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）。

Methods A case report was madeon a 55 years old man who suffered from disorder of speech and impairment of verbal short-term memory after ischaemic infarction of the left posterior lentiform nucleus. The patient had been examined by using MRI and cognitive tests.

And (20. 5 ± 1.7) ml· 100 g-1 ·min-1, respectively. When compared in 3 groups, the temporal and parietal lobe rCBF had a decreasing tendency in aMCI group, while in VCI-ND group, the most dominant decreasing parts were mainly concentrated in white matter region (17. 7±2. 3 ml·100 g-1·min-1, F = 5. 740, P = 0. 002. Whatever the depth or the width was, beth periventricular and subeortical deep white matter, anterior and posterior ventricular regions were all involved. There are no dominant difference of rCBF in caudate nucleus, lentiform nucleus and thalamus.

2NC组、aMCI组和VCI-ND组患者的rCBF表现比较：aMCI组颞、顶、枕叶的rCBF值呈一定趋势的减少，VCI-ND组额叶的rCBF值呈一定趋势的减少，而VCI-ND组rCBF下降最明显的部位集中在白质区域[(17.7±2.3)ml·100 g-1·min-1，F=5.740，P=0.002]，从深度看覆盖了脑室旁白质和皮质下深部白质两部分，从长度看覆盖了白质的前后区域。3组基底节区核团包括尾状核、豆状核和丘脑的rCBF值比较差异无统计学意义。

Results Mini-Mental State Examination showed that patient had impairments of rehearsal, expression and verbal short-term memory. Chinese Rehabilitation Research Center Standard Aphasia Examination revealed he had difficulties in expressing and writing. Test for immediate recall of verbal stimuli showed moderate impairment in the patient. MRI indicated there was ischaemic infarction in the left posterior lentiform nucleus.

结果 简易智能状态检查患者表现在语言复述、表达及短程记忆方面障碍；中国康复研究中心汉语标准失语症检查量表检查提示主要表现在语言的表达和书写的障碍；词语短时记忆检查提示中等损害；影像学检查显示左侧豆状核后部缺血性梗死。

However, significant differences in ADC in different diffusion gradients were found within normal human brain parenchyma, which including caudate nucleus, lentiform nucleus, centrum semiovale, posterior limb of internal capsule, and corpus callosum, except the thalamus.

而除丘脑外的正常脑灰质团块及白质（半卵圆中心、内囊后肢、胼胝体膝部和压部）的ADC值在不同扩散梯度方向上存在显著性差异（P≤0.05）。

Methods the size,shape of the posterior cranial cavity and infratentorial brain structures on mid-sagittal mr image was measured in 19 patients had the kind of cervical vertebra sickness symptoms and the latter group cranial nerve symptoms,and another 19 patients of matching age and sex but lacking the corresponding symptoms and signs were selected as the comparison group.two groups all deleted chiari abnormal and lepospondylous occipital arthrosis abnormal.

对19例有类颈椎病症状和后组颅神经症状的患者测量mr正中矢状位后颅腔大小形态和幕下脑组织的大小形态，选择19例年龄、性别相匹配而缺乏相应症状和体征的患者为对照组。

Results of 131 patients, 94（71.8%） with posterior canal involvement were randomly divided into 2 groups and treated with canalith respositioning procedure and semont liberatory maneuver, respectively.

These 3 characteristics are:(1) injury morphology as determined by the pattern of spinal column disruption on available imaging studies,(2) integrity of the disco-ligamentous soft tissue complex represented by both anterior and posterior ligamentous structures as well as the intervertebral disc, and (3) neurologic status of the patient.

该系统提出将3个主要的损伤特征作为诊治下颈椎损伤的指征，包括：（1）脊柱影像学上的损伤形态，（2）以前纵韧带、后纵韧带和椎间盘为代表的间盘韧带软组织复合体（discoligamentous soft tissue complex DLC的完整性，（3）患者的神经系统状态。

However, the authors contend that a thoracolumbar burst fracture, in exclusion of an associated posterior ligamentous complex injury, is inherently a very stable injury and may not require a brace.

但是，笔者认为不伴有相关后韧带复合性损伤的胸腰粉碎性骨折原本是一种稳定的损伤，无需矫形器治疗。
