Abstract´╝Ü 目的: 探讨炎症性肠病患者肠黏膜CD14的表达及与该病的关系.方法: 收集活动性溃疡性结肠炎(ulcerative colitis, UC)患者25例及克罗恩病(Crohn's disease, CD)患者15例;20例对照来自于非炎症性肠病患者手术切除的正常结肠组织(肠镜及肠黏膜病理组织学检查结果均正常).炎症性肠病的临床诊断均依据于常规影像学、内镜学及组织学标准.采用免疫组织化学方法检测肠黏膜组织中CD14表达量.结果: 肠黏膜固有层单个核细胞表达CD14.UC患者CD14阳性细胞百分数高于CD患者,但二者差异无统计学意义(P>0.05);UC患者较正常对照有显著性差异(t=4.404, P<0.01),CD患者较正常对照亦见显著性差异(t=3.324,P<0.01).CD14的表达与疾病活动度(diseaseactivity index, DAI)相关, UC组轻、中、重度比较有显著性差异(F=56.709, P<0.01);CD组轻、中、重度比较亦有显著性差异(F=12.880, P<0.01).结论: CD14参与了炎症性肠病的发病过程, 其表达强度反映了该病的程度.
