| 2 | Significance of ultrasound evaluation of carotid atherosclerotic plaque for diagnosing ischemic cerebrovascular disease显示文摘BACKGROUND: Carotid artery is the main source for craniocerebral blood supply. Its intimal plaque formation and arterial stenosis degree both are the risk factors for ischemic cerebrovascular disease. Therefore, the close relationship of carotid atherosclerotic plaque and ischemic cerebrovascular disease, and ultrasound evaluation of carotid atherosclerotic plaque have become the hot spot in studying ischemic cerebrovascular disease. OBJECTIVE: This study was to detect the degree of carotid atherosclerosis of ischemic cerebrovascular disease patients by ultrasonography, and to analyze the situation of carotid atherosclerosis and its relationship with clinic. DESIGN: Clinical randomized concurrent control experiment. SETTING: Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA. PARTICIPANTS: Totally 60 outpatients and inpatients with ischemic cerebrovascular disease, 42 males and 18 females, admitted to Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA between January 2006 and December 2006 were involved in the patient group. They met the diagnosis criteria of ischemic cerebrovascular disease constituted by the 4th Cerebrovascular Disease Conference in 1996, and were confirmed to suffer from ischemic cerebrovascular disease by skull CT and MRI. Another 20 subjects who received healthy examination concurrently in the same hospital, 12 males and 8 females, were involved in the control group. Informed consents of detected items were obtained from involved subjects. METHODS: The plaque thickness of mid portion, distal end and crotch of common carotid artery (CCA), internal carotid artery (ICA), external carotid artery (ECA) and vertebral artery (VA) of involved subjects, who received health examination was separately detected with color Doppler ultrasonograph (HDI-5000). Then, total integral of plaque was calculated. The intima-media thickness (IMT) was measured with two-dimensional ultrasonography. The inner diameter stenosis degree of subjects who had plaque was measured. Blood flow parameters were recorded, and stenosis degree and plaque area were calculated. Blood flow volume of bilateral carotid artery and VA was separately measured with ultrasound equipment software, and brain blood flow volume was calculated. MAIN OUTCOME MEASURES: Atherosclerotic degree and blood flow volume of patients of two groups. RESULTS: Sixty patients with ischemic cerebrovascular disease and twenty subjects who received health examination participated in the final analysis. ①The IMT thickness, total plaque score, and total plaque area of patient group was significantly superior to that of control group, respectively(t=5.216–10.158,P < 0.05). ② There were significant differences in the stenosis degree of CCA, ICA and VA between patient group and control group (t=6.720–12.816,P < 0.05). ③ The blood flow volume of CCA, ICA, VA and brain of patient group was significantly lower than that of control group, respectively (t=2.872–10.860, P < 0.05). CONCLUSION: Ischemic cerebrovascular disease patients have different degrees of changes in atherosclerosis and arterial blood flow. | Li Gu Yaqin Feng Liwen Liu Liping Yang Lili He | 2007 | Neural Regeneration Research2007，2，7： | 7 |

| 4 | Flexible and stable 3D lithium metal anodes based on self-standing MXene/COF frameworks for high-performance lithium-sulfur batteries显示文摘Lithium metal(Li)is believed to be the ultimate anode for lithium-ion batteries(LIBs)owing to the advantages of high theoretical capacity,the lowest electrochemical potential,and light weight.Nevertheless,issues such as uncontrollable growth of Li dendrites,large volume changes,high chemical reactivity,and unstable solid electrolyte interphase(SEI)hinder its rapid development and practical application.Herein a stable and dendrite-free Li-metal anode is obtained by designing a flexible and freestanding MXene/COF framework for metallic Li.COF-LZU1 microspheres are distributed among the MXene film framework.Lithiophilic COF-LZU1 microspheres as nucleation seeds can promote uniform Li nucleation by homogenizing the Li^(+)flux and lowering the nucleation barrier,finally resulting in dense and dendrite-free Li deposition.Under the regulation of the COF-LZU1 seeds,the Coulombic efficiency of the MXene/COF-LZU1 framework and electrochemical stability of corresponding symmetric cells are obviously enhanced.Li-S full cells with the modified Li-metal anode and sulfurized polyacrylonitrile(S@PAN)cathode also exhibited a superior electrochemical performance. | Chuanliang Wei Yusheng Wang Yuchan Zhang Liwen Tan Yi Qian Yuan Tao Shenglin Xiong Jinkui Feng | 2021 | Nano Research2021，14，10： | 5 |

