| 1 | Single-cell RNA sequencing reveals B cell-T cell interactions in vascular adventitia of hyperhomocysteinemia-accelerated atherosclerosis显示文摘Dear Editor Cardiovascular disease(CVD)is the leading cause of death around the world(Truelsen,et al.,2015).Atherosclerosis,the dominant underlying cause of CVD,is a chronic inflam-matory disease characterized by lipid accumulation and immune cell infiltration in plaques and vessels(Weber,et al.,1950).The immune microenvironment is critical for the development of atherosclerosis.Homocysteine(Hcy)is an intermediate product of methionine metabolism,and its ele-vation in plasma(>15μmol/L),known as hyperhomocys-teinemia(HHcy),is an independent risk factor for atherosclerosis.HHcy is more common in Asia because of genetic factors and dietary habits(Huo,et al.,2015).folic acid supplement is one of the most important way to treat HHcy in clinic.Although HHcy potentiates atherosclerosis mainly through endothelial injury and inflammatory activa-tion(Luo,et al.,2016),a comprehensive understanding of the immune microenvironment and potential mechanisms in HHcy-accelerated atherosclerotic aortas(HHcy-AA)is still lacking. | Xiaolong Ma Jiacheng Deng Lulu Han Yuwei Song Yutong Miao Xing Du Guohui Dang Dongmin Yang Bitao Zhong Changtao Jiang Wei Kong Qingbo Xu Juan Feng Xian Wang | 2022 | Protein & Cell2022，13，7： | 2 |
| 2 | B cell-derived anti-beta 2 glycoprotein I antibody mediates hyperhomocysteinemia-aggravated hypertensive glomerular lesions by triggering ferroptosis显示文摘Hyperhomocysteinemia(HHcy)is a risk factor for chronic kidney diseases(CKDs)that affects about 85%CKD patients.HHcy stimulates B cells to secrete pathological antibodies,although it is unknown whether this pathway mediates kidney injury.In HHcytreated 2-kidney,1-clip(2K1C)hypertensive murine model,HHcy-activated B cells secreted anti-beta 2 glycoprotein I(β2GPI)antibodies that deposited in glomerular endothelial cells(GECs),exacerbating glomerulosclerosis and reducing renal function.Mechanistically,HHcy 2K1C mice increased phosphatidylethanolamine(PE)(18:0/20:4,18:0/22:6,16:0/20:4)in kidney tissue,as determined by lipidomics.GECs oxidative lipidomics validated the increase of oxidized phospholipids upon Hcy-activated B cells culture medium(Hcy-B CM)treatment,including PE(18:0/20:4+3[O],PE(18:0a/22:4+1[O],PE(18:0/22:4+2[O]and PE(18:0/22:4+3[O]).PE synthases ethanolamine kinase 2(etnk2)and ethanolamine-phosphate cytidylyltransferase 2(pcyt2)were increased in the kidney GECs of HHcy 2K1C mice and facilitated polyunsaturated PE synthesis to act as lipid peroxidation substrates.In HHcy 2K1C mice and Hcy-B CM-treated GECs,the oxidative environment induced by iron accumulation and the insufficient clearance of lipid peroxides caused by transferrin receptor(TFR)elevation and down-regulation of SLC7A11/glutathione peroxidase 4(GPX4)contributed to GECs ferroptosis of the kidneys.In vivo,pharmacological depletion of B cells or inhibition of ferroptosis mitigated the HHcy-aggravated hypertensive renal injury.Consequently,our findings uncovered a novel mechanism by which B cell-derived pathogenic anti-β2GPI IgG generated by HHcy exacerbated hypertensive kidney damage by inducing GECs ferroptosis.Targeting B cells or ferroptosis may be viable therapeutic strategies for ameliorating lipid peroxidative renal injury in HHcy patients with hypertensive nephropathy. | Xing Du Xiaolong Ma Ying Tan Fangyu Shao Chun Li Yang Zhao Yutong Miao Lulu Han Guohui Dang Yuwei Song Dongmin Yang Zhenling Deng Yue Wang Changtao Jiang Wei Kong Juan Feng Xian Wang | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 2 |
| 3 | Nano-micrometer surface roughness gradients reveal topographical influences on differentiating responses of vascular cells on biodegradable magnesium显示文摘Distinctively directing endothelial cells(ECs)and smooth muscle cells(SMCs),potentially by surface topography cue,is of central importance for enhancing bioefficacy of vascular implants.For the first time,surface gradients with a broad range of nano-micrometer roughness are developed on Mg,a promising next-generation biodegradable metal,to carry out a systematic study on the response of ECs and SMCs.Cell adhesion,spreading,and proliferation are quantified along gradients by high-throughput imaging,illustrating drastic divergence between ECs and SMCs,especially in highly rough regions.The profound role of surface topography overcoming the biochemical cue of released Mg2+is unraveled at different roughness ranges for ECs and SMCs.Further insights into the underlying regulatory mechanism are gained at subcellular and gene levels.Our work enables highefficient exploration of optimized surface morphology for modulating favored cell selectivity of promoting ECs and suppressing SMCs,providing a potential strategy to achieve rapid endothelialization for Mg. | Ke Zhou Yutong Li Lei Zhang Liang Jin Feng Yuan Jinyun Tan Guangyin Yuan Jia Pei | 2021 | Bioactive Materials2021，6，1： | 2 |
