IL-17 promotes melanoma through TRAF2 as a scaffold protein recruiting PIAS2 and ELAVL1 to induce EPHA5.

An abnormal immune response induces melanoma development. IL-17 and the classical downstream signal STAT1 are associated with melanoma development. TRAF2 also mediates the downstream signaling of IL-17; however, its role in IL-17-stimulated melanoma remains unclear.

Clinical characteristics of pediatric allogeneic hematopoietic stem cell transplantation-associated thrombotic microangiopathy (TA-TMA): a retrospective single-center analysis.

Objectives: To investigate the clinical features of thrombotic microangiopathy associated with allogeneic hematopoietic stem cell transplantation in children.

Methods: A retrospective analysis of continuous clinical data from HSCT received in the Department of Hematology and Oncology of Wuhan Children's Hospital from August 1, 2016 to December 31, 2021.

Results: During this period, 209 patients received allo-HSCT in our department, 20 (9.

[Clinical Analysis of Salvage Treatment of Glucocorticoid Resistant Graft-Versus-Host Disease with Vedolizumab in Children].

Objective: To investigate the efficacy and safety of VDZ (Vedolizumab) in the salvage treatment of glucocorticoid resistance to gastrointestinal graft-versus-host disease (GR-GI GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children.

Methods: The clinical data of 5 patients with refractory GI GVHD who received allo-HSCT in Wuhan Children's Hospital from December 2020 to December 2021 were retrospectively analyzed with VDZ salvage therapy.

Results: Among the 5 children with refractory GI GVHD, there were 1 male and 4 female, including 2 cases of extremely severe aplastic anemia, 1 case of acute myeloid leukemia (M2, high-risk), 1 case of fanconi anemia and 1 case of myelodysplastic syndrome.

[The Relationship between Plasma sST2/Reg3α Levels and Acute Graft-Versus-Host Disease in Children After Allogeneic Hematopoietic Stem Cell Transplantation].

Objective: To explore the relationship between plasma sST2/Reg3α levels and acute graft-versus-host disease (aGVHD) in children after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: The clinical data of 29 pediatric patients received allo-HSCT treatment in Department of Hematology and Oncology of Wuhan Children's Hospital from January 2019 to January 2020 were collected. Peripheral blood samples were collected at 14 and 28 day after allo-HSCT.

[Analysis of causes of death and etiological characteristics of skin tissue donors].

To investigate the causes of death and etiological characteristics of skin tissue donors, and to provide reference for allogeneic skin transplantation. From October 2008 to October 2018, 49 skin tissue donors accepted by the Burn Department of Wuhan Third Hospital met the inclusion criteria of this study, and a cross-sectional study was conducted. According to the cause of death, the donors were divided into accidental death group (19 cases) and non-accidental death group (30 cases).

Association of Helicobacter pylori infection with gastroesophageal reflux disease.

Objective: Many studies have shown that Helicobacter pylori ( Hp) is negatively correlated with gastroesophageal reflux disease (GERD). Moreover, some studies deny that eradication of Hp increases the incidence of GERD. Therefore, we investigated the association of Hp infection with GERD.

Up-regulation of Tim-3 expression contributes to development of burn-induced T cell immune suppression in mice.

T cell immunoglobulin and mucin domain 3 (Tim-3) is well known to negatively regulate T cells responses, but its role in burn-induced T cells immune suppression remains unclear. In the present study, in order to identify the relationship between Tim-3 expression and post-burn T cells immune suppression, C57BL/6 mice were subjected to burn injury or sham injury, and the liver and spleen were harvested at the day 1 after operation. The expression level of Tim-3 on hepatic or splenic T cells and the functional properties of Tim-3(+) T cells were evaluated.
