A novel regimen, which is composed of a low dose of ATG (5 mg/kg) and low-dose PTCy (one dose of PTCy, 50mg/kg) for GvHD prophylaxis in Haplo-PBSCT for patients with hematologic malignancies, was designed to decrease the risk of aGvHD and lower the incidence of virus reactivation.

Diagnosis was according to the criteria of 2008 World Health Organization (WHO) classification of myeloid tumors. 2. Family members selected as donors were typed at the HLA-A, -B, -DQB1, -C and -DRB1 locus at high-resolution level. Haplotype was defined as recipient-donor number of HLA mismatches \> 3. 3.14 to 70 years old. 4.Performance status scores no more than 2 (ECOG criteria). 5.Adequate organ function as defined by the following criteria: alanine transaminase （ALT）, aspartate transaminase（AST） and total serum bilirubin \<2×ULN (upper limit of normal). Serum creatinine and blood urea nitrogen (BUN) \<1.25×ULN. 6.Adequate cardiac function without acute myocardial infarction, arrhythmia or atrioventricular block, heart failure, active rheumatic heart disease and cardiac dilatation(the patients has been improved after treatment of the disease and are not expected to affect transplant can include in the study). 7.Absence of any other contraindications of stem cell transplantation.

Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures. Exclusion Criteria: 1. DSA strong positive (titer \>10000MFI) 2. Life expectancy \< 3 months because of other severe diseases. 3. Presence of any fatal disease, including respiratory failure, heart failure, liver or kidney function failure. 4. Uncontrolled infection. 5. Pregnancy or breastfeeding. 6. Has enrolled in another clinical trials. 7.