| 4 | High-power,electronically controlled source of user-defined vortex and vector light beams based on a few-mode fiber amplifier显示文摘Optical angular momentum(OAM)-based structured light beams provide an additional degree of freedom for practical applications ranging from optical communication to laser-based material processing. Many techniques exist for generating such beams within laser sources and these primarily rely upon the use of specially designed optical components that limit laser power scaling and ready tunability of the topological charge and polarization of the output OAM beams. Here we show that some of these limitations can be overcome by employing a computer controlled reflective phase-only spatial light modulator to adaptively tailor the input(and subsequent output) beam wavefront and polarization in a few-mode fiber amplifier. In this way modal-coupling-induced beam distortion within the fiber amplifier can be mitigated and we are able to generate at will any desired supported spatial mode guided in the fiber, including conventional linearly polarized(LP) modes, scalar OAM modes, and cylindrical vector modes, at average powers >10 W and with a peak power of >11 kW. Our results pave the way to the realization of practical high-power structured laser sources with tunable chirality and polarization. | DI LIN JOEL CARPENTER YUTONG FENG YONGMIN JUNG SHAIF-UL ALAM DAVID J.RICHARDSON | 2021 | Photonics Research2021，9，5： | 2 |
| 5 | Study of hot electrons generated from intense laser-plasma interaction employing Image Plate显示文摘Image Plate (IP) is convenient to be used and very suitable for radiation detection because of its advantages such as wide dynamic range, high detective quantum efficiency, ultrahigh sensitivity and superior linearity. The function mechanism and characteristics of IP are introduced in this paper. IP was employed in the study of hot electrons generated from intense laser-plasma interaction. The angular distri- bution and energy spectrum of hot electrons were measured with IP in the experi- ments. The results demonstrate that IP is an effective radiation detector for the study of laser-plasma interaction. | LIANG WenXi LI YuTong XU MiaoHua YUAN XiaoHui ZHENG ZhiYuan ZHANG Yi LIU Feng WANG ZhaoHua LI HanMing JIN Zhan WEI ZhiYi ZHAO Wei LI YingJun ZHANG Jie | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，10： | 2 |
| 6 | Optimization of Grain Boundary Character Distribution in Fe-18Cr-18Mn-0.63N High-Nitrogen Austenitic Stainless Steel显示文摘Grain boundary engineering(GBE)is a practice of improving resistance to grain boundary failure of the material through increasing the proportion of low Σ coincidence site lattice(CSL)grain boundaries(special grain boundaries)in the grain boundary character distribution(GBCD).The GBCD in a cold rolled and annealed Fe-18Cr-18Mn-0.63N high-nitrogen austenitic stainless steel was analyzed by electron back scatter difraction(EBSD).The results show that the optimization process of GBE in the conventional austenitic stainless steel cannot be well applied to this high-nitrogen austenitic stainless steel.The percentage of lowΣCSL grain boundaries could increase from 47.3%for the solid solution treated high-nitrogen austenitic stainless steel specimen to 82.0%for the specimen after 5%cold rolling reduction and then annealing at 1423 K for 10 min.These special boundaries of high proportion efectively interrupt the connectivity of conventional high angle grain boundary network and thus achieve the GBCD optimization for the high-nitrogen austenitic stainless steel. | Feng SHI Xiaowu LI Yutong HU Chuan SU Chunming LIU | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，5： | 2 |
