BACKGROUND Donor lymphocyte infusion (DLI) was used as salvage therapy in leukemia relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT), but existing results on DLI administration to acute leukemia patients were disappointing. Although increasing minimal residual disease (MRD) after HSCT had been proven to be highly indicative of(More)
Two series of novel 2,4-diphenyl-1,3-oxazolines containing an oxime ether moiety were designed and synthesized via the key intermediate N-(2-chloro-1-(p-tolyl)ethyl)-2,6-difluorobenzamide. The bioassay results showed that the target compounds with an oxime ether substituent at the para position of 4-phenyl exhibited excellent acaricidal activity against(More)
Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of non-Hodgkin's lymphoma (NHL) in adults, and approximately 50% of cases of DLBCL occur in patients above the age of 60. Although RCHOP regimen was established as the standard therapy for DLBCL patients, there are still a large number of DLBCL patients who can't bear the toxicity of(More)
To evaluat the efficacy and safety of myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) combined with imatinib for advanced chronic myeloid leukemia (CML), 15 patients with accelerated phase (n=6) or blast crisis (n=9) were enrolled in this study. All the patients were conditioned with cyclophosphamide and busulfan, and treated(More)
Chronic myeloid leukemia (CML) is a blood cell cancer with increased proliferation of granulocytes. Signal transducers and activators of transcription 3 (STAT3) is an important regulator of CML. To investigate the possible downstream factors of STAT3 and gain more insight into CML-related pathways, this study focused on the superior cervical ganglia protein(More)
BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a rare clinical syndrome characterized by an infrequent but immune-mediated life-threatening disease, with confusing clinical manifestations, rapidly deteriorating health, high morbidity and mortality and challenging diagnosis. METHODS To improve the recognition and understanding of this disease, we(More)
BACKGROUND Although high mortality in patients with acute leukemia (AL) is associated with intracranial hemorrhage (ICH), the clinical features and pathogenesis of AL patients with cerebral hemorrhage are not well known. METHODS We diagnosed 90 patients with ICH from a total of 1467 patients with non-promyelocytic AL who had been hospitalized in the First(More)
Acute graft versus host disease (aGVHD) remains a major problem after allogeneic hematopoietic stem cell transplantation. Standard frontline therapy for aGVHD involves corticosteroids. However, fewer than half of patients have a lasting complete response. The long-term mortality rate of steroid-refractory aGVHD (SR-aGVHD) remains around 70%. To date, no(More)
A collective asymmetric synthesis of phenanthroindolizidine and phenanthroquinolizidine alkaloids (-)-antofine, (-)-cryptopleurine, (-)-tylophorine, and (-)-tylocrebrine was achieved by means of a reaction sequence involving efficient generation of chiral homoallylic amine intermediates by asymmetric allylation of the corresponding tert-butanesulfinyl(More)
Peripheral blood stem cell (PBSC) collection has been increasingly more popular than bone marrow donation, but little side effects induced by hemogram variation of donors for PBSC collection were reported. The peripheral blood cells were counted pre- and post-collection of PBSC from 166 allogeneic-related donors. Donors' hemoglobin concentration decreased(More)
