13. for other reasons, researchers believe that it is not suitable for inclusion; if a subject with liver function impairment meets any of the following exclusion criteria, they need to be excluded: 14. the subject has any of the following conditions: drug-induced liver injury; history of liver transplantation; cirrhotic patients with liver failure, hepatic encephalopathy, hepatocellular carcinoma (excluding those with barcelona stage 0 or curative treatment), hepatorenal syndrome, esophageal and gastric variceal bleeding and other complications deemed inappropriate by researchers;
