Methods Autologous BMMSC of New Zealand rabbits were acquired and induced into chondrogenic differentiation by adding transforming growth factor-β1 (TGF-β1), dexamethasane and ascorbic acid in vitro. Then the chondrocytes were implanted onto novel polymeric scaffolds made by Poly (dl-lactide-co-glycolide) embedding with chitosan nonwoven cloth. The tissue engineering cartilaginous grafts composed of chondrogenetic BMMSC/scaffolds were finally transplanted into the defects of ear cartilage in rabbits of the experimental group.

Objective To discuss the clinical effect of repairing soft tissue defects in cnemis,ankle and foot with reversed sural posterior fasciocutaneous island flaps. Methods 14 cases of soft tissue defects in cnemis,ankles and feet were repaired with reversed sural posterior fasciocutaneous island flaps. The sizes of the flap ranged from 7cm×5cm to 15cm×10cm.

2The distribution of HIF-1 a and COX-2 was unequal;.(3)These findings indicate that HIF-1a and COX-2 may be two important factors in pulpal lesions and there is a significantly hypoxia condiction in inflamed pulp .(4)The increase of HIF-1 a is a possible mechanism for hypoxia preconditioning .(5)Our results suggested that pulpal fibroblasts as well as macrophages might be involved in the pathogenesis of irreversible pulpitis.

和COX一2的表达均有不同程度的变化，在牙髓炎病程中可能发挥着重要的生理和病理作用，③在牙髓炎进程中和牙髓自身修复过程中存在着缺氧环境和缺氧耐受机制，④牙髓成纤维细胞有可能与单核巨噬细胞一同参与牙髓炎的病理进程，且具有修复和免疫功能。

Objective to evaluate the functional recovery of acute spinal cord injuried rats treated with exogenous wnt-3a signal protein administration and to explore its mechanism.methods moderate spinal cord contusion injury was made in 40 adult sprague dawley rats at t10.twenty rats served as contusion controls(group 1).twenty rats were treated with wnt-3a for three days after injury (group 2).the functional recovery of the rats was observed through basso,beattie,bresnahan open field locomotor score.rats were killed at 14 or 28 days after injury,then spinal cords were removed for histopathological examinations,and the expression of the bromodeoxyuridine plus neural cell markers was stained with immunohistochemical method.results rats of two groups receiving a contusive injury recovered substantial function within 1 week.by 28 days,rats in groups 2 scored 7.0 points better on the bbb scores than rats in group 1 group 2=16.94,after 28 days vs.

目的 研究外源性wnt-3a信号蛋白对脊髓损伤的修复作用，并探讨其作用机制。方法取40只成年雌性sd大鼠在t10节段制备适度脊髓挫伤模型。随机从中取20只为损伤对照组(group 1)，另外20只为损伤治疗组(group 2)。脊髓损伤3天后用wnt-3a蛋白治疗。这些大鼠的功能恢复通过basso、beattie、bresnahan开放视野运动评分来观察。这些大鼠分批在损伤后14天或28天被处死，取出损伤节段脊髓用来组织病理学检查，同时用5-溴脱氧尿嘧啶核苷和神经细胞标记物进行免疫组化染色。结果两组大鼠在伤后一周运动功能有明显的恢复。不过，到损伤后28天，我们观察发现，损伤治疗组中的大鼠bbb评分比损伤对照组中的评分高出7.0分左右(group 2∶16.94±1.18，group 1∶9.89±1.29；p.05)，光镜和电镜检查发现wnt-3a蛋白对髓鞘形成和轴突再生有一定的修复效果。

With only a onemonth interim dressing, two-thirds remained coronally impermeable, i.e., no penetration could be observed along the restoration margin.

换句话说，沿着修复体边缘没有渗漏。这些研究的结果显示，由于可能的冠方临时修复体的微渗漏，暂封材料最长不要超过4周

This includes (1) fixation or replacement of the radial head,(2) fixation of the coronoid fragment,(3) repair of the lateral collateral ligament complex, and (4) repair of the medial collateral ligament and/or application of a hinged external fixator for patients who demonstrate residual instability.

该方法包括：桡骨头复位或置换，冠状突骨块的复位，侧副韧带的修复以及修复内侧副韧带或对些肘关节不稳定的患者应用外固定架。

Method］Neonatal cyanotic blue rabbits were used. Dermal tissue directly isolated through mechanical method and cells through enzymatic digestion were obtained.

［目的］探讨真皮多能干细胞在软骨缺损修复中的可行性，为扩大软骨缺损修复中种子细胞的选择提供实验依据。

It is well known that retinal pigment epithelial cells are predominant proliferative cells in PVR which is an excessively wound healing response occurring after RPE cell wounding. The activated RPE cells migrate from their normal, sessile state to vitreous and onto both surfaces of the retina, in which they begin to dedifferentiate, migrate, proliferate, change phenotype and secrete ECM.

既往研究证明视网膜色素上皮(retinal pigmentepithelial，RPE)细胞是参与PVR的主要细胞，PVR是视网膜脱离后RPE细胞损伤的一种自我修复过程，是一种过度的眼内创伤修复反应；RPE细胞在正常位置上处于静止状态，而在某些病理条件下，如视网膜裂孔形成和视网膜脱离后，RPE细胞脱离原位，开始去分化、移行、增生、发生表型转化并分泌胶原等ECM，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。
