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) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

objective to evaluate early signs of avascular necrosis of femoral head in adult by ct and to guide clinical treatment.methods the cases with suspicious diagnose of anfh were scaned in the both hip joints by x ray and ct to find the early signs of anfh with ct.results early signs of anfh using ct showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.the cases in stage ⅰwere given decompression, while the pationtsresul in stageⅱand stageⅲ were given decompression and ostetransplant.conclusion ct results show that the sign of the high osteodensity and low osteodensity and cyst change can disply early anfh.

摘 要］目的：探讨成人股骨头缺血性坏死的早期ct征象并指导临床治疗。方法：对临床疑诊anfh的全部病例均行x线平片及ct检查，分析anfh的早期ct征象。结果：早期anfh的ct表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的"星状征"，骨小梁境界清楚、锐利，属ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属ⅱ期；并有5个股骨头在ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属ⅲ期。治疗结果：ⅰ期行钻孔髓内减压术，ⅱ、ⅲ期行钻孔减压植骨术。

METHODS: The rib trabeculae were resected and broken, trypsinizated and washed completely by PBS. Bone surface and non-adhesive floating cells in cleaning fluid were observed with inverted microscope. Rib trabeculae was washed by DMEM culture medium once, and cultured in culture bottle. The culture liquid was replaced by new one once a week. The osteoblast was moved from the sclerite a week later. The cells were fused monolayer and could be subcultured 4 to 6 weeks later.

切下人肋骨骨小梁剪碎，胰酶消化后以PBS彻底冲洗直至于倒置显微镜下观察骨片表面及清洗液中无粘着及漂浮的细胞，以DMEM完全培养液清洗骨小梁1次，移入培养瓶内培养，每周更换培养液1次，1周后可见成骨细胞自骨片移出，4~6周细胞融合成单层可作传代培养。

LRP5 is expressed in the osteoblasts lining the endosteal and trabecular bone surfaces, but not in osteoclasts.

LRP5在骨膜内及骨小梁表面的成骨细胞表面表达，而不在破骨细胞中表达。

The results show that, for the first with no headwall, when there is no crosswind, it has small front face areas, so the aerodynamic resistance is the least. Since the second and the third have headwall, the front face areas are large, so they have bigger aerodynamic resistance. Under the condition of crosswind, as the third design option has the highest side beam, the area of positive pressure at the upwind is bigger, and the area of negative pressure is smaller when the bigger eddy area appears, so the side forces become larger. The first has the least side forces; the overturning moment of the first is the least.

研究结果表明：在无横风情况下，方案一中没有端墙，迎风面积较小，受到的气动阻力最小，方案二和三中平车有端墙，迎风面积较大，受到的气动阻力也较大；有横风情况下，方案三中平车侧梁较高，车体迎风面正压区较大，而背风侧产生较大的涡流区，在此区域内压力较小，故其横向力较大，方案一中平车侧梁没有加高，受到的横向力最小；方案一中平车倾覆力矩最小，稳定性最好。

With the pose of aquaporin and the detection of ocular different tissue specificity aquaporin, some researchers believe the expression of AQP1 in trabecular meshwork cells maybe the major factor to GIG, some also suggest that periocular or physical

近年来随着水通道蛋白概念的提出和眼内不同组织特异性水通道蛋白(aquaporin，AQPs)的检出，有学者认为，小梁细胞AQP1的表达可能为皮质类固醇激素引起眼压升高机制的研究带来新的突破，也有学者推测，眼局部或全身使用皮质类固醇激素可能使小梁细胞出现AQP1的异常表达和结构改变，致使房水转导功能下降，眼压升高。

The properties of blast loading are that it is highly impulsive, exhibiting high-pressures but lasting for a very short duration. The propagation process of shock wave produced in steel-concrete composite beams subjected to blast loading is very short. And there is only small deformation for the beam during the time of the propagation process of wave.

由于爆炸荷载作用时间短、超压峰值大等特点，当爆炸荷载作用于钢－混凝土组合梁上时，将在梁内产生冲击波，冲击波在钢－混凝土组合梁内的传播过程极短，并且在冲击波的传播过程中梁的变形很小，因此，可将冲击波在梁内的传播过程进行独立分析。

In an attempt to evaluate the safety and efficacy of Healon in trabeculectomy, 20 eyes with Healon and 20 eyes without Healon injection after trabeculectomy are compared. Trabeculectomy using Healon will not induce transient rise of intraocular pressure. By filling the anterior chamber with Healon, a tamponing effect results which will maintain a deep chamber and reduce complications such as flat anterior chamber, choroidal detachment and striate keratopathy in the early postoperative period. In long-term evaluation there is no difference in pressure control, conjunctival scarring and corneal endothelial cell loss between Healon group and Non-Healon group.关键词 trabeculectomy , flat anterior chamber , choroidal detachment , intraocular pressure

为了评估Healen在小梁切除术中之疗效及安全性，选20位接受小梁切除术者，同时注射Healon於前房为实验对象，另20位接受传统小梁切除术为对照组，发现使用Healon并不会引起一过性眼压上升的现象，Healon注入前房，产生填塞作用，最大的好处是可以维持前房深度，减少术后合并症如前房消失，脉络膜剥离及角膜水肿等，然长期追踪，对於降眼压的幅度，不因使用Healon而可达到低眼压状态，也不会减少结合膜瘢痕化而促进房水引流，然Healon系一无毒，无炎性，无抗原性高黏稠性的物质，不因使用而发生炎性反应，同时有保护角膜内层细胞的功能。
