Three-dimensional DPI can stereoscopically show the network of cancer blood vessels.

三维血流能量图可获较完整肝癌肿瘤血流立体血管网图像，且与选择性肝动脉血管造影的血管分布特征相似。

Results: 3D CT completely and stereoscopically demonstrated the lesion's morphology, as well as the relation to the adjacent vessels in all 37 cases. The inner and outer pleurae near the lesion and the relationship between SPN and adjacent bronchi were well displayed in 34 cases.

结果：3D CT完整显示了37例SPN立体形态和结节与周围血管的关系及血管类型，直观显示34例SPN相邻胸膜内外侧面形态改变和结节与周围支气管的关系，3D CT形态分型，在良恶性SPN上有差异。

HAase may degrade antiangiogenic HA of extracellular matrix, which may stim ulate proliferation of endothelial cells and enhance the curative effect of grow th factors to myocardial ischemia.

HAase可降解细胞外基质中具有抗血管新生作用的HA，促进内皮细胞的增殖，有可能提高促血管生长因子治疗心肌缺血的局部疗效。

These include physical characteristics, such as repulsive forces resulting from the electronegative charge of both platelet and endothelial cell membranes, and biochemical attributes, such as the synthesis and release of inhibitors of platelet activation. Platelets respond rapidly to alterations of endothelial cells and to exposure of subendothelial structures by attaching firmly to the site of the lesion.

正常情况下，循环中的血小板与血管壁内皮细胞层紧密接触但不发生黏附，是因为血管内皮细胞具有一定的活性功能，包括一些物理特性如血小板和内皮细胞膜均带有负电荷产生相互排斥作用以及生化作用如合成和释放血小板活化抑制剂。

Retinal neovascularizationincreasingly extended with the time of RRD,and developed into vitreousand subretinal space,no iris neovascularization was seen.

随着脱离时间的延长，新生血管范围逐渐扩大并长入玻璃体和视网膜下腔，未见虹膜新生血管。

The basic pathological changes are fibrinoid necrosis, infiltration and exudation in the subcutaneous, submucous, and subserous tissues near the blood vessels.

本病的基本病理变化是毛细血管及小动脉发生免疫性病变，引起血管壁有纤维素样坏死，皮下、粘膜下及浆膜下组织的血管周围浸润及血浆样渗出，并有炎症细胞浸润。

Digital substraction angiography was performed 1 and 4 weeks after operation to observe the vessel changes, and then all canines were sacrificed for histological examination.

术后1周和4周行数字减影血管造影观察血管情况；4周后处死动物，行溃疡周围组织学检查。

Basic on the special mechanism of action of Apo2L/TRAIL, the broad-spectrum antitumor activity and superordinary safety of recombinant human soluble Apo2L/TRAIL in preclinical researches, and the progression of the antitumor study on endogenous antiangiogenic factors, two studies were involved in this paper, including phase I clinical trial of rh-Apo2L and the study on expression of the fusion proteins of human Apo2L and endogenous antiangiogenic factors.

基于Apo2L／TRAIL独特的作用机制、重组人可溶性Apo2L／TRAIL临床前体现出的广谱的抗肿瘤作用和良好的安全性、以及内源性血管生成抑制因子抗肿瘤研究进展，本课题开展了下述两方面的研究：①国产重组人凋亡素2配体(rh-Apo2L)的Ⅰ期临床研究；②人Apo2L／TRAIL与人血管生成抑制因子融合表达的基础研究。

These findings suggest that NC (13-17) may play important roles in pain modulation at supraspinal level in mice and elicits these effects through a novel mechanism independent of the NC receptor and the traditional opioid receptors The bioactivity study of NC related peptide-NST showed that: NST could dose-dependently reverse the effects of NC in antagonizing EMs-induced analgesia; NST itself could increase the MAP and HVBR of rat, and the tension of rabbit isolated aorta muscle strips.

对孤啡肽相关肽—NST的生理活性研究发现，NST可以剂量依赖的拮抗NC对抗内吗啡肽-1和内吗啡肽-2的镇痛作用；NST对NC的降低大鼠平均动脉压作用无显著影响，但其本身可以升高大鼠的平均动脉压，后肢灌流压和离体血管条的张力，在心血管系统方面是一个新的生物活性肽。

Methods:By means of regional perfusion and dissection in51cadavers,sural nerve blood supply from peroneal artery had been analysed .

通过51例尸体腓血管对腓目的：研究腓肠动脉对腓肠神经的营养，为吻合腓血管的腓肠神经神经移植提供依据。

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。
