心收缩

Combination of natrium of conclusion saltpetre general is much cling to the heart failure after amine treats MI, can drop heart around negative charge already, increase power of cardiac muscle systole again, increase cardiac output, curative effect is very satisfactory.

结论硝普钠联合多巴胺治疗MI后心力衰竭，既能降低心脏前后负荷，又增加心肌收缩力，增加心输出量，疗效非常满足。

In the campaign, the increase in cardiac output, systolic blood pressure will also increase.

而在运动时，心输出量增加，收缩压也会随之增加。

Methods: Randomly divided 80 cases with chronic cardia failure into two groups, regular therapy group and bisoprolol group with 40 cases per group. Regular anticardiac failure therapy, including cardiac and diuretic therapy, was employed to patients in regular therapy group; while the combined therapy of regular therapy and bisoprolol was employed to patients in bisoprolol group. Compared the heart rate, left ventricular diastolic dimension, left ventricular systole dimension, left ventricular ejection fraction before and after therapy and efficiency of both groups.

With the continuous infusion of remifentanil at the rate of 10μg·kg-1·h-1, group S was inhaled sevoflurane of 0.5～1MAC and group P was infused with propofol of 4～6 mg·kg-1·h-1 Hemodynamic parameters (HR、MAP、CO、SV、SVR、ACI、LCWI)were measured with Bioz.com CardioDynamics at different times before and after pneumoperitoneum. At the end of surgery, all the anesthetics were stopped and the awakening condition was observed.

在持续输注瑞芬太尼10μg·kg-1·h-1的基础上，S组复合吸入0.5～1MAC的七氟烷，P组复合输注4～6mg·kg-1·h-1的异丙酚，采用Bioz.com监测仪测定气腹前后各时点的血流动力学指标，包括心率、平均动脉压、心输出量、每搏输出量、外周血管阻力、心肌收缩指数、左室做功指数。

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.

得到如下结论：(1)相同的吸湿性，在30％PVF(颗粒体积分数：Particle volume fraction，PVF)前增加PVF，层间脱胶损伤值显著增加；此后损伤值的增加趋于平缓；(2)保持层间强度和PVF不变，层间脱胶损伤随吸湿率的增加而接近线性增加；(3)FCC(面心立方：Face-centred cubic，FCC)模型层间脱胶损伤的预测结果和实验数据基本吻合；同时此模型可以用于预测牙齿填充材料三点弯曲实验的临界载荷。4、建立理想牙齿修复结构，利用有限元方法研究了同时考虑聚合收缩和吸湿膨胀耦合作用下的填充修复材料和粘结界面层材料性能对牙齿修复结构的力学行为的影响，得到如下结论：(1)低弹性模量的牙齿填充修复材料能限制天然牙组织的位移，但天然牙组织的位移与粘结界面层的弹性模量无关。

It was suggested that contractility and pumping function of LV had a strong ability in reservation. 7. With increased HR, there was a decreasingly decrease in FTVI and TTVI and a significant compansatory increase in APFV、ATVI and AFF (HR＜100BPM) and in peak flow velocity (HR≥100BPM). 8. There was no differences between males and females in cardiac function.

提示心率增快造成心肌工作时间延长。6、随心率加快，心输出量及CI增加(P均＜0.001)，EF及ΔD％无变化，MVCF增强(P＜0.05及0.001)，提示左室收缩功能及泵功能有较强储备能力。7、随心率加快，ETVI及TTVI减小(P＜0.05～0.001)，其代偿方式为APFV加快，ATVI及AFF加大(P均＜0.001)，及心率快于100次/分，E、A峰融合后的峰值流速增加。8、男、女性心功能无差异。

Arterial elastance and entricular end-systolic elastance were similarly increased in hypertensive controls and HFnlEF patients compared with healthy controls.

而高血压对照组和射血分数正常的心衰患者组血管弹性回缩率和收缩末期心室弹性回缩率都有所增加。

Compared with pre-HDT, the indexes of cardiac systole function in bicycle ergometric group had no significant changes, SV and CO decreased (P.05) in the 1st day of HDT.

Methods An isovolumic Langendorff perfused rat heart model was used.After 30 minutes of equilibrating perfusion,the HSPT group(n=8) was preconditioned by 15 minutes of hyperthermic oxygenated cardioplegia at 42℃(Control,n=8,at 37℃),before 100 minutes of cold preservation,followed by 30 minutes of reperfusion.

Wistar大鼠16只，随机分为HSPT组（n=8）和对照组（n=8），建立Langendorff离体鼠心等容收缩模型；平衡灌流30分钟后，分别用42 ℃和37 ℃的含氧停搏液灌注15分钟，然后冷停搏100分钟，再灌30分钟。

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.
