摘　　要：目的检测乌鲁木齐市维吾尔族、哈萨克族、回族等少数民族聋哑儿童体内微量元素含量，探讨其与听觉功能的相关性。方法选择乌鲁木齐市27名聋哑儿童作为研究对象，同时以30名健康儿童做对照。收集受检儿童发样及血样，使用原子吸收分光光度计和电感耦合等离子体发射光谱仪对样本中17种微量元素的含量进行分析。结果聋哑儿童血样中锌、铜、铁、镉、硒、钒、铅等微量元素含量高于健康儿童（P值均〈0．01），而锰、锶、锡和铋元素含量则低于健康儿童（P值均〈0．叭）；聋哑儿童和健康儿童血中钡、铬、银、钴、钛、镍等元素含量差异无统计学意义（P值均〉0．05）。聋哑儿童发样中硒、锡等元素含量高于健康儿童（P值均〈0．05），而锌、铁、钴、锰、锶、钒、铅、镍、铬、钛、钡等元素含量则低于健康儿童（P值均〈0．05）；聋哑儿童和健康儿童毛发中铜、银、镉、铋等元素含量差异无统计学意义（P值均〉0．05）。结论乌鲁木齐市聋哑儿童与健康儿童相比，发样及血样中部分微量元素含量存在差异，提示微量元素在不同人群、不同听觉功能之间可能存在某些内在联系，值得进一步探讨。Objective To explore the relationship between trace elements and auditory function in the deafness children among ethnic minorities in Urumchi. Methods There were 27 deaf-muted children in this study and 30 children with normal hearing as control. Sample of serum and hair from two groups were collected, and we tested 17 kinds of trace elements by using atomic absorption spectropbotometer and inductively coupled plasma emission spectrometer. Results The content of trace elements in serum including Zn, Cu, Fe, Cd, Se, V and Pb from deaf-muted group was more higher than that of control group （P〈0.01）, however, other trace elements including Mn, Sr, Sn and Bi was much lower than that of control group （ P 〈 0.01 ）. Then, the content of those trace elements including Ba, Cr, Ag, Co, Ti and Ni in serum from both of testing and control groups was found no significant difference with each other（ P 〉 0.05 ）. On the other hand, the content of the trace elements including Sn and Se in hairs from deaf-muted group was more higher than that of control group（P 〈0.05）, but the content of the trace elements including Zn, Fe, Co, Mn, Sr, V, Pb, Ni, Cr, Ti and Ba in hairs from deaf-muted group was much lower than that of control group（P 〈0.05）, while the content of the trace element including Cu, Ag, Cd and Bi in hairs from deaf- muted group was found no significant difference between each other（P 〉 0.05）. Conclusions The content of some trace elements in serum and hairs of deaf-muted children is found a significant difference compared with children with normal hearing. This study indicates that some trace elements may relate to auditory function among ethnic minorities in Urumchi.
