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.

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.

Objective To investigate the status of population dynamics and distribution changes of Aedes aegypti in Guangdong Province.Methods Continuous monitoring was conducted from May 2018 to July 2024 in Wushi Town and Qishui Town,Leizhou City,Zhanjiang City,Guangdong Province.Additionally,a survey of the distribution of Ae.aegypti along the Leizhou Peninsula coast was carried out.Results The density of Ae.aegypti in Zhanjiang showed a gradual decline from 2018 to 2024.The last detection of adult Ae.aegypti in Wushi Town was in September 2021,and the last larva was found in October 2023.No Ae.aegypti was detected in Qishui Town during surveys from 2021 to 2024.A survey of 18 coastal villages in the Leizhou Peninsula revealed no detections of Ae.aegypti.Conclusions This study provides a basis for understanding the distribution and population density fluctuations of Ae.aegypti,assessing its invasion risk,and scientifically conducting relevant prevention and control efforts.

This study assessed the role and mechanism of the recombinant Bacillus Calmette-Gue?rin vaccine(rBCG)with c-di-AMP adjuvant in regulating metabolism and immunity in epididymal white adipose(eWAT)in mice.Male C57BL/6 mice were intravenously immunized with BCG and rBCG,and their body weights were monitored.eWAT was isolated from the mice,and the stromal vascular fractions(SVFs)cell number was counted with a hemocytometer.Sections of mouse adipose tissue were prepared,and the size,number,and morphology of eWAT adipocytes and crown-like structure(CLS)formation were compared under a microscope after HE staining.The transcription levels of lipid metabolism-associated factors,cytokines and aging-associated genes in each group were determined with qRT-PCR.The body weights of mice gradually increased after immunization with BCG and rBCG.The proportions of eWAT increased,and the SVFs cell number decreased,in rBCG immunized mice.HE staining indicated that BCG immunization promoted hyperplasia,whereas rBCG immunization promoted hypertrophy of eWAT adipocytes;moreover,both BCG and rBCG immunization induced CLS formation in eWAT.The qRT-PCR results indicated that rBCG immunization inhibited the expression of genes associated with lipolysis and energy expenditure in eWAT.BCG immunization had little effect on cytokine transcription,whereas rBCG significantly induced the transcription of IFN-γ and IL-1Ra,and inhibited that of IL-15 and IL-2,but did not induce the expression of aging-associated genes.Thus,rBCG immunization induced eWAT adipocyte hypertrophy,which was associated with the inhibition of eWAT lipolysis and the regulation of cytokine expression.

Respiratory syncytial virus(RSV)is a ubiquitous respiratory virus that affects individuals of all ages;however,there is a notable lack of targeted treatments.RSV infection is associated with a range of respi-ratory symptoms,including bronchiolitis and pneumonia.Baicalin(BA)exhibits significant therapeutic effects against RSV infection through mechanisms of viral inhibition and anti-inflammatory action.Nonetheless,the clinical application of BA is constrained by its low solubility and bioavailability.In this study,we prepared BA nanodrugs(BA NDs)with enhanced water solubility utilizing the supramolecular self-assembled strategy,and we further conducted a comparative analysis of this pharmacological activity between free drugs and NDs of BA.Both in vitro and in vivo results demonstrated that BA NDs significantly enhanced the dual effects of viral inhibition and inflammation relief compared to free BA,attributed to prolonged lung retention,improved cellular uptake,and increased targeting affinity.Our study confirms that the nanosizing strategy,a straightforward approach to enhance drug solubility,can also increase biological activity compared to free drugs with the same content,thereby providing a potential ND for RSV treatment.This correlation analysis between the existing forms of drugs and their biological activity offers a novel perspective for research on the active ingredients of traditional Chinese medicine.
