The patients were treated with routine manipulation(group A,30 cases) and PMWL(group B,30 cases) respectively.The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.

分为2组，分别采用常规治疗和杠杆扳法治疗，每组30例，在治疗1个疗程(10次)后利用UCLA进行功能评分，比较两种治疗方法在疼痛、功能、主动前屈活动、前屈肌力及患者满意度方面的差异。

MAIN OUTCOME MEASURES: Stress images and peak stress of pedicle screws under lumbar axial compression, anteflexion, extension, lateral bending and rotation.

主要观察指标：椎弓根螺钉在轴向压缩、前屈、后伸、侧屈和旋转等各种生理载荷下的应力云图和峰值。

RESULTS:In vertebral pulp extirpation group, the stress was proved to be the highest at superior edge, posterior middle part, lower edge and anterior middle part of small joints under anteflexion, backward extension, compression, lateroflexion and revolving states, moreover, small joint stress in artificial lumbar intervertebral disk was higher than that in normal intervertebral disk, but obviously lower than that in vertebral pulp extirpation group;however, the small joint of the middle part of artificial lumbar intervertebral disk bore the highest stress under revolving states.

结果：髓核摘除组小关节的上边缘部、后中部、下边缘部和前中部在前屈、后伸、压缩、侧屈、旋转状态应力最大，人工腰椎间盘组的小关节的应力比正常椎间盘高，但明显小于髓核摘除组，但正中部在旋转状态下，人工腰椎间盘小关节的中心部位承受的应力最大。

This paper reviews whether forward movement of the posterior corneal surface occurred, changes in posterior corneal power and curvature, changes in posterior corneal astigmatism and tilt, changes in posterior corneal asphericity and BFS after the surgery.

本文综述了准分子激光屈光性手术后角膜后表面是否发生前移改变、角膜后表面屈光力、曲率、散光度、轴度、非球面特性以及最适球面等是否发生改变的研究进展。

Although the clinical experience and the results of animal experiments indicate that the adminis- tration of atracurium at recommended doese is unlikely to result in laudanosine concentrations capable of producing seizure activity, Hennis et al found that at a plasma concentration below that causing convulsions, laudanosine "awaken"dogs lightly anesthetized with halothane.

临床病人应用常用剂量阿屈宁后，血浆Laudanosine选低于使动物发生惊厥所需的浓度，数百万例应用阿屈宁的病人中也未见有因代谢生成之Laudanosine而发生惊厥体征或脑电征象者。可以认为，阿屈宁的临床应用是不会因Laudanosine的生成而引起惊厥的。

ROM of the following construct fixation with Codman plates, Window plates with grafts and 1 mm shortened grafts were measured respectively, and the graft height were determined for each specimens by physical measurement of discectomy site.

将12例小牛颈椎标本随机分成两组，用生物力学测定仪测定正常颈椎C(下标 4/5)节段在前屈、后伸、左右侧屈、左右旋转时的三维运动范围，然后切除C(下标 4/5)椎间盘，制成损伤模型，测定植骨加钢板，植骨块缩短1mm加钢板固定后C(下标 4/5)节段的ROM，植骨块的长度根据测量椎间隙的高度而定。

METHODS: The stability of intact specimens in flexion, extension, lateral bending and torsion was examined. A fracture model was created using dropping technique. The fracture model was instrumented with short-segment pedicular screw fixation (4-screw construct) or the intermediate screws structure (6-screw construct).

测量完整标本前屈-后伸、侧屈及旋转的稳定性后，通过重物撞击技术制造伤椎骨折模型，然后对每个标本行传统短节段椎弓根螺钉固定（4枚螺钉固定）及增加骨折椎椎弓根螺钉固定（6螺钉固定）。

Every indicatrion has statistics difference after six mouthstreatment of Two rattan mixture which include body function, activity index number of pathogenetic condition, total swelling arthrosis, total self-assessment, rachialgia, rachiodynia rhachitis, activity of thoracic skeleton, schober, distance between fingers and ground, left flection of antisternum, right flection of antisternum, antisternum hypsokinesis, distance between head and wall, ESR, C reactive protein: every indicatrion has statistics difference after the treatment of Sulfasalazine except the indicatrion of distance between head and wall.

二藤合剂组治疗6个月后其各项观察指标(包括躯体功能、病情活动指数、肿胀关节总数、总体自我评价、脊柱痛、脊柱炎症，胸廓活动度、Schober、指地距、脊椎左屈、脊椎右屈、脊椎后仰、枕墙距、血沉、C反应蛋白)与治疗前相比，均有统计学差异(P＜0.05)；柳氮磺吡啶组除枕墙距外，其余观察指标亦均有统计学差异(P＜0.05)。

And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.

另外，以聚乳酸/几丁聚醣作为基材并添加不同比例的非晶型磷酸钙，经过水洗固化后可得白色片状沉淀物，於室温下静置48小时后，复合材之体积呈现膨胀且具有可塑形之特性，以热重分析仪与流变仪分析样品之含水率与屈伏应力，结果显示不同ACP含量对复合材含水率与屈伏应力具有消长变化，而PLA/Chitosan/ACP之可塑程度与其所吸收之水份多寡有关，推测可能机制为ACP磷酸钙盐解离后之金属离子与几丁聚醣之胺基透过螯合作用或静电吸引之交互作用，形成具吸水性之离子团簇分散於疏水性之聚乳酸基材中。
