Selected anastomosis site:The site for the attempt at anastomosis creation was chosen at least 2-3 disc diametersaway from the optic disc or 1 disc diameter peripheral to the occlusion site in eyes with bruch retinal vein occlusion, and a large underlying choroidal vein by showing in ICGA, usually in the inferior fundus.

激光吻合：在选定的吻合部位，用选定的高能量激光先击射邻近的＊＿Ch膜，接着是静脉壁本身，Bruch膜破裂的疑似迹象，为一汽化泡，当静脉壁破坏时有微量的出血。37例RVO共做了86个吻合点，所用的激光参数为：光斑直径50p，曝光时间 0.l秒，使用绿光最多 63个点（72％），功率 800～900mw，少数用氟红、氟黄及Nd：YAG激光。

This is not ambient occlusion as in the usual definition, but it indeed gives some kind of concavity for the shaded point, what can be interpreted as an occlusion factor.

这不是通常所说的环境遮挡的定义，但是它确实给这个着色点带来了一些凹凸感，我们可以把它解释成遮挡系数。

Cases had non-isolated splenic vein occlusion, including 6 cases with interruptive thrombosis in PV-SV-SMV junction and 3 cases with stenosis or occlusion near PV trunk and SMV. 30 cases had been combined with twist vein collateral circulation and 6 cases with portal hypertension.

Results Critical stenosis or occlusion of contralateral arteries were found in the siphonic part of internal carotid artery in 6 patients, terminal ICA or proximal middle cerebral artery in 6 patients, and distal MCA in 1 patient. Seven patients had proximal ICA occlusion. The brain MRI showed typical watershed cerebral infarctions in 8 patients.

结果 所有患者均存在对侧颅内外血管严重狭窄或闭塞，其责任血管分布：颈内动脉虹吸段6例；颈内动脉末端或大脑中动脉起始部6例；大脑中动脉的M2段1例；颈内动脉起始部7例。8例头颅磁共振显示典型的分水岭脑梗死。6例行血管重建治疗，临床未再发作。

METHODS: Male Wistar rats were randomly divided into 4 groups: in sham group, only anesthetization and operation were performed; in MLR group, occlusion of mesenteric lymphatics for 1 h followed by 2 h of reperfusion; in SMAO group, occlusion of superior mesenteric artery for 1 h followed by 2 h reperfusion; in MLR+SMAO group, occlusion of SMA and ML for 1 h followed by 2 h of reperfusion.

Wistar雄性大鼠均分为4组：sham组，仅麻醉与手术；MLR组，夹闭肠系膜淋巴管1 h，再灌注2 h；SMAO组，夹闭肠系膜上动脉1 h，再灌注2 h；MLR+SMAO：夹闭ML和SMA1 h，再灌注2 h。

However, grade II CT signs did not always result from type 2 occlusion; 21.1% of patients with grade II CT signs had type 4 occlusion. When the MCA trunk is short, the lateral group of the lenticulostriate arteries may arise from the M2 segment[2, 12]. In such cases, type 4 occlusion may also involve the lateral or posterior part of the putamen.

但是，II级早期CT征象（部分壳核后外侧区出现低密度）并非仅仅由2型大脑中动脉闭塞（包括部分豆纹动脉在内的大脑中动脉主干闭塞，豆纹动脉部分受累）引起；本研究中，21.1%深部大脑中动脉分布区出现II级早期CT征象（部分壳核后外侧区出现低密度）的患者，是因4型大脑中动脉闭塞（大脑中动脉M2段闭塞）引起的；这些患者的大脑中动脉主干均很短，因此外侧豆纹动脉群（lateral lenticulostriate arteries）是由大脑中动脉M2段发出的；此时，4型大脑中动脉闭塞（大脑中动脉M2段闭塞）也可以导致壳核后部或外侧部出现低密度（深部大脑中动脉分布区II级早期CT征象）。

PART 1 EXPRESSION OF MMP/TIMP IN SKELETAL MUSCLE OF ARTERIAL OCCLUSION DISEASE MODELS OF DOG'S HIND LIMB Objective To study the distribution changes of typeⅠand typeⅢcollagen in skeletal muscle of arterial occlusion disease models of dog's hind limb and the expression of MMP-2/TIMP-2 in skeletal muscle of arterial occlusion disease models of dog's hind limb.

第一部分MMP/TIMP在犬后肢动脉闭塞性病变模型骨骼肌中表达的变化目的研究Ⅰ型胶原、Ⅲ型胶原在犬后肢动脉闭塞性病变模型骨骼肌的分布变化以及MMP-2、TIMP-2在犬后肢动脉闭塞性病变模型骨骼肌表达的变化，探讨胶原代谢和基质金属酶系统在缺血导致的骨骼肌重塑中的意义和作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

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。
