【摘要】 目的：探讨血清铜与复发性口腔溃疡的关系。方法：采用Ｍｅｔａ分析对所收集的国内相关研究文献进行综合的定性和定量分析。结果：复发性口腔溃疡组的血清铜浓度与正常组相比具有显著性差异（Ｐ＜００５），前者比后者平均高００４２～０６２３倍标准差。结论：认为复发性口腔溃疡存在高铜现象。更多还原

【Abstract】 Objective:To study the relation between recurrent aphthous ulcer (RAU) and serum copper. Methods:Synthetic quantitative and qualitative analysis was used to analyze internal document about this relation by means of Metaanalysis.Results:The levels of copper in the serum of patients with RAU were higher than those in the healthy control (P<005). The mean concentrations of copper in the serum of patients with RAU was 0.042～0.623 times of standard deviation higher than those in the healthy control.Conclusion:The authors suggest that patients with recurrent aphthous ulcer have the character of high serum copper.更多还原
