The normal range of liver function indexes: ALB 35–55 g/L, AST 15–40 U/L, ALT 9–50 U/L, TBIL 3.4–17.1 µmol/L,GGT 10–60 U/L,ALP 45–125 U/L,PT 10–13 s,INR 0.5–1.2. The types of liver damage: i) hepatocellular: R ≥ 5; ii) cholestatic type: R ≤ 2; iii) mixed type: 2 < R < 5; iv) abnormal liver biochemical examination: abnormal ALT and ALP but unmet the above criteria.
