RESUMO
Objective:To explore the clinical efficacy of modified Jinshui Liujunjian combined with salmeterol/fluticasone on senile asthma on persistent stage and its effect on vascular endothelial growth factor (VEGF) and transforming growth factor-β1 (TGF-β1) in serum. Method:The 100 cases of senile asthma who met inclusion criteria were selected and divided into two equal groups by random number table:the control group and the treatment group. Patients of the two groups were given oxygen therapy,phlegm reduction,infection control and salmeterol/fluticasone 50 μg·(500 μg)-1. Patients in control group were given sustained release capsule of theophylline in addition to the above therapy,while patients in treatment group were given modified Jinshui Liujunjian. The course of treatment was 8 weeks. The therapeutic effectiveness of traditional Chinese medicine (TCM) syndrome between two groups was observed. Asthma control test (ACT) scores at four different time points(before and after treatment,3, 6 months after treatment),pulmonary function,the levels of VEGF and TGF-β1 in serum before and after treatment between two groups were also observed. The pharmic safety during treatment was evaluated. Result:The total effective rate of treatment group was significantly higher than that of control group(PPβ1 in serum in treatment group were significantly lowered after treatment(P1%), and the percentage of forced expiratory volume in the first second and its forced vital capacity (FEV1/FVC) were significantly higher(PPConclusion:Modified Jinshui Liujunjian combined with Salmeterol/Fluticasone was more effective than Sustained release capsule of theophylline combined with Salmeterol/Fluticasone in improving the clinical efficacy and pulmonary function of senile asthma on the persistent stage. Its mechanism of action is probable correlated with the reduction of levels of VEGF and TGF-β1 in serum.
RESUMO
Objective To investigate the changes of airway resistance before and after Bronchial Diulation Test in patients with senile asthma and the effect of age on the degree of airway resistance. Methods A total of 29 (> 60 years)senile asthma patients and 21 younger( 60 years)and the group of healthy control(age < 60 years ). Each index of the airway resistance has a very good correlation with FEV1%,with the highest degree of relation is X5%. Conclusion The airway resistance of senile asthmatic patients was significantly improved after diuslation test and these indexes IOS would be valuable in evaluating the changes of airway resistance of senile asthma.
