2First observation of tropospheric nitrogen dioxide from the Environmental Trace Gases Monitoring Instrument onboard the GaoFen-5 satellite显示文摘The Environmental Trace Gases Monitoring Instrument(EMI)is the first Chinese satellite-borne UV–Vis spectrometer aiming to measure the distribution of atmospheric trace gases on a global scale.The EMI instrument onboard the GaoFen-5 satellite was launched on 9 May 2018.In this paper,we present the tropospheric nitrogen dioxide(NO2)vertical column density(VCD)retrieval algorithm dedicated to EMI measurement.We report the first successful retrieval of tropospheric NO_(2) VCD from the EMI instrument.Our retrieval improved the original EMI NO_(2) prototype algorithm by modifying the settings of the spectral fit and air mass factor calculations to account for the on-orbit instrumental performance changes.The retrieved EMI NO_(2) VCDs generally show good spatiotemporal agreement with the satellite-borne Ozone Monitoring Instrument and TROPOspheric Monitoring Instrument(correlation coefficient R of ~0.9,bias<50%).A comparison with ground-based MAX-DOAS(Multi-Axis Differential Optical Absorption Spectroscopy)observations also shows good correlation with an R of 0.82.The results indicate that the EMI NO_(2) retrieval algorithm derives reliable and precise results,and this algorithm can feasibly produce stable operational products that can contribute to global air pollution monitoring.Chengxin Zhang Cheng Liu Ka Lok Chan Qihou Hu Haoran Liu Bo Li Chengzhi Xing Wei Tan Haijin Zhou Fuqi Si Jianguo Liu 2020Light(Science & Applications)2020,9,1:11

4Profiles 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

6Cell cycle-related kinase reprograms the liver immune microenvironment to promote cancer metastasis显示文摘The liver is an immunologically tolerant organ and a common metastatic site of multiple cancer types.Although a role for cancer cell invasion programs has been well characterized,whether and how liver-intrinsic factors drive metastatic spread is incompletely understood.Here,we show that aberrantly activated hepatocyte-intrinsic cell cycle-related kinase(CCRK)signaling in chronic liver diseases is critical for cancer metastasis by reprogramming an immunosuppressive microenvironment.Using an inducible liverspecific transgenic model,we found that CCRK overexpression dramatically increased both B16F10 melanoma and MC38 colorectal cancer(CRC)metastasis to the liver,which was highly infiltrated by polymorphonuclear-myeloid-derived suppressor cells(PMNMDSCs)and lacking natural killer T(NKT)cells.Depletion of PMN-MDSCs in CCRK transgenic mice restored NKT cell levels and their interferon gamma production and reduced liver metastasis to 2.7% and 0.7%(metastatic tumor weights)in the melanoma and CRC models,respectively.Mechanistically,CCRK activated nuclear factor-kappa B(NF-κB)signaling to increase the PMN-MDSC trafficking chemokine C-X-C motif ligand 1(CXCL1),which was positively correlated with liver-infiltrating PMN-MDSC levels in CCRK transgenic mice.Accordingly,CRC liver metastasis patients exhibited hyperaaivation of hepatic CCRK/NF-κB/CXCL1 signaling,which was associated with accumulation of PMN-MDSCs and paucity of NKT cells compared to healthy liver transplantation donors.In summary,this study demonstrates that immunosuppressive reprogramming by hepatic CCRK signaling undermines antimetastatic immunosurveillance.Our findings offer new mechanistic insights and therapeutic targets for liver metastasis intervention.Xuezhen Zeng Jingying Zhou Zhewen Xiong Hanyong Sun Weiqin Yang Myth T.S.Mok Jing Wang Jingqing Li Man Liu Wenshu Tang Yu Feng Hector Kwong-Sang W ang Shun-Wa Tsang King-Lau Chow Philip Chun Yeung John Wong Paul Bo-San Lai Anthony Wing-Hung Chan Ka Fai To Stephen Lam Chan Qiang Xia Jing Xue Xiao Chen Jun Yu Sui Peng Joseph Jao-Yiu Sung Ming Kuang Alfred Sze-Lok Cheng 2021Cellular & Molecular Immunology2021,18,4:5

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
