文题释义:

软骨组织工程:是将软骨种子种植于可生物降解、组织相容性好的生物材料上,形成复合物,然后再把该复合物植入软骨缺损处,在生物材料自行降解的过程中,种植的细胞形成新的软骨来填充缺损。
自体软骨移植:Donald等采用异体软骨移植的方式对不同类型软骨缺损进行治疗,并与自体软骨缺损的临床效果进行比较。通过比较发现,两种不同的软骨移植方式在排斥率和感染率方面经比较差异均无显著性意义。但较之自体软骨移植,异体软骨移植存在明显吸收现象。学者们还认为,如果在临床治疗中利用良好的方法对异体软骨予以妥善保存,则可显著降低其移植后的吸收现象,达到与自体软骨移植相同的治疗效果。

异体软骨移植:郑信民等通过实验发现,利用具有良好活力的同种异体软骨进行软骨修复治疗可以获得理想的临床效果。在将同种异体软骨植入人体之后,可以维持20年左右的存活时间且很少会出现明显的吸收现象,临床修复效果十分理想。

Abstract:

BACKGROUND: Tissue-engineered bone can be obtained by the combination of chondrocytes and polyglycolic acid scaffold.
OBJECTIVE: To investigate the effect of allogeneic chondrocytes/polyglycolic acid scaffold compound in the repair of thyroid cartilage defects in rabbits.
METHODS: Twenty New Zealand adult rabbits were randomly divided into experimental group with implantation of allogeneic chondrocytes/polyglycolic acid scaffold compound and control group with implantation of polyglycolic acid scaffold. Gross and histological observations were done at 4 and 8 weeks after implantation.  
RESULTS AND CONCLUSION: (1) Gross observation results: 4 weeks after surgery, cartilage defects in the experimental group were repaired certainly, and no necrosis appeared in the repair area; in the control group, the defects were filled with muscle and connective tissues. At 8 weeks after implantation, cartilage defects in the experimental group were further repaired, with unclear repair boundaries, and in the control group, cartilage defects were no repaired and showed a notable boundary with the surrounding normal cartilage tissues. (2) Immunohistochemical staining results: the expression of type II collagen in the experimental group was higher than that in the control group (P < 0.05) at 4 and 8 weeks after implantation. These findings indicate that the allogeneic chondrocytes/polyglycolic acid scaffold compound can promote the repair of thyroid cartilage defects in rabbits.
