Objective To investigate the treatment of the Soviet Union after the Su Huang Capsule respiratory infection cough cough ef-ficacy and safety evaluation. Methods 120 cases of upper respiratory tract infection cough patients according to the random number table will be included in this group were randomly divided into treatment group ( n = 60) and control group ( n = 60) . The treatment group received capsules Su Huang cough treatment, the control group received dextromethorphan oral therapy, were treated for 10 d. Results The overall response rate (95. 00% ) was significantly higher (81. 67% ), and has a significant ( P < 0. 05) . The treatment group cough scores were significantly lower than the control group, and has a significant ( P < 0. 05) . The treatment group scores day-time and nighttime cough cough symptom score was significantly lower than the control group, and both have a significant ( P < 0. 05). The EOS, NEU, LYM number has a significant ( P < 0. 05) . No obvious adverse reactions during treatment groups. Conclusion Su Huang cough Capsule respiratory infection after the treatment effect is significant, safe and reliable, has important clinical significance, worthy of further applications.%目的：探讨苏黄止咳胶囊联合早期抗炎防治上呼吸道感染后反复咳嗽的临床疗效。方法将120例患者随机均分为对照组和观察组。两组患者均给予抗病毒或抗菌基础治疗，对照组加用右美沙芬口服液，观察组加用苏黄止咳胶囊，两组疗程均为10 d。结果观察组总有效率为95.00%，显著高于对照组的81.67%（ P <0.05）。治疗后，两组患者咳嗽评分均较治疗前降低，且观察组患者降幅大于对照组（ P <0.05）；观察组患者咳嗽持续时间及再次发作间隔时间均短于对照组（ P <0.05）；两组患者外周血嗜酸性粒细胞（EOS）、中性粒细胞（NEU）和淋巴细胞（LYM）计数均降低，且观察组患者降幅大于对照组（ P <0.05）。治疗期间两组患者均未发生明显不良反应。结论苏黄止咳胶囊治疗上呼吸道感染后反复咳嗽临床疗效好，可通过改善患者免疫功能及气道高反应性降低症状持续时间、减少复发频率，且安全性高，值得临床推广。
