Objective: By investigate the difference of nitric oxide contents in adult and fetal rabbit wound healing, it was expected to probe the potential reasons of fetal scarless wound healing.

导读：摘要目的：分析胚胎无瘢痕愈合的潜在原因，研究NO在成人型和胚胎型愈合过程中的差别。

DATA EXTRACTION: Forty-eight articles on experimental study relating to embryonic scarless healing were collected in all. Sixteen experiments accorded with the inclusive criterion and 32 were excluded.

资料提炼：共收集到48篇与胚胎无瘢痕愈合相关的实验研究，16个实验符合纳入标准，排除32篇。

DATA SYNTHESIS: Sixteen experiments discussed the relationship between the fetus and scarless healing on terms of growth environment, inflammation reaction to trauma and regulation of fibroblast in organism, extracellular matrix and nany cellular factors.

资料综合：16个实验从胎儿的生长环境、对创伤的炎症反应、肌体内纤维母细胞及细胞外基质、以及众多细胞因子的调节等等方面寻找其与无瘢痕愈合的关系。

STUDY SELECTION: The documents were examined at first to exclude the study on non-healing mechanism. Full texts were found in the surplus documents. The inclusive criterion was the foundational experiment on the mechanism of scarless healing.

资料选择：对资料进行初审，筛除非愈合机制的研究，对剩余的文献查找全文，以相关无瘢痕愈合机制基础实验作为纳入标准。
