| 3 | Schisandra sphenanthera extract(Wuzhi Tablet)protects against chronic-binge and acute alcohol-induced liver injury by regulating the NRF2-ARE pathway in mice显示文摘Alcohol abuse leads to alcoholic liver disease and no effective therapy is currently available.Wuzhi Tablet(WZ), a preparation of extract from Schisandra sphenanthera that is a traditional hepatoprotective herb, exerted a significant protective effect against acetaminophen-induced liver injury in our recent studies, but whether WZ can alleviate alcohol-induced toxicity remains unclear. This study aimed to investigate the contribution of WZ to alcohol-induced liver injury by using chronic-binge and acute models of alcohol feeding. The activities of ALT and AST in serum were assessed as well as the level of GSH and the activity of SOD in the liver. The expression of CYP2E1 and proteins in the NRF2-ARE signaling pathway including NRF2, GCLC, GCLM, HO-1 were measured, and the effect of WZ on NRF2 transcriptional activity was determined. We found that both models resulted in liver steatosis accompanied by increased transaminase activities, but that liver injury was significantly attenuated by WZ. WZ administration also inhibited CYP2E1 expression induced by alcohol, and elevated the level of GSH and the activity of SOD in the liver. Moreover, the NRF2-ARE signaling pathway was activated by WZ andthe target genes were all upregulated. Furthermore, WZ significantly activated NRF2 transcriptional activity. Collectively, our study demonstrates that WZ protected against alcohol-induced liver injury by reducing oxidative stress and improving antioxidant defense, possibly by activating the NRF2-ARE pathway. | Xuezhen Zeng Xi Li Chenshu Xu Fulin Jiang Yufei Mo Xiaomei Fan Yaoting Li Yiming Jiang Dongshun Li Min Huang Huichang Bi | 2017 | Acta Pharmaceutica Sinica B2017，7，5： | 13 |
| 4 | Catalyst design strategies towards highly shape-selective HZSM-5 for paraxylene through toluene alkylation显示文摘With the shape selective zeolite catalyst,toluene alkylation with methanol to para-xylene(MTPX)technology could produce highly pure para-xylene(PX)in one step.The lower feedstock cost and less energy consumption in products separation make it more competitive compared to the current toluene disproportionation route.Thus,MTPX is regarded as the most reasonable production route for PX production.This article reviews the strategies that applied to the preparation of high-performance catalysts for MTPX,with special focus on the precise control of pore dimension and acid sites distribution in zeolite to achieve the highest selectivity to PX.The outlook of the MTPX catalyst is also proposed to guide the catalyst development in the field. | Xin Huang Ruizhuang Wang Xu Pan Chuanfu Wang Maohong Fan Yufei Zhu Yonggang Wang Jin Peng | 2020 | Green Energy & Environment2020，5，4： | 10 |

| 6 | Adaptive sliding mode backstepping control for near space vehicles considering engine faults显示文摘A fault tolerant control methodology based adaptive sliding mode(ASM) backstepping is proposed for near space vehicle(NSV) attitude control system under engine faults. The proposed scheme combined adaptive backstepping with the sliding mode control strategy could guarantee the system's stability and track desired signals under external disturbances and engine faults. Firstly, attitude mode description and the engine faulty model are given. Secondly, a nominal control law is designed.Thirdly, a sliding mode observer is given later in order to estimate both the information of engine faults and external disturbances. An adaptive sliding mode technology based on the previous nominal control law is developed via updating faulty parameters. Finally,analyze the system's fault-tolerant performance and reliability through experiment simulation, which verifies the proposed design of fault-tolerant control can tolerate engine faults, as well as the strong robustness for external disturbance. | ZHAO Jing JIANG Bin XIE Fei GAO Zhifeng XU Yufei | 2018 | Journal of Systems Engineering and Electronics2018，29，2： | 5 |
