摘要 目的探讨痛泻要方治疗肝郁脾虚型腹泻型肠易激综合征(D-IBS)患者的作用机制。方法将符合罗马II诊断标准及中医肝郁脾虚证诊断标准的D-IBS患者30例设为治疗组,并选择健康体检者30例作为健康对照组,2组均通过结肠镜取直肠和乙状结肠交界处黏膜,运用Envision法观察肠嗜铬细胞(EC细胞)数量和5-HT含量的变化。结果治疗组治疗后主要症状积分显著降低(P<0.01);治疗组治疗前后5-HT免疫组化染色阳性细胞数及5-HT免疫组化染色强度均显著高于健康对照组,比较差异有高度统计意义(P<0.01);治疗组治疗前后比较,治疗后5-HT免疫组化染色阳性细胞数及5-HT免疫组化染色强度均显著降低,比较差异有高度统计意义(P<0.01)。不论是健康人还是肝郁脾虚型D-IBS患者,直肠和乙状结肠交界处黏膜EC细胞的数量和5-HT的含量呈正相关性;肝郁脾虚型D-IBS患者结肠黏膜EC细胞的数量及其5-HT的含量与患者的病情程度呈正相关性。结论抑制EC细胞的异常增生、调节5-HT的正常分泌,可能是痛泻要方治疗D-IBS的作用机制之一。
