小梁

Methods Thirty-five patients with refractory glaucoma were involved in this prospective and random trial at such high risks as neovascular, uveitis, aphakia, pseudophakic, and young ages. Complex trabeculectomy with single-layer AMT under the scleral flap was performed in 18 eyes and complex trabeculectomy without AMT in 17 eyes.

采用前瞻性随机对照临床试验研究，包括35例（35眼）具有高危因素如新生血管、葡萄膜炎、无晶状体、人工晶状体和发育性的难治性青光眼。18例行复合式小梁切除术联合巩膜瓣下单层AMT，17例行复合式小梁切除术。

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。

On the fracture section, three strain gauges were put above the pins of groups fixed with external fixator. The gauges were recorded when the femurs were loaded vertically. Results (1) The compressive trabeculae and femoral calcar in the femoral neck region are the main load-bearing construction. The contract of the abductor muscle can protect the hip joint. When the model femur was abducted in small degree (10-30°), the stress improved gradually with the abductor angle. But adduction of the model will gradually decrease the stress in that area. When external violence was put on it, the main stress distribution was on the upper femur, which was in the middle and lower part of the femoral neck and between greater trochanter and lesser trochanter.

同时在④⑤两组又应用电阻应变片贴于断端间的三枚斯氏针上方以测定钢针上的应力与应变结果(1)股骨颈处的压力骨小梁和股骨距是重要的承载结构；载荷的传导主要通过压力骨小梁和股骨距由股骨颈区传至股骨干的中下1/3处；外展肌力的收缩对髋关节有一定的保护作用；在小角度外展实验中（10-30°）股骨颈区的应力递增，超过30°时股骨颈区的应力又逐渐减小，但在内收实验中随角度增大股骨颈处应力呈递减趋势；当外界暴力作用时，应力主要集中在股骨上段，即股骨颈中下段和大小转子处及其之间。

Objective: To prevent inadequate drainage of aqueous hunor and the postoperative cicatrice after glaucoma filtering surgery.

摘要目的对青光眼小梁切除滤过术进行改良，以降低青光眼小梁切除滤过术后房水引流不畅及斑痕形成发生率。

The results also indicate that, for murine femora, the scan setup can impact densitometry measurements for both cortical and trabecular bone and morphologic measurements of trabecular bone.

研究结果还表明，对小鼠股骨，扫描设置会影响骨皮质和骨小梁的骨密度测量和骨小梁的形态测量。

Although 25 eyes presented with acute angle closure glaucoma, 6 eyes were insidious onset and asymptomatic. While 27 eyes relieved pupillary block after laser iridotomy or surgical peripheral iridectomy, 4 eyes required vitrectomy or laser photomydriasis to relieve pupillary block. Five eyes (16%) developed chronic angle closure glaucoma due to peripheral anterior synechia. one could be controlled by chronic medical therapy, three required trabeculectomy, the another one even required cyclocryotherapy because poor IOP control after trabeculectomy.

虽然大多数的病例（25只眼）以急性发作为临床表徵，但有6只眼为隐袭性，无任何临床症状。27只眼经雷射虹彩瞳孔术或外科周边虹彩切除术后可以解除瞳孔阻塞，另4只眼无法解除而需作玻璃体切除术或雷射光瞳孔放大术。5只眼(16%)因周边前黏连发生慢性隅角闭锁性青光眼，其中1只眼可以药物控制，3只眼需做小梁切除术，另1只眼做小梁切除术后眼压仍无法控制而接受睫状体冷冻治疗。

Results Osteoclast and osteoblast around trabecula of bones showed proliferation, shi1e fatty tissues in bone marrow decreased and hematopoietic tissue well-regenerated alter the hyperbaric oxygen-treated. Also juvenal osteocyte and collagen fibril were observed in early stage by electron microscope.

结果 多数骨小梁周围可见骨母细胞增生、偶见破骨细胞增生，髓腔内脂肪细胞逐渐减少，造血组织增生；电镜发现骨小梁内早期即出现幼稚骨细胞和胶原原纤维合成。

After one year of low-calcium diet, the BMD of lumbar spine was measured again to ensure the eatablishment of osteoporosis animal model. According to the ladin square design, 20mg bBMP/fibrin sealant, 20mg bBMP and FS were injected into L4、L5、L6 vertebra respectively.

术后3个月时，①采用组织病理学对骨小梁结构进行组织病理学观察；②采用DEXA对腰椎椎体骨质的整体骨密度进行测量；③采用MicroCT对骨小梁微观三维结构进行分析；④采用生物力学实验评估椎体骨质的结构力学强度。

Objective To cultivate human trabecular meshwork cells in vitro and investigate the morphology of cytoskeletal and cell-junction.

目的建立体外培养的人小梁(human trabecular meshwork，HTM)细胞，并观察小梁细胞细胞骨架与细胞连接的形态学特征。

The focus in long bone appears patchy geographic type, the courser of its long axis was coherent with the stress bone trabecula; the focus in vertebral bodies show laterigrade band-like which was distributed in the middle of the vertebral bodies or near the termibal lamella and plumbed with stress bone trabecula of the vertebral bodies.

在长骨灶病呈长斑片地图样，其长轴大体与应力骨小梁走行相一致；在脊柱椎体病灶表现为分布于椎体中央或近终板区的呈横形小片条带状，与椎体应力骨小梁排列垂直。

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）。
