Objective:To study responses of skeletal in patients with chronic arterial occlusive disease to ischemia reperfusion injury.

目的：研究慢性周围动脉闭塞患者骨骼肌对旁路术中缺血-再灌注损伤的应答。

Background: Limb salvage is considered the primary goal of management of peripheral arterial occlusive disease, especially in patients with critical limb ischemia.

The corresponding change of the blood flow of the ophthalmic arteries takes place when the internal carotid artery stricture lead to acute cerebral ischemia. The Vmean, Vmax, RI, PI of the ophthalmia artery showed significant reduce, but the change of Vmin was no difference.

当颈内动脉狭窄引起脑缺血时，眼动脉与脑动脉发生相似的血流动力学改变，眼动脉的平均血流速度、最大血流速度、阻力指数、搏动指数较前均明显降低，而最小血流速度不发生明显改变。

Atherosclerosis involved progressive luminal narrowing until the blood flow was compromised to the point that organ metabolic needs could no longer be met, producing ischemia and infarction of the subtended tissue such as the heart or the brain.

D 斑块破裂：早期，对於动脉粥样硬化症的观念涉及到动脉腔变得愈来愈狭窄，直到血流有障碍而不再能够满足器官新陈代谢的需求，而导致对向组织的局部缺血与梗塞，例如心脏或脑部。

Forty adult female rats were divided randomly into 4 groups:① Pseudo-operation control group: no ovariotomy, no common carotid artery occlusion;② Cerebral ischemia reperfusion group: with CCAO only, no OE;③ Ovariotomized control group: with OE and CCAO, no estradiol;④ Estradiol supplement group: with OE, CCAO and estradiol supplemented (30 d after ovariotomy, estradiol was supplemented every day for 14 d). All the rats were sacrificed after 12h of reperfusion injury, 10% of brain tissue was homogenized and 10% alue was determined by UV spectrophotometer, NO content was detected, and frozen sections and NOSmRNA in-situ hybridization were performed.

取SD大鼠40只随机分为4组：①假手术对照组：不切除卵巢，不夹闭颈总动脉；②脑缺血再灌注组：作局灶性脑缺血再灌注手术，不切除卵巢；③去卵巢对照组：切除卵巢，作局灶性脑缺血再灌注手术，不补充雌激素；④补充雌激素组：切除卵巢，作局灶性脑缺血再灌注手术，补充雌激素（切除双侧卵巢30d开始补充雌激素，连续2周）。

However, a growing number of studies suggest that excessive extracellular glutamate and resultant overstimulation of its receptors cause excitotoxic roles and lead to neuronal damage in several pathological conditions such as cerebral ischemia. Normally, the excitatory postsynaptic roles of glutamate are terminated by the activities of high-affinity sodium dependent glutamate transporters that locate on neuroglial cells and neurons near the synaptic cleft, which are thought to play important roles in inactivating released glutamate and keep it below toxic levels in the extracellular space.

在生理状态下，突触间隙中谷氨酸的清除取决于邻近神经胶质细胞及神经元上高亲和力、钠依赖性谷氨酸载体的活动，通过该载体的再摄取机制保持细胞外谷氨酸浓度于正常范围，这在预防谷氨酸的神经毒中起着重要的作用。

Ischemia necrosis: death of tissue due to loss of oxygenated blood to an area of the body.

缺血性坏死：死亡的组织中，由于亏损的含氧血液，以一个地区的机构。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