10Modified Zhibai Dihuang pill,a traditional Chinese medicine formula,on steroid withdrawal in systemic lupus erythematosus:A systematic review and meta-analysis显示文摘Background:Zhibai Dihuang pill(ZBDH),a Chinese herbal formula,has been widely used as an adjunctive therapy to help reduce the patient’s steroid dose and maintain low disease activity in systemic lupus erythematosus(SLE).Objective:This systematic review evaluates the therapeutic effect of modified ZBDH in reducing steroid use in patients with SLE.Search strategy:A systematic literature search was carried out using seven databases,including PubMed,Embase,Cochrane Central Register of Controlled Trials,Chinese Biomedical Literature Database,Chinese National Knowledge Infrastructure,Chinese VIP Information and Wanfang Database,from their inception to June 1 st,2019.The search terms included‘‘systemic lupus erythematosus,'‘‘Chinese medicine'and‘‘clinical trial,'and their synonyms.Subject headings matching the above terms were also used.Inclusion criteria:This meta-analysis included randomized controlled trials that evaluated the reduction of steroid dose in patients with SLE.Traditional Chinese medicine(TCM)formulas in experimental group should be prescribed based on ZBDH and used as adjunctive therapy and the comparator should contain steroids.Data extraction and analysis:Two authors independently conducted database search,study selection,data extraction and quality assessment.The extracted information contained study design,sample size,recruitment mode,diagnostic criteria,inclusion and exclusion criteria,participant characteristics,TCM patterns,TCM formulas and treatment outcomes.The primary outcome was the change of steroid dose.Secondary outcomes included SLE Disease Activity Index(SLEDAI),biomarkers of disease activity and clinical response rate.STATA 15.0 was used to analyze the pooled effects reported as weighted mean difference(WMD)or odds ratio,with a 95%confidence interval(CI).Results:In total,20 trials involving 1470 SLE patients were included.The pooled result showed that modified ZBDH taken in combination with standard care led to a larger reduction in steroid dose,compared to standard care alone(WMD:3.79;95%CI:2.58–5.01;P<0.001).Favorable outcomes were also seen in secondary outcome criteria,such as SLEDAI and complement 3.The modified ZBDH treatments were well tolerated without increasing adverse effects.Conclusion:The systematic review provided preliminary evidence supporting the use of ZBDH as a cotherapy to aid steroid dose reduction in patients with SLE.However,more rigorous studies should be conducted to validate these findings,and explore the mechanisms of ZBDH’s relevant bioactive constituents.Liang Dai Ka Kei Chan Jian-chun Mao Yu Tianc Jun-hua Gu Jun Zhou Linda L.D.Zhong 2020Journal of Integrative Medicine2020,18,6:3
11Impact of small-for-size liver grafts on medium-term and long-term graft survival in living donor liver transplantation: A meta-analysis显示文摘BACKGROUND Small-for-size grafts (SFSGs) in living donor liver transplantation (LDLT) could optimize donor postoperative outcomes and also expand the potential donor pool. Evidence on whether SFSGs would affect medium-term and long-term recipient graft survival is lacking. AIM To evaluate the impact of small-for-size liver grafts on medium-term and longterm graft survival in adult to adult LDLT. METHODS A systematic review and meta-analysis were performed by searching eligible studies published before January 24, 2019 on PubMed, EMBASE, and Web of Science databases. The primary outcomes were 3-year and 5-year graft survival. Incidence of small-for-size syndrome and short term mortality were also extracted. RESULTS This meta-analysis is reported according to the guidelines of the PRISMA 2009 Statement. Seven retrospective observational studies with a total of 1821 LDLT recipients were included in the meta-analysis. SFSG is associated with significantly poorer medium-term graft survival. The pooled odds ratio for 3-year graft survival was 1.58 [95% confidence interval 1.10-2.29, P = 0.014]. On the other hand, pooled results of the studies showed that SFSG had no significant discriminatory effect on 5-year graft survival with an odds ratio of 1.31 (95% confidence interval 0.87-1.97, P = 0.199). Furthermore, incidence of small-for-size syndrome detected in recipients of SFSG ranged from 0-11.4% in the included studies. CONCLUSION SFSG is associated with inferior medium-term but not long-term graft survival. Comparable long-term graft survival based on liver graft size shows that smaller grafts could be accepted for LDLT with appropriate flow modulatory measures. Close follow-up for graft function is warranted within 3 years after liver transplantation.Ka Wing Ma Kelly Hiu Ching Wong Albert Chi Yan Chan Tan To Cheung Wing Chiu Dai James Yan Yue Fung Wong Hoi She Chung Mau Lo Kenneth Siu Ho Chok 2019World Journal of Gastroenterology2019,25,36:3
