RESULTS: Extract of Sonchus oleraceus markedly prolonged the living time of the fasting, hypoxia experimetal mice, the formation time of carotid artery thrombosis, decreased blood viscosity shear rate (compared with control, P.01), prevent myocardial ischemia caused by hypophysin.

结果：苦苣提取物灌胃给药12.5g/kg和6.3g/kg均能明显增加小鼠常压下耐缺氧存活时间，能够延长饥饿小鼠的生存时间。3.2g/kg可明显降低大鼠血液黏度，延长大鼠体内血栓形成时间。

Objective To study the expression of hypoxia-inducible factor-1α in vulvar squeamous cell cancer.

目的 探讨HIF-1α与外阴鳞癌的关系。

The transition from the systemic inflammatory response syndrome to seere sepsis and septic shock inoles a myriad of pathogenic changes, including circulatory abnormalities that result in global tissue hypoxia.1,2 These pathogenic changes hae been the therapeutic target of preious outcome studies.12 Although this transition occurs oer time, both out of the hospital and in the hospital, in outcome studies interentions hae usually been initiated after admission to the intensie care unit.12 In studies of goal-directed hemodynamic optimization, in particular, there was no benefit in terms of outcome with respect to normal and supranormal hemodynamic end points, as well as those guided by mixed enous oxygen saturation.9,13 In contrast, een though we enrolled patients with lower central enous oxygen saturation and lower central enous pressure than those studied by Gattinoni et al.9 and with a higher lactate concentration than those studied by Hayes et al.,13 we found significant benefits with respect to outcome when goal-directed therapy was applied at an earlier stage of disease.

从全身炎症反应综合征转为严重脓毒症和脓毒性休克牵涉大量发病的变化，包括导致全身性缺氧的循环紊乱。这些发病的变化成为先前结果研究的治疗学目标。尽管这些转变随着时间的流失而逐渐出现，既可以在院外，也可在院内，在结果研究中，干预措施往往在进入ICU之后才启动。特别的，在那些目标导向血流动力学最优化研究中，依照结果，那些以正常或超正常血流动力学为终点的措施未能显示出益处，以混合静脉血氧饱和度为导向的研究同样如此。

We observed the effect of chronic hypoxia on intracelular levels of CGRP in pulmonary endocrine cells of SD rats by means of immunocytochemistry and supraoptimal dilution method.

我们用免疫细胞化学方法及超稀释法观察了慢性缺氧对SD大鼠肺中神经内分泌细胞内降钙素基因相关肽的含量的影响。

Syncope must be differentiated from epileptic seizures, although seizures due to brain hypoxia can occur in a syncopal episode.

晕厥必须与癫痫发作相鉴别，尽管在晕厥发作时也会发生脑缺氧引起的癫痫发作。

Methods: Endurance experiments include cold-resistant test , thermoresistance test , hypoxia resistant test and loading swimming test;Physical-biochemical indexes include hepatic glycogen content and lactic acid content in full blood.

耐力实验包括小白鼠负重游泳试验，耐热、耐缺氧试验及耐寒试验四个部分；生理生化指标观察包括测定肝糖原含量和全血乳酸含量两项。

The transudatory content of LDH had significant different (P.01) between the hypoxia-reoxygenation group and normal group, bear bile groups.

107.08士37.88林mol几。 LDH测定结果看出缺氧一再复氧组和正常组和熊胆组比较尸。01，具有统计学总义。

The intrapulmonary arteries especially arterioles are more important for vasoconstricting response to hypoxia , but it is very difficulty to isolate them from the lung.

我们以往通过对常压缺氧大鼠模型的肺组织和肺动脉肾上腺素受体(Adrenoceptor，AR)亚型及其基因表达的一系列研究，初步认为AR亚型基因表达变化在低氧性肺动脉高压发病中可能起重要作用。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
