(1) During the period of vasovagal syncope, both sympathetic and vagal nerve tones were inhibited.

（1）血管迷走性晕厥时，交感神经和迷走神经张力受抑制，导致血管扩张，血压下降。

Baekgroud: Spinal cord ischemia reperfusion injury is an serious secondary spinal cord injury. Trauma, arteriosclerosis, vasal abnormality, inflammation, vasal infarct, decompression after the diseases that can bring spinal cord compression, lessening the blood stream of the spinal cord temporarily ,because of clamping the aorta during the operation of aorta, all of which can engender different extent spinal cord ischemia.

背景：脊髓缺血再灌注损伤是严重的脊髓继发性损伤，创伤、动脉硬化、血管畸形、炎症、血管梗塞、各种产生脊髓压迫的疾病减压后以及在主动脉手术中，钳夹主动脉导致脊髓血液供应暂时性减少都可造成不同程度的脊髓缺血再灌注损伤。

Vasculogenesis and angiogenesis are two different process.

血管新生和血管生成是两个截然不同的过程。

Objective To experimentally study the expression of vascular endothelial growth factor after transarterial chemoembolization and its relationship with vasculogenesis and tumor cell proliferation.

目的 探讨大鼠移植性肝癌经动脉化疗栓塞后血管内皮生长因子的表达及其与血管生成和细胞增殖间的关系。

These findings demonstrate that angioblasts exist in the circulation during postnatla life and therefore,vasculogenesis might occur in adults.

实验结果证明人出生后阶段血循环中存在有成血管细胞，因此在成人中也可发生血管系形成过程。

It becomes evidently that endothelial progenitor cells are involved in postnatal reendothelization and vasculogenesis. It is suggested that endothelial progenitor cells will have clinical application prospects in vascular regeneration and treatment of heart and vascular diseases.

但近年的研究证实，内皮祖细胞参与出生后的内皮修复和血管新生过程，提示内皮祖细胞在血管再生和心血管疾病治疗中具有很好的应用前景。

Leptin exerts an angiogenic effect on HUVECs by stimulating proliferation, migration and the in vitro vasculogenesis ability.

瘦素通过促进HUVECs增殖、迁移和体外血管形成等作用促进血管新生。

Taken together, these results indicate that Hypb is required for embryonic vascular remodeling and provide a tool to study the function of H3K36 methylation in vasculogenesis/angiogenesis.

我们的这项研究结果证明HYPB基因在血管发育中具有重要作用，并为下一步研究H3K36三甲基化修饰在血管发育中的作用机制提供了一个良好的模型。

However, bone marrow derived endothelial progenitor cells have been isolated from peripheral circulation and shown to be incorporated into foci of physiological and pathological neovascularization, consistent with postnatal vasculogenesis in recent years.

然而 ，近年来发现循环中存在骨髓来源的血管内皮祖细胞，并与出生后血管发生密切相关，具有重要的生理、病理意义。

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。
