Methods: The transect fracture were simulated in 12 fresh cadaver phalange specimens.

在12例新鲜尸体手指标本上，模拟横断骨折，分别采用弧形交叉髓内钉与普通交叉克氏针进行固定，以MTS试验机模拟持续被动运动进行屈伸疲劳，检测固定效果。

Failure test and displacement evaluation were used to study the biomechanics of reconstruction of ACL by hamstring tendon knot implant fixation in 13, simple tendon knots, and hamstring tendon knot with bone bolt press fit technique in 5 porcine knees.

本研究采用绳肌腱结嵌压固定法和髌腱骨界面螺钉固定法重建交叉韧带，从生物力学的角度来探讨不同材料与固定方法对固定强度的影响。1 材料与方法1.1 实验材料深低温冷冻保存的猪膝关节 35个模拟交叉韧带重建，常温下解冻，取其胫骨、股骨和髌腱骨复合材料和绳肌腱。

A virus strain was isolated from the arthrosis of broiler chickens.The virus was shown to have spherical particles with isometric symmetry,no envelope,double deck capsids,with outer capsid of 75nm,inner one of 50nm in diameter by electron microscopy.The virus was not sensitive to aether,acid and heat.The virus could multiply on the chick embryo fibroblastcell,and could cause syncytial pathologic change with the appearance of cytoplasm inclusion bodies.The challenged chickens of one-day old by nasal,oral,intramuscular and pulvillus injection displayed obvious clinical symptom of severe arthritis and accompanied with pathological changes of malabsorption and necrosis.Meanwhile,four avian reovirus isolates CL,S1133,YH and YB were examined in the cross-neutralization test.

从临床患病鸡关节病料中分离到一株病毒，在电镜下观察到病毒粒子无囊膜，有双层衣壳，外衣壳直径约75nm，内核约50nm；分离病毒株对酸、热有较强的抵抗力，对乙醚不敏感；病毒感染鸡胚成纤维细胞上能产生以融合细胞为特征的CPE；爪垫接种1日龄雏鸡表现出明显的病毒性关节炎临床症状，并伴有吸收障碍型和坏死型的病理变化；血清中和交叉试验表明，该病毒分离株与国内的2株番鸭源呼肠孤病毒分离株和国外S1133呈不同程度的交叉反应。

The synthesis and design of the conventional filters; Further more, waveguide multiplexer and the general Chebshev filters with transmission zeros were introduced. Multipath coupling Equivalent Circuit are constructed and the relative phase shifts of multiple paths are observed to produce the known responses of the cascaded triplet and quadruplet sections.

给出了传统滤波器的基本理论和设计方法，继而介绍了波导多工器和广义切比雪夫滤波器的综合理论；分析了相位关系和交叉耦合的电路模型；给出了在腔体滤波器中实现交叉耦合的方法。

OBJECTIVE: To observe the histologic changes of ACL following reefing treatment, so as to investigate the optimal location to exercise RF reefing on.

目的：观察前交叉韧带不同部位进行射频紧缩后的组织学变化，以确定前交叉韧带射频紧缩的最佳部位。

BACKGROUND: The radiofrequency reefing has been widely used in clinic, and anterior cruciate ligament laxity is one of its indications. However, the histologic changes of ACL following reefing treatment remain unknown.

背景：射频紧缩已广泛用于临床，前交叉韧带松弛为射频紧缩治疗的适应证，但紧缩治疗后前交叉韧带的组织学变化尚不清楚。
