Results: The occludes were successfully deployed in 23 patients. Trivial residual shunt was found by left ventricular angiographies immediately after occlusion in 2 patients, only one case had trivial residual shunt after 6 month follow-up. There were no detached device、embolism or other complications.

Methods A total of 10 cases of gliomas in eloquent cortex were resected under cutaneous nerves block anaesthesia in complete consciousness. The patients were monitored for language cortex localization by phonated number counting during the craniotomy.

选择位于语言功能区的脑胶质瘤患者10例，实施头皮神经干阻滞麻醉后全程清醒开颅手术，切除肿瘤中维持患者进行出声连续计数的语言功能监测，使尽可能全切肉眼可见肿瘤而保存功能脑区。

The paper also points out that, modern logistics can restructure and upgrade the regional industries by means of the effect of industrial relevancy when it serves for the social production and residents living, engenders new industries and enhances the internal proportions of the third industry. By integrating related functional operations, modern logistics is able to change the links between the knots and lines from random and loose connection to a kind of spatial structure of smoothness and steadiness, with which block and friction would be lessened and the function of regional economic constituents amplified while the regional income and the strength would be improved as a whole. Through intensifying the advantage of allocation of the centers of region, modern logistics induces regional elements of development to move towards advantageous locations while bringing key urban cities effects of scale economy and agglomeration economy, it then can be regarded as an operational platform for potentiating the growing polar of urban cities and boosting up the developing level of hinterlands, and an effective measure to balance urban and rural development and development among regions.

论文认为，现代物流在为社会生产和生活服务、形成新的产业形态、改善第三产业内部比例关系的同时，通过产业关联带动效应促进区域整体产业结构的优化升级；现代物流通过整合相关功能性活动，将经济网络中节点与线路之间随机连接、松散联系转变为顺畅交流、稳定合作的空间构造，从而减少区域经济运行中的阻滞性因素，放大区域经济发展要素的功能，提高区域经济系统整体效益和经济实力；现代物流通过强化经济中心的区位优势，促进区域经济发展要素向优区位运动，给经济中心城市带来规模效应、聚集效应和扩散效应，是强化中心城市增长极地位和提升经济腹地发展水平的操作平台，因而也是统筹城乡发展和区域发展的重要手段。

Methods: Forty ASAⅠprimiparas, aged 26-32 years, weighing 70-90 kg, height 150-170 cm, with 37-39 week gestation, underwent elective cesarean section with CSEA, were enrolled in this study.

择期脊椎-硬膜外联合阻滞下行剖宫产术患者40例，初产、ASAⅠ级、年龄26～32岁、体重70～90 kg、身高150～170 cm、孕周37～39 w。

It was found that the students use twelve different methods, including combining | facts and experiences, using anomalies, using analogies, rebutting, comparing and contrasting, elaborating, causal-effect reasoning, using investigations, making judgments, referring to authorities or textbooks, resorting to innate properties, and introducing terminology to talk about science. In addition, three categories of methods can be identified according to the patterns and trends of talking episodes.

研究发现指出，学生呈现「结合事实或经验」、「利用反证解说论点」、「类推」、「思辩」、「比较」、「论点再精致化」、「推论因果关系」、「建议以动手做结果来验证」、「判定不同的论点或主张」、「引证书本或他人知识」、「生物特性」以及「引入科学名词」等十二种对谈类型；且学生参与对谈的类型会导致对谈呈现扩展失焦、深入论证或阻滞不前等三类不同的发展趋势。
