心肌梗死

The results indicated that MCA could improve the left ventricular systolic function in patients with conge stive heart failure and the mechanism possibly included the effects of increased the concentration of intracellular cAMP and protective on cardiomyocytes anoxi a injury.

结果显示，心先安能改善心力衰竭心肌梗死患者的左室收缩功能，其机制可能与升高很痒细胞内cAMP浓度、保护缺氧受损的心肌很痒细胞有关。

Dephosphorylated PLB inhibits SERCA_(2a) activity, whereas phosphorylated PLB dissociates from SERCA_(2a) and leads to enhanced contractibility.

反义PLB转染心肌细胞能有效抑制细胞内PLB的表达，增强SERCA活性，因而改善心肌梗死大鼠的心脏收缩功能。

the positive expression of pcna in the myocardium after myocardial infarction is a sort of repairing response to the injury. the injured cardiomyocytes with pcna positive expression have decreased contractile function.

心肌梗死后部分心肌细胞表达pcna是对缺血损伤的反应，pcna阳性表达的心肌细胞其收缩功能降低。

METHODS: The model of acute myocardial ischemia of rats was created by ligaturing the left coronary artery and followed with recording changes of EGG, the range of myocardial infarct and the levels of the AST, CK, LDH, SOD and MDA enzymes in blood serum to study the effects of gleditsioside on myocardial ischemia in rats.

采用结扎大鼠左冠状动脉的方法，造成急性心肌缺血模型，通过对大鼠标准Ⅱ导联心电图，心肌梗死面积及血清中天冬氨酸转氨酶、肌酸激酶、乳酸脱氢酶、超氧化物歧化酶和丙二醛的测定，探讨皂荚皂苷对大鼠心肌缺血的影响。

Methods: The model of acute myocardial ischemia in rats was developed by ligaturing the left descending anterior coronary artery. Forty male Wister rats were divided into normal control group, ischemia model group, Xuesetong group and Verapamil group. The effect of Xuesetong on the CPK, LDH, SOD and MDA in serum and myocardium and myocardial infarct range was observed.

采用结扎大鼠冠状动脉左前降支复制出大鼠心肌缺血再灌注损伤模型。40只Wister大鼠分为正常对照组、模型组、血塞通组及维拉帕米组，观察血塞通对大鼠血清磷酸肌酸激酶、乳酸脱氢酶、血清及心肌组织超氧化物歧化酶和脂质过氧化物丙二醛及对心肌梗死范围的影响。

aim: to reveal the significance of positive expression of proliferating cell nuclear antigen in myocardia of rabbits with myocardial infarction and the relationship between pcna positive expression and left ventricular function.

目的：阐明兔实验性心肌梗死模型中心肌增殖细胞核抗原（proliferating cell nuclear antigen， pcna）阳性表达的意义及其与心功能和心肌缺血的关系。

Objective To evaluate the diagnostic value of"cTnⅠ+H-FABP" in acute myocardial infarction, and the effect of heart- type fatty acid-binding protein on elevating the sensitivity of the composite diagnostic scheme.

目的 探讨心肌型脂肪酸结合蛋白与肌钙蛋白Ⅰ联合检测对于急性心肌梗死诊断的价值及H- FABP在增加心肌标志物组合诊断效能方面的作用。

All experiment animals lived well with no death or malignant arrhythmia following cell transplantation. Frozen sections of the heart showed a few blue-stained cells under the fluoroscope in the cell transplantation group 4 weeks later. This indicated that stem cells were successfully homing. Using hematoxylin-eosin staining, homing cells were distributed over the infarct zone, with the presence of single or mass. In the model control group, no blue-stained cells were determined.

细胞移植后两组大鼠均存活良好，未出现死亡及恶性心律失常，4周后细胞移植组心脏冰冻切片荧光镜检显示心肌内有少量胞核蓝染的细胞，提示干细胞成功归巢，结合苏木精-伊红染色，归巢细胞位于心肌梗死灶周边区域，呈单个或小团聚集；而模型对照组心肌切片未见胞核蓝染的细胞。

We intend to detect the expression of apoptosis related proteins Bcl-2, Bax and myoglobin in the autopsied hearts of sudden coronary death and acute myocardium infarction in order to find some sensitive, reliable markers for the forensic diagnosis of SCD and early AMI.

本实验拟用免疫组化的方法检测凋亡相关蛋Bcl-2、Bax及心肌结构蛋白肌红蛋白(myoglobin，Mb)在早期心肌缺血性损伤中的表达情况，从而为SCD和早期急性心肌梗死(acute myocardium infarction，AMI)的诊断提供灵敏、可靠的辅助诊断指标。

Today all kind of methods to treat MI such as drug, interventional and surgical therapy only can better myocardium ischemia but cannot rescue necrotized myocardium.

目前各种治疗心肌梗死的方法如药物、介入、手术治疗也只能改善心肌缺血，不能挽救坏死心肌。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
