OBJECTIVE To find a safe shunt of cardiac output of pumpless extracorporeal lung assist in the canine model with acute respiratory distress syndrome.

目的 探讨无泵型体外肺辅助技术对犬急性呼吸窘迫综合征模型血流动力学的影响，寻找安全的分流范围。

There is no overt disturbance on the hemodynamics in 25% shunt of cardiac output of pumpless extracorporeal lung assistance in the canine model with ARDS.

pECLA使用25％的分流量不会对血流动力学产生严重影响。

Copper pyruvaldehyde bis（N -methylthiosemicarbazone） complex, or Cu-PTSM, belonging to a class of neutral, lipophilic complexes ,is a positron emission tomography radiopharmaceutical that can be used to evaluate blood flow in the heart, brain, and tumors without following any side effect .

Cu-PTSM是中性亲脂性复合物，用于PET显像的放射性药物由于该制剂很容易扩散到细胞内，因此注射Cu-PTSM后可以了解心、脑和肿瘤部位的血流灌注状况，它不伴有副反应的发生，且合成比较容易，所以是一种非常有途的新型PET显像剂。

作者单位：610041 四川成都，四川大学华西医院核医学科 cu-ptsm是一种中性亲脂性复合物，用于pet显像的放射性药物。由于该制剂很容易扩散到细胞内，因此注射cu-ptsm后可以了解心、脑和肿瘤部位的血流灌注状况，它不伴有副反应的发生，且合成比较容易，所以是一种非常有前途的新型pet显像剂。

Racemic ketamine passes the placentalbarrier and has oxytocin-like properties but does not seem toaffect uterine blood flow.

消旋氯胺酮可以通过胎盘屏障并有催产素作用，但是看来对子宫的血流没什麼影响。

As its function of water reabsorption, concentration and dilution, the kidney shows its significant character as water-transportation.

由于肾脏具有对水的重吸收、浓缩及稀释等功能，所以水的转运就成为肾脏的突出表现，同时肾脏血流灌注量也非常之大。

Methods:Forty ASA Ⅰ~Ⅱ patients scheduled for selective laparoscopicassisted rectectomy were randomly divided into two groups:group A and group B.Group A received combined general and epidural anesthesia and group B received general anesthesia only.Hemodynamics changes,PaO2 HCO-3 and anesthetic doses were observed preoperation,perioperation and postoperation.

40例ASAⅠ~Ⅱ级择期行腹腔镜直肠癌根治术的病人，随机分为A组和B组各20例。A组为全麻复合硬膜外麻醉组，B组为单纯全麻组，分别观察两组病人手术期血流动力学变化、血气变化及全麻药用量。

Objective To compare the relationship between measurement of the time constantly derived from aortic regurgitant velocity spectra and catheter derived time constant, and to evaluate the effects of hemodynamic flow states and regurgitant volumes on the Tau AR.

目的 对比研究由主动脉返流频谱得到的时间常数Tau和心导管根据左室压力曲线得到的时间常数的相关性，评估血流动力学参数和返流容积对Tau－AR的影响。

虽然频谱多普勒对返流和分流性疾病的血流定量诊断具有一定价值，但有时检测比较繁琐，并且常常因湍流及联合瓣膜损害影响其准确性及广泛应用。

Although spectral Doppler echocardiography holds a certain of value in flow quantitation for regurgitant and shunt diseases, the detection method is complicated and tedious sometimes, and its accuracy and wide application are usually affected by the turbulence and the multi-valve impairment.

虽然频谱多普勒对返流和分流性疾病的血流定量诊断具有一定价值，但有时检测比较繁琐，并且常常因湍流及联合瓣膜损害影响其准确性及广泛应用。

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。
