[Effect of shikonin on function of rheumatoid arthritis fibroblast like synoviocytes].

To observe the effect of shikonin on the proliferation, migration, adhesion and invasion of rheumatoid arthritis(RA) fibroblast like synoviocytes induced by tumor necrosis factor-α(TNF-α), and to explore its mechanism of action from aspects of protein kinase B(Akt) and mitogen activated protein kinase(MAPK) signaling pathways. TNF-α(20 ng·mL~(-1)) was used in this experiment to induce human RA fibroblast like synovial cell line(MH7 A). After addition of different concentrations of shikonin(0.
