Result］the operation time was 1～3 h,the operative bleeding quantity were 150～400 ml,all incisions were obtained primary healing.twelve cases were followed up from 6 months to 8 years.the average extremity functional score according to the system of isols（international society of limb salvage）:upper extremity was 22.3 and the lower was 25.3 the average bone healing time of returned deactivation bone graft and bone allograft healing with the osteotomy plane was 3 months,original tumor recurrence in local was 1,the recurrence rate was 7.69%,no malignant change and metabasis was found.

结果］手术时间1～3 h，术中出血量150～400 ml，术后切口一期愈合。12例患者获6个月～8年随访。按isols评分标准评价肢体功能恢复情况：上肢平均22.3分，下肢平均25.3分。灭活回植骨、异体骨与截骨端平均3个月愈合，局部复发1例，复发率7.69%。无恶性变及全身转移。

LeFortⅠosteotomy is an important surgical method in midfacial obsolete fractures management. The cephalometric radiography and model surgery should be performed depending on the principles of orthognathic surgery before LeFort Ⅰosteotomy. The other fractures of facial bones besides maxilla should be managed surgically in the same operation.

LeFort Ⅰ型截骨术是治疗陈旧性面中部骨折的重要手术方法，术前应依照正颌外科原则进行X线头影测量和模型外科准备，术中应同期进行上颌骨骨折之外的其他面骨骨折的复位固定。

Ore-binding factor alpha 1 plays an essential role in bone formation and osteoblast differentiation and serves as a master gene regulating osteoblast-specific gene expression. The gene is expressed in cells of the osteoblast lineage only, and when expressed in non-skeletal cells, the cells assume many of the characteristics of an osteoblast.

bfal在骨形成和成骨细胞分化过程中起着重要的作用，是调控成骨细胞特异性基因表达的主控基因，该基因只在骨形成相关细胞中表达，如果使其在非成骨细胞中表达，该细胞将出现成骨细胞的特征。

The tumor was excised and was found to be composed of bony trabeculae in a fibrotic stroma with many osteoclasts, a finding consistent with osteitis fibrosa.

切除肿块后发现肿块的成分为骨小梁和纤维化机制，机制中有许多破骨细胞，此发现与纤维性骨炎相符。

Objective: The purpose of this study was to investigate the effect of TNF-α on osteoclast differentiation in primary murine bone marrow cell culture with and without RANKL.

目的：在诱导破骨细胞分化的体外骨髓细胞培养系统中，研究破骨细胞分化因子存在和不存在的情况下，肿瘤坏死因子α对破骨细胞分化的影响。

During the process of osteophyte formation mesenchymal cells covering the periosteal bone surface proliferate and differentiate into chondroblasts and osteoblasts, which build up cartilage and bone matrix.

在骨赘形成过程中，覆盖骨膜骨的间充质细胞增生、分化为软骨母细胞和成骨细胞，后两者构建了软骨和骨基质。

Objective:Osteoporosis is syndrome shown on the bone absorptive rate is higher than formative rate during the metabolism of their bones. As the result, the progression of calcium deficiency and the degeneration of bone tissue are the characters in this period. Clinical manifestations appear on these elder persons, which are osteosclerosis and increasing the possibility of fracture.

目的： 骨质疏松症(Osteoporosis，简称OP)是指在骨代谢过程中，骨吸收大于骨形成，出现以低骨量和骨组织的显微结构的退行性变为其特征，临床表现为骨脆性和骨折易感性增加的一种代谢性疾病。

Objective:Postmenopausal Osteoporosis is syndrome shown on women caused by the functional descent on both ovaries and the level of estrogen. During the metabolism of their bones, the bone absorptive rate is higher than formative rate. As the result, the progression of calcium deficiency and the degeneration of bone tissue are the characters in this period. Clinical manifestations appear on these elder women, which are osteosclerosis and increasing the possibility of fracture.

目的： 绝经后骨质疏松症(Postmenopausal Osteoporosis，PMO)是指绝经后妇女由于卵巢功能衰退，雌激素水平下降，从而在骨代谢过程中，骨吸收大于骨形成，出现以低骨量和骨组织的显微结构的退行性变为其特征，临床表现为骨脆性和骨折易感性增加的一种代谢性疾病。

Objective: Menopausal osteoporosis is syndrome shown on women caused by thefunctional descent on both ovaries and the level of estrogen. During the metabolism oftheir bones, the bone absorptive rate is higher than formative rate. As the result, theprogression of calcium deficiency and the degeneration of bone tissue are thecharacters in this period. Clinical manifestations appear on these elder women, whichare osteosclerosis and increasing the possibility of fracture.

目的： 围绝经期骨质疏松症是指围绝经期女性由于卵巢功能衰退，雌激素水平下降，从而在骨代谢过程中，骨吸收大于骨形成，出现以低骨量和骨组织的显微结构退行性变为特征，临床表现为骨脆性和骨折易感性增加的一种代谢性疾病。

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。
