| 1 | 胃癌预防亚太地区共识指南显示文摘背景与目的:胃癌是亚太地区的主要健康负担之一,但对其预防策略尚缺乏共识。本共识会议旨在评价预防胃癌的策略。方法:多学科专家组应用德尔菲(Delphi)法制订共识条文,提呈相关数据,对证据等级、推荐强度以及共识水平予以分级。结果:幽门螺杆菌(H.pylori)感染是非贲门胃腺癌必要但非充分的致病因子。盐的高摄入与胃癌强烈相关。新鲜果蔬对胃癌具有预防作用,但维生素和其他饮食补充并不能预防胃癌。H.pylori感染中的宿主-细菌相互作用导致不同类型的胃炎和胃酸分泌,从而决定疾病结局。胃癌阳性家族史是一个重要的危险因素。低血清胃蛋白酶原反映胃萎缩程度,可作为检出胃癌高危人群的标志物。H.pylori筛查和治疗被推荐作为减少高危人群胃癌危险性的一种策略,该策略在萎缩性胃炎发生前实施最为有效,但并不排除对胃癌高危人群的内镜监测。对胃癌低危人群不推荐行H.pylori筛查。H.pylori感染的一线治疗应遵循国家治疗指南。结论:高危人群中H.pylori筛查和根除策略可能会减少胃癌的发生率,本共识根据现有证据予以推荐。 | Kwong Ming Fock Nick Talley Paul Moayyedi Richard Hunt Takeshi Azuma Kentaro Sugano Shu Dong Xiao Shiu Kum Lam Khean Lee Goh Tsutomu Chiba Naomi Uemura Jae G Kim Nayoung Kim Tiing Leong Ang Varocha Mahachai Hazel Mitchell Abdul Aziz Rani Jyh Ming Liou Ratha-korn Vilaichone Jose Sollanor 钱本余 | 2008 | 胃肠病学2008，13，4： | 37 |
| 2 | Effect of sinter layer porosity distribution on flow and temperature fields in a sinter cooler显示文摘When sinters are filled into the sinter cooler from the sintering machine, it is commonly seen that, due to segregation effects, sinters of larger size usually accumulate closer to the inner wall of the sinter cooler, whereas those of smaller size are to the outer wall. This nonuniform distribution of sinters has led to uneven cooling effect throughout the cooler. This causes the sinters leaving the cooler at a large temperature difference. This undesired temperature difference leads to the deformation and even the destruction of the conveyors. The computational fluid dynamics (CFD) technique was used in the present work to investigate the heat and fluid flow phenomena within the sinter cooler corresponding to the different distribution of sinter layer porosity, which was highly dependent on the arrangement and orientation of sinters within the sinter cooler. It is confirmed that a high mass flow rate within the sinter layer causes a low temperature region and vice versa. The flow fields for vertically reducing porosity distribution and random distribution are almost identical indicating the relative insignificance of convective heat transfer mechanism. | Jik-chang Leong Kai-wun Jin Jia-shyan Shiau Tzer-ming Jeng Chang-hsien Tai | 2009 | International Journal of Minerals,Metallurgy and Materials2009，16，3： | 27 |
| 3 | 亚太地区胃食管反流病的处理共识:更新版显示文摘背景与目的:自从2004年亚太地区胃食管反流病(GERD)共识发表以来,更多关于GERD流行病学和处理的文献资料相继出现。有必要对这些资料进行循证综述,对共识作出更新。方法:由多学科专家组应用德尔菲(Delphi)法制定共识条文,提呈相关资料,并对证据质量、推荐力度和共识水平进行分级。结果:亚洲GERD发生率日益增加。其危险因素包括老年、男性、种族、家族史、社会经济地位高、体重指数增加和吸烟。对于有典型症状而无报警症状的患者,对质子泵抑制剂(PPI)试验有症状应答具有诊断意义。如PPI试验失败,停止治疗后pH监测结果阴性可排除GERD。窄带成像、胶囊内镜检查和无线pH监测的作用尚未明确。亚洲诊断策略的制定须考虑到并存的胃癌和消化性溃疡。减轻体质量和抬高床头可改善反流症状。PPIs是最有效的内科治疗手段。对于非糜烂性反流病(NERD)患者,按需治疗较为适宜。有慢性咳嗽、喉炎和典型GERD症状的患者在排除非GERD病因后,应予PPI每天两次治疗。如有经验丰富的外科医师,GERD患者可行胃底折叠术。除临床试验外,GERD不应采用内镜治疗。结论:新的诊断方法和内镜治疗的作用有待进一步研究阐明。亚洲GERD诊断策略的制定须考虑到并存的胃癌和消化性溃疡。PPIs仍为治疗的基石。 | Kwong Ming Fock Nicholas J Talley Ronnie Fass Khean Lee Goh Peter Katelaris Richard Hunt Michio Hongo Tiing Leong Ang Gerald Holtmann Sanjay Nandurkar San Ren Lin Benjamin CY Wong Francis KL Chan Abdul Aziz Rani Young-Tae Bak Jose Sollano Khek Yu Ho Sathoporn Manatsathit 钱本余 | 2008 | 胃肠病学2008，13，7： | 21 |
| 4 | MicroRNA-21 as a potential colon and rectal cancer biomarker显示文摘Colorectal cancer(CRC)is one of the most common malignant diseases worldwide and the prognosis is still poor although much progress has been achieved in recent years.In order to reduce CRC-related deaths,many studies are aimed at identifying novel screeningand prognosis-related biomarkers.MicroRNAs(miRNAs)are a class of 18-27-nucleotide single-stranded RNA molecules that regulate gene expression at the posttranscriptional level.It has been demonstrated that miRNAs regulate a variety of physiological functions,including development,cell differentiation,proliferation,and apoptosis.They play important roles in various physiologic and developmental processes and in the initiation and progression of various human cancers.It has been shown that miRNAs can critically regulate tumor cell gene expression,and evidence suggests that they may function as both oncogenes and tumor suppressor genes.In CRC,miRNAs-21 is one of the most important miRNAs and is rapidly emerging as a novel biomarker in CRC,with good potential as a diagnostic and therapeutic target.In this review,we summarize the latest research findings of the clinicopathological relevance of miRNAs-21 in CRC initiation,development,and progress,highlighting its potential diagnostic,prognostic,and therapeutic application,as well as discuss-ing future prospects. | Tao Li Mei Ha Leong Bruce Harms Gregory Kennedy Lin Chen | 2013 | World Journal of Gastroenterology2013，19，34： | 16 |
