2sLe^(x) expression in invasive micropapillary breast carcinoma is associated with poor prognosis and can be combined with MUC1/EMA as a supplementary diagnostic indicator显示文摘Objective: Mucin 1(MUC1/EMA) and sialyl Lewis X(sLe^(x)) indicate polarity reversal in invasive micropapillary carcinoma(IMPC). The purpose of this study was to evaluate the expression of MUC1/EMA and sLe^(x) and to assess their diagnostic and prognostic value in patients with IMPC.Methods: The expression of sLe^(x) and MUC1/EMA in 100 patients with IMPC and a control group of 89 patients with invasive ductal carcinoma not otherwise specified(IDC-NOS) were analyzed with IHC. Fresh tumor tissues were collected from patients with IMPC or IDC-NOS for primary culture and immunofluorescence analysis.Results: The rate of nodal metastasis was higher in patients with IMPC than those with IDC-NOS, and IMPC cells tended to express more sLe^(x) and MUC1/EMA in the cytomembranes(the stroma-facing surfaces of the micropapillary clusters) than IDC-NOS cells. In IMPC, high cytomembrane expression of sLe^(x), but not MUC1/EMA, indicated poor prognosis. In addition, among the 100 patients with IMPC, 10 patients had sLe^(x)+/EMA-expression patterns, and 8 patients had sLe^(x)-/EMA+ expression patterns. The primary IMPC cells were suspended, non-adherent tumor cell clusters, whereas the primary IDC cells were adherent tumor cells. Immunofluorescence analysis showed that MUC1/EMA and sLe^(x) were co-expressed on the cytomembranes in IMPC cell clusters and in the cytoplasm in IDC-NOS cells.Conclusions: sLe^(x) can be used as a prognostic indicator and can be combined with MUC1/EMA as a complementary diagnostic indicator to avoid missed IMPC diagnosis.Yawen Song Hui Sun Kailiang Wu Jianke Lyu Jingyue Zhang Feng Gu Yongjie Ma Beibei Shen Chijuan Wang Xiaojiao Chen Jing Xu Weidong Li Fangfang Liu Li Fu 2021Cancer Biology & Medicine2021,18,2:7
3Enhanced CO catalytic oxidation by Sr reconstruction on the surface of LaxSr1-xCoO3-δ显示文摘Surface electronic structure of solid materials plays a critical role in heterogeneous catalysis. However,surface chemical composition of the perovskite oxides is usually dominated by segregated A-site cations and the amount of oxygen vacancies is relatively low, which seriously restricts their catalytic oxidation property. Here, we prepare perovskite La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7) with different Sr doping amount and experiment results show that perovskite LSCO with higher content of surface Sr possesses more oxygen vacancies and better catalytic activity. On this basis, we develop a new experimental strategy to create more surface oxygen vacancies to promote their CO catalytic activity. In this method, we use high active hydrogen atoms(BH^(4-)) as reductant to realize surface in-situ chemical composite modification of La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7), which causes their surface reconstruction(surface Sr enrichment).The regulation mainly focuses on the atomic layer level without damaging their bulk phase structure.Different from traditional high temperature annealing under reducing atmosphere, this method is high-efficiency, green and controllable. Furthermore, we study the surface reconstruction process and demonstrated that it is atomic layer engineering on the surface of La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7) by X-ray photoelectron spectroscopy(XPS) and X-ray absorption fine structure(XAFS). Our experiment results also show that these samples treated by this method exhibit superior activity for CO oxidation compared with original samples.Xiyang Wang Keke Huang Jingyu Qian Yingge Cong Chengda Ge Shouhua Feng 2017Science Bulletin2017,62,9:5
