We examined 8 cases after costal cartilage autograft in clinical observation through optics microscope, verified that the framework keeps the nature of costal cartilage and pointed out the importance of prevention of infection. Ear reconstruction can be completed in preschool age because we observed that the reconstructed ear in preschool age could grow with the normal ear in pace (7 cases). With perichondrium costal cartilage autograft could live and grow better.

临床观察8例肋软骨移植后的组织学检查，证实了耳支架成活后保持了肋软骨的生物学特性；强调了预防感染对移植耳支架的转归及治疗效果的重要性；观察到7例学龄前儿童自体肋软骨移植后再造耳廓能随年龄同步按比例生长，表明耳廓再造可在学龄前6岁时完成。

In order to overcome the shortcomings of acellular dermal matrix used as tissue engineering scaffold material, such as bad permeability, low degradation speed, and strong immunogenicity, a new type of collagen scaffold was prepared by applying various chemical, biological and physical comprehensive methods to deal with pigskin. The microstructure of the scaffold was observed under photomicroscope and scanning electron microscopy, and the in vitro degradation time, permeability, tensile-strength, porosity, shrinkage temperature were tested.

为了克服猪脱细胞真皮基质作为组织工程支架材料渗透性差、降解速度过慢、免疫原性较强等缺点，采用多种化学、生物与物理综合方法处理猪皮制备了一种新型天然胶原支架材料，通过光学显微镜、扫描电镜观察以及体外降解时间、透水汽性、拉伸强度、孔隙率、收缩温度等的测定，对其性能进行了研究。

Objective To investigate the nursing intervention in preclusion of post-urethroplasty urinary fis-tula of hypospadia.Methods 70urethroplasty cases were randomly divided into2groups,the urethral stents were douched with0.9%N.S in the cotrol group,and the integrated nursing interventionwas applied in the treatment group,the INI includerays the use of10ml0.9%N.S plus80000units gentamicin for douche,swabbing genitals with nitrofurazone solution and infrared rays exposure of genitals.

目的 采用护理干预手段预防尿道下裂术后尿瘘的发生方法选择尿道下裂带蒂皮瓣正位开口期尿道成形术患者70例随机分 2组：一组是常规用生理盐水冲洗尿道支架管方法；另一组是生理盐水10ml加庆霉素8万U冲洗新尿道支架管，呋喃西林溶液擦拭外阴部以及红外线伤口局部照射的护理干预方法综合护理，观察尿瘘的发生率。

Samples of the composites were taken for histological examination at day 7 and day 14 since OKCs were seeded. Results Multi-layer epithelia without hemidesmosome and basal membrane were observed in composites of PGA showing ill-defined cell layers. OKCs could adhere and proliferate onto collagen membrane forming multi-layer epithelia, with no mature hemidesmosome and basal membrane. That of Alloderm showed normal epithelial structures, with hemidesmosome, basal membrane and cell pseudopod in lamina propria.
