METHODS Left ventricular ejective fraction, regurgitant velocity and regurgitant direction were examined by color Doppler echocardiography in 151 patients with medium mitral regurgitation. The results of LVEF, regurgitant velocity and regurgitanting gradient were compared between patients with and without murmur grope.

随机选择151例经超声心动图检查，显示有中度及中度以上二尖瓣返流的患者，根据彩色多普勒血流显像分别测定LVEF、返流速度等超声参数，比较其在杂音组及无杂音组间统计学差异，分析其对听诊的可能影响。

Methods: With the help of CF type peripartal detective and diagnostic instrument, ventricular ejective resistance,arterial specificity resistance,arterial terminal resistance and total peripheral resistance were observed to investigate the changes of peripheral resistance;capillary flow velocity and circulatory continuity ratio were monitored to study the changes of microcirculatio...

运用CF型围产监测仪检测左室射血阻抗、动脉特性阻抗、动脉终端阻抗及总外周阻抗，以研究外周阻力变化；检测毛细血管血流速度及微循环灌注连续性比率，探讨微循环改变；同时探讨血容量与血粘度变化。

METHODS: After instrumentation with arterial and sagittal-sinus cannulae, electrocorticogram, and sagittal sinus Doppler flow measurement seven adult sheep were given a random sequence of short anesthetic infusions with methohexital, ketamine, and propofol.

斦otilde；法：7只羾，先在每只羾身举安置徨脉和失羶窦导管，脑皮层电图和失羶窦超声血流分析仪，然后随机给予小剂量的异丙酚，美索比托和氯胺酮进行短时间麻醉，同时采取多个血样标本和脑电图变化来评估药效。

The effects of IR and IP on hemodynamics, epicardial electrography, myocardial infarct size, cardiomyocytic apoptosis and gene proteins involving apoptosis (Fas, Bcl-2 and Bax) are observed in aneasthetized rabbit myocardium.

在麻醉家兔心肌IR模型上，观察IR和IP对血流动力学、心外膜电图、心肌梗死范围、心肌细胞凋亡和凋亡相关调控基因蛋白(Fas、Bcl-2、Bax等)的影响。

The effects of myocardial ischemia-reperfusion and RIP on hemodynamics, epicardial electrography, myocardial infarct size, cardiomyocytic apoptosis and gene proteins involving apoptosis (Fas, Bcl-2 and Bax) are observed in aneasthetized rabbit myocardium.

在麻醉家兔心肌IR(myocardial ischemia-reperfusion，MIR)模型上，观察MIR和肾脏IP(renal ischemic preconditioning，RIP)对血流动力学、心外膜电图、心肌梗死范围、心肌细胞凋亡和凋亡相关调控基因蛋白(Fas、Bcl-2、Bax等)的影响。

Department of Physiology, Institute of Basic Medicine,Hebei Medical University, Shijiazhuang 050017Abstract: The effects of ischemia-reperfusion and ischemic preconditioning on hemodynamics, epicardial electrography, myocardial infarct size, cardiomyocytic apoptosis and gene proteins involving apoptosis (Fas, Bcl-2 and Bax) were observed in aneasthetized rabbit myocardium.

在麻醉家兔心肌缺血-再灌注(ischemia-reperfusion，IR)模型上，观察IR和缺血预处理(ischemic pre～con～ditioning， IP)对血流动力学、心外膜电图、心肌梗塞范围、心肌细胞凋亡和凋亡相关调控基因蛋白(Fas、 Bcl-2、 Bax等)的影响。

Patients undergoing pulmonary embolectomy often experience hemodynamic deterioration during induction of general anesthesia.

患者行肺栓子切除术，在全麻诱导时，常面临血流动力学恶化。

On the basis of our experience from this study and the unpredictable nature of hemodynamic deterioration, we suggest that patients undergoing pulmonary embolectomy should be prepared and draped before GA induction, and a cardiac surgical team should immediately be available for emergent institution of cardiopulmonary bypass.

以我们这项研究经验为基础结合血流动力学恶化的不可预测性，我们建议行肺栓子切除术的患者在全麻诱导前应该准备并且消毒铺巾，心脏外科医生根据需要应立即可到，进行心肺转流术。

In conclusion, hemodynamic deterioration after GA induction develops frequently during emergent pulmonary embolectomy.

结论为，紧急肺栓子切除术全麻诱导后，血流动力学恶化经常发生。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
