Methods 12 healthy male SD rats were anaesthetized and heparinised. The right carotid artery, jugular vein and two distal ileocolic veins were cannulated for blood transfusion, volume compensation, drug infusion, and blood sampling respectively.

方法健康雄性SD大鼠l2只，作右侧颈动脉、颈静脉插管；开腹后，经回结肠静脉作门静脉插管，分别用以输血、输液、给药、留样、检测等。

The kidney is composed of renal corpuscle , neck segment , proximal tubule, middle segment, distal tubule and collecting tubule.

To detect effects on apoptosis of cortex neuron in DHCA rats, the rat model of occluding bilateral common carotid artery in the deep hypothermic (21C) rats had been established, and flow cytometry, TUNEL, electron microscope, immunohistochemistry and RT-PCR had been studied.: part I: To establish a new rat model of cerebral ischemia/protect during DHCA: 20 SD rats were used in the experiment, little animal respirator was to assist anesthetized rat's respiration after tracheal cannula, artery press through artery spile in femoral artery, electrocardiograph, temperature, blood saturation of O2 (SaO2) and arterial blood gases were monitored during the whole experiment, blood flow of bilateral common carotid artery of rat were occluded about 60 minute when its temperature was reduced to 21 C by ice, then normal temperature was resumed.

本研究采用大鼠深低温颈总动脉阻断模型，应用流式细胞仪、电镜、原位缺口末端标记法、免疫组化法和RT-PCR技术分别检测深低温脑缺血对皮层神经细胞调亡的影响方法：第一部分深低温停循环脑保护大鼠模型的建立：SD大鼠20只，麻醉后气管插管辅助呼吸，用冰块将大鼠的体温降至(21±1)℃，阻断双侧颈总动脉，记录体温、心率、血压、血氧饱和度和血气分析，60分钟后恢复颈总动脉血流，用Longa等的5级评分标准评定4小时和24小时后大鼠神经系统损伤情况。

The slip knot was tightening by the drawn-string through the cardiac catheter which can be removed after decannulation. The modified Dennis cannulation was done with left ventricular assistance from the left atrium (via right external jugular vein) to the right subclevian artery in 6 dogs.

这种方法用于从右颈外静脉到左心房插引流管，和从右锁骨下动脉插灌注管行左心辅助的试验犬6例，在拔管后房间隔插管处可被闭合。

Results All 34 cases included 29 carotid atherosclerosis,10 mlid luminal stenosis, 12 moderate luminal stenosis, 5 severe luminal stenosis,2 segmental occlusion;15 calcified plaque,10 noncalcified plaque,9 mixed plaque ;The total CT value ranged from 20-1140Hu,and the CT value of calcified plaque ranged from 220-1140Hu,the CT value of noncalcified plaque ranged from 20-73Hu; hese 7 positive findings included 1 left common carotid artery abnomal origin,2 carotid artery aneurysm and 4 vertebral artery stenosis.

结果 34例患者中，颈动脉粥样硬化者29例，管腔轻度狭窄者10例，中度狭窄者12例，重度狭窄者5例，节段闭塞者2例；钙化斑块15例，非钙化斑块10例，混合斑块9例； CT值范围20-1140Hu，其中钙化斑块CT值220-1140Hu，非钙化斑块CT值20-73Hu；左侧颈总动脉起源异常者1例；颈动脉体瘤2例；椎动脉狭窄者4例。

Result The skewed parabolic profile is observed in CCA under 1:60 curvature and physiological average Reynolds number. As curvature and Reynolds number increase, the middle of horizontal profile appears sunken and the vertical profile is M-shaped. There are different profile shapes in different localities along the curved pipe.

结果 当颈总动脉的曲率等于1：60 时，在人生理平均流动雷诺数条件下，颈总动脉的速度剖面可用偏斜的抛物面来近似；当颈总动脉曲率增大或流动雷诺数增大时，弯曲平面上的速度剖面中部出现下凹趋势，垂直方向上出现M型速度剖面；沿管轴不同位置上的速度剖面形状不同。
