1Endovascular 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
2Endovascular therapy for Acute ischemic Stroke Trial (EAST): study protocol for a prospective, multicentre control trial in China显示文摘Background and purpose:5 recent trials have shown the benefit of endovascular treatment for acute ischaemic stroke(AIS)due to large vessel occlusion of the anterior circulation.This study aims to evaluate the safety and efficacy of Solitaire thrombectomy in patients with moderate-to-severe stroke in the Chinese population,which has a high prevalence of intracranial atherosclerosis.Methods and analysis:This multicentre prospective control study will involve 17 stroke centres in China,and plans to recruit 150 patients in the intervention group,and 150 patients in the medical group,in which patients meet enrolment criteria but refuse intervention.Patients with AIS due to large vessel occlusion indicated for treatment with Solitaire stent retriever within 12 hours of symptom onset,and who meet the inclusion and exclusion criteria,will be enrolled in this study.The primary efficacy endpoint is functional independence as defined by a modified Rankin Scale(mRS)score≤2 at 90 days or by functional improvement as defined by mRS,using shift analysis.The procedural efficacy endpoint is arterial recanalisation of the occluded target vessel measured by a modified Thrombolysis in Cerebral Infarction(mTICI)score equal or superior to 2b right following the use of the study device.The primary safety endpoint is symptomatic intracranial haemorrhage(sICH)within 24±3 hours postprocedure.Ethics and dissemination:The protocol was approved by the Ethics Committee at the coordinating centre and by the local Institutional Review Board of each participating centre.Trial registration number:NCT02350283.Zhongrong Miao Xiaochuan Huo Feng Gao Xiaoling Liao Chunjuan Wang Ya Peng Yibin Cao Shengli Chen Meng Zhang Changchun Jiang Xiaoxiang Peng Cunfeng Song Liping Wei Qiyi Zhu Zaiyu Guo Li Liu Hang Lin Hua Yang Wei Wu Hui Liang Anding Xu Kangning Chen Xingquan Zhao Yuesong Pan Hao Li Liping Liu Yilong Wang Yongjun Wang EAST investigators 2016Stroke & Vascular Neurology2016,1,2:8
3Simultaneous regulation of cations and anions in an electrolyte for high-capacity, high-stability aqueous zinc–vanadium batteries显示文摘Safe,inexpensive aqueous zinc-ion batteries(AZIBs)are regarded as promising energy storage devices.However,they still face issues,including dissolution and collapse of the cathode as well as H_(2)evolution and the growth of Zn dendrites on the Zn anode.Herein,we simultaneously regulate the cations and anions in the electrolyte for high-capacity,high-stability aqueous zinc–vanadium(Zn–V)batteries based on a bimetallic cation-doped Na_(0.33)K_(0.1)V_(2)O_(5)·nH_(2)O cathode.We demonstrate that Na^(+) cations suppress cathode dissolution and restrain Zn dendrite growth on the anode via an electrostatic shield effect.We also illustrate that ClO_(4)^(-) anions participate in energy storage at the cathode and are reduced to Cl^(-),generating a protective layer on the Zn anode surface and providing a stable interface to decrease Zn dendrites and H_(2)evolution during long-term cycling.When Na^(+) and ClO_(4)^(-) are introduced into an aqueous ZnSO_(4) electrolyte,a Zn/Zn symmetric cell shows durable and reversible Zn stripping/plating for 1500 h at a current density of 1 mA cm^(-2) and with an area capacity of 1 mAh cm^(-2).Zn/Na_(0.33)K_(0.1)V_(2)O_(5)·nH_(2)O full batteries exhibit a high capacity of 600 mAh g^(-1)at 0.1 A g^(-1) and long-term cycling performance for 5000 cycles,with a capacity of 200 mAh g^(-1) at 20 Ag^(-1).Ziqing Wang Miao Zhou Liping Qin Minghui Chen Zixian Chen Shan Guo Liangbing Wang Guozhao Fang Shuquan Liang 2022eScience2022,2,2:8
4The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5
