| 1 | Pandemic of the aging society—sporadic cerebral small vessel disease显示文摘Age-related sporadic cerebral small vessel disease(CSVD)has gained increasing attention over the past decades because of its increasing prevalence associated with an aging population.The widespread application of and advances in brain magnetic resonance imaging in recent decades have significantly increased researchers’understanding in the in vivo evolution of CSVD,its impact upon the brain,its risk factors,and the mechanisms that explain the various clinical manifestation associated with sporadic CSVD.In this review,we aimed to provide an update on the pathophysiology,risk factors,biomarkers,and the determinants and spectrum of the clinical manifestation of sporadic CSVD. | Alexander Yuk Lun Lau Bonaventure Yiu Ming Ip Ho Ko Bonnie Yin Ka Lam Lin Shi Karen Ka Yan Ma Lisa Wing Chi Au Yannie Oi Yan Soo Thomas Wai Hong Leung Adrian Wong Vincent Chung Tong Mok | 2021 | Chinese Medical Journal2021，，2： | 3 |
| 2 | 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 |

| 4 | 深部脑刺激治疗帕金森病:下丘脑核团靶点定位的解剖与生理对比研究显示文摘目的 探讨脑深部STN刺激靶点时MRI直接定位法和MER术中导引定位法的解剖学偏差。方法 本组5例帕金森病患者,分别表现为运动迟缓、步态不稳及躯干症状,共安放6例次微电极。结果 采用MRI直接定位法和MER术中导引定位法,其定位靶点的平均偏差距离是1.25mm,尽管该偏差值较小,但是,基于影像学的立体定向法只能将刺激电极定位于距离靶点几毫米的范围内。结论 电生理学方法(MER)对于调整和确定靶点位置至关重要。MER术中导引定位法有助于手术的完全成功。 | Wai.S Poon Danny TM Chan XL Zhu Vincent CT Mok YL Chan | 2002 | 中华神经外科疾病研究杂志2002，1，2： | 2 |
| 5 | 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 |

| 13 | The potential development of drug resistance in rheumatoid arthritis patients identified with p53 mutations显示文摘Rheumatoid arthritis(RA)is a chronic inflammatory disease characterized by cartilage and bone damage with the presence of pannus formation which causes uncontrollable proliferation and invasion of fibroblast-like synoviocytes(FLS).Since rheumatoid arthritis is a chronic disorder,the patients normally need to undergo prolonged antirheumatic treatment with the use of disease-modifying antirheumatic drugs(DMARDs),steroids,and nonsteroidal anti-inflammatory drugs(NSAIDs).The efficacy of such long-term pharmaceutical intervention can be significantly affected by the development of drug resistance.The pathological relationship between rheumatoid arthritis and cancer hinted that some chemotherapeutic drugs,such as methotrexate(MTX),could be used for RA treatment.This idea was reinforced by the analysis of mutations in p53 tumor suppressor gene.Around 50%of p53 somatic mutations observed from various cancers are also identified in the synovium of RA patients1(Fig.1A).Of note,the hyperplastic synovium in RA with overexpressed p53 mutants contributed to the destruction of joints in patients with erosive RA. | Congling Qiu Joyce Tsz Wai Chan David Wei Zhang Io Nam Wong Yaling Zeng Betty Yuen Kwan Law Simon Wing Fai Mok Ivo Ricardo De Seabra Rodrigues Dias Wenfeng Liu Liang Liu Vincent Kam Wai Wong | 2023 | Genes & Diseases2023，10，6： | 0 |

