| 1 | Are newborn rat-derived neural stem cells more sensitive to lead neurotoxicity?显示文摘Lead ion (Pb(2+) ) has been proven to be a neurotoxin due to its neurotoxicity on mammalian nervous system, especially for the developing brains of juveniles. However, many reported studies involved the negative effects of Pb(2+) on adult neural cells of humans or other mammals, only few of which have examined the effects of Pb(2+) on neural stem cells. The purpose of this study was to reveal the biological effects of Pb(2+) from lead acetate [Pb (CH 3 COO) 2 ] on viability, proliferation and differentiation of neural stem cells derived from the hippocampus of newborn rats aged 7 days and adult rats aged 90 days, respectively. This study was carried out in three parts. In the first part, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (MTT viability assay) was used to detect the effects of Pb(2+) on the cell viability of passage 2 hippocampal neural stem cells after 48-hour exposure to 0-200 μM Pb(2+) . In the second part, 10 μM bromodeoxyuridine was added into the culture medium of passage 2 hippocampal neural stem cells after 48-hour exposure to 0- 200 μM Pb(2+) , followed by immunocytochemical staining with anti-bromodeoxyuridine to demonstrate the effects of Pb(2+) on cell proliferation. In the last part, passage 2 hippocampal neural stem cells were allowed to grow in the differentiation medium with 0-200 μM Pb(2+) . Immunocytochemical staining with anti-microtubule-associated protein 2 (a neuron marker), anti-glial fibrillary acidic protein (an astrocyte marker), and anti-RIP (an oligodendrocyte marker) was performed to detect the differentiation commitment of affected neural stem cells after 6 days. The data showed that Pb(2+) inhibited not only the viability and proliferation of rat hippocampal neural stem cells, but also their neuronal and oligodendrocyte differentiation in vitro. Moreover, increased activity of astrocyte differentiation of hippocampal neural stem cells from both newborn and adult rats was observed after exposure to high concentration of lead ion in vitro. These findings suggest that hippocampal neural stem cells of newborn rats were more sensitive than those from adult rats to Pb(2+) cytotoxicity. | Yan Ho Chan Mingyong Gao Wutian Wu | 2013 | Neural Regeneration Research2013，8，7： | 14 |
| 2 | Survival outcomes of liver transplantation for hepatocellular carcinoma in patients with normal, high and very high preoperative alpha-fetoprotein levels显示文摘AIM To investigate the impact of alpha-fetoprotein(AFP) on long-term recurrence rate and overall survival and we also aimed to define the level of AFP leading to a higher risk of disease recurrence and affecting patient survival.METHODS Data of adult patients who received liver transplant(LT) for hepatocellular carcinoma(HCC) at our hospital from January 2000 to December 2013 were reviewed. Reviewed data included demographic characteristics, preoperative AFP level, operative details, follow-up details, and survival outcomes. Patients were mostly listed for LT based on Milan or UCSF criteria. For the purpose of this study, normal AFP level was defined as AFP value < 10 ng/m L, high AFP level was defined as AFP value ≥ 10 to < 400 ng/m L, and very highAFP level was defined as AFP ≥ 400 ng/m L. The patients were divided into these 3 groups accordingly. Survival rates were plotted as Kaplan-Meier curves and compared by log-rank analysis. Continuous variables were expressed as median(interquartile range). Categorical variables were compared by Spearman's test. Discriminative analysis was used to define the lowest value of AFP that could affect the overall survival in study population. Statistical significance was defined by a P value of < 0.05.RESULTS Totally 250 adult patients underwent LT for HCC in the study period. Eight-four of them received deceaseddonor LT and 166 had living-donor LT. The patients were divided into 3 groups: Group A, AFP < 10 ng/m L(n = 83); Group B, AFP ≥ 10 to < 400 ng/m L(n = 131); Group C, AFP ≥ 400 ng/m L(n = 36). The commonest etiology was hepatitis-B-related cirrhosis. The Model for End-stage Liver Disease scores in these groups were similar(median, 13 vs 13 vs 12; P = 0.745). The time to operation in Group A was longer(median, 94 vs 31 vs 35 d; P = 0.001). The groups were similar in hospital mortality(P = 0.626) and postoperative