Article Synopsis
  • The study investigates the transition from acute kidney injury to chronic kidney disease, emphasizing the challenge in current animal models that require severe injury to initiate renal fibrosis.
  • Researchers developed a new method using a gradient approach to induce ischemia/reperfusion (I/R) injury in mice while keeping kidney function relatively stable.
  • The findings revealed that while short-term kidney damage was apparent, only the lower kidney pole showed persistent damage leading to renal fibrosis, highlighting the model's ability to demonstrate "silent" fibrosis over time.

Objectives: To investigate the effect of dexamethasone (DXM) on acute lung and kidney injury with sepsis and its possible mechanism.

Methods: Control (NC), lipopolysaccharide (LPS) and lipopolysaccharide + dexamethasone (LPS+DXM) treated groups were established by random assignment of 72 Wistar rats. The NC rats were injected with physiological saline, while the LPS group was injected with LPS (5 mg/kg) and LPS+DXM group was injected with LPS(5 mg/kg) first and followed by DXM (1 mg/kg).

Background: Erythropoiesis-stimulating agents (ESAs) have played an important role in the treatment of renal anemia in children, but cannot improve hemoglobin to target level in some cases. Roxadustat, a hypoxia-inducible factor prolyl hydroxylase inhibitor, can stimulate endogenous erythropoietin production and regulate iron metabolism even in patients with kidney failure. However, roxadustat has not yet been approved for use in children.

Mesenchymal stem cells (MSCs) have already demonstrated definitive evidence of their clinical benefits in acute graft-versus-host disease (aGvHD) and other inflammatory diseases. However, the comprehensive mechanism of MSCs' immunomodulation properties has not been elucidated. To reveal their potential immunosuppressive molecules, we used RNA sequencing to analyze gene expression in different tissue-derived MSCs, including human bone marrow, umbilical cord, amniotic membrane, and placenta, and found that chitinase-3-like protein 1 (Chi3l1) was highly expressed in human umbilical cord mesenchymal stem cells (hUC-MSCs).

Myelodysplastic syndromes (MDS) are generally considered as a group of clonal diseases derived from hematopoietic stem cells, but a number of studies have suggested that they are derived from myeloid progenitor cells. We aimed to identify the cell of origin in MDS by single-cell analyses. Targeted single-cell RNA sequencing, covering six frequently mutated genes (U2AF1, SF3B1, TET2, ASXL1, TP53, and DNMT3A) in MDS, was developed and performed on individual cells isolated from the CD34 and six lineage populations in the bone marrow of healthy donors (HDs) and patients with MDS.

Little is known regarding whether the cell of origin differs among different leukemia types. To address this fundamental issue, we determined the cell of origin in five distinct types of acute leukemia induced by N-Myc overexpression in mice. CD150CD48CD41CD34c-KitSca-1Lin (KSL) (HSC1) cells, CD150CD48CD41CD34KSL (HSC2) cells, CD150CD41CD34KSL (HPC1) cells, CD150CD41CD34KSL (HPC2) cells, and CD150CD41CD34KSL (HPC3) cells were purified from the bone marrow of adult C57BL/6 mice, transduced with the N-Myc retrovirus vector, and transplanted into lethally irradiated mice.

Radioprotection was previously considered as a function of hematopoietic stem cells (HSCs). However, recent studies have reported its activity in hematopoietic progenitor cells (HPCs). To address this issue, we compared the radioprotection activity in 2 subsets of HSCs (nHSC1 and 2 populations) and 4 subsets of HPCs (nHPC1-4 populations) of the mouse bone marrow, in relation to their in vitro and in vivo colony-forming activity.

Background: Pathogenic variants of PAX2 cause autosomal-dominant PAX2-related disorder, which includes variable phenotypes ranging from renal coloboma syndrome (RCS), congenital anomalies of the kidney and urinary tract (CAKUT) to nephrosis. Phenotypic variability makes it difficult to define the phenotypic spectrum associated with genotype.

Methods: We collected the phenotypes in patients enrolled in the China national multicenter registry who were diagnosed with pathogenic variant in PAX2 and reviewed all published cases with PAX2-related disorders.

Objective: This study explored the feasibility of congenital heart disease (CHD) screening by combining a percutaneous oxygen saturation (POX) test with cardiac auscultation method in neonates.

Methods: POX tests and cardiac auscultation were used concurrently to screen 8305 neonates born in Jinjiang City Hospital between January 2016 and December 2018 for CHD. The positive screening results (positive POX or positive cardiac auscultation) were confirmed with echocardiography, while any false negative results were identified through follow-up and parent feedback.

Objective: This study aimed to evaluate the effects of a structured team nursing model on the efficacy and quality of cardiopulmonary resuscitation (CPR) in acute myocardial infarction patients undergoing percutaneous coronary intervention (PCI).

Methods: With the random number table, 130 myocardial infarction patients undergoing PCI were divided into two groups, including the control group (n=65) receiving routine emergency resuscitation and nursing care, and the study group (n=65) receiving a structured team care model. The efficacy of CPR, cardiac function, exercise tolerance, ability of daily living activities, quality of life, complication rate and nursing satisfaction were compared between the two groups.

The CRISPR/Cas9 system has been used for genome editing of human and mouse cells. In this study, we established a protocol for gene knockout (KO) in mouse hematopoietic stem cells (HSCs). HSCs were highly purified from the bone marrow of tamoxifen-treated Cas9-EGFP/Cre-ER transgenic mice, maintained in serum-free polyvinyl alcohol culture with cytokines, lentivirally transduced with sgRNA-Crimson, and transplanted into lethally irradiated mice with competitor cells.

Flow cytometry has been widely used in basic and clinical research for analysis of a variety of normal and malignant cells. Hematopoietic stem cells (HSCs) and leukemic stem cells (LSCs) can be highly purified by flow cytometry. Isolated HSCs and LSCs can be functionally identified by transplantation assays and can also be studied at the molecular level.

Airway inflammation of eosinophilic asthma (EA) attributes to Th2 response, leaving the role of Th17 response unknown. Signal transducer and activator of transcription 3 (STAT3) induce both suppressors of cytokine signaling 3 (SOCS3) and retinoic acid receptor-related orphan nuclear receptor γ (RORγt) to initiate Th17 cell differentiation which is inhibited by SOCS3, a negative feedback regulator of STAT3. Heme oxygenase-1 (HO-1) is a stress-responsive, cytoprotective, and immunoregulatory molecular.

Hematopoietic stem cells (HSCs) self-renew or differentiate through division. Cytokines are essential for inducing HSC division, but the optimal cytokine combination to control self-renewal of HSC in vitro remains unclear. In this study, we compared the effects of interleukin-12 (IL-12) and thrombopoietin (TPO) in combination with stem cell factor (SCF) on in vitro self-renewal of HSCs.
