• Expected survival ≥ 12 weeks.

• Subjects of HBsAg (-) and HBcAb (-) were admitted into the group;If HBsAg (+) or HBcAb (+), hbv-dna must be ≤ 500 IU/mL to be included in the group, and those with elevated hbv-dna must agree to receive nucleoside anti-hepatitis b virus treatment.Subjects with negative HCV antibody (-) or hcv-rna were admitted.If hcv-rna is positive, subjects must have ALT and AST ≤ 3×ULN to be enrolled.Subjects with co-infection of hepatitis b and c should be excluded.
