BACKGROUND: Bone morphogenic protein 2 is one of the most important growth factors in the healing of bone fracture. The main function is to promote the undifferentiated mesenchymal cells and bone cells to recruitment and differentiate. It is the promoter of bone formation. The BMP-2 gene is an ideal gene that can be used to repair the bone.

背景：骨形成蛋白2是骨基质中最重要骨生长因子，主要生物学作用是促进未分化的间充质细胞和骨系细胞的募集和分化，是骨生成的启动因子，可以作为骨修复基因治疗的理想目的基因。

The microstructure of the sintered bone was observed by scanning electron microscope and mercury porosimeter. Results showed that the sintered bone possess the three dimensional space structure composed of macropores and micropores. The diameter of macropore was 50-400 μm and the diameter of micropore was about 1 μm. Results suggest the sintered bone of β-TCP remains the porous structure of natural cancellous bone which is benefit to growing of new bone.

［Objective］To compare the clinical results of different bone graft in the posterior route spinal fusion of adolescent idiopathic scoliosis.［Method］A retrospective study was made in 71 case of adolescent idiopathic scoliosis,who were operated on with posterior instrumentation of screw-rod fixation system from 2000 to 2005.All of the patients were divided into three groups,autologous bone graft in 21 cases,allogous bone graft in 23 cases, autologous bone mixed allogous bone graft in 27 cases. The fusion rate, the Cobb's angle loss rate of incidence and pseudoarthrosis were compared among the three groups at 3,9,15,36 months follow-up.

［目的］通过不同植骨在青少年特发性脊柱侧凸后路矫形植骨融合术中的应用比较，探讨其临床应用效果［方法］回顾性分析2000年～2005年行后路钉-棒系统矫形手术的71例青少年特发性脊柱侧凸患者，其中自体骨移植21例，同异体骨移植23例，自体骨混合同种异体骨移植27例，比较随访第3、9、15、36 月的融合率、Cobb's角丢失率及假关节发生率。

We show using in vitro and in vivo models that active TGF-beta1 released during bone resorption coordinates bone formation by inducing migration of bone marrow stromal cells, also known as bone mesenchymal stem cells, to the bone resorptive sites and that this process is mediated through a SMAD signaling pathway.

我们利用体外和体内模型，发现在骨吸收过程中释放的有活性的TGF-β1通过诱导骨髓基质细胞的迁移至骨重吸收位置来调节骨形成，这一过程通过SMAD信号途径调节。

Obvious cartilage and island-distributed immature bone formation in implants of the experiment side were observed at 2 weeks after operation, and massive mature bone observed at 4 weeks. Newly formed bone had fused and formed mature lamellar bone and trabecularism. No bone formation was observed in the control side of the mice.

实验侧术后2周出现大量软骨组织和呈岛状散在分布的骨组织，术后4周可见大量成骨组织，新生骨相互融合生长并形成较为成熟的板层骨和骨小梁结构；对照侧未见骨组织形成。

Transiliac bone biopsy showed highly increased bone mass (+63% versus age- and sex-matched controls), a decrease in bone remodeling without evidence of active osteoblasts, and a severe decrease in the dynamic parameters of bone formation (mineralizing surfaces,-90% and bone formation rate,-93% versus age- and sex-matched controls).

经髂骨的活检示骨量显著增加（与年龄和性别匹配的对照者相比增加了63％），骨重建降低且没有发现破骨细胞活化的证据（与年龄和性别匹配的对照者相比：矿化面-90%，骨形成率-90%）。

Results There was moderate or strong negative correlation among the indexes of the degeneration of intervertebral disc including the relative area of vascular bud, the ratio of the uncalcified and the calcified layer, the quantitation of collagen type Ⅱand the indexes of osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the density of femoral bone and vertebral body bone, the max stress and straining of bone.

结果 骨质疏松相关指标骨皮质厚度指数、骨小梁相对面积、股骨密度、椎体骨密度与椎间盘退变指标终板血管芽相对面积、非钙化/钙化层比值、Ⅱ型胶原定量之间存在中度到强度的负相关，而与Ⅹ型胶原表达存在中度到强度的正相关，其中椎体骨密度与软骨终板的Ⅹ型胶原相关性最强。

Treatment of spinal tuberculosis1methods between february 1998 and august 2000 , 12 patients with spinal tuberculosis were operated with anterior vertebrectomy , bone grafting and plating1 evaluation including bone fusionrate , correction of deformity and status of spinal lesion was carried out1results in an average of ten months ,spinal tuberculosis was completely cured and solid bone fusion had taken place in all 12 patients1 the time for bone fusion averaged 518 months and the average angle of correction of kyphosis was 16°1conclusions anterior plating following vertebrectomy and bone grafting offers a complete removal of lesion and decompression of the spinal canal as well as reconstruction of spinal stability1 early rehabilitation and an increased curative rate can be expected through this procedure1

目的 探讨经脊柱前路结核病灶清除的同时植骨内固定的可行性和必要性，以及对脊柱结核的治疗效果。方法1998 年2月~2000 年8 月采用脊柱前路病椎切除加植骨，并采用orion或z-plate 钢板进行椎体固定。共治疗12 例脊柱结核，观察植骨融合及矫正畸形情况和结核病灶愈合情况。结果经平均10 个月的随访，12 例患者脊柱结核均治愈，植骨与受骨区全部骨性融合，融合时间平均为518 个月，后凸矫正角度平均16°。全组病例切口均一期愈合。无手术并发症。结论本方法可经脊柱前路作较彻底的病灶清除，并较好地进行脊柱矫形和椎管减压，完成脊柱稳定性重建，有利于患者早期离床活动和脊柱结核治愈率的提高。

Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.
