2Robotic 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 2014World Journal of Gastrointestinal Oncology2014,6,6:16
3Telerobotic-assisted laparoscopic abdominoperineal resection for low rectal cancer: Report of the first case in Hong Kong and China with an updated literature review显示文摘Telerobotic surgery is the most advanced development in the field of minimally invasive surgery. The da Vinci surgical system, which is currently the most widely used telerobotic device, was approved by the Food and Drug Administration of the United States of America for clinical use in all abdominal operations in July 2000. The first da Vinci surgical system in China was installed in November 2005 at our institution. We herein report the first telerobotic-assisted laparoscopic abdominoperineal resection using the 3-arm da Vinci surgical system for low rectal cancer in Hong Kong and China, which was performed in August 2006. The operative time and blood loss were 240 min and 200 mL, respectively. There was no complication, and the patient was discharged on postoperative day five. An updated review of published literature on telerobotic-assisted colorectal surgery is included in this report, with special emphasis on its advantages and limitations.Simon Siu-Man Ng Janet Fung-Yee Lee Raymond Ying-Chang Yiu Jimmy Chak-Man Li Sophie Sok-Fei Hon 2007World Journal of Gastroenterology2007,13,17:12
4A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis.Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao 2016Chinese Journal of Cancer2016,35,6:10

6Impacts of different drying strategies on drying characteristics,the retention of bio-active ingredient and colour changes of dried Roselle显示文摘The drying kinetics of Roselle(Hibiscus sabdariffa L) of variety Terengganu(UMKL-1) and the quality attribution of Roselle were studied. The experiments were conducted using four different drying methods, including solar greenhouse drying(SD), solar greenhouse with intermittent heat pump drying(SIHP), hot air drying(HA) and heat pump drying(HP). Among the four drying methods, HP achieved the highest drying rate at a range from0.054 g H_2 O·(g DM)^(-1) ·min^(-1) to 0.212 g H_2 O·(g DM)^(-1)·min^(-1) while SD had the lowest drying rate, measured at 0.042 g H_2 O·(g DM)^(-1)·min^(-1).The analysis on colour kinetics revealed that there is no significant colour loss(p > 0.05) observed from HP's dried Roselle. Greater amount of flavonoid compounds i.e. protocatechuic acid was found in SD and SIHP dried finished product whereas HP's dried Roselle contains higher percentage of catechin as compared to other drying methods.Thing Chai Tham Mei Xiang Ng Shu Hui Gan Lee Suan Chua Ramlan Aziz Luqman Chuah Abdullah Sze Pheng Ong Nyuk Ling Chin Chung Lim Law 2018Chinese Journal of Chemical Engineering2018,26,2:7
7Role and outcome of conventional surgery in the treatment of pyogenic liver abscess in the modern era of minimally invasive therapy显示文摘AIM:To evaluate the role and outcome of conventional surgery in the treatment of pyogenic liver abscess in the modern era of minimally invasive therapy. METHODS:The medical records of thirteen patients with pyogenic liver abscess who underwent surgical treatment between January 1995 and December 2002 were retrospectively reviewed to determine the clinical presentation, indication and nature of surgery, and out-come of surgery. RESULTS:The patients were predominantly women (10/13) with a mean age of 65 ± 17 years. Their main presenting symptoms were abdominal pain (100%) and fever (77%). The aetiologies included biliary (n = 6), cryptogenic (n = 3), portal (n = 2), and trauma (n = 2). Seven patients underwent percutaneous drainage as the initial treatment. Of these, three patients developed peritonitis secondary to peritoneal spillage. Another four patients failed to respond because of multilocula-tion. Salvage surgery was required in these patients. Six patients proceeded to straight laparotomy:two had marked sepsis and multiloculated abscess that precluded percutaneous