| 1 | Guidelines for evaluation and management of cerebral collateral circulation in ischaemic stroke 2017显示文摘Collateral circulation plays a vital role in sustaining blood flow to the ischaemic areas in acute,subacute or chronic phases after an ischaemic stroke or transient ischaemic attack.Good collateral circulation has shown protective effects towards a favourable functional outcome and a lower risk of recurrence in stroke attributed to different aetiologies or undergoing medical or endovascular treatment.Over the past decade,the importance of collateral circulation has attracted more attention and is becoming a hot spot for research.However,the diversity in imaging methods and criteria to evaluate collateral circulation has hindered comparisons of findings from different cohorts and further studies in exploring the clinical relevance of collateral circulation and possible methods to enhance collateral flow.The statement is aimed to update currently available evidence and provide evidence-based recommendations regarding grading methods for collateral circulation,its significance in patients with stroke and methods under investigation to improve collateral flow. | Liping Liu Jing Ding Xinyi Leng Yuehua Pu Li-An Huang Anding Xu Ka Sing Lawrence Wong Xin Wang Yongjun Wang 无 | 2018 | Stroke & Vascular Neurology2018，3，3： | 37 |
| 2 | Perfluorooctane sulfonate(PFOS) and related fluorochemicals in chicken egg in China显示文摘The ubiquitous occurrence of perfluorinated compounds(PFCs) in environmental samples has drawn much attention.Recent human exposure studies found relatively high perfluorooctane sulfonate(PFOS) concentrations in blood samples from several cities in China when compared with other countries.The objectives of the present study were:(1) to measure PFC concentrations and compositions in chicken egg samples from local markets in China;and(2) to conduct a preliminary human health risk assessment of egg consumption.Eight pooled egg samples from eight locations were analyzed for 11 PFCs.The results showed that close to 100% of the PFOS in the egg was distributed in egg yolk and PFOS was not detected in egg white(<0.08 ng/g wet weight,w/w).Of the perfluoroalkylsulfonates,only PFOS was detected in all egg samples,while of the perfluoroalkylcarboxylates,perfluoroundecanoic acid(PFUnDA) was detected in all samples,followed by perfluorooctanoate(PFOA)(75% occurrence) and perfluorodecanoic acid(PFDA)(50% occurrence).PFOS concentrations in egg ranged from 45.0 to 86.9 ng/g w/w.The results suggested that current concentrations of PFOS in domestic chicken eggs are unlikely to cause immediate harm to Chinese populations. | WANG Yuan YEUNG Leo Wai Yin YAMASHITA Nobuyoshi TANIYASU Sachi SO Man Ka Margaret B.

| 3 | Phase Ⅰ/Ⅱ randomized controlled trial of autologous bone marrow-derived mesenchymal stem cell therapy for chronic stroke显示文摘AIM To examine the safety and efficacy of mesenchymal stem cell(MSC) therapy for intracerebral haemorrhage with neurological dysfunctions for a year.METHODS MSC were ex vivo expanded from 29 mL(17-42 mL) autologous bone marrow. Patients were randomized to have two intravenous injections of autologous MSC or placebos in four weeks apart. Neurological functions and clinical outcomes were monitored before treatment and at 12^(th), 16^(th), 24^(th), 36^(th) and 60^(th) week upon completion of^(th)e treatment. RESULTS A mean of 4.57 × 10~7(range: 1.43 × 10~7-8.40 × 10~7) MSC per infusion was administered accounting to 8.54 × 10~5(2.65 × 10~5-1.45 × 10~6) per kilogram body weight in two occasions. There was neither adverse event at time of administration nor sign of de novo tumour development among patients after monitoring for a year post MSC therapy. Neuro-restoration and clinical improvement in terms of modified Barthel index, functional independence measure and extended Glasgow Outcome Scale were evident among patients having MSC therapy compared to patients receiving placebos. CONCLUSION Intravenous administration of autologous bone marrowderived MSC is safe and has the potential of improving neurological functions in chronic stroke patients with severe disability. | Kam Sze Tsang Chi Ping Stephanie Ng Xian Lun Zhu George Kwok Chu Wong Gang Lu Anil Tejbhan Ahuja Ka Sing Lawrence Wong Ho Keung Ng Wai Sang Poon | 2017 | World Journal of Stem Cells2017，9，8： | 3 |

