More and more evidences have shown that traditional high 〓 cardioplegic solutions increase energy and oxygen demand during asystole; make more calcium entry into cells.

愈来愈多的研究表明：传统高〓心肌保护液于诱导心脏停搏期间增加心肌能耗、氧耗，介导〓内流并对传导系统抑制作用相对较弱，高〓所致的血管内皮细胞损伤也引起学者们的高度重视，如何减轻或避免高〓心肌保护液的不利影响，是心外科领域中一个亟待解决的难题。

Adult rats are divided into control group, intrapericardial injection group and negative group, sublingual vein injection group and negative group. 6ds after transfection, issues of heart, liver, lung and kidney are stained with X-gal to observe transfection to myocardium and non-target transfection. 3. CaN Aβ gene silencing in vivo. Adult rats are divided into Control group, hypertrophy model group, intrapericardial injection group and negative group, sublingual vein injection group and negative group.

二整体动物水平上探讨心肌有效转染途径：以PLacZ为报告基因，将成年大鼠分为空白对照纽(生理盐水心包腔内注射后超声导入)；转染质粒心包腔内注射组及其阴性对照组：质粒+微泡+酶的混合物心包腔内注射，超声导入；转染质粒舌下静脉注射组及其阴性对照组：质粒+微泡混合液经舌下静脉注射，超声导入。

Objective:To study the effect of spironolactone inhibiting proliferation on cultured myocardiac myofibroblasts and explore its possible mechanisms.

目的：研究螺内酯对培养的心肌成纤维细胞增殖的作用，揭示螺内酯抑制心肌纤维化的可能机制。

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。

The subendocardial and sub-epicardial tissues were separated from the mid-layer region with opthalmic scissors. Single cells in each region were obtained by gentle shaking and dispersing in a chamber filled with normal Tyrode's solution. The whole-cell patch clamp technique was used to record the current while change the composition of the perfusate.

采用胶原酶二步消化法分离兔心肌细胞，用锐利眼科剪分离左室游离壁内、中、外三层心肌，改变灌流液的成份，采用全细胞膜片钳记录离子电流。

One of them was identified as aldehyde dehydrogenase 2, and the others were both identified as mouse RIKEN cDNA 2900053E13, suggesting that the protein might be post translationally modified.

通过对差异蛋白的胶内酶解和高效液相色谱／离子阱质谱鉴定，发现其中一个蛋白点为乙醛脱氢酶2（aldehyde dehydrogenase 2），另外两个差异点鉴定结果为同一个蛋白RIKEN cDNA 2900053E13，提示该蛋白在正常和心肌缺血心肌的线粒体内修饰状态发生了变化。

Comparing with crystalloid and blood cardioplegic solution, self-blood cardioplegic solution is a good cardioprotection for infants in cardiopulmonary bypass and could provide satisfactory protection for the immature myocardium.

自体冷血停搏液对婴幼儿心内直视手术心肌保护优于冷血和晶体停搏液，对未成熟心肌具有良好的保护作用。

So if the old theory that we die with the heart cells we are born with is true, then people born before carbon 14 got into the food chain (nuclear testing didn't start until 1955) wouldn't have any carbon 14 in their heart cells.

如果根据心肌细胞不可再生理论，那么在C14进入食物链之前（1955年核试验开始前）出生的人心肌细胞内不会有C14，但事实并非如此，这些人的心肌细胞不仅含有C14，研究者还测定出了C14存在体内的时间。

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％。
