It is found that acupuncture can significantly improve the clinical symptoms of rheumatoid arthritis (RA) such as pain and joint stiffness, and improve rheumatoid factor, high-sensitivity CRP, ESR and other clinical indicators. It can inhibit the proliferation of synovial cells, the apoptosis of chondrocytes, and regulate polarization balabce of mononuclear macrophages, T cells, as well as inhibit the inflammatory function of multiple immune cells, in order to improve inflammation state of RA joints. In clinical treatment of RA, bladder meridian, stomach meridian, spleen meridian , and Governor Vessel are mostly selected. Acupoints with the efficacy of warming meridian, dispelling coldness and dredging collaterals were commonly selected such as Zusanli (ST36), Yanglinquan (GB34), Dazhui (GV14), Quchi (LI11). Several researches have proved that combined therapy of acupuncture and medicine is worthy promotion in clinic.

Acupuncture is often used in the clinical treatment of Rheumatoid arthritis(RA).However,its mechanism of action remains unclear.DNA sensing activates innate immunity and induces inflammatory responses through the cyclic GMP-AMP synthase(cGAS)/stimulator of interferon genes(STING)pathway.Meanwhile,STING mediated type-Ⅰinterferons(IFNs-Ⅰ)signaling has been proved to be a key regulatory molecule of nociception,which has become a potential target for RAtreatment.This article reviews the molecular mechanisms and functions of cGAS/STING activation and signal transduction,with particular emphasis on the antinociception effect of this signaling pathway in neuro-immune interactions in the peripheral nervous system,and envisage new ideas for the study of the neuroimmune mechanism of acupuncture in improving RA,which provides a new research direction for the treatment of RA and other autoimmune diseases related to immune disorders.It also provides new strategies and methods for the clinical transformation of intervention STING pathway.
