The expressions of TLR2, TLR4, NF-κB, MyD88, and TRAF6 protein in the synovium of Groups M1 and M2 were significantly higher than those of Group S (p < 0.01) whereas the expressions of TLR2, TLR4, NF-κB, MyD88, and TRAF6 protein in the synovial tissue after EA treatment were significantly lower than those of corresponding groups M1 and M2 (p < 0.01). Here, TRAF6 is linked to Esophageal atresia.