| 7 | A metabolic intervention strategy to break evolutionary adaptability of tumor for reinforced immunotherapy显示文摘The typical hallmark of tumor evolution is metabolic dysregulation.In addition to secreting immunoregulatory metabolites,tumor cells and various immune cells display different metabolic pathways and plasticity.Harnessing the metabolic differences to reduce the tumor and immunosuppressive cells while enhancing the activity of positive immunoregulatory cells is a promising strategy.We develop a nanoplatform(CLCeMOF)based on cerium metal-organic framework(CeMOF)by lactate oxidase(LOX)modification and glutaminase inhibitor(CB839)loading.The cascade catalytic reactions induced by CLCeMOF generate reactive oxygen species“storm”to elicit immune responses.Meanwhile,LOX-mediated metabolite lactate exhaustion relieves the immunosuppressive tumor microenvironment,preparing the ground for intracellular regulation.Most noticeably,the immunometabolic checkpoint blockade therapy,as a result of glutamine antagonism,is exploited for overall cell mobilization.It is found that CLCeMOF inhibited glutamine metabolism-dependent cells(tumor cells,immunosuppressive cells,etc.),increased infiltration of dendritic cells,and especially reprogrammed CD8^(+)T lymphocytes with considerable metabolic flexibility toward a highly activated,long-lived,and memory-like phenotype.Such an idea intervenes both metabolite(lactate)and cellular metabolic pathway,which essentially alters overall cell fates toward the desired situation.Collectively,the metabolic intervention strategy is bound to break the evolutionary adaptability of tumors for reinforced immunotherapy. | Qianhua Feng Yutong Hao Shuaiqi Yang Xiaomin Yuan Jing Chen Yuying Mei Lanlan Liu Junbiao Chang Zhenzhong Zhang Lei Wang | 2023 | Acta Pharmaceutica Sinica B2023，13，2： | 1 |
| 8 | Injectable Self‑Healing Adhesive pH‑Responsive Hydrogels Accelerate Gastric Hemostasis and Wound Healing显示文摘Endoscopic mucosal resection(EMR)and endoscopic submucosal dissection(ESD)are well-established therapeutics for gastrointestinal neoplasias,but complications after EMR/ESD,including bleeding and perforation,result in additional treatment morbidity and even threaten the lives of patients.Thus,designing biomaterials to treat gastric bleeding and wound healing after endoscopic treatment is highly desired and remains a challenge.Herein,a series of injectable pH-responsive selfhealing adhesive hydrogels based on acryloyl-6-aminocaproic acid(AA)and AA-g-N-hydroxysuccinimide(AA-NHS)were developed,and their great potential as endoscopic sprayable bioadhesive materials to efficiently stop hemorrhage and promote the wound healing process was further demonstrated in a swine gastric hemorrhage/wound model.The hydrogels showed a suitable gelation time,an autonomous and efficient self-healing capacity,hemostatic properties,and good biocompatibility.With the introduction of AA-NHS as a micro-cross-linker,the hydrogels exhibited enhanced adhesive strength.A swine gastric hemorrhage in vivo model demonstrated that the hydrogels showed good hemostatic performance by stopping acute arterial bleeding and preventing delayed bleeding.A gastric wound model indicated that the hydrogels showed excellent treatment effects with significantly enhanced wound healing with type I collagen deposition,α-SMA expression,and blood vessel formation.These injectable self-healing adhesive hydrogels exhibited great potential to treat gastric wounds after endoscopic treatment. | Jiahui He Zixi Zhang Yutong Yang Fenggang Ren Jipeng Li Shaojun Zhu Feng Ma Rongqian Wu Yi Lv Gang He Baolin Guo Dake Chu | 2021 | Nano-Micro Letters2021，13，5： | 1 |
| 9 | Proton radiography of magnetic fields generated with an open-ended coil driven by high power laser pulses显示文摘Recently generation of strong magnetic(B)fields has been demonstrated in capacitor coils heated by high power laser pulses[S.Fujioka et al.,Sci.Rep.3,1170(2013)].This paper will present a direct measurement of B field generated with an open-ended coil target driven by a nanosecond laser pulse using ultrafast proton radiography.The radiographs are analyzed with particle-tracing simulations.The B field at the coil center is inferred to be ~50 T at an irradiance of ~5×10^(14) W·cm^(-2).The B field generation is attributed to the background cold electron flow pointing to the laser focal spot,where a target potential is induced due to the escape of energetic electrons. | Guoqian Liao Yutong Li Baojun Zhu Yanfei Li Fang Li Mengchao Li Xuan Wang Zhe Zhang Shukai He Weiwu Wang Feng Lu Faqiang Zhang Lei Yang Kainan Zhou Na Xie Wei Hong Yuqiu Gu Zongqing Zhao Baohan Zhang Jie Zhang | 2016 | Matter and Radiation at Extremes2016，1，4： | 1 |
