Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.

Objective To summarize the perioperative nursing experience for patients undergoing high-risk complex percutaneous coronary intervention(PCI)with the support of the percutaneous transvalvular left-ventricular assist system(SynFlow 3.0),and to explore the role of nursing interventions in improving procedural success and promoting patient recovery.Methods A retrospective analysis was conducted on the clinical data of 26 patients who underwent SynFlow 3.0-assisted high-risk complex PCI in Zhongshan Hospital,Fudan University between Aug 2022 and Jul 2024.Stage-specific comprehensive nursing interventions were implemented throughout the perioperative period:Preoperatively,personalized nutritional support and cardiac function optimization were provided for patients with nutritional risk(NRS≥3),hypoalbuminemia(Alb<30 g/L),or an early warning score≥4.Intraoperatively,the SynFlow 3.0 operational procedures were standardized,with reinforcement of aseptic techniques and hemodynamic monitoring.Postoperatively,patients were transferred to the ICU for continuous monitoring of circulatory parameters(blood pressure,central venous pressure,urine output,etc.)and hemolysis-related indicators,alongside active prevention of vascular complications,vagal reflex,and thrombotic events.Results The procedural success rate was 100%in all 26 patients,with no severe complications occurring.Nursing interventions effectively maintained an intraoperative mean arterial pressure≥60 mmHg.Postoperative circulatory parameters remained stable(systolic blood pressure 90-130 mmHg,urine output>50 mL/h),and no thrombotic or hemolytic events were reported.The left ventricular ejection fraction significantly increased from 32.44%±4.46%preoperatively to 38.55%±5.42%at 30 days postoperatively,and the difference was statistically significant(t=16.065,P<0.001).Conclusion The implementation of a full-process comprehensive nursing strategy for patients undergoing SynFlow 3.0-assisted high-risk complex PCI effectively stabilizes perioperative hemodynamics,reduces the risk of complications,ensures procedural safety,and promotes cardiac function recovery.

Neuroimaging plays a vital role in researching the pathological mechanism of psychiatric disorders. Magnetoencephalography (MEG) non-invasively records the weak magnetic fields generated by neuronal activity, detecting spontaneous brain activity and magnetic responses evoked by auditory, visual, and other stimuli. It offers high temporal and spatial resolution. This article mainly reviews the applications of MEG in psychiatric disorders such as Alzheimer′s disease, schizophrenia, depression, etc., to provide new insights for exploring the pathophysiological mechanism of psychiatric disorders.

In modern society, sugary foods have become an integral part of many people′s lives. However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The "Healthy China Action (2019-2030)" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the "Expert consensus: reducing free-sugar for caries prevention", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world. Combining the actual situation in China, policy recommendations and authoritative popular science knowledge on sugar reduction for caries prevention to public are proposed to advocate for experts in multiple fields to focus on sugar reduction for caries prevention, promote the work process, and provide the scientific basis for oral health educators.

Objective:To investigate whether Porphyromonas gingivalis (Pg) induces ferroptosis in vascular endothelial cells and predict the Hub genes. Methods:Firstly, human umbilical vein endothelial cells (HUVEC) were stimulated with Pg (W83) for 4 h, and transmission electron microscopy was used to observe ferroptosis-related morphological characteristics. Subsequently, RNA was extracted from HUVEC before and after Pg stimulation for transcriptome sequencing (RNA-seq). Enrichment analysis was performed to determine if differentially expressed genes (DEG) associated with ferroptosis. Ferroptosis-related DEG (Fer-DEG) were identified and then underwent gene ontology (GO) functional annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, protein-protein interaction (PPI) network construction, and Hub gene prediction. Next, based on RNA-seq results, HUVEC were stimulated with lipopolysaccharide (LPS) for 24 h. Established ferroptosis markers were detected. The indices and detection methods were as follows: cell viability via cell counting kit-8; reactive oxygen species (ROS) by the DCFH-DA probe; Fe2?, lipid peroxides (LPO), malondialdehyde (MDA), and reduced/oxidized glutathione ratio (GSH/GSSG) with commercial kits; mitochondrial membrane potential (MMP) using the JC-1 probe; solute carrier family 7 member 11 (SLC7A11), solute carrier family 3 member 2 (SLC3A2), and glutathione peroxidase 4 (GPX4) expressions by Western blotting (WB) and real-time fluorescence quantitative PCR (RT-qPCR). Finally, RT-qPCR was used to validate the expression of predicted Hub genes in HUVEC after 24 h LPS stimulation, including tumor necrosis factor (TNF) or TNF-α, interleukin (IL)-6, and prostaglandin-endoperoxide synthase 2 (PTGS2).Results:The mitochondria exhibited size reduction and cristae loss in Pg-stimulated HUVEC. DEG of HUVEC between the Pg-infected and control groups were enriched in the pathway of ferroptosis, and from which 56 Fer-DEG were identified. GO analysis showed enrichment in in responses to TNF, LPS, biotic stimulus, etc. and KEGG analysis revealed enrichment in TNF, C-type lectin receptor, and IL-17 signaling pathways, etc. In the 56-gene PPI network, TNF, IL-6, and PTGS2 were predicted as Hub genes, which were significantly associated with ferroptosis-related pathways, including unsaturated fatty acid biosynthesis and ROS metabolic process regulation. Compared to the control group [(100.00±1.44)%], LPS significantly reduced HUVEC viability [(66.77±1.80)%], which could be ameliorated by Fer-1 [(84.50±1.47)%] ( P<0.05). The ROS fluorescence intensity in the LPS group (1 523.00±250.70) was significantly higher than in the control (328.20±38.68) or LPS+Fer-1 (753.30±67.11) group (all P<0.05). The Fe2?, LPO, and MDA levels in the LPS group [(29.83±4.25) μmol/10 6 cells, (3.58±0.24) μmol/gprot, (5.54±0.33) μmol/gprot, respectively] were significantly higher than both the control group [(7.29±0.79) μmol/10 6 cells, (1.08±0.05) μmol/gprot, (2.06±0.17) μmol/gprot] and the LPS+Fer-1 group [(16.33±1.63) μmol/10 6 cells, (2.01±0.09) μmol/gprot, (3.24±0.26) μmol/gprot]. Furthermore, the GSH/GSSG ratio in the LPS group (2.17±0.08) was considerably lower than both the control group (6.96±0.20) and the LPS+Fer-1 group (4.31±0.81) (all P<0.05). The JC-1 aggregate/monomer fluorescence intensity ratio of the LPS group (0.46±0.07) was markedly lower than the control group (285.60±160.40), while Fer-1 pretreatment (1.53±0.17) obviously mitigated this decrease (all P<0.05). SLC7A11, SLC3A2, and GPX4 protein and mRNA expression levels in the LPS group were dramatically lower than both the control group and the Fer-1+LPS group ( P<0.05). The mRNA expression levels of TNF, IL-6, and PTGS2 in the LPS group were strongly upregulated compared to the control group, and the expressions of these three factors in the LPS+Fer-1 group were significantly lower than those in the LPS group (all P<0.05). Conclusions:Pg drives ferroptosis in vascular endothelial cells, with TNF, IL-6, and PTGS2 identified as the potential novel Hub genes in this process.
