| 目的 探讨鄂温克族骨性关节炎患者血浆中21种微量元素的含量水平。方法 采用0.3mL HNO3+0.3mL H2O2混合消解液消化血浆样品，用电感耦合等离子体质谱（ICP-MS)测定血浆中Li、Mg、Al、Ca、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、As、Se、 Sr、Mo、Cd、Ba、Tl、Pb等21种微量元素，用t检验方法统计分析。结果 病例组和对照组血浆中6种元素（Ti、V、Ni、As、Mo、 T1)低于方法的定量检出限；其他15种元素均检出，其中，病例组血浆中4种元素Al,Ca,Cr,Cd的含量低于对照组；11种元素 Li, Mg, Mn, Fe, Co, Cu, Zn, Se, Sr, Ba, Pb的含量高于对照组，且Co和Pb含量在两组间比较具有统计学意义（P < 0. 05 )。结论 鄂温克族骨性关节炎患者血浆中微量元素普遍髙于正常对照水平，且Co与Pb元素水平与骨性关节炎患者发病存在潜在的相关性。 |

| Objective To investigate the distribution of 21 types of plasma trace element in Ewenki patients with osteoarthritis. Methods The plasma samples were digested in the mixture of 0. 3 ml of HNO3 and 0. 3 ml of H2O2. Plasma Li, Mg, Al, Ca, Ti, V, Cr, Mn, Fe, Co, Ni，Cu, Zn, As, Se, Sr, Mo, Cd, Ba，Tl, and Pb were detected using inductively coupled plasma mass spectrometry (ICP-MS). Data were analyzed using t test. Results The concentrations of the six elements (Ti, V, Ni, As, Mo, and Tl) were lower than the quantitative detection limit of the method. The levels of Al, Ca, Cr, and Cd in the osteoarthritis patients was lower than those in the control group, while the concentrations of Li, Mg, Mn, Fe, Co, Cu, Zn, Se, Sr, Ba, and Pb were higher than those in the control group. In addition，the levels of Co and Pb were significant different between the two groups (P <0, 05). Conclusion The content of trace elements in Ewenki patients with osteoarthritis is higher than that in control group. The levels of Co and Pb is potentially associated with osteoarthritis. |