| 7 | Tuning the selectivity of photoreduction of CO2 to syngas over Pd/layered double hydroxide nanosheets under visible light up to 600 nm显示文摘Photocatalytic reduction of CO2 with H2 O to syngas is an effective way for producing high value-added chemical feedstocks such as methanol and light olefins in industry.Nevertheless,the precise control of CO/H2 ratio from photocatalytic CO2 reduction reaction still poses a great challenge for the further application.Herein,we prepared a series of highly efficient heterostructure based on highly dispersed palladium supported on ultrathin Co Al-layered double hydroxide(LDH).In conjunction with a Ru-complex sensitizer,the molar ratios of CO/H2 can be tuned from 1:0.74 to 1:3 under visible-light irradiation(λ>400 nm).More interestingly,the syngas can be obtained under light irradiation atλ>600 nm.Structure characterization and density functional theory calculations revealed that the remarkable catalytic activity can be due to the supported palladium,which improved the charge transfer efficiency.Meanwhile,more H atoms were used to generate H2 on the supported palladium for further tunable CO/H2 ratio.This work demonstrates a new strategy for harnessing abundant solar-energy to produce syngas from a CO2 feedstock. | Xian Wang Zelin Wang Ya Bai Ling Tan Yanqi Xu Xiaojie Hao Jikang Wang Abdul Hanif Mahadi Yufei Zhao Lirong Zheng Yu-Fei Song | 2020 | Journal of Energy Chemistry2020，29，7： | 5 |
| 8 | Remarkable carbon dioxide catalytic capture (CDCC) leading to solid-form carbon material via a new CVD integrated process (CVD-IP): An alternative route for CO_2 sequestration显示文摘Through our newly-developed 'chemical vapor deposition integrated process (CVD-IP)' using carbon dioxide (CO2) as the raw material and only carbon source introduced, CO2 could be catalytically activated and converted to a new solid-form product, i.e., carbon nanotubes (CO2-derived) at a quite high yield (the single-pass carbon yield in the solid-form carbon-product produced from CO2 catalytic capture and conversion was more than 30% at a single-pass carbon-base). For comparison, when only pure carbon dioxide was introduced using the conventional CVD method without integrated process, no solid-form carbon-material product could be formed. In the addition of saturated steam at room temperature in the feed for CVD, there were much more end-opening carbon nano-tubes produced, at a slightly higher carbon yield. These inspiring works opened a remarkable and alternative new approach for carbon dioxide catalytic capture to solid-form product, comparing with that of CO2 sequestration (CCS) or CO2 mineralization (solidification), etc. As a result, there was much less body volume and almost no greenhouse effect for this solid-form carbon-material than those of primitive carbon dioxide. | Wei Chu Maofei Ran Xu Zhang Ning Wang Yufei Wang Heping Xie Xiusong Zhao | 2013 | Journal of Energy Chemistry2013，22，1： | 5 |
| 9 | Niacin alters the ruminal microbial composition of cattle under high-concentrate condition显示文摘To understand the effects of niacin on the ruminal microbial ecology of cattle under high-concentrate diet condition, Illumina MiSeq sequencing technology was used. Three cattle with rumen cannula were used in a 3 x 3 Latin-square design trial. Three diets were fed to these cattle during 3 periods for 3 days, respectively: high-forage diet(HF; forage-to-concentrate ratio = 80:20), high-concentrate diet(HC;forage-to-concentrate ratio=20:80), and HC supplemented with 800 mg/kg niacin(HCN). Ruminal pH was measured before feeding and every 2 h after initiating feeding. Ruminal fluid was sampled at the end of each period for microbial DNA extraction. Overall, our findings revealed that subacute ruminal acidosis(SARA) was induced and the a-diversity of ruminal bacterial community decreased in the cattle of HC group. Adding niacin in HC could relieve the symptoms of SARA in the cattle but the ruminal pH value and the Shannon index of ruminal bacterial community of HCN group were still lower than those of HF group. Whatever the diet was, the ruminal bacterial community of cattle was dominated by Bacteroidetes,Firmicutes and Proteobacteria. High-concentrate diet significantly increased the abundance of Prevotella,and decreased the abundance of Paraprevotella, Sporobacter, Ruminococcus and Treponema than HF.Compared with HC, HCN had a trend to decrease the percentage of Prevotella, and to increase the abundance of Succiniclasticum, Acetivibrio and Treponema. Increasing concentrate ratio could decrease ruminal pH value, and change the ruminal microbial composition. Adding niacin in HC could increase the ruminal pH value, alter the ruminal microbial composition. | Dan Luo Yufei Gao Youyou Lu Mingren Qu Xiaowen Xiong Lanjiao Xu Xianghui Zhao Ke Pan Kehui Ouyang | 2017 | Animal Nutrition2017，，2： | 4 |
