Stroke is a major reason for disability and the second highest cause of death in the world. When a patient is admitted to a hospital, it is necessary to identify the type of stroke, and the likelihood for development of a recurrent stroke, vascular dementia, and depression. These factors could be determined using different biomarkers. Metabolomics is a very promising strategy for identification of biomarkers. The advantage of metabolomics, in contrast to other analytical techniques, resides in providing low molecular weight metabolite profiles, rather than individual molecule profiles. Technically, this approach is based on mass spectrometry and nuclear magnetic resonance. Furthermore, variations in metabolite concentrations during brain ischemia could alter the principal neuronal functions. Different markers associated with ischemic stroke in the brain have been identified including those contributing to risk, acute onset, and severity of this pathology. In the brain, experimental studies using the ischemia/reperfusion model (IRI) have shown an impaired energy and amino acid metabolism and confirmed their principal roles. Literature data provide a good basis for identifying markers of ischemic stroke and hemorrhagic stroke and understanding metabolic mechanisms of these diseases. This opens an avenue for the successful use of identified markers along with metabolomics technologies to develop fast and reliable diagnostic tools for ischemic and hemorrhagic stroke.

缺血性卒中的代谢组学和代谢物

中风是导致残疾的主要原因,也是世界上第二大死因。当患者入院时,有必要确定中风的类型,以及发展为复发性中风、血管性痴呆和抑郁症的可能性。这些因素可以使用不同的生物标志物来确定。代谢组学是一种非常有前途的生物标志物鉴定策略。与其他分析技术相比,代谢组学的优势在于提供低分子量代谢物谱,而不是单个分子谱。从技术上讲,这种方法基于质谱和核磁共振。此外,脑缺血期间代谢物浓度的变化可能会改变主要的神经元功能。已经确定了与脑缺血性中风相关的不同标志物,包括导致这种病理的风险、急性发作和严重程度的标志物。在大脑中,使用缺血/再灌注模型 (IRI) 的实验研究表明能量和氨基酸代谢受损,并证实了它们的主要作用。文献资料为识别缺血性脑卒中和出血性脑卒中的标志物以及了解这些疾病的代谢机制提供了良好的基础。这为成功使用已识别的标志物以及代谢组学技术开辟了一条途径,以开发用于缺血性和出血性中风的快速可靠的诊断工具。使用缺血/再灌注模型 (IRI) 的实验研究表明能量和氨基酸代谢受损,并证实了它们的主要作用。文献资料为识别缺血性脑卒中和出血性脑卒中的标志物以及了解这些疾病的代谢机制提供了良好的基础。这为成功使用已识别的标志物以及代谢组学技术开辟了一条途径,以开发用于缺血性和出血性中风的快速可靠的诊断工具。使用缺血/再灌注模型 (IRI) 的实验研究表明能量和氨基酸代谢受损,并证实了它们的主要作用。文献资料为识别缺血性脑卒中和出血性脑卒中的标志物以及了解这些疾病的代谢机制提供了良好的基础。这为成功使用已识别的标志物以及代谢组学技术开辟了一条途径,以开发用于缺血性和出血性中风的快速可靠的诊断工具。
