Abstract: Objective:To observe the effect of electroacupuncture (EA) on tumor necrosis factor-α (TNF-α) and vascular endothelial growth factor (VEGF) in peripheral blood and joint fluid of collagen-induced arthritis (CIA) rats.Methods:After CIA rat models were successfully established,the rats were given corresponding intervention treatments.The levels of TNF-α and VEGF in peripheral blood and joint fluid were measured.Results:The levels of TNF-α and VEGF levels in peripheral blood and joint fluid of CIA rats were higher than those of normal group (P<0.05); EA treatment significantly decreased the index levels,of significant difference compared with those before treatment (P<0.05),as well as the model group (P<0.05).Conclusion:EA can significantly decrease the TNF-α and VEGF levels in peripheral blood and joint fluid of CIA rats,and helps restrain further development of the disease.
