Objective To investigate changes of vWF in vascular endothelial cells with acute hypoxia and assess its significance in the study of vascular injury and hypercoagulability.

目的 观察急性缺氧时内皮细胞中血管性血友病因子的变化及其与血液高凝状态之间的关系，确定其在反映血管内皮细胞损伤和血液高凝状态研究中的价值。

Objective To investigate changes of vWF in vascular endothelial cells with acute hypoxia and assess its significance in the study of vascular injury and hypercoagulability. Methods vWF in vascular endothelial cells and in blood were measured by immunohistochemical staining image analysis and ELISA technique.

目的 观察急性缺氧时内皮细胞中血管性血友病因子的变化及其与血液高凝状态之间的关系，确定其在反映血管内皮细胞损伤和血液高凝状态研究中的价值。

Herein, we report an unusual case with profuse watery sputum and multilobar consolidation on the chest radiography.

我们在这个报告中提出一个罕见的病例是以大量水状的支气管漏及胸部X光多肺叶实质病变来表现并快速进展成严重的缺氧性呼吸衰竭。

Thus, IDH1 appears to function as a tumor suppressor that, when mutationally inactivated, contributes to tumorigenesis in part through induction of the HIF-1 pathway.

因而异柠檬酸脱氢酶-1(IDH1)似乎是作为一种肿瘤抑制因子而存在，一旦通过突变使之灭活，则可能会部分的通过缺氧诱导因子亚单位α（HIF-1α）的途径而参与肿瘤的发生。

VEGF had direct neuroprotective effects on neurons, which may be mediated in vitro through VEGFR2/Flk-1 receptors,and decreased apoptosis on vitro neurocyte.

VEGF对神经元起直接的保护作用，并通过与VEGFR-2受体结合减少了缺血、缺氧下培养的体外神经元细胞的凋亡。

Vascular endothelial growth factor (VEGF or VEGF-A) is a hypoxia induced angiogenic growth factor that is potent in neurotrophy, neuroprotection, anti-apoptosis and cell proliferation.

VEGF是一种由缺氧诱导的血管生长相关肽，在脑内有比较丰富的表达。VEGF具有神经营养、神经保护、抗凋亡、细胞增殖、提高毛细血管渗透压等广泛的生物学作用。

Nikethamide still had the effect of stimulation of respiratory center and enhancement of ventilation even though chronic pulmonary obstruction with CO_2 retention was present.

但由于慢阻肺呼吸运动机械阻力增加、通气量的提高，将促使机体代谢率上升，可抵消兴奋呼吸所起的缓解缺氧和CO_2潴留的积极作用，甚至适得其反。

Chawla posits that the predeath spikes are most likely brief,"last hurrah" seizures originating in brain areas that were irritable from oxygen starvation.

Chawla认为死亡前的尖峰电压现象，非常像大脑因为缺氧而出现的&最后的欢呼&现象。

Hypoxia and carbon dioxide retention induce multiple organ failure contributed mostly to the changes of sero - enzyme in patients with chronic cor dis- ease.

结论缺氧和二氧化碳潴留引起的多脏器损伤是肺心病急性期血清酶变化的重要原因；伴发病是酶学变化的次要原因，但具有重要意义。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
