血流

Objective:To summarize the changes of hemodynamics in the perioperative period of laparoscopic choledocholithotomy Ttube drainage.

目的：探讨腹腔镜胆总管切开取石&T&管引流术(laparoscopic choledocholithotomy Ttube drainage，LCTD)患者围手术期血流动力学的变化。

LSCI has been applied in real-time investigation of photodynamic therapy induced vascular damage by use of the model of chick chorioallantoic membrane.

使用激光散斑衬比成像技术监测在不同光剂量、药剂量以及对照实验中的血流灌注和血管管径变化。

In the second group,the rabbits were treated only with the argon laser induced chorioretinal venous anastomosis. Results An anastomosis in experimental group was formed in 6 rabbits within 4-6 weeks after treatment while no anastomosis was formed in control group.

结果：通过眼底荧光血管造影检查和彩色眼底照像，实验组6只眼成功建立视网膜脉络膜吻合，检眼镜下激光击射部位静脉中断呈漏斗状陷入脉络膜；FFA显示远端及近端静脉内血流汇入吻合处，吻合形成时间为4~6周，对照组未形成吻合。

Creating chorioretinal venous anastomosis potentially offers a means of permanently bypassing the site of obstruction to venous outflow, to recovery the retinal blood circulation and to reduce the retinal ischemia. It is one of the methods curing the reason of CRVO and is demonstrated effective in non-ischemic CRVO patients using laser-induced chorioretinal venous anastomosis. Patients with ischemic CRVO have more severe situations and high risk factors of later neovascular complications occuring, the surgery of via a pars plana vitrctomy combined chorioretinal venous anastomosis can be the newest attempting treatment.

其发病机理和病因目前仍未完全阐明，也没有有效的治疗措施；除常规的药物和针对新生血管并发症的视网膜光凝治疗以外，近年来开展的各种旨在重建或恢复视网膜血液循环的激光和手术治疗方法正日益成为眼科界关注的焦点；利用建立脉络膜视网膜静脉吻合途径，使被淤滞的静脉血流经由脉络膜血管流出眼外，促进或者恢复视网膜血液循环，减少视网膜缺血缺氧状态的发生，是多途径CRVO对因治疗的方法之一。

Malfunction of choroidal blood flow is found in early stage of AMD.

在AMD的早期就可发现脉络膜血流的改变。

Conclusions— Hemodynamic and chronotropic responses to exercise are heritable and demonstrate suggestie linkage to select loci.

结论——对运动的血流动力学和变时性反应是可遗传的，并提示有与选择的基因座有可能的遗传连锁。

Well, in a recent study, scientists observed that when the participants felt rejected, the flow of blood increased to the area of their brain known as the anterior cingulated cortex.

嗯，在最近的研究中，科学家观测当试验参与者感到被拒绝的时候，血流会在脑部被称作大脑前扣带回皮层增加。

D: Well, in a recent study, scientists observed that when the participants felt rejected, the flow of blood increased to the area of their brain known as the anterior cingulated cortex.

是这样的，在最近的一项研究中，科学家们通过观察发现，当实验参与者感到被拒绝的时候，他们体内的血流会聚集到他们脑部一个被称为前扣带皮层的区域。

Well, in a recent study, scientists observed that when the participants felt rejected, the flow of blood increased to the area of their brain known as the anterior cingulated cortex.

：好吧，在近期的学习中，科学家们发现，当实验参与者在被拒绝时，血流会在脑部被称作大脑前扣带回皮层聚集。

Well, in a recent study, scientists observed that when the participants felt rejected, the flow of blood increased to the area of their brain known as the anterior cingulated cortex.

在最近的研究中，科学家们观察到当参与者感觉被拒绝，他的血流就会向大脑上涌。

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。