5Dynamic temperature prediction of electronic equipment under high altitude long endurance conditions显示文摘Unmanned Aerial Vehicle(UAV) is developing towards the direction of High Altitude Long Endurance(HALE). This will have an important influence on the stability of its airborne electronic equipment using passive thermal management. In this paper, a multi-node transient thermal model for airborne electronic equipment is set up based on the thermal network method to predict their dynamic temperature responses under high altitude and long flight time conditions. Some relevant factors are considered into this temperature prediction model including flight environment,radiation, convection, heat conduction, etc. An experimental chamber simulating a high altitude flight environment was set up to survey the dynamic thermal responses of airborne electronic equipment in a UAV. According to the experimental measurement results, the multi-node transient thermal model is verified without consideration of the effects of flight speed. Then, a modified way about outside flight speed is added into the model to improve the temperature prediction performance. Finally, the corresponding simulation code is developed based on the proposed model. It can realize the dynamic temperature prediction of airborne electronic equipment under HALE conditions.Liping PANG Miao ZHAO Kun LUO Yongli YIN Zhou YUE 2018Chinese Journal of Aeronautics2018,31,6:4
6Tranexamic acid for acute intracerebral haemorrhage growth based on imaging assessment (TRAIGE): a multicentre, randomised, placebo- controlled trial显示文摘Background Studies show tranexamic acid can reduce the risk of death and early neurological deterioration after intracranial haemorrhage.We aimed to assess whether tranexamic acid reduces haematoma expansion and improves outcome in intracerebral haemorrhage patients susceptible to haemorrhage expansion.Methods We did a prospective,double-blind,randomised,placebo-controlled trial at 10 stroke centres in China.Acute supratentorial intracerebral haemorrhage patients were eligible if they had indication of haemorrhage expansion on admission imaging(eg,spot sign,black hole sign or blend sign),and were treatable within 8 hours of symptom onset.Patients were randomly assigned(1:1)to receive either tranexamic acid or a matching placebo.The primary outcome was intracerebral haematoma growth(>33% relative or>6 mL absolute)at 24 hours.Clinical outcomes were assessed at 90 days.Results Of the 171 included patients,124(72.5%)were male,and the mean age was 55.9±11.6 years.89 patients received tranexamic acid and 82 received placebo.The primary outcome did not differ significantly between the groups:36(40.4%)patients in the tranexamic acid group and 34(41.5%)patients in the placebo group had intracranial haemorrhage growth(OR 0.96,95% CI 0.52 to 1.77,p=0.89).The proportion of death was lower in the tranexamic acid treatment group than placebo group(8.1%vs 10.0%),but there were no significant differences in secondary outcomes including absolute intracranial haemorrhage growth,death and dependency.Conclusions Among patients susceptible to haemorrhage expansion treated within 8 hours of stroke onset,tranexamic acid did not significantly prevent intracerebral haemorrhage growth.Larger studies are needed to assess safety and efficacy of tranexamic acid in intracerebral haemorrhage patients.Jingyi Liu Ximing Nie Hongqiu Gu Qi Zhou Haixin Sun Ying Tan Dacheng Liu Lina Zheng Jiahui Zhao Yan Wang Yibin Cao Haomeng Zhu Yunpeng Zhang Lijin Yi Yuehua Pu Miao Wen Zhonghua Yang Shengjun Sun Wenzhi Wang Xingquan Zhao Liping Liu Yongjun Wang 2021Stroke & Vascular Neurology2021,6,2:3
7Design of novel NiSiAlY alloys in marine salt-spray environment:PartⅡ.Al-Ni-Si-Y thermodynamic dataset显示文摘The NiSiAlY material is a promising candidate to replace NiCrAlY,which can withstand the harsh saltspray conditions in marine environment.To efficiently design novel NiSiAlY alloys,this work establishes a thermodynamic dataset of the Al-Ni-Si-Y quaternary system using the CALPHAD(CALculation of PHAse Diagrams)approach.We employ this database to calculate and predict the phase constitutions and solidification behaviors of different NiSiAlY alloys concerning the content variations of Al and Si.We have further proposed the selection of the NiSiAlY alloys for serving in marine salt-spray environment with three constraints:(i)outstanding mechanical property;(ii)good high-temperature anti-oxidation;(iii)excellent corrosion resistance.This results in a compositional range of the NiSiAlY alloys with 1 wt%Kai Xu Keke Chang Miao Yu Dapeng Zhou Yong Du Liping Wang 2021Journal of Materials Science & Technology2021,,30:3

