Due to the wide application of rare earth elements,lanthanum(La) is gradually accumulated in our living environment.Lanthanum can enter the body through a variety of routes,which has a series of effects on various systems.As a consequence,the safety of lanthanum deserves our attention.This study aims to compare the toxicity of lanthanum oxide nanoparticles(La_(2)O_(3) NPs) and lanthanum chloride(LaCl_(3)) and enrich the toxicity evaluation of lanthanum.Therefore,a 30 d intragastal experiment was conducted.C57BL/6j mice were given by La_(2)O_(3) NPs solution and LaCl_(3) solution respectively at doses of 0,30,60 and120 mg/kg BW(lanthanum content).The results show that,compared with the control group,both La_(2)O_(3)NPs and LaCl_(3) can reduce the body weight of female mice in the high-dose group,but for male mice,the high-dose La_(2)O_(3) NPs solution can increase the body weight,while LaCl_(3) has the opposite effect.The coefficients of liver,kidney,heart,lung,uterine and ovaries increase first and then decrease with the exposure dose,but testes and epididymides coefficient keep increasing with the exposure of LaCl_(3) and La_(2)O_(3) NPs.La_(2)O_(3) NPs and LaCl_(3) can reduce the concentration of triglycerides(TG) and increase the level of low density lipoprotein(LDL),but the effect of La_(2)O_(3) NPs is more obvious.La_(2)O_(3) NPs and LaCl_(3) can reduce the concentration of malondialdehyde(MDA),increase the total antioxidant capacity(T-AOC)and enhance the activity of catalase(CAT),but LaCl_(3) has more obvious protective effects on oxidative stress.La_(2)O_(3) NPs and LaCl_(3) have potential risks to liver,and the toxicity of La_(2)O_(3) NPs might be higher than that of LaCl_(3).

This paper discusses ways in which negative economic shocks captured by natural disasters can shape internal labor migration in China.The impact of negative economic shocks on migration depends on the combination of two opposite driving forces:(i)negative economic shocks can make staying in the affected area less profitable,thus enhancing returns to migration;(ii)the shocks can make it more difficult to migrate out,thus inducing a higher fixed cost of migration.Based on a nationwide dataset of China,this paper shows that when natural disasters were not severe,they caused migration out of rural areas.With sufficiently severe damage,however,the negative effect of natural disasters could be mitigated by villages'prior migrant networks.Specifically,with a severe shock,only clan members were able to migrate in response to natural disasters and enjoyed the complementary effects of prior migrant networks,as they could receive more help from social capital.

Objective:This study aims to provide a theoretical foundation for the development and practical application of human immunodeficiency virus(HIV)/acquired immunodeficiency syndrome(AIDS)prevention and control policy systems in China by scrutinizing,analyzing,and synthesizing the evolution of Chinese policies in this domain.Methods:Utilizing grounded theory,we employed NVivo12 software to perform text content analysis,mining,and coding classification,along with visualization techniques,on policy texts sourced from Chinese government platforms,including the official website of China’s State Council.We considered four analytical dimensions—time,subject,type,and object.Results:The National Health Commission and the State Council emerged as the primary entities engaged in policymaking for HIV/AIDS in China.We identified four distinct stages in the evolution of these policies,culminating in a novel‘sun-shaped’HIV/AIDS prevention and control policy network model with an emphasis on‘knowledge,attitude,and practice’at its nucleus,which aligns with national conditions and societal progress.Furthermore,the focal groups of these policies have been dynamically refined and updated over time.Conclusions:Our findings introduce a‘sunshaped’HIV/AIDS prevention and control policy network model specific to China.We observed a conceptual policy shift towards prioritizing overall human health rather than confining the focus to disease treatment.Additionally,in light of China’s growing elderly population,the imperative to address HIV/AIDS prevention and control among older adults is an issue that warrants increased attention.

The interplay between financial technology(FinTech)and real economy firms has garnered considerable attention.This paper explores the relationship and mechanism between FinTech and corporate zombification using the data of Chinese A-share listed firms in China from 2011 to 2021.The research findings reveal that FinTech significantly inhibits firm zombification,and FinTech breadth and depth both play a significant role in restraining firm zombification.Mechanism exploration indicates that,on the one hand,FinTech reduces friction in the financial market,inhibiting firm zombification by improving firm investment efficiency,especially alleviating under-investment.On the other side,FinTech indirectly affects the technological investment,production,and operation of firms,thereby inhibiting firm zombification by increasing their total factor productivity.Heterogeneity analysis suggests that the inhibitory effect of FinTech on corporate zombification is more pronounced for non-stateowned firms and small-sized firms,as well as those in manufacturing industries and highly competitive industries.This paper provides some novel evidence on evaluating the effect of FinTech on firms and also offers new insights for efficient governance of zombie firms.

