ABSTRACT
This article introduced the main biological mechanisms of acupuncture promoting nerve function recovery after spinal cord injury, which include inhibition of inflammation and oxidative stress, alleviation of neuropathic pain, increase of neurotrophic active sub-stance, regulation of cell survival/apoptosis gene and neural regeneration pathway.
ABSTRACT
Methotrexate (MTX)has dual effects of anti-inflam-matory and immune suppression,and its pharmacological mecha-nism is complex,diverse and synergistic.This paper summari-zes the main anti-inflammatory mechanism of low-dose MTX,in-cluding inhibition of JAK/STAT pathway,inhibition of inflam-matory reaction and immune response,increasing the accumula-tion of adenosine and the function of intracellular metabolites (methotrexate polyglutamate).In addition,low-dose MTX can inhibit oxidation by decreasing the level of lipid peroxidation, suppress the inflammatory response to secondary spinal cord in-jury,reduce spinal cord ischemia reperfusion injury and neuro-pathic pain,thus playing a neuroprotective role by a series of pharmacological mechanism.The anti-inflammatory mechanism of low-dose MTX and its application in spinal cord injury were reviewed,to guide the further research on the anti-inflammatory effect of MTX,and provide a theoretical basis for new drugs for clinical treatment of spinal cord injury.