complication(P = 0.702). Pathology of explants showed that the 3 groups had similar numbers of tumor nodules, but the tumors in Group C were larger(A: 2.5 cm, B: 3.0 cm, C: 4.0 cm; P = 0.003). Group C had a bigger proportion of patients who were beyond Milan criteria(P = 0.010). Poor differentiation and vascular permeation were also more common in this group(P = 0.017 and P = 0.003 respectively). It also had poorer 5-year survival(A: 85.5%, B: 82.4%, C: 66%; P = 0.029). The 5-year disease-free survival was 84.3% in Group A, 80.1% in Group B, and 61.1% in Group C. Receiver operating characteristic area under the curve for AFP in predicting tumor recurrence was 0.685. The selected cut-off value was 54 ng/m L for AFP(C-index 0.685; 95%CI: 0.592-0.779; sensitivity 0.595; specificity 0.687). On discriminative analysis, AFP value of 105 ng/m L was shown to affect the overall survival of the patients.CONCLUSION HCC patients with a high preoperative AFP level had inferior survival after LT. AFP level of 54 ng/m L was associated with disease recurrence, and AFP level of 105 ng/m L was found to be the cut-off value for overall survival difference. | Wong Hoi She Albert Chi Yan Chan Tan To Cheung Chung Mau Lo Kenneth Siu Ho Chok | 2018 | World Journal of Hepatology2018，10，2： | 7 |
| 3 | A cross-sectional study on compliance with topical glaucoma medication and its associated socioeconomic burden for a Chinese population显示文摘AIM: To estimate the overall drug compliance for local Chinese glaucoma patients on long-term topical treatment.METHODS: This was a retrospective cross-sectional study.Fifty-seven primary glaucoma patients from the subspecialty clinic of a publicly-funded tertiary care hospital in Hong Kong completed a questionnaire on compliance with topical glaucoma medication,attitude towards glaucoma and therapy and vision related quality of life.Noncompliance was defined as reporting missing more than or equal to 10% of the prescribed topical glaucoma medication during the 2wk immediately prior to the consultation.Relationships between noncompliance and demographics,attitude,disease and treatment status was studied.Cost was estimated with quality of life and direct medical cost involved with noncompliance.Multivariable logistic regression on noncompliance was performed on selected factors.RESULTS: Compliance was calculated as 75%(95% CI: 64%-87%) among 57 subjects(mean age 69 y,female 51%).No statistical significant relationship was established between noncompliance and any single factors or outcomes.Age(P=0.048) and forgetfulness(P=0.064) were found to be marginally significant predictive factors on noncompliance in multivariable logistic regression.Noncompliance might be related(P=0.130) to poorer self-rated vision-associated quality of life.The societal cost of noncompliance was estimated to be over 2510 life-years and US$ 3.7 million territory-wide.CONCLUSION: The compliance of Chinese glaucoma patients in Hong Kong is comparable to other parts in the world,and carries detrimental impacts on individual and societal levels.Age and forgetfulness are two possible independent predictors for noncompliance. | Man-Hin Lui Jason Chun Ho Lam Yi Lee Kwong Tak Siu Wong Pak Long Cheung Sherri Shun Yan Lai Pak Lun Yuen Wai Yiu Lam Ho Yan Chan Yiu Fai Wong Jimmy Shiu Ming Lai Kendrick Co Shih | 2017 | International Journal of Ophthalmology(English edition)2017，10，2： | 5 |
| 4 | Initial experience with stereotactic body radiotherapy for intrahepatic hepatocellular carcinoma recurrence after liver transplantation显示文摘BACKGROUND Graft hepatocellular carcinoma(HCC)recurrence after liver transplant is more frequently encountered.Graft hepatectomy is technically challenging and is associated with high morbidity.Stereotactic body radiation therapy(SBRT)has been shown to be safe and effective for the treatment of primary HCC.However,its role in HCC recurrence in a liver graft remains unclear.AIM To evaluate the safety and efficacy of SBRT for the treatment of graft HCC recurrence after liver transplantation.METHODS A retrospective study was conducted.From 2012 to 2018,6 patients with intrahepatic HCC recurrence after liver transplant were treated with SBRT at Queen Mary Hospital,the University of Hong Kong.The primary outcome was time to overall disease progression and secondary outcomes were time to local progression and best local response,as assessed