12How does Covid-19 affect global equity markets?显示文摘This study applies OLS,panel regression and Granger causality test to investigate the impact of the Coronavirus disease 2019(Covid-19)outbreak on the global equity markets during the early stage of the pandemic.We find that the Covid-19 outbreak has a significant negative impact on the overall equity index return of the eight economies even at 0.1%significance level.Furthermore,the pandemic has a more significant impact on the European countries than on the East Asian economies.The results have three main implications.Firstly,policy makers should react fast to mitigate the impact of a crisis.Secondly,investors should be aware of an outbreak of disease or other risks and adjust their investments accordingly.Furthermore,the Covid-19 outbreak results in a shift of power from the west to the east.Eddie C.M.Hui Ka Kwan Kevin Chan 2022Financial Innovation2022,8,1:3
13Weather Information Acquisition and Health Significance during Extreme Cold Weather in a Subtropical City:A Crosssectional Survey in Hong Kong显示文摘Health and disaster risk reduction are important and necessary components in building a smart city,especially when climate change may increase the frequency of extreme temperatures and the health risks of urban dwellers.However,limited knowledge is available about the best way to disseminate weather warnings and health protection information.This study explores the weather information acquisition patterns of the Hong Kong public and examines the sociodemographic predictors of these patterns to establish the potential public health implications of smart city development.A population-based,stratified crosssectional,random digit dialing telephone survey was conducted among the Cantonese-speaking population aged over 15 years in Hong Kong in early 2016.Analyses were conducted based on 1017 valid samples,with a response rate of 63.6%.Cold Weather Warnings were well disseminated in Hong Kong,with 95.7% of the respondents reporting awareness of the public warnings.Television and smartphone apps were the two most important channels for weather information acquisition.Age and education level are the main social-demographic variables associated with the current utilization and future preference of smartphone technology.Among those who were not using a preferredchannel to acquire weather information,61.3% considered switching to a smartphone app.Moreover,the patterns of individual health protection measures and self-reported health impacts were significantly different between smartphone app users and non-users.Weather information dissemination should be tailored to the sociodemographic characteristics of the users.Emily Ying Yang Chan Zhe Huang Carman Ka Man Mark Chunlan Guo 2017International Journal of Disaster Risk Science2017,8,2:2
14Liver transplantation:would it be the best and last chance of cure for hepatocellular carcinoma with major venous invasion?显示文摘Background:Hepatocellular carcinoma(HCC)with portal vein tumour thrombus(PVTT)signifies advanced disease,whether LT confers any survival superiority over resection remains uncertain.Methods:A propensity score matched(PSM)analysis of liver transplantation(LT)and liver resection(LR)for HCC with PVTT was performed.Results:A consecutive series of 88 patients who received either LT(10 DDLTs and 3 LDLTs)or LR(n=75)respectively were recruited.Before PSM,the LT group has a higher MELD score(17.3 vs.7.8,P<0.001),lower serum AFP levels(96 vs.2,164 ng/mL,P=0.017)and smaller tumour size(4 vs.10 cm,P<0.001).The 5-year overall survival for LT and LR were 55.4%and 15.9%respectively(P=0.007).After matching for serum AFP levels and tumour size,1-,3-and 5-year overall survival for LT were 81 ng/mL,3.9 cm,80%,70%and 70%and the corresponding rates for LR were 1,417 ng/mL,5.3 cm,51.8%,19,6%and 9.8%(P value=0.12,0.27 and 0.009 respectively).Conclusions:LT is associated with significantly better oncological outcomes in HCC patients with PVTT involving the lobar or segmental level.A modest expansion of selection criteria to include small HCC with segmental PVTT should be considered.Ka Wing Ma Albert Chi Yan Chan Kenneth Siu Ho Chok Wong Hoi She Tan To Cheung Wing Chiu Dai James Yan Yue Fung Chung Mau Lo 2021Hepatobiliary Surgery and Nutrition2021,10,3:2

