| 1 | From NAFLD to MAFLD:a“redefining”moment for fatty liver disease显示文摘The term non-alcoholic fatty liver disease(NAFLD)was coined in 1980 to characterize a disease similar to alcoholic fatty liver disease that developed in patients without a history of excessive alcohol intake.[1]Morphologically,NAFLD is characterized by excess fatty infiltration of the liver in the absence of known causes of liver disease(eg,alcohol,autoimmune liver disease,viral hepatitis,etc).The clinical manifestations of NAFLD(both hepatic and extrahepatic)depend on the outcome of complex interactions between its primary drivers including poor lifestyle habits and diet,a dysfunctional microbiota,genetic predisposition,and environmental cues that result in metabolic dysfunction and liver disease.However,bringing all patients with their markedly different clinical courses under the NAFLD umbrella belies its complexity and implies a homogeneous disease state that then negatively impacts clinical management and a deeper understanding of pathogenesis.With advances in current knowledge on the spectrum of fatty liver diseases,it is apparent that the fourdecade-old outdated term NAFLD can no longer serve to usefully describe a highly heterogeneous disease.The disease as we understand it today not only impacts patients who consume alcohol and those who do not,but also potentially impacts all patients with any form of liver disease,by acting as a disease modifier.[2] | Kenneth IZheng Jian-Gao Fan Jun-Ping Shi Vincent Wai-Sun Wong Mohammed Eslam Jacob George Ming-Hua Zheng | 2020 | Chinese Medical Journal2020，，19： | 14 |
| 2 | Strategies to increase the resectability of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is best treated by liver transplantation, but the applicability of transplantation is greatly limited. Tumor resection in partial hepatectomy is hence resorted to. However, in most parts of the world, only 20%-30% of HCCs are resectable. The main reason for such a low resectability is a future liver remnant too small to be sufficient for the patient. To allow more HCC patients to undergo curative hepatectomy, a variety of ways have been developed to increase the resectability of HCC, mainly ways to increase the future liver remnants in patients through hypertrophy. They include portal vein embolization, sequential transarterial chemoembolization and portal vein embolization, staged hepatectomy, two-staged hepatectomy with portal vein ligation, and Associating Liver Partition and Portal Vein Ligation in Staged Hepatectomy. Herein we review, describe and evaluate these different ways, ways that can be life-saving. | Wong Hoi She Kenneth SH Chok | 2015 | World Journal of Hepatology2015，7，18： | 9 |
| 3 | 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 |

| 5 | Acute pancreatitis induced by transarterial chemoembolization:a single-center experience of over 1500 cases显示文摘BACKGROUND: Acute pancreatitis is a relatively rare but potentially lethal complication after transarterial chemotherapy. This study aimed to review the complications such as acute pancreatitis after transarterial chemotherapy with or without embolization for hepatocellular carcinoma.METHODS: A total of 1632 patients with hepatocellular carcinoma who had undergone transarterial chemoembolization from January 2000 to February 2014 in a single-center were reviewed retrospectively. We investigated the potential complications of transarterial chemoembolization, such as acute pancreatitis and acute pancreatitis-related complications.RESULTS: Of the 1632 patients with hepatocellular carcinoma who had undergone 5434 transarterial chemoembolizations, 1328 were male and 304 female. The median age of these patients was 61 years. Most(79.6%) of the patients suffered from HBV-related hepatocellular carcinoma. The median tumor size was 5.2 cm. Of the 1632 patients, 145 patients underwent transarterial chemoembolization with doxorubicin eluting bead, making up a total of 538 episodes. The remaining patients underwent transarterial chemoembolization with cisplatin. Seven(0.4%) patients suffered from acute pancreatitis postchemoembolization. Six patients had chemoembolization with doxorubicin and one had chemoembolization with cisplatin. Patients who received doxorubicin eluting bead had a higher risk of acute pancreatitis [6/145(4.1%) vs 1/1487(0.1%), P<0.0001]. Two patients had anatomical arte-rial variations. Four patients developed acute pancreatitisrelated complications including necrotizing pancreatitis(n=3) and pseudocyst formation(n=1). All of the 4 patients resolved after the use of antibiotics and other conservative treatment. Three patients had further transarterial chemoembolization without any complication.CONCLUSIONS: Acute pancreatitis after transarterial chemoembolization could result in serious complications, especially after treatment with doxorubicin eluting bead. Continuation of current treatment with transarterial chemoembolization after acute pancreatitis is feasible providing the initial attack is completely resolved. | Wong Hoi She Albert CY Chan Tan To Cheung Kenneth SH Chok See Ching Chan Ronnie TP Poon Chung Mau Lo | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，1： | 6 |

