Inclusion Criteria:
1\. Men and women aged between 18 and 80 years (inclusive) who understand and sign informed consent forms; 2. Compensated MASLD-related cirrhosis diagnosis(meet one of the following conditions):
1. The liver biopsy during the screening period (liver biopsy within 6 months of screening is acceptable) showing cirrhosis with steatohepatitis according to the Non Alcoholic Fatty Liver Disease Clinical Research Network (NASH-CRN) scoring system, and there is no evidence of competitive aetiology.
2. The liver biopsy during the screening period (liver biopsy within 6 months of screening is acceptable) showing cirrhosis with steatosis (no steatohepatitis) according to NASH-CRN scoring system, and there is no evidence of competitive aetiology. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including overweight/obesity and/or prediabetes/type 2 diabetes mellitus (T2DM).
3. Historical biopsy showed steatohepatitis, and now diagnosed with cirrhosis through non-invasive tests or clinical criteria (see criterion (6)-1)). There is no evidence of competing aetiology. There is at least 1 coexisting or history of metabolic comorbidity.
4. Historical biopsy showed steatosis (no steatohepatitis), and now diagnosed with cirrhosis through non-invasive tests or clinical criteria (see criterion (6)-1)). There is no evidence of competing aetiology. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including overweight/obesity and/or prediabetes/type 2 diabetes mellitus (T2DM).
5. 'Cryptogenic cirrhosis' (with no evidence of hepatic steatosis on both histopathology and imaging). There is no evidence of competing aetiology. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including overweight/obesity and/or prediabetes/type 2 diabetes mellitus (T2DM).
6. MASLD-related cirrhosis is defined based on the following criterias:
a. Cirrhosis is defined based on one of the following non-invasive tests(NITS): i: MRE ≥ 5kPa or VCTE-LSM ≥ 20kPa; ii:VCTE ≥15 kPa and \<20 kPa and 1 of the following: MRE≥4.2kPa or Agile4≥0.565 or Platelets≤150,000/µL; iii: VCTE \<15 kPa and 2 of the following: MRE≥4.2kPa or Agile4≥0.565 or Platelets≤150,000/µL; b. Current or previous imaging examinations have diagnosed fatty liver or controlled attenuation parameter (CAP)≥288dB/m or magnetic resonance imaging proton density fat fraction (MRI-PDFF)≥5%.
c. There is no evidence of competing aetiology; d. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including overweight/obesity and/or prediabetes/type 2 diabetes mellitus (T2DM).
Exclusion Criteria:
* 1\. Other chronic liver diseases (including but not limited to viral hepatitis, alcoholic liver disease, drug-induced liver injury, autoimmune liver disease, Wilson's disease, hemochromatosis, etc.) 2. There has been a continuous history of heavy drinking for 3 months or more current or rencent 5 years (heavy drinking is defined as \>20 g/day in women and \>30 g/day in men); Or researchers can not reliably quantify alcohol consumption.
3\. Hepatic decompensation events (including ascites, esophageal and gastric variceal bleeding, hepatic encephalopathy, hepatorenal syndrome, spontaneous bacterial peritonitis, etc.) or hepatocellular carcinomaor.
4\. Previous (\<5 years before screening) treatment for obesity with surgery; 5. Have obesity induced by other endocrinologic disorders (i.e. Cushing Syndrome) genetic diseases; 6. Secondary factors that can cause liver steatosis, such as malnutrition, medication, genetic metabolic diseases, etc.
7\. Positive for human immunodeficiency virus (HIV) infection; 8. History of drug use or abuse of drugs within the 12 months prior to screening.
9\. Pregnant or lactating women; 10. Researchers believe that patients who are not suitable to participate in this study.
