Aim: To discuss Muscone treatment in Rheumatoid Arthritis Rat Models and relative mechanisms. Materials and methods: Dividing 36 rats as 4 groups as Normal, Model, DMSO and Muscone groups (n = 9). Rats of Model, DMSO and Muscone groups were made Rheumatoid Arthritis model. Muscone group were treated with 2 mg/kg Muscone after modeling. HE staining and Masson staining were used to observe the morphological changes of cartilage tissue, measuring MMP-3 and MMP-9 expression by RT-PCR, Western Blotting (WB) and Immunohistochemistry (IHC). Results: Compared with Model group, the pathological changes of Muscone group was significantly improved and average optical density of collagen fibers was significantly depressed (P < 0.001, respectively) via MMP-3 and MMP-9 proteins significantly depressing (P < 0.001, respectively). Conclusion: Muscone improved Rheumatoid Arthritis by depressing MMP-3 and MMP-9 proteins in vivo study.

We aimed to explore the mechanism underlying microRNA-23-5p from exosomes (exo-miR-23-5p) of BMSCs in rheumatoid arthritis (RA). The candidate related genes of miR-23-5p were screened in RA by bioinformatics analysis through gain- and loss-function method along with analysis of histopathological changes in mice and RAC2 expression as well as the level of pro-inflammatory factors. In vivo RA model was established to detect miR-23-5p’s effect on RA. miR-23-5p level was significantly reduced in RA cells and RAC2 was highly expressed. Expression of RAC2 was inhibited and targeted by miR-23-5p in RA. Exo-miR-23-5p treatment effectively alleviated joint destruction, reduced inflammatory factor secretion in tissues and serum, as well as decreased RAC2 expression in RA model. In conclusion, the miR-23-5p in the BMSC-exo delays the inflammatory response in RA, indicating that it might be a new target for treating RA.
