| 1 | Endovascular 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 | 2022 | Stroke & Vascular Neurology2022，7，3： | 10 |
| 2 | Tranexamic 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 | 2021 | Stroke & Vascular Neurology2021，6，2： | 3 |
| 3 | A novel akermanite/poly (lactic-co-glycolic acid) porous composite scaffold fabricated via a solvent casting-particulate leaching method improved by solvent self-proliferating process显示文摘Desirable scaffolds for tissue engineering should be biodegradable carriers to supply suitablemicroenvironments mimicked the extracellular matrices for desired cellular interactions and to providesupports for the formation of new tissues. In this work, a kind of slightly soluble bioactiveceramic akermanite (AKT) powders were aboratively selected and introduced in the PLGA matrix,a novel L-lactide modified AKT/poly (lactic-co-glycolic acid) (m-AKT/PLGA) composite scaffold wasfabricated via a solvent casting-particulate leaching method improved by solvent self-proliferatingprocess. The effects of m-AKT contents on properties of composite scaffolds and on MC3T3-E1 cellularbehaviors in vitro have been primarily investigated. The fabricated scaffolds exhibited threedimensionalporous networks, in which homogenously distributed cavities in size of 300–400 lmwere interconnected by some smaller holes in a size of 100–200 lm. Meanwhile, the mechanicalstructure of scaffolds was reinforced by the introduction of m-AKT. Moreover, alkaline ionic productsreleased by m-AKT could neutralize the acidic degradation products of PLGA, and the apatitemineralizationability of scaffolds could be largely improved. More valuably, significant promotionson adhesion, proliferation, and differentiation of MC3T3-E1 have been observed, which implied thecalcium, magnesium and especially silidous ions released sustainably from composite scaffoldscould regulate the behaviors of osteogenesis-related cells. | Yao Deng Mengjiao Zhang Xianchun Chen Ximing Pu Xiaoming Liao Zhongbing Huang Guangfu Yin | 2017 | Regenerative Biomaterials2017，4，4： | 3 |
| 4 | Haemostatic 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 | 2021 | Stroke & Vascular Neurology2021，6，2： | 2 |

| 11 | MBG/PGA-PCL composite scaffolds provide highly tunable degradation and osteogenic features显示文摘It remains a challenge to achieve satisfactory balance between biodegradability and osteogenic capacity in biosynthetic bone grafts.In this study,we aimed to address this challenge by incorporating mesoporous bioactive glass(MBG)into poly(caprolactone-co-glycolide)(PGA-PCL)at gradient ratios.MBG/PGA-PCL(PGC/M)scaffolds with MBG incorporation ratio at 0,10%,25%and 40%(PGC/M0-40)were synthesized using a modified solvent casting-particulate leaching method,and their physiochemical and biological properties were comprehensively evaluated.PGC/M scaffolds exhibited highly perforated porous structure with a large-pore size of 300-450μm,with ordered MBGs of around 6.0 nm mesopores size uniformly dispersed.The increase in MBG incorporation ratio significantly improved the scaffold surface hydrophilicity,apatite-formation ability and pH stability,increased the weight loss rate while insignificantly influenced the molecular chains degradation of PGA-PCL component,and facilitated the attachment,spreading,viability and proliferation of rat bone marrow stromal cells(rBMSCs)on scaffolds.Moreover,rBMSCs cultured on PGC/M10-40 scaffolds demonstrated enhanced ALP activity and osteogenesis-related gene expression in a MBG dose-dependent manner as compared with those cultured on PGC/M0 scaffolds.When implanted to the rat cranial bone defect,PGC/M25 and PGC/M40 scaffolds induced significantly better bone repair as compared to PGC/M0 and PGC/M10 scaffolds.Besides,the biodegradability of PGC/M scaffolds correlated with the MBG incorporation ratio.These data suggested this novel PGC/M scaffolds as promising bone repair biomaterial with highly tunable hydrophilicity,bioactivity,cytocompatibility,osteogenic activity as well as biodegradability. | Jiangfeng Li Chunyi Wang Guoxing Gao Xing Yin Ximing Pu Bing Shi Yang Liu Zhongbing Huang Juan Wang Jingtao Li Guangfu Yin | 2022 | Bioactive Materials2022，7，9： | 0 |
| 12 | Fabrication of carboxylic graphene oxide-composited polypyrrole film for neurite growth under electrical stimulation显示文摘An aligned composite film was fabricated via the deposition of carboxylic graphe ne oxide(C-GO)and polypyrrole(PPy)nano particles on alig ned poly(L-lactic acid)(PLLA)fiber-films(named as C-GO/PPy/PLLA),which has the core(PLLA)-sheath(C-GO/PPy)structure,and the composition of C-GO(~4.8 wt.%of PPy sheath)significantly enhanced the tensile strength and the conductivity of the PPy/PLLA film?Especially,after 4 weeks of immersion in the PBS solution,the conductivity and the tensile strength of CGO/PPy/PLLA films still remained-6.10 S/cm and 28.9 MPa,respectively,which could meet the need of the sustained electrical stimulation(ES)therapy for nerve repair.Moreover,the neurite length and the neurite alignment were significantly in creased through exerting ES on C-GO/PPy/PLLA films due to their sustained conductivity in the fluid of cell culture.These results indicated that C-GO/PPy/PLLA with sustained conductivity and mechanical property possessed great potential of nerve repair by exerting lasting-ES. | Chaoyuan LIU Zhongbing HUANG Ximing PU Lei SHANG Guangfu YIN Xianchun CHEN Shuang CHENG | 2019 | Frontiers of Materials Science2019，13，3： | 0 |
