血液动力学的

Surface tear of the endomembrane and atherosclerotic plaque induced by balloon dilatation, mechanical expansion and carotid sinus draw-off can adjust compliance of the carotid wall, change sensitiveness of carotid artery receptor, cause instability of hemadynamics and defluxion of plaque fragments, lead to hypotension, bradycardia, hypertension and vascular embolism. How to control and reduce occurrence of above-mentioned complications is a main problem in present studies.

但由于球囊扩张、支架置入机械扩张和牵拉，颈动脉窦引起内膜和动脉粥样硬化斑块的表面撕裂，调整了颈动脉壁顺应性，改变了颈动脉受体的敏感性，引起血液动力学不稳定和斑块碎片脱落，引起低血压、心动过缓、高血压及血管栓塞等并发症，如何控制和减少上述并发症的发生是目前研究的主要问题。

As the body response for the trauma, the adipose tissues as blood serum behavior in the wounded tissue were suffered mobilization. At the same time, the ectogenesis fat tissue entranced blood circulation. As the result of hemodynamics alteration, there were blood platelet and erythrocyte and leucocytes and lipid granules collecting on the surface of these lipid droplets. The volumes of these lipid droplets were enlargement. These lipid droplets were changed to fat embolus by the promotion of coagulation and fibrin deposition intra-blood vessel.

现代医学理论认为，外伤后组织存留的血清状态的脂肪组织受到动员，同时，损伤部位的血管外源性脂肪进入血循环，而创伤引起的机体反应使血液动力学发生改变，血小板、红细胞、白细胞及血脂乳化不稳定所析出的脂质颗粒等，均可聚集于以上脂滴的表面，使之体积增大，加之组织凝血活化酶的释放，促使血管内凝血，纤维蛋白沉积的发生，从而形成脂肪栓子，导致脂肪栓塞。

This paper is about the hydrodynamics of blood in flow channel on the principle of hydrodynamics, and the hydrodynamics equations of Newton-fluid and Casson-fluid in rectangle channel. It also includes the studies of the diphasic flow. The fluid model selection is discussed from the examples in the hemorheology studies using flow channel technique.

本文用流体动力学原理，研究了流动渠道中的血流动力学问题，分别推导了牛顿流体、Casson流体在矩形渠道中的流体动力学方程，文中还对流动渠道内的二相流问题进行研究，并就血液流变学研究中利用流动渠道技术的应用实例，讨论了流体模型选择问题

One study, which evaluated the haemodynamic and neurohumoral responses in 12 patients following a single ,5 litre total paracentesis concluded that it was safe to omit the use of albumin in these patients.96 However, many experts in the field have reservations on basing such a recommendation on a single small unrandomised study.

有一个研究评估了12例患者单次＜5L的全腹腔穿刺放腹水后的血液动力学和神经激素反应，结论是在这些患者不应用白蛋白是安全的。96不过，该领域的许多专家对于将这样一个建议建立在一个小样本非随机化研究之上持保留意见。

Objective:To studying the hemodynamic characteristics of umbilical artery blood flow pulsatility in fetal sheep.

目的：经胎羊腹主动脉注射微球的方法阻塞胎盘，建立胎儿窘迫的动物模型，研究脐动脉搏动指数的血液动力学特点。

Although it is well established that these changes may originated from the altered transmural pressure and distribution of blood in different vessels, the mechanisms of this differential adaptation in vascular stru...

故我们推想：在模拟失重过程中，不同部位局部血液动力学变化也可能引起不同动脉VSMCs的钾、钙离子通道发生不同的适应性改变，并进而参与动脉收缩反应性的调节。

Lund concept-to decrease the intracranial volume by the way of promoting the re-absorption of interstitial fluid in blood capillary bed-has been systematically studied too. But the investigation about cerebral vein system-the biggest blood storeroom-was less reported to review relative literatures. We carried out the pilot experiments to describe brain bridging veins in porcine and underlaid deeper research about human brain bridging veins by initially approaching possible ICP regulation mechanism.

动脉血容量反映了脑组织的灌注，在一定范围内自动调节维持颅内压的平衡，在此调节机制中发挥作用的动脉血流动力学的改变也已被深入的研究和描述，通过促进毛细血管对组织间液的重吸收进而减少颅内容物体积的&Lund&概念也得到较深入的研究，而涉及颅内最大的血液贮存库-脑静脉系统的研究较少，文献报道也较少。

Though the primary stimulator of 1H is not clear, it is related to physical, cell and body fluid IH is a chronic process involving multiple faction injury and blood flowing abnormal are revamped as the main reason, the proliferation level depend on the length and width of the injure of vessel large amount research illustrate injury cause many growth factor infolded in IH, for example: template derived growth factor, fibroblast growth factor, transmission growth factor , endothelin (ET-1) et al, some early responsive gene such as c-fos、c-jun c-myc also take part in SMC proliferation after vessel injury.

虽然IH的确切起始刺激因子并未阐明，但已知与物理、细胞和体液因子有关。IH是一个多因素参与的慢性过程，损伤和血液动力学异常一真被认为是IH的主要因素。内膜增殖的程度有赖于血管损伤的长度和深度。近年来大量的实验研究结果表明，损伤等刺激引起的众多的生长因子样物质在IH中起关键作用。如血小板源性生长因子、碱性纤维母细胞生长因子、转化生长因子β、内皮素-1（ET-1）等诸如C-fos、C-jun、C-myc等早期应答基因也参与了血管损伤后SMC的增殖。

The lack of a well-characterized in vitro model of load-induced cardiac hypertrophy has hampered further mechanistic investigation in this area, and little is known as to how mechanical load in initially converted into intracellular signals of gene regulation.

以往对心肌肥厚的实验研究基本上采用体内实验方法，然而，在体的实验研究由于受血液动力学、激素、神经反射的影响，不能恰当地反映一些因子或激素在心肌肥厚中的意义。

Using an epidural catheter placed at the level of T1-2 or T2-3, seven patients scheduled for awake CABG received TEA for total arterial myocardial revascularization after partial lower sternotomy.Six patients remained awake and spontaneously breathing during the entire procedure, but one required intraoperative intubation for respiratory distress caused by phrenic nerve palsy. Hemodynamics were stable throughout surgery without significant arterial hypercarbia. All patients rated TEA as "good" or "excellent."

七个患者被安排在清醒的CABG接受TEA，在部分下肢手术后，使用安置於 T1-2 或 T2-3 的硬膜外导管，以进行总动脉的心肌血管更换术，其中六名患者保持清醒，并且在手术过程中自然地呼吸，但是一位患者因为隔膜神经瘫痪导致呼吸困难，而需要进行手术中的插管，血液动力学在手术过程中是稳定的，并未发生动脉的血中二氧化碳含量过高，所有患者认为TEA是&良好或极佳的&。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