| 10 | Mechanistic and therapeutic perspectives for cardiac arrhythmias:beyond ion channels显示文摘Cardiac arrhythmias are among the most common causes of death in the world. Foundational studies established the critical role of ion channel disorders in arrhythmias, yet defects in ion channels themselves, such as mutations, may not account for all arrhythmias. Despite the progress made in recent decades, the antiarrhythmic drugs currently available have limited effectiveness,and the majority of these drugs can have proarrhythmic effects. This review describes novel knowledge on cellular mechanisms that cause cardiac arrhythmias, focuses on the dysfunction of subcellular organelles and intracellular logistics, and discusses potential strategies and challenges for developing novel, safe and effective treatments for arrhythmias. | Yufei Wu Jun Li Liang Xu Li Lin Yi-Han Chen | 2017 | Science China(Life Sciences)2017，60，4： | 4 |

| 12 | Slightly ruthenium doping enables better alloy nanoparticle exsolution of perovskite anode for high-performance direct-ammonia solid oxide fuel cells显示文摘Fuel flexibility is one of the most distinguished advantages of solid oxide fuel cells(SOFCs)over other low-temperature fuel cells.Furthermore,the combination of ammonia fuel and SOFCs technology should be a promising clean energy system after considering the high energy density,easy transportation/storage,matured synthesis technology and carbon-free nature of NH_(3) as well as high efficiency of SOFCs.However,the large-scale applications of direct-ammonia SOFCs(DASOFCs)are strongly limited by the inferior anti-sintering capability and catalytic activity for ammonia decomposition reaction of conventional nickel-based cermet anode.Herein,a slightly ruthenium(Ru)doping in perovskite oxides is proposed to promote the alloy nanoparticle exsolution,enabling better DA-SOFCs with enhanced power outputs and operational stability.After treating Ru-doped Pr_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.75)Ru_(0.05)O_(3-δ) single-phase perovskite in a reducing atmosphere,in addition to the formation of two layered Ruddlesden-Popper perovskites and Pr_(2)O_(3) nanoparticles(the same as the Ru-free counterpart,Pr_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)),the exsolution of CoFeRu-based alloy nanoparticles is remarkably promoted.Such reduced Pr_(0.6)Sr0.4Co_(0.2)Fe_(0.75)Ru_(0.05)O_(3-δ) composite anode shows superior catalytic activity and stability for NH_(3) decomposition reaction as well as anti-sintering capability in DA-SOFCs to those of reduced Pr0.6Sr0.4Co0.2Fe0.8O_(3-δ)due to the facilitated nanoparticle exsolution and stronger nanoparticle/substrate interaction.This work provides a facile and effective strategy to design highly active and durable anodes for DA-SOFCs,promoting large-scale applications of this technology. | Xiandong Xiong Jian Yu Xiaojian Huang Dan Zou Yufei Song Meigui Xu Ran Ran Wei Wang Wei Zhou Zongping Shao | 2022 | Journal of Materials Science & Technology2022，，30： | 3 |
| 13 | Effectiveness of moxibustion alone on lumbar disc herniation:a Meta-analysis of randomized controlled trials显示文摘OBJECTIVE:To evaluate the available evidence from randomized controlled trials(RCTs)of moxibustion alone for lumbar disc herniation(LDH)treatment.METHODS:A systematic search of 10 databases(until August 30,2021)was used to identify studies that reported the response rate,visual analogue scale(VAS)score,Japanese Orthopedic Association(JOA)score,and Oswestry Disability Index(ODI)score.Study selection and data extraction were independently performed by two reviewers.Cochrane criteria for risk of bias were used to assess the methodological quality of the trials.The Grading of Recommendations Assessment,Development,and Evaluation Methodology(GRADE)were also used to test the quality of the result evidence.RESULTS:Nineteen RCTs,including 1888 patients,met the inclusion criteria.Five studies showed no difference between moxibustion and acupuncture on response rate[risk ratio(RR)=1.07,95%CI(0.98,1.16),P=0.11].Meanwhile,six studies suggested that there is no significant difference between moxibustion and acupuncture on VAS score[mean difference(MD)=-0.43,95%CI(-0.91,0.05),P=0.08].Eight studies implied that there is no significant difference between moxibustion and acupuncture on JOA score[MD=0.84,95%CI(-1.27,2.96),P=0.44].Two studies indicated that moxibustion may have equivalent effects for treating LDH in the VAS score in comparison with drug therapy[MD=-1.16,95%CI(-2.63,0.31),P=0.12].The evidence level of results was determined to be very low to low.CONCLUSIONS:Based on the existing evidence,moxibustion may not be suitable for treating LDH alone,but it may be applied as an adjuvant treatment.Furthermore,well-designed RCTs with high quality and larger samples are still needed to evaluate the efficacy and safety of moxibustion alone for LDH treatment. | YAO Yao ZHAO Zhenni CHEN Fengqin LENG Yufei PANG Xiangtian XU Xiao SUN Zhiling | 2023 | Journal of Traditional Chinese Medicine2023，43，1： | 3 |

