Stenosis of internal caroid antery was found in 32 of 48 branches in 24 case. 5 branches were occlusive and 11 branches were normal. 22 cases with large or moderate cerebral infarction volume （＞5 cm3） confirmed by CT and MRI were smaller than those on MSCTPI as having abnormal perfusion lesions,which were moderate and obvious stenosis and occlusion on MSCTA. In 2 cases with small cerebral infarction volume（＜5 cm3）, MSCTPI and MSCTA revealed normal.

其中32支颈内动脉呈不同程度的狭窄，5支颈内动脉闭塞，11支血管无狭窄。22例在常规CT及MRI图像上为中及大体积梗死（＞5 cm3）的患者，MSCTPI发现与梗死灶相对应的异常灌注区，且均比常规CT及MRI图像上病灶体积大， MSCTA显示颈内动脉呈中重度狭窄或闭塞。2例未发现明显灌注异常的患者，为小体积梗死灶（＜5 cm3），MSCTA显示颈内动脉正常。

On the other hand, because the insular region is mainly supplied by the M2 segments, only loss of the insular ribbon without obscuration of the lentiform nucleus may be usually seen in type 3 or type 4 occlusions. Although there are few exceptions of type 1 occlusion manifesting a grade I CT sign in the very early period of ischemia, grade I CT signs are usually considered as supporting evidence of absent lenticulostriate artery involvement.

尽管在缺血性卒中发病后的超早期，1型大脑中动脉闭塞（大脑中动脉主干起始段闭塞）患者的深部大脑中动脉分布区可能偶尔也会出现I级早期CT征象（细微低密度区局限于岛叶，基底节区正常）；但深部大脑中动脉分布区I级早期CT征象（细微低密度区局限于岛叶，基底节区正常）的出现，通常提示豆纹动脉未受累。

An occluded corrosion cavity simulated cell was designed,and electrochemical impedance spectroscopy and polarization curves measurement were employed to study the effect of MoO42- on the development of underscale local corrosion of carbon steel in neutral NaCl solution.

设计了一种能够模拟垢下局部腐蚀自催化过程的闭塞电池，采用极化曲线和电化学阻抗方法研究了MoO42-对N80钢在近中性NaCl溶液中闭塞区内化学及电化学状态变化的影响。

Fourpatientswere diagnosedfree ofASO,and 55 patients exhibited discontinued sclerosis orblock of lower extremity arteries around whichwere plenty ofblood-supply peripheral arteries.Conclusion 64-slice CT angiography can display the featuresof lower extremity arteries clearly,such as vasiform,arterial stenosis degree,occlusion and calcified plaque.

64层螺旋CT血管成像检查可清楚地观察下肢动脉的血管形态及管壁的钙化斑块，了解下肢动脉狭窄程度及闭塞情况，对下肢动脉硬化性闭塞性病变的术前评价、诊断和筛选有较大的帮助。
