MAGI2-AS3 restrains proliferation, glycolysis, and triggers apoptosis in acute lymphoblastic leukemia via regulating miR-452-5p/FOXN3 pathway.

Objectives: MAGI2-AS3 is a cancer suppressor gene of multiple malignancies. Acute lymphoblastic leukemia (ALL) is an important type of leukemia that especially occurs in children. Our work evaluated the modulation of MAGI2-AS3 in ALL.

[Change of serum levels of pentraxin-3 and syndecan-4 in children with chronic heart failure].

Objective: To study the change and significance of serum pentraxin-3 (PTX-3) and syndecan-4 in children with chronic heart failure (CHF).

Methods: A total of 40 children with CHF who were admitted to the Department of Pediatrics of the First Affiliated Hospital of Zhengzhou University were enrolled as the heart failure group, and 30 children who underwent physical examination in the outpatient service during the same period of time were enrolled as the control group. The serum levels of PTX-3, syndecan-4, and N-terminal pro-brain natriuretic peptide (NT-proBNP) were compared between the two groups.

[Clinical manifestations and gene mutation analysis of children with noncompaction of the ventricular myocardium: an analysis of 6 cases].

This article summarizes and analyzes the clinical features and gene mutation characteristics of children with noncompaction of the ventricular myocardium (NVM). For the 6 children with NVM (4 boys and 2 girls), the age of onset ranged from 3 months to 12 years. Of the 6 children, 5 had arrhythmia, 3 had cardiac insufficiency, 1 had poor mental state, and 1 had chest distress and sighing.

[Changes in serum chromogranin A and urotensin II levels in children with chronic heart failure].

Objective: To examine the changes in serum chromogranin A (CgA) and urotensin II (U II) levels in children with chronic heart failure (CHF) and their clinical significance.

Methods: A total of 58 children with CHF, among whom 17 had endocardial fibroelastosis (EFE) and 41 had dilated cardiomyopathy (DCM), were selected as CHF group, and 20 healthy children were selected as control group. Serum levels of CgA and U II were measured using enzyme-linked immunosorbent assay, and the level of N-terminal pro-brain natriuretic peptide (NT-proBNP) was determined by bi-directional lateral flow immunoassay.

[Comparison of prognosis in children with acute viral myocarditis induced ventricular premature beats originating from different positions and the clinical value of mgocardial perfusion ECT].

Objective: To study the difference in prognosis for children with acute viral myocarditis induced ventricular premature beats (VPB) originating from different positions, and to study the role of 99Mtc-MIBI myocardial perfusion ECT in the prognostic evaluation of VPB.

Methods: The clinical data of 83 children with viral myocarditis induced VPB were retrospectively studied. They were divided into four groups according to the original site of VPB, as shown by the ECG: right ventricular (RV) outflow tract, RV anterior wall and apex, left ventricular (LV) outflow tract, LV anterior wall and apex.

[B-type natriuretic peptide (BNP) levels and the effects of carvedilol on BNP levels in juvenile rats with right heart failure].

Objective: To examine serum B-type natriuretic peptide (BNP) levels and BNP expression of protein and mRNA in the right ventricular myocardium in juvenile rats with right heart failure (RHF) and the effects of beta-adrenergic receptor blocker carvedilol on serum and myocardial BNP levels in order to investigate the role of BNP in the diagnosis and treatment of RHF.

Methods: Fifty-one four-week-old Sprague-Dawley rats were randomly assigned to 5 groups: RHF 1, RHF 2, carvedilol-treated RHF, control 1 and control 2. RHF was developed 4 weeks after an intraperitoneal injection of monocrotaline in the RHF 1, RHF 2 and carvedilol-treated RHF groups.

[Levels of serum brain natriuretic peptide in children with congestive heart failure or with severe pneumonia].

Objective: Some research has shown that B-type brain natriuretic peptide (BNF) is helpful in differentiating cardiac from pulmonary etiologies of dyspnea in adults. This study was designed to investigate whether BNP concentration could be similarly applied in children presenting with dyspnea.

Methods: Blood samples were collected from 65 children presenting with dyspnea, due to congestive heart failure (CHF, n=24), pneumonia (n=23) or pneumonia together with CHF (n=18).