| 5 | miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium. | Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey | 2011 | World Journal of Gastroenterology2011，17，8： | 13 |

| 7 | Evolution of laparoscopy in colorectal surgery:An evidencebased review显示文摘Open surgery for colorectal disease has progressed significantly over the past century from humble beginnings to form the mainstay of treatment for colorectal cancer and a number of benign conditions.Following the introduction of laparoscopic abdominal surgery,the next stage in the evolution of the specialty began in the 1990s with the first laparoscopic colonic resection.Following some early concerns regarding its safety and oncological efficacy during the latter part of that decade,laparoscopic colorectal surgery rapidly came into mainstream use in the early part of the current century with evidence supporting its use being made available from large scale randomised controlled trials.This article provides an evidence-based summary of this evolutionary process as it relates to both benign and malignant colorectal disease,as well as discussion of the next phase of new technologies such as robotic surgery. | Alexander Emmanuel Blackmore Mark Te Ching Wong Choong Leong Tang | 2014 | World Journal of Gastroenterology2014，20，17： | 12 |

| 9 | Temporal Variations of the Frontal and Monsoon Storm Rainfall during the First Rainy Season in South China显示文摘The temporal variations in storm rainfall during the first rainy season (FRS) in South China (SC) are investigated in this study. The results show that the inter-annual variations in storm rainfall during the FRS in SC seem to be mainly influenced by the frequency of storm rainfall, while both frequency and intensity affect the inter-decadal variations in the total storm rainfall. Using the definitions for the beginning and ending dates of the FRS, and the onset dates of the summer monsoon in SC, the FRS is further divided into two sub-periods, i.e., the frontal and monsoon rainfall periods. The inter-annual and inter-decadal variations in storm rainfall during these two periods are investigated here. The results reveal a significant out-of-phase correlation between the frontal and monsoon storm rainfall, especially on the inter-decadal timescale, the physical mechanism for which requires further investigation. | YUAN Fang WEI Ke CHEN Wen FONG Soi Kun LEONG Ka Cheng | 2010 | Atmospheric and Oceanic Science Letters2010，3，5： | 10 |
| 10 | Systematic review of the outcomes of surgical resection for intermediate and advanced Barcelona Clinic Liver Cancer stage hepatocellular carcinoma:A critical appraisal of the evidence显示文摘AIM To perform a systematic review to determine the survival outcomes after curative resection of intermediate and advanced hepatocellular carcinomas(HCC).METHODS A systematic review of the published literature was performed using the PubM ed database from 1 st January 1999 to 31 st Dec 2014 to identify studies that reported outcomes of liver resection as the primary curative treatment for Barcelona Clinic Liver Cancer(BCLC) stage B or C HCC. The primary end point was to determine the overall survival(OS) and disease free survival(DFS) of liver resection of HCC in BCLC stage B or C in patients with adequate liver reserve(i.e., Child's A or B status). The secondary end points were to assess the morbidity and mortality of liver resection in large HCC(defined as lesions larger than 10 cm in diameter) and to compare the OS and DFS after surgical resection of solitary vs multifocal HCC.RESULTS We identified 74 articles which met the inclusion criteria and were analyzed in this systematic review. Analysis of the resection outcomes of the included studies were grouped according to(1) BCLC stage B or C HCC,(2) Size of HCC and(3) multifocal tumors. The median 5-year OS of BCLC stage B was 38.7%(range 10.0-57.0); while the median 5-year OS of BCLC stage C was 20.0%(range 0.0-42.0). The collective median 5-year OS of both stages was 27.9%(0.0-57.0). In examining the morbidity and mortality following liver resection in large HCC, the pooled RR for morbidity [RR(95%CI) = 1.00(0.76-1.31)] and mortality [RR(95%CI) = 1.15(0.73-1.80)] were not significant. Within the spectrum of BCLC B and C lesions, tumors greater than 10 cm were reported to have median 5-year OS of 33.0% and multifocal lesions 54.0%.CONCLUSION Indication for surgical resection should be extended to BCLC stage B lesions in selected patients. Further studies are needed to stratify stage C lesions for resection. | Ye Xin Koh Hwee Leong Tan Weng Kit Lye Juinn Huar Kam Adrian Kah Heng Chiow Siong San Tan Su Pin Choo Alexander Yaw Fui Chung Brian Kim Poh Goh | 2018 | World Journal of Hepatology2018，10，6： | 10 |
