Chinese Journal of Interventional Cardiology 1996;0(04):-
Objective To study the probability of evaluating myocardial tissue perfusion by corrected TIMI frame count (CTFC) after successful percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods Sixty-three patients with their first acute myocardial infarction (AMI) who accepted primary coronary intervention were recruited. All these patients got TIMI 3 grade flow. CTFC was measured after successful PCI in these patients. Wall Motion Score Index (WMSI) assessed by two-dimensional echocardiography before and one month after PCI and the correlation studied between CTFC and WMSI. Results According to CTFC the patients were divided into two groups. Improvement of WMSI in the TIMI 3 fast group was significantly greater than that of the TIMI 3 slow group. CTFC had a significant correlation with the change in WMSI. Elapsed time from the onset of symptoms to reperfusion in the TIMI slow group was significantly longer than that of the TIMI fast group. Conclusion CTFC is a quantitative, and reproducible index of coronary blood flow. Lower CTFC is associated with greater functional recovery and could supply evidence for additional adjunctive treatment.

This article was aimed to study the effect of pinellia combined with prunella vulgarisin of different ratios on the extraction yield of trigonellin and uracil, in order to investigate the changing disciplines and reasonable com-bination of Shuangxia Soup. A Welch Ultimate AQ-C18 column (4.6 mm×250 mm, 5 μm) was used in the study. The mobile phase, consisting of solvent A (water) and solvent B (acetonitrile) was programmed as a linear gradi-ent. The flow rate was 1.0 mL·min-1. And the detection wavelength was 265 nm. The column temperature was 25℃. HPLC was used in the determination of extraction yield of trigonellin and uracil for the comparison among different compatibilities. The results showed that the linearity was achieved in the range of 0.872-4.36 ng for trigonelline, and 10.8-50.4 ng for uracil. The average recoveries were 96.53%-101.48%, with RSD of 0.18%-4.26%. Com-pared with pinellia, the extraction yield of trigonelline was reduced and the extraction yield of uracil was increased after the compatibility. It was concluded that different compatibilities of Shuangxia Soup had effects on the extrac-tion yield of trigonelline and uracil. The best compatibility ratio still requires in-depth study.

To study the antiarrhythmic effect of the newly developed alpha/beta-blocker TJ0711, a variety of animal models of arrhythmia were induced by CaCl2, ouabain and ischemia/reperfusion. Glass microelectrode technique was used to observe action potentials of right ventricular papillary muscle of guinea pig. The onset time of arrhythmia induced by CaCl2 was significantly prolonged by TJ0711 at 0.75, 1.5 and 3 mg x kg(-1) doses. TJ0711 (1.5 and 3 mg x kg(-1)) can significantly shorten the ventricular tachycardia (VT) and ventricular fibrillation (VF) duration, the incidence of VF and mortality were significantly reduced. On ischemia-reperfusion-induced arrhythmic model, TJ0711 (0.25, 0.5, 1 and 2 mg x kg(-1)) can significantly reduce the ventricular premature contraction (PVC), VT, VF incidence, mortality, arrhythmia score with a dose-dependent manner. At the same time, rats serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities decreased significantly by TJ0711 (1 and 2 mg x kg(-1)). Ouabain could cause arrhythmia in guinea pigs, when TJ0711 (0.375, 0.75, 1.5 and 3 mg x kg(-1)) was given, the doses of ouabain inducing a variety of arrhythmia PVC, VT, VF, cardiac arrest (CA) were significantly increased with a dose-dependent manner. In the TJ0711 0.1-30 micromol x L(-1) concentration range, guinea pig right ventricular papillary muscle action potential RP (rest potential), APA (action potential amplitude) and V(max) (maximum velocity of depolarization) were not significantly affected. APD20, APD50 and APD90 had a shortening trend but no statistical difference with the increase of TJ0711 concentration. TJ0711 has antiarrhythmic effect on the sympathetic nerve excitement and myocardial cell high calcium animal arrhythmia model. Myocardial action potential zero phase conduction velocity and resting membrane potential were not inhibited by TJ0711. APD20, APD50 and APD90 were shortened by TJ0711 at high concentration. Its antiarrhythmic action mechanism may be besides the action of blocking beta1 receptor, may also have a strong selective blocking action on alpha1 receptor and reducing intracellular calcium concentration.
