To study the application and clinical result of extended trochanteric osteotomy in hip joint revision. Thirteen hips in 13 patients who were treated with extended trochanteric osteotomy in hip joint revision from 2003 to 2007 were followed-up for an average time of 32.3 months.

探讨 粗隆延长截骨在髋关节翻修手术中的实际应用及疗效对2003～2008年13例接受髋关节翻修手术中进行大粗隆延长截骨的患者进行随访，共13髋，平均随访32.3 月。

Results Positive staining for VEGF was distributed mostly in osteoblasts, osteoclasts and newly-born osteocytes. Vascular endothelial cells and bone marrow cells also showed VEGF positive reaction. Hypertrophic chondrocytes in calcifying region of chondroephysis were VEGF positive, but VEGF was absent from chondrocytes in other zones of chondroephysis.

结果 VEGF阳性反应主要见于成骨细胞、破骨细胞及新生骨细胞中，血管内皮细胞及骨髓细胞也呈阳性反应；骺软骨钙化区肥大的软骨细胞为VEGF阳性反应，但其它区域的软骨细胞中无VEGF表达。

Objective:To explore the application of the basic fibroblast growth factor combined partially demineralized allogenic bone in mandibular defects, and to study the effects of bFGF in bone formation as well as the selection of its carrier.

目的：探讨bFGF(basic fibroblast growth factor ，碱性成纤维细胞生长因子)复合部分脱矿冻干辐照异体骨在修复下颌骨缺损中的应用，研究bFGF在骨缺损修复中的成骨作用机制及其适宜载体的选择。

Patients in later series had neither risk factors for osteonecrosis nor osteonecrosis at other extraskeletal sites; instead osteoporosis and significant cardiovascular morbidity/atherosclerosis was found in most of the patients.6,19,21 Other findings suggesting an ischemic etiology in these patients is absent enhancement on MRI of the affected vertebrae,7,15,20 "ischemic bone" noted intraoperatively,14 and vertebral body biopsies demonstrating reactive bone/fibrosis and occasionally osteonecrosis and hyalinized marrow.

以后病例系列中的患者既没有引起骨坏死的因素，在其它地方也没有出现骨坏死，而是骨质疏松症和显著的心血管疾病/动脉粥样硬化发病率[6，19，21]，其他的发现表明，在这些患者受影响的椎体上MRI不会出现增强影[7，15，20]，术中可看到&缺血性的骨块&[14]，椎体活检可看到有活性的骨/纤维化，有时可见骨坏死和玻璃样变[8，11，14，16，17，30，31]。

Objective To study osseointegration of implants in vascularized tubular bone and provide a basis of theory.

目的 探讨种植体在血管化骨中的结合机制，为今后研究种植体在自体骨中的结合提供实验理论依据。

This study will contribute to a better understanding of mechanism of bone remodeling during tooth movement which may set the basis for clinical work. Methods1. Observe the expression of ATF4 protein in periodontal tissues after orthodontictooth movementA titanium-nickel closed-coil spring was applied to the occlusal surface of the rat maxillary first molar (M1) with a hook and the upper incisors with a ligature wire.

但正畸骨改建与骨发育是两种不同的生理过程，ATF4在正畸牙齿移动牙周组织的表达和分布，在机械力的作用下体外培养的人牙周膜细胞中表达变化的情况，以及在牙周膜细胞向成骨样细胞分化的过程中所起的作用，国内外尚未有报道。

METHODS: 5 g CPC was dissolved in 2 mL water, and then 0.1 g Doxorubicin microspheres was incorporated into the powder-phase CPC. The column microsphere bone cement was prepared at a diameter of 0.18 cm and a height of 1.12 cm. While untreated CPC was taken as blank control and Doxorubicin control was also prepared.

将2 mL水加入5 g骨水泥粉中，然后迅速将干燥的0.1 g多柔比星微球加入其中，搅拌均匀成糊状后推入预制磨具中制备成直径0.18 cm，高1.12 cm的柱状载微球骨水泥，两断端平行，打磨光滑平整，同时制备不载多柔比星的空白对照组、多柔比星原药对照组。

Objective To investigate the dose-effect effects of th ree relating bone growth factors, dexamethasone, recombinant human basic fibro blastic growth factor and recombinant human bone morphogenetic protein- 2 (rhBMP-2), on proliferation and differentiation of periosteal cells so as to provide experimental basis for their further application in bone tissue engineer ing.

骨膜细胞是骨修复、重建过程中重要的功能细胞，在一定条件下具备向成骨细胞分化，分泌骨细胞外基质的潜能，因此成为骨组织工程研究中构建细胞-材料复合体非常重要的种子细胞。

Objective To study the use of neuronavigation in combined transpetroal approach, and to provide the observation of the anatomic structure of the facialnerve canal for protecting nerve.

目的 探讨神经导航这一高技术在经岩骨幕上下联合入路中的作用，为经岩骨幕上下联合入路中保护面神经管提供解剖研究。

Of course, since the 1990s, some artists in the Chinese painting field have given prominence to the use of no-born technique in the portrait and landscape paintings. But in Liuming's works, the use of no-born serves for the artistic realm, expressing the desire of retuning to the matrix.

当然，上世纪九十年代以来，中国画领域的一些艺术家突出了没骨的技法在人物画、山水画中的运用，但在刘鸣的作品中，没骨法的运用是为艺术境界服务的，表达的是回归母体欲望。

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。