| 7 | Outcomes of right-lobe and left-lobe living-donor liver transplantations using small-for-size grafts显示文摘AIM To analyze the outcomes of living-donor liver transplantation(LDLT) using left-lobe(LL) or right-lobe(RL) small-for-size(SFS) grafts.METHODS Prospectively collected data of adult patients who underwent LDLT at our hospital in the period from January 2003 to December 2013 were reviewed. The patients were divided into the RL-LDLT group and the LL-LDLT group. The two groups were compared in terms of short-and long-term outcomes, including incidence of postoperative complication, graft function, graft survival, and patient survival. A SFS graft was defined as a graft with a ratio of graft weight(GW) to recipient standard liver volume(RSLV)(GW/RSLV) of < 50%. The Urata formula was used to estimate RSLV.RESULTS Totally 218 patients were included for analysis, with 199 patients in the RL-LDLT group and 19 patients in the LL-LDLT group. The two groups were similar in terms of age(median, 53 years in the RL-LDLT group and 52 years in the LL-LDLT group, P = 0.997) but had significantly different ratios of men to women(165:34 in the RL-LDLT group and 8:11 in the LL-LDLT group, P < 0.0001). The two groups were also significantly different in GW(P < 0.0001), GW/RSLV(P < 0.0001), and graft cold ischemic time(P = 0.007). When it comes to postoperative complication, the groups were comparable(P = 0.105). Five patients died in hospital,4(2%) in the RL-LDLT group and 1(5.3%) in the LLLDLT group(P = 0.918). There were 38 graft losses, 33(16.6%) in the RL-LDLT group and 5(26.3%) in the LL-LDLT group(P = 0.452). The 5-year graft survival rate was significantly better in the RL-LDLT group(95.2% vs 89.5%, P = 0.049). The two groups had similar 5-year patient survival rates(RL-LDLT: 86.8%, LL-LDLT: 89.5%, P = 0.476).CONCLUSION The use of SFS graft in LDLT requires careful tailormade surgical planning and meticulous operation. LLLDLT can be a good alternative to RL-LDLT with similar recipient outcomes but a lower donor risk. Further research into different patient conditions is needed in order to validate the use of LL graft. | Wong Hoi She Kenneth SH Chok James YY Fung Albert CY Chan Chung Mau Lo | 2017 | World Journal of Gastroenterology2017，23，23： | 4 |
| 8 | Clinical factors affecting rejection rates in liver transplantation显示文摘BACKGROUND: With improvements in survival, liver transplant recipients now suffer more morbidity from long-term immunosuppression. Considerations were given to develop individualized immunosuppression based on their risk of rejection. METHOD: We retrospectively analyzed the data of 788 liver transplants performed during the period from October 1991 to December 2011 to study the relationship between acute cellular rejection(ACR) and various clinical factors. RESULTS: Multivariate analysis showed that older age(P=0.04,OR=0.982), chronic hepatitis B virus infection(P=0.005, OR=0.574), living donor liver transplantation(P=0.02, OR=0.648) and use of interleukin-2 receptor antagonist on induction(P<0.001, OR=0.401) were associated with fewer ACRs. Patients with fulminant liver failure(P=0.004, OR=4.05) were more likely to develop moderate to severe grade ACR. CONCLUSIONS: Liver transplant recipients with older age,chronic hepatitis B virus infection, living donor liver transplantation and use of interleukin-2 receptor antagonist on induction have fewer ACR. Patients transplanted for fulminant liver failure are at higher risk of moderate to severe grade ACR.These results provide theoretical framework for developing individualized immunosuppression. | Kin Pan Au See-Ching Chan Kenneth Siu-Ho Chok William Wei Sharr Wing-Chiu Dai Sui-Ling Sin Tiffany Cho-Lam Wong Chung-Mau Lo | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，4： | 3 |
