NMR联用HILIC-UPLC-MS/MS测定TNBS诱导的结肠炎大鼠尿液和血浆代谢物变化 [PDF]
目的基于非靶标和靶标代谢组学技术,探讨三硝基苯磺酸(TNBS)诱导的结肠炎模型大鼠尿液以及血浆中内源性代谢物的变化。方法16只雄性SD大鼠随机分成对照组和模型组,每组8只,对模型组大鼠给予TNBS灌肠以建立实验性大鼠结肠炎模型。利用核磁共振氢谱(1H NMR)检测两组大鼠尿液代谢物,同时联用HILIC模式超高效液相色谱串联三重四级杆质谱(HILIC-UPLC-MS/MS)测定以上大鼠尿液以及血浆中氨基酸水平,并通过多元变量统计方法对代谢组学数据进行分析。结果同对照组相比,1H ...

针灸作为传统医学的重要组成部分,近年来在缺血性卒中治疗中的机制受到广泛关注。本文对针灸通过干预脑-肠轴治疗缺血性卒中的相关基础研究进行汇总分析,发现其可能涉及以下机制:其一,调节肠道菌群组成,抑制致病菌增殖并促进有益菌定植,同时增强肠上皮紧密连接蛋白表达以维持肠道屏障功能,减少肠源性毒素入血;其二,通过神经内分泌调控抑制下丘脑-垂体-肾上腺轴过度激活,降低促炎因子释放,并激活迷走神经介导的抗炎通路;其三,调节短链脂肪酸、氧化三甲胺等肠道菌群代谢产物的动态平衡,改善全身炎症微环境;其四 ...
