[Research progress on hepatotoxicity of acetaminophen]

Acetaminophen (APAP) is a widely used antipyretic and analgesic drug that is safe and effective in the therapeutic doses, but overdose may cause hepatotoxicity and even acute liver failure (ALF). Finding reliable biomarkers for APAP toxicity is not only a hot spot of current research, but also a problem that needs to be solved urgently. Clinicians should consider the existence of APAP hepatotoxicity when using APAP treatment, and explain that APAP may have a certain degree of dose dependence. This paper reviews the most promising biomarkers currently being evaluated, and expounds their application in the field of APAP hepatotoxicity, as well as the mechanism of mitochondrial damage and mitochondrial autophagy, thereby contributing to the diagnosis, prognosis, mechanism and research progress of therapeutic targets of APAP hepatotoxicity.对乙酰氨基酚（APAP）是一种广泛应用的解热镇痛药，在治疗剂量时是安全有效的，但过量时会造成肝毒性，甚至急性肝功能衰竭。寻找可靠的APAP毒性生物标志物既是当前研究的热点，也是当前亟需解决的难题。临床医师在使用APAP治疗时，应考虑APAP肝毒性的存在，并说明APAP可能有一定程度的剂量依赖性。现对目前正在评估的生物标志物进行综述，阐述了它们在APAP肝毒性领域的应用及其肝毒性的线粒体损伤机制、线粒体自噬机制，从而有助于APAP肝毒性的诊断、预后、机制研究以及开发其治疗靶点。.
