摘要: 目的:利用代谢组学技术,从内源性物质的代谢变化角度探讨糖尿病状态下阿司匹林治疗中血小板高反应(HAPR)的发生机制。方法:本研究采用高脂饲料联合链脲佐菌素建立2型糖尿病(T2DM)小鼠模型,随后将小鼠按体质量随机分为正常组、T2DM组、正常+阿司匹林组、T2DM+阿司匹林组。通过气相色谱-飞行时间质谱(GC-TOF/MS)检测不同组别小鼠血浆内源性代谢物,利用多变量统计方法对数据进行分析。结果:长期给予阿司匹林的T2DM雌性小鼠的血小板表面CD62P及血浆血栓素(TXB2)/6-keto-PGF1α的比值与模型组相比无显著改变,这表明在T2DM雌性小鼠上,阿司匹林药效降低,发生HAPR;正常组和正常+阿司匹林组之间代谢组别的趋离程度明显大于T2DM和T2DM+阿司匹林组,进一步证实T2DM雌性小鼠发生了HAPR;生化代谢通路分析提示T2DM小鼠HAPR的发生与糖酵解或糖异生作用、丙酮酸代谢、柠檬酸循环、抗坏血酸代谢、花生四烯酸等代谢通路的增强密切相关。结论:代谢组检测中筛选所获得的差异代谢物提示了糖尿病状态下HAPR的发生涉及不同代谢途径的改变,这为进一步阐明糖尿病状态下HAPR的生物学机制奠定了物质基础。

Abstract: AIM: To explore the underlying mechanism of aspirin-related high on-aspirin platelet reactivity (HAPR) in diabetic state from the perspective of endogenous metabolic changes in metabolomics. METHODS:Type 2 diabetes mellitus (T2DM) mice model was established by the combination treatment of high-fat diet and streptozotocin injections. Mice were randomly divided into Normal group, T2DM group, Normal+aspirin group and T2DM+aspirin group. GC/TOF-MS was used to determine the plasmatic endogenous metabolites of mice. The data were analyzed applying multivariate statistical method. RESULTS:The expression of platelet CD62P and ratio of TXB2/6-keto-PGF1α in the plasma of female T2DM mice showed no significant difference compared with that of the model group. The degree of divergence between normal and normal+aspirin groups was significantly greater than that between T2DM and T2DM+aspirin groups. Biochemical metabolic pathway analysis revealed that HAPR in diabetic mice was linked to glycolysis, gluconeogenesis, pyruvate metabolism, citric acid cycle, ascorbic acid metabolism, and arachidonic acid metabolic pathways. CONCLUSION:The different metabolites obtained in metabolome assay suggests that the HAPR in diabetic state involved several different metabolic pathways, which can better elucidate the biological mechanism of diabetes-associated HAPR.
