The opening of leptomeningeal anastomoses vessel is the important way of collateral circulation in cases of serious stenosis or occlusion of MCA,the collateral flow between MCA and ACA is dominant. The RVACA/RVPCA can reflect the hemodynamic changes、the state of leptomeningeal anastomoses vessel when the MCA was serious stenosis or occlusion; There was a inverse correlation negative correlation between the RVACA/RVPCA and the NIHSS.

⑴在MCA中度以上狭窄或闭塞的情况下，皮质软脑膜吻合血管开放成为侧支循环的主要途径，以MCA-ACA之间的代偿为主；⑵RVACA和RVPCA在一定程度上可以反映MCA狭窄或闭塞时颅内血流动力学的改变、软脑膜侧支吻合的功能状况及有效程度；⑶RVACA和RVPCA与患者的NIHSS评分呈负相关，RVACA和RVPCA值越高的患者，其神经功能缺损程度越轻。

To observe the effects of SGDP given through sublingual tablets on hemodynamics and myocardial oxygen consumption in anesthetic dogs which were operated to expose heart, we put the electro-magnetic flowmetre feeler onto the the levo of coronary artery and the root of aorta to measure the the coronary arterial blood flow and cardiac output, left ventricular pressure was observed by the pipe into the left ventricle of the heart.

为观察舒冠滴丸舌下给药对麻醉犬心脏血流动力学及心肌耗氧量的影响，实验采用开胸暴露心脏，于冠状动脉左旋支及主动脉根部放置电磁流量计探头，分别测冠脉血流量和心输出量。左心室插管测左室内压。

Were proposed. It is a new lifeful direction for the hemodynamics study to well utilize the advantages of modern information technology, and form an integrated, advanced inter-discipline research and development field.

充分发挥现代信息技术的优势、形成集成化的、多学科综合交叉的先进研发领域，是血流动力学的研究充满活力的新方向。

METHODS: Fortyfive aged healthy crossbred dogs (15±7) kg were divided into 3 groups: tetramethlpyrazine group, verapamil group and control group. The operation was performed to ligate the near part of the LAD through left minimal thoracic incision to block 75% of the blood flow respectively.

将45只犬分为川芎嗪，维拉帕米和对照组3组，结扎LAD阻断血流75%，分别测定3组结扎前及结扎后不同时段的分泌型P选择素、内皮素1（ET1）、一氧化氮及心肌肌钙蛋白T的含量变化，Western blotting法检测心肌组织Pselecntin基因表达情况。

The operation was performed to ligate the near part of the LAD through left minimal thoracic incision to block 75% of the blood flow respectively. The expression changes of endothelium derived factors NO, ET1, sPselectin and CTnT before ligation and at different time points after ligation were detected and Pselectin gene of cardiac muscle was determined by Western blotting.

The fetal growth index and the umbilical artery blood flow were detected by colored Doppler ultrasound before treatment, one week after treatment and before termination of pregnancy. Meanwhile the lipometabolic index and coagulation function index were monitored and the prognosis of newborns was closely followed up.

治疗前、治疗后1周及终止妊娠前，行彩色超声检查，监测胎儿生长情况和脐血流变化，同时监测各项脂代谢指标和凝血指标，记录新生儿情况并进行随访。

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。
