The relationship between screen time and attention deficit/hyperactivity disorder in Chinese preschool children under the multichild policy: a cross-sectional survey.

Background: Long screen time has become a public health problem that cannot be ignored. The association between screen time and attention-deficit/hyperactivity disorder (ADHD) in preschool children has received widespread attention.

Methods: A questionnaire was used to survey 2452 people.

MiR-186-5p Dysregulation Leads to Depression-like Behavior by De-repressing SERPINF1 in Hippocampus.

Diagnosis of major depressive disorder (MDD) is perplexing due to its multifactorial etiologies. Here, we isolated exosomes from the peripheral blood of MDD patients and healthy control subjects for mass spectrometry-based label-free quantitative proteomics. We identified that SERPINF1 is significantly diminished in the peripheral blood-derived exosomes of MDD patients compared to the healthy control subjects.

LncRNA MIR155HG regulates M1/M2 macrophage polarization in chronic obstructive pulmonary disease.

Background: Macrophages play a crucial role in inflammatory diseases, including chronic obstructive pulmonary disease (COPD). MIR155 host gene (MIR155HG), a novel long non-coding RNA (lncRNA), has been recognized as a regulator of macrophage polarization, we thus investigated its role in COPD.

Methods: We used granulocyte-macrophage colony-stimulating factor (GM-CSF) to induce peripheral blood mononuclear cells (PBMCs)-derived macrophages obtained from COPD patients and normal controls.

Dual effects of atmospheric pressure plasma jet on skin wound healing of mice.

Cold plasma has become an attractive tool for promoting wound healing and treating skin diseases. This article presents an atmospheric pressure plasma jet (APPJ) generated in argon gas through dielectric barrier discharge, which was applied to superficial skin wounds in BALB/c mice. The mice (n = 50) were assigned randomly into five groups (named A, B, C, D, E) with 10 animals in each group.
