摘要
目的:检测高原地区34名聋哑儿童微量元素含量,探讨其与听觉功能的相关性。方法:选择青海地区(海拔2 260m^3 200m)34名聋哑儿童作为研究对象,同时以青海地区同一海拔高度的32名健康儿童做对照。收集受检儿童发样,使用原子吸收分光光度计对样本中17种微量元素的含量进行分析。结果:聋哑儿童发样中硒、锡元素含量高于健康儿童(P<0.05),而锌、铁、钴、锰、锶、钒、铅、镍、铬、钛、钡元素含量则低于健康儿童(P<0.05);聋哑儿童和健康儿童头发中铜、银、镉、铋微量元素含量差异无统计学意义(P值均>0.05)。结论:高原地区聋哑儿童与健康儿童相比,发样中部分微量元素含量存在差异,提示微量元素在不同听觉功能之间可能存在某些内在联系,值得进一步研究。
Objective：To discuss the relation between auditory function and hair trace elements in deaf-mute children at high altitude.Methods：34 deaf-mute children from Qinghai area（altitude of 2 260m^3 200m） were recruited in this study,and 34 healthy children from a same altitude served as the controls.Their hair samples were collected and examined the level of 17 trace elements using atomic absorption spectrophotometer.Results：WLevel of selenium and tin elements were higher in deaf children＇s hair samples than those of healthy children（P0.05）,and level of zinc,iron,cobalt,manganese,strontium,vanadium,lead,nickel,chromium,titanium and barium was lower than healthy children（P0.05）.There was no a significant difference in level of copper,silver,cadmium and bismuth between deaf and healthy children（P0.05）.Conclusions：There is difference in level of trace elements of hair between deaf children and healthy children at high altitude;this result suggests that trace elements could associate with difference of auditory function in children.And the future study will be needed.
