2. Currently receiving (or within the past 90 days) chronic or intermittent hemodialysis or peritoneal dialysis.

   Liver Disease:

3. Clinically or histologically confirmed liver cirrhosis (Fibrosis Stage 4).

4. History of hepatic decompensation (e.g., ascites, hepatic encephalopathy, or variceal bleeding).

5. Presence of the following acute or chronic liver diseases at screening: autoimmune hepatitis, primary biliary cholangitis, alcoholic liver disease, Wilson's disease, or drug-induced liver injury.

   Gastrointestinal Disease:

6. History of gastric bypass surgery.

7. History of peptic or gastrointestinal ulcer within 12 months prior to randomization.

8. History of clinically active inflammatory bowel disease within 12 months prior to randomization.

   Cardiovascular Disease:

10. History of myocardial infarction, stroke, uncontrolled arrhythmia, unstable angina, coronary artery bypass grafting, or percutaneous coronary intervention within 6 months prior to screening.

11. Current or previous history of New York Heart Association (NYHA) Class IV congestive heart failure.

12. Planned coronary, carotid, or peripheral arterial revascularization.

13. Uncontrolled hypertension despite antihypertensive therapy, defined as sustained SBP >150 mmHg and/or DBP >100 mmHg.

    Hematologic Disease:

14. Hematologic disorders or any condition causing hemolysis or red blood cell instability at screening, including but not limited to: glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, hemolytic anemia, iron deficiency anemia, aplastic anemia, chronic malaria, splenectomy, reticulocytopenia.

    Oncology:

15. History of or current malignancy within the past 2 years, except for basal cell carcinoma or excised non-invasive squamous cell carcinoma of the skin.

16. Current, planned, or anticipated treatment with radiotherapy, cytotoxic chemotherapy, or immunomodulators (e.g., interleukins, interferons). Long-term stable use of immunosuppressants is permitted if approved by the investigator.

    Diagnostic Assessments:

17. Clinically significant laboratory abnormalities or ECG changes at screening, including but not limited to:

    1. Platelet count <150,000/mm³.
    2. International Normalized Ratio (INR) >1.3.
    3. Alkaline Phosphatase (ALP) >2 × Upper Limit of Normal (ULN).
    4. Total bilirubin >1.3 × ULN, unless the subject has Gilbert's syndrome.
    5. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥5 × ULN.
    6. Corrected QT interval (QTc) >450 ms for males or >470 ms for females (Fridericia's formula).

18. Active severe infection requiring parenteral antibiotic or antifungal therapy within 30 days prior to or at screening.

19. Evidence of the following viral infections at screening:

    1. Human Immunodeficiency Virus (HIV) infection: defined as positive HIV antibody.
    2. Syphilis infection: defined as positive Treponema pallidum antibody (TP-Ab).
    3. Active Hepatitis B Virus (HBV) infection: defined as positive Hepatitis B surface antigen (HBsAg) OR positive Hepatitis B core antibody (HBcAb) with HBV-DNA >500 IU/mL or >2000 copies/mL.
    4. Active Hepatitis C Virus (HCV) infection: defined as positive HCV antibody (HCV-Ab) with HCV-RNA above the ULN.

    Other:

20. Major surgery within 30 days prior to screening.

21. History of solid organ transplantation or being on a waiting list for such transplantation.

22. Blood donation or blood loss ≥400 mL within 3 months prior to screening, or anticipated need for blood transfusion within 12 weeks after randomization.

23. Known exposure to UDCA（Ursodeoxycholic Acid） or BBR（Berberine） within 3 months prior to screening, or known allergy to UDCA or BBR.

24. History or evidence of Type 1 diabetes.

25. Female subjects who are pregnant, breastfeeding, planning pregnancy, or of childbearing potential and not using highly effective contraception.

26. Participation in any clinical study of an approved or investigational product within 30 days prior to screening.

27. Any condition that, in the investigator's judgment, may jeopardize the subject's safety or compliance with the study protocol.
