Guidelines for the diagnosis and treatment of neurally mediated syncope in children and adolescents (revised 2024).

Background: Significant progress has been made in the diagnosis and treatment of pediatric syncope since the publication of the "2018 Chinese Pediatric Cardiology Society (CPCS) guideline for diagnosis and treatment of syncope in children and adolescents" ("2018 Edition Guidelines"). Therefore, we have revised and updated it to assist pediatricians in effectively managing children with syncope.

Data Sources: According to the "2018 Edition Guidelines", the expert groups collected clinical evidence, evaluated preliminary recommendations, and then organized open-ended discussions to form the recommendations.

A phenome database (NEAUHLFPD) designed and constructed for broiler lines divergently selected for abdominal fat content.

Effective management and analysis of precisely recorded phenotypic traits are important components of the selection and breeding of superior livestocks. Over two decades, we divergently selected chicken lines for abdominal fat content at Northeast Agricultural University (Northeast Agricultural University High and Low Fat, NEAUHLF), and collected large volume of phenotypic data related to the investigation on molecular genetic basis of adipose tissue deposition in broilers. To effectively and systematically store, manage and analyze phenotypic data, we built the NEAUHLF Phenome Database (NEAUHLFPD).

[Research advances in association between vitamin D and Kawasaki disease and related mechanisms of action].

Vitamin D is an important steroid hormone, which has a wide biological effect and is the protective factor against cardiovascular disease and other diseases. At present, the etiology and pathogenesis of Kawasaki disease (KD) remain unknown, but recent studies have shown that vitamin D insufficiency or deficiency is associated with KD. Vitamin D insufficiency or deficiency may affect KD via its influence on inflammatory response, adipokine, endothelial function, platelet function, and DNA methylation and increase the risk of coronary artery lesions.

Effect of Acute and Chronic Exposure to High Altitude on the Aerobic and Anaerobic Metabolism in Rats.

In this study, we aimed to investigate the effect of acute and chronic exposure to HA on the aerobic and anaerobic metabolism in liver by determining the hepatic levels of ICDH and ATP. Lactate levels in liver and blood were also examined. Rats were exposed to an altitude of 4,300 m for 30 days, and those without HA exposure were used as controls.

[Erythrocyte oxidative stress in children with left to right shunt congenital heart disease].

Objective: To study erythrocyte oxidative stress status and its association with left to right shunt congenital heart disease (CHD) in children.

Methods: A total of 31 children with left to right shunt CHD were enrolled, including 7 cases of atrial septal defect (ASD), 12 ventricular septal defect (VSD), 4 patent ductus arteriosus (PDA), 6 patent foramen ovale (PFO), and 2 complete endocardial cushion defect. Twenty healthy age-matched (1 month to 3 years old) children severed as the control group.

[Diagnostic value of plasma brain natriuretic peptide and N-terminal pro-B-type natriuretic peptide in myocardial injury of neonatal septicemia].

Objective: Neonatal sepsis can cause multiple organ dysfunction syndrome, especially including myocardial injury and heart failure. In this study, the authors observed the changes and the levels of plasma brain natriuretic peptide and N-terminal pro-B-type natriuretic peptide in myocardial injury of neonatal sepsis at the different stages to search for the early diagnostic index of myocardial injury and heart failure in patients with neonatal septicemia.

Method: The levels of plasma brain natriuretic peptide and N-terminal pro-B-type natriuretic peptide were determined in 96 newborns with neonatal septicemia according to the diagnosis and treatment program of neonatal septicemia in 2003.
