Abstract: In order to screen for the early biomarkers of transient ischemic attack (TIA) in vivo, this study was conducted to explore the metabolomic characteristics of urine in rat models of TIA caused by bilateral common carotid artery occlusion. Seven important urine metabolic markers of TIA injury, including L-malic acid, D-glucurono-6,3-lactone, L-threonine, L-valine, L-gulonolactone, ascorbate, and phosphoenolpyruvic acid, were found and identified, which were mainly involved in ascorbic acid metabolism, pyruvate metabolism and branched chain amino acid metabolism, and involved in regulating oxidative stress, inflammatory response and neuroprotection. In this study, rapid resolution liquid chromatography-mass spectrometry was used to screen in metabolic biomarkers of TIA, providing a scientific basis for the early diagnosis and treatment of stroke.
