数据说明

Conditions: Atypical Chronic Myeloid Leukemia, BCR-ABL1 Negative, Chronic Myelomonocytic Leukemia, de Novo Myelodysplastic Syndrome, Essential Thrombocythemia, Myeloproliferative Neoplasm, Paroxysmal Nocturnal Hemoglobinuria, Polycythemia Vera, Polycythemia Vera, Post-Polycythemic Myelofibrosis Phase. PRIMARY OBJECTIVES: I. Decrease the incidence of day-200 hematopoietic cell transplantation (HCT) failure to < 20% in patients with MDS-Refractory anemia (RA)-(ringed sideroblasts [RS])/MPD and in patients with chronic myelomonocytic leukemia (CMML)/refractory anemia with excess blasts (RAEB). SECONDARY OBJECTIVES: I. The rate of relapse/progression in patients with MPD or MDS-RA and those with CMML or MDS-RAEB. II. The probability of progression free survival (PFS) in patients with MPD or MDS-RA and those with CMML or MDS-RAEB. III. The kinetics of donor engraftment. IV. The incidence of infections. OUTLINE: This is a dose-escalation study of total body irradiation (TBI). NONMYELOABLATIVE CONDITIONING REGIMEN: Patients receive fludarabine phosphate intravenously (IV) on days -4 to -2 and undergo TBI on day 0. PERIPHERAL BLOOD STEM CELL (PBSC) TRANSPLANTATION: Patients undergo filgrastim (G-CSF)-mobilized PBSC infusion after TBI on day 0. IMMUNOSUPPRESSION: Matched Related Donor: Patients receive cyclosporine orally (PO) twice daily (BID) on days -3 to 56, followed by a taper until day 180. Patients also receive mycophenolate mofetil (MMF) PO BID beginning 4-6 hours after transplantation on day 0 and continue until day 27. Unrelated Donor: Patients receive cyclosporine PO BID on days -3 to 100, followed by a taper until day 180. Patients also receive MMF PO three times daily beginning 4-6 hours after transplantation on day 0 and continue until day 40, followed by a taper until day 96. After completion of study treatment, patients are followed periodically.

数据加载示例（图像类）

from PIL import Image
import glob, os

files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.tif"), recursive=True))
print("图像文件数:", len(files))
img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)

# torchvision Dataset 方式:
# from torchvision import datasets
# ds = datasets.ImageFolder(path)  # 要求 子目录=类别
