Teachers' perception on physical activity promotion in kindergarten children in China: a qualitative study connecting social-ecological model.

Background: Globally, the majority of kindergarten-aged children face obesity issues and insufficient physical activity (PA) engagement. Regular PA participation can provide various health benefits, including obesity reduction, for kindergarten-aged children. However, limited studies have investigated the factors influencing kindergarten-aged children's PA engagement from the perspective of their teachers.

The associations of physical activity and sedentary behavior with self-rated health in Chinese children and adolescents.

Objective: The study aimed to analyze the independent and joint associations of physical activity (PA) and sedentary behavior (SB) with self-rated health (SRH) among Chinese children and adolescents.

Methods: Cross-sectional data on moderate-to-vigorous physical activity (MVPA), school-based PA, extracurricular physical activity (EPA), screen time (ST), homework time, and SRH were assessed through a self-report questionnaire in the sample of 4227 Chinese children and adolescents aged 13.04 ± 2.

IL-1β stimulated human umbilical cord mesenchymal stem cells ameliorate rheumatoid arthritis via inducing apoptosis of fibroblast-like synoviocytes.

Rheumatoid arthritis (RA) is characterized by synovial proliferation and lymphocyte accumulation leading to progressive damage of the periarticular bone and the articular cartilage. The hyperplasia of the synovial intima lining mainly consists of fibroblast-like synoviocytes-rheumatoid arthritis (HFLS-RA) which exhibit apoptosis-resistance, hyper-proliferation, and high invasiveness. The therapeutic efficacy of mesenchymal stem cells (MSCs) treatment in RA has been shown to be due to its immuno-regulatory ability.

Anti-tumor Effects of IL-1β Induced TRAIL-Expressing hUCMSCs on Embelin Treated Breast Cancer Cell Lines.

Background: Human umbilical cord mesenchymal stem cells (hUCMSCs) have high therapeutic value in cancer treatment. We have found that pre-activating hUCMSCs with IL-1β promotes tumor necrosis factor-related apoptosis inducing ligand (TRAIL) expression and facilitates anti-tumor effect. Furthermore, embelin has been found to induce apoptosis of different cancer cell lines by upregulating the expression of TRAIL receptor 1 (DR4) and TRAIL receptor 2 (DR5).

Associations between socioeconomic status and screen time among children and adolescents in China: A cross-sectional study.

Background: Socioeconomic status (SES) is an important determinant of screen time (ST) in children and adolescents, however, the association between SES and ST is not fully understood in China. This study aimed to investigate the association between SES and ST (operationalized as meeting the ST guidelines; no more than 2 hours per day) in Chinese children and adolescents.

Methods: Cross-sectional data of 2,955 Chinese children and adolescents aged 8 to 17(53.

Results from the China 2022 report card on physical activity for children and adolescents.

Background/objective: Regular physical activity (PA) is beneficial to young people's health and development. In order to provide nationally representative and internationally comparable evidence on youth PA, China has participated in Global Matrix 2.0 and 3.

Embelin downregulated cFLIP in breast cancer cell lines facilitate anti-tumor effect of IL-1β-stimulated human umbilical cord mesenchymal stem cells.

Breast cancer is the leading cause of cancer-related death for women. In breast cancer treatment, targeted therapy would be more effective and less harmful than radiotherapy or systemic chemotherapy. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to induce apoptosis in cancer cells but not in normal cells.

Interleukin-1β-induced matrix metalloproteinase-3 via ERK1/2 pathway to promote mesenchymal stem cell migration.

Human umbilical cord Wharton's jelly derived mesenchymal stem cells (hUCMSCs), a source of cell therapy, have received a great deal of attention due to their homing or migrating ability in response to signals emanating from damaged sites. It has been found that IL-1β possesses the ability to induce the expression of matrix metalloproteinase-3 (MMP-3) in bone marrow MSCs. MMP-3 is involved in cell migration in various types of cells, including glioblastoma, vascular smooth muscle, and adult neural progenitor cells.

Interleukin-1 Enhances Umbilical Cord Mesenchymal Stem Cell Adhesion Ability on Human Umbilical Vein Endothelial Cells via LFA-1/ICAM-1 Interaction.

The migration of administered mesenchymal stem cells (MSCs) to sites of injury via the bloodstream has been demonstrated. However, the underlying mechanisms of umbilical cord MSC adhesion to endothelial cells during transendothelial migration are still unclear. In this study, our data showed that IL-1 induced LFA-1 expression on MSCs and ICAM-1 expression on HUVECs.
