文摘BACKGROUND Depression is a significant risk factor for diabetes,particularly type 2 diabetes.However,depressive symptoms differ from clinical depression.Previous research has not fully considered the relationship between the trajectory of depressive symptoms and the risk of developing diabetes over time.AIM To investigate the association between depressive symptoms,their trajectories,and the risk of developing diabetes in two prospective cohort studies.METHODS In the first phase we analyzed the association between depressive symptoms and the risk of developing diabetes separately using the Health and Retirement Study(HRS).Depressive symptom trajectories were assessed by examining changes in depressive symptoms at baseline and again 8 years later.We then identified specific depressive symptom trajectories that increased the risk of diabetes in the second phase.Finally,we confirmed the association between depressive symptoms and their trajectories with diabetes risk using the English Longitudinal Study of Ageing(ELSA)as a validation study.Depressive symptom trajectories were categorized into five states based on changes in the modified 8-item Center for Epidemiological Studies-Depression scores:Persistently high;increasing;fluctuating;decreasing;and persistently low.Diabetes mellitus was defined as self-reported,physician-diagnosed diabetes.Cox proportional hazards models were used to assess hazard ratios(HR)and 95%confidence intervals(CI),adjusting for potential confounders.RESULTS In the first phase a total of 27658 participants were included(HRS:18633,ELSA:9025),among whom 6582 had depressive symptoms(HRS:4547,ELSA:2035),6407 had somatic depressive symptoms(HRS:4414,ELSA:1993),and 26415 had cognitive-affective depressive symptoms(HRS:17755,ELSA:8660).We found that overall depressive symptoms(HRS:HR=1.14,95%CI:1.07-1.22;ELSA:HR=1.18,95%CI:1.03-1.34)and somatic depressive symptoms(HRS:HR=1.14,95%CI:1.07-1.22;ELSA:HR=1.25,95%CI:1.10-1.42)increased the risk of diabetes,while cognitive depressive symptoms were not associated with diabetes risk.Over an 8-year follow-up we identified 19729 trajectories of overall,somatic,and cognitive-affective depressive symptoms(HRS:13918,ELSA:5811).In the second phase we found that persistently high(HRS:HR=1.22,95%CI:1.06-1.40,ELSA:HR=1.54,95%CI:1.16-2.05 in total and HRS:HR=1.24,95%CI:1.07-1.43,ELSA:HR=1.79,95%CI:1.36-2.35 in somatic)and fluctuating(HRS:HR=1.09,95%CI:1.01-1.17,ELSA:HR=1.33,95%CI:1.14-1.55 in total and HRS:HR=1.10,95%CI:1.02-1.18,ELSA:HR=1.31,95%CI:1.13-1.53 in somatic)trajectories of overall and somatic depressive symptoms increased the risk of diabetes,while increasing trajectories may also raise diabetes risk.However,decreasing trajectories were not associated with diabetes risk.Cognitive-affective depressive symptoms showed no association with diabetes risk regardless of trajectory changes.Sensitivity analyses confirmed the reliability of the findings.CONCLUSION Persistently high and fluctuating trajectories of overall and somatic depressive symptoms increased the risk of diabetes,while decreasing trajectories were not associated with diabetes risk.In contrast trajectories of cognitiveaffective depressive symptoms show no relationship with diabetes risk.Focusing on depressive symptom trajectories,particularly those of somatic depressive symptoms,represented a viable strategy for future diabetes prevention.
文摘The hybridity of words in literary texts and the multiplicity of theoretical discourse fundamentally determine the cross-cultural attributes of literary studies.This feature holds significant value for understanding different cultural traditions and presenting one’s cultural traits in a mutually contextualized manner.By analyzing the cross-cultural essence of literary studies with a focus on word transformation and critical discourse and also emphasizing that literary studies should fully consider the linguistic elements of literary texts,the theoretical origins of critical terminology,and the cultural stance of the researcher,it becomes possible to understand the important role of literary studies in humanistic academic knowledge production.

