The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

应用二维超声心动图在胸骨旁左心室长轴观测量左心室舒张末期内径、室间隔和左心室后壁舒张末期厚度，采用Teichholtz公式计算左心室射血分数，采用Devereux校正公式计算左心室心肌质量，左心室心肌质量指数=左心室心肌质量/体表面积；在心尖四腔心和心尖两腔心切面，应用组织多普勒成像获取室间隔、左心室侧壁、前壁和下壁的基底段和中间段8个心肌节段沿左心室长轴运动的速度频谱，测算左心室局部心肌松弛不同步性指数(regional left ventricular relaxation asynchrony index， AI)；在心尖四腔心切面，应用彩色M型多普勒超声心动图测量左心室舒张早期血流传播速度。

PQDS maybe prevent and treat ventricular remodeling with improving systolic and diastolic function of cor sinistrum in ventricular remodeling rats.

ConclusionG-Rb has protective effects on ventricular remodeling through improving systolic and diastolic function of cor sinistrum in ventricular remodeling rats,increasing anti-oxidase activity, reducing the damage of free radicals and vasoactive substance in myocardium and correcting disequilibrium of PGI2/TXA2 in ventricular remodeling etc.

结论G-Rb对大鼠心室重构具有保护作用，可能与其改善心室重构大鼠的左心收缩和舒张功能，增强抗氧化酶活性，减少自由基及缩血管活性物质对心肌的损伤，纠正PGI2/TXA2失衡等机制有关。

Shone's syndrome is a rare congenital cardiac condition thatconsists of up to four obstructive left-sided cardiac lesions.

Results:There was no blood rheologic change after MICABG under left heart bypass.

结果：左心辅助循环下MICABG术后血细胞技术流变学指标与术前相比无显著性变化。

The changes of rales, respiration rate, heart rate, arterial blood gas, cardiac function before and after NIV application were compared.

目的加强对早期应用无创机械通气治疗老年急性左心衰并呼吸衰竭的认识。

Emergence of left heart failure is high blood pressure indicates that the late stage of heart disease, when patients have obvious symptoms.

出现左心衰竭则预示着高血压性心脏病的晚期阶段，此时患者有明显的自觉症状。

Methods After heart failure model was induced successfully in 10 sheep, PUCA pump was inserted through aorta and the aortic valve orifice with its tip located in the left ventricle. It was then activated to support the hemodynamics for 3 hours. Hemodynamic parameters were monitored and recorded before thoracotomy, heart failure, and every 60 min after the support. Platelet and plasma free hemoglobin were tested during the experiment.

方法对10只绵羊诱导左心衰竭模型建立成功后行PUCA泵辅助3h，监测并记录血流动力学参数，采动脉血人工计数血小板并测定血浆游离血红蛋白；经辅助3h后检查肾、隔膜泵及导管血栓形成的情况。

Each year the lives of millions patients are saved with artificial heart valves and liver as well as artificial kidney and left heart assistant device. And innumerable artificial organs are used to rehabilitate people's organ defect.

从人工心脏瓣膜到人工肝肾和左心辅助装置等，每年可挽救数百万危重患者的生命；而每年用于修复人体缺陷的人工器官更是不可胜数。
