The purpose of this study was to detect the distribution of Treg and Th17 cells in bone marrow and to investigate the relationship of Treg/Th17 imbalance with the pathogenesis and progression of multiple myeloma (MM). The Bone marrow was collected from 37 MM patients and 12 healthy volunteers, the ratio of Treg and Th17 cells was detected by flow cytometry. The expression of Treg and Th17 cells simultaneously was examined in peripheral blood of 19 MM patients with same method. The results indicated that the frequency of Treg cells was higher in MM patients than that in control group (P < 0.05), there was a trend of increasing of Treg cell number in the ISS stage from I+II to III (P < 0.05). Furthermore, in the patients with MM, the Treg cell number in bone marrow was higher than that in peripheral blood (P < 0.05). Th17 cell rate was not statistically different between MM patients and control group (P > 0.05), and at different ISS stage (P > 0.05). Th17 cell number between bone marrow and peripheral blood was not significantly different (P > 0.05).The ratio of Treg/Th17 in patients with MM was higher than that in control group (P < 0.05), and increased gradually from ISS stage I+II to stage III (P < 0.05). It is concluded that the Treg/Th17 immune imbalance is presenced in bone marrow of patients with MM, this imbalance may promote the progression of MM.

A wealth of research focused on African American populations has connected rs2814778-CC ("Duffy-null") to decreased neutrophil (neutropenia) and leukocyte counts (leukopenia). While it has been proposed that this variant is benign, prior studies have shown that the misinterpretation of Duffy-null associated neutropenia and leukopenia can lead to unnecessary bone marrow biopsies, inequities in cytotoxic and chemotherapeutic treatment courses, under-enrollment in clinical trials, and other disparities. To investigate the phenotypic correlates of Duffy-null status, we conducted a phenome-wide association study (PheWAS) across more than 1,400 clinical conditions in All of Us, the Vanderbilt University Medical Center's Biobank, and the Million Veteran Program.

Background: Autologous osteochondral transplantation (AOT) is an option to treat large osteochondral lesions of the talus (OLTs), accompanying subchondral cyst, and previous unsuccessful bone marrow stimulation (BMS) procedures. Although there is extensive literature on the outcomes of surgical interventions for medial osteochondral lesions, research focusing on lateral lesions remains limited. This article presents the intermediate-term clinical and radiologic outcomes following AOT for lateral OLTs.

Objectives: To investigate the clinical characteristics and prognosis of acute erythroleukemia (AEL) in children.
Methods: A retrospective analysis was conducted on the clinical data, treatment, and prognosis of 8 children with AEL treated at the First Affiliated Hospital of Zhengzhou University from January 2013 to December 2023.
Results: Among the 7 patients with complete bone marrow morphological analysis, 4 exhibited trilineage dysplasia, with a 100% incidence of erythroid dysplasia (7/7), a 71% incidence of myeloid dysplasia (5/7), and a 57% incidence of megakaryocytic dysplasia (4/7).

Background: The prognosis of a plasma cell neoplasm (PCN) varies depending on the presence of genetic abnormalities. However, detecting sensitive genetic mutations poses challenges due to the heterogeneous nature of the cell population in bone marrow aspiration. The established gold standard for cell sorting is fluorescence-activated cell sorting (FACS), which is associated with lengthy processing times, substantial cell quantities, and expensive equipment.
