Abstract	Acute alcoholism is a major cause of cirrhosis and liver failure around the world. Selenium (Se) is an essential micronutrient promoting liver health in humans and animals. Selenoprotein P (SelP) is a glycoprotein secreted within the liver, which interacts with cytokines and the growth factor pathway to provide protection for hepatic cells. The present study was conducted to confirm the effect and mechanism of Se and SelP action in livers affected by acute alcoholism. In this study, a mouse model of acute alcoholism, as well as a hepatocyte model, was successfully established. The Se content of the liver was detected by atomic fluorescence spectrophotometry. The expression of messenger RNA (mRNA) was analyzed by quantitative polymerase chain reaction (qPCR). The protein expression of inflammatory factors was detected by ELISA. The other proteins were analyzed by western blotting. The results showed that pathological damage to the liver was gradually weakened by Se-supplementation, which was evaluated by hematoxylin and eosin (H&E) and TUNEL staining. Se-supplementation inhibited expression of pro-inflammatory factors TNF-α and IL-1β and promoted production of anti-inflammatory cytokine IL-10 in the liver with acute alcoholism. Se-supplementation also prevented the apoptosis of hepatocytes by suppressing the cleavage of caspases-9, 3, 6, 7, and poly(ADP-ribose) polymerase (PARP). Through correlational analysis, it was determined that the effects of Se-supplement were closely related to SelP expression, inflammatory cytokines, and apoptosis molecule production. The sienna of SelP further confirmed the protective action of Se-supplementation on the liver and that the mechanism of SelP involves the regulation of inflammatory cytokines and apoptosis molecules in acute alcoholism. These findings provide information regarding a new potential target for the treatment of acute alcoholism.