| 5 | Atrophy of the left dorsolateral prefrontal cortex is associated with poor performance in verbal fluency in elderly poststroke women显示文摘This study aimed to investigate the association between atrophy in the prefrontal cortex with executive function and verbal fluency in elderly male and female patients poststroke.Thirty elderly female patients with non-aphasic ischemic stroke aged ≥ 60 years and 30 age-matched non-aphasic male patients with ischemic stroke were recruited.Automatic magnetic resonance imaging segmentation was used to assess the volume of the whole prefrontal cortex,along with its subdivisions:anterior cingulate cortex,orbitofrontal cortex and dorsolateral prefrontal cortex.The Semantic Verbal Fluency Test was administered at 3 and 15 months poststroke.At 3 months poststroke,left dorsolateral prefrontal cortex volume was significantly correlated with Verbal Fluency Test score in female patients only(partial coefficient = 0.453,P = 0.045),after controlling for age,education,diabetes,neurological deficit,white matter lesions volume,as well as the location and volume of infarcts.At 15 months poststroke,there remained a significant association between the left dorsolateral prefrontal cortex volume and Verbal Fluency Test(partial coefficient = 0.661,P = 0.001) and between the left prefrontal cortex volume and Verbal Fluency Test(partial coefficient = 0.573,P = 0.004) in female patients after the same adjustments.These findings indicate that atrophy of the left dorsolateral prefrontal cortex contributes to the impairment of verbal fluency in elderly female patients with stroke.Sex differences may be present in the neuropsychological mechanisms of verbal fluency impairment in patients with stroke. | Yang-Kun Chen Wei-Min Xiao Defeng Wang Lin Shi Winnie CW Chu Vincent CT Mok Ka Sing Wong Gabor S Ungvari Wai Kwong Tang | 2013 | Neural Regeneration Research2013，8，4： | 2 |

| 7 | Risk stratification in symptomatic intracranial atherosclerotic disease with conventional vascular risk factors and cerebral haemodynamics显示文摘Background and purpose Symptomatic intracranial atherosclerotic stenosis(sICAS)is associated with a considerable risk of recurrent stroke despite contemporarily optimal medical treatment.Severity of luminal stenosis in sICAS and its haemodynamic significance quantified with computational fluid dynamics(CFD)models were associated with the risk of stroke recurrence.We aimed to develop and compare stroke risk prediction nomograms in sICAS,based on vascular risk factors and these metrics.Methods Patients with 50%-99%sICAS confirmed in CT angiography(CTA)were enrolled.Conventional vascular risk factors were collected.Severity of luminal stenosis in sICAS was dichotomised as moderate(50%-69%)and severe(70%-99%).Translesional pressure ratio(PR)and wall shear stress ratio(WSSR)were quantified via CTA-based CFD modelling;the haemodynamic status of sICAS was classified as normal(normal PR&WSSR),intermediate(otherwise)and abnormal(abnormal PR&WSSR).All patients received guideline-recommended medical treatment.We developed and compared performance of nomograms composed of these variables and independent predictors identified in multivariate logistic regression,in predicting the primary outcome,recurrent ischaemic stroke in the same territory(SIT)within 1 year.Results Among 245 sICAS patients,20(8.2%)had SIT.The D2H2A nomogram,incorporating diabetes,dyslipidaemia,haemodynamic status of sICAS,hypertension and age≥50 years,showed good calibration(P for Hosmer-Lemeshow test=0.560)and discrimination(C-statistic 0.73,95%CI 0.60 to 0.85).It also had better performance in risk reclassification and provided larger net benefits in decision curve analysis,compared with nomograms composed of conventional vascular risk factors only,and plus the severity of luminal stenosis in sICAS.Sensitivity analysis in patients with anterior-circulation sICAS showed similar results.Conclusions The D2H2A nomogram,incorporating conventional vascular risk factors and the haemodynamic significance of sICAS as assessed in CFD models,could be a useful tool to stratify sICAS patients for the risk of recurrent stroke under contemporarily optimal medical treatment. | Xuan Tian Hui Fang Linfang Lan Hing Lung Ip Jill Abrigo Haipeng Liu Lina Zheng Florence S Y Fan Sze Ho Ma Bonaventure Ip Bo Song Yuming Xu Jingwei Li Bing Zhang Yun Xu Yannie O Y Soo Vincent Mok Ka Sing Wong Thomas W Leung Xinyi Leng | 2023 | Stroke & Vascular Neurology2023，8，1： | 2 |
