为了探讨儿童急性开放性跟腱损伤的修复方法,回顾总结了24例儿童急性开放性跟腱损伤的资料。本组均行一期清创术,根据跟腱及皮肤损伤情况不同而采用合适的方法修复跟腱,皮肤缺损则使用适宜皮瓣修复。结果显示,本组随访13个月~42个月,平均29个月,本组无跟腱再断裂;1例发生皮瓣远端部分坏死及2例伤口发生感染,均经换药后愈合良好;余伤口愈合良好。皮瓣6个月后均恢复部分感觉。因此,儿童急性开放性跟腱损伤应根据跟腱及皮肤软组织损伤情况采取合适的处理方法,彻底清创并恢复跟腱长度及保持跟腱张力非常重要。

Ag^＋ -doped ZnS nanocrystals surface-capped with thiourea （expressed as ZnS： Ag/thiourea） were synthesized through sol-gel method with thiourea as a surface modifier and characterized by X-ray diffraction（XRD）, transmission electron microscope（TEM）, X-ray fluorescence spectrum（XRF）, infrared spectrum （IR）, UV-Vis absorption spectrum（ UV-Vis）, and photoluminescence spectrum（PL）. The results show that Ag^＋ ions are doped in ZnS nanocrystals, and the sulfur atoms in thiourea molecules coordinate with metal ions on the surface of the nanocrystals. The spherical ZnS： Ag/thiourea nanocrystals with an average diameter of 5 nm have good fluorescent characteristics, and therefore have great potential for use in molecular assembly and novel luminescence materials.
