The attenuation values at unenhanced and enhanced CT of the tumor were also recorded. Results The 32 cases adrenal neoplasms included 9 cases with aldosterone-producing adenoma, 5 hydrocortisone-producing adenomas, 1non-functional adenoma, 5 cortical hyperplasies,4 pheochromocytomas,2 adenocarcinomas, 3 metastases, 1 fibroneuroma, 1 ganglioneuroma and 1 myelolipomas. Conclusion The characteristics on CT images are associated with the pathological feature in adrenal neoplasms.

Ganglioneuroma is a benign neoplasm that is most commonly seen in the posterior mediastinum or retroperitoneum.

神经节瘤是一个良性瘤，大多常见于纵隔后或腹膜后腔。

BrdU labeling indicated that the positive cells in the lateral ganglionic eminence migrated in a similar way to those in control group 6 h following Xray irradiation, the positive cells were observed to be around the cystic cavities in cortexstriatum 2 days later and migrated to the ventral cortical plate 4 days later.

BrdU标识显示腹侧端脑的外侧节隆起的神经细胞移动类似于正常对照组，2 d后阳性细胞分布在皮质纹状体区形成的空洞周围，4 d后移动到腹侧皮质板。

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.

应用椎弓根外内固定技术2004/2007年在中山大学附属第三医院骨科治疗34例患者，固定前采用CT加密扫描测量进钉点、进钉点至椎体前缘的深度、进钉角度和直径，固定中椎弓根钉入点为横突尖，进钉方向为平均向头侧倾斜10°~20°、与中线成角30°~40°，顺椎弓根外侧皮质进入椎体，固定后CT加密扫描观察螺钉周围的皮质骨是否完整、是否靠近节段血管、是否穿透皮质骨，评价置入钉的准确性和安全性。34例患者共置入160枚胸椎椎弓根螺钉，固定后CT加密扫描和X射线片观察到148枚(92.5%)螺钉置入准确，12枚(7.5%)螺钉发生错置。

Results There were 22 lacunar infarction cases, 1 case large area infarction, and 8 cases with small bleeding in the thalamus, 1 case with large bleeding in the basal ganglia of 9 cases intracerebral hemorrhage. Hemichorea appeared in 27 cases within 24 hours, 5 cases within 1 week. All received aloperidin, the symptom disappeared in27 cases（84.4%）.

结果 32例偏侧舞蹈症病例中脑梗死23例(腔隙性脑梗死22例，大面积脑梗死1例)，脑出血9例(丘脑少量出血8例，基底节区大量出血1例)；脑卒中后24h与1周内出现偏侧舞蹈症症状分别为27例和5例；应用氟哌啶醇治疗后症状消失27例。

Objective To investigate the feasibility and effectiveness of radiofrequency ablation for the treatment of secondary splenomagely and hypersplenism in dog.

RFA后的脾脏CT病灶呈节段性毁损，包括高密度的坏死区和低密度的梗死区；梗死区在RFA后 4～ 6周内消失。

Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

METHODS: The stability of intact specimens in flexion, extension, lateral bending and torsion was examined. A fracture model was created using dropping technique. The fracture model was instrumented with short-segment pedicular screw fixation (4-screw construct) or the intermediate screws structure (6-screw construct).

测量完整标本前屈-后伸、侧屈及旋转的稳定性后，通过重物撞击技术制造伤椎骨折模型，然后对每个标本行传统短节段椎弓根螺钉固定（4枚螺钉固定）及增加骨折椎椎弓根螺钉固定（6螺钉固定）。

Results Meckel cave was a dural recess extending from the posterior fossa to the posteromedial portion of the middle ...

结果Meckel腔是由颅后窝向颅中窝后内侧部分突入的硬脑膜陷凹，腔内容纳三叉神经半月节和三叉池。

Results: In non-LAD segments: there were no change of postsystolic strain E(subscript ps during ischemia and infarction compared with baseline, nor after adenosine is administered.

结果：非LAD节段：于缺血及梗死状态下收缩期后收缩的应变E(下标 ps较基础状态差异无显著性意义，应用腺苷后较用药前差异无显著性意义。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