drainage, and four presented with perito-nitis of uncertain pathology. Surgical procedures included deroofment and drainage (n = 9), liver resection (n = 3), peritoneal lavage (n = 2), cholecystectomy (n = 4), and exploration of common bile duct (n = 2). One patient required reoperation because of bleeding. Three patients required further percutaneous drainage after surgery. The overall mortality was 46%. Four patients died of multiorgan failure and two patients died of pulmonary embolism. CONCLUSION:Surgical treatment of pyogenic liver ab-scess is occasionally needed when percutaneous drainage has failed due to various reasons. Mortality rate in this group of patients has remained high.Simon Siu-Man Ng Janet Fung-Yee Lee Paul Bo-San Lai 2008World Journal of Gastroenterology2008,14,5:7

9Intraluminal versus infiltrating gallbladder carcinoma:Clinical presentation,ultrasound and computed tomography显示文摘AIM: To compare clinical presentation and ultrasound (US) and computed tomography (CT) sensitivity between intraluminal and inf iltrating gallbladder carcinoma (GBCA). METHODS: This retrospective study evaluated 65 cases of GBCA that were categorized morphologically into the intraluminal-GBCA (n = 37) and infiltrating-GBCA(n = 28) groups. The clinical and laboratory fi ndings, presence of gallstones, gallbladder size, T-staging, nodal status, sensitivity of preoperative US and CT studies, and outcome were compared between the two groups.RESULTS: There were no signif icant differences between the two groups with respect to female predominance, presence of abdominal pain, serum aminotransferases level, T2-T4 staging, and regional metastatic nodes. Compared with the patients with intraluminal-GBCA, those with infiltrating-GBCA were significantly older (65.49 ± 1.51 years vs 73.07 ± 1.90 years), had a higher frequency of jaundice (3/37 patients vs 13/28 patients) and fever (3/37 patients vs 10/28 patients), higher alkaline phosphatase (119.36 ± 87.80 IU/L vs 220.68 ± 164.84 IU/L) and total bilirubin (1.74 ± 2.87 mg/L vs 3.50 ± 3.51 mg/L) levels, higher frequency of gallstones (12/37 patients vs 22/28 patients), smaller gallbladder size (length, 7.47 ± 1.70 cm vs 6.47 ± 1.83 cm; width, 4.21 ± 1.43 cm vs 2.67 ± 0.93 cm), and greater proportion of patients with < 12 mo survival (16/37 patients vs 18/28 patients). The sensitivity for diagnosing intraluminal-GBCA with and without gallstones was 63.6% and 91.3% by US, and 80% and 100% by CT, respectively. The sensitivity for diagnosing inf iltrating-GBCA with and without gallstones was 12.5% and 25% by US, and 71.4% and 75% by CT, respectively. CONCLUSION: In elderly women exhibiting small gallbladder and gallstones on US, especially those with jaundice, fever, high alkaline phosphatase and bilirubin levels, CT may reveal concurrent infi ltrating-GBCA.Tze-Yu Lee Sheung-Fat Ko Chung-Cheng Huang Shu-Hang Ng Jiun-Lung Liang Hsuan-Ying Huang Min-Chi Chen Shyr-Ming Sheen-Chen 2009World Journal of Gastroenterology2009,15,45:7

11Advances in lithium niobate photonics:development status and perspectives显示文摘Lithium niobate(LN)has experienced significant developments during past decades due to its versatile properties,especially its large electro-optic(EO)coefficient.For example,bulk LN-based modulators with high speeds and a superior linearity are widely used in typical fiber-optic communication systems.However,with everincreasing demands for signal transmission capacity,the high power and large size of bulk LN-based devices pose great challenges,especially when one of its counterparts,integrated silicon photonics,has experienced dramatic developments in recent decades.Not long ago,high-quality thin-film LN on insulator(LNOI)became commercially available,which has paved the way for integrated LN photonics and opened a hot research area of LN photonics devices.LNOI allows a large refractive index contrast,thus light can be confined within a more compact structure.Together with other properties of LN,such as nonlinear/acousto-optic/pyroelectric