塞米松棕榈酸酯、维生素 B12、利多卡因关节腔内注射对膝关节骨性关节炎患者血清 IL-1，MMP-3 及 TIMP-1 水平的影响

Objective: To investigate the curative efficacy of combined use of dexamethasone palmitate, vitamin B12 and lidocaine in the treatment of knee osteoarthritis and its effects on the serum levels of interleukin-1 (IL-1), matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-1 (TIMP-1). Methods: 84 patients with osteoarthritis of knee were selected from August 2014 to July 2015 in Sixth Affiliated Hospital of Xinjiang Medical University and divided into the observation group and the control group according to the order of admission, 42 cases in each group. The observation group was given intra-articular injection of dexamethasone palmitate, vitamin B12 and lidocaine, and the control group was treated with traditional Chinese medicine. The clinical efficacy was evaluated after treatment. The changes of serum IL-1, MMP-3, TIMP-1 levels and visual analogue (VAS) score were compared before and at 1 months after treatment. Results: After treatment,the total effective rate of observation group was significantly higher than that of the control group (P＜0.05), the serum levels ofIL-1, MMP-3 levels and VAS score were significantly lower than those before treatment, serum TIMP-1 level was obviously higher than that before treatment(P ＜0.05), the serum levels of IL-1, MMP-3 levels were significantly lower in the observation group than those of the control group, while the serum TIMP-1 level was obviously higher than(P＜0.05) Conclusion: Intra-articular injection with dexamethasone palmitate, vitamin B12 and lidocaine could effectively decrease the levels of serum IL-1 and MMP-3, increase the level ofTIMP-1, and relieve the pain in the patients with knee osteoarthritis.
