Abstract:
Objective To analyze the expression and significance of BCAS3 and RFX3 proteins in mac-rophages from gout stone tissues.Methods Thirty gout stone excision specimens in this hospital from April 2019 to December 2022 were collected as the experimental group,and during the same period 25 specimens of synovial hyperplasia accompanied by foreign body giant cell reaction after joint replacement and 5 specimens of fat necrosis accompanied by macrophage hyperplasia served as the control group.The blood uric acid level of the control group was normal.Immunohistochemical staining was applied to conduct CD68,CD163,BCAS3 and RFX3 antibodies staining in all specimens.CD68 and CD163 were used to locate macrophages in tissues. The expression levels of BCAS3 and RFX3 in macrophages were detected.The expressions of the two antibod-ies and their correlation with age,sex and blood uric acid level were analyzed.The receiver operating character-istic (ROC) curve was used to evaluate the diagnostic value of the both on gout.Results The expression lev-els of BCAS3 and RFX3 in the experimental group were significantly higher than those in the control group (P<0.05).The BCAS3 and RFX3 protein expression levels in the control group had no statistical difference between the different sexes (P>0.05).The expression level of BCAS3 protein in the experimental group was positively correlated with the RFX3 protein expression (P<0.05);the uric acid level in the experimental group was positively correlated with the expression level of BCAS3 and RFX3 protein (P<0.05).The blood uric acid level in the control group had no correlation with BCAS3 and RFX3 protein (P>0.05).The age in the two groups had no correlation with the BCAS3 and RFX3 protein (P>0.05).The area under the curve (AUC),sensitivity and specificity of RFX3 were 0.935,96.55％ and 86.67％ respectively,which were higher than 0.742,70.00％ and 80.00％ of BCAS3.RFX3 had the higher diagnostic value for gout.Conclusion High expression of BCAS3 and RFX3 proteins in macrophages may participate in the pathogenesis of gout.There may be some synergistic promoting effect between the two.The diagnostic value of RFX3 for gout is higher than that of BCAS3.
