Task: Intent Identification
Input (English): Simvastatin has lung vascular-protective effects via augmentation of endothelial barrier function. Accordingly, on the basis of our previous study, we hypothesized that endothelial cell (EC) protection by simvastatin is dependent on the stabilization on cytoskeletons.', 'Sixty C57BL/6 mice were divided into two experimental groups: LPS group (L group) and LPS+simvastatin treated group (L+S group). All mice in these two groups received an intraperitoneal injection of LPS (10\u200amg/kg/d). Simvastatin was administered intraperitoneally immediately after the LPS injection in animals of the L+S group at a dose of 20\u200amg/kg/day. Lung injury degree and the protective effects of simvastatin against LPS-induced lung injury were assessed at the time-points of 24, 48 and 72\u200ah post-injection. Serum alanine transaminase (ALT), serum creatinine (Scr) were identified to assess the hepatic and renal side-effects of simvastatin.', 'LPS inhibited the cytoskeletal regulating proteins of Cdc42 and PAK4, and was accompanied by an increased circulating endothelial microparticles (EMPs) level. The adherent junction (AJ) protein of VE-cadherin was also decreased by LPS, and was accompanied by a thickening alveolar wall, increased lung W/D values and high albumin concentration in bronchoalveolar lavage (BAL). Protective effects of simvastatin against LPS-induced lung injury were illustrated by regulating and stabilizing cytoskeletons, as well as intercellular AJs. The values of ALT and Scr were all lower than the common upper limits according to assay kits.
