摘要: 目的 研究鹿瓜多肽治疗家兔类风湿性关节炎(RA)的机制。方法 用小牛软骨II型胶原+弗氏完全佐剂0.1 mL于家兔左膝关节腔内多点注射的方法制备RA模型,模型动物分为模型组及低、高剂量鹿瓜多肽(1 mg/d、2 mg/d)治疗组(A、B组),分别计算治疗后1 d、7 d、14 d、21 d足肿胀度,测定关节积液中透明质酸(HA)、白细胞介素-1β(IL-1β),基质金属蛋白酶(MMP-3)及骨形态发生蛋白(BMP)含量。结果 与模型组比较,鹿瓜多肽低、高剂量组14 d、21 d时动物足肿胀度、MMP-3、IL-1β含量明显降低,BMP、HA含量明显升高(P<0.05),低、高剂量组间无明显差异(P>0.05)。结论 鹿瓜多肽可提高家兔关节腔HA合成及BMP分泌,抑制MMP-3及IL-1β对关节滑膜的浸蚀而达到治疗RA的目的。

Abstract: Objective To study the mechanism of the treatment on rheumatoid arthrist (RA) in rabbits by deer melon polypeptide. Methods Calf cartilage II collagen+Freund’s complete adjuvant (0.1 mL) was injected intra-articular in right knee of rabbits to prepare RA model. The model rabbits were randomly divided into model group, low and high dosage deer melon polypeptide group (Group A and B) with 1 mg/d or 2 mg/d. The paw swelling were calculated at 1, 7, 14, 21 days after treatment, the hyaluronic acid (HA), interleukin-1β (IL-1β), matrix metalloproteinase (MMP-3) and bone morphogenetic protein (BMP) content in joint effusion were measured. Results Compared with the model group, paw swelling were occurred in the rabbits of group A and B, MMP-3 and IL-1β were significantly decreased, BMP and HA significantly increased(P<0.05), but no difference between groups A and B (P<0.05). Conclusion The deer melon polypeptide had the treatment effects on RA in rabbit by improving the RA synthesis and BMP secretion in articular, and inhibiting the erosion of MMP-3 and IL-1β on synovial.
