| 中文摘要: |
| 目的：本研究采用超高效液相色谱-串联四极杆飞行时间质谱（UPLC-Q-TOF-MS/MS）技术，探讨了金芪降糖片（JQJT）治疗2型糖尿病（T2DM）的作用机制。方法：采用高糖高脂饮食联合链脲佐菌素（STZ）诱导T2DM模型，检测大鼠体质量、血糖等指标。利用UPLC-Q-TOF-MS/MS分析对照组、模型组、阳性药组、正常给中药组、模型给中药组大鼠的血清样品代谢谱。采用主成分分析（PCA）和正交偏最小二乘法判别分析（OPLS-DA）对差异代谢物进行筛选和鉴别。结果：从血清中筛选出15个潜在的生物标志物，并利用Met PA构建了1条相关的代谢通路，即甘油磷脂代谢通路。在2型糖尿病（T2DM）大鼠血清中，溶血磷脂酰胆碱（LysoPC）（18:0）和LysoPC（16:1）等9种代谢物下调，LysoPC（18:1）和LysoPC（20:0）等6种代谢物上调。结论：金芪降糖片给药组能使这15种潜在的生物标志物有良好的回调趋势，推测金芪降糖片可能通过调节脂代谢紊乱而缓解T2DM的进程。 |
| English Summary: |
| This study aims to explore the mechanism of Jinqi Jiangtang Tablets(JQJT) in the treatment of type 2 diabetes mellitus(T2DM) by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS).Methods:To be specific，T2DM was induced in rats with high-sugar and high-fat diet and streptozotocin(STZ) and the body weight，blood glucose，and other indicators were detected.UPLC-Q-TOF-MS/MS was employed to analyze the metabolic profiles of serum samples in control group，model group，positive drug group，JQJT normal group，and JQJT model group.Principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were used to screen and identify the differential metabolites.Results:Metabolic profiling revealed 15 metabolites as the potential biomarkers distinguishing rats in model group from those in control group.The metabolomics pathway analysis(MetPA) was applied to investigate the underlying metabolic pathways.A major metabolic pathway was glycerophosphatide metabolism.Nine metabolites such as LysoPC(18:0) and LysoPC(16:1) were down-regulated in T2DM rats，and six metabolites such as LysoPC(18:1) and LysoPC(20:0) were up-regulated.Conclusion:Moreover，the fifteen biomarkers of each administration group had a trend of returning to the levels in rats in control group.The significantly-altered metabolite levels indicated that JQJT can improve the progression of T2DM by alleviating lipid metabolism disorder. |
