Methods： One hundred patients with ACS after successful PCI were randomly assigned to a Western medicine （WM） treatment group （WMG） and a combined treatment group （CMG） treated by Chinese herbs for supplementing qi, nourishing yin and activating blood circulation, besides Western medicine treatment, with 50 cases in each group. Both treatment courses were 6 months. The follow- up was scheduled at baseline, 6 months and 1 year after PCI, and New York Heart Association （NYHA） functional class, Chinese medicine （CM） symptom scores, blood stasis syndrome scores, and major adverse cardiovascular events （MACE） were observed, serum levels of N-terminal pro-brain natriuretic peptide （NT-proBNP） and hyper-sensitivity C-reactive protein （Hs-CRP） were measured, an echocardiogram was conducted to examine left ventricular ejection fraction （LVEF）, left ventricular end-diastolic volume （LVEDV）, left ventricular end-systolic volume （LVESV）, inter-ventricular septal thickness （IVST）, left ventricular posterior wall thickness （LVPWT）, and ventricular wall motion index （VWMI）. Results： Compared with the baseline, LVEF significantly increased （P〈0.01）, and CM symptom scores, blood stasis syndrome scores, VWMI, LVEDV, LVESV, NT-proBNP, and Hs-CRP all decreased （P〈0.01） in both groups at 6 months and at 1 year after PCI. There were no significant differences in all the above parameters at 1 year vs those at 6 months after PCI （P〉0.05）. VWMI, LVEDV, LVESV, NT-proBNP, Hs-CRP, LVEF, and CM symptom and blood stasis syndrome scores were all improved obviously in CMG than those in WMG （P〈0.05 or P〈0.01） at 6 months and at 1 year after PCI. There were no significant differences in NYHA functional class between CMG and WMG at different follow-up timepoints; it was notable that P value was 0.054 when comparing the cases of NYHA functional class between the two groups at 1-year follow-up. During the 1-year follow-up, 3 MACE and 11 MACE occurred in CMG and WMG, respectively; the MACE rate in CMG was lower than that in WMG （6% vs 22%, P〈0.05）. Conclusion： Chinese herbs for supplementing qi, nourishing yin and activating blood circulation could improve heart function, reduce the CM symptom scores and blood stasis syndrome scores, and decrease the incidence of MACE in patients with ACS after successful PCI.展开更多

The acute myocardial infarction (AMI) model was established by ligating the left anterior descending (LAD) coronary artery, then the model rats were randomly divided into the model group, the Metoprolol group, the replenishing qi nourishing yin (RN) group, the activating blood circulation (AB) group, and the replenishing qi, nourishing yin and activating blood circulation (RA) group. In addition, the normal group and the sham group were set up. The rats of medication groups were administered by intragastric gavage with corresponding drugs on the second day after operations, and the rats of the normal group and the sham group were given normal saline as the same time.Then the ischemic hearts were harvested on the 8th day after operation. The myocardial pathomorphological changes were observed under a light microscope. The mRNA changes of target genes such as COX5a and ATP5e were detected using Realtime fluorescence quantitative PCR (QPCR), and the activities of related enzymes were detected by colorimetric assay. The main results were as follows: the histological changes were observed by HE staining, and cardiocyte swelling, inflammatory cell infiltration and cytolysis were showed in regional ischemic myocardium of the model group, while the pathomorphological changes in all medication groups did not show obvious changes. Two genes related to energy metabolism, COX5a and ATP5e, were selected as the target genes which were downregulated at the mRNA level in the medication groups. The activities of correlative functional enzymes also decreased in the RA group compared to that in the model group accordingly (P<0.05). The results indicated that the abnormal expression of genes involved in energy metabolism pathways could be one of the molecular mechanisms of AMI. The compatibility of Chinese herbs capable of replenishing qi, nourishing yin and activating blood circulation affects the expression of energyrelative gene COX5a, ATP5e, which is probably the mechanism of myocardial preservation, and is more effective than single herb of replenishing qi and nourishing yin or activating blood circulation.展开更多
