Inclusion Criteria:
1. Patients with confirmed CEBPA mutant AML. Diagnostic criteria include the presence of CEBPA mutant gene detected at the molecular level;
2. Patients with high-risk molecular markers or gene mutations, or complex karyotypes for disease recurrence, or flow cytometry/gene MRD positivity after two chemotherapy treatments; high-risk molecular markers or gene mutations include: CD7 positive, WT1 mutation, non-bzip-inframe CEBPA mutation; The positive threshold for flow cytometry MRD was 0.0001%; The MRD threshold of molecular biology is the lowest value of the detection protocol of the center.
3. Medical history and diagnosis of MICM, exclusion of MDS, transformation and treatment-related AML;
4. Age 18-65 years old (18 years old ≤Age\< 65 years old);
5. Liver and kidney function: blood bilirubin ≤ 35 μmol/L, AST/ALT below 2 times the upper limit of normal, serum creatinine ≤ 150 μmol/L;
6. Normal cardiac function (EF≥50%, New York Cardiac Function Classification NYHA I/II);
7. Physical condition score 0-2 (ECOG score);
8. For patients with peripheral blood leukocytes \< 50\*109/L at the initial onset, no chemotherapy has been given except for hydroxyurea before the start of induction therapy;
9. For patients with peripheral blood leukocytes ≥ 50\*109/L at the initial onset, cytarabine and hydroxyurea are allowed to be treated before the start of induction therapy;
10. Non-pregnant and lactating women;
11. For all women of childbearing age, a pregnancy test must be performed to measure hCG to rule out pregnancy;
12. Obtain informed consent signed by the patient or family member.
Exclusion Criteria:
1. MDS-converted AML, treatment-related AML; mixed cell leukemia; AML patients with central nervous system infiltrates and extramedullary lesions at the time of onset;
2. Relapse patients;
3. Allergies or contraindications to any of the drugs involved in the protocol;
4. Liver and kidney function are obviously abnormal, exceeding the enrollment criteria;
5. Cardiac disease: including echocardiogram EF \<50%, cardiac insufficiency (New York cardiac function classification NYHA: III/IV), pericardial effusion (CTCAE score \>2) within six months after acute myocardial infarction, ECG QTc \>470ms;
6. Lung diseases: pulmonary edema, pleural effusion (CTCAE score \>2);
7. Suffering from malignant tumors of other organs at the same time;
8. Active patients with HAV, HBV, HCV and tuberculosis, HIV-positive patients;
9. Concomitant other hematologic diseases (including coagulation abnormalities unrelated to leukemia);
10. Inability to understand or follow the study protocol;
11. Those who participate in other clinical studies at the same time; Presence of any other condition that would preclude the conduct of the study