| 11 | Efficacy of small-volume simethicone given at least 30 min before gastroscopy显示文摘AIM To evaluate the efficacy of 5 m L simethicone solution in decreasing gastric foam if given at least 30 min before gastroscopy.METHODS This was a randomized, placebo controlled, endoscopist blinded study performed at Changi General Hospital. Patients were at least 21 years old, had no prior sur-gical resection of the upper gastrointestinal tract, and scheduled for elective diagnostic gastroscopies. The primary outcome was the total mucosal visibility score(TMVS) which was evaluated using Mc Nally score. The sample size was calculated to be 24 per group(SD 2.4, 80% power, P < 0.05, 2-sample t test). RESULTS Fifty-four patients were randomised to receive either simethicone [1 m L liquid simethicone(100 mg) in 5 m L of water] or placebo(5 m L of water) at least 30 min before their gastroscopy. Six accredited consultants conductedthe gastroscopy, and the interobserver agreement of scoring TMVS was good with a Kappa statistic of 0.73. The simethicone group had significantly better mean TMVS compared to placebo(5.78 ± SD 1.65 vs 8.89 ± SD 1.97, P < 0.001). The improvement was statistically significant for the duodenum and the gastric antrum, angularis, body, and fundus. Percent 51.9 of patients in the simethicone group had a TMVS of 4(no bubbles at all) to 5(only 1 area with minimal bubbles), while in the placebo group 3.7% of patients had TMVS of 4 or 5. The number needed to treat was 2.1 to avoid a TMVS of 6 and more. The simethicone group also had a significantly shorter procedure time with less volume of additional flushes required during gastroscopy to clear away obscuring gastric foam.CONCLUSION With a premedication time of at least 30 min, 5 m L simethicone can significantly decrease gastric foam, decrease the volume of additional flushes, and shorten gastroscopy time. | Mingjun Song Andrew Boon Eu Kwek Ngai Moh Law Jeannie Peng Lan Ong Jessica Yi-Lyn Tan Prem Harichander Thurairajah Daphne Shih Wen Ang Tiing Leong Ang | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，4： | 10 |

| 13 | Primary sclerosing cholangitis as an independent risk factor for colorectal cancer in the context of inflammatory bowel disease: A review of the literature显示文摘To examine and evaluate recent evidence regarding the epidemiology, pathogenesis and management of colorectal cancer(CRC) development in inflammatory bowel disease(IBD)-primary sclerosing cholangitis(PSC) patients. Using the PubMed database, a literature search was conducted for relevant articles in English from the past 10 years. Relevant studies investigating PSC as a risk factor for CRC in IBD in the context of incidence and prevalence, pathogenesis, prevention and prognosis were included in this review. Recent evidence increasingly points to PSC as a significant risk factor in the development of CRC in patients with concomitant IBD. PSC may be an important risk factor for CRC in different populations worldwide. The mechanism for this increase in risk is still unclear. The efficacy of UDCA as a chemopreventive agent remains controversial. Liver transplantation does not halt the development of CRC, although there is not enough evidence to suggest that it is associated with increased incidence of CRC. While routine colonoscopic surveillance should be performed in patients with concurrent PSC and IBD, more high-level evidence is required to support the benefits of the procedure. While many new developments have taken place in the last decade, the pathogenesis and optimal management of CRC development in IBD-PSC patients remain unclear. | Rosy Wang Rupert Leong | 2014 | World Journal of Gastroenterology2014，20，27： | 8 |
