ABSTRACT
Objective:To observe the clinical effect of Bairui grain combined with ambroxol atomization inhalation treating acute attack of chronic bronchitis (wind heat attact the lung symptom). Methods:A total of 150 patients with acute attack of chronic bronchitis who were admitted in our hospital from July 2015 to July 2018 were randomly divided into control and intervention groups (75 each group) by the random number table method. The control group received ambroxol atomization inhalatio based on the regular western medicine treatment; the intervention group took Bairui grain orally based on control group. Both of the two groups were treated for 2 weeks. Before and after the treatment, to score the clinical symptoms and wind-heat attact the lung symptom. Use pulmonary function meter to detect the ratio of FEV1 to estimated value (FEV1%) and FEV1/FVC; use ELISA to detect serum and sputum levels of TNF-α and IL-6. Record the extinction time of the symptoms (cough, wheezing, sputum, lung rumble) and evaluate the clinical efficacy. Results:The total efficacy rate of intervention group was 98.6% (72/73), which was significantly higher than control group 88.9% (64/73) ( χ2=4.354, P=0.037). The symptoms (cough, wheezing, sputum, lung rumble) extinction time of intervention group were significantly less than those of the control group ( t values 5.331, 5.590, 5.841, 6.305, respectively, all Ps<0.01). After the treatment, scores of clinical symptoms (cough, wheeze, cough, cough) and symptoms of wind-heat attacking lung (cough, wheezing, fever, dry mouth, stuffy nose, runny nose) of intervention group were significantly lower than those of the control group ( t values 4.990, 4.431, 5.221, 5.004, 5.652, 5.190, 5.311, 5.793, 5.643, respectively, all Ps<0.01). After treatment, the FEV1% (52.51% ± 5.63% vs. 47.30% ± 5.21%, t=8.931) and FEV1/FVC (61.57 ± 6.44 vs. 56.87 ±5.82, t=8.251) were significantly higher than the control group ( P<0.01). The serum level of TNF-α, IL-6 ( t values 5.331, 4.908) and the level of TNF-α, IL-6 ( t values 6.001, 4.803) in sputum were significantly lower than those of the control group ( P<0.01). Conclusions:The Bairui grain combined with ambroxol atomization inhalation can decrease the inflammotory cytokine levels of the acute attack patients with chronic bronchitis (syndrome of wind-heat attacking lung symptome), improve clinical symptoms and enhance efficacy.