17Modelling the impact of sea-level rise on urban flood probability in SE China显示文摘Urban drainage systems in coastal cities in SE China are characterized by often complex canal and sluicegate systems that are designed to safely drain pluvial flooding whilst preventing tidal inundation.However, the risk of coastal flooding in the region is expected to increase over the next 50-100 years, as urban areas continue to expand and sea-levels are expected to rise. To assess the impact of projected sealevel rise on this type of urban drainage system, a one-dimensional model and decision support tool was developed. The model indicated that although sea-level rise represents a significant challenge, flood probability will continue to be most influenced by rainfall. Events that are significant enough to cause flooding will most likely be minimally impacted by changes to the tidal frame. However, it was found that a sea-level rise of up to 1.2 m by 2010 would result in increased drainage times and higher volumes of over-topping when flooding occurs.James Andrew Griffiths Fangfang Zhu Faith Ka Shun Chan David Laurence Higgitt 2019Geoscience Frontiers2019,10,2:2

19Validated model for prediction of recurrent hepatocellular carcinoma after liver transplantation in Asian population显示文摘BACKGROUND Liver transplantation(LT) is regarded as the best treatment for both primary and recurrent hepatocellular carcinoma(HCC). Post-transplant HCC recurrence rate is relatively low but significant, ranging from 10%-30% according to different series. When recurrence happens, it is usually extrahepatic and associated with poor prognosis. A predictive model that allows patient stratification according to recurrence risk can help to individualize post-transplant surveillance protocol and guidance of the use of anti-tumor immunosuppressive agents.AIM To develop a scoring system to predict HCC recurrence after LT in an Asian population.METHODS Consecutive patients having LT for HCC from 1995 to 2016 at our hospital were recruited. They were randomized into the training set and the validation set in a60:40 ratio. Multivariable Cox regression model was used to identity factors associated with HCC recurrence. A risk score was assigned to each factor according to the odds ratio. Accuracy of the score was assessed by the area under the receiver operating characteristic curve.RESULTS In total, 330 patients were eligible for analysis(183 in training and 147 invalidation). Recurrent HCC developed in 14.2% of them. The median follow-up duration was 65.6 mo. The 5-year disease-free and overall survival rates were78% and 80%, respectively. On multivariate analysis, alpha-fetoprotein > 400 ng/mL [P = 0.012, hazard ratio(HR) 2.92], sum of maximum tumor size and number(P = 0.013, HR 1.15), and salvage LT(P = 0.033, HR 2.08) were found to be independent factors for disease-free survival. A risk score was calculated for each patient with good discriminatory power(c-stat 0.748 and 0.85, respectively,in the training and validation sets). With the derived scores, patients were classified into low-(0–9), moderate-(> 9–14), and high-risk groups(> 14), and the risk of HCC recurrence in the training and validation sets was 10%, 20%, 54%(cstat 0.67) and 4%, 22%, 62%(c-stat 0.811), accordingly. The risk stratification model was validated with chi-squared goodness-of-fit test(P = 0.425).CONCLUSION A validated predictive model featuring alpha-fetoprotein, salvage LT, and the sum of largest tumor diameter and total number of tumor nodule provides simple and reliable guidance for individualizing postoperative surveillance strategy.Ka Wing Ma Wong Hoi She Albert Chi Yan Chan Tan To Cheung James Yan Yue Fung Wing Chiu Dai Chung Mau Lo Kenneth Siu Ho Chok 2019World Journal of Gastrointestinal Oncology2019,11,4:2