| 6 | Self-assembled, highly-lithiophilic and well-aligned biomass engineered MXene paper enables dendrite-free lithium metal anode in carbonate-based electrolyte显示文摘Lithium metal anode is the ideal candidate for high-energy–density rechargeable batteries.However,uncontrolled dendrite growth hampers its commercialization.Herein,a dendrite-free composite Li metal anode is realized by a flexible,freestanding,well-aligned and highly-lithiophilic MXene paper designed by a facile electrostatic self-assembly of the exfoliated MXene nanosheets and natural polysaccharidechitosan (MX@CS).The MX@CS paper gets a well-aligned layered-3D structure with a micro-crumpled surface that can effectively decrease the local current density,guide even Li plating and suppress dendritic Li growth.More importantly,surface-adsorbed chitosan endows enhanced lithiophilicity for MXene substrate and thus reduces the Li nucleation overpotential,which is confirmed by the density functional theory calculations.Abundant lithiophilic groups on MX@CS surface provide highconcentration Li^(+)anchoring site promoting Li nucleation and laterally inducing uniform Li deposition,which effectively avoids the formation of dendritic Li.As a result,the MX@CS-Li anode with a dendrite-free Li morphology shows a significantly improved cycling life in commercial carbonatebased electrolyte.When coupled with LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)cathode,the full cell exhibits a low capacity decay and steady ultrahigh Coulombic efficiency of 99.6%at a current density of 5C.These findings develop a new approach for designing high-performance metal-based rechargeable batteries. | Liwen Tan Chuanliang Wei Yuchan Zhang Shenglin Xiong Hui Li Jinkui Feng | 2022 | Journal of Energy Chemistry2022，31，6： | 4 |

| 9 | Room-temperature liquid metal engineered iron current collector enables stable and dendrite-free sodium metal batteries in carbonate electrolytes显示文摘Metallic sodium(Na)is believed to be a promising anode material for sodium-ion batteries(SIBs)due to its low electrochemical potential,high theoretical specific capacity,superior electrical conductivity,and so on.However,issues such as high chemical activity,the growth of Na dendrites,large volume change,and unstable interface impede its practical application.We design a cheap iron(Fe)-based substrate decorated by a thin liquid metal Ga layer for stable and dendrite-free Na metal anodes in low-cost carbonate electrolytes.The inherent mechanism of Ga-based liquid metal in inhibiting the growth of Na dendrites was revealed for the first time.Liquid metal Ga with sodiophilic property can act as nucleation seeds to decrease the nucleation barrier and induce homogeneous Na+flux,resulting in uniform and dendrite-free Na deposition.Full cells with Na_(3)V_(2)(PO_(4))_(3) cathode were also assembled to verify the practical application ability of the modified Na metal anode.Under the regulation of the liquid metal layer,the Coulombic efficiency,cycling life,and capacity of batteries are obviously enhanced.The strategy proposed here cannot only reduce the cost of batteries but also improve their electrochemical and safety performance. | Chuanliang Wei Liwen Tan Yuchan Zhang Huiyu Jiang Baojuan Xi Shenglin Xiong Jinkui Feng | 2022 | Journal of Materials Science & Technology2022，，20： | 1 |