4A comparison between acute large vessel occlusion in the posterior circulation and anterior circulation after endovascular treatment:the ANGEL-ACT registry experience显示文摘Background and purpose Endovascular treatment(EVT)has shown an overwhelming benefit for acute anterior circulation artery occlusion(ACO).Whether it can achieve the same outcomes in posterior circulation artery occlusion(PCO)has not been well explained.We aimed to evaluate the characteristics and prognosis of ACO and PCO after EVT in a nationwide registry.Method The present analysis was based on the prospective ANGEL-ACT Registry in China between November 2017 and March 2019.Demographic data,periprocedural times,recanalisation rate,intracranial haemorrhage(ICH)and 90-day functional outcomes were compared between the ACO and PCO groups.Results A total of 1793 patients were analysed including 397(22.1%)consecutive patients with PCO and 1396(77.9%)patients with ACO treated with EVT.A larger proportion of patients with PCO had intracranial atherosclerotic disease and received extra angioplasty during EVT.Successful recanalisation and 90-day favourable functional outcomes did not differ significantly between the two groups.Patients with PCO showed lower 24-hour ICH and symptomatic ICH rates.There was a trend towards higher mortality rate in the PCO group(22.09%vs 14.44%;adjusted OR 1.286(95%CI 0.820 to 2.017),p=0.2731),especially when the onset to puncture time was over 6 hours(30.77%vs 11.13%;adjusted OR 2.673(95%CI 1.280 to 5.583),p=0.0089,interactive p=0.0002).Conclusions In this large prospective multicentre registry,there was a significant difference in the characteristics and periprocedural features between patients with PCO and ACO.However,successful recanalisation and 90-day favourable functional outcomes in PCO were equivalent to those in ACO.Xuan Sun Jingyu Zhang Xu Tong Baixue Jia Dapeng Mo Ning Ma Feng Gao Lian Liu Xiaochuan Huo Ligang Song Yiming Deng Zhongrong Miao 2022Stroke & Vascular Neurology2022,7,4:4
5Exosomes Released from Rabies Virus-Infected Cells May be Involved in the Infection Process显示文摘Exosomes are cell-derived vesicles that are secreted by many eukaryotic cells. It has recently attracted attention as vehicles of intercellular communication. Virus-infected cells release exosomes, which contain viral proteins, RNA, and pathogenic molecules. However, the role of exosomes in virus infection process remains unclear and needs to be further investigated.In this study, we aimed to evaluate the effects of exosomes on rabies virus infection. OptiPrep^(TM) density gradient centrifugation was used to isolate exosomes from rabies virus-infected cell culture supernatants. A rabies virus G protein enzyme-linked immunosorbent assay and acetylcholinesterase activity assays were performed to verify the centrifugation fractions. Exosomes were then characterized using transmission electron microscopy and Western blotting. Our results showed that rabies virus infection increased the release of exosomes. Treatment with GW4869 and si-Rab27 a, two exosomal secretion inhibitors, inhibited exosome release. Furthermore, the inhibitors reduced the levels of extracellular and intracellular viral RNA. These data indicated that exosomes may participate in the viral infection process. Moreover, our results establish a basis for future research into the roles of exosomes in rabies virus infection and as potential targets for developing new antiviral strategies.Jingyu Wang Fan Wu Chuntian Liu Wenwen Dai Yawei Teng Weiheng Su Wei Kong Feng Gao Linjun Cai Ali Hou Chunlai Jiang 2019Virologica Sinica2019,34,1:3
