Objective: To investigate the effects of bortezomib(BTZ) and thalidomide(TM) on peripheral blood memory T-cells (T) and regulatory T cells(Tregs) in patients with multiple myeloma(MM).
Methods: Eighty-six MM patients received 2 courses of chemotherapy were divided into effective (partial response at least) group (63 cases) and ineffective (no partial response) group (17 cases) according to therapeutic efficacy; these 80 patients were divided into BTZ group (38 cases) and TM group (42 cases) yet according to therapeutic regimens, 20 newly diagnosed MM patients were used as baseline group, 30 healthy volunteers were used as healthy control group. The T subsets and Treg in peripheral blood of each groups were detected by flow cytometry.
Results: The CD4 central memory T cells (CD4 T) percentage of CD4 T, the CD18 T percentage of CD18T and ratio of CD8 T and CD8 effector memory T cells (T) (CD8 T/T) in baseline group were all significantly lower than those in healthy control group (P<0.05). After treatment with BTZ regimen or TM regimen, the CD8T percentage of CD8 T in effective group significantly increased to level of healthy control group (P<0.05); the Treg cell level in effective and in effective groups was not significantly different from that in baseline group(P>0.05), but the Treg percentage of CD4 cells ineffective group was significantly higher than that in baseline group and ineffective group (P<0.05). According to ROC curve, the critical value of CD8T/T for predicting chemotherapeutic response was 0.27 with sensitivity of 57.1% and specificity of 94.1%.
Conclusion: When MM patients are in an immuno-exhanstive status, the treatment with BTZ or TM both can reverse the immuno-inhibitory status of MM patients, moreover, does not affect the Treg cell count; the Treg percentage in BTZ and TM effective groups both are significantly higher than that in baseline group and ineffective group. The ratio of CD8T/T contributes to evaluating the chemotherapeutic efficacy.

High degree of variability in human leukocyte antigens (HLAs) system restricts availability of histocompatible HLA-matched-related donors, thus increasing reliance on worldwide bone marrow registries network. Nevertheless, due to limited coverage/accessibility/affordability of some ethnicities in these registries, haploidentical haematopoietic stem cell transplantation (HSCT) emerged as an alternative option, though with allorecognition-mediated graft versus host disease (GvHD) (>40% cases). A dimorphism [-21 methionine (M) or threonine (T)] in HLA-B leader peptide (exon 1) which differentially influences its HLA-E binding, plausibly regulates natural killer cell functionality, affecting GvHD vulnerability and clinically in practice for donor selection.

Introduction: Introduction The Hy antigen is one of ten red cell antigens belonging to the Dombrock blood group system, with an antigen frequency of almost 100% in the majority of populations. Alloantibodies to high prevalence antigens cause difficulties with antibody identification and exclusion in serological investigations.
Case Presentation: This review describes the management of four antenatal cases where the presence of alloanti-Hy had been identified.

Inherited retinal diseases (IRDs) constitute a heterogeneous group of clinically and genetically diverse conditions, standing as a primary cause of visual impairment among individuals aged 15-45, with an estimated incidence of 1:2000. Our study aimed to comprehensively evaluate the genetic variants underlying IRDs in the Turkish population. This study included 50 unrelated Turkish IRD patients and their families.

Background: Recent studies have emphasized the association between prolonged screen exposure and neurodevelopmental disorders, though its correlation with tic disorders (TDs) remains ambiguous. We thus conducted this study to investigate the association between screen time (ST) and the severity of tic symptoms in children diagnosed with TDs.
Methods: We conducted a retrospective case-control study with 342 cases of TDs and 270 controls, collecting data from March 2021 to December 2023.