| 15 | China Antihypertensive Trial in Acute Ischemic Stroke II (CATIS-2): rationale and design显示文摘Backgrounds Increased blood pressure(BP)for patients who had an acute ischaemic stroke is associated with poor functional outcome,however the optimal timing of antihypertensive therapy is unknown.Aims We aim to compare early antihypertensive treatment to delayed antihypertensive treatment for reducing the risk of composite major disability and mortality at 3 months in acute ischaemic stroke.Design The China Antihypertensive Trial in Acute Ischemic Stroke II(CATIS-2)trial is a multicentre,randomised,open-label,blinded-endpoints trial that will be conducted in 100 hospitals in China.The primary outcome is the composite of death and major disability(modified Rankin Scale score≥3)at 3 months of randomisation.Antihypertensive treatment will be received immediately after randomisation in the early treatment group,aimed at average systolic BP by 10%-20%reduction within the first 24 hours,and achieving an average BP level of<140/90 mm Hg within 5 days.Patients in the delayed treatment group will discontinue any antihypertension medications for the first 7 days of randomisation,and will receive antihypertensive therapy achieving a BP goal of<140/90 mm Hg after 7 days.Conclusion The CATIS-2 trial will be testing the hypotheses that early BP lowering leads to improved functional outcome without any other harms,and developing clinical guidelines of the BP management for patients who had an acute ischaemic stroke. | Liping Liu Yilong Wang Xuewei Xie Dacheng Liu Aili Wang Penglian Wang Suwen Shen Chongke Zhong Yufei Wei Tan Xu Yuesong Pan Yong Jiang Xia Meng David Wang Yonghong Zhang Jiang He Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 3 |
| 16 | Comparison of inorganic chemical compositions of atmospheric TSP,PM10 and PM2.5 in northern and southern Chinese coastal cities显示文摘To compare the inorganic chemical compositions of TSP(total suspended paniculate),PM_(10)(particulate matter with an aerodynamic diameter less than 10 μm) and PM_(2.5)(particulate matter with an aerodynamic diameter less than 2.5 μm) in southern and northern cities in China,atmospheric particles were synchronously collected in Dalian(the northern city)and Xiamen(the southern city) in spring and autumn of 2004.The mass concentrations,twenty-three elements and nine soluble ions were assessed.The results show that in Dalian,the mass concentrations of Mg,Al,Ca,Mn and Fe in spring were 4.0-10.1,2.6-8.0,4.1-12,1.2-3.6 and 2.9-7.9 times higher,respectively,than those in Xiamen.The dust storm influence is more obvious in Dalian in spring.However,in Xiamen,heavy metals accounted for 13.9%-17.9%of TSP,while heavy metals contributed to 5.5%-9.3%of TSP in Dalian.These concentrations suggest that heavy metal pollution in Xiamen was more serious.In addition,the concentrations of Na^+,Cl^-,Ca^(2+) and Mg^(2+) were higher in Dalian due to the influence of marine aerosol,construction activities and soil dust.The NO^(3-)/SO_4^(2-) ratios in Dalian(0.25-0.49) were lower than those in Xiamen(0.51-0.62),indicating that the contributions of vehicle emission to particles in Xiamen were higher.Coefficient of divergence values was higher than 0.40,implying that the inorganic chemical composition profiles for the particles of Dalian and Xiamen were quite different from each other. | Yiding Ma Zongshuang Wang Yufei Tan Shu Xu Shaofei Kong Gang Wu Xuefang Wu Hong Li | 2017 | Journal of Environmental Sciences2017，29，5： | 2 |
