DM soft tissue less and stiffer than healthy group, it's the major factor to cause high forefoot pressure, the ankle dorsiflexion is the 2nd reason, the calcaneus tendon geometry shape was not different between two group.

左脚压力较右脚大之原因为惯用侧，神经病变受测者因本体感觉较差与关节活动度受限使接触时间增加，进而提高压力时间积分，糖尿病足的二、三和四跖骨大於正常足，糖尿病跖骨软组织厚度少於正常足且较硬，此为影响前足受压力影响的主因，背屈则次之，而跟腱的几何尺寸两者并无差异。

Results:(1) FSN can inhibit secondary joints swelling and multi-arthritis evidently, improve the whole condition of rats; at the same time, it can also lighten the synovial inflammation and hyperplasia of lesion joints distinctly, and prevent the joint cartilage and bone from destruction; the collective efficiency of FSN is better than TWP.(2) FSN can raise AA rats low LTT of spleen to normal nearly, remedy the disorder of Th / Ts and Thl / Th2 cells balance in peripheral blood, restrain exorbitant TNF- a ? IL-1 produced by PM O , thereof exert anti-inflammatory and immunoregulation effect.(3) Inside the lesion joints, FSN can depress abnormal hyper-expression of TNF- a mRNA and NF-kB in synovial tissues, as well as advance the expression of Caspase-3 (a proteolytic enzyme of apoptosis), reduce synovial immflamination and proliferation.(4) FSN can lower the expression of VEGF in synovial tissue,reduce neogenetic veins, so inhibit the growth of pannus tissue and the damage of cartilage and bone by that.(5) The above effect of FSN are in proportion to its dosage.Conclusions: FSN has inhibitory effects on symptom and condition of experimental RA, which is better than TWP as a whole.

结果：(1)FSN有明显的抗炎作用，可显著抑制AA大鼠足跖肿胀与多关节炎，改善大鼠的全身情况，同时明显减轻病变关节滑膜炎症与增生，防止关节软骨及骨质的破坏，其综合作用优于TWP；(2)FSN还能使AA大鼠低下的脾LTT恢复至接近正常，纠正外周血中T细胞亚群Th／Ts及Th1／Th2平衡紊乱，抑制大鼠PHφ过高的TNF-α、IL-1分泌，而发挥抗炎和免疫调节作用；(3)在病变关节局部，FSN能显著抑制AA大鼠滑膜细胞异常增高的TNF-αmRNA的表达，降低滑膜组织中NF-kB表达，并增加凋亡蛋白酶Caspase-3表达，从而抑制滑膜的炎症与增殖；(4)FSN还可下调滑膜组织中VEGF表达，减少血管新生，由此抑制血管翳的形成及其对软骨和软骨下骨的侵蚀；(5)FSN的上述作用皆呈现一定的量效依赖关系，高剂量组作用优于低剂量组。

The main work of this paper: Firstly, Basing on the summarization and analysis of the walking mechanism, Parallel drive five-bar mechanism is applied for walking mechanism. And then the characteristic of the trail and positive kinematics as well as reverse kinematics are discussed. Secondly, the model of walking mechanism is established according to Parallel drive five-bar mechanism, and then a figure planning is designed for the foot-end trail. The characteristics of the parallel drive are emphasized to research in this paragraph by the method of insert value. At last, the simulation is performed in the ADAMS to compare the real result to the theoretical value. Thirdly, a sealed structure of a Quadruped Walking Robot is designed and established. The whole control system, including motor, sensor and control circuit, is sealed in the robot. Walking is derived in the way of the shaft driving and the dynamic torque sensor is used to the surrounding conditions of the robot's foot-end to be the foundation of the robot's control. At last, the applying principle of the dynamic torque sensor is researched in detail basing on the traditional sensor of the walking robot. Moreover, the principle is divided into several sorts to discuss. Finally, simulation and verification of the monitor principle are come through in the Mechanism of the Pro/Engineer.