| 9 | Engineered polycaprolactone–magnesium hybrid biodegradable porous scaffold for bone tissue engineering显示文摘In this paper, we describe the fabrication of a new biodegradable porous scaffold composed of polycaprolactone(PCL) and magnesium(Mg)micro-particles. The compressive modulus of PCL porous scaffold was increased to at least 150% by incorporating 29% Mg particles with the porosity of 74% using Micro-CT analysis. Surprisingly, the compressive modulus of this scaffold was further increased to at least 236% when the silane-coupled Mg particles were added. In terms of cell viability, the scaffold modified with Mg particles significantly convinced the attachment and growth of osteoblasts as compared with the pure PCL scaffold. In addition, the hybrid scaffold was able to attract the formation of apatite layer over its surface after 7 days of immersion in normal culture medium, whereas it was not observed on the pure PCL scaffold. This in vitro result indicated the enhanced bioactivity of the modified scaffold. Moreover, enhanced bone forming ability was also observed in the rat model after 3 months of implantation. Though bony in-growth was found in all the implanted scaffolds. High volume of new bone formation could be found in the Mg/PCL hybrid scaffolds when compared to the pure PCL scaffold. Both pure PCL and Mg/PCL hybrid scaffolds were degraded after 3 months. However, no tissue inflammation was observed. In conclusion, these promising results suggested that the incorporation of Mg micro-particles into PCL porous scaffold could significantly enhance its mechanical and biological properties. This modified porous bio-scaffold may potentially apply in the surgical management of large bone defect fixation. | Hoi Man Wong Paul K.Chu Frankie K.L.Leung Kenneth M.C.Cheung Keith D.K.Luk Kelvin W.K.Yeung | 2014 | Progress in Natural Science:Materials International2014，24，5： | 3 |
| 10 | 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 |
| 11 | Role of C11-FDG dual-tracer PET-CT scan in metastatic screening of hepatocellular carcinoma-a cost-effectiveness analysis显示文摘Background:We aimed to identify predictive factors for positron emission tomography(PET)-detected hepatocellular carcinoma(HCC)metastasis and a cost-effective approach to preoperative PET-computed tomography(CT)for detecting metastasis.Methods:Clinicopathological and survival data of HCC patients having PET-CT with 18F-fludeoxyglucose(FDG)and 11C-acetate(ACT)following contrast-enhanced CT/magnetic resonance imaging(MRI)for preoperative tumor staging were reviewed.Binary logistic regression was performed to identify predictive factors for PET-detected metastasis.A cost-benefit analysis model was built for the incurred costs and the impact of PET-CT findings on treatment strategy was studied.Results:Totally 152 patients were analyzed.Dual-tracer PET-CT detected metastasis in 17 patients(11%).By multivariate analysis,alpha-fetoprotein(AFP)≥400 ng/mL[relative risk(RR):4.30,95%confidence interval(CI):1.41-13.15,P=0.011]and bilobar disease(RR:3.94,95%CI:1.24-12.52,P=0.014)were independent predictive factors for PET-detected metastasis.PET-CT findings altered the treatment strategy for 12 patients(7.9%);three partial hepatectomies,eight episodes of transarterial chemoembolization(TACE)and one episode of ablation were avoided,with an estimated cost-saving of US$91,000,$150,000 and$10,600 respectively.Had the PET-CT been performed only for patients with AFP≥400 ng/mL or bilobar disease(n=74),metastasis would have been confirmed in 14 patients(18.9%),and the cost-saving per patient was estimated at US$1,070.Conclusions:Dual-tracer PET-CT is cost-effective and useful for preoperative HCC staging in patients with AFP≥400 ng/mL or bilobar disease.Its routine use in preoperative workup for all HCC patients is not recommended.Unilobar disease with AFP<400 ng/mL can achieve good negative predictive value for PET-detected metastasis.Screening patients with either factor can avoid unnecessary procedures and is thus cost-effective for preoperative HCC workup. | Kevin K.W.Chu Albert C.Y.Chan Ka Wing Ma Wong Hoi She Wing Chiu Dai Kenneth S.H.Chok Tan To Cheung Chung Mau Lo | 2021 | Hepatobiliary Surgery and Nutrition2021，10，3： | 2 |
| 12 | 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 |
| 13 | Fiber optical parametric oscillator based on highly nonlinear dispersion-shifted fiber显示文摘The development of fiber optical parametric oscillators (FOPO) based on highly nonlinear dispersion- shifted fiber is reviewed in this paper. Firstly, the background and motivation are introduced, and it is pointed out that the FOPO is promising to act as optical source in non-conventional wavelength bands. Subsequently, the context focuses principally on the problem of inherent multiple-longitudinal-mode characteristic of FOPO and the corresponding solutions to it. The primary technique is by locking the phase of multiple longitudinal modes. The first reported actively mode locked FOPO is also presented in this article. However, it is not probable to realize passively mode locked FOPO because of the random phase dithering of the pump required for suppressing stimulated Brillouin scattering. Furthermore, a regeneratively mode locked FOPO is demonstrated, which can generate wide band tunable radiation in non- conventional wavelengths. Besides mode locked FOPO, the single-longitudinal-mode FOPO is also introduced. Finally, potential future directions are discussed. | Sigang YANG Kenneth K. Y.

| 16 | 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 |