| 17 | Discovery of carbon-based strongest and hardest amorphous material显示文摘Carbon is one of the most fascinating elements due to its structurally diverse allo tropic forms stemming from its bonding varieties(sp,sp^(2)and sp^(3)).Exploring new forms of carbon has been the eternal theme of scientific research.Herein,we report on amorphous(AM) carbon materials with a high fraction of sp^(3)bonding recovered from compression of fullerene C_(60) under high pressure and high temperature,previously unexplored.Analysis of photoluminescence and absorption spectra demonstrates that they are semiconducting with a bandgap range of 1.5-2.2 eV,comparable to that of widely used AM silicon.Comprehensive mechanical tests demonstrate that synthesized AM-Ⅲ carbon is the hardest and strongest AM material known to date,and can scratch diamond crystal and approach its strength.The produced AM carbon materials combine outstanding mechanical and electronic properties,and may potentially be used in photovoltaic applications that require ultrahigh strength and wear resistance. | Shuangshuang Zhang Zihe Li Kun Luo Julong He Yufei Gao Alexander V.Soldatov Vicente Benavides Kaiyuan Shi Anmin Nie Bin Zhang Wentao Hu Mengdong Ma Yong Liu Bin Wen Guoying Gao Bing Liu Yang Zhang Yu Shu Dongli Yu Xiang-Feng Zhou Zhisheng Zhao Bo Xu Lei Su Guoqiang Yang Olga P.Chernogorova Yongjun Tian | 2022 | National Science Review2022，9，1： | 2 |
| 18 | Cartilage oligomeric matrix protein is an endogenous β-arrestin-2-selective allosteric modulator of AT1 receptor counteracting vascular injury显示文摘Compelling evidence has revealed that biased activation of G protein-coupled receptor(GPCR)signaling,including angiotensin II(AngII)receptor type 1(AT1)signaling,plays pivotal roles in vascular homeostasis and injury,but whether a clinically relevant endogenous biased antagonism of AT1 signaling exists under physiological and pathophysiological conditions has not been clearly elucidated.Here,we show that an extracellular matrix protein,cartilage oligomeric matrix protein(COMP),acts as an endogenous allosteric biased modulator of the AT1 receptor and its deficiency is clinically associated with abdominal aortic aneurysm(AAA)development.COMP directly interacts with the extracellular N-terminus of the AT1 via its EGF domain and inhibits AT1-β-arrestin-2 signaling,but not Gq or Gi signaling,in a selective manner through allosteric regulation of AT1 intracellular conformational states.COMP deficiency results in activation of AT1a-β-arrestin-2 signaling and subsequent exclusive AAA formation in response to AngII infusion.AAAs in COMP–/–or ApoE–/–mice are rescued by AT1a orβ-arrestin-2 deficiency,or the application of a peptidomimetic mimicking the AT1-binding motif of COMP.Explorations of the endogenous biased antagonism of AT1 receptor or other GPCRs may reveal novel therapeutic strategies for cardiovascular diseases. | Yi Fu Yaqian Huang Zhao Yang Yufei Chen Jingang Zheng Chenfeng Mao Zhiqing Li Zhixin Liu Bing Yu Tuoyi Li Meili Wang Chanjuan Xu Yiwei Zhou Guizhen Zhao Yiting Jia Wei Guo Xin Jia Tao Zhang Li Li Ziyi Liu Shengchao Guo Mingliang Ma Heng Zhang Bo Liu Junbao Du Wengong Wang Chaoshu Tang Pei Gao Qingbo Xu Xian Wang Jianfeng Liu Jinpeng Sun Wei Kong | 2021 | Cell Research2021，31，7： | 2 |
| 19 | Multimodel-based flight control system reconfiguration control in the presence of input constraints显示文摘In this paper,an active fault accommodate strategy is proposed for the plant in the presence of actuator fault and input constraints,which is a combination of a direct adaptive control algorithm with multiple model switching.The μ-modification is introduced in the model reference architecture to construct the adaptive controller.The proof of stability is based on the candidate Lyapunov function,while appropriate switching of multiple models guarantees asymptotic tracking of the system states and the boundedness of all signals.Simulation results illustrate the efficiency of the proposed method. | Yuying GUO Bin JIANG Yufei XU | 2010 | 控制理论与应用(英文版)2010，8，4： | 2 |
| 20 | Constant temperature control of tundish induction heating power supply for metallurgical manufacturing显示文摘The tundish induction heating power supply(TIHPS)is one of the most important equipment in the continuous casting process for metallurgical manufacturing.Specially,the constant temperature control is greatly significant for metallurgical manufacturing.In terms of the relationship between TIH load temperature and output power of TIHPS,the constant temperature control can be realized by power control.In this paper,a TIHPS structure with three-phase PWM rectifiers and full-bridge cascaded inverter is proposed.Besides,an input harmonic current blocking strategy and a load voltage feedforward control are also proposed to realize constant temperature control.To meet the requirement of the system,controller parameters are designed properly.Experiments are con?ducted to validate the feasibility and effectiveness of the proposed TIHPS topology and the control methods. | Yufei YUE Qianming XU Peng GUO An LUO | 2019 | Frontiers in Energy2019，13，1： | 2 |
