Cardiovascular diseases(CVDs)remain the leading cause of morbidity and mortality worldwide,necessitating innovative diagnostic and prognostic strategies.Traditional biomarkers like C-reactive protein,uric acid,troponin,and natriuretic peptides play crucial roles in CVD management,yet they are often limited by sensitivity and specificity constraints.This narrative review critically examines the emerging landscape of cardiac biomarkers and advocates for a multiple-marker approach to enhance early detection,prognosis,and risk stratification of CVD.In recent years,several novel biomarkers have shown promise in revolutionizing CVD diagnostics.Gamma-glutamyltransferase,microRNAs,endothelial microparticles,placental growth factor,trimethylamine N-oxide,retinol-binding protein 4,copeptin,heart-type fatty acid-binding protein,galectin-3,growth differentiation factor-15,soluble suppression of tumorigenicity 2,fibroblast growth factor 23,and adrenomedullin have emerged as significant indicators of CV health.These biomarkers provide insights into various pathophysiological processes,such as oxidative stress,endothelial dysfunction,inflammation,metabolic disturbances,and myocardial injury.The integration of these novel biomarkers with traditional ones offers a more comprehensive understanding of CVD mechanisms.This multiple-marker approach can improve diagnostic accuracy,allowing for better risk stratification and more personalized treatment strategies.This review underscores the need for continued research to validate the clinical utility of these biomarkers and their potential incorporation into routine clinical practice.By leveraging the strengths of both traditional and novel biomarkers,precise therapeutic plans can be developed,thereby improving the management and prognosis of patients with CVDs.The ongoing exploration and validation of these biomarkers are crucial for advancing CV care and addressing the limitations of current diagnostic tools. 展开更多

In response to the common problems in college English writing teaching,such as the separation of learning and application,students’low interest in writing,and difficulties in expression,this paper,based on the theoretical framework of the production-oriented approach(POA)proposed by Professor Wen Qiufang,designed and implemented a set of IELTS writing teaching plan.This plan takes“motivating,enabling,and assessing”as the core teaching process,and selects typical IELTS argumentative essay topics(such as food diversity)to create real communication scenarios.In the motivating stage,diverse inputs are used to stimulate students’interest and expose their language weaknesses;in the enabling stage,language knowledge,viewpoint generation,and text structure are focused on for targeted input and training;in the assessing stage,a combination of teacher-student cooperation and peer evaluation is adopted to guide students to identify and correct deficiencies in language use.The research results show that the POA model can effectively enhance students’writing interest,active learning awareness,and writing ability,particularly in overcoming vocabulary poverty and material shortages,as well as improving language accuracy and expression richness.This provides an operational theoretical basis and practical path for improving the teaching effect of IELTS writing. 展开更多

Background:Dorsal approach is the potentially effective strategy for minimally invasive liver resection.This study aimed to compare the outcomes between robot-assisted and laparoscopic hemihepatectomy through dorsal approach.Methods:We compared the patients who underwent robot-assisted hemihepatectomy(Rob-HH)and who had laparoscopic hemihepatectomy(Lap-HH)through dorsal approach between January 2020 and December 2022.A 1:1 propensity score-matching(PSM)analysis was performed to minimize bias and confounding factors.Results:Ninety-six patients were included,41 with Rob-HH and 55 with Lap-HH.Among them,58 underwent left hemihepatectomy(LHH)and 38 underwent right hemihepatectomy(RHH).Compared with LapHH group,patients with Rob-HH had less estimated blood loss(median:100.0 vs.300.0 m L,P=0.016),lower blood transfusion rates(4.9%vs.29.1%,P=0.003)and postoperative complication rates(26.8%vs.54.5%,P=0.016).These significant differences consistently existed after PSM and in the LHH subgroups.Furthermore,robot-assisted LHH was associated with decreased Pringle duration(45 vs.60 min,P=0.047).RHH subgroup analysis showed that compared with Lap-RHH,Rob-RHH was associated with less estimated blood loss(200.0 vs.400.0 m L,P=0.013).No significant differences were found in other perioperative outcomes among pre-and post-PSM cohorts,such as Pringle duration,operative time,and hospital stay.Conclusions:The dorsal approach was a safe and feasible strategy for hemi-hepatectomy with favorable outcomes under robot-assisted system in reducing intraoperative blood loss,transfusion,and postoperative complications. 展开更多

Metabolomics utilizes advanced analytical profiling techniques to comprehensively measure small molecules in cells,tissues,and biological fluids.Nutritional metabolomics studies in pigs have reported changes in hundreds of metabolites across various sample types,including plasma,serum,urine,digesta,and feces,following dietary interventions.These findings can help identify biomarkers of gastrointestinal functionality and beyond,as well as investigate mechanistic interactions between diet,host,microbiome,and metabolites.This review aims to summarize the current literature on nutritional metabolomics in pigs and its use to investigate how different dietary approaches impact the gut health of pigs.Here,we critically assessed and categorized the impact of the main macronutrients-carbohydrates,proteins,and fats—along with feed additives such as amino acids,bile acids,and probiotics,as well as feeding strategies like creep feeding,milk replacer introduction,and time-restricted feeding,on the pig metabolome.Additionally,we discuss the potential modes of action of the key affected metabolites on pig gut health. 展开更多

Enhancing the mechanical properties is crucial for polyimide films,but the mechanical properties(Young's modulus,tensile strength,and elongation at break)mutually constrain each other,complicating simultaneous enhancement via traditional trial-and-error methods.In this work,we proposed a materials genome approach to design and screen phenylethynyl-terminated polyimides for films with enhanced mechani-cal properties.We first established machine learning models to predict Young's modulus,tensile strength,and elongation at break to explore the chemical space containing thousands of candidate structures.The accuracies of the machine learning models were verified by molecular dynamics simulations on screened polyimides and experimental testing on three representative polyimide films.The performance advantages of the best-selected polyimides were analyzed by comparing well-known polyimides based on molecular dynamics simulations,and the structural rationale was revealed by"gene"analysis and feature importance evaluation.This work provides a cost-effective strategy for designing polyimide films withenhancedmechanical properties. 展开更多
