2Endovascular treatment with or without intravenous alteplase for acute ischaemic stroke due to basilar artery occlusion显示文摘Background and purpose It remains controversial if endovascular treatment(EVT)can improve the outcome of patients with acute basilar artery occlusion(BAO).This study aims to compare the functional outcomes between EVT with and without intravenous thrombolysis(IVT)first in patients who had acute ischaemic stroke(AIS)due to BAO.Methods Patients who had AIS with BAO who underwent EVT within 24 hours of onset were enrolled in this multicentre cohort study,and the efficacy and safety were compared between IVT+EVT and direct EVT.The primary outcome was 90-day functional independence.All outcomes were assessed with adjusted OR(aOR)from the multivariable logistic regression.In addition,a meta-analysis was performed on all recently published pivotal studies on functional independence after EVT in patients with BAO.Results Of 310 enrolled patients with BAO,241(78%)were treated with direct EVT and 69(22%)with IVT+EVT.Direct EVT was associated with a worse functional outcome(aOR,0.46(95%CI 0.24 to 0.85),p=0.01).IVT+EVT was associated with a lower percentage of patients who needed≥3 passes of stent retriever(10.14%vs 20.75%).The meta-analysis regression revealed a potential positive correlation between bridging with IVT first and functional independence(r=0.14(95%CI 0.05 to 0.24),p<0.01).Conclusions This study showed that compared with direct EVT,EVT with IVT first was associated with better functional outcomes in patients with BAO treated within 24 hours of onset.The meta-analysis demonstrated similar favourable efficacy of IVT first followed by EVT in patients with BAO.Ximing Nie David Wang Yuehua Pu Yufei Wei Qixuan Lu Hongyi Yan Xin Liu Lina Zheng Jingyi Liu Xinxuan Yang Yarong Ding Dacheng Liu Wanying Duan Zhe Zhang Zhonghua Yang Miao Wen Weibin Gu Xinyi Hou Xinyi Leng Yuesong Pan Zhongrong Miao Liping Liu 2022Stroke & Vascular Neurology2022,7,3:10
3Two-dimensional self-healing hydrogen-bond-based supramolecula polymer film显示文摘Self-healing materials have been developed over the past decade with the recovery ability after damage.However,most researches focused on the self-healing process at three-dimension.Herein,we prepare monolayer self-healing hydrogen-bond-based supramolecular polymer film and explore the self-healing process at the two-dimensional limit.The healing process,which can be reversibly repeated for at least three times,is influenced by the temperature,the molecule-substrate interaction and the substrate roughness.In the application,the monolayer self-healing polymer film can be used to modify the SiO2 dielectric for copper phthalocyanine field effect transistor with improved mobility.This work will be valuable for developing two-dimensional functional self-healing materials in the future.Mengnan He Xiaosong Chen Donghua Liu Dacheng Wei 2019Chinese Chemical Letters2019,30,5:5
4Minimizing Purifi cation-Induced Defects in Single-Walled Carbon Nanotubes Gives Films with Improved Conductivity显示文摘A method for the non-destructive purification of single-walled carbon nanotubes(SWNTs)using classical coordination chemistry to remove the metal catalyst has been developed.In preliminary tests,the conductivity of films based on the resulting SWNTs was markedly better than that of films prepared from SWNTs purified by treatment with oxidizing acid solutions.The transparent and conducting SWNT films have potential applications in optoelectronic devices.Yu Wang Liping Huang Yunqi Liu Dacheng Wei Hongliang Zhang Hisashi Kajiura Yongming Li 2009Nano Research2009,2,11:3
5A 3D printable self-healing composite conductive polymer for sensitive temperature detection显示文摘Recent development of self-healing material has attracted tremendous attention,owing to its biomimetic ability to restore structure and functionality when encountering damages.Here,we develop a threedimensional(3D)printable self-healing composite conductive polymer by mixing hydrogen-bond-based supramolecular polymer with low-cost carbon black.It has a room-temperature self-healing capability in both conductivity and mechanical property,while its shear-thinning behavior enables fabrication of a self-healable circuit by 3D printing technology.As an application,the circuit shows an excellent temperature-dependent behavior of the resistance,indicating its great potential fo r practical application in the artificial intelligence field.Mengnan He Yan Zhao Yunqi Liu Dacheng Wei 2020Chinese Chemical Letters2020,31,3:3
6China 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 2021Stroke & Vascular Neurology2021,6,2:3

9Suppression of ETI by PTI priming to balance plant growth and defense through an MPK3/MPK6-WRKYs-PP2Cs module显示文摘Pattern-triggered immunity(PTI)and effector-triggered immunity(ETI)are required for host defense against pathogens.Although PTI and ETI are intimately connected,the underlying molecular mechanisms remain elusive.In this study,we demonstrate that flg22 priming attenuates Pseudomonas syringae pv.tomato DC3000(Pst)AvrRpt2-induced hypersensitive cell death,resistance,and biomass reduction in Arabidopsis.Mitogen-activated protein kinases(MAPKs)are key signaling regulators of PTI and ETI.The absence of MPK3 and MPK6 significantly reduces pre-PTI-mediated ETI suppression(PES).We found that MPK3/MPK6 interact with and phosphorylate the downstream transcription factor WRKY18,which regulates the expression of AP2C1 and PP2C5,two genes encoding protein phosphatases.Furthermore,we observed that the PTI-suppressed ETI-triggered cell death,MAPK activation,and growth retardation are significantly attenuated in wrky18/40/60 and ap2c1 pp2c5 mutants.Taken together,our results suggest that the MPK3/MPK6-WRKYs-PP2Cs module underlies PES and is essential for the maintenance of plant fitness during ETI.Dacheng Wang Lirong Wei Ting Liu Jinbiao Ma Keyi Huang Huimin Guo Yufen Huang Lei Zhang Jing Zhao Kenichi Tsuda Yiming Wang 2023Molecular Plant2023,16,5:1
10Graphene plasmonic nanoresonators/graphene heterostructures for efficient room-temperature infrared photodetection显示文摘High-performance infrared(IR)photodetectors made by low dimensional materials promise a wide range of applications in communication,security and biomedicine.Moreover,light-harvesting effects based on novel plasmonic materials and their combinations with two-dimensional(2 D)materials have raised tremendous interest in recent years,as they may potentially help the device complement or surpass currently commercialized IR photodetectors.Graphene is a particularly attractive plasmonic material because graphene plasmons are electrically tunable with a high degree of electromagnetic confinement in the mid-infrared(mid-IR)to terahertz regime and the field concentration can be further enhanced by forming nanostructures.Here,we report an efficient mid-IR room-temperature photodetector enhanced by plasmonic effect in graphene nanoresonators(GNRs)/graphene heterostructure.The plasmon polaritons in GNRs are size-dependent with strong field localization.Considering that the size and density of GNRs are controllable by chemical vapor deposition method,our work opens a cost-effective and scalable pathway to fabricate efficient IR optoelectronic devices with wavelength tunability.Tian Sun Weiliang Ma Donghua Liu Xiaozhi Bao Babar Shabbir Jian Yuan Shaojuan Li Dacheng Wei Qiaoliang Bao 2020Journal of Semiconductors2020,41,7:1
