1Synthesis of an AIE-active fluorogen and its application in cell imaging显示文摘A fluorogen named 1-decyl-1-methyl-2,5-bis{4-[(N,N-diethylamino)methyl]phenyl}-3,4-diphenylsilole (3) was synthesized. It emitted weakly as isolated molecule but strongly as supramolecular aggregate, showing a characteristic behavior of aggregation-induced emission (AIE). The molecules of 3 formed highly emissive nanoparticles in aqueous media, which quickly and selectively marked cytoplasm of HeLa cells and posed no toxicity to the living cells. The fluorogen is thus a promising candidate mate-rial for cell imaging as a sensitive, selective and cytocompatible biosensor.LAM Jacky Wing Yip FAISAL Mahtab NG Ka Ming LUO Kathy Qian 2009Science China Chemistry2009,52,1:12
2人口统计学因素、心理特征对创业意愿的影响——一项来自中国各高校的实证研究显示文摘根据选取的335名在校大学生和研究生,探讨4种人口统计学因素[包括性别、年龄、家庭背景、学院(经管类和非经管类)]及6种心理特征(包括控制点、成就需求、模糊容忍度、风险偏好、自信和创新的)对创业意愿的影响。结果表明:成就需求、模糊容忍度、自信和创新在区分企业家和非企业家时具有重要意义,而控制点和风险偏好没有表现出显著差异。除这6种心理特征外,研究结果还强调了家庭背景和学院在创业意愿预测中起决定作用。这项研究对我国教育体制政策制定产生了巨大影响,同时弥补了中国样本的缺失。周劲波 汤潇 Wing Lam 2018广西社会科学2018,,3:8
3硝基苯衍生物结构与其淬灭聚(2,5-二戊氧基对亚苯基亚乙炔基)荧光效率的关系显示文摘The poly(2,5-dipentyloxy-para-phenylene ethynylene)(P) was synthesized by Pd-catalyzed Sonogashira coupling reaction.Due to causing energy transfer between the nitrobenzene’s quenchers and the polymer chains through the charge-transfer interaction,the fluorescence quenched properties of P varied obviously with the para-substituting group’s structure in the nitrobenzene derivatives.The fluorescence quenching efficiency of quenchers improved with increasing of electron repulsion capability of the para-substituting group.The fluorescence quenching efficiency increased nonlinearly with the concentration of the quenchers and had,however,no relation with the quenching time.徐宏丽 佟斌 石建兵 刘旸 田旭玲 董宇平 LAM Jacky Wing Yip 唐本忠 2007高分子学报2007,17,3:8
4HYPERBRANCHED CONJUGATIVE MACROMOLECULES CONSTRUCTED FROM TRIPLE-BOND BUILDING BLOCKS显示文摘Polycyclotrimerization and polycoupling of acetylenic monomers respectively furnish hyperbranched polyarylenes and polyynes with high molecular weights (up to 1 × 106) in high yields (up to 99.9%). The polymers possess low intrinsic viscosities and high thermal stabilities, losing little of their weights when heated to > 400℃. Upon pyrolysis at > 800℃, the polymers graphitize with high char yields (up to 86%). Hyperbranched polyarylenes efficiently emit deep-blue to blue-green lights with fluorescence quantum yields up to 98% and strongly attenuate intense laser pulses with optical power-limiting performances superior to that of C60, a well-known optical limiter. Poly(alkenephenylenes), poly(aroylarylenes) and polyynes are readily cross-linkable by UV irradiation, serving as excellent photoresist materials for the generation of patterns with nanometer resolution. Thin films of hyperbranched polyynes exhibit very high refractive indexes (n up to 1.86). The internal and terminal acetylene moieties of the polyynes readily form complexes with cobalt carbonyls, which can be transformed into soft ferromagnetic ceramics with high magnetic susceptibilities (Ms up to ca. 118 emu/g) and near-zero magnetic losses.Matthias HaeuBler Hong-chen Dong Jacky Wing Yip Lam Rong-hua Zheng An-jun Qin Ben-zhong Tang 2005Chinese Journal of Polymer Science2005,23,6:7
5Profiles and removal efficiency of polycyclic aromatic hydrocarbons by two different types of sewage treatment plants in Hong Kong显示文摘Sewage discharge could be a major source of polycyclic aromatic hydrocarbons(PAHs) in the coastal waters. Stonecutters Island and Shatin Sewage Treatment Works(SCISTW and STSTW)in Hong Kong, adopted chemically enhanced primary treatment and biological treatment,respectively. This study aimed at(1) determining the removal efficiencies of PAHs,(2) comparing the capabilities in removing PAHs, and(3) characterizing the profile of each individual PAHs, in the two sewage treatment plants(STPs). Quantification of 16 PAHs was conducted by a Gas Chromatography. The concentrations of total PAHs decreased gradually along the treatment processes(from 301 ± 255 and 307 ± 217 ng/L to 14.9 ± 12.1 and 63.3 ± 54.1 ng/L in STSTW and SCISTW, respectively). It was noted that STSTW was more capable in removing total PAHs than SCISTW with average total removal efficiency 94.4% ± 4.12% vs. 79.2% ± 7.48%(p < 0.05). The removal of PAHs was probably due to sorption in particular matter, confirmed by the higher