The average weight of the other group of0fetus-es is less than00g when they were born.Among them,7babies were well developed,butwere hypogenetic,with abnormal blood flow,point out intrauterine growth retardation.

另0例胎儿出生时体重小于00g，其中7例新生儿虽体重较正常儿偏小，但发育正常；另例胎儿血流动力学指标异常，提示胎儿宫内窘迫，导致异常分娩，新生儿生存率低。

Results The average weight of the50normal ges-tated babies is more than2500g,and the babies were well developed.The average weight of the other group of50fetus-es is less than2500g when they were born.Among them,27babies were well developed,but23were hypogenetic,with abnormal blood flow,point out intrauterine growth retardation.

另50例胎儿出生时体重小于2500g，其中27例新生儿虽体重较正常儿偏小，但发育正常；另23例胎儿血流动力学指标异常，提示胎儿宫内窘迫，导致异常分娩，新生儿生存率低。

Objective To evaluate effect of maternal hypothermic cardiopulmonary bypass on fetal hemodynamics.

目的 探讨孕羊低温体外循环对胎羊血流动力学的影响。

The substantial alteration by 160% in the range of the blood flow pulsation can negatively affect the function and plasticity of the blood circulatory system and may potentially lead to the development of hypertonic or hypotonic symptoms in the human body.

在血流脉动范围内，透过160%相当可观的变化，可能对血循环系统的功能及塑性具负作用影响，并且可能潜藏在人类身体导致张力亢进或低压症状的发展。

Methods 21 LEPP patients with clinical highly suspected acute pulmonary embolism underwent (superscript 99m)Tc-MAA veins imaging and pulmonary perfusion imaging. Vena caval filters were inserted and thrombolysis were given in patients with big area APE and/or iliofemoral vein thrombosis indicated by (superscript 99m)Tc-MAA imaging. Thrombolysis was given in patients with small area APE and/or subpopliteal vein thrombosis.

对21例LEPP临床高度疑为急性肺栓塞患者行，(上标 99m)Tc-MAA下肢深静脉显像、肺血流灌注显像，(上标 99m)Tc-MAA显像提示大面积APE和／或髂股深静脉血检患者行下腔静脉滤网放置+溶栓治疗，小面积APE和／或腘静脉以下DVT单纯溶栓治疗，治疗2~4周后复查PPI。

The changes on vessal"s structure and function with EH is called vascularremodeling, including:①vas wall incrassation, especially on middle-level,lead the proportion between wall and cavity increased, the resistance of bloodstream and the reaction to the shrink substance is tone up;②resistance vasis decreased, especially on dia 12-25μm"s vas, and bring a series of functionabnormity with it.

与高血压伴随的血管结构和功能的变化，即是血管重构(Vascular Remodeling，VR)主要包括：①血管壁增厚，尤其是中层肥厚，导致壁与腔之间的比例明显加大，血流阻力和血管对缩血管物质的反应性增强；②阻力血管变得稀少，尤其是直径12-25μm的阻力血管数目明显减少，随之产生一系列血管功能异常。

Routine CT and MR examinations can only detect infracortical cerebral arteriosclerosis, whereas CT perfusion mapping images can detect evident slowed down cerebral focal blood flow Pictures 3, 4, 7, 8

常规CT和MR检查仅可见皮层下动脉硬化性脑病，CT灌注图像可见明显的脑局部血流缓慢（图3，4，7，8）。

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。