effects,various kinds of high-performance integrated LN devices can be demonstrated.A comprehensive summary of advances in LN photonics is provided.As LN photonics has experienced several decades of development,our review includes some of the typical bulk LN devices as well as recently developed thin film LN devices.In this way,readers may be inspired by a complete picture of the evolution of this technology.We first introduce the basic material properties of LN and several key processing technologies for fabricating photonics devices.After that,various kinds of functional devices based on different effects are summarized.Finally,we give a short summary and perspective of LN photonics.We hope this review can give readers more insight into recent advances in LN photonics and contribute to the further development of LN related research.Guanyu Chen Nanxi Li Jun Da Ng Hong-Lin Lin Yanyan Zhou Yuan Hsing Fu Lennon Yao Ting Lee Yu Yu Ai-Qun Liu Aaron J.Danner 2022Advanced Photonics2022,4,3:6
12Quality of life after laparoscopic vs open sphincter-preserving resection for rectal cancer显示文摘AIM: To compare quality of life (QoL) outcomes in Chinese patients after curative laparoscopic vs open surgery for rectal cancer. METHODS: Eligible Chinese patients with rectal cancer undergoing curative laparoscopic or open sphincterpreserving resection between July 2006 and July 2008 were enrolled in this prospective study. The QoL outcomes were assessed longitudinally using the validated Chinese versions of the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQCR38 questionnaires before surgery and at 4, 8, and 12 mo after surgery. The QoL scores at the different time points were compared between the laparoscopic and open groups. A higher score on a functional scale indicated better functioning, whereas a higher score on a symptom scale indicated a higher degree of symptoms.RESULTS: Seventy-four patients (49 laparoscopic and 25 open) were enrolled. The two groups of patients were comparable in terms of sociodemographic data, types of surgery, tumor staging, and baseline mean QoL scores. There was no significant decrease from baseline in global QoL for the laparoscopic group at different time points, whereas the global QoL was worse compared to baseline beginning at 4 mo but returned to baseline by 12 mo for the open group (P = 0.019, Friedman test). Compared to the open group, the laparoscopic group had significantly better physical (89.9±1.4 vs 79.2±3.7, P = 0.016), role (85.0±3.4 vs 63.3±6.9, P = 0.005), and cognitive (73.5±3.4 vs 50.7±6.2, P = 0.002) functioning at 8 mo, fewer micturition problems at 4-8 mo (4 mo: 32.3±4.7 vs 54.7±7.1, P = 0.011; 8 mo: 22.8±4.0 vs 40.7±6.9, P = 0.020), and fewer male sexual problems from 8 mo onward (20.0±8.5 vs 76.7±14.5, P = 0.013). At 12 mo after surgery, no significant differences were observed in any functional or symptom scale between the two groups, with the exception of male sexual problems, which remained worse in the open group (29.2±11.3 vs 80.0±9.7, P = 0.026). CONCLUSION: Laparoscopic sphincter-preserving resection for rectal cancer is associated with better preservation of QoL and fewer male sexual problems when compared with open surgery in Chinese patients. These findings, however, should be interpreted with caution because of the small sample size of the study.Simon Siu-Man Ng Wing-Wa Leung Cherry Yee-Ni Wong Sophie Sok-Fei Hon Tony Wing-Chung Mak Dennis KwokYu Ngo Janet Fung-Yee Lee 2013World Journal of Gastroenterology2013,19,29:6
13同型半胱氨酸水平、MTHFR基因突变与原发性高血压的病例对照研究(英文)显示文摘探讨升高的同型半胱氨酸水平、MTHFR基因突变与原发性高血压的关系。方法:从上海一个社区中随机选取127例35~75岁的原发性高血压病人和170例正常血压者。采用聚合酶链反应-限制性片段长度多态性分析MTHFR基因多态性。使用高效液相色谱结合电化学方法检测血清中同型半胱氨酸总浓度,使用放射免疫法同时测定血清中叶酸和B_(12)浓度。结果:调整年龄和性别后,病例和对照组同型半胱氨酸水平分别为 10.56 μmol/L和 10.34 μmol/L,差异无显著性(P=0.63)。在未服降压药的对象中同型半胱氨酸浓度与收缩压和舒张压亦无关联。该人群MTHFR不耐热性基因突变频率为13.1%,突变等位基因频率为38.7%。病例组与对照组基因型分布和突变等位基因频率无显著性差异。然而,病例组叶酸和B_(12)浓度高于对照组。结论:本研究未发现升高的同型半胱氨酸水平、MTHFR基因突变是原发性高血压的独立危险因素。高血压病人较高的叶酸和B_(12)水平可能降低了同型半胱氨酸的危险性。詹思延 高原原 尹香君 胡永华 李立明 Vivian Ng Lee BL Ong CN 2000高血压杂志2000,8,1:5

