Grade II CT signs resulted from various sites of occlusion, whereas grade III was unequivocally predictive of proximal occlusion to all of the lenticulostriate arteries.

The opening of leptomeningeal anastomoses vessel is the important way of collateral circulation in cases of serious stenosis or occlusion of MCA,the collateral flow between MCA and ACA is dominant. The RVACA/RVPCA can reflect the hemodynamic changes、the state of leptomeningeal anastomoses vessel when the MCA was serious stenosis or occlusion; There was a inverse correlation negative correlation between the RVACA/RVPCA and the NIHSS.

⑴在MCA中度以上狭窄或闭塞的情况下，皮质软脑膜吻合血管开放成为侧支循环的主要途径，以MCA-ACA之间的代偿为主；⑵RVACA和RVPCA在一定程度上可以反映MCA狭窄或闭塞时颅内血流动力学的改变、软脑膜侧支吻合的功能状况及有效程度；⑶RVACA和RVPCA与患者的NIHSS评分呈负相关，RVACA和RVPCA值越高的患者，其神经功能缺损程度越轻。

The middle cerebral artery occlusion/reperfusion rat model was established by the Longa occlusion method

参照Longa线栓法制作大脑中动脉阻塞再灌注动物模型

Results Among 6 cases with PCTPV, 4 cases revealed occlusion of the main branch of portal vein at the hepatic hilum, 2 cases revealed occlusion of the common portal vein, and a masslike network of tortuous veins around the hepatic hilum and many small irregular veins radiating from the network to the liver were demonstrated.

结果：6例中4例清楚显示门脉主要分支近肝门处阻塞，2例门静脉主干阻塞，代之以肿块样纡曲血管并在其周围形成向肝性放射状侧支血管影像，以及离肝性侧支循环静脉。6例CT血管成像均能对与分流或断流手术有关的血管解剖提供准确信息。

Type of occlusion, length of occlusion, ostial location and tapered morphology are factors on successful PCI.

闭塞病变类型、长度、有无开口及断端的形状是成功PCI的影响因素。

The inhibitory percentages of CD41 on the PAaR of post-occlusion was 43.25%, which was by far lower than the control PAgR of 72.48%(p＜0.001) before coronary occlusion

利用血小板聚集仪测定阻断冠脉前后血小板聚集的变化，比较CD41对缺血前后血小板聚集的抑制效应。

One or both sides pontocerebellar cisterna showed occlusion.conclusion occlusion or stenosis of fourth ventricle are the important reliable evidence in diagnosis of terminal transtentorial hernia.

脑桥小脑角池一侧或双侧闭塞。结论：第四脑室闭塞或狭窄是诊断晚期小脑幕裂孔下疝的重要征象。

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。