文摘Background:Cardiorespiratory fitness(CRF)is a powerful health marker recommended by the American Heart Association as a clinical vital sign.Comparing the predictive validity of objectively measured CRF(the"gold standara")and estimated CRF is clinically relevant because estimated CRF is more feasible.Our objective was to meta-analyze cohort studies to compare the associations of objectively measured,exerciseestimated,and non-exercise-estimated CRF with all-cause and cardiovascular disease(CVD)mortality in adults.Methods:Systematic searches were conducted in 9 databases(MEDLINE,SPORTDiscus,Embase,Scopus,PsycINFO,Web of Science,PubMed,CINAHL,and the Cochrane Library)up to April 11,2024.We included full-text refereed cohort studies published in English that quantified the association(using risk estimates with 95%confidence intervals(95%CIs))of objectively measured,exercise-estimated,and non-exercise-estimated CRF with all-cause and CVD mortality in adults.CRF was expressed as metabolic equivalents(METs)of task.Pooled relative risks(RR)for all-cause and CVD mortality per 1-MET(3.5 mL/kg/min)higher level of CRF were quantified using random-effects models.Results:Forty-two studies representing 35 cohorts and 3,813,484 observations(81%male)(362,771 all-cause and 56,471 CVD deaths)were included.The pooled RRs for all-cause and CVD mortality per higher MET were 0.86(95%CI:0.83-0.88)and 0.84(95%CI:0.80-0.87),respectively.For both all-cause and CVD mortality,there were no statistically significant differences in RR per higher MET between objectively measured(RR range:0.86-0.90)and maximal exercise-estimated(RR range:0.85-0.86),submaximal exercise-estimated(RR range:0.91-0.94),and non-exercise-estimated CRF(RR range:0.81-0.85).Conclusion:Objectively measured and estimated CRF showed similar dose-response associations for all-cause and CVD mortality in adults.Estimated CRF could provide a practical and robust alternative to objectively measured CRF for assessing mortality risk across diverse populations.Our findings underscore the health-related benefits of higher CRF and advocate for its integration into clinical practice to enhance risk stratification.
文摘Background:Pistacia integerrima,a cornerstone of traditional medicine,is renowned for its therapeutic applications against various health conditions,including cancer and hepatitis.This study investigates the pharmacological potential of bioactive compounds derived from Pistacia integerrima in inhibiting 5-lipoxygenase(5-LOX),a key enzyme implicated in inflammation and cancer progression.The current study aimed to evaluate the lipoxygenase inhibitory activity of bioactive compounds from Pistacia integerrima and assess their potential for therapeutic development in the context of inflammation and cancer treatment.Methods:Three major compounds-spinacetin(1),patuletin(2),and pistagremic acid(3)-were isolated from Pistacia integerrima and analyzed for their lipoxygenase inhibitory activity.Biochemical assays and molecular docking studies were performed to assess their effectiveness in inhibiting 5-LOX.Results:All three compounds demonstrated significant inhibition of lipoxygenase activity.Spinacetin(1)and patuletin(2)exhibited the most potent inhibitory effects,with IC_(50)values of 40.34μM and 45.04μM,respectively.Molecular docking studies revealed that patuletin(2)had the highest binding affinity(−7.717 kcal/mol)against 5-LOX,followed by spinacetin(1)with a binding affinity of−6.074 kcal/mol.In-depth in silico analysis highlighted the drug-likeness of spinacetin(1)and its favorable toxicological profile,suggesting its suitability for therapeutic development.Conclusion:The study demonstrates that compounds from Pistacia integerrima,particularly spinacetin and patuletin,have significant lipoxygenase inhibitory activity,with spinacetin showing promise as a lead candidate for lipoxygenase-targeted therapies.The findings reinforce the therapeutic relevance of Pistacia integerrima and suggest that its bioactive compounds may serve as safer,plant-based alternatives to conventional anti-inflammatory and anticancer treatments.
文摘The effect of prenatal exposure to ambient particulate matter(PM)on birth weight varies considerably across studies,and the findings remain inconclusive.In this study,we conducted a meta-analysis to assess the associations between exposure to PM_(2.5) and PM10 and birth weight.A total of 74 studies were identified through searches in Web of Science,PubMed,Embase,and Ovid Medline,as well as manual searches,up to October 2024.We found that for each 10μg/m^(3) increase in PM_(2.5),the risk of low birth weight(LBW)increased significantly during the entire pregnancy(odds ratio[OR]=2.41,95%confidence interval[CI]:1.99–2.91)and in all trimesters.Similarly,for every 10μg/m^(3) increase in PM10 concentration,the risk of LBW increased significantly during the entire pregnancy(OR=1.46,95%CI:1.16–1.84).Subgroup analysis by maternal age for PM_(2.5) showed that mothers aged 30 and above had a significantly higher risk of LBW(OR=3.69,95%CI:2.81–4.84),compared with those under 30.In conclusion,maternal exposure to PM_(2.5) and PM_(10) is associated with an increased risk of LBW across all trimesters.Additionally,mothers aged 30 and above are at a higher risk of LBW,compared with younger mothers.Further research is needed to clarify the biological mechanisms by which PM pollution may contribute to LBW.
