ABSTRACT

Objective To investigate the effect of Zhubei Dingchuan pill on clinical symptoms and inflammatory mediators in serum and induced sputum of patients with chronic bronchitis. Methods 80 cases of patients with chronic bronchitis treated in the Department of Respiration in our hospital from January 2016 to January 2017 were selected and were randomly divided into the control group and the observation group, with 40 cases in each group. The control group was given symptomatic support treatment and the observation group was additionally given Zhubei Dingchuan pills on the basis of the control group. The changes of inflammatory mediators levels in serum and induced sputum were measured before and after treatment between the two groups, and the clinical efficacy was observed in the two groups. Results After treatment, the levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and high-sensitivity C reactive protein (hs-CRP) in serum or induced sputum in the observation group were significantly lower than those in the control group (P<0.05). The effective rate of treatment in the observation group was significantly higher than that in the control group (95.0％ vs. 82.5％) (P<0.05). Conclusion Zhubei Dingchuan pill can effectively relieve the clinical symptoms in patients with chronic bronchitis, and its pharmacological mechanism is related to the decrease of levels serum and airway inflammatory mediators.