9Haemostatic therapy in spontaneous intracerebral haemorrhage patients with high-risk of haematoma expansion by CT marker: a systematic review and meta- analysis of randomised trials显示文摘Background and purpose Current randomised controlled trials(RCTs)showed an uncertain benefit of haemostatic therapy on preventing haematoma expansion and improving the outcome in patients with intracerebral haemorrhage(ICH).This meta-analysis aims to systematically evaluate the effect of haemostatic agents on the prevention of haemorrhage growth in patients with high-risk spontaneous ICH predicted by CT signs in RCTs.Methods A comprehensive search of PubMed,EMBASE and Cochrane library from 1 January 2005 to 30 June 2021 was conducted.RCTs that compared haemostatic agents with placebo for the treatment of spontaneous patients with ICH with high-risk haemorrhage growth were included.The primary endpoint was haematoma expansion at 24 hours.Other major endpoints of interest included 90-day functional outcome and mortality.Results The meta-analysis included four RCTs that randomised 2666 patients with ICH with high-risk haemorrhage growth.Haemostatic therapy reduced the rate of haematoma expansion at a marginally statistically significant level when compared with placebo(OR 0.84;95% CI 0.70 to 1.00;p=0.051).Subgroup analysis for patients with black hole sign on CT revealed a significant reduction of haematoma expansion with haemostatic therapy(OR 0.61;95% CI 0.39 to 0.94;p=0.03).However,both the primary analysis and subgroup analyses showed that haemostatic therapy could not reduce the rate of poor functional outcome(modified Rankin Scale>3)or death.Conclusions Haemostatic therapy showed a marginally significant benefit in reducing early haematoma expansion in patients with high-risk spontaneous ICH predicted by markers on CT scan.However,no significant improvement in functional outcome or reduction of mortality was observed.Ximing Nie Jingyi Liu Dacheng Liu Qi Zhou Wanying Duan Yuehua Pu Zhonghua Yang Miao Wen Haixin Sun Wenzhi Wang Shengjun Sun Hongqiu Gu Liping Liu 2021Stroke & Vascular Neurology2021,6,2:2
10Geniposide protects human neuroblastoma SH-SY5Y cells against corticosterone-induced injury显示文摘In vitro cultured human neuroblastoma SH-SY5Y cells were pretreated with 50 or 5 μg/mL geniposide for 12 hours and exposed to 400 μmol/L corticosterone. Corticosterone exposure in cultures not pretreated with geniposide resulted in inhibited cell growth, reduced cell survival, and increased P53 and P21 protein expression. However, in geniposide pretreated SH-SY5Y cells, cell viability and the number of cells in the G2 phase of the cell cycle were significantly increased, P21 and P53 protein expression was reduced, and cell apoptosis was inhibited following corticosterone exposure. These results indicate that geniposide can protect SH-SY5Y cells against high-dose corticosterone-induced injury.Liping Chen Fawei Wang Miao Geng Hongyan Chen Dongmei Duan 2011Neural Regeneration Research2011,6,21:2

13Effects and interaction of temperature and relative humidity on the trend of influenza prevalence:A multi-central study based on 30 provinces in China's Mainland from 2013 to 2018显示文摘Background:Evidence is inefficient about how meteorological factors influence the trends of influenza transmission in different regions of China.Methods:We estimated the time-varying reproduction number(Rt)of influenza and explored the impact of temperature and relative humidity on Rt using generalized additive quasi-Poisson regression models combined with the distribution lag non-linear model(DLNM).The effect of temperature and humidity interaction on Rt of influenza was explored.The multiple random-meta analysis was used to evaluate region-specific association.The excess risk(ER)index was defined to investigate the correlation between Rt and each meteorological factor with the modification of seasonal and regional characteristics.Results:Low temperature and low relative humidity contributed to influenza epidemics on the national level,while shapes of merged cumulative effect plots were different across regions.Compared to that