METHODS: Serum levels of TNFα in 56 patients (male 18, female 38, aged 1760 years) with ROU were determined by doubleantibody sandwich ELISA, and 8 of them underwent pathological examination. Twentyfive healthy individuals served as controls. RESULTS: Of the 8 cases undergoing pathological examination, 7 showed the inflammatory infiltration of lymphocytes, plasma cells and mononuclear macrophages, and the other 1 showed hyperplasia. The mean serum TNFα level in ROU patients (51.4±6.6)μg/L was significantly higher than that in the controls(8.8±1.2)μg/L (P<0.01) and the serum TNFα level of patients with moderate (n=28, P<0.05) and severe (n=14, P<0.01) ROU was significantly higher than that of patients with mild ROU (n=14, P<0.01). CONCLUSION: The serum TNFα level in ROU patients is significantly increased, which indicates that TNFα may play a role in the pathogenesis of ROU. 【Keywords】 recurrence, oral ulcer; tumor necrosis factor; serum; pathology 【摘要】目的论文集: 研究肿瘤坏死因子(TNFa)在复发性口腔溃疡患者中的论文集变化及临床意义. 方法: 用双抗体夹心ELISA法对复发性口腔溃疡患者56例(男18,女38,年龄17~60岁)血清中TNFa的含量进行了检测,8例进行病理检查,并以25例健康人血清做对照. 结果: 在8例病理切片中7例显示为以淋巴细胞、浆细胞及单核巨噬细胞侵润为主的炎症,1例为增生. 复发性口腔溃疡56例患者血清中TNFa的平均含量(51.4±6.6)μg/L比健康人(8.8±1.2)μg/L明显升高(P<0.01),且中型(n=28, P<0.05)和重型(n=14, P<0.01)TNFa平均含量均明显高于轻型(n=14, P<0.01), 即重型>中型>轻型. 结论: 复发性口腔溃疡患者血清TNFa的含量可明显增高,提示TNFa参与了其病理过程. 【关键词】 复发,口腔溃疡;肿瘤坏死因子;血清;病理学 0引言 复发性口腔溃疡(recurrent oral ulcer)十分常见,其发病率居口腔粘膜病的首位[1],其发病机制至今仍不明确,有人提出口腔粘膜病毒、细菌感染及免疫功能失调是其主要原因. 为了研究复发性口腔溃疡的发病机制与肿瘤坏死因子(TNF) 的关系,对复发性口腔溃疡患者血清TNF进行了检测以探讨其发病机制,并为临床治疗提供相关的科学依据. 1对象和方法 1.1对象 病例选自200401/200506陕西省人民医院口腔科门诊就诊的复发性口腔溃疡患者56(男18,女38)例,年龄17~60(平均30.1)岁. 对照组25例(男9,女14)例,年龄21~55(平均28.2)岁,常规体检正常. 所有研究对象均无心、肝、肺、肾等明显全身器质性病变,无血液及内分泌疾病,无自身免疫性疾病及炎性患者,3 mo内未服用任何激素类药物. 全部患者均按《现代口腔医学》诊断标准分为[1-2]: 轻型口腔溃疡(n=30),即溃疡小而浅,数目少,1~3个,直径1~2 mm,红肿不明显,边缘整齐,有红晕,基底稍凹,平坦;口炎性口腔溃疡(n=26),溃疡表浅平坦,形状不规则,可有小粒至蚕豆大小,直径≥3 mm,可达数10个,相互融合,有黄色渗出物,周围充血明显,范围大,疼痛明显. 根据局部表现,临床分为3型(表1). 表1复发性口腔溃疡临床分型(略)
