Objective To explore the changes of metatarsal arrangement and their association with forefoot adduction after modified Mckay procedure.

目的：探讨先天性马蹄内翻足患儿的跖骨排列改变以及其与改良Mckav术后前足内收的关系。

The results show that: the input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar; the stress distribution of the femur under external violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.

分析结果表明：股骨颈处的压力骨小梁和股骨距是重要的承载结构，临床医学治疗股骨颈骨折时，内固定物的放置应循压力骨小梁方向并尽量紧贴股骨距钻入；暴力作用时股骨上端的应力分布特点从生物力学的角度说明了老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

1 Cementless: The two main types of cementless stems of use in femoral reconstruction are broadly divided into shorter proximal fit stems, such as may be used in primary total hip arthroplasty, and longer stems designed for revision purposes to fit distally within the diaphysis.

非骨水泥型：在股骨重建中使用的两种主要类型的非骨水泥型假体干，划分为较短的近端匹配干，如可能在初次全髋转换中使用的，和为翻修目的设计的较长的干，可以在骨干内远端匹配。

To address more specifically the mechanisms involved in cortical bone healing, we created drill-hole defects in the cortex of mouse femur, a lesion that triggers intramembranous repair, and compared the roles of bone sialoprotein and osteopontin, two proteins of the extracellular matrix, in the repair process.

为了更具体的了解皮质骨修复过程的机制，我们在小鼠股骨上制造了一个钻孔缺损，这一损伤能引发股骨的膜内修复，并比较细胞外基质中的两种蛋白骨涎蛋白和骨桥蛋白在这一修复过程中的作用。

The pseudopodial movement could be inhibited by calcitonin (100 μg*L－1). Lacuna formation could be found in cocultured specimens. There were fibrils on the walls of lacunae. The MGCs demonstrated positive reaction with Gomori stain. Conclusion: The results demonstrated that MGCs had the same morphological features and the bone resorption ability as the osteoclasts.

结果：倒置相差显微镜下可见多核巨细胞胞核较多（20个以上），胞浆周边不规则，有伪足样突起；胞浆内可见较多大小不等的空泡；降钙素（100 μg*L－1）可抑制多核巨细胞的伪足样运动；多核巨细胞与灭活的骨片共同培养时可见骨吸收陷窝形成，扫描电镜下可见吸收陷窝底面有原纤维；Gomori染色时可见多核巨细胞的酸性磷酸酶呈阳性。

These results indicated that HA and PmmA are both good bone graft substitutes for mastoid obliteration causing no structural or functional damage to inner ear and inducing no rejection or inflammatory reaction. PmmA, in particular, can be prepared as the occasion requires and can be solidified in a short time, making itself endurable and mouldable.

内耳连续切片，HE染色，光镜观察：实验耳耳蜗结构，形态正常，毛细胞排列整齐，〓泡内壁对HA和PmmA未呈现任何炎性细胞和巨噬细胞等，表明人造骨对内耳结构和功能无损害，不引起排斥或炎症反应，相容性好，是良好的骨组织代替材料，尤其是骨水泥可临时配制，能在短时间内象水泥一样凝固，具有一定的抗压性及成形性，是一种良好的乳突重建材料。

Methods 6 sets of data were measured on the 166 radiograms of normal ankle joint. There were length of lateral malleolus (L1), length of tibiofibular overlapping (L2), adds of L1 and L2, three angles of difference point of medial malleolus.

测量166例正常成人踝穴位X线片上外踝长度(L1)、下胫腓重叠影的长度(L2)以及两者之和(L3)和内踝远端内下骨皮质表面不同的3点在胫骨远端骨质范围内投影的夹角，分析其相互间特点。

The number of screw holes per plate length is maximized, without compromising plate strength. This allows an increased number

在保持接骨板强度的前提下，最大化接骨板钉孔的数目，在有限切口范围内提供更多的固定点。

Cases recovered completely, and some various complications occurred in 14 cases. Conclusion Harrington rod is an effective internal fixation device for the reduction of fracture and dislocation of vertebra with its longitudinal stress. This device corresponds to the biomechanics of the spinal column. But during the operation, complications should be avoided or diminished by performing strict aseptic technique, bending of the rod to a proper physiological curvature which corresponds to injured spine, doing posterior bone grafting and using corset support after operation.

结论哈氏棒是一种符合生物力学的内固定器材，具有较强的纵向撑开力，能使骨折脱位得到很好复位，但亦具有一些缺点，如术中能做到置钩前预制好骨孔，并将哈氏棒预弯成与伤段脊柱相应的生理弧度，加用钢丝固定双棒，行后路植骨融合，术后使用支架保护，严格无菌操作等，可大大降低并发症的发生。

Methods: Volume scans of temporal bone was performed in 25 patients (50 ears) with 3D-FIESTA sequence. Post-procession with multiplanar reformation, maximum intensity projection and virtual endoscape were operated to evaluate the ability of 3D-FIESTA sequence to show anatomic structures and lesions in inner ear and internal auditory canal.

用GE signa 3.0T超导型磁共振对25例共50耳应用3D-FIESTA序列做颞骨三维容积扫描，采用多平面重组、最大强度投影及仿真内窥镜行后处理，观察3D-FIESTA序列对内耳及内听道内各解剖结构的显示。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
