Background:The 2017 American College of Cardiology/American Heart Association(ACC/AHA)blood pressure(BP)guideline lowered the threshold defining hypertension to 130/80 mmHg.However,how stage 1 hypertension defined using this guideline is associated with cardiovascular events in Chinese adults remains unclear.This study assessed the association between stage 1 hypertension defined by the 2017 ACC/AHA guideline and clinical outcomes in the Chinese population.Methods:Participants with stage 1 hypertension(n=69,509)or normal BP(n=34,142)were followed in this study from 2006/2007 to 2020.Stage 1 hypertension was defined as a systolic blood pressure of 130-139 mmHg or a diastolic blood pressure of 80-89 mmHg.None were taking antihypertensive medication or had a history of myocardial infarction(MI),stroke,or cancer at baseline.The primary outcome was a composite of MI,stroke,and all-cause mortality.The secondary outcomes were individual components of the primary outcome.Cox proportional hazards models were used for the analysis.Results:During a median follow-up of 11.09 years,we observed 10,479 events(MI,n=995;stroke,n=3408;all-cause mortality,n=7094).After multivariable adjustment,the hazard ratios for stage 1 hypertension vs.normal BP were 1.20(95%confidence interval[CI],1.13-1.25)for primary outcome,1.24(95%CI,1.05-1.46)for MI,1.45(95%CI,1.33-1.59)for stroke,and 1.11(95%CI,1.04-1.17)for all-cause mortality.The hazard ratios for participants with stage 1 hypertension who were prescribed antihypertensive medications compared with those without antihypertensive treatment during the follow-up was 0.90(95%CI,0.85-0.96).Conclusions:Using the new definition,Chinese adults with untreated stage 1 hypertension are at higher risk for MI,stroke,and all-cause mortality.This finding may help to validate the new BP classification system in China.

Phenomenology of heavy neutral gauge boson at muon collider

Science China(Physics,Mechanics & Astronomy) 2024年第3期67卷 60-79页

作者： Zongyang Lu Honglei Li Zhi-Long Han Zong-Guo Si liuxin Zhao School of Physics and Technology University of JinanJinan 250022China School of Physics Shandong UniversityJinan 250100China

Heavy neutral gauge boson Z' is proposed in many new physics models.It has rich phenomena at the future muon collider.We study the properties of Z' boson with the process of μ^(+)μ^(-)→qq,μ^(+)μ^(-)→l^(+)l^(-),μ^(+)μ^(-)→ ZH and μ^(+)μ^(-)→ W^(+)W^(-).The discrepancy of Z' coupling to different types of particles can be shown in the cross section distributions around the resonance peak of various decay modes.Angular distributions of the final quark or lepton in μ^(+)μ^(-)→qq/l^(+)l^(-)process are sensitive to the parameters such as mass of Z' and the Z-Z' mixing angle.The interaction of new gauge boson coupling to the standard model gauge particles and Higgs boson are also studied through μ^(+)μ^(-)→ ZH→l^(+)l^(-)bb and μ^(+)u^(-)→ W^(+)W^(-)→l^(+)l^(-)v_(l)v_(l).The cross section and the final particles' angular distributions with the contribution of Z' boson differ from those processes with only standard model particles.A forward-backward asymmetry defined by the angular distribution is provided to show the potential of searching for new physics at the muon collider.Especially,the beam polarization with certain value can effectively enlarge the forward-backward asymmetry.

从德性与理性的关系来看,人类文明形态大体可以分为“德性文明”和“理性文明”两种类型。当代中国日生日成的中华民族现代文明,作为人类文明新形态,在根本特质上属于德性文明;从历史文化根脉来看,是数千年来生生不息的中华传统德性文明“旧邦新命”的新生面;从精神动力来看,来自于马克思主义与中华优秀传统文化的融通。人类文明新形态与中华传统德性文明在根本特质上古今一贯,在文化根脉和人文精神上源流相续,在中华民族共同体历史命运上一脉相承。然而,人类文明新形态并非简单“复活”或“复归”中华传统德性文明,而是造就“新的文化生命体”意义上的“文明更新”。人类文明新形态具有道义和真理双重意义上的人类新启蒙和新觉醒的力量,典范性地昭示着人类从理性文明向德性文明转型跃升的新方向。

