), CCIQ (32.60 ± 5.83vs. 47.32 ± 5.56,t=-11.548,P<0.01) in the combined treatment group decreased significantly than the conventional group, but the RDQ (13.62 ± 2.89vs. 13.67 ± 2.77;t=-0.079, P=0.937) showed no significant difference between the two groups. After 8 weeks' treatment. After 8 week treatment, the VAS (2.57 ± 1.69vs. 4.55 ± 2.06;t=-4.676,P<0.01), CCIQ (12.47 ± 3.41vs. 23.47 ± 3.55;t=-14.126,P<0.01) in the combined treatment group decreased significantly, but the RDQ (9.18 ± 2.77vs. 9.3 ± 2.43,t=-0.202,P=0.841) showed no significant difference between the two groups. After the treatment, the total effective rate of combined treatment group was 90.6% (29/32), while the control group was 68.7% (22/32). There was significant difference between the two groups (χ2=4.730,P=0.030).Conclusions The therapy of Shumu-Yuntu-Zhike decoction combined with conventional therapy can relieve the symptom of gastroesophageal reflux cough.
