1Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders: executive summary and 2019 update of clinical management of ischaemic cerebrovascular diseases显示文摘Aim Stroke is the leading cause of disability and death in China.Ischaemic stroke accounts for about 60%-80%of all strokes.It is of considerable significance to carry out multidimensional management of ischaemic cerebrovascular diseases.This evidence-based guideline aims to provide the latest detailed and comprehensive recommendations on the diagnosis,treatment and secondary prevention of ischaemic cerebrovascular diseases.Methods We had performed comprehensive searches of MEDLINE(via PubMed)(before 30 June 2019),and integrated the relevant information into charts and distributed to the writing group.Writing group members discussed and determined the recommendations through teleconference.We used the level of evidence grading algorithm of Chinese Stroke Association to grade each recommendation.The draft was reviewed by the Guideline Writing Committee of Chinese Stroke Association Stroke and finalised.This guideline is fully updated every 3 years.results This evidence-based guideline is based on the treatment,care and prevention of ischaemic cerebrovascular diseases,which emphasises on pathogenesis evaluation,intravenous thrombolysis,endovascular therapy,antiplatelet therapy,prevention and treatment of complications,and risk factor management.Conclusions This updated guideline presents a framework for the management of ischaemic cerebrovascular diseases.Timely first-aid measures,professional care in the acute stage,and proactive secondary prevention will be helpful to patients.Liping Liu Weiqi Chen Hongyu Zhou Wanying Duan Shujuan Li Xiaochuan Huo Weihai Xu Li'an Huang Huaguang Zheng Jingyi Liu Hui Liu Yufei Wei Jie Xu Yongjun Wang 2020Stroke & Vascular Neurology2020,5,2:42
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
3Branched tetraether lipids in Chinese soils:Evaluating the fidelity of MBT/CBT proxies as paleoenvironmental proxies显示文摘The ubiquitous occurrence of branched glycerol dialkyl glycerol tetraethers(br GDGTs) in soils has allowed development of new proxies for reconstruction of past climate and environment. The methylation and cyclization degrees of br GDGTs, expressed as MBT and CBT, respectively, are reported to be mainly controlled by mean annual air temperature(MAAT) and soil p H. However, the br GDGT-derived temperatures and soil p H scatter widely when data from different environmental conditions are considered. In this study, we collected over 300 soil samples from China, which are representative of humid(Xishuangbanna, Guangzhou, and Shanghai), semi-arid(Dongying) and semi-arid/arid(Lanzhou, Tibetan Plateau) regions. Collectively we have the most extensive dataset that broadly characterizes the distribution of br GDGTs according to climate zones in China. The overall data demonstrate that the MBT/CBT derived temperatures better match the measured MAATs in humid and non-alkaline regions than those from regions of low MAP(<400 mm/yr) and above neutral soil p H(>7.0–7.5). Similarly, CBT describes soil p H much better in humid and non-alkaline soils than in semi-arid/arid and alkaline soils; the semi-arid/arid and alkaline soils tend to show a positive correlation between soil p H and CBT, which contradicts that in the humid and non-alkaline soils. While soil p H, MAAT and mean annual precipitation(MAP) are dominating factors controlling the br GDGT distribution across all climate zones, conductivity, total organic carbon and total nitrogen, as well as soil water content can also play an important role locally. Removing br GDGT-II resulted in a revised CBT index that provides more accurate estimation of p H, especially in semi-arid/arid and alkaline soils. The overall Chinese dataset demonstrates that continental air temperature derived from br GDGT-proxies can vastly deviate from real measurements and should be used with extreme caution in paleo-climate or-environment studies.ZHENG FengFeng ZHANG ChuanLun CHEN YuFei LI FuYan MA CenLing PU Yang ZHU YuanQing WANG YongLi LIU WeiGuo 2016Science China Earth Sciences2016,59,7:10

5Ultrasensitive and stable X-ray detection using zero-dimensional lead-free perovskites显示文摘Sensitive and reliable X-ray detectors are essential for medical radiography,industrial inspection and security screening.Lowering the radiation dose allows reduced health risks and increased frequency and fidelity of diagnostic technologies for earlier detection of disease and its recurrence.Three-dimensional(3 D)organic-inorganic hybrid lead halide perovskites are promising for direct X-ray detection-they show improved sensitivity compared to conventional X-ray detectors.However,their high and unstable dark current,caused by ion migration and high dark carrier concentration in the 3 D hybrid perovskites,limits their performance and long-term operation stability.Here we report ultrasensitive,stable X-ray detectors made using zero-dimensional(0 D)methylammonium bismuth iodide perovskite(MA3Bi2I9)single crystals.The 0 D crystal structure leads to a high activation energy(Ea)for ion migration(0.46 e V)and is also accompanied by a low dark carrier concentration(~10^6 cm^-3).The X-ray detectors exhibit sensitivity of 10,620μC Gy-1 air cm-2,a limit of detection(Lo D)of 0.62 nG yairs-1,and stable operation even under high applied biases;no deterioration in detection performance was observed following sensing of an integrated X-ray irradiation dose of^23,800 m Gyair,equivalent to>200,000 times the dose required for a single commercial X-ray chest radiograph.Regulating the ion migration channels and decreasing the dark carrier concentration in perovskites provide routes for stable and ultrasensitive X-ray detectors.Xiaojia Zheng Wei Zhao Peng Wang Hairen Tan Makhsud I.Saidaminov Shujie Tie Ligao Chen Yufei Peng Jidong Long Wen-HuZhang 2020Journal of Energy Chemistry2020,29,10:7

