.to record the bp and hr15,30,45,60min in both groups.bp,hr were higher during anesthesia than before anesthesia significantly in control group;bp,hr were lower during anesthesia than before anesthesia significantly in observation group.discussion remifentail take from the bp,hr effectively during operation,reduce the blooding,ensure the operative field clean and maintain the hemodynamics tranquilization,so as to the operation go with a swing.

。观察记录手术前及手术开始后5，15，30，45min时患者收缩压及心率。与麻醉前比较，对照组患者麻醉期间收缩压及心率均明显升高，而观察组患者均显著下降，两者间差异有统计学意义。［结论］瑞芬太尼可有效地降低手术期间患者的血压及心率，减少手术视野出血，保持血液动力学指标稳定。

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 hemodynamic changes after peritoneal insufflation of CO2 were measured with Swan-Ganz catheterization,and the plasma concentration of epinepherine and nonepinepherine were measured before and after CO2 being insufflated into peritoneal cavity with high performance liquid chromatography-electrochemical method.

20例行腹腔镜胆囊切除患者，随机分成全麻组(A组，11例)和硬膜外＋全麻组(B组，9例)，采用Swan-Ganz导管技术，监测气腹时血液动力学变化，用高效液相色谱——电化学检测气腹前后血浆肾上腺素和去甲肾上腺素浓度。

In reconstructed LV during SR/RVP,multiple scars with one or more isthmuses were presented on the reconstruction of the LV.RF current was delivered during hemodynamically unstable VT in 4 pts and abolished all VTs,in other 8 pts RF current was delivered only SR/RVP pacing due to very unstable hemodynamic status or mechanic in jury.

在SR/RVP时标测，可见1个或多个疤痕区域，4例在诱发VT时放电，均终止了VT；另8例因极不稳定的血液动力学或机械损伤，在SR/RVP时行放电消融。

LPS, TNF-α and NO were overproduced in patients with liver cirrhosis. NO might play an important role in hemodynamic dysfunction.

肝硬化患者血浆LPS，TNF-α和NO生成增多，NO在门脉高压形成及血液动力学紊乱中起重要作用。

In all,10 patients were cured after mean follow-up 15.3±12.8 months.The causes of RFCA failure were demonstrated in surgical operation.In 3 patients without structural heart disease,ablation catheters were not located in distinct target sites during ablation of 2 left posteroseptal pathways and 1 right posterior wall pathway.In 2 cases of Ebstein?s anomaly,ablations were failed by serious tricuspid regurgitation and AP at epicardium.In one case with rhumatic valvular disease,ablation catheter did not achieve mitral annulus because of pathologic changes.Other 4 cases with congenital heart disease were associated with anotomical anomaly and serious hemodynamic disturbance.

s畸形合并房间隔缺损，1例为重度三尖瓣返流使消融电极不能稳定贴靠靶点，另1例为AP靠近心外膜面而致RFCA失败；1例风湿性心脏病联合瓣膜病因瓣膜及瓣下结构病理改变致RFCA失败；1例重度二尖瓣返流RFCA失败与病人不能耐受RFCA与AP定位于24区消融导管难以抵达有关；先天性心脏病大房间隔缺损、重度主动脉关闭不全及矫正性大动脉转位右旋心伴三尖瓣返流各1例，RFCA失败与解剖畸形、心内大分流等血液动力学障碍有关。

The hemodynamic mechanism has been considered to be the main factor related to the cerebral aneurismal growth and rupture.

尽管目前对脑动脉瘤发生发展的机制尚未完全阐明，但血液动力学机制被认为是导致动脉瘤生长乃至破裂的主要因素[1]。

objective to simulate the patient-specific aneurismal model with computational fluid dynamic software and analyze the characteristic of hemodynamics.

目的 应用计算流体力学软件结合有限元法对颅内动脉瘤进行三维数值模拟，分析动脉瘤的血液动力学特性。

Numerical simulation has become an important method for the study of cerebral aneurismal hemodynamics,which lead to a deep insight into the field of hemodynamic mechanism.

有很多的方法和技术被应用到脑动脉瘤血液动力学的研究中，包括临床影像学观察、动物实验及体外模型实验。

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。
