Acute ischemic stroke (AIS) not only affects the brain but also has significant implications for peripheral organs through neuroendocrine regulation. This reciprocal relationship influences overall brain function and stroke prognosis. Recent research has highlighted the importance of poststroke liver changes in determining patient outcomes. In our previous study, we investigated the relationship between stroke and liver function. Our findings revealed that the prognostic impact of stress-induced hyperglycemia in patients undergoing acute endovascular treatment for acute large vessel occlusion is closely related to their preexisting diabetes status. We found that the liver contributes to stress hyperglycemia after AIS by increasing hepatic gluconeogenesis and decreasing hepatic insulin sensitivity. These changes are detrimental to the brain, particularly in patients without diabetes. Furthermore, we examined the role of bilirubin, a byproduct of hepatic hemoglobin metabolism, in stroke pathophysiology. Our results demonstrated that blood bilirubin levels can serve as predictors of stroke severity and may hold therapeutic potential for reducing oxidative stress-induced stroke injury in patients with mild stroke. These results underscore the potential role of the liver in the oxidative stress response following AIS, paving the way for further investigation into liver-targeted therapeutic strategies to improve stroke prognosis and patient outcomes.
急性缺血性卒中(AIS)不仅会影响大脑,还会通过神经内分泌调节对周围器官产生重大影响。这种相互关系会影响整体脑功能和卒中预后。最近的研究强调了卒中后肝脏变化在决定患者预后方面的重要性。在我们之前的研究中,我们调查了卒中和肝功能之间的关系。我们的研究结果显示,急性大血管闭塞患者接受急性血管内治疗时,应激性高血糖的预后影响与其既往糖尿病状态密切相关。我们发现,AIS后肝脏通过增加肝糖异生和降低肝脏胰岛素敏感性导致应激性高血糖。这些变化对大脑有害,尤其是在非糖尿病患者中。此外,我们研究了肝血红蛋白代谢的副产物胆红素在卒中病理生理学中的作用。我们的结果表明,血胆红素水平可作为卒中严重程度的预测指标,对于减轻轻度卒中患者氧化应激所致的卒中损伤可能具有治疗潜力。这些结果强调了肝脏在AIS后氧化应激反应中的潜在作用,为进一步研究以肝脏为靶点的治疗策略以改善卒中预后和患者结局铺平了道路。
