To measure the flow velocity of the lateral ascending cervical arteries and the small vessel into femoral epiphysis and RI of arteries.

测量髋关节外侧颈升动脉及股骨头骨骺终末血管的血流速度，动脉血管流速为收缩期峰值流速。

The authors consider that is abnormal coagulation in steroid-i nduced necrosis of femoral head,and it might be caused by exogen ous steroid damaged the vascular endotheliod of those intraosseous and extraosse ous;or the platelet and other coagulable active mass be actived by immunocomp lex deposited in the vascular wall.

认为激素性股骨头缺血坏死发病过程中，系统存在异常的凝血状态。这种异常的凝血状态很可能是外源性激素造成了骨内外血管内皮损害或免疫复合物沉积在血管壁，进一步激活了血小板及其它凝血活性物质后引起的。

In 19 hemangiomas, 9 focal hyperplastic nodules, and 9 other benign tumors, the typical enhancement patterns were slow enhancement and expurgation, swift enhancement and slow expurgation, and slow expurgation, respectively.

2良性病灶：19个肝血管瘤多为典型"慢进慢出"；9个局灶性增生结节多为快进慢出型，早期可见增强的中央血管及放射状血管，其余9个肝脏良性病灶多表现为"慢出"型。

In the operation,some important techniques,such as hypothermic injection,mode and position of anastomosis of the donor vessels with the recipient ones ha-ve been improved.Methods to establish and observe the extrasomatic blood circu-lation of the donor kidney were recommended in this paper.

对于手术至关重要的低温灌洗途径的选择、供体血管的解剖及与受体血管的吻合方式和部位等解剖学技术逐步进行了改进和完善，介绍了供肾体外血循环的建立和观察方法，提出了保护肾上极动脉的初步意见。

Shafie Fazel, cardiac surgery resident at TGH, University of Toronto surgeon/scientist program fellow and lead author of the study entitled,"Cardioprotective c-kit+ cells are from the bone marrow and regulate the myocardial balance of angiogenic cytokines," published today in The Journal of Clinical Investigation. When damaged heart tissue sends out an 'SOS' distress signal, this subset of bone marrow cells mobilizes quickly and stimulates the growth of new blood vessels in the heart.

一名来自多伦多大学的外科医生/科学家计划研究组的的成员，同时也是今天发表在《临床研究》中的"产生于骨髓的心脏保护细胞----C-kit+细胞调节着心肌血管生成因子的平衡"论文的主要作者----特里普勒总医院心外科住院医师这样描述，当心脏细胞受损时发出'SOS'的求救信号，这种骨髓细胞亚群快速动员和刺激新生心脏血管的生长。

Results The success rate of all flaps mentioned above were as high as about 96 percent.

结果 带血管蒂的或吻合血管的皮瓣、肌皮瓣移植术成功率均较高，约为96％左右。

A special form of angiography used by eye doctors is called fluorescein angiography.

一种特殊形式的血管造影用眼的医生，是所谓的荧光素血管造影术。

In clinical practice, it may reduce the need for fluorescein angiography because it seems to be especially useful in monitoring persistent retinal vascular leakage in patients who are clinically in remission.

在临床实践中，它可能会减少，需要荧光血管造影，因为它似乎是特别有用的监测持久性视网膜血管渗漏的病人谁是临床缓解。

Four dimensional CTA is a useful method to study the vasculature of the DIEAP flap.

四维CT血管显影是研究DIEAP皮瓣血管构造的理想方法。3。

The mechanism probably is that Pishang can inhibit the growth, movement and adheresion to extracellular matrix and endothelial cell of liver tumor cells, up-regulate the expression of nm23, down-regulate the expression of CD44, MMP-2, and inhibit the tumor neovascular by supressing the vascular endothelial cell, down-regulating the expression of VEGF, damaging the primitive mesenchymal cells and inhibiting neovascular gemmation.

砒霜具有明显的抗肝癌细胞作用，并有一定的抗侵袭与转移作用，其机制可能与其能抑制肝癌细胞增殖、迁移、阻止肝癌细胞与细胞外基质和内皮细胞粘附、上调肿瘤转移抑制基因nm23表达、下调肿瘤侵袭分子CD44、MMP-2表达以及通过抑制内皮细胞增殖、下调VEGF表达、损伤间充质细胞、阻止新生血管芽生等途径从而抑制肿瘤新生血管形成有关。

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。
