动脉粥样硬化是心脑血管疾病的重要病理基础之一,其病理基础复杂多变,目前公认的病理机制主要为脂代谢紊乱及炎症刺激。铁作为维持生物体生命的重要微量元素,参与了人体中许多的生物过程,如氧代谢、脂代谢及细胞呼吸等。近期有关铁死亡的研究将铁与动脉粥样硬化联系起来,阐明铁可能参与动脉粥样硬化的发生发展过程,本文将综述有关铁代谢及其在动脉粥样硬化发生发展中可能的机制的文章并探讨未来针对动脉粥样硬化的可能潜在治疗靶点。Atherosclerosis is one of the important pathological bases of cardiovascular and cerebrovascular diseases. Its pathological basis is complex and changeable. At present, the recognized pathological mechanism is mainly lipid metabolism disorder and inflammatory stimulation. Iron, as an important trace element for maintaining biological life, participates in many biological processes in the human body, such as oxygen metabolism, lipid metabolism, and cellular respiration. Recent studies on ferroptosis have linked iron with atherosclerosis, and clarified that iron may participate in the occurrence and development of atherosclerosis. This article will review studies on iron metabolism and its possible mechanism in the occurrence and development of atherosclerosis, and explore potential therapeutic targets for atherosclerosis in the future.
目前,尽管有机械循环支持及血运重建等技术不断发展并应用于临床,但很多难治性危重疾病仍保持较高的死亡等不良事件风险。无创全身阻抗心输出量监测系统(NICaS)是一种新型血流动力学导航仪,可连续准确地进行心功能和循环血量监测,帮助医生进行容量管理及药物调整等,不仅可以减少心衰、肺水肿及死亡的发生,还可以有效降低机械通气事件,提高患者生存率。其价值不仅在心血管系统中得到证实,在其他各系统中的应用也得到了充分肯定。本文综述了NICaS在心血管疾病及其他各系统相关研究中的应用及进展。At present, despite the continuous development and clinical application of mechanical circulatory support and revascularization technologies, many refractory critical diseases still maintain a high risk of adverse events such as death. Noninvasive Cardiac System (NICaS) is a new hemodynamic navigation device, which can continuously and accurately monitor cardiac function and circulating blood volume, help doctors to carry out volume management and drug adjustment, etc., which can not only reduce the occurrence of heart failure, pulmonary edema and death, but also effectively reduce mechanical ventilation events and improve patient survival. Its value has been confirmed not only in the cardiovascular system, but also in other systems. This article reviews the application and progress of NICaS in cardiovascular diseases and other system-related studies.
