Abstract

目的 探讨加味人参乌梅汤对SCFAs-GPR41/43信号通路的影响,揭示该方对腹泻大鼠的止泻效应机制。 方法 从32只SPF级幼龄SD大鼠中随机抽取8只为空白组,其余大鼠以30%番泻叶灌胃配合劳倦力竭和饮食失衡持续造模14d制备腹泻大鼠模型,成模大鼠随机分为模型组、西药组和中药组,各组分别给予相应药物干预7d后取材检测。靶向代谢组学测定大鼠血清短链脂肪酸(short-chain fatty acids,SCFAs)含量;ELISA法检测血清白细胞介素(interleukin,IL)1β、10、17及肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)、转化生长因子-β(transforming growth factor-β,TGF-β)含量;RT-PCR、Western blot法分别检测结肠组织闭合蛋白(Occludin)、紧密连接蛋白1(Claudin-1)、闭锁连接蛋白1(Zonula occludens-1,ZO-1)、G蛋白偶联受体(G-protein coupled receptor,GPR)41、43基因和蛋白相对表达量。 结果 SCFAs含量:与空白组比较,模型组血清丙酸、丁酸、戊酸含量显著降低(P
