Assembling CdSe Quantum Dots into Polymeric Micelles Formed by a Polyethylenimine-Based Amphiphilic Polymer to Enhance Efficiency and Selectivity of CO-to-CO Photoreduction in Water.

Colloidal quantum dots (QDs) as photocatalysts enable catalysis of CO-to-CO conversion in the presence of electron donors. The surface and/or interfacial chemical environment of the QDs is essential for the activity and selectivity of the CO photoreduction. Various strategies, including exposing active metal sites or anchoring functional organic ligands, have been applied to tune the QDs' surface chemical environment and thus to improve both activity and selectivity of CO photoreduction, which occurs at surface of the QDs.

Clinical and laboratory features, treatment, and outcomes of macrophage activation syndrome in 80 children: a multi-center study in China.

Background: Macrophage activation syndrome (MAS) is a major cause of morbidity and mortality in pediatric rheumatology. We aimed to further understand the clinical features, treatment, and outcome of MAS in China.

Methods: A multi-center cohort study was performed in seven hospitals in China from 2012 to 2018.

Immunological pathogenesis and treatment of systemic lupus erythematosus.

Background: Systemic lupus erythematosis (SLE) is a complex and clinically heterogeneous autoimmune disease. A variety of immunological defects contribute to SLE, including dysregulated innate and adaptive immune response. A clearer understanding of the mechanisms driving disease pathogenesis combined with recent advances in medical science is predicted to enable accelerated progress towards improved SLE-personalized approaches to treatment.

Effect of astragaloside IV against rat myocardial cell apoptosis induced by oxidative stress via mitochondrial ATP-sensitive potassium channels.

Astragaloside is one of the most common traditional Chinese medicines and is derived from Astragalus membranaceus. Astragaloside IV (AsIV) is a monomer located in an extract of astragaloside. The current study investigated the protective effects of AsIV against hydrogen peroxide (H2O2)-induced injury in cardiocytes and elucidated the mechanisms responsible for this protective effect.

Clinical utility of the ventricular septal defect diameter to aorta root diameter ratio to predict early childhood developmental defects or lung infections in patients with perimembranous ventricular septal defect.

Background: Ventricular septal defect (VSD) is the most frequent type of congenital heart disease. Conventional methods to evaluate VSD size and severity are both invasive and cumbersome to perform. We investigated whether the ratio between the diameter of the defect and the aortic root diameter (DVSD/DAR) would accurately reflect the degree of shunted blood and the severity of VSD in children with perimembranous VSD.

Association of high blood pressure with heart rate variability in children.

Objective: To determine the association between heart rate variability (HRV) and hypertension in Chinese children.

Methods: The study was conducted in First Hospital of Jilin University, China. A total of 101 children were recruited in this study.

Multiple organ dysfunction syndrome associated with Mycoplasma pneumoniae infection.

In this study, we report one case of a three-year-old boy infected with Mycoplasma pneumonia (MP) and presenting concomitant multiple organ damage of the heart, kidney, lung and liver, among others, together with a brief review for the diagnosis and treatment of MP infection with multiple organ dysfunction syndrome (MODS).