文摘BACKGROUND Gastrointestinal endoscopy has been widely used in the diagnosis and treatment of gastrointestinal diseases.A great many of studies on gastrointestinal endoscopy have been done.AIM To analyze the characteristics of top 100 cited articles on gastrointestinal endoscopy.METHODS A bibliometric analysis was conducted.The publications and their features were extracted from the Web of Science Core Collection,Science Citation Index-Expanded database.Excel,Web of Science database and SPSS software were used to perform the statistical description and analysis.VOSviewer software and Map-Chart were responsible for the visualizations.RESULTS The top 100 cited articles were published between 1976 and 2022.The guidelines(52%)and clinical trials(37%)are the main article types,and average publication year of the guidelines is much later than that of the clinical trials(2015 vs 1998).Among the clinical trials,diagnostic study(27.0%),cohort study(21.6%),case series(13.5%)and cross-sectional study(10.8%)account for a large proportion.Average citations of different study types and designs of the enrolled studies are of no significant differences.Most of the 100 articles were published by European authors and recorded by the endoscopic journals(65%).Top journals in medicine,such as the Lancet,New England Journal of Medicine and JAMA,also reported studies in this field.The hot spots of involved diseases include neoplasm or cancer-related diseases,inflammatory diseases,obstructive diseases,gastrointestinal hemorrhage and ulcer.Endoscopic surgery,endoscopic therapy and stent placement are frequently studied.CONCLUSION Our research contributes to delineating the field and identifying the characteristics of the most highly cited articles.It is noteworthy that there is a significantly smaller number of clinical trials included compared to guidelines,indicating potential areas for future high-quality clinical trials.
基金Research topic of Southwest Forestry University:“Research on Countermeasures to Improve the Postgraduate Entrance Rate of Undergraduates under the Background of Employment Pressure”(QN202308)。
文摘Against the backdrop of employment pressure,pursuing graduate studies has become a crucial pathway for undergraduate students to enhance employment competitiveness and alleviate employment challenges.However,the recent downward trend in graduate school applicants has rendered the improvement of undergraduates’willingness to pursue advanced degrees an urgent practical issue.This study employs a questionnaire survey method to empirically investigate the influencing factors of undergraduates’intention to pursue graduate studies.The findings reveal that at the individual level,preparation difficulty,preparation pressure,clarity of goals,and academic planning significantly affect students’willingness to pursue graduate studies.At the family level,preparation costs and family atmosphere exert substantial influence on this decision-making process.Accordingly,this paper proposes enhancement strategies from both individual and family perspectives to improve enrollment rates.Students should establish clear academic objectives and strengthen psychological adjustment,while families ought to provide robust financial support and foster harmonious environments.These recommendations aim to effectively boost undergraduates’motivation for graduate education.

文摘Tick studies in Malaysia have experienced a dynamic evolution characterized by periods of growth,stagnation,and the potential for revival.Beginning during the colonial era in the early 1900s,tick studies were primarily conducted by European scientists and curators,establishing the foundation for tick taxonomy in the region.Pioneering works by George Henry Falknier Nuttall and Cecil Warburton introduced several new tick species,including Haemaphysalis(H.)calva,H.mjoebergi,H.vidua and H.wellingtoni[1].However,some records from this period are now considered doubtful,for instance Amblyomma(A.)breviscutatum,A.clypeolatum and A.integrum.The 1929 description of Ornithodoros batuensis by Stanley Hirst[2]marked the first documentation of a soft tick species in Malaysia,setting the stage for subsequent research endeavours.The Golden Age of tick studies(early 1950s-late 1980s)in Malaysia saw a surge in tick research activities.
基金a phased achievement of the“Research on Chinese Confucian Orthodoxy”(Project No.:17ZDA010),a major project of the National Social Science Fund of China.
文摘Continuity is the foremost defining characteristic of Chinese civilization.It ensures that the evolution of this civilization respects the fine traditions and stays on the right course throughout its creative course.Meanwhile,creativity imparts ceaseless vitality to this civilization,serving as the intrinsic propulsive force that fuels its evolution.The rise of Song Studies marks one of the symbolic events in the transformation in the Chinese ideological and cultural realm.It encapsulates the dialectical unity between continuity and creativity that characterizes Chinese civilization.Song Studies adhere to the traditional classic interpretations,center the core values around“benevolence,”and pursue the way of sages,which reflect the continuity of Chinese civilization.They also embody creativity.This is manifested in the emergence of a new academic spirit that emphasizes the seeking of truth and reason,a new academic ethos that involves questioning classics in the process of their dissemination and interpreting them with one’s own insight,as well as the fusion of philosophical speculation with social practice.Conducting an integrated analysis of the defining characteristics of Chinese civilization and the rise of Song Studies helps us gain a thorough understanding of the dialectical unity between the continuity and creativity of Chinese civilization through the interactions between history and reality.It also enables us to effectively address the relationship between inheritance and transformation,as well as between maintaining core values and pursuing creativity throughout its ongoing development.

