The indexes of azelotransferase, alanine aminotransferase, glutamyltransferase, total bilirubin, plasminogen time and the mean volume of erythrocytes are elevated, and they may be decreased after alcohol abstinence. 4. Liver ultrasonography or CT examination has typical manifestations. 5. Exclude hepatophiles. Typical manifestations of liver ultrasound or CT examination. 5. Rule out hepatophilic virus infection, drugs and toxic liver injury, etc. Alcohol conversion formula: g=drinking volume (ml)×alcohol content (%)×0.8 Therapeutic countermeasures for alcoholic liver disease. 1. Abstinence from alcohol and nutritional support. 2. Control of high metabolic state, inflammation, cytokine dysregulation, oxygen stress. 3. Symptomatic treatment of alcoholic cirrhosis and its complications. 4. Abstinence from alcohol in liver transplant. 1.
