Brief summary: According to the 2022 ELN guidelines patients with high-risk acute myeloid leukemia were randomly divided into MA-BUCY2 conditioning group and BuCy2 conditioning group，to evaluate the efficacy and safety of two conditioning regimens in haploidentical hematopoietic stem cell transplantation.

Detailed description: High risk acute myeloid leukemia patients were randomly divided into two groups before conditioning of haploidentical hematopoietic stem cell transplantation.The control group will use the BUCY2 conditioning，and the experimental group will use mitoxantrone liposome combined with BUCY2 for conditioning. After transplantation，we will observe the difference of one year relapse rates between two goups，also the adverse reactions of conditioning，GVHD，OS and PFS of the patients in two groups also been observed.

  5. Cardiac ejection fraction (LVEF) is less than 60%;
  6. History of myocardial infarction, unstable angina pectoris, severe unstable ventricular arrhythmia or He has any arrhythmia requiring treatment, clinical history of serious pericardial disease, or acute ischemia or activity ECG evidence of abnormal conduction system.;\\
