Eligibility
Inclusion criteria
Inclusion criteria: 1. Age>=18 years old, male or female; 2. Patients with clinically confirmed chronic liver disease acquired hypofibrinogenemia, defined as meeting both of the following 2 criteria: a) Clinically diagnosed chronic liver disease, including viral hepatitis, alcoholic liver disease, non-alcoholic fatty liver disease, autoimmune liver disease, etc.; b) Patients with acute bleeding and functional fibrinogen level <=150 mg/dL; or patients who are scheduled for elective surgery (including traumatic or invasive procedures such as deep venipuncture, liver puncture, abdominal puncture, etc.) with a functional fibrinogen level of <=120 mg/dL 3. All subjects of childbearing potential must use effective contraception after entering the screening period until 3 months after the completion of the study; 4. Subjects give voluntary informed consent and sign the informed consent form.
Exclusion criteria
Exclusion criteria: Subjects who meet any of the following criteria will not be eligible to participate in this clinical trial: 1.
