轻型复发性阿弗他溃疡患者铜锌血清含量的临床研究


  [摘要] 目的 比较轻型复发性阿弗他溃疡患者与健康人体内铜离子(Cu2+)和锌离子(Zn2+)的血清含量,探讨其与复发性阿弗他溃疡的关系。 方法 选取2015年3月~2016年12月在解放军白求恩国际和平医院(以下简称“我院”)口腔科确诊的97名轻型复发性阿弗他溃疡(MiRAU)患者和同期来我院体检的102名无MiRAU的健康人为研究对象。分别抽取溃疡发病期的患者(A组)和健康人(B组)5 mL空腹静脉血,再采用色度法检测受试者体内Cu2+和Zn2+的血清浓度。 结果 A、B两组受试者体内Cu2+的血清浓度分别为(16.77±3.89)μmol/L和(17.62±3.05)μmol/L,组间差异无统计学意义(P > 0.05);A组受试者血清中的Zn2+浓度[(14.39±1.86)μmol/L]显著低于B组[(16.18±2.46)μmol/L](P < 0.05)。 结论 锌离子血清含量的降低可能与复发性阿弗他溃疡存在着某种关联性。

  [Abstract] Objective To compare the serum content of iron and Copper Zinc in patients with minor recurrent aphthous ulcer (MiRAU) and healthy individuals, and then to analyze that whether there is a possible relationship between them and recurrent aphthous ulcer. Methods Ninty-seven patients with minor recurrent aphthous ulcer (MiRAU) confirmed in Department of Stomatology of Bethune International Peace Hospital (hereinafter referred to as "our hospital") from March 2015 to December 2016 and 102 healthy persons without MiRAU in our hospital were eolled. The patients with MiRAU (group A) and healthy persons (group B) were extracted 5 mL fasting venous blood respectively, and then the chromaticity method was used to detect the serum concentration of Copper and Zinc irons in subjects. Results The serum content of Copper iron in those subjects of group A and group B were (16.77±3.89) μmol/L and (17.62±3.05) μmol/L, and there was no significant difference between the two groups (P > 0.05). The serum content of Zinc iron in those subjects of group A [(14.39±1.86)μmol/L] was significantly lower than that of group B [(16.18±2.46) μmol/L](P < 0.05). Conclusion The decrease of serum content of Zinc iron may be associated with recurrent aphthous ulcer.

  復发性阿弗他溃疡(recurrent aphthous ulcer,RAU)是一种常见的病因不明的口腔黏膜炎症性疾病,以周期性发作和烧灼性疼痛为其典型的临床特点,发病率高达20%[1-3]。最近有研究报道[4-7],RAU患者血清超氧化物歧化酶(superoxide dismutase,SOD)的含量显著低于无RAU的健康人。SOD是一种能够有效清除超氧阴离子自由基的抗氧化酶,常作为机体抗氧化损伤能力的代表,人体内主要含有铜锌超氧化物歧化酶(CuZnSOD)和锰超氧化物歧化酶(MnSOD)[8]。已有研究证明,癌症、糖尿病、帕金森等疾病不仅与机体的氧化应激状态有关,也与铜、锌等微量元素的血清含量相关[9-12]。因此,本研究通过比较健康人群和RAU患者血清铜离子和锌离子浓度,探讨其与RAU的发病机制是否存在着相关性,为预防和治疗RAU提供理论依据。
