【摘要】 为了探讨血清锌与复发性口腔溃疡的关系，本文应用Ｍｅｔａ－ａｎａｌｙｓｉｓ法对所收集的国内相关研究文献进行综合的定量分析。结果表明：复发性口腔溃疡组的血清锌浓度比正常组的血清锌浓度平均低０．３５１７倍标准差，９５％置信区间为（－１．１００２～０．３９７２），因此，可以认为缺锌是复发性口腔溃疡的病因之一。更多还原

【Abstract】 In order to study the relation between recurrent aphthous Ulcer and serurm zinc, Synthetic guantitative analysis was carried out to analyze related internal document about the relation by means of Meta-analysis, The result Showed fhat the mean concentrations of,zinc in the serum of patients with RAU was 0.3517 times standard deviation lower than those in the healthy controls,the 95% confidence interval was -1.1002～0.3972.Therefore we think deficient zinc is one of the causes of recurrent aphthous ulcer.更多还原
