摘要 目的研究老年人十二指肠溃疡(DU)患者的胃黏膜屏障功能。方法检测60岁以上幽门螺杆菌(HP)阳性DU患者的胃黏膜磷脂、氨基己糖、血清表皮生长因子(EGF)、一氧化氮(NO)含量及胃黏膜组织病理学变化,并与60岁以下HP阳性DU患者和HP阴性、胃黏膜病理大致正常的青年人作对照观察。结果老年组胃黏膜磷脂(84.03±26.06)、氨基己糖(36.51±12.97)及血清EGF(0.41±.0.16)含量较中青年(109.16±32.69,53.68±15.47,0.59±0.19)和正常对照组(133.18±32.12,65.61±20.90,0.73±0.18)明显降低;血清NO含量(3.10±0.94)较对照组(2.21±0.77)明显增高(P<0.001),但和中青年比较差异无显著性(P>0.05)。老年DU胃黏膜慢性炎症程度显著加重(P<0.01)。结论老年人DU存在有胃黏膜屏障功能减退,胃黏膜的退行性变可能是胃黏膜防御功能降低的组织病理学基础。
