BACKGROUND: Currently, the materials used in clinical practice to repair cruciate ligament of knee joint contain auto-graft bone- mid 1/3 patella tendon-bone, auto-semitendinous muscle, gracilis muscle and allogenic tissue graft. All of them are limited to a certain degree in clinical application.

For the PUU/BO-g-VER (n-butanol graft VER network)hybrid film, the miscibility between the soft and hard segments in PUU phase was improved byadding the BO-g-VER network into PUU, resulting in remarkable reinforcement effect andgreat improvements of mechanical properties for the films. In the PUU/200-g-VER [Mn: 200,poly graft VER], the 200-g-VER network had considerable compatibility withboth hard segments and soft segments in PUU phase, then good reinforcement effect wasrealized, giving rise to higher tensile strength and elastic module, lower elongation at break ofthe hybrid films.

由于BO-g-VER与PUU硬段具有较好的相容性且促进了PUU软硬段间的微相混合，导致PUU／BO-g-VER hybrid膜的力学性能有较大程度的提高，体现了明显的增强效果。200-g-VER(分子量为200的单官能团聚醚接枝VER)与PUU软硬段均有很好的相容性，因此PUU／200-g-VER hybrid有较好的增强效果，使胶膜的拉伸强度和弹性模量提高，断裂伸长率下降。

In this paper, the enzymatic hydrolysis lignin derivatives were synthesized. Halogenation of EHL was carried out in aqueous solution, and graft copolymerization of EHL was initiated by initiator. The chlorinated and graft copolymerized EHL were respectively applied to the chlorinated polyethylene rubber and styrene-butadiene rubber, and the properties of rubber were investigated.

本文采用水溶液法和引发剂引发法分别对酶解木质素进行了卤化和接枝共聚反应研究，合成酶解木质素的改性衍生物，将其分别应用于氯化聚乙烯橡胶和丁苯橡胶，并探讨橡胶各项性能的变化。

Once proper placement is confirmed, additional granulated bone graft tissue is packed around the cage and this is surrounded by a layer of Surgicel Fibrillar hemostat to prevent migration of graft tissue into the epidural space.

当确定cage的位置安放好以后，将额外的颗粒状骨移植物填塞于cage周围，并以纤维止血膜包裹以防移植骨移动到硬膜外腔。

All iliac hone graft fused well and a great deal of bony callus was found the vertebral body surface. Lucency area was in seen surrounding the hone graft, titanium and AC-AFF on the X-ray films, and there wan new bone formation in the interface of internal union and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary aim of implants by CT scan. And port of the new hone transited the parietal reticulation and connected with normal ones at titanium and AC-AFF.

髂骨植骨组融合情况良好，融合界面上有较多的骨痂生成。X线摄片见植骨块、钛网、AC-AFF中空区域模糊且有骨组织生长，内植物周围无透光带存在，植骨界面上有骨桥形成；CT扫描在钛网及AC-AFF组可见内植物腔内形成的新骨通过其四壁的网眼结构与周围骨质相接，说明所有标本均达到骨性融合，但其中以AC-AFF组形成的新骨数量为多，且较为成熟。

INTERVENTIONS: Right femoral stem was exposed under aseptic operation for the establishment of osseous defect model with a 10 mm defect. HA mass artificial osseous graft + HA-coated titanium plate fixation were used in study group; HA mass artificial osseous graft + common titanium plate or stainless steel plate were used in control group.

干预：动物在无菌操作下显露右股骨干，造成一长约10 mm的骨缺损模型，实验组用HA块状人工骨植骨+HA涂层钛板固定，对照组用或不用HA块状人工骨植骨+普通钛板或不锈钢骨板固定，分别于术后2，4，6，8，12，16周取出标本进行大体形态观察和组织学观察。