| 10 | The influence of target material and thickness on proton energy and angular distribution显示文摘The paper has studied the influence of target material and thickness on energy and angular distributions of the protons generated by using an 800 nm,60 fs,0.24 J laser pulse to irradiate solid target foils.The results show that the initial density and thickness of the targets will affect the formation of the acceleration sheath fields in the target normal direction.For the same target thickness,using lower density target materials can obtain a higher proton maximum energy.However,lower density targets tend to be deformed due to the shock waves launched by the laser pulses,making the proton spatial distribution more divergent. | SU LuNing LIU BiCheng LIN XiaoXuan LIU Feng DU Fei LIU XiaoLong ZHENG Yi GE XuLei LI YuTong SHENG ZhengMing CHEN LiMing WANG WeiMin MA JingLong LU Xin WEI ZhiYi CHEN JiaEr ZHANG Jie | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，2： | 1 |
| 11 | Timing and Single-pulse Study of Pulsar J1909+0122 Discovered by CRAFTS显示文摘We report the discovery of PSR J1909+0122 by the Five-hundred-meter Aperture Spherical Radio Telescope(FAST)as part of the Commensal Radio Astronomy FAST Survey.PSR J1909+0122 has a spin period of 1.257 s and a dispersion measure of 186.2 pc cm^(-3).The averaged pulse profile shows two distinct components.We performed a single-pulse study based on a one-hour observation at 1.25 GHz on 2021 August 23.We used a threshold of 5σ_(ep) to measure the nulling fraction(NF)as 63%±1.5%.The longitude-resolved fluctuation spectra and fast Fourier transform spectra of the binary sequences revealed the quasi-periodicity of nulling with a period of 30 rotation periods.We examined the reliability of the periodicity by comparing it to random noise injection.The NF,E,and modulation periodicity P_(M) of PSR J1909+0122 were compared with other periodic nulling pulsars,showing that the source of J1909+0122 has the second largest NF in the population.Long-term timing observations over six months were used to derive the phase-connected ephemeris of this pulsar.The measured P and P values disfavor dipolar geometry for polar gap models,and the prediction for a space-charge-limited flow model in the case of inverse Compton scattering is only just above the death line.In this work,PSR J1909+0122 has revealed possible correlations between nulling behavior and pulsar properties,which will help to shed light on the pulsar emission mechanism and its temporal evolution in future observations. | Yutong Chen Pei Wang Di Li Erbil Gügercinoğlu Rushuang Zhao Lingqi Meng Jianping Yuan Jiarui Niu Weiwei Zhu Yi Feng Chenchen Miao Chenhui Niu Qingdong Wu Na Wang Shen Wang Xiaoyao Xie Mengyao Xue Jumei Yao Mao Yuan Shanping You Xuhong Yu Youling Yue Jie Zhang Junshuo Zhang Lei Zhang Yabiao Wang Zhenye Gan Yuxi Li Zhongyi Sun Chengjie Wang | 2023 | Research in Astronomy and Astrophysics2023，23，8： | 0 |
| 12 | Molecular mechanism of lycopene cyclases regulating carotenoids ratio in different branches during tea leaf and flower development显示文摘Carotenoids are essential components in tea quality, contributing to leaf color and aroma. However, little information about carotenoids in different tea cultivars and their biosynthesis regulation mechanism during leaf development is known. Here we analyzed carotenoids by HPLC in the buds and leaves of 113 tea cultivars harvested on the same day. By profile clustering, carotenoids were divided into five groups. Same group cultivars displayed divergence in the total content of carotenoids but a similar molar ratio. To figure out the molecular mechanisms of this phenomenon, we further characterized all functional lycopene cyclases, which are the branch point of the carotenoid biosynthesis pathway. Two β-lycopene cyclases(CsLCYB1 and CsLCYB2) and one ε-lycopene cyclase(CsLCYE1) were cloned. Subcellular localization analysis showed that all cloned CsLCYs were localized in plastids. Enzyme activity assays in E. coli indicated both CsLCYBs catalyzed lycopene into β-carotene, and CsLCYE1 produced δ-carotene and ε-carotene. We found CsLCYB1 and CsLCYE1 predominantly expressed in leaf, while CsLCYB2was mainly expressed during flowering stages. Suppression by antisense oligonucleotides reduced CsLCYB1 and CsLCYE1 transcripts and led to reduction of both β,β-branch and β,ε-branch carotenoids in leaf. The expression levels of CsLCYB1 showed a significant positive correlation withβ,β-branch carotenoids in leaf. Our study provides carotenoid profiles of different tea cultivars, which can assist tea producers in selecting cultivars of interest. Meanwhile, we proposed the molecular mechanism of carotenoids reflecting the tenderness of tea plant leaf from a metabolic flux perspective, and suggested lycopene cyclase that could be applied to the breeding of tea varieties with different branch carotenoids. | Anqi Peng Xiaoyan Tang Yingying Feng Yun Huang Jilai Cui Kai Tian Mengqian Lu Yifan Zhao Yuting Pan Sanjin Wang Yutong Hu Wei Zhao Chuankui Song Qiang Wang | 2023 | Horticultural Plant Journal2023，9，6： | 0 |
