Abstract Objective: To study the therapeutic effect of thalidomide on rheumatoid arthritis and its effect on serum levels of Cystatin C (Cys-C)and vascular endothelial growth factor (VEGF). Methods: 96 rheumatoid arthritis patients who received therapy from March 2017 to February 2018 in our hospital were selected as research objects. According to random number table method,those patients were divided into the observation group (n=50) and the control group (n=46). The control group was treated with methotrexate, and the observation group was treated with both methotrexate and thalidomide. Then the therapeutic efficacy, improvement of clinical symptoms, levels of related indicators, bone metabolism indicators, serum levels of Cys-C and vascular endothelial growth factor of two groups after treatment were compared. Results:After treatment, the total effective rate of observation group was significantly higher than that of control group[96.00%(48/50)vs76.08%(35/46)](P<0.05). Joint tenderness index, joint swelling index and morning stiffness time were significantly lower than those in the control group[(1.71±0.50)vs (5.90±1.42),(1.42±0.32)vs (5.61±1.27),(8.03±1.20)min vs (21.74±5.40)min](P<0.05). The levels of ESR and CRP were significantly lower than those of the control group[(3.05±0.92)mm/h vs (17.43±4.13)mm/h,(4.02±0.67)mg/L vs (12.01±1.35)mg/L](P<0.05). N-MID and T-PINP were significantly higher than those in the control group[(20.13±3.72)mg/mL vs (14.63±2.70)mg/mL,(47.30±6.51)mg/mL vs (38.46±5.17)mg/mL](P<0.05). The level of beta-CTX was significantly lower than that of the control group[(0.46±0.10)pg/mL vs (0.72±0.16)pg/mL](P<0.05). Cys-C and vascular endothelial growth factor levels were significantly lower than those in the control group[(0.67±0.12)mg/L vs (1.35±0.30)mg/L,(32.76±7.42)μmol/L vs(50.95±10.64)μmol/L](P<0.05).Conclusion:Thalidomide can improve the clinical symptoms and bone metabolism of patients with rheumatoid arthritis. It can regulate immunity, reduce the levels of Cys-C and VEGF. It has less adverse reactions and is safe and reliable.