| 10 | An Efficient SCF-PEKS Without Random Oracle Under Simple Assumption显示文摘The Public key encryption scheme with keyword search(PEKS),firstly put forward by Boneh et al.,can achieve the keyword searching without revealing any information of the initial data.However,the original PEKS scheme was required to construct a secure channel,which was usually expensive.Aimed at resolving this problem,Baek et al.put forward an improved scheme,which tried to construct a Secure channel free PEKS(SCFPEKS).Subsequently,several SCF-PEKS schemes were proposed,however most of them turned out only secure in the random oracle model,which possibly lead to the construction of insecure schemes.Therefore,Fang et al.put forward an enhanced SCF-PEKS construction,which was provably secure in the standard model,however this construction needed a strong and complicated assumption.Then Yang et al.put forward an SCF-PEKS construction under simple assumption,but their construction had a big reduction in efficiency.In this article,we propose an SCFPEKS construction,which is provably secure under the same assumption as that of Yang et al.’s scheme,however,with better performance.Then we give its full security proof,along with the performance analysis.Finally,we improve the SCF-PEKS construction to resist Keyword guessing attack(KGA)and give its security demonstration. | WANG Guangbo LI Feng FAN Liwen LIU Haicheng | 2021 | Chinese Journal of Electronics2021，30，1： | 1 |

| 13 | Metal-organic frameworks and their derivatives in stable Zn metal anodes for aqueous Zn-ion batteries显示文摘Zn metal anode is believed to be a promising anode material for aqueous Zn-ion batteries(ZIBs)due to the mer-its such as low electrochemical potential,low cost,high theoretical specific capacity,high hydrogen evolution overpotential,less-reactive property,environmental friendliness and easy processing.However,issues including uncontrollable growth of Zn dendrites,corrosion by aqueous electrolyte,large volume change and unstable in-terface hinder its further development.Recently,multifunctional metal-organic frameworks(MOFs)and their derivatives have shown huge advantages in solving the issues facing Zn metal anode,and large advances have been achieved.MOFs and their derivatives can stabilize Zn metal anode by interface engineering,designing host,decorating separator,constructing solid-state electrolyte and so on.Here we carefully summarize and analyse these advances.Meanwhile,some perspectives and outlooks are put forward.This review can promote the de-velopment of MOFs,Zn metal anode as well as aqueous ZIBs. | Chuanliang Wei Liwen Tan Yuchan Zhang Shenglin Xiong Jinkui Feng | 2022 | ChemPhysMater2022，1，4： | 1 |

| 16 | Directed evolution of a neutrophilic and mesophilic methanol dehydrogenase based on high-throughput and accurate measurement of formaldehyde显示文摘Methanol is a promising one-carbon feedstock for biomanufacturing,which can be sustainably produced from carbon dioxide and natural gas.However,the efficiency of methanol bioconversion is limited by the poor catalytic properties of nicotinamide adenine dinucleotide(NAD^(+))-dependent methanol dehydrogenase(Mdh)that oxidizes methanol to formaldehyde.Herein,the neutrophilic and mesophilic NAD^(+)-dependent Mdh from Bacillus stearothermophilus DSM 2334(Mdh_(Bs))was subjected to directed evolution for enhancing the catalytic activity.The combination of formaldehyde biosensor and Nash assay allowed high-throughput and accurate measurement of formaldehyde and facilitated efficient selection of desired variants.Mdh_(Bs)variants with up to 6.5-fold higher K_(cat)/K_(M)value for methanol were screened from random mutation libraries.The T153 residue that is spatially proximal to the substrate binding pocket has significant influence on enzyme activity.The beneficial T153P mutation changes the interaction network of this residue and breaks theα-helix important for substrate binding into two shortα-helices.Reconstructing the interaction network of T153 with surrounding residues may represent a promising strategy to further improve Mdh_(Bs),and this study provides an efficient strategy for directed evolution of Mdh. | Jin Qian Liwen Fan Jinxing Yang Jinhui Feng Ning Gao Guimin Cheng Wei Pu Wenjuan Zhou Tao Cai Shuang Li Ping Zheng Jibin Sun Depei Wang Yu Wang | 2023 | Synthetic and Systems Biotechnology2023，8，3： | 0 |
