Methods Three hundred cm-long ileus tube was installed into jejunum by nasal cavity under radiophotography observation in 25 cases with recurrent postoperative adhesive ileus,ileus tube was impulsed by enterokinesia to ileum end to relieve adhesive ileus and conduct internal intestinal arrangement.

25例术后反复黏连性小肠梗阻患者，X线监视下经内置金属导丝的引导作用将300 cm长的肠梗阻导管经鼻置入空肠屈氏韧带20 cm以远，即刻小肠内抽吸减压，导管前气囊充水形成水囊，模拟食团在肠蠕动的推动下在小肠内移行，带动导管边吸引减压边向小肠远端前行，到达梗阻的直接上部抽吸减压或通过黏连部至回肠末端全小肠减压，解除肠梗阻。

With the id￠=0 vector control and the feedforward compensation of cogging, the minimum force ripple and maximum efficiency control of non-sinusoidal BEMF SPM motors can be obtained.

考虑永磁磁链谐波对永磁磁链导数矢量幅值及相位的影响，通过引入d￠q￠轴坐标系，提出一种id￠=0的非正弦波BEMF SPM电机矢量控制新方法，结合齿槽前馈补偿可以实现非正弦BEMF SPM电机的最小推力纹波最大效率控制。

Its outputs include the sigmoidal function to realize I-V nonlinear transfer and its derivative using the forward differential method.

它不仅产生S型函数，完成非线性I -V转换；还利用前向差分法，产生S型函数的导数。

Du Daozheng, once the head of China's state publishing watchdog, says he and the three other former officials transcribed recordings made by Zhao that were later turned into the recently published English-language book "Prisoner of the State."

在C臂X光透视机引导下用2~3枚1.5 mm导针钻入，对照术前X线和二维CT反复确认坏死病灶后，以3 mm空心钻钻入，于骨坏死区的股骨头软骨下骨5 mm处用50 mL注射器将浓缩的细胞悬液缓慢注入股骨头内。

As seen tod ay we still identify quite some of the traces of the traditional model in what are referred as school-based training, mentorship, practice-orientation, unification of pre-service education and in-service education, to mention but a few; while on the other hand, the British practices in school-based teacher training and the monitorial system are seen as representatives of the transcendent characteristics from conventions, and initiated the new perspectives in teacher education for the world to follow.

对传统的珍惜使英国人对已有的习惯具有某种难以舍弃的执拗，以致于在许多国家开始依托师范学校进行师资培养之后的很长一段时期，英国还固守着以"师徒制"为主要方式的教师在职培养，乃至今天英国教师在职教育的许多特点如"校本培训"、"良师制度"、实践取向、职前职后的"一体化"等都可以从早期的"导师制"中寻找到明显的"踪迹"；对传统的超越使英国教师的在职教育在"导生制"和"校本培训"等方面又开创了世界的"先河"。

It is learnt that the construction workers for the construction industry should purchase accident death, accidental disability, accident medical and third-party liability insurance, each insured person construction accident injury insurance amount not less than 10 million premium paid by the construction enterprises, construction workers to be assessed or covert enterprises assessed.

根据广东省建设厅和广东省保监局联合发出的《广东省建筑意外伤害保险工作导则》，要求各级建设行政主管部门和各级安全监督机构，将把工程项目开工前施工企业是否办理建筑意外伤害保险，作为审查企业安全生产条件的一项重要内容，未投保的工程项目，不颁发施工许可证。

Methods From January 2003 to October 2006, polysomnography was performed on 120 children with adenoidal hypertrophy before and after adenoidectomy. Various polygraphic parameters describing the macro- structure of sleep and the microstructure of sleep were analyzed.

对120例行腺样体肥大切除术的儿童，分别于术前及术后1个月行夜间睡眠多导监测，比较手术前后宏观、微观睡眠结构的变化。

Objective To observe the changes of suppression of nasal retina in the esotropic amblyopic eyes during the treatment of amblyopia by means of visual evoked potential.

目的应用VEP检测方法观察内斜视眼的鼻侧视网膜抑制现象在弱视治疗后的改变。方法对34例完全屈光性调节性内斜视弱视儿童治疗前及治疗3、6、9个月后进行一般视功能及多导图形VEP检测，并与24例正常儿童进行比较。

Aside from pancreatic enzymes activiation and autodigestive process, recent investigations have established that the upregulation of inflammatory mediator are believed to be the critical steps in the progression of mild pancreatitis to severe pancreatitis. Tumor necrosis factor-, ThyomboxaneA2 ,ProstaglandinsI2 are all important inflammatory mediator. TNF-( is one of cytokines. It is important to the over-production of ICAM-1,VCAM-1, TXA2 andPGI2. The ICAM-1 and VCAM-1 mediate both leukocytes adhesion and migration through the endothelium into tissues to connect with injuried target cells. The TXA2 and PGI2 are the production of arachidonic acid. They are responsible for the tissue ischaemia.

肿瘤坏死因子（Tumor necrosis factor-， TNF-、血栓素A2（ThyomboxaneA2，TXA2），前列环素（ProstaglandinsI2，PGI2）均是炎症反应中重要的炎性介质，其中肿瘤坏死因子-是非常重要的细胞因子之一，它由活化的单核细胞产生，在细胞间黏附分子（Intercellular adhesion molecule-1，ICAM-1）及血管细胞黏附分子(Vascular cell adhesion molecule-1，VCAM-1的表达、血栓素A2及前列环素过量生成方面起着重要的作用，前两者是介导白细胞与内皮细胞黏附，迁移于组织并与受损的靶细胞相结合的主要媒介，是炎症反应中的重要介质，后两者是花生四烯酸的代谢产物，亦是重要的炎性介质，参与构成血液循环障碍。