distribution coefficient of individual and total PAHs in solid samples(dewatered sludge contained92.5% and 74.7% of total PAHs in SCISTW and STSTW, respectively) than liquid samples(final effluent-total contained 7.53% and 25.3% of total PAHs in STSTW and SCISTW, respectively).Despite the impressive capability of STSTW and SCISTW in removing PAHs, there was still a considerable amount of total PAHs(1.85 and 39.3 kg/year, respectively for the two STPs) being discharged into Hong Kong coastal waters, which would be an environmental concern.Yu Bon Man Ka Lai Chow Zhang Cheng Wing Yin Mo Yung Hau Chan James Chung Wah Lam Frankie Tat Kwong Lau Wing Cheong Fung Ming Hung Wong 2017Journal of Environmental Sciences2017,29,3:5

9Intravenous fluid selection rationales in acute clinical management显示文摘BACKGROUND: Intravenous fluid(IVF) is commonly used in acute clinical management. This study aimed to review the choice and primary considerations in IVF prescriptions and to evaluate the adequacy of guidelines and trainings on it in the New Territories West Cluster(NTWC) of Hong Kong.METHODS: This is a descriptive study based on data collected from an online survey. Data were processed by SPSS for statistical analysis. This study focused on a general description and doctor-nurse between group comparison. Participants were asked the choice of IVF for nine acute clinical scenarios and provide reason. A 1–10 scale was used to assess the sufficiency of guideline, training and information, and time for revision on IVF prescription.RESULTS: 0.9% sodium chloride was the most familiar IVF(36%), followed by 5% Dextrose solution(26%). In the nine scenarios, the most chosen IVF was 0.9% sodium chloride(37%–61%). There was significant difference in the choice of IVF between doctors and nurses in 7 cases. The second most chosen IVF for doctors was Plasma-Lyte A while that for nurses was Gelofusine. Departmental practice was the most chosen reason to account for the prescription. The adequacy of guideline, information and training, and time for revision was rated 5. Doctors had significantly more time at work than nurses to update knowledge in IVF prescription(5.41 versus 4.57).CONCLUSION: 0.9% sodium chloride was mostly chosen. The choice of IVF was mainly based on departmental practice. Adequacy of guideline, information and training, and time for revision on IVF prescription were average, indicating significant training deficit.Wing Yan Shirley Cheung Wai Kwan Cheung Chun Ho Lam Yeuk Wai Chan Hau Ching Chow Ka Lok Cheng Yau Hang Wong Chak Wah Kam 2018World Journal of Emergency Medicine2018,9,1:3
10英国新创企业奖励计划及其纳入主流创业教育的实践和启示显示文摘英国于2001年正式启动的'新创企业奖励计划'(NES)项目,是英国政府为突显高等教育机构和企业机构在促进弱势地区创业活动中的作用而采取的重要举措之一。该项目推出以来,NES毕业生自主创办的企业平均存活率达到了85%,NES所扶持的创业公司的数量以及毕业生所获得的区级和国家级奖项全都高于全国平均水平,取得了令人瞩目的成绩。通过对英国NES项目中的'最佳实践'案例进行深度调查和分析,结果显示:与NES参与者不同,大学生创业教育主要存在以下四个问题:最初的商业创意培养模式效果不佳;营销和会计课程实践机会少;关系网络构建效果不明显;本科生创业动力、动机和参与度欠缺。尽管政治、文化和社会环境的不同可能会导致在不同国家移植'现成的'创业课程效果有所偏差,但培养学生的创业热情、引导积极的创业文化是两个有效的措施。这一研究结果,对于我国推进大学生创新创业教育具有很好的启发作用。 周劲波 古翠凤 汤潇 2018大学教育科学2018,0,5:3
11Pandemic 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 2021Chinese Medical Journal2021,,2:3

14LINEAR AND HYPERBRANCHED POLYMERS WITH HIGH THERMAL STABILITY AND LUMINESCENCE EFFICIENCY显示文摘New acetylene monomers, 6-{[(1-naphthylethynyl-4-phenyl)carbonyl]oxy}-l-phenyl-l-hexyne (1), 2,5-diethynylthiophene (3), and 4,4′-diethynylbiphenyl (6) were synthesized. Homopolymerization of 1 and copolycyclotrimerizations of 3and 6 with 1-heptyne and l-octyne have been achieved with WCI6- and TaC15-Ph4Sn catalysts, respectively, giving soluble linear disubstituted polyacetylene (2) and hyperbranched polyarylenes (5 and 8) with high molecular weights (up to 1.2 ×105) in high yields (upto 98%). The structures and properties of the polymers are characterized and evaluated by IR, NMR,TGA, UV, photoluminescence (PL), and electroluminescence (EL) analyses. All the polymers possess high thermal stability and emit strong blue light upon photoexcitation. The intensity of the emitted light is greater than that of poly(1-phenyl-1-octyne), a well-known highly luminescent disubstituted polyacetylene. Little aggregation-induced red shift in the PL was observed in the thin films of the polymers. By constructing a multi-layer EL device, high EL quantum yield (0.18%) has been achieved in 2, which are the best results for substituted polyacetylenes attainable so far.Jacky Wing Yip Lam Jing-dong Luo Han Peng Zhi-liang Xie Kai-tian Xue Yu-ping Dong Lin Cheng Cheng-feng Qiu Hoi Sing Kwok Ben-zhong Tang Departments of Chemistry and Electrical & Electronic Engineering Hong Kong University of Science & Technology Clear Water Bay, Kowloon, Hong Kong China 2001Chinese Journal of Polymer Science2001,19,6:2
