ABSTRACT
The research progress of acupuncture analgesia in recent years is analyzed to summarize the analgesic mechanism of acupuncture on neuropathic pain. The analgesic mechanism of acupuncture on neuropathic pain is discussed from peripheral level and central level, including peripheral sensitization and immune inflammatory response, changes of ion channel, central sensitization, regulation of cell signal pathway, activation of spinal glial cells, etc. It is suggested that the focus of future research should include conducting in-vitro studies with the help of multi-omics technology to detect the changes of metabolic substances and signal pathway molecules in patients with neuropathic pain before and after acupuncture to further clarify the mechanism of acupuncture analgesia.