| 17 | Clinical characteristics and vaccine effectiveness against SARS-CoV-2 Omicron subvariant BA.2 in the children显示文摘Dear Editor,The Omicron variant of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has rapidly replaced the Delta variant as a dominating SARS-CoV-2 variant because of natural selection,which favors the variant with higher infectivity and stronger vaccine breakthrough ability.1 Among three lineages BA.1(B.1.1.529.1),BA.2(B.1.1.529.2),and BA.3(B.1.1.529.3)of Omicron,BA.2 is rising rapidly worldwide since January 2022 and become a new dominating“variant of concern”in China.2 With the current surge in Omicron in China,both the absolute number of children hospitalized with COVID-19 and the percentage of total COVID-19 hospitalizations have been boosting recently.Understanding the clinical characteristics of SARS-CoV-2 Omicron subvariant BA.2 in children and the protective effect of vaccines is of great help for epidemic prevention strategies.However,so far no sufficient experimental data have been reported about infectivity,disease severity,vaccine breakthrough capability,and antibody resistance from pediatric BA.2. | Xiaohe Li Liwen Wu Youzhi Qu Mengli Cao Jiaqi Feng Hua Huang Yi Liu Hongzhou Lu Quanying Liu Yingxia Liu | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 0 |
| 18 | New class of high-entropy pseudobrookite titanate with excellent thermal stability,low thermal expansion coefficient,and low thermal conductivity显示文摘As a type of titanate,the pseudobrookite(MTi_(2)O_(5)/M_(2)TiO_(5))exhibits a low thermal expansion coefficient and thermal conductivity,as well as excellent dielectric and solar spectrum absorption properties.However,the pseudobrookite is unstable and prone to decomposing below 1200℃,which limits the practical application of the pseudobrookite.In this paper,the high-entropy pseudobrookite ceramic is synthesized for the first time.The pure high-entropy(Mg,Co,Ni,Zn)Ti_(2)O_(5) with the pseudobrookite structure and the biphasic high-entropy ceramic composed of the highentropy pseudobrookite(Cr,Mn,Fe,Al,Ga)_(2)TiO_(5) and the high-entropy spinel(Cr,Mn,Fe,Al,Ga,Ti)_(3)O_(4) are successfully prepared by the in-situ solid-phase reaction method.The comparison between the theoretical crystal structure of the pseudobrookite and the aberration-corrected scanning transmission electron microscopy(AC-STEM)images of high-entropy(Mg,Co,Ni,Zn)Ti_(2)O_(5) shows that the metal ions(M and Ti ions)are disorderly distributed at the A site and the B site in high-entropy(Mg,Co,Ni,Zn)Ti_(2)O_(5),leading to an unprecedentedly high configurational entropy of high-entropy(Mg,Co,Ni,Zn)Ti_(2)O_(5).The bulk high-entropy(Mg,Co,Ni,Zn)Ti_(2)O_(5) ceramics exhibit a low thermal expansion coefficient of 6.35×10^(−6) K^(−1) in the temperature range of 25-1400℃ and thermal conductivity of 1.840 W·m^(−1)·K^(−1) at room temperature,as well as the excellent thermal stability at 200,600,and 1400℃.Owing to these outstanding properties,high-entropy(Mg,Co,Ni,Zn)Ti_(2)O_(5) is expected to be the promising candidate for high-temperature thermal insulation.This work has further extended the family of different crystal structures of high-entropy ceramics reported to date. | Jinyu WU Xiaohui MA Xiaoxia HU Liwen YAN Feng HOU Jiachen LIU Anran GUO | 2022 | Journal of Advanced Ceramics2022，11，10： | 0 |
| 19 | The thylakoid membrane protein NTA1 is an assembly factor of the cytochrome b6f complex essential for chloroplast development in Arabidopsis显示文摘The cytochrome b_(6f)(Cyt b_(6f))complex is a multisubunit protein complex in chloroplast thylakoid membranes required for photosynthetic electron transport.Here we report the isolation and characterization of the new tiny albino 1(nta1)mutant in Arabidopsis,which has severe defects in Cyt b_(6f) accumulation and chloroplast development.Gene cloning revealed that the nta1 phenotype was caused by disruption of a single nuclear gene,NTA1,which encodes an integral thylakoid membrane protein conserved across green algae and plants.Overexpression of NTA1 completely rescued the nta1 phenotype,and knockout of NTA1 in wild-type plants recapitulated the mutant phenotype.Loss of NTA1 function severely impaired the accumulation of multiprotein complexes related to photosynthesis in thylakoid membranes,particularly the components of Cyt b_(6f).NTA1 was shown to directly interact with four subunits(Cyt b6/PetB,PetD,PetG,and PetN)of Cyt b_(6f) through the DUF1279 domain and C-terminal sequence to mediate their assembly.Taken together,our results identify NTA1 as a new and key regulator of chloroplast development that plays essential roles in assembly of the Cyt b_(6f) complex by interacting with multiple Cyt b_(6f) subunits. | Na Li Wing Shing Wong Lei Feng Chunming Wang King Shing Wong Nianhui Zhang Wei Yang Yueming Jiang Liwen Jiang Jun-Xian He | 2023 | Plant Communications2023，4，1： | 0 |
