Methods: One hundred and twenty-four patients with acute viral myocarditis were randomized into the treated group (SMG, n = 64) and the control group(CG, n = 60 ). Such myo-cardial nutrient medicine as ATP, CoA , Vit-C, were given to both groups. And to the treated group, 40 ml of Shengmai Injection per day was given intravenously for 2 weeks, which was followed by oral intake of Shengmai granule, one package three times daily for another 2 weeks in total. The same anti-arrhythmia agents were applied to both groups, and no fructose-1, 6-diphosphate (FDP) for either. Semi-quantitative scoring method was adopted to observe such symptoms as chest stuffiness, palpitation and chest pain before treatment and four weeks after treatment. Meanwhile, EGG, dynamic ECG by Holter monitor, left ventricular end-diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF), serum neutralizing antibody of virus Coxsackie B, cardiac troponin I (cTnl) and cardiac troponin T (cTnT) were examined. Results: (1) Compared with the control group, more significant improvement was got in SMG in respects of chest stuffiness, palpitation, chest pain and arrhythmia (P<0.05 or P<0.01). (2) Negative converting rates of cTnl ,cTnT in the two groups were 59.46% vs35.48%, 68.75% vs42.31% respectively ( P<0. 05). (3) LVEDD before and after treatment in SMG was 52. 44 ± 3. 40 mm and 48. 81 ± 2. 23mm respectively, while that in the control group was 52. 31 ± 3. 74 mm and 49. 92 ± 2. 67mm respectively; LVEF before and after treatment in SMG was 60.67 ± 4. 62 % and 65. 02 ± 4. 16 % respectively, while that in the control group was 60.91 ± 4. 26 % and 63. 67 ± 3.17 % . There was obvious improvement in the two parameters in both groups, but the improvement in SMG was superior to that in the control group ( P<0. 05). Conclusion: SMP shows a good effect in improving clinical symptoms and signs, heart function, abnormal ECG and inflammatory injury indexes in patients with acute viral myocarditis.展开更多

Methods: The model of Qi-Yang exhaustion and Qi-Yin exhaustion were made with hemorrhagic rats and heat-stressed rats respectively. The effect of Shenfu decoction (SFD) and Shengmai powder (SMP) on plasma glucocorticoid (GC) and its receptor (GcR) in hepatic cytosol of the models were measured respectively. Results: The activity of GcR decreased in both models, while their blood level of GC increased markedly. SFD and SMP showed no regulating effect on blood GC, but displayed obvious up-regulation on GcR level in both models. Conclusion: SFD and SMP could up-regulate the activity of GcR in Qi-Yang and Qi-Ying exhaustion models.展开更多
