Clinical Observation of Huagai Pingchuan Decoction Combined with Seretide in the Treatment of Asthma

Objective:To study the clinical effect of the Huagai Pingchuan decoction combined with Seretide in the treatment of asthma.Methods:138 cases of asthma patients in our hospital were separated into the control group and the experimental group.The control group was given Seretide alone,while the experimental group was treated with Huagai Pingchuan decoction combined with Seretide.Results:After treatment,the wheezing symptoms remission time of the experimental group was shorter than control group,the performance of serum inflammatory factors and lung function indexes were better than control group,P<0.05 with significant difference.Conclusion:Huagai Pingchuan decoction combined with Seretide is more effec-tive in the treatment of asthma.

Functional mechanism of Pingchuanning Decoction on adjustment of clara cell secretory protein in airway remodeling of asthmatic rats

OBJECTIVE:To study the functional mechanism of Pingchuanning Decoction in treatment of airway remodeling in asthmatic rats.METHODS:Eighty healthy Wistar male rats were randomized into eight groups(n=10 rats each):Normal group,Asthma model group,Dexamethasone group,Guilong Kechuanning group,Xiaoqinglong Decoction group,and Pingchuanning Decoction low-,middle-,and high-dose groups.The rats of all but the Normal group were made into asthma models through intraperitoneal injection and aerosol inhalation of ovalbumin.All treatments were administered at the first stimulation of asthma onset(third week of modeling),and the rats were killed after stimulating asthma attacks for 4 weeks.The general conditions of rats and pathomorphological changes of the lung tissues were observed.The expression of nerve growth factor(NGF) of the lung tissues was measured with immunohistochemical methods,and the content of Clara cell secretory protein(CCSP) mRNA was determined with RT-PCR.RESULTS:Compared with the Normal group,the contents of NGF and CCSP mRNA in the lung tissues of the Model group were significantly changed(P<0.01).Compared with the Model group,the indices of Pingchuanning Decoction and other treatment groups were improved to some extent(P<0.05 or P<0.01).CONCLUSIONS:Pathological changes of airway inflammation and remodeling were present in these rat asthma models.Pingchuanning Decoction had an intervention effect on these experimental models.Its functional mechanism may be related to multiple factors,including alleviation of airway inflammation,relief of bronchial smooth muscle spasm,and inhibition of airway remodeling.
