Echocardiography was employed to evaluate cardiac function and the degree of myocardial ischemia, 2-DE and matrix-assisted laser desorption/ionization-time of flight mass spectrometry （MALDI-TOF-MS） were used to carry out proteomics research on animals. Enzyme-linked immunosorbent assay was applied to identify the relevant differential proteins on chronic myocardial ischemia with qi deficiency and blood stasis syndrome. Results： The preliminary study found that at the 12th week, chronic myocardial ischemia with qi deficiency and blood stasis syndrome model was established stably. Compared with the sham group, there were 8 different proteins down-regulated, 22 proteins up-regulated significantly. After validated by MALDI- TOF-MS/MS, 11 protein spots were identified. Distinct proteins were mainly associated with energy metabolism and myocardial structural injury, including isocitrate dehydrogenase 3 （NAD＋） alpha, NADH dehydrogenase （NAD） Fe-S protein 1, chain A （crystal structure of aidose reductase by binding domain reveals a new Nadph）, heat shock protein 27 （HSP27）, oxidoreductase （NAD-binding protein）, antioxidant protein isoform, cardiac troponin T （cTnT）, myosin （myosin light polypeptide）, cardiac alpha tropomyosin, apolipoprotein A- I and albumin. Conclusion： Down-regulated energy metabolism disorder mediated by NADH respiratory chain and myocardial injury may be the pathogenesis of myocardial ischemia with qi deficiency and blood stasis syndrome. These proteins may be the potential diagnostic marker（s） for qi deficiency and blood stasis syndrome, finally provided new clues for new therapeutic drug target of Chinese medicine

温和灸联合药物治疗扩张型心肌病气虚血瘀证疗效观察及对血清POSTN、cMyBP-C的影响

目的观察温和灸联合药物治疗扩张型心肌病(dilated cardiomyopathy,DCM)气虚血瘀证的临床疗效及对血清骨膜蛋白(periostin,POSTN)、心肌肌球蛋白结合蛋白-C(cardiac myosin binding protein-C,cMyBP-C)的影响。方法将80例DCM气虚血瘀证患者随机分为对照组和观察组,每组40例。对照组予常规药物治疗,观察组在此基础上予温和灸。比较两组治疗前后血清N端脑钠肽前体(N-terminal pro-brain natriuretic peptide,NT-proBNP)水平、6 min步行距离、明尼苏达心力衰竭生活质量量表(Minnesota living with heart failure questionnaire,MLWHFQ)评分、左室舒张末径(left ventricular end-diastolic dimension,LVEDD)、左室射血分数(left ventricular ejection fraction,LVEF)、左室短轴缩短率(fractional shortening,FS)及血清POSTN和c My BP-C水平,并比较两组临床疗效。结果观察组总有效率高于对照组(P<0.05)。治疗后,两组血清NT-proBNP水平均降低(P<0.05),6 min步行距离均增加(P<0.05),MLWHFQ评分均降低(P<0.05);且观察组均优于对照组(P<0.05)。治疗后,对照组LVEDD和FS无明显变化(P>0.05),LVEF升高(P<0.05);观察组LVEDD降低(P<0.05),LVEF和FS升高(P<0.05),且均优于对照组(P<0.05)。治疗后,对照组血清POSTN和cMyBP-C水平无明显变化(P>0.05);观察组血清POSTN和c MyBP-C水平均降低(P<0.05),且低于对照组(P<0.05)。结论温和灸联合药物治疗扩张型心肌病气虚血瘀证的疗效显著,可改善患者心脏功能,提升运动耐力及生活质量,延缓心室重构,这可能与其降低血清POSTN和c My BP-C水平有关。