7Tuning 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 2020Journal of Energy Chemistry2020,29,7:5
8The Effect of 2,5-hexanedione on Myelin Protein Zero Expression,and Its Mitigation Using Ginkgo Biloba Extract显示文摘Objective To investigate the role of myelin protein zero (P 0) in 2,5-hexanedione (2,5-HD)-induced peripheral nerve injury,and the protective effect of Ginkgo biloba extract (Egb761) on 2,5-HD-induced toxic peripheral neuropathy.Methods After 4 weeks of treatment with 2,5-HD at different doses (50,100,200,400 mg/kg) in rats,changes in the levels of P 0 in rat sciatic nerves was investigated,and the effect of Egb761 on 2,5-HD-induced toxic peripheral neuropathy was studied.Results The blood-nerve barrier (BNB) permeability of the sciatic nerve increased,and the expression of P 0 mRNA and P 0 protein decreased in a dose-dependent manner after treatment with 2,5-HD for 4 weeks.Pretreatment with Egb761 protected against BNB interruption,and inhibited P 0 mRNA and protein reduction during 2,5-HD treatment.Pretreatment with Egb761 significantly reduced loss of body weight (P<0.01) and mitigated gait abnormalities (2.85±0.22) induced by 400 mg/kg 2,5-HD (P<0.01).It also reduced the signs of neurotoxicity induced by 2,5-HD.Conclusion 2,5-HD inhibited the expression of P 0 in a dose-dependent manner,and this may be an important mechanism by which toxic peripheral neuropathy is induced by 2,5-HD.Egb761 has a protective effect against 2,5-HD-induced peripheral neurotoxicity in rats.ZHAO Lei LIU QingJun CHEN Hong DUAN HuaWei BIN Ping LIU Qing NIU Yong DAI YuFei ZHENG YuXin 2011Biomedical and Environmental Sciences2011,24,4:3

11RNA-Seq Study Reveals AP2-Domain-Containing Signalling Regulators Involved in Initial Imbibition of Seed Germination in Rice显示文摘A number of internal signals are required for seed germination.However,the precise signalling responses in the initial imbibition of seed germination are not yet fully understood in rice.In this study,the RNA sequencing(RNA-Seq)approach was conducted in 8 h imbibed seeds to understand the signalling responses in the initial imbibition of rice seed germination.A total of 563 differentially expressed genes(DEGs)with at least 4-fold change were identified in 8 h imbibed seeds compared to dry seeds.MapMan analysis revealed that the majority of signalling response-related DEGs were hormone-and transcription factor-related genes,in which the largest number of DEGs belong to the AP2-domain-containing regulators,and their expressions were significantly induced in the initial imbibition of seed germination in rice.Moreover,at least five AP2-domain-containing transcription factor OsDREBs were identified in the initial imbibition of rice seed germination,and the expressions of 251 DEGs were putatively regulated by OsDREBs through the dehydration-responsive element(DRE)cis-element assay.It suggested that the OsDREBs might play important roles in the regulation of initial seed imbibition in rice.The identified genes provide a valuable resource to study the signalling regulation of seed germination in the future.HE Yongqi ZHAO Jia FENG Defeng HUANG Zhibo LIANG Jiaming ZHENG Yufei CHENG Jinping YING Jifeng WANG Zhoufei 2020Rice science2020,27,4:2
12Cartilage 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 2021Cell Research2021,31,7:2
13Comparision of China's volatile organic compound pollution management:a computable general equilibrium approach显示文摘The public health and ecological impacts of volatile organic compound(VOCs) pollution have become a serious problem in China,arousing increasing attention to emissions control.In this context,this paper analyses the effectiveness of VOC reduction policies,namely pollution charges and environmental taxes at the national and industrial sector levels.It uses a computable general equilibrium model,which connects macroeconomic variables with VOC emissions inventory,to simulate the effects of policy scenarios(with 2007 as the reference year).This paper shows that VOC emissions are reduced by 2.2% when a pollution charge equal to the average cost of engineering reduction methods-the traditional approach to regulation in China-is applied.In order to achieve a similar reduction,an 8.9% indirect tax would have to be imposed.It concludes that an environmental tax should be the preferred method of VOC regulation due to its smaller footprint on the macroeconomy.Other policies,such as subsidies,should be used as supplements.Yufei Wang Changxin Liu Tong Wu Zhengping Hao Zheng Wang 2016Chinese Journal of Population,Resources and Environment2016,16,4:2

