Objective To investigate the relevance between dissection characteristic and the partial nerves symptoms and signs by measuring the dissection relations of posterior cranial cavity,infratentorial brain tissue,cerebellum tonsil as well as inferior foramen occipital.

目的 运用MRI的方法测量后颅腔、幕下脑组织以及小脑扁桃体和枕骨大孔之间的解剖关系，进而探讨这种解剖特征与部分神经症状和体征的相关性。

Methods the angles from the body surface of yamen (gv 15) to the joint line between the level opposide atlas and axis, and the joint line between body surface of yamen point and posterior margin of the great occipital foramen, upper margin of arcus posterior atlantis were measured respectively in 1120 cases of t1 weighted image of median sigittal position with mri, and the data were processed by computer.

取1120例mri正中矢状位t1加权像，分别测量体表哑门穴至水平相对寰、枢椎椎间的连线与体表哑门穴至枕骨大孔后缘连线、寰椎后弓上缘连线所夹的角度，并由计算机进行数据处理。

Using 2MHz pulseultrasonic Doppler probe, the index of hemodynamics such as blood flow rate、audio frequency、vascular pulsation of bilateral vertebral and basilar arteries were detected in order to analyze the diagnosis of cervical spondylosis involoving vertebral artery by Transcranial Color Doppler through the occipital foramen. Results: of all 108 carses, 80 cases were positive(positive rate 74.7%). In CSA group,cases of low flow rate were 45.6%,cases of high flow rate were 28.7%,and cases of no...

为分析经颅多普勒检测椎动脉型颈椎病的诊断价值，采用配对研究方法，用 2MHz脉冲多普勒探头经枕骨大孔窗口，检测左、右椎动脉及基底动脉的血流速度、流向、音频、血管博动指数等血流动力学指标，结果显示 10 8例患者有 80例异常，异常率 74 7%，并发现CSA组低流速者占 45 4 %，高流速者占 2 8 7%，正常流速者占 2 5 9%，与正常对照组间有显著差异(P 0 1)，总体而言，低流速型是CSA的主要特征之一。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
