BACKGROUND:Neuroinflammation is a major cause of exacerbation after spinal cord injury.In recent years,pyroptosis has received much attention due to its remarkable pro-inflammatory features.Some of these natural products can significantly inhibit the inflammatory response and improve the damaged nerve function by regulating the level of pyroptosis after spinal cord injury,which provides a new therapeutic idea for spinal cord injury.OBJECTIVE:To summarize the mechanism of action of natural products in regulating pyroptosis for the treatment of spinal cord injury,with a view to providing lessons and references for future research on the treatment of spinal cord injury.METHODS:The search terms"spinal cord injury,pyroptosis,inflammasome,natural products,natural compounds,traditional Chinese medicine"in Chinese and English were used to search for relevant literature since the establishment of the database up to September 2024 in the databases of PubMed,Web of Science,WanFang,and CNKI.According to the inclusion and exclusion criteria,75 relevant articles were finally obtained.RESULTS AND CONCLUSION:(1)Pyroptosis is an important pro-inflammatory pathway in spinal cord injury,and controlling pyroptosis is an effective way to improve damaged nerve function.(2)Some natural products can regulate pyroptosis via the NLRP3/Caspase-1 classical pyroptosis pathway,the NF-κB-related pathway,other upstream pathways such as Nrf2/HO-1,and autophagy,thereby affecting the level of tissue inflammation and accelerating neurological recovery after spinal cord injury.(3)The anti-pyroptosis effects of these natural products are mostly dependent on the NLRP3 classical pyroptosis pathway,and there is a lack of studies on other pyroptosis pathways.(4)There are still many problems in this field,such as the fact that these natural products are not currently supported by evidence from appropriate clinical studies.(5)The natural product has great potential in regulating pyroptosis and is expected to be a powerful weapon in the treatment of spinal cord injury.

BACKGROUND:Rheumatoid arthritis is a complex autoimmune disease characterized by joint swelling,pain,and progressive damage.The basic pathological changes include synovitis and pannus formation,with T lymphocyte infiltration being the key to its pathogenesis.In recent years,the application of traditional Chinese medicine(TCM)monomers in the treatment of rheumatoid arthritis has attracted increasing attention.They have shown long-lasting effcacy and fewer side effects by regulating the T helper cell 17(Th17)/regulatory T cells(Treg)balance in the treatment of rheumatoid arthritis.OBJECTIVE:To discuss the mechanisms by which TCM monomers regulate the Th17/Treg balance to treat rheumatoid arthritis,based on the latest basic research,providing a solid theoretical basis for future applications of TCM in the treatment of rheumatoid arthritis.METHODS:Using keywords such as"rheumatoid arthritis,Th17/Treg,traditional Chinese medicine,Chinese herbal monomer,"and their Chinese equivalents,literature searches were conducted in PubMed,Web of Science,Embase,Cochrane,VIP,CBM,CNKI,and WanFang databases for relevant studies from their inception to August 2024.Inclusion and exclusion criteria were established,and the articles were screened by reading the titles,abstracts,and full texts.Finally,57 relevant articles were included.RESULTS AND CONCLUSION:(1)TCM monomers have immunoregulatory effects in the treatment of rheumatoid arthritis.They exert therapeutic effects by maintaining the Th17/Treg balance through the regulation of transcription factors,cytokines,signaling pathways,and miRNAs.(2)There may be synergistic effects among some TCM monomers,but the specific mechanisms and enhancement effects in regulating the Th17/Treg balance require further exploration.(3)Regulating the Th17/Treg balance using TCM monomers may become a key clinical therapy for the treatment of rheumatoid arthritis.
