摘要:


文题释义:
铁死亡:作为一种新型的铁依赖性非凋亡细胞死亡形式,在形态学上呈现出线粒体形态变小、膜密度增加、外膜破损、嵴减少甚至消失的特征。铁死亡的发生主要与胞质内活性氧或脂质过氧化物产生过多、堆积以及铁代谢的异常有关,使得细胞膜发生破损。
纳米药物:其核心是药物的纳米化技术,包括药物的直接纳米化和纳米载药系统。前者通过纳米沉淀技术或超细粉碎技术直接制备纳米药物颗粒;后者则通过将药物溶解、分散、包裹、吸附、偶联等方式与载体结合成为纳米分散体。药物经纳米化后,其物理化学性质以及生物学特性等发生改变,从而影响药物的吸收、分布、代谢和排泄,最终实现增强药物疗效、降低药物不良反应、提高药物效果等目的。

背景:实验证实铁死亡与多种骨科疾病有着密切联系,但调控铁死亡引起骨科疾病的具体机制尚不清晰,目前证据表明,信号通路可能是调控铁死亡发生的重要途径。
目的:概述参与调控骨科疾病(骨关节炎、脊髓损伤、骨质疏松、椎间盘退化、类风湿关节炎、骨肉瘤、激素性股骨头坏死)中铁死亡的相关信号通路,并描述通过调节信号通路的传导,靶向骨科疾病铁死亡途径的关键调节因子。深入研究骨科疾病中铁死亡的调控机制,为此类疾病的防治提供理论依据。
方法:检索PubMed和中国知网等数据库建库至2025年2月发表的铁死亡与骨科疾病的相关文献,英文检索词为“ferroptosis,osteoarthritis,osteoporosis,spinal cord injury,intervertebral disc degeneration,osteosarcomas,rheumatoid arthritis,steroid-induced osteonecrosis of the femoral head”,中文检索词为“铁死亡,骨关节炎,脊髓损伤,骨质疏松,椎间盘退化,类风湿关节炎,骨肉瘤,激素性股骨头坏死”,最终共纳入138篇文献进行综述分析。
结果与结论:①在多种信号通路的调控下,可以诱发细胞内铁离子、活性氧等物质堆积,引起成骨细胞、软骨细胞、骨肉瘤细胞等发生铁死亡,导致微环境发生变化,继而促进或抑制相关骨科疾病的发生;②研究证实信号通路调控铁死亡在骨科疾病的发生机制中具有重要意义;③但是目前信号通路、铁死亡和骨科疾病相互之间的作用机制仍处于初步阶段,需要进行更深入的研究,为治疗骨科疾病提供更多的策略。

Abstract: ACKGROUND: Experiments have confirmed that ferroptosis is closely associated with a variety of orthopedic diseases. However, the specific mechanisms by which the regulation of ferroptosis leads to orthopedic diseases remain unclear. Current evidence suggests that signaling pathways may be an important approach for regulating the occurrence of ferroptosis.
OBJECTIVE: To summarize the relevant signaling pathways involved in the regulation of ferroptosis in orthopedic diseases (osteoarthritis, spinal cord injury, osteoporosis, intervertebral disc degeneration, rheumatoid arthritis, osteosarcoma, steroid-induced osteonecrosis of the femoral head), to describe the key regulators of the ferroptosis pathway in orthopedic diseases through the modulation of the conduction of signaling pathways, and to conduct an in-depth study on the regulatory mechanisms of ferroptosis in orthopedic diseases and provide a theoretical basis for the prevention and treatment of such diseases.
METHODS: Databases including PubMed, Elsevier, Web of Science, and CNKI were searched for relevant literatures on ferroptosis and related orthopedic diseases from the establishment of these databases up to February 2025. The search terms were "ferroptosis, osteoarthritis, osteoporosis, spinal cord injury, intervertebral disc degeneration, osteosarcomas, rheumatoid arthritis, steroid-induced osteonecrosis of the femoral head" in English and Chinese. Finally, 138 articles were included for review.
RESULTS AND CONCLUSION: Under the regulation of multiple signaling pathways, the accumulation of substances such as intracellular iron ions and reactive oxygen species can be induced, leading to ferroptosis in osteoblasts, chondrocytes, osteosarcoma cells, etc., which results in changes in the microenvironment and subsequently promotes or inhibits the occurrence of related orthopedic diseases. Research has confirmed that it is of great significance to clarify the mechanisms by which signaling pathways regulate ferroptosis in orthopedic diseases. However, currently, the interaction mechanisms among signaling pathways, ferroptosis, and orthopedic diseases are still in the preliminary stage, and more in-depth research is needed to provide more strategies for the treatment of orthopedic diseases.
