EGFL7 protein is a factor specially secreted by the endothelial cell. It is necessary for formation of vascular lumen, the formation process would be blocked and functions of vascular is incompleted if it is missing.

论文摘要： EGFL7蛋白为一种内皮细胞特异性分泌因子，它是血管管腔形成所必需的因子，它的缺乏将导致管腔形成受阻，从而影响血管功能的完善。

Histology showed that control group had massive cartilage cell gathering together and bone trabecula disturbance, it had no significant bone cortex and medullary cavity formation.

组织学检查显示：对照组中可见大量团聚软骨细胞、骨小梁紊乱，无明显骨皮质、髓腔形成。

Fig 1 At the experimental side, two weeks after operation (HE ×100) Many pieces of cartilage cells and spindle-shaped mesenchymal cells were found, by light microscope Fig 2 At the experimental side, twelve weeks after operation (HE ×100) Medullary cavity had formed, which contained hemoblasts and adipocytes, but the trabculae was not typical, by light microscope Fig 3 At the experimental side, twenty-four weeks after operation (HE ×100) The typical cancellous bone had formed, by light microscope Fig 4 At the control side, twenty-four weeks after operation (HE ×100) A large part of CXB was degraded, resorbed and replaced by fibrous tissue, but there was'not any new formed bone, by light mocroscope

图1 实验侧术后2周(HE ×100)镜下可见很多软骨细胞条索和团块生成及大量梭形间充质细胞图2 实验侧术后12周(HE ×100)镜下可见有髓腔形成，内含有造血和脂肪细胞，骨小梁尚不典型图3 实验侧术后24周(HE ×100)镜下可见形成典型的松质骨结构图4 对照侧术后24周(HE ×100)镜下可见大部分CXB被降解吸收，为纤维组织替代，无新骨形成

How big a macrocycle should be for threading to occur is a basic and important question in threaded structure chemistry.

在互穿结构化学中，客体二级铵盐究竟最小能穿过多大的冠醚环的空腔形成互穿结构是一个基本但非常重要的问题。

This thesis included three parts:(1)The study of the complexation and threaded structures based on the benzo-21-crown-7/secondary dialkylammonium salt recognition motif;(2)Secondary dialkylammonium salt can thread through the cavity of pyrido-21-crown-7 to form the threaded structures;(3)The study of the size of macrocycle rings which can complex with secondary dialkylammonium salts.

本论文主要开展了以下三方面內容的研究：(1)基于苯并21-冠-7(B21C7)的主体冠醚和二级铵盐客体化合物的络合以及互穿结构研究；(2)客体二级铵盐穿过吡啶-21-冠-7(P21C7)的空腔形成准轮烷及轮烷互穿结构的研究；(3)对关于络合二级铵盐的冠醚环的尺寸大小做了探讨。