| 13 | A new method of fast measuring surface tension of melt cast iron and its application in graphite shape identification显示文摘Surface tension is one of important physical features of melt alloy. Many properties of melt alloy, such as graphite shape of cast iron and modified microstructure of aluminum alloy, can be evaluated by means of surface tension. In order to evaluate and control the melt quality in-situ melting operation, the authors advanced a new method and developed an automatic device for fast measuring surface tension of melt alloy and applied it to the practice of rapid identifying graphite shape of cast iron. In this paper, the principle of fast measuring surface tension, the construction of the automatic measurement device and the examples of evaluating graphite shape of cast iron based on the new method and device are discussed. | Dayong LI Dequan SHI Feng LI Yutong ZHANG Jingwei DONG | 2005 | China Foundry2005，2，1： | 0 |
| 14 | Armoring Black Phosphorus Anode with Stable Metal–Organic‑Framework Layer for Hybrid K‑Ion Capacitors显示文摘Potassium-ion capacitors(KICs)are promising for sustainable and eco-friendly energy storage technologies,yet their slow reaction kinetics and poor cyclability induced by large K-ion size are a major obstacle toward practical applications.Herein,by employing black phosphorus nanosheets(BPNSs)as a typical high-capacity anode material,we report that BPNS anodes armored with an ultrathin oriented-grown metal–organic-framework(MOF)interphase layer(BPNS@MOF)exhibit regulated potassium storage behavior for highperformance KICs.The MOF interphase layers as protective layer with ordered pores and high chemical/mechanical stability facilitate K ion diffusion and accommodate the volume change of electrode,beneficial for improved reaction kinetics and enhanced cyclability,as evidenced by substantial characterizations,kinetics analysis and DFT calculations.Consequently,the BPNS@MOF electrode as KIC anodes exhibits outstanding cycle performance outperforming most of the reported state-of-art KICs so far. | Mengzhu Xu Yutong Feng Bingjie Chen Ruijin Meng Mengting Xia Feng Gu Donglei Yang Chi Zhang Jinhu Yang | 2021 | Nano-Micro Letters2021，13，3： | 0 |

| 16 | GDF15 negatively regulates chemosensitivity via TGFBR2-AKT pathway-dependent metabolism in esophageal squamous cell carcinoma显示文摘Treating patients with esophageal squamous cell carcinoma(ESCC)is challenging due to the high chemoresistance.Growth differentiation factor 15(GDF15)is crucial in the development of various types of tumors and negatively related to the prognosis of ESCC patients according to our previous research.In this study,the link between GDF15 and chemotherapy resistance in ESCC was further explored.The relationship between GDF15 and the chemotherapy response was investigated through in vitro and in vivo studies.ESCC patients with high levels of GDF15 expression showed an inferior chemotherapeutic response.GDF15 improved the tolerance of ESCC cell lines to low-dose cisplatin by regulating AKT phosphorylation via TGFBR2.Through an in vivo study,we further validated that the anti-GDF15 antibody improved the tumor inhibition effect of cisplatin.Metabolomics showed that GDF15 could alter cellular metabolism and enhance the expression of UGT1A.AKT and TGFBR2 inhibition resulted in the reversal of the GDF15-induced expression of UGT1A,indicating that TGFBR2-AKT pathway-dependent metabolic pathways were involved in the resistance of ESCC cells to cisplatin.The present investigation suggests that a high level of GDF15 expression leads to ESCC chemoresistance and that GDF15 can be targeted during chemotherapy,resulting in beneficial therapeutic outcomes. | Yingxi Du Yarui Ma Qing Zhu Yong Fu Yutong Li Ying Zhang Mo Li Feiyue Feng Peng Yuan Xiaobing Wang | 2023 | Frontiers of Medicine2023，17，1： | 0 |
