ABSTRACT
Objective:To investigate the efficacy of Yanghe Pingchuan Decoction in the treatment of chronic obstructive pulmonary disease (COPD) with syndrome of kidney deficiency and phlegm in the acute exacerbation stage.Methods:A total of 86 patients meeting the standard with acute exacerbation of COPD who were admitted to Haikou Hospital of TCM from May 2019 to July 2021 were selected and divided into an observation group and a control group by random number table method, with 43 cases in each group. The patients in the control group were treated with conventional Western medicine, and the patients in the experimental group were treated with Yanghe Pingchuan Decoction on the basis of the treatment in the control group. Both groups took 14 days of treatment. Scoring of TCM symptom of both groups before and after treatment was conducted. The serum levels of CRP, TNF-α and IL-6 were detected by ELISA, and the ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) and the percentage of FEV1 to predicted value (FEV1%) were detected by automatic pulmonary function tester. Clinical efficacy was evaluated.Results:The observed total effective rate was 90.70% (39/43) in the observation group, which was significantly higher than 72.09% (31/43) in the control group, with statistical significance ( χ2=4.91, P<0.05). After treatment, the symptom scores of cough and expectoration, wheezing, shortness of breath, poor appetite, sweating and cold limbs in the observation group were significantly lower than those in the control group ( t values were 10.21, 11.30, 15.77, 13.87, 8.73, respectively, all Ps<0.01); the levels of CRP and TNF-α，IL-6 in the observation group were significantly lower than those in the control group ( t values were 22.43, 18.21, 20.90, respectively, all Ps<0.01); the levels of FEV1/FVC (62.58±5.23 vs. 58.47±11.61, t=2.12), FEV1 (63.79±1.47 vs. 60.17±10.94, t=2.15) in the observation group were significantly higher than those in the control group ( P<0.05). Conclusion:Yanghe Pingchuan Decoction can effectively improve the pulmonary function of patients with acute exacerbation of COPD, relieve clinical symptoms, reduce the levels of serum CRP, TNF-α and IL-6, and improve the efficacy.