6Confining TiO_2 Nanotubes in PECVD-Enabled Graphene Capsules Toward Ultrafast K-Ion Storage: In Situ TEM/XRD Study and DFT Analysis显示文摘Titanium dioxide(TiO2) has gained burgeoning attention for potassium-ion storage because of its large theoretical capacity,wide availability,and environmental benignity.Nevertheless,the inherently poor conductivity gives rise to its sluggish reaction kinetics and inferior rate capability.Here,we report the direct graphene growth over TiO2 nanotubes by virtue of chemical vapor deposition.Such conformal graphene coatings effectively enhance the conductive environment and well accommodate the volume change of TiO2 upon potassiation/depotassiation.When paired with an activated carbon cathode,the graphene-armored TiO2 nanotubes allow the potassium-ion hybrid capacitor full cells to harvest an energy/power density of 81.2 Wh kg-1/3746.6 W kg-1.We further employ in situ transmis sion electron microscopy and ope rando X-ray diffraction to probe the potassium-ion storage behavior.This work offers a viable and versatile solution to the anode design and in situ probing of potassium storage technologies that is readily promising for practical applications.Jingsheng Cai Ran Cai Zhongti Sun Xiangguo Wang Nan Wei Feng Xu Yuanlong Shao Peng Gao Shixue Dou Jingyu Sun 2020Nano-Micro Letters2020,12,9:2
7Characterization of DNA damage response deficiency in pancreatic cancer patients from China显示文摘To the editor,Pancreatic ductal adenocarcinoma(PDAC)has the worst prognosis among all common malignant solid tumors,with a 5-year overall survival(OS)rate of less than 10%[1].Few effective targets for anticancer ther-apy have been confirmed in pancreatic cancer.Recently,it was substantiated that pancreatic cancer patients carry-ing deleterious mutations of the DNA damage response(DDR)genes are more likely to benefit from platinum-based chemotherapy[2]and poly(adenosine diphosphate-ribose)polymerase(PARP)inhibitor[3].Xiaofei Zhang Tiebo Mao Bei Zhang Haiyan Xu Jiujie Cui Feng Jiao Dongqin Chen Yu Wang Jiong Hu Qing Xia Shumin Li Ming Yue Jingyu Ma Jiayu Yao Yongchao Wang Xiao Zhang Shiqing Chen Yuezong Bai Yuexiang Wang Xuebin Zhang Qiang Liu Yongwei Sun Deliang Fu Yingbin Liu Lei Xiong Liwei Wang 2022Cancer Communications2022,42,1:2
8Broad temperature adaptability of vanadium redox flow battery-part4:Unraveling wide temperature promotion mechanism of bismuth for V^(2+)/V^(3+) couple显示文摘Vanadium flow battery(VFB)is a fast going and promising system for large-scale stationary energy storage.However,drawbacks such as low power density and narrow temperature window caused by poor catalytic activity of graphite felt(GF)electrodes limit its worldwide application.In this paper,bismuth,as a low-cost,no-toxic and high-activity electrocatalyst,is used to modify the thermal activated GF(TGF)via a facile hydrothermal method.Bismuth can effectively inhibit the side reaction of hydrogen evolution in wide temperature range,while promoting the V^(2+)/V^(3+)redox reaction.As a result,the VFB assembled with Bi/TGF as negative electrode demonstrates outstanding rate performance under the current density up to 400 mA cm^(-2),as well as a long-term stability over 600 charging/discharging cycles at a high current density of 150 mA cm^(-2).Moreover,it also shows excellent temperature adaptability from-10°C to50°C and high durability for life test at the temperature of 50°C.Yuchen Liu Feng Liang Yang Zhao Lihong Yu Le Liu Jingyu Xi 2018Journal of Energy Chemistry2018,27,5:2

16Understanding the dynamical-microphysical-electrical processes associated with severe thunderstorms over the Beijing metropolitan region显示文摘The Dynamical-microphysical-electrical Processes in Severe Thunderstorms and Lightning Hazards(STORM973)project conducted coordinated comprehensive field observations of thunderstorms in the Beijing metropolitan region(BMR)during the warm season from 2014 to 2018.The aim of the project was to understand how dynamical,microphysical and electrical processes interact in severe thunderstorms in the BMR,and how to assimilate lightning data in numerical weather prediction models to improve severe thunderstorm forecasts.The platforms used in the field campaign included the Beijing Lightning Network(BLNET,consisting of 16 stations),2 X-band dual linear polarimetric Doppler radars,and 4 laser raindrop spectrometers.The collaboration also made use of the China Meteorological