摘要 目的:通过观察 TFF1在人消化性溃疡及阿司匹林诱导的兔胃溃疡中的表达,探讨 TFF1在胃黏膜保护中的作用.方法:采用免疫组化方法测定正常及消化性溃疡患者、正常及阿司匹林诱导的兔胃溃疡模型中胃黏膜 TFF1的表达,通过图像分析软件分析其阳性信号平均光密度值了解其表达情况.结果:(1)消化性溃疡患者胃黏膜中 TFF1的表达高于正常胃黏膜(P<0.01);其中,多发/复合性溃疡表达高于单发消化性溃疡(P<0.05).(2)阿司匹林诱导的兔胃溃疡周围黏膜TFF1表达高于正常兔胃黏膜(P<0.05).结论:TFF1于在人消化性溃疡及药物诱导的兔胃溃疡中的表达较正常升高,提示其在胃黏膜保护及上皮重建机制中具有重要的作用.