15In-situ constructing visible light CdS/Cd-MOF photocatalyst with enhanced photodegradation of methylene blue显示文摘Based on high specific surface area,high porosity of metal-organic frameworks(MOFs)and excellent vis-ible light response of CdS,the CdS/Cd-MOF nanocomposites were constructed by in-situ sulfurization to form CdS using Cd-MOF as precursor and the CdS loading was controlled by the dose of thioac-etamide.Under the irradiation of simulated sunlight,the degradation rate of methylene blue(MB)by 10mg MOF/CdS-6(mass ratio of MOF to thioacetamide is 6:1)was 91.9%in 100min,which was higher than that of pure Cd-MOF(62.3%)and pure CdS(67.5%).This is attributed to the larger specific surface area of the composite catalysts,which provides more active sites.Meanwhile,the loading of CdS obvi-ously broadens the light response range of Cd-MOF and improves the utilization of visible light.The Mott-Schottky model experiment shows that the formed type-Ⅱheterojunction between Cd-MOF and CdS can effectively inhibit the recombination of photogenerated electrons and holes.Meanwhile,the photocurrent intensity of MOF/CdS-6 is 8 times and 2.5 times of that of pure Cd-MOF and CdS.In addi-tion,MOF/CdS-6 showed good photocatalytic performance after five cycles,showing excellent stability and reusability.Cheng Jing Yufei Zhang Junjie Zheng Shengsong Ge Jing Lin Duo Pan Nithesh Naik Zhanhu Guo 2022Particuology2022,20,10:1

17Hybrid grid generation for viscous flow simulations in complex geometries显示文摘In this paper,we present a hybrid grid generation approach for viscous flow simulations by marching a surface triangulation on viscous walls along certain directions.Focuses are on the computing strategies used to determine the marching directions and distances since these strategies determine the quality of the resulting elements and the reliability of the meshing procedure to a large extent.With respect to marching directions,three strategies featured with different levels of efficiencies and robustness performance are combined to compute the initial normals at front nodes to balance the trade-off between efficiency and robustness.A novel weighted strategy is used in the normal smoothing scheme,which evidently reduces the possibility of early stop of front generation at complex corners.With respect to marching distances,the distance settings at concave and/or convex corners are locally adjusted to smooth the front shape at first;a further adjustment is then conducted for front nodes in the neighbourhood of gaps between opposite viscous boundaries.These efforts,plus other special treatments such as multi-normal generation and fast detection of local/global intersection,as a whole enable the setup of a hybrid mesher that could generate qualitied viscous grids for geometries with industry-level complexities.Hongfei Ye Yang Liu Bo Chen Zhiwei Liu Jianjing Zheng Yufei Pang Jianjun Chen 2020Advances in Aerodynamics2020,2,1:1

19The mechanism and therapy of aortic aneurysms显示文摘Aortic aneurysm is a chronic aortic disease affected by many factors.Although it is generally asymptomatic,it poses a significant threat to human life due to a high risk of rupture.Because of its strong concealment,it is difficult to diagnose the disease in the early stage.At present,there are no effective drugs for the treatment of aneurysms.Surgical intervention and endovascular treatment are the only therapies.Although current studies have discovered that inflammatory responses as well as the production and activation of various proteases promote aortic aneurysm,the specific mechanisms remain unclear.Researchers are further exploring the pathogenesis of aneurysms to find new targets for diagnosis and treatment.To better understand aortic aneurysm,this review elaborates on the discovery history of aortic aneurysm,main classification and clinical manifestations,related molecular mechanisms,clinical cohort studies and animal models,with the ultimate goal of providing insights into the treatment of this devastating disease.The underlying problem with aneurysm disease is weakening of the aortic wall,leading to progressive dilation.If not treated in time,the aortic aneurysm eventually ruptures.An aortic aneurysm is a local enlargement of an artery caused by a weakening of the aortic wall.The disease is usually asymptomatic but leads to high mortality due to the risk of artery rupture.Jianing Gao Huanhuan Cao Gaofei Hu Yufei Wu Yangkai Xu Hongtu Cui Hong S.Lu Lemin Zheng 2023Signal Transduction and Targeted Therapy2023,8,3:1