Socioecological inequity in environmental data science—such as inequities deriving from data-driven approaches and machine learning(ML)—are current issues subject to debate and evolution.There is growing consensus around embedding equity throughout all research and design domains—from inception to administration,while also addressing procedural,distributive,and recognitional factors.Yet,practically doing so may seem onerous or daunting to some.The current perspective helps to alleviate these types of concerns by providing substantiation for the connection between environmental data science and socioecological inequity,using the Systemic Equity Framework,and provides the foundation for a paradigmatic shift toward normalizing the use of equity-centered approaches in environmental data science and ML settings.Bolstering the integrity of environmental data science and ML is just beginning from an equity-centered tool development and rigorous application standpoint.To this end,this perspective also provides relevant future directions and challenges by overviewing some meaningful tools and strategies—such as applying the Wells-Du Bois Protocol,employing fairness metrics,and systematically addressing irreproducibility;emerging needs and proposals—such as addressing data-proxy bias and supporting convergence research;and establishes a ten-step path forward.Afterall,the work that environmental scientists and engineers do ultimately affect the well-being of us all.

Background Bipolar disorder is identified as a cause of severe damage to the physical,psychological and social functioning of adolescents and young adults.Aims The aim of this study is to ascertain the trends in the burden of bipolar disorder among individuals aged 10-24 years at global,regional and national levels from 1990 to 2019.Methods The data analysed in this study were from the Global Burden of Diseases 2019.The numbers,rates per 100000 population,average annual percentage changes(AAPCs)of incidence,prevalence and years lived with disability(YLDs)of bipolar disorder are reported at the global,regional and national levels among individuals aged 10-24 years.Global trends by age,sex and Social Development Index(SDI)were further analysed.Results Globally,the incidence of bipolar disorder among adolescents and young adults increased from 79.21 per 100000 population(95%uncertainty interval(Ul):58.13 to 105.15)in 1990 to 84.97 per 100000 population(95%Ul:61.73 to 113.46)in 2019,AAPC 0.24(95%confidence interval(Cl):0.22 to 0.26).In the past three decades,there has been an increase in incidence,prevalence and YLDs in both males and females.The largest increase in incidence between 1990 and 2019 was observed in those aged 20-24 years old from 51.76 per 100000 population(95%Ul:26.81 to 87.20)in 1990 to 58.37 per 100000 population(95%UI:30.39 to 98.55)in 2019;AAPC 0.42(95%Cl:0.38 to 0.47).By the SDI quintile,the largest increase in incidence was observed in the middle SDl;however,the high SDI countries had the highest incidence.Regionally,the largest increase in incidence was observed in southern Latin America.At the national level,the most pronounced increase in the incidence was in Greenland.Conclusions The global increase in incidence among adolescents and young adults between 1990 and 2019 indicates that strategies to improve their mental health still need to be emphasised.

Introduction:Childhood circumstances impact senior health,prompting the introduction of machine learning methods to assess their individual and collective contributions to senior health.Methods:Using health and retirement study(HRS)and China Health and Retirement Longitudinal Study(CHARLS),we analyzed 2,434 American and 5,612 Chinese participants aged 60 and above.Conditional inference trees and forests were employed to estimate the influence of childhood circumstances on self-rated health(SRH).Results:The conventional method estimated higher inequality of opportunity(IOP)values in both China(0.039,accounting for 22.67%of the total Gini coefficient 0.172)and the US(0.067,accounting for 35.08%of the total Gini coefficient 0.191).In contrast,the conditional inference tree yielded lower estimates(China:0.022,accounting for 12.79%of 0.172;US:0.044,accounting for 23.04%of 0.191),as did the forest(China:0.035,accounting for 20.35%of 0.172;US:0.054,accounting for 28.27%of 0.191).Childhood health,financial status,and regional differences were key determinants of senior health.The conditional inference forest consistently outperformed others in predictive accuracy,as demonstrated by lower out-of-sample mean squared error(MSE).Discussion:The findings emphasize the need for early-life interventions to promote health equity in aging populations.Machine learning showcases the potential in identifying contributing factors.

Background:Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood.This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods:We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies.A healthy parental lifestyle score(ranged 0-5)was constructed based on the following five modifiable lifestyle factors:Smoking,drinking,exercise,sleep,and diet.Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years(2012,2014,2016,and 2018).Results:Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence(multivariable-adjusted β=0.53,95%confidence interval[CI]:0.29-0.77)and overall crystallized intelligence(multivariable-adjusted β=0.35,95%CI:0.16-0.54)than those in the bottom tertile of parental healthy lifestyle scores.The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status.Additionally,maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance,with significant contribution observed for paternal never-smoking,weekly exercise,and diversified diet.When both parents and offspring adhered to a healthier lifestyle,we observed the highest level of the offspring’s overall crystallized intelligence.Conclusions:Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood,regardless of socioeconomic status.These findings highlight the potential cognitive benefits of promoting healthy lif
