心脏收缩的

The present invention shrinks the tissue in the heart (10) by selectively heating infarcted scar in order to reduce the size of the surface of the infarcted scar, make the soft part of the scar tissue become rigid, reduce the wall tension of shrinking the ventricle, and increase the total pump efficiency of the infarcted heart (10) by removing ventricle aneurism.

本发明通过有选择地加热梗塞瘢痕，收缩心脏（10）中的组织以缩小瘢痕组织表面积（18）的大小、使瘢痕组织的松软部分变硬、减少心室收缩的壁张力，并通过消除心室动脉瘤来增加梗塞心脏（10）总泵送效率。

Even without complications, the increase with age, systolic blood pressure also increased, and cardiac contractility and conductivity will decrease.

即使无合并症的情况下，随着年龄的增长，收缩压也会升高，而心脏收缩性和传导性会下降。

Cardiac output by the diastolic venous return by blood to the heart and the effects of cardiac contractility.

心输出量受心脏舒张时由静脉回流到心脏的血液量和心脏收缩力的影响。

Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

For the purpose of studying the effects of decrease of cardiac contractility on orthostatic response, the time-varying elastance modulus E in the Suga and Sagawa heart model has been expressed by a product of a parameter standing for the cardiac contractility and a normalized function.

为研究心肌收缩性能降低对立位应激反应的影响，把Suga和Sagawa的心脏收缩模型中的时变弹性系数E用一个与心肌收缩性能有关的参量〓和一个形式简单、控制参量少的归一化函数〓的积表示。

Objective To observe and compare the effects of exercise on the cardiac function during 30 d head-down tilt bed rest, and to see if these protocols would positively affect cardiac function. Methods Fifteen healthy male volunteers were randomly divided into control group, lower limb muscular exercise group and bicycle ergometric exercise group, with 5 in each group.

目的 本实验利用头低位卧床模拟失重，通过观察和比较30 d卧床期间不同体育锻炼方式对心脏收缩泵血功能的影响，旨在进一步明确体育锻炼对失重后心脏功能变化的对抗效果，为制定我国载人航天时航天员失重对抗方案提供实验依据。

Effects of exercise on heart function during 30d head-down tilt bed rest We observed and compared effects of lower limb muscular exercise with bicycle ergometric exercise during 30 d HDT bed rest on the changes of heart systole function and heart pump function.

30 d头低位卧床期间体育锻炼对心脏功能的影响本实验通过观察和比较30 d -6°HDT卧床期间下肢肌力训练或自行车功量计训练对心脏收缩泵血功能的影响。

These results suggested that 30 d HDT bed rest has induced significant reduction in heart systole function and heart pump function. The limb muscular exercise and the bicycle ergometric exercise to some extent can improve the heart systole function; however, the bicycle ergometric exercise was better.

结果提示，30 d头低位卧床可引起心脏收缩泵血功能下降，下肢肌力训练和自行车功量计训练可在一定程度上改善心脏收缩功能，其中自行车功量计训练的对抗效果更佳。

At the one-cell stage, each embryo was injected with gradient doses of 2-8ng MO. The control morpholino, was purchased from Gene-Tools.To test the knockdown effectiveness of the morpholino, the tbx2-EGFP (enhanced green fluorescent protein) construct was generated. And coinjection of morpholino with mRNA tests its specificity of the morpholino. Overexpression of tbx2 via mRNA microinjection helps us understand gaining function of tbx2. Results The tbx2-EGFP construct tests the knockdown effectiveness of the morpholino. Zebrafish embryos lacking tbx2 function have defects in cardiac contractility, rhythm and morphology in a dose-dependent manner. The embryos with c-MO are normal in development. Coinjection of morpholino with mRNA rescue the phenotype of tbx2 knocking down. The phenotypes include pericardial edema, hypogenetic ventricle, dilation of atria, arrhythmia, bradycardia, asystole, abnormal atrioventricular canal, aberrant valve and blood regurgitation.

结果荧光蛋白融合标记实验验证了tbx2-MO可以很好得阻抑斑马鱼胚胎tbx2的表达，tbx2-MO组胚胎在心脏收缩性、节律和形态学发生上出现了异常，心脏畸形随着注射剂量的增加而出现比较一致的表型，而c-MO组胚胎没有出现明显的畸形；tbx2-mRNA和tbx2-MO的共注射减少了tbx2-MO胚胎心脏畸形的发生率及减轻了心脏畸形的程度，验证了所设计合成的tbx2-MO对tbx2基因的抑制作用具有特异性；tbx2-MO组胚胎心脏缺陷包括心室发育不良、心房扩张、房室管和瓣膜异常以及心率缓慢、心律不齐、心脏停搏、血液返流等，并根据心脏发育异常的程度分为轻、中、重度畸形组tbx2-mRNA基因过表达胚胎没有见到心腔的形成。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
