The experimental study is to explore the effect about rhEPO on neuromotor function, secondary pathology change and expression of NTF and the apoptosis of neural cell, which administered at different time after traumatic spinal cord injury. The experimental study is devided into three parts: The first part The effect of rhEPO on NT-3 and NGF expression after traumatic spinalcord injury Objective Nerve growth factor and neurotrophic factor–3(NT-3) are chief members in neurotrophic factors family, which can promote nerve cell survival、growth and differentiation.

本研究拟在脊髓损伤后不同时间应用促红细胞生成素干预，探讨其对神经运动功能和继发性病理改变的保护作用及对神经营养因子表达和神经细胞凋亡的影响，共分为以下三个部分：第一部分脊髓损伤后促红细胞生成素对NGF、NT-3表达的影响目的：神经生长因子和神经营养因子-3(NT-3)是神经营养因子家族的主要成员，是机体产生的能够促进神经细胞存活、生长、分化的一类多肽或蛋白质因子。

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。

Endurance training increased the activity of iNOS in liver , thereby in2 creasing the level of NO , but the high level of NO didn' t result in the oxidative injury of the liver. I t indicated that the protection or oxidative injuri of nitric oxide in nonalcohol fatty liver was closely related to the physiological state of life.

耐力运动引起非酒精性脂肪肝小鼠肝脏iNOS活性升高，导致 NO水平升高，而高水平的 NO并未造成肝脏的氧化损伤，说明 NO水平的升高并不一定造成氧化损伤，其是否具有氧化损伤作用与机体的生理状态有关。

Objective: An open-label noncontrolled study was conducted in subjects with increased oxidative stress burden to evaluate the mental and physical effects of antioxidant astaxanthin.

日本同志社大学抗衰老医学研究中心和富士化工合作的一项研究表明，天然虾青素可提高机体抗氧化能力、降低血压，减少下肢血管阻力，改善高氧化应激下妇女的身体症状。

Or white blood cell; a colorless blood corpuscle capable of ameboid movement, whose chief function is to protect the body against microorganisms causing disease and which may be classified in two main groups: granular (granulocytes: basophils, eosinophils, neutrophils) and nongranular(nongranulocytes: lymphocytes, monocytes).

或称白血球，为一能作变形运动的无色血细胞，其主要作用是保护机体抗御致病菌。它可以分为两大类：粒性（粒性白细胞：嗜碱粒细胞、嗜酸粒细胞、嗜中性粒细胞）和非粒性（非粒性白细胞：淋巴细胞、单核细胞）。

objective to study the risk factors on esbl producing strains of k.pneumoniae and e.coli.methods aprospective survey on esbl producing strainsof k.pneumoniae and e.coli for a36-month period.results the resistance rates ofe.coli were:98.08%for ctx,73.08%for amc.the resistance rates of k.pneuˉmonialwere;95.74%for ctx,97.87%for amc.the use rate of third generation cephalosporins was much higher than those of esbls nonproducing strains（p.05）.it induce esbls that3rd generation cephalosporins were used extensive.after strenghtening the antibiotic controls,esbls detection rate has gone down.conclusion the factors of infection of esbl-producing strains were the severity diseases,cellular immunological condition,improper medical manipulations.to prevent esbl-producing strains,reasonable antibiotics usage may be the effective measure.

目的 分析临床大肠埃希菌及肺炎克雷伯菌产esbls的危险因素，并加以控制。方法前瞻性监测产esbls菌的情况，并对感染者进行临床调查。结果产esbls的大肠埃希菌、肺炎克雷伯菌的耐药率头孢噻肟钠为98.08%和95.74%，阿莫西林+棒酸为73.08%和97.87%，产esbls菌感染者头孢第三代的使用率（70.21%）显著高于非产esbls菌感染者（39.47%）（p.05）；第三代头孢的大量使用诱导esbls的产生。通过加强抗感染药物的使用管理esbls检出率开始下降。结论严重的基础病、高龄、机体免疫力低下，长期住院者是esbls菌感染的易感宿主，皮质激素、化疗及介入性疗法是esbls感染的高危因素。滥用抗感染药是产生esbls的重要因素，合理使用抗感染药是防止esbls产生的主要措施。
