| Objectives:In recent years,excessive drinking has become a social and public issue of great concern throughout the world.Excessive drinking can cause serious harm to the health of the body.It is believed that excessive drinking can cause damp and hot poisonous evil to restrain the spleen and stomach,or damage the liver and gallbladder to cause liver loss and drainage.in traditional Chinese medicine.Jinzhao Capsule is a product that Infinitus has listed.It is composed of Radix Puerariae,Semen Hoveniae,Gardenia Jasminoide and has the function of protecting liver damage and can treat and prevent liver diseases.This experiment mainly explores the advantages of its products,explores its protective mechanism against alcoholic liver and stomach injury,and enhances the scientific and technological content.This experiment first studied the effects of Jinzhao Capsules on the drunkenness,liver function,liver lipids and ethanol metabolizing enzymes,liver and stomach antioxidant enzymes in mice with acute alcoholic liver and stomach injury models.The protective effect mechanism of Jinzhao Capsule on acute alcoholic liver and stomach injury were preliminary discussed,and the experimental basis for its clinical application was provided.Secondly,to study the effects of Jinzhao Capsule on liver function,liver lipid and ethanol metabolism enzymes,antioxidant enzymes,inflammatory factors,Keap1-Nrf2-NF-κB pathway and other indicators in chronic alcoholic liver injury model mice,and to explore Jinzhao Capsule on chronic alcohol Protective effects of liver injury and its mechanism of action.Material and Methods:Experiment 1:Protective effect mechanism of Jinzhao capsules on mice with acute alcoholic liver injurySPF male ICR mice,aged 8 to 10

alcoholic liver injury.Its mechanism of action is related to enhancing the activities of key enzymes and antioxidant enzymes in ethanol metabolism in liver tissues,reducing the production of lipid peroxides,protecting the integrity of liver cell membranes,and reducing the release of transaminase.2 Jinzhao Capsule has the effect of protecting acute alcoholic gastric injury.Its mechanism is related to enhancing gastric antioxidant enzyme activity and protecting gastric mucosal injury.3 Jinzhao Capsule which has the effect of protecting chronic alcoholic liver injury is related to enhancing the activity of key enzymes of ethanol metabolism in the liver tissue of the body,reducing the production of lipid peroxides,and reducing the release of transaminase.4 The mechanism of Jinzhao Capsule to protect chronic alcoholic liver injury is related to enhancing the activity of antioxidant enzymes in the liver tissue,protecting the integrity of liver cell membrane,regulating the level of inflammatory factors,and regulating the keap1/Nrf2/NF-κB pathway mRNA and index protein expression levels. |
