OBJECTIVE:To determine umbilicus blood levels of interleukin-6(IL- 6),tumor necrosis factor-alpha and nitric oxide in neonatal HIE and elicit their roles in pathogenesis,so as to provide theoretical basis for improving HIE prognosis.

目的：旨在研究 HIE患儿脐血白细胞介素- 6( IL-6)、肿瘤坏死因子-α与一氧化氮的变化，并探讨其在 HIE发病机制中的作用，为进一步改善 HIE的预后提供理论依据。设计：以诊断为依据的病例对照研究。

In recent years,the impact of vasoactive substances on liver disease has become a hot spot,especially endothelinand nitric oxide.

近年来，血管活性物质对肝脏疾病影响的研究已成为一个热点，特别是内皮素和一氧化氮。

Remember, vasoconstriction means decreased blood flow and NO increases blood flow.

记住， 血管紧缩就是血流量减少，而一氧化氮能增加血流量

BACKGROUND: The structural and functional impairment of endothelium cells were mainly presented by lowered endothelium activity, reduced nitrogen monoxide production, as well as increased endothelium vasoconstrictor peptide.

背景：内皮细胞发生结构损伤和功能障碍的主要特征为内皮细胞活性降低或释放的一氧化氮减少，内皮缩血管肽产生增加。

Nitric oxide is involved in vasodilatation, and low levels are associated with mental and physical fatigue and sexual dysfunction.

Background— It has been proposed that under hypoxic conditions, nitrite may release nitric oxide, which causes potent vasodilation.

背景——过去已经提出，在缺氧条件下，亚硝酸盐会释放引起有效血管舒张的一氧化氮。

Nitric oxide is an important regulator of some liver functions, such as enhancement of vasodilation, control of immune and inflammatory reactions, and affection of cell proliferation.

一氧化氮是重要的调控因子影响肝脏功能甚钜，例如：血管扩张、免疫与炎症反应的控制以及细胞增生。

Aortas were harvested for assessment of vasomotor function by isometric force recordings.

血管内皮一氧化氮合成脢及p47phox 的蛋白质表现则用西方墨点法记录。

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。
