Polydatin is a natural extract used in traditional Chinese medicine, which leads to a marked improvement in the microcirculation perfusion and enhances the animal myocardial contraction force. The present study aimed to determine whether an effective treatment of polydatin ameliorates the symptoms of collagen-induced arthritis (CIA), and also to explore the potential mechanism. Male DBA/1J mice were induced into CIA model mice. The administration of polydatin effectively suppressed CIA in mice. The serum levels of malondialdehyde (MDA), superoxide dismutase (SOD), tumor necrosis factor-alpha (TNF-alpha) and interleukin 1 beta (IL-1 beta) were effectively increased following the induction of CIA in the model mice compared with the control group. The elevated serum levels of MDA, SOD, TNF-alpha and IL-1 beta were markedly suppressed by the effective treatment of polydatin in CIA mice, compared with the CIA model group. However, an increase in the level of matrix metalloproteinase-9 (MMP-9) was markedly induced in the CIA mice compared with the control group. As compared with the CIA group, the expression of MMP-9 was substantially reduced by the effective treatment of polydatin. Taken together, the effective treatment of polydatin ameliorated the symptoms of CIA through an exertion of its antioxidative and anti-inflammatory effects, and also via activation of the expression of matrix metalloproteinase-9 (MMP-9) in mice.
