骨痂形成

Over the last fifty years, ultrasound has also been studied in relation to the stimulation of bone callus.

在过去50年里，超声波在刺激骨痂形成方面的作用也曾被研究过。

The union time was5-13months.14patients got bonyunion,normal function and figure,completely loading without deformity;1patients got poor callus development,after a series of treatment,such as coaptation,osteopractic et al,delayed union was obtained.

骨折愈合时间5～13个月。14例达骨性愈合，功能正常，患肢无畸型，负重无疼痛不适；1例骨痂形成欠佳，后经补钙接骨、局部注射金葡液等治疗，骨折延期愈合。

At early stage after brain injury, there were a quantity of fibrous callus and cartilaginous callus formation in brain injury and fracture group and many neuropeptides immunoreactive nerve fibers in callus were found. Strong immunoreactivites of CGRP, SP, VIP, NPY, TOH occurred to osteogenitor cells and chondroblast, which proliferated in thickened endothecium.

脑损伤合并骨折组早期形成大量纤维骨痂和软骨骨痂，骨痂中神经肽免疫阳性神经纤维较多，明显增厚的骨膜内层骨祖细胞、幼稚的软骨细胞胞质内降钙素基因相关肽、P物质、血管活性肠肽、酪氨酸羟化酶、神经肽Y强阳性表达。

All iliac hone graft fused well and a great deal of bony callus was found the vertebral body surface. Lucency area was in seen surrounding the hone graft, titanium and AC-AFF on the X-ray films, and there wan new bone formation in the interface of internal union and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary aim of implants by CT scan. And port of the new hone transited the parietal reticulation and connected with normal ones at titanium and AC-AFF.

髂骨植骨组融合情况良好，融合界面上有较多的骨痂生成。X线摄片见植骨块、钛网、AC-AFF中空区域模糊且有骨组织生长，内植物周围无透光带存在，植骨界面上有骨桥形成；CT扫描在钛网及AC-AFF组可见内植物腔内形成的新骨通过其四壁的网眼结构与周围骨质相接，说明所有标本均达到骨性融合，但其中以AC-AFF组形成的新骨数量为多，且较为成熟。

While in the BMP/HA group, although the fibrous callus was appeared in the 4th and 8th weeks, the HA was not absorbed. In the 12th and 16th weeks the change was similar to that in the 8th week and no recanalization of bone marrow cavity.

而BMP/HA复合组，虽然在第4、8周也有纤维性骨痂形成，但HA不被吸收；第12、16周与第8周相似，无髓腔再通现象。

The Pyrolusite Power Preparation for Infusion group can promote the healing of the osteoporosis fracture effectively , its function mechanism is:1, Improve the density of bone of the osteoporosis big rats of fracture;2, Improve the content of bone scab calcium , phosphorus , collagen;3, Promote the bone scab to be ripe.

无名异冲剂能够有效促进骨质疏松性骨折的愈合，其作用机制为：1、提高骨质疏松性骨折大鼠骨密度。2、提高骨痂钙、磷、胶原含量。3、促进骨痂形成。

RESULTS: Four weeks following repair, CT showed that callus formation appeared in coronal skull defects. 3D reconstruction still demonstrated some defects. Hematoxylin and eosin staining displayed defects were fibrous connective tissue, with the presence of chondroid tissues.

结果：修复后4周，冠状位CT显示颅骨缺损区可见骨痂形成，三维重建仍显示有缺损；标本苏木精-伊红染色显示缺损为纤维结缔组织，并有软骨样组织形成，Mallory三色染色标本呈淡蓝色。

Results (1) Primary callus came into being 3 days after operation. Mesenchymal cells from peripheral tissues around the primary callus were differentiated into chondrocytes 1 week later. Endochondral ossification was going on then. Bridging callus was formed in the fracture sites 4 weeks after operation.

结果 (1)伤后3 d开始形成原始骨痂。1周时肉芽组织中的间质细胞开始分化为软骨细胞，软骨形成后再进行软骨内化骨。4周时形成连接骨折端的桥接骨痂。

The implants was embedded in the osteotylus at 16 weeks after operation in the cytoskeleton compound group,while parts of the middle segment of implants in the simple scaffold group was not covered by bone tissues. No porosis was found in the blank control group.

术后16周细胞支架复合组骨痂已能环包植入物，单纯支架组植入物中段仍有部分未被骨组织覆盖，空白对照组没有成型骨痂形成。

The main goal of this technique was direct primary bone healing with no visible callous formation.

这种技术的主要目标是没有明显骨痂形成的直接一期骨折愈合

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。
