In SMC group, relative stable of the both ends of fracture reduce unnessary repeated stimulation of injury, and at same time, axio-stress advantageous for preosteoblast and mesenchymal cell transmit to osteoblast and chondroblast. Material and design superiority of SMC form unique internal mechanical environment, and which benefit for bone healing. The study took deep investigation of SMC on fracture healing.

上述结果证实：SMC内固定可对骨折端施加主动的、持续的轴向应力刺激，形成沿长骨骨干轴向的成骨导向力值，配合环抱翼的把持作用，形成了区别于CP、IN的独特的稳定、有效的机械内环境，骨折端的相对稳定减少了不必要的损伤再刺激，同时持续轴向应力有利于成骨祖细胞、间充质细胞向成骨细胞和成软骨细胞转化、促进了成骨诱导过程的发生与发展，加快了骨折愈合的修复与重建。

In the second group,the rabbits were treated only with the argon laser induced chorioretinal venous anastomosis. Results An anastomosis in experimental group was formed in 6 rabbits within 4-6 weeks after treatment while no anastomosis was formed in control group.

结果：通过眼底荧光血管造影检查和彩色眼底照像，实验组6只眼成功建立视网膜脉络膜吻合，检眼镜下激光击射部位静脉中断呈漏斗状陷入脉络膜；FFA显示远端及近端静脉内血流汇入吻合处，吻合形成时间为4~6周，对照组未形成吻合。

Objective\ To find out a good method to reduce or eliminate the chylothorax after resection of esophageal carcinoma.

目的 寻找减少或消除食管癌切除术后乳糜胸发生率的有效方法。方法随机选取 45例食管癌患者，在食管癌切除加胃食管残端吻合时，一期行预防性低位胸导管结扎术(第 8胸椎水平以下)；另 92例作对照组，仅做食管癌切除加胃-食管残端吻合术。

The device comprises retaining means for keeping the lid (2, 3) in place in a sealing manner during treatment, and the retaining means comprise a bounding frame (10) that is circumferentially closed, with two interconnected end pieces (11, 12) situated at a distance from each other, which end pieces in a closed position can be slid over the pressure vessel (1) and thereby retain the end faces of the pressure vessel (1) in the axial direction.

Proximal dendrites of hippocampal CAI pyramidal neurons receive mainly the inputs from schaffer collateral/associational commissural pathways, whereas the distal dendrites receive mainly the inputs from entorhinal cortex through TA pathways.

由于近端树突接受海马内部侧枝／联合纤维投射的信息，远端树突通过TA通路接受内嗅皮层投射的信息，由此提示，CA1区锥体细胞对来自海马内部和直接来自皮层的信息输入采用了不同的整合方式。

The utility model discloses a magnetic lift device which comprises a main magnetic lift part, a rotating pole bracket, a transmission supporting saddle, a left rotating pole and a right rotating pole. A turning plate yoke device is arranged on the upper surface of the main magnetic lift part, and the turning plate yoke comprises a yoke head, a yoke head base, a constringent spring, a pulling rope as well as a rope sling.
