Abstract:
Objective:To investigate the protective effect of moxibustion on joints and its influence on the expression levels of S100 calcium binding protein A8(S100A8),S100 calcium binding protein A9(S100A9),serum amyloid A1(SAA1),and related inflammatory factors in rats with adjuvant arthritis(AA).Methods:Forty Wistar rats were randomly divided into a normal group,a model group,a moxibustion group,and a medication group,with 10 rats in each group.Except for the normal group,AA models were established in the other three groups by exposing rats to wind-cold-dampness environmental conditions combined with complete Freund's adjuvant.After successful modeling,the moxibustion group received moxibustion intervention,while the medication group was administered tripterygium glycosides tablets via oral gavage.The normal and model groups underwent similar handling and fixation without additional interventions.After 15 d of intervention,hematoxylin-eosin staining was used to assess pathological changes in the knee joint synovial membrane.Western blotting was performed to detect the protein expression of S100A8,S100A9,and SAA1 in the synovial tissue.Enzyme-linked immunosorbent assay was used to measure the serum levels of interferon(IFN)-γ,interleukin(IL)-6,and IL-23.Results:Compared to the normal group,the model group exhibited significantly increased protein expression of S100A8,S100A9,and SAA1 in the knee joint synovial tissue,as well as elevated serum levels of IFN-γ,IL-6,and IL-23(P<0.01).Histopathological analysis revealed marked synovial hyperplasia and extensive infiltration of inflammatory cells in the model group.Compared to the model group,both the moxibustion and medication groups showed significant reductions in the protein expression of S100A8,S100A9,and SAA1 in the synovial tissue,as well as decreased serum levels of IFN-γ,IL-6,and IL-23(P<0.01).Additionally,synovial tissue in these two groups displayed minimal hyperplasia and only mild inflammatory cell infiltration.Notably,compared to the moxibustion group,the medication group exhibited significantly higher protein expression of S100A9 in the synovial tissue(P<0.05),while no significant differences were observed in the expression of S100A8,SAA1,or serum levels of IFN-γ,IL-6,and IL-23(P>0.05).Both intervention groups showed comparable degrees of synovial inflammation,clear tissue structure,and no obvious hyperplasia.Conclusion:Moxibustion can alleviate joint swelling and reduce inflammatory responses in AA rats.Its mechanism may involve regulating the protein expression of S100A8,S100A9,and SAA1 in the knee joint synovial tissue.