| 14 | Advances in adjuvant systemic therapy for non-small-cell lung cancer显示文摘Non-small-cell lung cancer remains a leading cause of death around the world. For most cases, the only chance of cure comes from resection for localised disease, however relapse rates remain high following surgery. Data has emerged over recent years regarding the utility of adjuvant chemotherapy for improving disease-free and overall survival of patients following curative resection. This paper reviews the clinical trials that have been conducted in this area along with the studies integrating radiation therapy in the adjuvant setting. The role of prognostic gene signatures are reviewed as well as ongoing clinical trials including those incorporating biological or targeted therapies. | David Leong Rajat Rai Brandon Nguyen Andrew Lee Desmond Yip | 2014 | World Journal of Clinical Oncology2014，5，4： | 7 |
| 15 | Comparative study and systematic review of laparoscopic liver resection for hepatocellular carcinoma显示文摘AIM: To compare the surgical outcomes between laparoscopic liver resection(LLR) and open liver resection(OLR) as a curative treatment in patients with hepatocellular carcinoma(HCC). METHODS: A Pub Med database search was performed systematically to identify comparative studies of LLR vs OLR for HCC from 2000 to 2014. An extensive text word search was conducted, using combinations of search headings such as 'laparoscopy', 'hepatectomy', and 'hepatocellular carcinoma'. A comparative study was also performed in our institution where we analysed surgical outcomes of 152 patients who underwent liver resection between January 2005 to December 2012, of which 42 underwent laparoscopic or hand-assisted laparoscopic resection and 110 underwent open resection. RESULTS: Analysis of our own series and a review of 17 high-quality studies showed that LLR was superior to OLR in terms of short-term outcomes, as patients in the laparoscopic arm were found to have less intraoperative blood loss, less blood transfusions, and a shorter length of hospital stay. In our own series, both LLR and OLR groups were found to have similar overall survival(OS) rates, but disease-free survival(DFS) rates were higher in the laparoscopic arm. CONCLUSION: LLR is associated with better short-term outcomes compared to OLR as a curative treatment for HCC. Long-term oncologic outcomes with regards to OS and DFS rates were found to be comparable in both groups. LLR is hence a safe and viable option for curative resection of HCC. | Wei Qi Leong Iyer Shridhar Ganpathi Alfred Wei Chieh Kow Krishnakumar Madhavan Stephen Kin Yong Chang | 2015 | World Journal of Hepatology2015，7，27： | 7 |

| 17 | Evidence based review of the impact of image enhanced endoscopy in the diagnosis of gastric disorders显示文摘Gastric cancer is the third most common cause of cancer-related death.Advanced stages of gastric cancersgenerally have grim prognosis.But,good prognosis can be achieved if such cancers are detected,diagnosed and resected at early stages.However,early gastric cancers and its precursors often produce only subtle mucosal changes and therefore quite commonly remain elusive at the conventional examination with white light endoscopy.Image-enhanced endoscopy makes mucosal lesions more conspicuous and can therefore potentially yield earlier and more accurate diagnoses.Recent years have seen growing work of research in support of various types of image enhanced endoscopy(IEE) techniques(e.g.,dye-chromoendoscopy;magnification endoscopy;narrow-band imaging;flexible spectral imaging color enhancement;and I-SCAN) for a variety of gastric pathologies.In this review,we will examine the evidence for the utilization of various IEE techniques in the diagnosis of gastric disorders. | Ikram Hussain Tiing Leong Ang | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，20： | 7 |
| 18 | miR-145 improves metabolic inflammatory disease through multiple pathways显示文摘Chronic inflammation plays a pivotal role in insulin resistance and type 2 diabetes,yet the mechanisms are not completely understood.Here,we demonstrated that serum LPS levels were significantly higher in newly diagnosed diabetic patients than in normal control.miR-145 level in peripheral blood mononuclear cells decreased in type 2 diabetics.LPS repressed the transcription of miR-143/145 cluster and decreased miR-145 levels.Attenuation of miR-145 activity by anti-miR-145 triggered liver inflammation and increased serum chemokines in C57BL/6 J mice.Conversely,lentivirus-mediated miR-145 overexpression inhibited macrophage infiltration,reduced body weight,and improved glucose metabolism in db/db mice.And miR-145 overexpression markedly reduced plaque size in the aorta in ApoE−/−mice.Both OPG and KLF5 were targets of miR-145.miR-145 