| 1 | Robotic surgery for rectal cancer: A systematic review of current practice显示文摘AIM: To give a comprehensive review of current litera-ture on robotic rectal cancer surgery.METHODS: A systematic review of current literature via PubMed and Embase search engines was per-formed to identify relevant articles from january 2007 to november 2013. The keywords used were: 'robotic surgery', 'surgical robotics', 'laparoscopic computer-assisted surgery', 'colectomy' and 'rectal resection'. RESULTS: After the initial screen of 380 articles, 20 pa-pers were selected for review. A total of 1062 patients(male 64.0%) with a mean age of 61.1 years and body mass index of 24.9 kg/m2 were included in the review.Out of 1062 robotic-assisted operations, 831(78.2%) anterior and low anterior resections, 132(12.4%) in-tersphincteric resection with coloanal anastomosis, 98(9.3%) abdominoperineal resections and 1(0.1%) Hart-mann's operation were included in the review. Robotic rectal surgery was associated with longer operative time but with comparable oncological results and anastomotic leak rate when compared with laparoscopic rectal surgery. CONCLUSION: Robotic colorectal surgery has con-tinued to evolve to its current state with promising re-sults; feasible surgical option with low conversion rate and comparable short-term oncological results. The challenges faced with robotic surgery are for more high quality studies to justify its cost. | Tony Wing Chung Mak Janet Fung Yee Lee Kaori Futaba Sophie Sok Fei Hon Dennis Kwok Yu Ngo Simon Siu Man Ng | 2014 | World Journal of Gastrointestinal Oncology2014，6，6： | 16 |
| 2 | 让肾脏健康人人可享,处处可及——从预防到诊治显示文摘Around 850 million people currently are affected by different types of kidney disorders.Up to 1 in 10 adults worldwide has chronic kidney disease(CKD),which is invariably irreversible and mostly progressive.The global burden of CKD is increasing,and CKD is projected to become the fifth most common cause of years of life lost globally by 2040.If CKD remains uncontrolled and if the affected person survives the ravages of cardiovascular and other complications of the disease,CKD progresses to endstage kidney disease,where life cannot be sustained without dialysis therapy or kidney transplantation.Hence,CKD is a major cause of catastrophic health expenditure. | Philip Kam Tao Guillermo Garcia Garcia Siu Fai Lui Sharon Andreoli Winston Wing Shing Fung Anne Hradsky Latha Kumaraswami Vassilios Liakopoulos Ziyoda Rakhimova Gamal Saadi Luisa Strani Ifeoma Ulasi Kamyar Kalantar Zadeh 无 | 2020 | 肾脏病与透析肾移植杂志2020，29，1： | 6 |
| 3 | Importance of surgical margin in the outcomes of hepatocholangiocarcinoma显示文摘AIM To evaluate the significance of resection margin width in the management of hepatocholangiocarcinoma(HCC-CC).METHODS Data of consecutive patients who underwent hepatectomy for hepatic malignancies in the period from1995 to 2014 were reviewed.Patients with pathologically confirmed HCC-CC were included for analysis.Demographic,biochemical,operative and pathological data were analyzed against survival outcomes. RESULTSForty-two patients were included for analysis.The median age was 53.5 years.There were 29 males.Hepatitis B virus was identified in 73.8%of the patients.Most patients had preserved liver function.The median preoperative indocyanine green retention rate at 15 min was 10.2%.The median tumor size was 6.5 cm.Major hepatectomy was required in over 70%of the patients.Hepaticojejunostomy was performed in 6 patients.No hospital death occurred.The median hospital stay was 13 d.The median follow-up period was 32 mo.The 5-year disease-free survival and overall survival were 23.6%and 35.4%respectively.Multifocality was the only independent factor associated with diseasefree survival[P<0.001,odds ratio 4,95%confidence interval(CI):1.9-8.0].In patients with multifocal tumor(n=20),resection margin of≥1 cm was associated with improved 1-year disease-free survival(40%vs 0%;log-rank,P=0.012).CONCLUSIONHCC-CC is a rare disease with poor prognosis.Resection margin of 1 cm or above was associated with improved survival outcome in patients with multifocal HCC-CC. | Ka Wing Ma Kenneth Siu Ho Chok | 2017 | World Journal of Hepatology2017，9，13： | 5 |
