Objective: The bridging veins emptying into superior sagittal sinus was observed by microanatomy and imageology, and then compared, to provide a basis for the preservation of the bridging veins during the interhemispheric approaches.

目的：通过对上矢状窦旁大脑桥静脉的显微解剖、影像学观察及其对照研究，为各种纵裂间手术入路中桥静脉的保护提供基础。

X-ray examination demonstrated that at 4 weeks after implantation, some or even lateral intertransverse bridging regions were unclear, and material density in the repairing group was lower than control group; at 8 weeks after implantation, interspace between up and down bridging was shrunk, and a great quantity of calluses were successively formed; at 12 weeks after implantation, complete confluence was observed, and the density in the repairing group was closed to that in the control group.

结果：采用脱蛋白处理后的松质骨可见大小不等、相互交通、开放孔隙的网架结构，孔径200~500 μm，孔隙率60%左右，其无机成分为羟基磷灰石，有机成分为胶原，力学性能保存良好，细胞相容性良好。X射线片结果显示：植入第4周，横突桥接处部分区域模糊，以内侧明显，此时修复组材料密度略低于对照组；第8周上下桥接部间隙变小，大量连续骨痂生成；12周后完全融合，两组材料密度接近。

Results: Anterior to the coronal suture and posterior to the lambdoid suture were two segments of SSS void of bridging vein draining into. The number of bridging veins observed by microanatomy, DSA and CTV was 11.2, 8.9 and 7.0 respectively.

结果：上矢状窦前部和后部分别有一缺乏桥静脉注入段，显微解剖、DSA和CTV观察上矢状窦旁桥静脉的数量分别为11.2支、8.9支和7.0支，DSA和CTV观察发现桥静脉注入上矢状窦处常显示不清。

Usually there are two bridging metho d s: static and dynamic. Static method is more efficient but not fit for a large s y stem, while dynamic bridging can be realized by virtue of dynamic mechanism, and in such a case only one bridging interface is needed, which is easy to be maint ained.

通 常，桥接有静态桥接和动态桥接2种方式：静态桥接效率高，但不适宜于大规模的系统；动态桥接采用动态机制实现，只需一个桥接接口，易维护。

To explore the regulatory mechanism of muscular ultramicrostructures of the outflow segments on blood flowing out from the cerebral bridging veins. Methods Bridging veins were obtained from patients suffering from nonvenous disorder diseases of the central nervous system.

目的 观察人脑桥静脉流出端管壁的肌性超微结构，揭示该段血管的收缩和舒张特性，探讨其对颅内静脉血液流出的调节机制。

In the thesis, a series of novel single and multi-armed oxadiazole bridging ligands and pyridyl-4, 5-imidazole dicarboxylic acid ligands have been synthesized. The coordination chemistry of these novel ligands with transition metal ions was investigated. In addition, two 1, 3, 4-oxadiazole bridging ligands end-capped by chelating Schiff-base coordination sites have been designed and synthesized. The coordination chemistry based on one of the two ligands with metal ions was primarily investigated.

Lund concept-to decrease the intracranial volume by the way of promoting the re-absorption of interstitial fluid in blood capillary bed-has been systematically studied too. But the investigation about cerebral vein system-the biggest blood storeroom-was less reported to review relative literatures. We carried out the pilot experiments to describe brain bridging veins in porcine and underlaid deeper research about human brain bridging veins by initially approaching possible ICP regulation mechanism.
