Abstract: cases of ALD are analyzed clinically. 80 cases of viral posthepatitic cirrhosis are matched controls, we analyze the epidemiology, clinical situation, laboratory test, related factors of AC (alcoholic cirrhosis) and the effect of drug to protect liver after temperance. ALD patients hospitalized are all male, the majority of them is AC. The peak of episode is in the youth and the middle-age (35-55years old) . The infectious rate of hepatitis virus of ALD is 16.44% which is higher than that of the general. There is no completely positive correlation between the occurrence of AC and amount for liquor taken daily and the time limit of drinking. The infection of hepatitis virus aggravates the liver lesion of AC and is the risk factor for AC develope to hepatocarcinoma. The clinical situation of ALD has no specificity, but liver tumefaction is more common in AC than in viral posthepatitic cirrhosis. The serum levels of enzyme (AST、ALT、GGT) are above normality, and the step-up of GGT take advantage. After temperance, the effect of drug to protect liver in AC is better than in viral posthepatitic cirrhosis.
