摘要
背景:腹痛是一般人群中最常见的肠道症状,肠易激综合征(IBS)患者的腹痛症状更为严重、频繁,然而其发生机制尚不明确。目的:分析IBS患者结肠黏膜中与痛觉和内脏高敏感相关的辣椒素受体VR1、P物质(SP)和肥大细胞(MC)的变化,探讨IBS患者内脏高敏感和腹痛的发生机制。方法:39例IBS患者[腹泻型IBS(IBS-D)21例,便秘型IBS(IBS-C)18例]和18名健康人纳入研究。受检者于结肠镜检查时在回盲部和乙状结肠取活检,行VR1、SP免疫组化染色和MC改良甲苯胺蓝染色。结肠镜检查前采用视觉模拟评分法行疼痛评分。结果:IBS患者乙状结肠VR1、回盲部和乙状结肠SP免疫反应阳性细胞以及回盲部MC数量显著多于正常对照组(P<0.01),IBS-D与IBS-C组间则无明显差异。IBS-D和IBS-C患者的腹痛评分均与VR1呈正相关(r=0.553,P=0.009;r=0.592,P=0.010)。结论:IBS患者结肠黏膜中VR1、SP免疫反应阳性细胞和MC数量显著增多,VR1与腹痛评分呈正相关,三者可能参与了IBS患者内脏高敏感和腹痛的发生机制。