| 15 | Genome sequencing reveals the role of rare genomic variants in Chinese patients with symptomatic intracranial atherosclerotic disease显示文摘Objectives The predisposition of intracranial atherosclerotic disease(ICAD)to East Asians over Caucasians infers a genetic basis which,however,remains largely unknown.Higher prevalence of vascular risk factors(VRFs)in Chinese over Caucasian patients who had a stroke,and shared risk factors of ICAD with other stroke subtypes indicate genes related to VRFs and/or other stroke subtypes may also contribute to ICAD.Methods Unrelated symptomatic patients with ICAD were recruited for genome sequencing(GS,60-fold).Rare and potentially deleterious single-nucleotide variants(SNVs)and small insertions/deletions(InDels)were detected in genome-wide and correlated to genes related to VRFs and/or other stroke subtypes.Rare aneuploidies,copy number variants(CNVs)and chromosomal structural rearrangements were also investigated.Lastly,candidate genes were used for pathway and gene ontology enrichment analysis.Results Among 92 patients(mean age at stroke onset 61.0±9.3 years),GS identified likely ICAD-associated rare genomic variants in 54.3%(50/92)of patients.Forty-eight patients(52.2%,48/92)had 59 rare SNVs/InDels reported or predicted to be deleterious in genes related to VRFs and/or other stroke subtypes.None of the 59 rare variants were identified in local subjects without ICAD(n=126).31 SNVs/InDels were related to conventional VRFs,and 28 were discovered in genes related to other stroke subtypes.Our study also showed that rare CNVs(n=7)and structural rearrangement(a balanced translocation)were potentially related to ICAD in 8.7%(8/92)of patients.Lastly,candidate genes were significantly enriched in pathways related to lipoprotein metabolism and cellular lipid catabolic process.Conclusions Our GS study suggests a role of rare genomic variants with various variant types contributing to the development of ICAD in Chinese patients. | Mengmeng Shi Xinyi Leng Ying Li Zihan Chen Ye Cao Tiffany Chung Bonaventure YM Ip Vincent HL Ip Yannie OY Soo Florence SY Fan Sze Ho Ma Karen Ma Anne Y Y Chan Lisa WC Au Howan Leung Alexander Y Lau Vincent CT Mok Kwong Wai Choy Zirui Dong Thomas W Leung | 2022 | Stroke & Vascular Neurology2022，7，3： | 0 |
| 16 | The host-targeting compound peruvoside has a broad-spectrum antiviral activity against positive-sense RNA viruses显示文摘Positive-sense RNA viruses modify intracellular calcium stores,endoplasmic reticulum and Golgi apparatus(Golgi)to generate membranous replication organelles known as viral factories.Viral factories provide a conducive and substantial enclave for essential virus replication via concentrating necessary cellular factors and viral proteins in proximity.Here,we identified the vital role of a broadspectrum antiviral,peruvoside in limiting the formation of viral factories.Mechanistically,we revealed the pleiotropic cellular effect of Src and PLC kinase signaling via cyclin-dependent kinase 1 signaling leads to Golgi-specific brefeldin A-resistance guanine nucleotide exchange factor 1(GBF1)phosphorylation and Golgi vesiculation by peruvoside treatment.The ramification of GBF1 phosphorylation fosters GBF1 deprivation consequentially activating downstream antiviral signaling by dampening viral factories formation.Further investigation showed signaling of ERK1/2 pathway via cyclin-dependent kinase 1 activation leading to GBF1 phosphorylation at Threonine 1337(T1337).We also showed 100%of protection in peruvoside-treated mouse model with a significant reduction in viral titre and without measurable cytotoxicity in serum.These findings highlight the importance of dissecting the broad-spectrum antiviral therapeutics mechanism and pave the way for consideration of peruvoside,host-directed antivirals for positive-sense RNA virus-mediated disease,in the interim where no vaccine is available. | Kan Xing Wu Thinesshwary Yogarajah Marcus Wing Choy Loe Parveen Kaur Regina Ching Hua Lee Chee Keng Mok Yi Hao Wong Patchara Phuektes Li Sze Yeo Vincent T.K.Chow Yong Wah Tan Justin Jang Hann Chu | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 0 |
| 17 | HM30181A,a potent P-glycoprotein inhibitor,potentiates the absorption and in vivo antitumor efficacy of paclitaxel in an orthotopic brain tumor model显示文摘Objective:Delivery of chemotherapeutic drugs to the brain has remained a major obstacle in the treatment of glioma,owing to the presence of the blood-brain barrier and the activity of P-gp,which pumps its substrate back into the systemic circulation.The aim of the present study was to develop an intravenous formulation of HM30181 A(HM)to inhibit P-gp in the brain to effectively deliver paclitaxel(PTX)for the treatment of malignant glioma.Methods:Two formulations of solubilized HM were designed on the basis of different solid dispersion strategies:i)spray-drying[polyvinlypyrrolidone(PVP)-HM]and ii)solvent evaporation[HP-β-cyclodextrin(cyclodextrin)-HM].The P-gp inhibition of these 2 formulations was assessed on the basis of rhodamine 123 uptake in cancer cells.Blood and brain pharmacokinetic parameters were also determined,and the antitumor effect of cyclodextrin-HM with PTX was evaluated in an orthotopic glioma xenograft mouse model.Results:Although both PVP-HM and cyclodextrin-HM formulations showed promising P-gp inhibition activity in vitro,cyclodextrin-HM had a higher maximum tolerated dose in mice than did PVP-HM.Pharmacokinetic study of cyclodextrin-HM revealed a plasma concentration plateau at 20 mg/kg,and the mice began to lose weight at doses above this level.Cyclodextrin-HM(10 mg/kg)administered with PTX at 10 mg/kg showed optimal antitumor activity in a mouse model,according to both tumor volume measurement and survival time(P<0.05).Conclusions:In a mouse orthotopic brain tumor model,the intravenous co-administration of cyclodextrin-HM with PTX showed potent antitumor effects and therefore may have potential for glioma therapy in humans. | Wu Zeng Betty Yuen Kwan Law Vincent Kam Wai Wong Denise So Bik Chan Simon Wing Fai Mok Joyce Jia Ying Gao Rebecca Ka Yan Ho Xu Liang Jia Hao Li Ming Tsung Lee Weng Li Yoon Michael P Smolinski Johnson Yiu Nam Lau Christopher Wai Kei Lam Manson Fok | 2020 | Cancer Biology & Medicine2020，17，4： | 0 |
