Clinical Research On Deficincy Of Pulmonary And Renal Qi Of Chronic Cor Pulmonale Treated With Bufeiyishen Decoction

The abnormality of lung structure and lung function induced by the extensive chronic pathological changes of pulmonary artery, pulmonary organization and thorax led up to the increase of pulmonary vascular resistences,which caused pulmonary hypertension, pulmonary hypertension was in duced to enlarge the right ventricle, with or without right ventricular failure. This kind of disease above is called chronic cor pulmonale, which is one kind of common ailment in the respiratory system. The falling ill rate of pulmonary heart disease is area divergence. In Northern area the falling ill rate is more than the southern area, the higher age gets, the higher fallng ill rate is. CCP threatens human life seriously. The key to preventing the development of CCP lies in prophylaxis and treatment of catabasis. Traditional Chinese medicine is superior to western medicine in treating CCP of catabasis. This study was conducted to observe the clinical effect of treatment of deficiency of pulmonary and renal Qi of catabasis of CCP with Bu fei Yi shen decoction.We dividied 100 pationts into two groups randomly. The 50 cases of the treated group were treated with "Bu fei Yi shen decoction", while only routine treatment for control group. Symptoms, signs were observed before and after the treatment. The results indicated that the obvious effective rate(40%) was signiticantly higher than that in control group (20%). Thetotal response rate in treated group (96%) was significantly higher than that in control group(54%). There was significant difference in the total effective rate between both groups (p < 0.05). The Improvement of symptoms in treated group were much better than those of the control group (p < 0.05). Bu fei Yi shen decoction also can build up immunity ability of human body, and decrease acute breakout of CCP without side effect.We think the main mechainism of CCP relieving course is deficiency of pulmonary and renal Qi. Invigorating the lung, nourishing the kidney and preventing asthma were the main ways to CCP. The was very effective of Bu fei Yi shen decoction to the deficiency of pulmonary and renal Qi of relieving course of CCP.Bu fei Yi shen decoction is an effective medicine to the prophylaxis and treatment of CCP.