文摘Man-made superheavy elements(SHE)are produced as energetic recoils in complete-fusion reactions and need to be thermalized in a gas-filled chamber for chemical studies.The ever-shorter half-lives and decreasing production rates of the elements beyond Fl(atomic number Z=114)-the heaviest element chemically studied today-require the development of novel techniques for quantitative thermalization and fast extraction efficiency.The Universal high-density gas stopping Cell(UniCell),currently under construction,was proposed to achieve this.Within this work,we propose an Ion Transfer by Gas Flow(ITGF)device,which serves as a UniCell ejector to interface with a gas chromatography detector array for chemical studies.Detailed parameter optimizations,using gas dynamics and Monte Carlo ion-trajectory simulations,promise fast(within a few ms)and highly efficient(up to 100%)ion extraction across a wide mass range.These ions can then be transmitted quantitatively through the ITGF into the high-pressure environment needed for further chemical studies.

文摘Objective Observational studies have found associations between inflammatory bowel disease(IBD)and the risk of dementia,including Alzheimer’s dementia(AD)and vascular dementia(VD);however,these findings are inconsistent.It remains unclear whether these associations are causal.Methods We conducted a meta-analysis by systematically searching for observational studies on the association between IBD and dementia.Mendelian randomization(MR)analysis based on summary genome-wide association studies(GWASs)was performed.Genetic correlation and Bayesian colocalization analyses were used to provide robust genetic evidence.Results Ten observational studies involving 80,565,688 participants were included in this metaanalysis.IBD was significantly associated with dementia(risk ratio[RR]=1.36,95%CI=1.04-1.78;I2=84.8%)and VD(RR=2.60,95%CI=1.18-5.70;only one study),but not with AD(RR=2.00,95%CI=0.96-4.13;I^(2)=99.8%).MR analyses did not supported significant causal associations of IBD with dementia(dementia:odds ratio[OR]=1.01,95%CI=0.98-1.03;AD:OR=0.98,95%CI=0.95-1.01;VD:OR=1.02,95%CI=0.97-1.07).In addition,genetic correlation and co-localization analyses did not reveal any genetic associations between IBD and dementia.Conclusion Our study did not provide genetic evidence for a causal association between IBD and dementia risk.The increased risk of dementia observed in observational studies may be attributed to unobserved confounding factors or detection bias.
文摘Background:Foreign Language Anxiety(FLA)represents a substantial affective barrier that undermines cognitive performance,motivation,and retention in language learners.Emerging evidence highlights mindfulness-based interventions as promising strategies for enhancing emotional regulation and reducing anxiety across educational contexts.This review synthesizes current research on mindfulness as a psychological intervention,aims to evaluate its efficacy in alleviating FLA,and discusses its broader implications for health-focused educational policy and practice.Methods:Following PRISMA guidelines,we systematically reviewed studies examining the relationships between mindfulness and FLA.Our search of four major databases(November 2023)initially identified 346 articles using terms like“mindfulness AND language anxiety.”After screening,14 studies met our criteria:(1)empirical research in English on mindfulness-FLA relationships;(2)no publication date restrictions.Two independent reviewers selected studies,excluding two due to methodological limitations.We conducted a narrative synthesis given the study heterogeneity(9 correlational and 5 intervention studies).Results:9 non-intervention studies demonstrated that mindfulness is negatively associated with FLA,with 3 studies highlighting the mediating roles of self-efficacy and resilience.5 intervention studies reported inconsistent results regarding the efficacy of mindfulness-based interventions in reducing FLA.Conclusions:The findings suggest that while mindfulness holds promise as a tool to address FLA,its mechanisms and effectiveness require further investigation.This study underscores the need for rigorous research,including Randomized Controlled Trials(RCTs),to inform evidence-based integration of mindfulness into foreign language curricula.For educational policymakers and practitioners,these insights highlight the importance of adopting mindfulness interventions cautiously,ensuring they are tailored to students’needs and supported by evidence.