15Early-onset primary torsional dystonia in a 4-generation Chinese family with a mutation in the DYT1 gene显示文摘Primary torsion dystonia (PTD) is a clinically and genetically heterogeneous movement disorder. At least thirteen different types of dystonia can be distinguished on a genetic basis.1 The DYT1 gene was first mapped by Ozelius et al in 1989.2 (Kramer et) al3 linked the same locus to PTD in 12 Ashkenazi Jewish families in 1990. Most patients with early-onset generalized PTD were caused by the same three base pair (GAG) deletion in the DYT1 gene on chromosome 9q34.1,4,5 The product of the gene is a protein called torsinA.5 (Although the) function of this protein is as yet uncertain, it is widely distributed throughout the brain with high levels in the substantia nigra compacta dopamine neurones.YEUNG Wai Lan LAM Ching Wan CHENG Wai Tsoi SIN Ngai Chuen WONG Wing Kin WONG Chun Nei TSE Ka Ming FOK Tai Fai 2005Chinese Medical Journal2005,,10:2
16Examining patterns of traditional chinese medicine use in pediatric oncology: A systematic review, meta-analysis and data-mining study显示文摘Background Traditional Chinese medicine(TCM)is becoming a popular complementary approach in pediatric oncology.However,few or no meta-analyses have focused on clinical studies of the use of TCM in pediatric oncology.Objective We explored the patterns of TCM use and its efficacy in children with cancer,using a systematic review,meta-analysis and data mining study.Search strategy We conducted a search of five English(Allied and Complementary Medicine Database,Embase,PubMed,Cochrane Central Register of Controlled Trials,and ClinicalTrials.gov)and four Chinese databases(Wanfang Data,China National Knowledge Infrastructure,Chinese Biomedical Literature Database,and VIP Chinese Science and Technology Periodicals Database)for clinical studies published before October 2021,using keywords related to“pediatric,”“cancer,”and“TCM.”Inclusion criteria We included studies which were randomized controlled trials(RCTs)or observational clinical studies,focused on patients aged<19 years old who had been diagnosed with cancer,and included at least one group of subjects receiving TCM treatment.Data extraction and analysis The methodological quality of RCTs and observational studies was assessed using the six-item Jadad scale and the Effective Public Healthcare Panacea Project Quality Assessment Tool,respectively.Meta-analysis was used to evaluate the efficacy of combining TCM with chemotherapy.Study outcomes included the treatment response rate and occurrence of cancer-related symptoms.Association rule mining(ARM)was used to investigate the associations among medicinal herbs and patient symptoms.Results The fifty-four studies included in this analysis were comprised of RCTs(63.0%)and observational studies(37.0%).Most RCTs focused on hematological malignancies(41.2%).The study outcomes included chemotherapy-induced toxicities(76.5%),infection rate(35.3%),and response,survival or relapse rate(23.5%).The methodological quality of most of the RCTs(82.4%)and observational studies(80.0%)was rated as“moderate.”In studies of leukemia patients,adding TCM to conventional treatment significantly improved the clinical response rate(odds ratio[OR]=2.55;95%confidence interval[CI]=1.49-4.36),lowered infection rate(OR=0.23;95%CI=0.13-0.40),and reduced nausea and vomiting(OR=0.13;95%CI=0.08-0.23).ARM showed that Radix Astragali,the most commonly used medicinal herb(58.0%),was associated with treating myelosuppression,gastrointestinal complications,and infection.Conclusion There is growing evidence that TCM is an effective adjuvant therapy for children with cancer.We proposed a checklist to improve the quality of TCM trials in pediatric oncology.Future work will examine the use of ARM techniques on real-world data to evaluate the efficacy of medicinal herbs and drug-herb interactions in children receiving TCM as a part of integrated cancer therapy.Chun Sing Lam Li Wen Peng Lok Sum Yang Ho Wing Janessa Chou Chi-Kong Li Zhong Zuo Ho-Kee Koon Yin Ting Cheung 2022Journal of Integrative Medicine2022,20,5:2