of median temperature,the merged RR(95%CI)of low tem-perature in northern and southern regions were 1.40(1.24,1.45)and 1.20(1.14,1.27),respectively,while those of high temperature were 1.10(1.03,1.17)and 1.00(0.95,1.04),respectively.There were negative interactions between temperature and relative humidity on national(SI=0.59,95%CI:0.57e0.61),southern(SI=0.49,95%CI:0.17e0.80),and northern regions(SI=0.59,95%CI:0.56,0.62).In general,with the increase of the change of the two meteorological factors,the ER of Rt also gradually increased.Conclusions:Temperature and relative humidity have an effect on the influenza epidemics in China,and there is an interaction between the two meteorological factors,but the effect of each factor is heterogeneous among regions.Meteorological factors may be considered to predict the trend of influenza epidemic.Yi Yin Miao Lai Sijia Zhou Ziying Chen Xin Jiang Liping Wang Zhongjie Li Zhihang Peng 2023Infectious Disease Modelling2023,8,3:1

19Th17/Treg balance and factors related to autoimmune hepatitis显示文摘Background:Although Th17 cells and regulatory T cells play critical roles in autoimmune hepatitis,the balance between them in acute and chronic immune hepatitis is not well‐studied.The objective of this study was to explore the role of Th17/Treg balance in autoimmune hepatitis.Methods:Thirty female Wistar rats were randomly divided into the following three groups:acute model(AC),chronic model(CC),and healthy control(HC).Aspartate aminotransferase,alanine aminotransferase,and bilirubin levels were measured.Peripheral blood interleukin(IL)‐17,IL‐6,IL‐10,and transforming growth factor‐βcytokine levels were also assessed.Flow cytometry was used to detect changes in the Th17 cell and Treg cell frequency,and the Th17/Treg ratio was calculated.Results:The frequency of Th17 cells and Treg cells were both increased(p<0.05)and the Th17/Treg ratio was higher in the AC group compared with those in the HC group(p<0.05).Th17 cell levels were significantly lower and Treg cell levels were significantly higher in the CC group,compared with those in the AC group(p<0.05).In addition,the Th17/Treg ratio was lower in the CC group compared with that in the HC group(p<0.05).Conclusion:The Th17/Treg ratio was increased in the acute immune liver injury model and decreased in the chronic liver injury model.Th17/Treg imbalance may play a critical role in liver injury occurrence and development.Miao Xue Junshuai Feng Aimin Yang Liping Gao Xuebin Peng Ni Jiang Xiaorong Mao 2022Rheumatology & Autoimmunity2022,2,4:1
20转染AP-2α基因对结肠癌SW620细胞增殖及凋亡的影响(英文)显示文摘Objective:We investigated the effects of exogenous AP-2α gene on SW620 cell cycle, apoptosis and proliferation. Methods:The Plasmid pcDNA3.1(+)-AP-2α was transfected into colorectal carcinoma SW620 cells line by liposome mediation for transient expression. After AP-2α transfected SW620 cells, the exogenous AP-2α mRNA and protein express were determined by the method of Real-time PCR and Western blot. In order to elucidate the effect of expression of exogenous AP-2α gene on the colorectal cancer cell SW620, the proliferation rates were analyzed by growth curves for cells including SW620, pcDNA3.1(+)/SW620 and pcDNA3.1(+)-AP-2α/SW620. At same time, the apoptotic rate of cells and the cell cycle analysis were also tested by flow cytometry. Results: The mRNA and protein expressions of AP-2α gene could be enhanced by transfecting of pcDNA3.1(+)-AP-2α recombinant plasmid into SW620 cell. The cell growth rates of SW620 cells transfected with pcDNA3.1(+)/AP-2α were slower than those transfected with pcDNA3.1(+) or untransfected. The apoptotic rates were increased compared with pcDNA3.1(+)/SW620 and SW620 (P<0.05), which indicated that over-expression of AP-2α gene could efficiently inhibit the growth of SW620 cells and induce apoptosis. FCM analyses indicated that the cells being arrested in G1 phase. Conclusion: AP-2α gene can be efficiently transfected into SW620 cells and over-expression AP-2α protein in the transfected cells. AP-2α induces G1 arrest and apoptosis, suppressive effect on cell growth.Yeping Du Liping Xu Jinhua Miao Chunmei Wu Lili Yin Niuliang Cheng 2010The Chinese-German Journal of Clinical Oncology2010,9,4:1
