Histological findings in the experimental side included active proliferation of osteoblast in exterior periosteum, fibrous connection, cartilage and newly formed bone trabeculae between fragments of the fracture at the end of the 2nd week; 组织学:实验侧术后2周骨外膜成骨细胞增生活跃,骨折断端间纤维连接,并出现了软骨组织和新生骨小梁;
Results: There were two rings system in external nose: ① Alar cartilaginous fibrous ring consisted of the medial crus, lateral crus, septum, accessory cartilage as well as fibrous tissues between anterior nasal spine and accessory cartilage; 结果:外鼻下端存在两个环状解剖结构。①由鼻翼软骨内、外脚及穹窿部,鼻中隔,小翼软骨和连结小翼软骨与前鼻棘的纤维组织组成的鼻翼软骨纤维环;
In the control groups, the fibrous cartilage repair was observed first, then the fibrous tissues and bone repairs were found. 而对照组12周时为纤维软骨修复,后期为纤维组织和板层骨修复。
The fibrous cartilage zones had a transition structure at18 weeks. 术后18周可见具有过渡结构的纤维软骨带。
In the one-day group, only the fibrous layer and the cartilage layer were involved, while in the one-month and three-month group the fibrous layer, the cartilage layer and the bone-cartilage interface were all involved. 固定1天组,变化涉及纤维层及软骨层,固定1个月和3个月组,改建涉及纤维层、软骨层和骨-软骨交界层。3个月组较1个月组变化轻。
Results β-TCP was invaded and encased gradually by fibrous tissue with no cartilage, bone and necrotic tissue formation. 结果随着时间推移,β&TCP逐渐被纤维组织分割包围,但是无软骨、骨和坏死组织形成。
Gene expression of TGF-β 1 in bone callus: In the second week after fracture, there were a small amount of fibrous bone callus and comparatively much cartilage bone callus, and TGF-β 1 was hypso-expressed in cartilage cells inside the cartilage islet; 骨痂中转化生长因子β1的基因表达:骨折后第2周,骨折端有少量纤维骨痂,软骨骨痂较多,转化生长因子β1在软骨小岛内的软骨细胞中高表达。
Results In the reactive repairing state of osteoarthrosis, the apoptosis cells mainly located in the superficial fibrous layer of articular cartilage. 结果关节盘损伤后软骨产生明显应激性修复增殖反应时,凋亡细胞主要集中于关节表面的纤维层中;
RESULTS The chondrocytes/ PDLLA graft group repaired the rabbit ear defects after 18 weeks of the transplantation and the defects were repaired with cartilage tissue, but the two control groups were repaired with fibrous cartilage or fibrous tissue. 结果术后18周,软骨细胞/PDLLA复合物移植组软骨缺损区为软骨组织修复,新生软骨与正常软骨问连接好,单纯PDLLA对照组和空白对照组为纤维软骨或纤维组织修复。
Granulation and fibrous tissue, callus of cartilage between ends of bone and materials and bone proliferation were observed by X-rays and pathological sections, and carried on pathological rating of soft tissue and growth grade of callus of bone ends. 通过X线片及病理切片观察骨折断端与材料间肉芽组织、纤维组织、软骨骨痂和新骨增生情况,给予行软组织病理评级,并给予骨断端骨痂生长情况分级。
However, cell source of fibrous cartilage is still a problem to be solved. 然而成纤维软骨种子细胞的来源依然是亟待解决的问题。
Ilizarov distraction technique in minimally invasive moderate stretch stress, less fibrous cartilage after more than before, suggesting that we are in clinical use in the regulation of speed can slow down after the first, the method of combining speed. 2. 结论:1.在Ilizarov微创牵张技术适度牵拉应力下,纤维软骨先多后少,提示我们在临床中在调节速度方面可以采用先快后慢,快慢结合的方法。
In control group, the defect was still remained and covered by a thin layer of fibrous tissue whenever in 4 and 12 weeks, indicating the poor self-repair ability of cartilage defects. 而空白对照组无论在4周还是12周缺损处凹陷明显,表面只覆盖有一薄层纤维组织,提示软骨的自我修复能力很差。
Control group, the surface smooth and continuous, condylar cartilage can be divided into fibrous layer, proliferative layer, hypertrophic and calcified cartilage layer and layer of cells in each layer arranged in neat, clear boundaries. 实验结果:1.对照组髁突软骨表面光滑连续,可分为纤维层、增殖层、肥大层和钙化软骨层,各层细胞排列整齐,界限清晰。
Results: 4 weeks after surgery, the defects were filled with fibrous or immature repair tissue in ACP/ PLLA/ bFGF and PLLA/ bFGF groups. No obvious cartilage tissue was observed in both groups. 结果:在术后4周时,ACP/PLLA/bFGF组和PLLA/bFGF组缺损内均充满一些不成熟的或纤维样的修复组织,但没有明显的软骨组织形成。
Membrane area and region of fibrous tissue within the bone like tissue generation, fracture broken end of fibrous callus formation, visible piece of cartilage tissue, fibrous tissue proliferation and a large number of trabecular bone formation. 膜区及机化区的纤维组织内有骨样组织生成,骨折断端处有纤维性骨痂形成,可见成片的软骨组织,纤维组织增生和大量骨小梁形成。
