Internal echoes: 11 cases were homogeneous with high echoes, 4 cases were high echoes with low echoes, 1 cases was high echo with echoless, 1 cases was missed diagnosis. Blood signal were not found in all caseson on color pepoler US.

超声表现为均质型强回声11个，强回声区内分布低回声4个，囊实混合性回声1个，1个漏诊，彩色多普勒超声检查上述病灶内均未见明确血流信号。

METHODS: Rabbit models of autogenous vein graft were generated in both groups. After anaesthesia, a median incision was made at the neck to dissociate external jugular vein and common carotid artery of the left side. Following blood flow was blocked at the upper and down sides of the common carotid artery, blood vessels were transected to collect 4.0-5.0 cm external jugular vein at the left side, and placed among the common carotid artery at the same side after inversion. End-to-end anastomosis was performed using discontinuous ecstrophy.

两组兔均建立自体静脉移植模型，麻醉后颈前正中切口，游离出左侧颈外静脉及颈总动脉，在颈总动脉的上下两端阻断血流后，横断血管，取左侧的颈外静脉4.0~5.0cm，上下倒向后置于同侧颈总动脉之间，采用间断外翻法行端端吻合。

Methods Ultrasound was taken to detect the internal diameter of right brachial artery and ectatic rate under different conditions.And compared with normal contrast.

采用高分辨率超声诊断仪测量EH患者静息、血流后及含服硝酸甘油后的右肱动脉血管内径及扩张百分率，并与同龄正常对照组比较。

Use intermittent positive pressure ventilation mode in ALI dogs, calculate Elastance and Resistance, then change to PAV, set the assist ratio 80％、60％、40％、20％randomly, Observe the changes of respiratory mechanics、blood gas analysis and hemodynamics during mechanical ventilation.

对10条ALI犬先用间歇正压通气模式通气，同时弹性阻力和粘性阻力，然后将模式改为PAV，随机设置辅助比例80％、60％、40％、20％，观察通气期间呼吸力学、血气和血流动力学的变化。

Methods Random selective the light、midst and serious types of patients that the encephalic injury.

Objective To analyse the hemodynamic changes of children with endocardial fibroelastosis by two dimensional echocardiography.

目的 应用二维多普勒超声心动图技术对心内膜弹力纤维增生症患儿的血流动力学变化进行分析研究。

Objective To analyse the hemodynamic changes of children with endocardial fibroelastosis by two dimensional echocardiography.

摘 要：目的应用二维多普勒超声心动图技术对心内膜弹力纤维增生症患儿的血流动力学变化进行分析研究。

Conclusions— These findings suggest that increased hemodynamic load adersely affects endocardial function and is a potentially important contributor to thromboembolus formation in heart failure.

这些发现表明了血流动力负荷的增加对心内膜功能产生负面的影响，而且是一个在心力衰竭中导致血栓栓塞形成的重要潜在因素。

However, little is known about the degree of functional and hemodynamic improvement of severely ill heart failure patients who receive LV endocardial pacing vs.

然而，很少有人知道严重的心力衰竭病人接受左心室内膜和外膜起搏在心功能和血流动力学的改善方面有什麼差异。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
