The paper utilized a standardized methodology to identify prognostic biomarkers in hepatocellular carcinoma(HCC)by analyzing transcriptomic and clinical data from The Cancer Genome Atlas(TCGA)database.The approach,which included stringent data preprocessing,differential gene expression analysis,and Kaplan-Meier survival analysis,provided valuable insights into the genetic underpinnings of HCC.The comprehensive analysis of a dataset involving 370 HCC patients uncovered correlations between survival status and pathological characteristics,including tumor size,lymph node involvement,and distant metastasis.The processed transcriptome dataset,comprising 420 samples and annotating 26,783 genes,served as a robust platform for identifying differential gene expression patterns.Among the significant differential expression genes,the key genes such as FBXO43,HAGLROS,CRISPLD1,LRRC3.DT,and ERN2,were pinpointed,which showed significant associations with patient survival outcomes,indicating their potential as novel prognostic biomarkers.This study can not only enhance the understanding of HCC’s genetic landscape but also establish a blueprint for a standardized process to discover prognostic biomarkers of various diseases using genetic big data.Future research should focus on validating these biomarkers through independent cohorts and exploring their utility in the development of personalized treatment strategies. 展开更多

The security of the seed industry is crucial for ensuring national food security.Currently,developed countries in Europe and America,along with international seed industry giants,have entered the Breeding 4.0 era.This era integrates biotechnology,artificial intelligence(AI),and big data information technology.In contrast,China is still in a transition period between stages 2.0 and 3.0,which primarily relies on conventional selection and molecular breeding.In the context of increasingly complex international situations,accurately identifying core issues in China's seed industry innovation and seizing the frontier of international seed technology are strategically important.These efforts are essential for ensuring food security and revitalizing the seed industry.This paper systematically analyzes the characteristics of crop breeding data from artificial selection to intelligent design breeding.It explores the applications and development trends of AI and big data in modern crop breeding from several key perspectives.These include highthroughput phenotype acquisition and analysis,multiomics big data database and management system construction,AI-based multiomics integrated analysis,and the development of intelligent breeding software tools based on biological big data and AI technology.Based on an in-depth analysis of the current status and challenges of China's seed industry technology development,we propose strategic goals and key tasks for China's new generation of AI and big data-driven intelligent design breeding.These suggestions aim to accelerate the development of an intelligent-driven crop breeding engineering system that features large-scale gene mining,efficient gene manipulation,engineered variety design,and systematized biobreeding.This study provides a theoretical basis and practical guidance for the development of China's seed industry technology. 展开更多

This paper addresses urban sustainability challenges amid global urbanization, emphasizing the need for innova tive approaches aligned with the Sustainable Development Goals. While traditional tools and linear models offer insights, they fall short in presenting a holistic view of complex urban challenges. System dynamics (SD) models that are often utilized to provide holistic, systematic understanding of a research subject, like the urban system, emerge as valuable tools, but data scarcity and theoretical inadequacy pose challenges. The research reviews relevant papers on recent SD model applications in urban sustainability since 2018, categorizing them based on nine key indicators. Among the reviewed papers, data limitations and model assumptions were identified as ma jor challenges in applying SD models to urban sustainability. This led to exploring the transformative potential of big data analytics, a rare approach in this field as identified by this study, to enhance SD models’ empirical foundation. Integrating big data could provide data-driven calibration, potentially improving predictive accuracy and reducing reliance on simplified assumptions. The paper concludes by advocating for new approaches that reduce assumptions and promote real-time applicable models, contributing to a comprehensive understanding of urban sustainability through the synergy of big data and SD models. 展开更多

Viral infectious diseases,characterized by their intricate nature and wide-ranging diversity,pose substantial challenges in the domain of data management.The vast volume of data generated by these diseases,spanning from the molecular mechanisms within cells to large-scale epidemiological patterns,has surpassed the capabilities of traditional analytical methods.In the era of artificial intelligence(AI)and big data,there is an urgent necessity for the optimization of these analytical methods to more effectively handle and utilize the information.Despite the rapid accumulation of data associated with viral infections,the lack of a comprehensive framework for integrating,selecting,and analyzing these datasets has left numerous researchers uncertain about which data to select,how to access it,and how to utilize it most effectively in their research.This review endeavors to fill these gaps by exploring the multifaceted nature of viral infectious diseases and summarizing relevant data across multiple levels,from the molecular details of pathogens to broad epidemiological trends.The scope extends from the micro-scale to the macro-scale,encompassing pathogens,hosts,and vectors.In addition to data summarization,this review thoroughly investigates various dataset sources.It also traces the historical evolution of data collection in the field of viral infectious diseases,highlighting the progress achieved over time.Simultaneously,it evaluates the current limitations that impede data utilization.Furthermore,we propose strategies to surmount these challenges,focusing on the development and application of advanced computational techniques,AI-driven models,and enhanced data integration practices.By providing a comprehensive synthesis of existing knowledge,this review is designed to guide future research and contribute to more informed approaches in the surveillance,prevention,and control of viral infectious diseases,particularly within the context of the expanding big-data landscape. 展开更多

