[Value of the expression levels of complement-3a receptor 1 and neutrophil extracellular traps in predicting sepsis-induced coagulopathy].

Objectives: To investigate the clinical value of complement-3a receptor 1 (C3aR1) and neutrophil extracellular traps (NETs) in predicting sepsis-induced coagulopathy (SIC).

Methods: A prospective study was conducted among 78 children with sepsis who attended Xuzhou Children's Hospital Affiliated to Xuzhou Medical University from June 2022 to June 2023. According to the presence or absence of SIC, they were divided into two groups: SIC (=36) and non-SIC (=42) .

Effect of HMGB1 on monocyte immune function in respiratory syncytial virus bronchiolitis.

Expression of high mobility group protein box 1 (HMGB1) in children with respiratory syncytial virus bronchiolitis and its effect on the inflammatory function of monocytes were investigated. A total of 30 cases of respiratory syncytial viral bronchitis and 30 cases of healthy persons from physical examination were collected from January 2017 to September 2019 in the pediatric department of Xuzhou Children's Hospital, Xuzhou Medical University. HMGB1 expression level in plasma was detected by ELISA.

Clinical efficacy of montelukast sodium combined with budesonide or combined with loratadine in treating children with cough variant asthma and influence on inflammatory factors in the serum.

Clinical efficacy of montelukast sodium combined with budesonide or combined with loratadine in children with cough variant asthma was investigated. A retrospective analysis of the medical records of 72 children with cough variant asthma who were treated in Xuzhou Children's Hospital, Xuzhou Medical University from April 2015 to August 2017 was performed and the 72 child patients were divided into two groups: 35 children were treated with montelukast sodium combined with budesonide in Group A, and 37 children were treated with montelukast sodium combined with loratadine in Group B. The clinical efficacy of the two groups was evaluated according to the lung function indexes [forced expiratory volume in the first second (FEV1), ratio of the forced expiratory volume in the first second to the forced vital capacity (FEV1/FVC), the peak expiratory flow (PEF)], the inflammation biomarkers [tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4)], the level of eosinophil granulocyte, and the level of IgE at three time-points: before treatment, the 4th week after treatment, and the 12th week after treatment as well as adverse reactions, recurrence of symptoms, and treatment compliance were recorded.

The clinical value of aquaporin-4 in children with hand, foot, and mouth disease and the effect of magnesium sulfate on its expression: a prospective randomized clinical trial.

To evaluate the clinical value of aquaporin-4 (AQP-4) in hand, foot, and mouth disease (HFMD) and to evaluate therapeutic efficacy of magnesium sulfate (MgSO4) and its effect on AQP-4 expression. Children with HFMD were divided into a common group, a severe group and a critical group according to Chinese guidelines; children in the critical group were further divided into two subgroups: routine treatment group and MgSO4 group. Outcome measures included systolic blood pressure (SBP), Heart rate (HR), the levels of AQP-4, interleukin-6 (IL-6), norepinephrine (NE), and neuron-specific enolase (NSE).

Distinct expression and clinical value of aquaporin 4 in children with hand, foot and mouth disease caused by enterovirus 71.

Brain dysfunction is a prerequisite for critical complications in children with hand, foot, and mouth disease (HFMD). Aquaporin 4 (AQP-4) may be involved in the pathological process of cerebral oedema and injury in children with severe and critical HFMD. This study aimed to assess the association of AQP-4 with the severity of enterovirus 71 (EV71)-associated HFMD.

The immune mechanism of intestinal tract Toll-like receptor in mediating EV71 virus type severe hand-foot-and-mouth disease and the MAPK pathway.

Immunological response is thought to play a crucial role in the development of a severe hand-foot-and-mouth disease (HFMD) infection in children, but the mechanisms remain largely unknown. This study was designed to help in elucidating the immunopathological pathways involved in the disease by quantifying Toll-like receptor (TLR) mRNAs, MAPK factors and cytokine levels in children experiencing the disease. A total of 86 enterovirus 71 (EV71)-infected HFMD children (49 with mild and 27 with severe disease), along with 30 healthy children were involved in the study.

[Application of esmolol in severe hand, foot, and mouth disease].

Objective: To study the clinical effect and mechanism of action of esmolol in the treatment of severe hand, foot, and mouth disease (HFMD).

Methods: A prospective randomized controlled trial was performed. A total of 102 children with severe HFMD were enrolled in the study and were randomly divided into conventional treatment and esmolol treatment groups (n=51 each).

Current views of pediatric B cell precursor acute leucoyteic leukemia.

The most common type cancer prevailing in pediatric patients worldwide is acute lymphoblastic leukemia (ALL). The characteristic feature of this cancer is the accumulation of immature lymphoid cell in the bone marrow. Further a subtype of ALL namely B-cell precursor (BCP)-ALL has raised in the recent years and is the most common subtype of ALL prevalent in children worldwide.

[Construction and expression of recombinant plasmid to initiate polarization and activation of regulatory T cells].

In order to construct a recombinant plasmid initiating the polarization and activation of the regulatory T cells (Treg), the fragments of hTGF-β1 and C2-C4 of gp120 amplified by RT-PCR and cloned into pCR2.1 vector respectively. hTGF-β1 and C2-C4 DNA fragments were obtained, then sub-cloned to generate the prokaryotic expression vector named pET-28a/C2-C4-Linker- hTGF-β1.
