MSTN and sarcopenia: We also found that the serum levels of interleukin-1β, matrix metalloprotein-9, tumor necrosis factor-α, interleukin-6, myostatin, and C-reactive protein were significantly reduced by SJZD, which suggested the roles of SJZD in inflammation.<h4>Conclusion</h4>SJZD improved muscle strength, quality, and functions in sarcopenia patients by reducing peripheral blood inflammation.
