小梁

The external fixator was a good, economical, effective and simple method in the treatment of femoral neck fracture. The three pins used in fixation of femoral neck fracture are important. The placement of the pins should be in accordance with the compressive trabeculae and clingy to the femoral calcar.

3动力髋螺钉虽然在固定强度上优于其它各组，但却由于手术创伤大、对股骨头残存血供破坏较大等缺点而限制了其应用；自行设计的外固定支架为一种简单、有效、实用、经济的固定方法，有一定的推广价值；穿针方向应循压力骨小梁方向尽量贴近股骨距低角度倒三角形钻入才符合生物力学原理。

Thirty cadaveric femurs were randomly allocated into five groups, each with 6 femurs. An osteotomy was made (Pauwels angle 70°) in the middle of the femoral neck. Then each group was fixed using one of these methods:①Dynamic Hip Screw ;②Three 4mm Steinn Pins that placed in accordance with the compressive trabeculae and clingy to the femoral calcar ;③One compressive screw;④Low angle fixation of external fixator;⑤High angle fixation of external fixator.

3取经防腐处理的人尸体股骨30具，随机分成5组，每组6具，在股骨颈中部按Pauwels角70度锯断，每组分别以以下方法固定：①动力髋螺钉固定；②三枚4mm斯氏针按本文第一、第二部分分析出的股骨的主应力方向（按压力骨小梁方向紧贴股骨距低角度倒三角形钻入）固定；③一枚加压螺纹钉固定；④自行设计的外固定支架低角度倒三角形固定；⑤外固定支架按大角度固定。

Aim :To xplore the changes of cancellous bone connectivity of osteoporosis and develop a computer-aided measurement method.

本研究旨在观察骨质疏松症小梁骨连接性参数的改变，并介绍一种计算机辅助测量方法。

Signal intensity on T2-weighted depends on the amount and degree of bony trabeculae, cellularity and collagen.

在T2WI所呈现的信号特点依赖于骨小梁、细胞成份及胶原纤维的多少。

Results: 1. A collarless press fit canine femoral stem of CFRPSF composite (elastic modulus was 40 GPa, containing carbon fiber 30%) using HA (50%) and PSF (50%) composite for surface coating was made. Directions of carbon fiber in the stem were similar to the arrangement of trabeculae of proximal femur.

实验结果：1。用弹性模量为40GPa，碳纤维含量为30％的聚砜复合材料，制造出纤维排列方向模拟股骨上段骨小梁走行，表面涂层为羟基磷灰石50％/聚砜50％混合物的压配型狗人工髋关节股骨柄假体。2。

Methods:168 patients with 202 eyes performed compound trabeculectomy were retrospected.

回顾1996年8月至1999年8月行复合式小梁切除术168例、202眼的病历。

Abstract］Objective To investigate the effect of sodium hyaluronate on corneal endothelial cells in trabeculectomy.

目的 探讨小梁切除术中应用透明质酸钠对角膜内皮细胞数量和形态的影响。

Moreover, the active form of beta-catenin accumulated selectively in the trabecular endosteum in "Wnt 3a-stimulated" or "irradiation-stressed," but not in "steady-state" marrows.

此外，在Wnt 3a-激活"或"照射-胁迫状态下，而不是骨髓稳态状态时活化的β-连环蛋白选择性的积聚于小梁骨内膜。

A trabecular microfracture of the lateral epicondyle, most likely caused by an impaction force, can be seen.

股骨外上髁可见骨小梁微骨折，这很可能是由压缩暴力所致。

While the treatment group rats bone epiphysis was thicker, the trabecular pattern was similar to the normal group.

治疗组与模型组相比骺板增厚，骨小梁排列及走行基本达到正常组水平，立体网状结构得到一定程度修复。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