15Portal venous gas and thrombosis in a Chinese patient with fulminant Crohn’s colitis: A case report with literature review显示文摘Ever since its earliest reports, portal venous gas (PVG) has been associated with numerous intraabdominal catastrophes and has served as an indication for urgent surgical exploration. It is traditionally regarded to be an ominous finding of impending death, with highest mortality reported in patients with underlying bowel ischemia. Today, computed tomography has demonstrated a wider range of clinical conditions associated with PVG, some of which are ‘benign’ and do not necessarily require surgery, unless when there are signs of intraabdominal catastrophe or systemic toxicity. One of these ‘benign’ conditions is Crohn’s disease. The present report describes a 19-year-old Chinese boy with Crohn’s pancolitis who presented with septic shock associated with PVG and portal vein thrombosis, and was successfully managed surgically. To our knowledge, this is the fi rst report of PVG and portal vein thrombosis associated with Crohn’s disease in a Chinese patient. In addition, we have also reviewed the reports of another 18 Crohn’s patients with PVG previously described in the English literature. Specifi c predisposing factors for PVG were identified in 8 patients, including barium enema, colonoscopy, blunt abdominal trauma, and enterovenous f istula. The patients who developed PVG following barium enema and blunt trauma were all asymptomatic and no specifi c treatment was necessary. Eleven patients (58%) who presented with signs of intraabdominal catastrophe or systemic toxicity required either immediate or eventual surgery. The overall mortality rate among the 19 patients was only 11%. The present literature review has shown that the f inding of PVG associated with Crohn’ s disease does not always mandate surgical intervention. It is the clinical features and the related complications that ultimately determine the treatment approaches. The overall outcome of PVG associated with Crohn’s disease has been favourable.Simon Siu-Man Ng Raymond Ying-Chang Yiu Janet Fung-Yee Lee Jimmy Chak-Man Li Ka-Lau Leung 2006World Journal of Gastroenterology2006,12,34:4

19Infant intestinal Enterococcus faecalis down-regulates inflammatory responses in human intestinal cell lines显示文摘AIM: To investigate the ability of Lactic acid bacteria (LAB) to modulate inflammatory reaction in human intestinal cell lines (Caco-2, HT-29 and HCT116). Different strains of LAB isolated from new born infants and fermented milk, together with the strains obtained from culture collections were tested.METHODS: LABs were treated with human intestinal cell lines. ELISA was used to detect IL-8 and TGF-β protein secretion. Cytokines and Toll like receptors (TLRs) gene expression were assessed using RT-PCR. Conditional medium, sonicated bacteria and UV killed bacteria were used to find the effecter molecules on the bacteria. Carbohydrate oxidation and protein digestion were applied to figure out the molecules' residues. Adhesion assays were further carried out.RESULTS: It was found that Enterococcus faecalis is the main immune modulator among the LABs by downregulation of IL-8 secretion and upregulation of TGF-β. Strikingly, the effect was only observed in four strains of E. faecalis out of the 27 isolated and tested. This implies strain dependent immunomodulation in the host. In addition, E. faecalis may regulate inflammatory responses through TLR3, TLR4, TLR9 and TRAF6. Carbohydrates on the bacterial cell surface are involved in both its adhesion to intestinal cells and regulation of inflammatory responses in the host. CONCLUSION: These data provide a case for the modulation of intestinal mucosal immunity in which specific strains of E. faecalis have uniquely evolved to maintain colonic homeostasis and regulate inflammatory responses.Lydia Hui Mei Ng Wai Ling Chow Yuan Kun Lee 2008World Journal of Gastroenterology2008,14,7:4