The electrocatalytic nitrogen reduction reaction(NRR)has emerged as a promising renewable energy source and a feasible strategy as an alternative to Haber-Bosch ammonia(NH_(3))synthesis.However,finding an efficient and cost-effective robust catalyst to activate and cleave the extremely strong triple bond in nitrogen(N_(2))for electrocatalytic NRR is still a challenge.Herein,a FeNi@CNS nanocomposite as an efficient catalyst for N_(2) fixation under ambient conditions is designed.This FeNi@CNS nanocomposite was prepared by a simple water bath process and post-calcination.The FeNi@CNS is demonstrated to be a highly efficient NRR catalyst,which exhibits better NRR performance with exceptional Faradaic efficiency of 9.83%and an NH_(3) yield of 16.52μg h^(−1) cm^(−2) in 0.1 M Na_(2)SO_(4) aqueous solution.Besides,high stability and reproducibility with consecutive 6 cycles for two hours are also demonstrated throughout the NRR electrocatalytic process for 12 h.Meanwhile,the FeNi@CNS catalyst encourages N_(2) adsorption and activation as well as effectively suppressing competitive HER.Therefore,this earth-abundant FeNi@CNS catalyst with a subtle balance of activity and stability has excellent potential in NRR industrial applications.

Since the discovery of enzyme-like activity of Fe3O4 nanoparticles in 2007,nanozymes are becoming the promising substitutes for natural enzymes due to their advantages of high catalytic activity,low cost,mild reaction conditions,good stability,and suitable for large-scale production.Recently,with the cross fusion of nanomedicine and nanocatalysis,nanozyme-based theranostic strategies attract great attention,since the enzymatic reactions can be triggered in the tumor microenvironment to achieve good curative effect with substrate specificity and low side effects.Thus,various nanozymes have been developed and used for tumor therapy.In this review,more than 270 research articles are discussed systematically to present progress in the past five years.First,the discovery and development of nanozymes are summarized.Second,classification and catalytic mechanism of nanozymes are discussed.Third,activity prediction and rational design of nanozymes are focused by highlighting the methods of density functional theory,machine learning,biomimetic and chemical design.Then,synergistic theranostic strategy of nanozymes are introduced.Finally,current challenges and future prospects of nanozymes used for tumor theranostic are outlined,including selectivity,biosafety,repeatability and stability,in-depth catalytic mechanism,predicting and evaluating activities.

Fresh-Keeping Decision and Coordination of Fresh Agricultural Product Supply Chain Considering Carbon Cap-and-Trade under Different Dominance

引用

Journal of Systems Science and Systems Engineering 2024年第1期33卷 30-51页

作者： yang yang Guanxin Yao China Institute for Agricultural Equipment Industrial Development Jiangsu UniversityZhenjiang212013China Jiangsu Modern Logistics Research Base Yangzhou UniversityYangzhou225009China

In the context of low carbon,this paper discussed the impact of the carbon cap-and-trade policy on the fresh-keeping decision-making of two-echelon fresh agricultural product supply chains under different dominance,and designed cost-sharing contracts to coordinate the supply chain of fresh agricultural products dominated by suppliers and retailers respectively.The results showed that:dominance has no effect on the fresh-keeping decision and total revenue of fresh agricultural product supply chain,but it affects the internal income distribution,and dominance does not always bring more benefits;the implementation of carbon cap-and-trade reduces the fresh-keeping decision-making of fresh agricultural products supply chain and reduces the free-rider income of followers;the role of higher carbon trading price is twofold,which not only brings about the speculation of leading enterprises,but also promotes the application of low-carbon technologies;consumers’high preference for freshness,low-cost and high-efficiency low-carbon technology are all conducive to improving the fresh-keeping efforts and benefits of the supply chain;cost-sharing contracts can coordinate the supply chain of fresh agricultural products.

Acute myeloid leukemia(AML)is a rapidly lethal blood cancer characterized by aberrant proliferation and differentiation of myeloid progenitors in the hematopoietic tissue.In recent decades,AML patients are significantly increased.In 2019 alone,21,450 new AML cases were diagnosed in the United States,with an estimated 10,920 deaths due to AML.What’s worse,AML occurs with an increasing incidence with advanced age,and the survival rate remains dismal with a median overall survival of only 5e10 months.Notwithstanding great advances in allogenic transplant and chemotherapy,the therapeutic outcomes are unfavorable due to the disease relapse and mortality rates.More importantly,the development of more specific and effective therapies was hampered in part by the lack of proper animal models for AML.Thus,management and elucidation of the pathological mechanism of AML remain an ongoing challenge,and the development of effective AML mouse models and treatment options are urgently needed.