The modernization and internationalization of traditional Chinese medicine(TCM)have long been constrained by the"black box"problem of its complex compositional system and unclear mechanisms of action.Target discovery,as a core step in revealing drug action principles,is key to promoting TCM's transition from"empirical medicine"to"precision medicine".In recent years,the rapid development of chemical biology technologies has provided powerful tools to address this challenge.This article focuses on the latest progress in applying chemical biology strategies,such as molecular probes,click chemistry,fluorescent labeling,and photo-crosslinking microarrays,in TCM target identification research.Combined with typical case studies like Sapanone A and Eupalinolide B,it elaborates on how these cutting-edge technologies can precisely identify the direct targets of active TCM components,thereby achieving comprehensive mechanism analysis from cells and animals to clinical samples.Furthermore,this article prospectively discusses novel"supramolecular drugs"formed by the self-assembly of TCM components at the nanoscale and their unique biological effects.It also preliminarily constructs a modern scientific interpretation framework for TCM theories like"property-flavor-channel tropism"and"processing theory",centered around target distribution and regulation.Finally,this article proposes that"chemical biology of TCM,"as a key driver to discover original drug targets derived from TCM theory,is posited to offer a novel paradigm for innovative drug discovery and to contribute significantly to the modernization and scientific elucidation of TCM theory. 展开更多

Pesticides play a pivotal role in modern agriculture. However, the pesticide industry faces significant challenges closely linked to major global concerns such as pesticide resistance, environmental pollution, food safety, and crop yields. Developing safe, efficient, and environmentally friendly pesticides has become a key challenge for the industry. Recently, Qing Yang and colleagues unveiled the mode of action of a dual-functional protein, the ABCH transporter, which plays essential roles in lipid transport to construct the lipid barrier of insect cuticles and in pesticide detoxification within insects. Since ABCH transporters are critical for all insects but absent in mammals and plants, this elegant and exciting work provides a highly promising target for developing safe, low-resistance pesticides. Here, we highlight the groundbreaking discoveries made by Qing Yang's team in unraveling the intricate mechanisms of the ABCH transporter. 展开更多

Objectives:This study aimed to develop and validate a stroke risk prediction model based on machine learning(ML)and regional healthcare big data,and determine whether it may improve the prediction performance compared with the conventional Logistic Regression(LR)model.Methods:This retrospective cohort study analyzed data from the CHinese Electronic health Records Research in Yinzhou(CHERRY)(2015–2021).We included adults aged 18–75 from the platform who had established records before 2015.Individuals with pre-existing stroke,key data absence,or excessive missingness(>30%)were excluded.Data on demographic,clinical measures,lifestyle factors,comorbidities,and family history of stroke were collected.Variable selection was performed in two stages:an initial screening via univariate analysis,followed by a prioritization of variables based on clinical relevance and actionability,with a focus on those that are modifiable.Stroke prediction models were developed using LR and four ML algorithms:Decision Tree(DT),Random Forest(RF),eXtreme Gradient Boosting(XGBoost),and Back Propagation Neural Network(BPNN).The dataset was split 7:3 for training and validation sets.Performance was assessed using receiver operating characteristic(ROC)curves,calibration,and confusion matrices,and the cutoff value was determined by Youden's index to classify risk groups.Results:The study cohort comprised 92,172 participants with 436 incident stroke cases(incidence rate:474/100,000 person-years).Ultimately,13 predictor variables were included.RF achieved the highest accuracy(0.935),precision(0.923),sensitivity(recall:0.947),and F1 score(0.935).Model evaluation demonstrated superior predictive performance of ML algorithms over conventional LR,with training/validation areaunderthe curve(AUC)sof0.777/0.779(LR),0.921/0.918(BPNN),0.988/0.980(RF),0.980/0.955(DT),and 0.962/0.958(XGBoost).Calibration analysis revealed a better fit for DT,LR and BPNN compared to RF and XGBoost model.Based on the optimal performance of the RF model,the ranking of factors in descending order of importance was:hypertension,age,diabetes,systolic blood pressure,waist,high-density lipoprotein Cholesterol,fasting blood glucose,physical activity,BMI,low-density lipoprotein cholesterol,total cholesterol,dietary habits,and family history of stroke.Using Youden's index as the optimal cutoff,the RF model stratified individuals into high-risk(>0.789)and low-risk(≤0.789)groups with robust discrimination.Conclusions:The ML-based prediction models demonstrated superior performance metrics compared to conventional LR and the RF is the optimal prediction model,providing an effective tool for risk stratifi cation in primary stroke prevention in community settings. 展开更多

Anemoside B4(AB4),a triterpenoidal saponin derived from Pulsatilla chinensis,has garnered considerable attention for its potent anti-inflammatory and immunomodulatory activities,culminating in its approval for clinical trials by the Center for Drug Evaluation,National Medical Products Administration,for the treatment of mild to moderate ulcerative colitis.Despite this,AB4’s therapeutic potential remained underexplored until the development of its injection formulation.This review discusses the scientific rationale and theoretical framework behind AB4’s development,offering a new paradigm and innovative research strategy for discovering lead compounds or drug candidates from natural medicines.In-depth investigations into AB4’s cellular targets,biochemical pathways,and administration routes have provided valuable insights into its druggability evaluation and clinical potential.The high water solubility of AB4,attributable to its multiple sugar units,imposes limitations on its bioavailability and pharmacokinetic profiles.To address this,structural modification via chemical methods and enzymatic hydrolysis have been employed,resulting in derivatives with reduced molecular weight,improved bioavailability,enhanced pharmacological activity,and greater clinical potential.These advances lay a solid foundation for the continued development of AB4 and its derivatives as promising therapeutic agents. 展开更多