文摘The learning of English academic vocabulary has been the focus of numerous studies from the time Coxhead(2000)developed the academic word list to the present day.Various researchers have emphasized the importance of possessing academic vocabulary knowledge for academic success.Recognizing this importance,it is crucial for researchers,teachers,and learners to understand the progress made in academic word lists.This systematic review first identifies,describes,appraises,and synthesizes the development of academic word lists from 2000 to 2020.It then examines the methods used by researchers in developing academic word lists among 56 studies that meet the pre-established criteria.The word lists were classified based on some criteria such as word counting units,corpora types/sizes,and exclusion criteria.Limitations,suggestions for further study,and implications are also discussed.Additionally,recommendations for future word list establishment are provided to help advance the field of word list development.

文摘Background:Rice grain morphology—including traits such as awn length,hull color,size,and shape—is of central importance to yield,quality,and domestication,yet comprehensive quantification at scale has remained challenging.Apromising solution has been provided by the integration of high-throughput imaging with genomic analysis.Methods:A standardized 2D image-processing pipeline was established to extract four categories of traits—awn length,hull color,projected grain area,and shape descriptors via PCA of normalized contours—from high-resolution photographs of 229 Oryza sativa japonica landraces.Genome-wide association analyses were then performed using a mixed linearmodel to control for population structure and kinship.Results:Broad phenotypic diversity was evident in awn length,hull coloration,grain dimensions,and morphological shape,with the first principal component explaining the dominant axis of shape variation.Known awn regulators GAD1/OsRAE2(chr 8;P=4.75×10^(-17))and An-1(chr 4;P=1.91×10^(-6))were identified.The hull color gene Rd(chr 1;P=3.13×10^(-6))was detected.A novel locus on chr 12 at 8.75 Mb with Os12g0257600(P=1.41×10^(-8)),and the known grain size gene FLO2(chr 4;P=8.28×10^(-6))were associated with projected area.Shape PC1 was mapped to GLW7/OsSPL13(chr 7;P=3.86×10^(-10)),NAL2/OsWOX3A(chr 11;P=1.41×10^(-11)),and OsGIF1(chr 11;P=1.27×10^(-8)).Conclusions:This study demonstrates that image-based phenotyping combined with genome-wide association studies(GWAS)can efficiently reveal both established and novel genetic determinants of rice grain morphology.These findings provide actionable targets for marker-assisted selection and genome editing to tailor grain traits in rice breeding programs.
文摘BACKGROUND Laparoscopic one anastomosis gastric bypass(OAGB)has grown in popularity in recent years for the treatment of morbid obesity.Despite routine practice,the utility of early postoperative upper gastrointestinal(UGI)swallow studies to detect complications following OAGB has been questioned.AIM To evaluate the effectiveness and cost-efficiency of performing routine UGI studies on the first postoperative day(POD)after OAGB.METHODS A retrospective cohort analysis of a prospectively collected database was conducted to identify all consecutive patients who underwent OAGB between January 2019 and July 2022.Patient demographics,operative data,and postoperative complication rates were analyzed.Reports from all imaging studies were retrospectively reviewed,and complications were recorded.The institutional review board waived the requirement for informed consent.RESULTS A total of 385 patients were included.All patients had an iodine-based contrast swallow study on the first POD.Abnormal findings were observed in 4 patients(1%),none of which were correlated with postoperative complications.Two patients(0.5%)required reoperation due to complications although both had normal UGI study results.Sensitivity and positive predictive value of UGI studies for detecting complications were 0%,while specificity and negative predictive value were 99%and 98%,respectively.Based on hospital charges the overall cost of all the UGI swallow studies performed in our study was 95865 USD.CONCLUSION The study findings showed that performing routine UGI swallow studies on the first POD after laparoscopic OAGB is ineffective in detecting complications and is not cost effective.Normal UGI studies might mislead clinicians in the postoperative period and thus should be omitted in favor of close clinical monitoring.
文摘In modern society,the globalization of literary works is evident,with exceptional literary pieces from various countries spreading worldwide.Among these,children’s literature,due to the specificity of its target audience,imposes distinct requirements on children’s books,compelling translators to approach the text from a child’s perspective.“The Little Prince”has renowned both within and outside of China,and a careful reading of this work can provide us with much inspiration.To this end,the present study adopts the perspective of Gideon Toury’s Descriptive Translation Studies to conduct an in-depth analysis of the different English and Chinese translations in conjunction with the original French novel.This approach aims to better guide literary research and explores translation methods for children’s literature through the analysis of translation norms and rules.
