Effect of Astragalus injection treatment for viral myocarditis: a systematic review and meta-analysis.

Background: Astragalus injection has been utilized in traditional Chinese medicine to treat a variety of diseases. The purpose of this systematic review was to evaluate the effectiveness of Astragalus injection in the treatment of viral myocarditis.

Methods: English databases such as PubMed, Cochrane Library, and EMBASE, and Chinese databases of Sino Med, China National Knowledge Infrastructure (CNKI), the VIP Information Resource Integration Service Platform, and Wanfang Data Information Site, were searched from their inception until May 1, 2024.

Digital competency among pediatric healthcare workers and students: a questionnaire survey.

Background: Digital technologies play an important role in improving the quality of healthcare services, however, many healthcare workers and students do not recognize this and have low levels of digital competencies and skills. Therefore, this paper aims to investigate digital perceptions and competencies among medical students in pediatrics and pediatric healthcare workers in China.

Methods: A questionnaire on digital competency was designed.

Ultrasensitive detection of methylene blue by surface-enhanced Raman scattering (SERS) with Ag nanoparticle-decorated magnetic CoNi layered double hydroxides.

The unreasonable use of organic dye leads to excessive residues in environmental water, which seriously threatens human health and the natural environment. In this paper, a spherical flower-like magnetic FeO@CoNi layered double hydroxide@silver nanoparticle (FeO@CoNi LDH@Ag NPs) SERS substrate was successfully fabricated electrostatic self-assembly and applied for the sensitive detection of methylene blue (MB) in environmental water. The rapid concentration and separation of the SERS substrate from the water sample could be achieved using an external magnet.

High-entropy alloys catalyzing polymeric transformation of water pollutants with remarkably improved electron utilization efficiency.

High-entropy alloy nanoparticles (HEA-NPs) exhibit favorable properties in catalytic processes, as their multi-metallic sites ensure both high intrinsic activity and atomic efficiency. However, controlled synthesis of uniform multi-metallic ensembles at the atomic level remains challenging. This study successfully loads HEA-NPs onto a nitrogen-doped carbon carrier (HEAs) and pioneers the application in peroxymonosulfate (PMS) activation to drive Fenton-like oxidation.

Self-assembled hole-selective contact for efficient Sn-Pb perovskite solar cells and all-perovskite tandems.

Self-assembled monolayers (SAMs) have displayed unpredictable potential in efficient perovskite solar cells (PSCs). Yet most of SAMs are largely suitable for pure Pb-based devices, precisely developing promising hole-selective contacts (HSCs) for Sn-based PSCs and exploring the underlying general mechanism are fundamentally desired. Here, based on the prototypical donor-acceptor SAM MPA-BT-BA (BT), oligoether side chains with different length (i.
