骨痂

Hypertrophic nonunions have abundant callus surrounding the bone but a persistent radiolucent line at the fracture site.

肥大型不愈合骨四周大量骨痂，但是在骨折处可见持续的透明带，可以考虑其具有良好的生物学环境，但是缺乏足够的力学稳定性。

During osteoporotic fracture healing process ,the abnormal change of the organic constitution, microstructure, bone mineral metabolism and bone mass of callus could result in decrease of mechanical strength or quality of fracture healing which might be the main cause of refracture.

在骨质疏松性骨折修复过程中，骨痂组织的有机成份组成、显微结构、骨矿代谢与骨量的异常改变导致了其力学强度乃至骨折愈合质量的降低，是再次骨折发生的主要原因。

Influence of shock waves on fracture healing.

高能震波对骨痂中骨形成蛋白表达的影响。

After 12 weeks, the X ray density, the torsional moment and angle in failure load test and the score of callus in histological grading were all improved in the experimental side, compared with the control side. There was not statistically significant difference in both mature degree of bone union and growth degree of bone marrow.

动物在术后12周，实验侧X线片光密度测量结果，破坏载荷时扭矩和扭角测量结果均优于对照侧；组织学评分中，实验侧骨痂量评分优于对照侧，骨连接成熟程度和骨髓发育程度两者没有明显差异。

Results After 12 weeks, the X ray density, the torsional moment and angle in failure load test and the score of callus in histological grading were all unproved in the experimental side, compared with the control side. There was not statistically significant difference in both mature degree of bone union and growth degree of bone marrow.

动物在术后12周，实验侧X线片光密度测量结果，破坏载荷时扭矩和扭角测量结果均优于对照侧；组织学评分中，实验侧骨痂量评分优于对照侧，骨连接成熟程度和骨髓发育程度两者没有明显差异。

Twelve weeks following repair, coronal defect regions were filled with callus. 3D reconstruction showed that defects were repaired. Defect region and surrounding bony tissues had bony connection, with thick bone trabecula and mature Haversian system.

修复后12周，冠状位CT显示缺损区基本被骨痂填满，三维重建示缺损基本修复；缺损区域和周围骨组织形成骨性结合，骨小梁粗大，哈弗氏系统成熟。

And histomorphology of bony callus and bone cell formation.

骨痂组织形态学和骨生成细胞情况。

And the histomorphology of bony callus and bone cell production during fracture healing was observed.

并观察骨折愈合过程中骨痂组织形态学及骨生成细胞情况。

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。

Objective To observe the effect of compound material of transforming growth factor beta and rabbit cancellous bone on large cranial bone defects on ALP and calcium in osteal scab during large cranial bone defects healing process.

目的：观察转化生长因子β与兔骨松质的复合材料对兔颅骨缺损的修复过程中骨痂内ALP、钙的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
