Objective To analyze the diagnostic efficacy of aspartate aminotransferase（AST）,cholinesterase（CHE）,carbohydrate antigen 125（CA125）,and alpha fetoprotein（AFP）in patients with liver cirrhosis．Methods A total of 70 patients with liver cirrhosis were included in the observation group as the study subjects,and 70 healthy individuals who underwent physical examinations during the same period were selected as the control group．Both groups of research subjects underwent biochemical testing and tumor marker testing．The AST,CHE,CA125,and AFP detection results of two groups of research subjects were compared,and the diagnostic effect of the above indicators on patients with liver cirrhosis were analyzed．Results The CHE test results of patients with liver cirrhosis in the observation group were significantly lower than those of healthy individuals undergoing physical examination,and the AST,CA125,and AFP test results were higher（P<0.05）．AST and CHE had good sensitivity and specificity in the diagnosis of liver cirrhosis．The sensitivity,specificity and coincidence rate of CA125 combined with AFP were higher than those of CA125 or AFP alone．Conclusions AST,CHE,CA125,and AFP have good clinical application performance in the diagnosis of liver cirrhosis patients,and are important reference indicators reflecting the progression of liver cirrhosis in patients．
