To observe the effect of acupuncture on nuclear factor kappa-B(NF-κB)signaling pathway in patients with rheumatoid arthritis (RA), so as to explore the mechanism of acupuncture in the treatment of RA.
A total of 120 RA patients admitted to the Xinyu Hospital of Traditional Chinese Medicine in Jiangxi Province from June 2018 to June 2019 were selected and randomly divided into a control group and a treatment group, with 60 cases in each group. The patients in the control group received oral administration of Methotrexate, (10-15) mg/time, once a week, for a total of 10 weeks. On the basis of oral administration of Methotrexate, patients in the treatment group were treated with acupuncture at Quchi(LI11), Zusanli(ST36), Taichong(LR3), Hegu(LI4), Shenshu(BL23), Geshu(BL17) and Dazhui(GV14) once daily. The treatment was conducted 6 consecutive times as a course for 10 courses. The serum C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), pain visual analog scale (VAS) score, number of swollen joints, and morning stiffness time before and after treatment were compared between the two groups. The expression levels of inflammatory related factors and NF-κB p65 protein in the synovial fluid were detected by enzyme-linked immunosorbent assay and Western blot separately.
After treatment, both groups had significant decrease in CRP, ESR, VAS score, number of swollen joints and morning stiffness time, levels of NF-κB p65 protein, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 (
Acupuncture can inhibit the expression of NF-κB signaling pathway in RA patients, regulate the levels of related inflammatory factors, and thus improve the symptoms of RA patients.
