| 1 | 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 |
| 2 | 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 |
| 3 | Gastroenterologist perceptions of faecal microbiota transplantation显示文摘AIM: To explore gastroenterologist perceptions towards and experience with faecal microbiota transplantation(FMT).METHODS: A questionnaire survey consisting of 17 questions was created to assess gastroenterologists' attitude towards and experience with FMT. This was anonymously distributed in hard copy format amongst attendees at gastroenterology meetings in Australia between October 2013 and April 2014. Basic descriptive statistical analyses were performed.RESULTS: Fifty-two clinicians participated. Twenty one percent had previously referred patients for FMT,8% more than once. Ninety percent would refer patients with Clostridium difficile infection(CDI) for FMT if easily available,37% for ulcerative colitis,13% for Crohn's disease and 6% for irritable bowel syndrome. Six percent would not refer any indication,including recurrent CDI. Eighty-six percent would enroll patients in FMT clinical trials. Thirty-seven percent considered the optimal mode of FMT administration transcolonoscopic,17% nasoduodenal,13% enema and 8% oral capsule. The greatest concerns regarding FMT were: 42% lack of evidence,12% infection risk,10% non infectious adverse effects/lack of safety data,10% aesthetic,10% lack of efficacy,4% disease exacerbation,and 2% inappropriate use; 6% had no concerns. Seventy seven percent believed there is a lack of accessibility while 52% had an interest in learning how to provide FMT. Only 6% offered FMT at their institution.CONCLUSION: Despite general enthusiasm,most gastroenterologists have limited experience with,or access to,FMT. The greatest concerns were lack of supportive evidence and safety issues. However a significant proportion would refer indications other than CDI for FMT despite insufficient evidence. These data provide guidance on where education and training are required. | Sudarshan Paramsothy Alissa J Walsh Thomas Borody Douglas Samuel Johan van den Bogaerde Rupert WL Leong Susan Connor Watson Ng Hazel M Mitchell Nadeem O Kaakoush Michael A Kamm | 2015 | World Journal of Gastroenterology2015，21，38： | 5 |
| 4 | Rho/Rock signal transduction pathway is required for MSC tenogenic differentiation显示文摘Mesenchymal stem cell(MSC)-based treatments have shown promise for improving tendon healing and repair.MSCs have the potential to differentiate into multiple lineages in response to select chemical and physical stimuli, including into tenocytes. Cell elongation and cytoskeletal tension have been shown to be instrumental to the process of MSC differentiation. Previous studies have shown that inhibition of stress fiber formation leads MSCs to default toward an adipogenic lineage, which suggests that stress fibers are required for MSCs to sense the environmental factors that can induce differentiation into tenocytes. As the Rho/ROCK signal transduction pathway plays a critical role in both stress fiber formation and in cell sensation, we examined whether the activation of this pathway was required when inducing MSC tendon differentiation using rope-like silk scaffolds. To accomplish this, we employed a loss-of-function approach by knocking out ROCK,actin and myosin(two other components of the pathway) using the specific inhibitors Y-27632, Latrunculin A and blebbistatin, respectively. We demonstrated that independently disrupting the cytoskeleton and the Rho/ROCK pathway abolished the expression of tendon differentiation markers and led to a loss of spindle morphology. Together, these studies suggest that the tension that is generated by MSC elongation is essential for MSC teno-differentiation and that the Rho/ROCK pathway is a critical mediator of tendon differentiation on rope-like silk scaffolds. | Edward Maharam Miguel Yaport Nathaniel L Villanueva Takintope Akinyibi Damien Laudier Zhiyong He Daniel J Leong Hui B Sun | 2015 | Bone Research2015，3，3： | 4 |
| 5 | Indications and surgical options for small bowel, large bowel and perianal Crohn's disease显示文摘Despite advancements in medical therapy of Crohn's disease(CD), majority of patients with CD will eventually require surgical intervention, with at least a third of patients requiring multiple surgeries. It is important to understand the role and timing of surgery, with the goals of therapy to reduce the need for surgery without increasing the odds of emergency surgery and its associated morbidity, as well as to limit surgical recurrence and avoid intestinal failure. The profile of CD patients requiring surgical intervention has changed over the decades with improvements in medical therapy with immunomodulators and biological agents. The most common indication for surgery is obstruction from stricturing disease, followed by abscesses and fistulae. The risk of gastrointestinal bleeding in CD is high but the likelihood of needing surgery for bleeding is low. Most major gastrointestinal bleeding episodes resolve spontaneously, albeit the risk of re-bleeding is high. The risk of colorectal cancer associated with CD is low. While current surgical guidelines recommend a total proctocolectomy for colorectal cancer associated with CD, subtotal colectomy or segmental colectomy with endoscopic surveillance may be a reasonable option. Approximately 20%-40% of CD patients will need perianal surgery during their lifetime. This review assesses the practice parameters and guidelines in the surgical management of CD, with a focus on the indications for surgery in CD(and when not to operate), and a critical evaluation of the timing and surgical options available to improve outcomes and reduce recurrence rates. | James WT Toh Peter Stewart Matthew JFX Rickard Rupert Leong Nelson Wang Christopher J Young | 2016 | World Journal of Gastroenterology2016，22，40： | 2 |