repressed cell proliferation and induced apoptosis partially by targeting OPG and KLF5.miR-145 also suppressed NF-κB activation by targeting OPG and KLF5.Our findings provide an association of the environment with the progress of metabolic disorders.Increasing miR-145 may be a new potential therapeutic strategy in preventing and treating metabolic diseases such as type 2 diabetes and atherosclerosis. | Min He Nan Wu Man Cheong Leong Weiwei Zhang Zi Ye Rumei Li Jinyang Huang Zhaoyun Zhang Lianxi Li Xiao Yao Wenbai Zhou Naijia Liu Zhihong Yang Xuehong Dong Yintao Li Lili Chen Qin Li Xuanchun Wang Jie Wen Xiaolong Zhao Bin Lu Yehong Yang Qinghua Wang Renming Hu | 2020 | Journal of Molecular Cell Biology2020，12，2： | 7 |
| 19 | Second and third line treatment options for Helicobacter pylori eradication显示文摘Helicobacter pylori is a highly successful bacterium with a high global prevalence and the infection carries significant disease burden. It is also becoming increasingly difficult to eradicate and the main reason for this is growing primary antibiotic resistance rates in a world where antibiotics are frequently prescribed and readily available. Despite knowing much more about the bacterium since its discovery, such as its genomic makeup and pathogenesis, we have seen declining treatment success. Therefore, clinicians today must be prepared to face one, two or even multiple treatment failures, and should be equipped with sufficient knowledge to decide on the appropriate salvage therapy when this happens. This article discusses the factors contributing to treatment failure and reviews the second and thirdline treatment strategies that have been investigated. Established empiric second line treatment options include both bismuth based quadruple therapy and levofloxacin based triple therapy. Antibiotic testing is recommended prior to initiating third line treatment. In the event that antibiotic susceptibility testing is unavailable, third line treatment options include rifabutin, rifaximin and sitafloxacin based therapies. | Mingjun Song Tiing Leong Ang | 2014 | World Journal of Gastroenterology2014，20，6： | 7 |
| 20 | Gastric peritoneal carcinomatosis-a retrospective review显示文摘AIM To characterize patients with gastric peritoneal carcinomatosis(PC) and their typical clinical and treatment course with palliative systemic chemotherapy as the current standard of care.METHODS We performed a retrospective electronic chart review of all patients with gastric adenocarcinoma with PC diagnosed at initial metastatic presentation between January 2010 and December 2014 in a single tertiary referral centre.RESULTS We studied a total of 271 patients with a median age of 63.8 years and median follow-up duration of 5.1 mo. The majority(n = 217, 80.1%) had the peritoneum as the only site of metastasis at initial presentation. Palliative systemic chemotherapy was eventually planned for 175(64.6%) of our patients at initial presentation, of which 171 were initiated on it. Choice of first-line regime was in accordance with the National Comprehensive Cancer Network Guidelines for Gastric Cancer Treatment. Thesepatients underwent a median of one line of chemotherapy, completing a median of six cycles in total. Chemotherapy disruption due to unplanned hospitalizations occurred in 114(66.7%), while cessation of chemotherapy occurred in 157(91.8%), with 42 cessations primarily attributable to PC-related complications. Patients who had initiation of systemic chemotherapy had a significantly better median overall survival than those who did not(10.9 mo vs 1.6 mo, P < 0.001). Of patients who had initiation of systemic chemotherapy, those who experienced any disruptions to chemotherapy due to unplanned hospitalizations had a significantly worse median overall survival compared to those who did not(8.7 mo vs 14.6 mo, P < 0.001).CONCLUSION Gastric PC carries a grim prognosis with a clinical course fraught with disease-related complications which may attenuate any survival benefit which palliative systemic chemotherapy may have to offer. As such, investigational use of regional therapies is warranted and required validation in patients with isolated PC to maximize their survival outcomes in the long run. | Hwee Leong Tan Claramae Shulyn Chia Grace Hwei Ching Tan Su Pin Choo David Wai-Meng Tai Clarinda Wei Ling Chua Matthew Chau Hsien Ng Khee Chee Soo Melissa Ching Ching Teo | 2017 | World Journal of Gastrointestinal Oncology2017，9，3： | 6 |
