OBJECTIVE: From the point of view of material science, the methods of tissue repair and defect reconstruct were discussed, including mesenchymal stem cells (MSCs), growth factors, gene therapy and tissue engineered tissue. METHODS: The advances in tissue engineering technologies were introduced based on the recent literature. RESULTS: Tissue engineering should solve the design and preparation of molecular scaffold, tissue vascularization and dynamic culture of cell on the scaffolds in vitro. CONCLUSION: Biomaterials play an important role in the tissue engineering. They can be used as the matrices of MSCs, the delivery carrier of growth factor, the culture scaffold of cell in bioreactors and delivery carrier of gene encoding growth factors.
目的 总结术后早期炎性肠梗阻的临床特点及诊治经验。方法 回顾性分析我院2004年1月至2010年12月期间收治的22例腹部手术后早期炎性肠梗阻患者的临床资料。结果 全组均行保守治疗，均治愈出院。肠梗阻解除时间平均6.5d。2例出院后再次出现慢性肠梗阻，经保守治疗好转。结论 术后早期炎性肠梗阻在腹腔严重感染性疾病术后多见，治疗以保守治疗为主，同时应动态观察腹部症状、体征变化，严防误诊、误治。
The Influence of microwave and hot water immersion hyperthermia on the lymphedematous skin of lower extremity on 12 patients was studied by using immunohistochemical and lymphoscintigraphic methods. We assumed that the subsidence of inflammatory changes in the lymphedematous limb and/or local absorption of tissue fluid protein following local microwave heating, but not the augmented lymph How seemed to be responsible for the reduction of edema.
目的:探讨糖尿病合并结核病的临床特征、诊断和治疗。方法:分析总结了49例老年糖尿病合并结核病患者的临床资料,同时与老年单纯肺结核患者进行了对比。结果:两组临床症状无显著性差异,糖尿病合并肺结核组干酪渗出性病灶要多于单纯肺结核组(Plt;0.05),中、下叶病灶要多于单纯肺结核组(Plt;0.01)。两组疗效无显著性差异(Pgt;0.05)。 结论: 糖尿病合并结核病应引起高度重视,正确诊断和及时处理是提高疗效重要手段。
早产儿视网膜病变（ROP）是儿童盲的重要致盲原因之一，随着ROP防治指南的颁布以及ROP筛查工作的开展，我国ROP发病率和致盲率有所下降。正确认识和理解ROP分类、筛查标准和治疗指南；建立完善的ROP筛查体系，提高筛查水平；加强ROP临床和基础研究，将有助于进一步降低我国ROP发病率和致盲率