with the Modified response Evaluation Criteria for Solid Tumours criteria.Patients were monitored for treatment related toxicities and graft dysfunction.RESULTS A total of 9 treatment courses were given for 13 tumours.The median tumour size was 2.3 cm(range 0.7-3.6 cm).Two(22%)patients had inferior vena cava tumour thrombus.The best local treatment response was:5(55%)complete response,1(11%)partial response and 3(33%)stable disease.After a median follow up duration of 15.5 mo,no local progression or mortality was yet observed.The median time to overall disease progression was 6.5 mo.There were 6 regional progression in the liver graft(67%)and 2 distant progression in the lung(22%).There was no grade 3 or above toxicity and there was no graft dysfunction after SBRT.CONCLUSION SBRT appears to be safe in this context.Regional progression is the mode of failure. | Kin Pan Au Chi Leung Chiang Albert Chi Yan Chan Tan To Cheung Chung Mau Lo Kenneth Siu Ho Chok | 2020 | World Journal of Clinical Cases2020，8，13： | 3 |
| 5 | Intravenous 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 | 2018 | World Journal of Emergency Medicine2018，9，1： | 3 |
| 6 | Impact 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 | 2019 | World Journal of Gastroenterology2019，25，36： | 3 |

| 8 | Liver 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 | 2021 | Hepatobiliary Surgery and Nutrition2021，10，3： | 2 |

| 10 | Validated 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 | 2019 | World Journal of Gastrointestinal Oncology2019，11，4： | 2 |

| 16 | Deep learning based radiomics for gastrointestinal cancer diagnosis and treatment:A minireview显示文摘Gastrointestinal(GI)cancers are the major cause of cancer-related mortality globally.Medical imaging is an important auxiliary means for the diagnosis,assessment and prognostic prediction of GI cancers.Radiomics is an emerging and effective technology to decipher the encoded information within medical images,and traditional machine learning is the most commonly used tool.Recent advances in deep learning technology have further promoted the development of radiomics.In the field of GI cancer,although there are several surveys on radiomics,there is no specific review on the application of deep-learning-based radiomics(DLR).In this review,a search was conducted on Web of Science,PubMed,and Google Scholar with an emphasis on the application of DLR for GI cancers,including esophageal,gastric,liver,pancreatic,and colorectal cancers.Besides,the challenges and recommendations based on the findings of the review are comprehensively analyzed to advance DLR. | Pak Kin Wong In Neng Chan Hao-Ming Yan Shan Gao Chi Hong Wong Tao Yan Liang Yao Ying Hu Zhong-Ren Wang Hon Ho Yu | 2022 | World Journal of Gastroenterology2022，28，45： | 1 |
| 17 | A machine learning model for colorectal liver metastasis post-hepatectomy prognostications显示文摘Background:Currently,surgical resection is the mainstay for colorectal liver metastases(CRLM)management and the only potentially curative treatment modality.Prognostication tools can support patient selection for surgical resection to maximize therapeutic benefit.This study aimed to develop a survival prediction model using machine learning based on a multicenter patient sample in Hong Kong.Methods:Patients who underwent hepatectomy for CRLM between 1 January 2009 and 31 December 2018 in four hospitals in Hong Kong were included in the study.Survival analysis was performed using Cox proportional hazards(CPH).A stepwise selection on Cox multivariable models with Least Absolute Shrinkage and Selection Operator(LASSO)regression was applied to a multiply-imputed dataset to build a prediction model.The model was validated in the validation set,and its performance was compared with that of Fong Clinical Risk Score(CRS)using concordance index.Results:A total of 572 patients were included with a median follow-up of 3.6 years.The full models for overall survival(OS)and recurrence-free survival(RFS)consist of the same 8 established and novel variables,namely colorectal cancer nodal stage,CRLM neoadjuvant treatment,Charlson Comorbidity Score,pre-hepatectomy bilirubin and carcinoembryonic antigen(CEA)levels,CRLM largest tumor diameter,extrahepatic metastasis detected on positron emission-tomography(PET)-scan as well as KRAS status.Our CRLM Machine-learning Algorithm Prognostication model(CMAP)demonstrated better ability to predict OS(C-index=0.651),compared with the Fong CRS for 1-year(C-index=0.571)and 5-year OS(C-index=0.574).It also achieved a C-index of 0.651 for RFS.Conclusions:We present a promising machine learning algorithm to individualize prognostications for patients following resection of CRLM with good discriminative ability. | Cynthia Sin Nga Lam Alina Ashok Bharwani Evelyn Hui Yi Chan Vernice Hui Yan Chan Howard Lai Ho Au Margaret Kay Ho Shireen Rashed Bernard Ming Hong Kwong Wentao Fang Ka Wing Ma Chung Mau Lo Tan To Cheung | 2023 | Hepatobiliary Surgery and Nutrition2023，12，4： | 0 |