| 4 | Chinese topical herbal medicine gives additive effect on pharmaceutical agent on fracture healing显示文摘OBJECTIVE:To investigate the efficacy on the combination of oral strontium ranelate(Sr R)with a topical Chinese herbal paste on facilitation of fracture healing.METHODS:An open fracture was created at the mid-shaft of the right tibia of rat.A herbal pastecalled CDR containing Honghua(Flos Carthami),Chuanxuduan(Radix Dipsaci Asperoidis)and Dahuang(Radix Et Rhizoma Rhei Palmati)was prepared.The rats were treated with either CDR topically on the fracture site,or Sr R orally,or their combinations.Bone turnover biochemical markers in serum were measured.Microarchitecture of the fracture was analyzed using micro-CT after 14 and 28 d,followed by histomorphometrical analysis.RESULTS:Micro-computed tomography analysis revealed that the combined treatment of CDR with600 mg/g Sr R significantly increased the total callus density,mineralized callus volume fraction,mineralized callus mineral content and mineralized callus density of the callus after 28 d of treatment.This result was consistent with the histomorphometrical analysis on the osteoid volume.Analysis of biochemical markers showed that the combined treatments reduced the bone resorption that occurs temporarily after fracture.CONCLUSION:This study demonstrated that the combined treatment of oral Sr R and topical CDR is effective to promote fracture healing by their additive effect on promoting bone formation and retarding bone resorption. | Siu Wing Sum Shiu Hoi Ting Shum Wai Ting Ko Chun Hay Lau Clara Bik San Hung Leung Kim Leung Ping Chung | 2019 | Journal of Traditional Chinese Medicine2019，39，6： | 4 |
| 5 | Magnetoelectric and converse magnetoelectric responses in Tb_xDy_(1-x)Fe_(2-y) alloy & Pb(Mg_(1/3)Nb_(2/3))_(1-x)Ti_xO_3 crystal laminated composites显示文摘Measured results of magnetoelectric (ME) and converse magnetoelectric (CME) effects of TbxDy1-xFe2-y/ Pb(Mg1/3Nb2/3)(1-x)TixO3/TbxDy1-xFe2-y (TD/PMNT/TD) and PMNT/TD/PMNT laminated composites are pre- sented. ME effect was determined by measuring laminate voltage output under a Helmholtz-gener- ated AC field biased by a DC field (0―1 kOe) (1 Oe = 79.58 A/m). The CME effect was measured by re- cording the voltage induced in a solenoid encompassing the ME sample while exposed to a DC bias field and PMNT layer driven by a 10 V AC source. The ME and CME responses in the two laminated structure are linear. The highest values of ME coefficients in TD/PMNT/TD and PMNT/TD/PMNT com- posites are 384 mV/Oe and 158 mV/Oe, respectively, while the highest values of CME coefficients in the two composites are 118 mG/V and 162 mG/V (1 G=10-4 T), respectively. | JIA YanMin LUO HaoSu OR Siu Wing WANG YaoJin CHAN Helen L W | 2008 | Chinese Science Bulletin2008，53，14： | 3 |

| 7 | 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 |
| 9 | Maintenance therapy in advanced non-small cell lung cancer: a prime-time for change?显示文摘Lung cancer is the leading cancer in terms of incidence and mortality in China and its incidence in China is predicted to increase in the next 20 years.1 The majority of the lung cancer patients are diagnosed with advanced stage disease,for which chemotherapy or targeted therapies are the mainstay palliative treatments.Before the identification of single-driver mutations,like the epidermal growth factor receptor (EGFR) mutation,platinum-based doublet was the standard first line treatment for advanced stage nonsmall cell lung cancer (NSCLC) patients with a good performance status (PS).However,patient prognosis remains poor and the modest treatment efficacy seems to have reached a plateau despite newer generation of platinum doublets.2 The recommendation for the duration of first line platinum doublet treatment is 4-6 cycles.3 The paradigm was based on the fact that a protracted course of chemotherapy did not prolong survival but introduced cumulative toxicities.4,5 The use of maintenance therapy (MT),defined by Grossi et al6 as the prolongation of chemotherapy with the administration of additional drugs at the end of a defined number of initial chemotherapy cycles after achieving maximum tumor response,was not considered as a standard option in the past. | Oscar Siu Hong Chan Rebecca Mei WanYeung Anne Wing Mui Lee | 2013 | Chinese Medical Journal2013，，12： | 2 |

| 11 | 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 |
