[Research Progress on Protective Effect of Traditional Chinese Medicine and Natural Medicine on Methotrexate-Induced Liver Toxicity].

Methotrexate(MTX) is a commonly used antimetabolite, which can be used in the treatment of a variety of diseases. However, hepatotoxicity in the use of MTX severely limits its clinical use. Therefore, how to prevent and treat hepatotoxicity of MTX has become an urgent clinical problem. This paper summarizes and analyzes relevant literatures on the prevention and treatment of hepa-totoxicity caused by MTX with traditional Chinese medicines and natural medicines in recent years. MTX-induced hepatotoxicity mechanisms include folate pathway, oxidative stress damage and adenosine pathway, of which oxidative stress theory is the main research direction. A total of 14 kinds of traditional Chinese medicine and natural medicine extracts including white peony root, and 21 kinds of natural monomer compounds, including berberine, play an anti-MTX-induced hepatotoxic effect by resisting oxidative stress, inhibiting inflammation and regulating signal pathways. According to current studies on the prevention and treatment of hepatotoxicity induced by MTX with traditional Chinese medicines and natural medicines, there are insufficiencies, such as partial and superficial mechanism studies, inadequate combination of experimental research and clinical practice, non-standard experimental design and lack of application of advanced technologies and methods. This paper systematically reviewed the effects and mechanisms of traditional Chinese medicines and natural medicines against hepatotoxicity induced by MTX and defined current studies and deficiencies, in the expectation of proposing new study strategies and directions and providing scientific basis for rational clinical use of MTX and development of new drugs against MTX hepatotoxicity.