| 19 | Genomics-driven derivatization of the bioactive fungal sesterterpenoid variecolin:Creation of an unnatural analogue with improved anticancer properties显示文摘A biosynthetic gene cluster for the bioactive fungal sesterterpenoids variecolin(1)and variecolactone(2)was identified in Aspergillus aculeatus ATCC 16872.Heterologous production of 1 and 2 was achieved in Aspergillus oryzae by expressing the sesterterpene synthase VrcA and the cytochrome P450 VrcB.Intriguingly,the replacement of VrcB with homologous P450s from other fungal terpenoid pathways yielded three new variecolin analogues(5-7).Analysis of the compounds’anticancer activity in vitro and in vivo revealed that although 5 and 1 had comparable activities,5 was associated with significantly reduced toxic side effects in cancer-bearing mice,indicating its potentially broader therapeutic window.Our study describes the first tests of variecolin and its analogues in animals and demonstrates the utility of synthetic biology for creating molecules with improved biological activities. | Dexiu Yan Jemma Arakelyan Teng Wan Ritvik Raina Tsz Ki Chan Dohyun Ahn Vladimir Kushnarev Tsz Kiu Cheung Ho Ching Chan Inseo Choi Pui Yi Ho Feijun Hu Yujeong Kim Hill Lam Lau Ying Lo Law Chi Seng Leung Chun Yin Tong Kai Kap Wong Wing Lam Yim Nikolay S.Karnaukhov Richard Y.C.Kong Maria V.Babak Yudai Matsuda | 2024 | Acta Pharmaceutica Sinica B2024，14，1： | 0 |
| 20 | Multinational survey on the preferred approach to management of Barrett’s esophagus in the Asia-Pacific region显示文摘BACKGROUND Major societies provide differing guidance on management of Barrett’s esophagus(BE),making standardization challenging.AIM To evaluate the preferred diagnosis and management practices of BE among Asian endoscopists.METHODS Endoscopists from across Asia were invited to participate in an online questionnaire comprising eleven questions regarding diagnosis,surveillance and management of BE.RESULTS Five hundred sixty-nine of 1016(56.0%)respondents completed the survey,with most respondents from Japan(n=310,54.5%)and China(n=129,22.7%).Overall,the preferred endoscopic landmark of the esophagogastric junction was squamocolumnar junction(42.0%).Distal palisade vessels was preferred in Japan(59.0%vs 10.0%,P<0.001)while outside Japan,squamo-columnar junction was preferred(59.5%vs 27.4%,P<0.001).Only 16.3%of respondents used Prague C and M criteria all the time.It was never used by 46.1%of Japanese,whereas 84.2%outside Japan,endoscopists used it to varying extents(P<0.001).Most Asian endoscopists(70.8%)would survey long-segment BE without dysplasia every two years.Adherence to Seattle protocol was poor with only 6.3%always performing it.73.2%of Japanese never did it,compared to 19.3%outside Japan(P<0.001).The most preferred(74.0%)treatment of non-dysplastic BE was proton pump inhibitor only when the patient was symptomatic or had esophagitis.For BE with low-grade dysplasia,6-monthly surveillance was preferred in 61.9%within Japan vs 47.9%outside Japan(P<0.001).CONCLUSION Diagnosis and management of BE varied within Asia,with stark contrast between Japan and outside Japan.Most Asian endoscopists chose squamo-columnar junction to be the landmark for esophagogastric junction,which is incorrect.Most also did not consistently use Prague criteria,and Seattle protocol.Lack of standardization,education and research are possible reasons. | Guan Sen Kew Alex Yu Sen Soh Yeong Yeh Lee Takuji Gotoda Yan-Qing Li Yan Zhang Yiong Huak Chan Kewin Tien Ho Siah Daniel Tong Simon Ying Kit Law Andrew Ruszkiewicz Ping-Huei Tseng Yi-Chia Lee Chi-Yang Chang Duc Trong Quach Chika Kusano Shobna Bhatia Justin Che-Yuen Wu Rajvinder Singh Prateek Sharma Khek-Yu Ho | 2021 | World Journal of Gastrointestinal Oncology2021，13，4： | 0 |
