摘要

The nonstructural protein NS1 of human parvovirus B19 (B19) is known to exacerbate disease activity in systemic lupus erythematosus (SLE). However, no specific medicine for B19 infection is available. The roots of Gentiana macrophylla Pall. (GM), the traditional Chinese medicine "Qinjiao," have been used for centuries to treat rheumatic disease, including SLE. Herein, we aimed to investigate the effects of GM root extract (100 and 300 mg/kg body weight) on B19-NS1-exacerbated liver injury in NZB/W F1 mice; liver tissues were assessed by hematoxylin-eosin staining and immunoblotting. The GM root extract significantly decreased B19-NS1-exacerbated liver inflammation by suppressing the expressions of hepatic inducible nitric oxide synthase, cyclooxygenase type 2 (COX-2), interleukin (IL)-1β proteins, values of serum asparate transaminase (AST) and alanine transaminase (ALT), and lymphocyte infiltration (P <.05). It also significantly reduced the B19-NS1-exacerbated hepatic matrix metalloproteinase-9 (MMP-9) and urokinase plasminogen activator (uPA) expressions by downregulating tumor necrosis factor (TNF)-α/NF-κB (p65) signaling. These findings suggest a therapeutic potential of GM root extract against B19-NS1-exacerbated liver inflammation in SLE.
