The present study has demonstrated the pattern of TNF-α and IL-6 expression, has defined the effect of cellular immunity on BMP-induced osteogenesis at the implant site, and has clarified the immunoregulation by BMP subsequent to bone xenografting, thus opening up a new field of molecular immunology associated with bone xenograft, allowing for the search for a more ideal approach to preventing immune rejection and developing a highly effective xenogenous graft material.

本研究结果揭示了异种骨移植局部TNF-α和IL-6的定位表达及其规律，基本上阐明了移植局部细胞免疫对BMP诱导成骨作用的影响及BMP在异种骨移植局部的免疫调节作用等问题，开辟了异种骨移植分子免疫学新领域，并为选择更理想的移植排斥防治途径和研制高效的异种骨移植材料提供了可靠的实验及理论依据。

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.

在小鼠肌肉内植入同种异体或同系新鲜骨、自消化抗原去除骨、骨基质明胶、脱钙骨基质，术后免疫学、碱性磷酸酶、组织学检查发现：4种同种异体植入物均可引发特异性细胞免疫反应和体液免疫反应，其中以新鲜骨移植引发的免疫反应最为显著；自消化抗原去除骨、骨基质明胶、脱钙骨基质在体外具有抑制淋巴细胞增殖的作用，骨基质明胶对淋巴细胞增殖的抑制作用最显著；同种异体与同系4种植入物在体内成骨活性有显著差异；自消化抗原去除骨、骨基质明胶、脱钙骨基质均有异位诱导成骨活性，其中骨基质明胶骨诱导活性最佳。

Decalcified bone matrix combined with platelet-rich plasma could not promote bone consolidation during distraction osteogenesis compared with blank group.

复合兔自体富血小板血浆的人脱钙骨基质不能有效的加速矿化促进骨愈合。

Test if decalcified bone matrix can promote bone consolidation during distraction osteogenesis.

探讨局部植入脱钙骨基质对牵拉成骨矿化过程的影响。

In the normal distraction rate, decalcified bone matrix could promote bone consolidation during distraction osteogenesis compared with blank group.

在正常的牵拉速度下，脱钙骨基质可以促进牵张成骨矿化过程。

This case demonstrates that distraction osteogenesis can be an effective treatment alternative to regain the vertical bone height in severely resorbed edentulous ridge.

本病例显示牵引骨化术对於垂直齿槽骨严重吸情况是另一种有效的治疗选项。

Pull piece of ossification is two character that offer to cutting bring up the rear to still withhold periosteum, parenchyma and blood paragraph, pull Zhang Qi inflict through securing what go up at its the drawing of specific size or outspread force, make bone paragraph new spirit of the second birth inside clearance is lengthened or widen skeletal, add the surgical skill that bone measures.

梗概： 牵张成骨(D istraction osteogenesis，DO)是对切断后仍保留骨膜、软组织及血供的两个骨段，通过固定于其上的牵张器施以特定大小的牵引或扩张力，使骨段间隙内再生新骨延长或拓宽骨骼，增加骨量的外科技术。

Results All the 18 rabbit models entered the final analysis. X-ray showed that osteotylus was seen in the whole defect area in the experimental group 12 weeks after operation, during which osteogenesis was more obvious than in weeks 4 and 8 and the bridge grafting of defect area was obviously visible.

结果 18只模型兔均进入结果分析。X线结果显示，4周时实验组桡骨缺损区可见明显的骨生成影像，呈云雾状分布，随时间的延长骨量增多，至12周时，植入体已与缺损处断端骨性愈合，皮质骨连续性较好。

From this study, we can conclude that the mandibular condyles go through a process of extracelluar matrix alteration and remodiflcation during distraction osteogenesis.

其中，骸状突软骨细胞外基质的含量和成分出现较明显的改变，并且这些改变是可逆的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