Administration’s mesoscale meteorological observation network in the Beijing-Tianjin-Hebei region.Although diverse thunderstorm types were documented,it was found that squall lines and multicell storms were the two major categories of severe thunderstorms with frequent lightning activity and extreme rainfall or unexpected local short-duration heavy rainfall resulting in inundations in the central urban area,influenced by the terrain and environmental conditions.The flash density maximums were found in eastern Changping District,central and eastern Shunyi District,and the central urban area of Beijing,suggesting that the urban heat island effect has a crucial role in the intensification of thunderstorms over Beijing.In addition,the flash rate associated with super thunderstorms can reach hundreds of flashes per minute in the central city regions.The super(5%of the total),strong(35%),and weak(60%)thunderstorms contributed about 37%,56%,and 7%to the total flashes in the BMR,respectively.Owing to the close connection between lightning activity and the thermodynamic and microphysical characteristics of the thunderstorms,the lightning flash rate can be used as an indicator of severe weather events,such as hail and short-duration heavy rainfall.Lightning data can also be assimilated into numerical weather prediction models to help improve the forecasting of severe convection and precipitation at the cloud-resolved scale,through adjusting or correcting the thermodynamic and microphysical parameters of the model.Xiushu QIE Shanfeng YUAN Zhixiong CHEN Dongfeng WANG Dongxia LIU Mengyu SUN Zhuling SUN Abhay SRIVASTAVA Hongbo ZHANG Jingyu LU Hui XIAO Yongheng BI Liang FENG Ye TIAN Yan XU Rubin JIANG Mingyuan LIU Xian XIAO Shu DUAN Debin SU Chengyun SUN Wenjing XU Yijun ZHANG Gaopeng LU Da-Lin ZHANG Yan YIN Ye YU 2021Science China Earth Sciences2021,64,1:1
17Infection of post-harvest peaches by Monilinia fructicola accelerates sucrose decomposition and stimulates the Embden–Meyerhof–Parnas pathway显示文摘To study the changes in sugar metabolism caused by fungal infection in post-harvest peaches,fruit from two cultivars(‘Baifeng’and‘Yulu’)was inoculated with Monilinia fructicola and stored at 10°C.During disease development,soluble sugar content was monitored,as well as the activities and expression of selected enzymes.Disease progression was accompanied by a decrease in sucrose content and increases in reducing sugars and soluble solids,consistent with higher enzyme activities for acid invertase,neutral invertase and sucrose synthase-cleavage,and lower activities for sucrose synthase-synthesis and sucrose phosphate synthase.Activities of phosphofructokinase,hexokinase,and pyruvate kinase,which are related to hexose metabolism,also increased.These changes stimulate the Embden–Meyerhof–Parnas(EMP)pathway.We conclude that the fungal disease in peach fruit accelerates the decomposition of sucrose,thereby providing more glucose as a substrate to the EMP pathway.Jingyu Kou Yingying Wei Xingxing He Jiayu Xu Feng Xu Xingfeng Shao 2018Horticulture Research2018,5,1:1

19P-doped electrode for vanadium flow battery with high-rate capability and all-climate adaptability显示文摘A phosphorous-doped graphite felt(PGF) is fabricated and examined as electrode for vanadium flow battery(VFB). P doping improves the electrolyte wettability of GF and induces more defect sites on its surface, resulting in significantly enhanced activity and reversibility towards VO2^+/VO2^+ and V^2+/V3^+couples. VFB with PGF electrode demonstrates outstanding performance such as high-rate capability under 50–400 mA cm^-2, wide-temperature tolerance at-20 °C–60 °C, and excellent durability over 1000 charge–discharge cycles. These merits enable PGF a promising electrode for the next-generation VFB,which can operate at high-power and all-climate conditions.Lihong Yu Feng Lin Lin Xu Jingyu Xi 2019Journal of Energy Chemistry2019,28,8:1
