The results show that it is much reasonable to evaluate pharmacodynamics of traditional Chinese drug which treat thoracic obstruction cardialgia in the acute myocardial infarction models with blood stasis in rats.

大鼠"血瘀证"下急性心肌梗死模型与单纯急性心肌梗死模型在心电图变化上存在明显差异，在血流动力学各项指标上无明显差异，提示采用"血瘀证"下急性心肌梗死模型来评价治疗胸痹心痛中药的药效学更为合理。关键词：血瘀；心肌梗死；大鼠 Wistar；血流动力学；心电描记术

Acute myocardial infarction is a common cause for sudden and unexpected death. However, it is difficult to detect the myocardial changes in medico-legal practice with traditional macroscopic examination or routine histological stains when the sudden death occurs in the hyper-acute phase of infarction (＜3h).

急性心肌梗死是引起猝死的常见原因，然而，在法医实践中，对于心肌梗死的超急性期（＜3小时）发生死亡的心脏用传统的肉眼观察或常规组织学检查的方法很难发现心肌的形态学改变从而提供客观的诊断依据。

Based on the latest achievements of the mechanism of peradaptation to myocardium ischemia and pharmacodic preadaptation up to date, observations were made on 80 patients of acute myocardial infarction to assess the enzymatic dynamics of myocardium, symptoms after myocardial infarction occurred like cardiac rhythm abnormality, anginapectoris, heart failure, cardiogenic shock, reinfarct and the mortality in the hospital. The results indicated that peradaptation to myocardium ischemia is of significance in protecting myocardium, reducing the areas of infarction, abating the cardiac insufficiency after infarction and reducing the abnormality of heart rhythm and significantly ameliorating the prognosis.

本研究结合现代医学对心肌缺血预适应机制及药理性预适应作用的最新研究成果和动向，通过临床观察80例急性心肌梗死患者的心肌酶学变化，心律失常、梗死后心绞痛、心力衰竭、心源性休克、再次梗死等心肌梗死后并发症和住院病死率，证实缺血预适应具有保护心肌，缩小梗死范围，减轻梗死后心功能不全及减少心律失常的作用，可明显改善心肌梗死病人的预后。

Diabetes mellitus have a lesser ability to develop collateral vessels after acute myocardial infarction. It mainly affects the process of arteriogenesis, but not angiogenesis. This effect may be partly due to the lower expression of bFGF.

糖尿病主要是通过影响动脉生成阻碍心肌梗死后冠状动脉侧支循环的形成，梗死区和梗死周边区的血管内皮细胞、心肌细胞bFGF表达减少参与了该过程。

The cyclic variation of integrated backscatter and echo intensity of three different myocardial regions perfused by left anterior descending coronary artery, left circumflex coronary artery and right coronary artery (on the frozen frame of parasternal short-axis image,those position were approximately at the 12, 4 and 8 o'clock direction to the center of the left ventricle, respectively) were measured with HP-5500 ultrasonic system and DFY ultrasonographic quantitative analysis system.

在35例急性心肌梗死患者发病2周内，用HP-5500型超声诊断仪和DFY型超声图像定量分析诊断仪，在胸骨旁左室乳头肌短轴切面，分别测量冠状动脉左前降支、左回旋支和右冠状动脉支配区域心肌组织(分别相当于左室乳头肌短轴切面上12、4、8点的位置)的IB和EI心动周期变化幅度值，以CVIB和CVEI值≤同一切面三个不同部位中最高值的1/2作为诊断心肌梗死的标准，部分病例与冠脉造影结果对比。

Methods: To create the model of myocardial infarction, to detect the serum SOD and LPO of the MI rats by the pyrogallic acid self-oxidation and detect myocardium tissue ROS of the MI rats by flow cytometry.

建立IR心肌梗死动物模型，采用邻苯三酚自氧化法检测梗死大鼠血清超氧化物歧化酶、过氧化脂质；运用流式细胞术检测梗死大鼠心肌组织中性粒细胞活性氧。

Methods: a comprehensive analysis of 20 cases with acute left ventricular failure as the first manifestations of acute subendocardial myocardial infarction patients with a history of 20 cases and clinical characteristics, according to ECG, dynamic changes of enzymes, Killip classification of cardiac function and cardiac color report indicators of cardiac function, acute acute subendocardial myocardial infarction with acute left heart failure occurred in the characteristics and causes.

综合分析20例以急性左心衰竭为首发表现的急性心内膜下心肌梗死20例病人的病史和临床特点，根据心电图、心肌酶的动态变化、 Killip 心功能分级和心脏彩超报告的心功能指标，探讨急性急性心内膜下心肌梗死发生急性左心衰竭的特征和原因。

Background and Methods:Coronary heart disease attack induced by obstructive sleep apnea syndrome is well-documented in retrospective study,but acute myocardial infarction and malignant arrhythmia triggered in acute stage,especially in superacute stage,are less-known.

报道 3 例阻塞性睡眠呼吸暂停综合征病人，例 1 表现 OSAS 诱发心绞痛逐渐演变为急性心肌梗死，例 2 在急性心肌梗死过程中引起高度窦房、房室阻滞和心脏停搏，例 3 在急性心肌梗死基础上每有呼吸暂停发作便激发出室速和室颤。

Result: The series of Muskone can improve myocardial ischemia and infarction in experimental canines, and relieve significantly the degree of myocardial ischemia determined by epicardial electrogram mapping,decrease the range of myocardial ischemia determined by epicardial electrogram mapping and decrease infarction zone determined by N-BT staining method. And it has a significant inhibition on activity of ET induced by myocardial ischemia and infarction, and increases 6-Keto-PGF1αand 6-Keto-PGF1α/TXB2 induced by myocardial ischemia.

结果：冠心苏合丸系列组方具有明显改善犬急性心肌缺血和心肌梗死的作用，明显减轻由心外膜电图标测的心肌缺血程度及范围；减小经N-BT染色所显示的梗死区；对心肌缺血及心肌梗死引起ET的活性有明显抑制作用，同时升高血浆6-Keto-PGF1α和6-Keto-PGF1α/TXB2的比值。
