本文采用自行搭建的一套液态镓铟锡回路,通过合理地设计液膜生成装置,开展了考虑液膜出口流速、水平磁场强度影响的金属液膜铺展特性实验研究。实验中采用高速摄像法并引入测量微小位移的高精度激光位移传感器获得了大量的金属液膜厚度特征数据。实验结果表明:金属液膜的波动特性随着Re数的增加而逐渐增大,波动从二维波转变成三维波,且高频率的波动逐渐占主导地位,而磁场的增强具有使液膜表面波趋于稳定的效果。

To the Editor:SARS-CoV-2,the pathogen responsible for the pandemic of coronavirus disease 2019(COVID-19),has had profound impacts on human health,and its antagonist Paxlovid is a commonly used treatment option[1].However,treatment selection for immunosuppressed patients,such as liver recipients,remains uncertain due to potential drug interactions and the risk of immunosuppressant dosage adjustment,which can cause liver injury[2].

Objective Brain microvascular endothelial cells (BMECs) were found to shift from their usually inactive state to an active state in ischemic stroke (IS) and cause neuronal damage. Ginsenoside Rb1 (GRb1),a component derived from medicinal plants,is known for its pharmacological benefits in IS,but its protective effects on BMECs have yet to be explored. This study aimed to investigate the potential protective effects of GRb1 on BMECs. Methods An in vitro oxygen-glucose deprivation/reperfusion (OGD/R) model was established to mimic ischemia-reperfusion (I/R) injury. Bulk RNA-sequencing data were analyzed by using the Human Autophagy Database and various bioinformatic tools,including gene set enrichment analysis (GSEA),Gene Ontology (GO) classification and enrichment analysis,Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis,protein-protein interaction network analysis,and molecular docking. Experimental validation was also performed to ensure the reliability of our findings. Results Rb1 had a protective effect on BMECs subjected to OGD/R injury. Specifically,GRb1 was found to modulate the interplay between oxidative stress,apoptosis,and autophagy in BMECs. Key targets such as sequestosome 1 (SQSTM1/p62),autophagy related 5 (ATG5),and hypoxia-inducible factor 1-alpha (HIF-1α) were identified,highlighting their potential roles in mediating the protective effects of GRb1 against IS-induced damage. Conclusion GRbl protects BMECs against OGD/R injury by influencing oxidative stress,apoptosis,and autophagy. The identification of SQSTM1/p62,ATG5,and HIF-1α as promising targets further supports the potential of GRb1 as a therapeutic agent for IS,providing a foundation for future research into its mechanisms and applications in IS treatment.
