Inclusion criteria
* Patients willing to sign informed consent * Patients aged 18-65 * According to the diagnosis standard of liver failure in the guide for diagnosis and treatment of liver failure (2018 Edition), the eligible patients are included, that is, on the basis of chronic liver disease, the syndrome with acute jaundice deepening and coagulation dysfunction as the manifestation of liver failure caused by various inducements can be combined with complications such as Hepatoencephalopathy, ascites, electrolyte disorder, infection, hepatorenal syndrome, hepatopulmonary syndrome, etc And extrahepatic organ failure. The patient's jaundice deepened rapidly, the serum TBIL ≥ 10 × ULN or the daily rise ≥ 17.1 μ mol / L; there was bleeding, PTA ≤ 40% (or INR ≥ 1.5)
Exclusion criteria
* Patients with severe heart failure, COPD, cerebrovascular accident, nephrotic syndrome, etc; * Patients with gastrointestinal bleeding, pulmonary infection, septicemia, etc * Patients with liver cancer, lung cancer, lymphoma and other malignant tumors * Patients taking anticoagulants, mental diseases and immune diseases for a long time * Pregnant or lactating women.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| gut microbiota change | Fecal samples were collected 1 week before faecal bacteria transplantation, and change from at 5 day, 10 day, 15 day, 20 day, 4 and 8 weeks after faecal bacteria transplantation, respectively | Gene sequencing and metabonomics analysis of fecal flora. |
| Observe the clinical manifestations, safety and adverse reactions of the patients | These indicators were collected 1 week before faecal bacteria transplantation, and change from at 5 day, 10 day, 15 day, 20 day, 4 and 8 weeks after faecal bacteria transplantation, respectively | Safety and adverse events were assessed including fever, diarrhea and elevated inflammatory markers (such as C-reactive protein and procalcitonin) before and after faecal bacteria transplantation. |
| Liver function change | Blood samples were collected 1 week before faecal bacteria transplantation, and followed up at 5 day, 10 day, 15 day, 20 day, 4 and 8 weeks after faecal bacteria transplantation, respectively | The investigators need to monitor the changes in liver and kidney function before and after faecal bacteria transplantation，such as ALT、AST、GGT 、TBIL(The units of these indices are U/L). |
| Coagulation function change | Blood samples were collected 1 week before faecal bacteria transplantation, and followed up at 5 day, 10 day, 15 day, 20 day, 4 and 8 weeks after faecal bacteria transplantation, respectively | Prothrombin activity are one of the indexes to evaluate the degree of liver failure in patients.The units of this indices is %. |
| Model for end-stage liver disease score change | Model for end-stage liver disease score were obtained separately in 1 week before faecal bacteria transplantation, and to access once again at 5 day, 10 day, 15 day, 20 day, 4 and 8 weeks after faecal bacteria transplantation, respectively | The model for end-stage liver disease (MELD) score is a prospectively developed and validated scale for the severity of end-stage liver disease.The higher the MELD score, the more severe the liver disease and the greater the risk of death. The fatality rate of patients with MELD between 20 and 30 was more than 30%, that of patients with MELD between 30 and 40 was more than 50%, and that of patients with MELD \>40 was more than 70%. |
| proinflammatory cytokine change | Blood samples were collected 1 week before faecal bacteria transplantation, and followed up at 5 day, 10 day, 15 day, 20 day, 4 and 8 weeks after faecal bacteria transplantation, respectively | IL-17,IL-6,TNF-α, TGF-β, IFN-γ and other cytokines were detected by ELISA(The units of these indices are pg/mL). |
