| 1 | Mammalian WTAP is a regulatory subunit of the RNA N6-methyladenosine methyltransferase显示文摘包含 methyltransferase 建筑群的象 3 一样的 methyltransferase (METTL3 ) 催化 N6-methyladenosine (m6A ) 形成,一个新奇 epitranscriptomic 标记;然而,这建筑群的性质仍然保持大部分未知。这里,我们报导人的 m6A methyltransferase 建筑群, Wilm 的肿瘤 1 伙伴蛋白质(WTAP ) 和象 14 一样的 methyltransferase (METTL14 ) 的二个新部件。WTAP 与 METTL3 和 METTL14 交往,并且为他们的本地化被要求进在 vivo 与处理因素的 pre-mRNA 并且为 m6A methyltransferase 的催化活动充实的原子点缀。RNA 的多数在 vivo 由 WTAP 和 METTL3 跳了代表包含一致 m6A 主题的 mRNAs。当 WTAP 不在时, METTL3 的 RNA 有约束力的能力强烈被减少,建议 WTAP 可以工作调整到 mRNA 目标的 m6A methyltransferase 建筑群的招募。而且,在有 photoactivatable-ribonucleoside-enhanced crosslinking 和 immunoprecipitation (同等片断) 的联合的 transcriptomic 分析说明那 WTAP 和 METTL3 调整涉及抄写并且 RNA 处理的基因拼接的表示和选择。在 zebrafish 胚胎的调停 Morpholino 的击倒的指向 WTAP 或 METTL3 引起了织物区别缺点并且增加了 apoptosis。这些调查结果提供 WTAP 可以在 m6A methyltransferase 建筑群作为一个规章的子单元工作并且在 RNA 的 epitranscriptomic 规定起一个关键作用的充分证据新陈代谢。 | Xiao-Li Ping Bao-Fa Sun Lu Wang Wen Xiao Xin Yang Wen-Jia Wang Samir Adhikari Yue Shi Ying Lv Yu-Sheng Chen Xu Zhao Ang Li Ying Yang Ujwal Dahal Xiao-Min Lou Xi Liu Jun Huang Wei-Ping Yuan Xiao-Fan Zhu Tao Cheng Yong-Liang Zhao Xinquan Wang Jannie M Rendtlew Danielsen Feng Liu Yun-Gui Yang | 2014 | Cell Research2014，24，2： | 244 |
| 2 | Preoperative biliary drainage in patients with hilar cholangiocarcinoma undergoing major hepatectomy显示文摘AIM:To investigate the effect of preoperative biliary drainage(PBD)in jaundiced patients with hilar cholangiocarcinoma(HCCA)undergoing major liver resections.METHODS:An observational study was carried out by reviewing a prospectively maintained database of HCCA patients who underwent major liver resection for curative therapy from January 2002 to December 2012.Patients were divided into two groups based on whether PBD was performed:a drained group and an undrained group.Patient baseline characteristics,preoperative factors,perioperative and short-term postoperative outcomes were compared between the two groups.Risk factors for postoperative complications were also analyzed by logistic regression test with calculating OR and 95%CI.RESULTS:In total,78 jaundiced patients with HCCA underwent major liver resection:32 had PBD prior to operation while 46 did not have PBD.The two groups were comparable with respect to age,sex,body mass index and co-morbidities.Furthermore,there was no significant difference in the total bilirubin(TBIL)levels between the drained group and the undrained group at admission(294.2±135.7 vs 254.0±63.5,P=0.126).PBD significantly improved liver function,reducing not only the bilirubin levels but also other liver enzymes.The preoperative TBIL level was significantly lower in the drained group as compared to the undrained group(108.1±60.6 vs 265.7±69.1,P=0.000).The rate of overall postoperative complications(53.1%vs 58.7%,P=0.626),reoperation rate(6.3%vs 6.5%,P=1.000),postoperative hospital stay(16.5 vs 15.0,P=0.221)and mortality(9.4%vs 4.3%,P=0.673)were similar between the two groups.In addition,there was no significant difference in infectious complications(40.6%vs 23.9%,P=0.116)and noninfectious complications(31.3%vs 47.8%,P=0.143)between the two groups.Univariate and multivariate analyses revealed that preoperative TBIL>170μmol/L(OR=13.690,95%CI:1.275-147.028,P=0.031),Bismuth-Corlette classification(OR=0.013,95%CI:0.001-0.166,P=0.001)and extended liver resection(OR=14.010,95%CI:1.130-173.646,P=0.040)were independent risk factors for postoperative complications.CONCLUSION:Overall postoperative morbidity and mortality rates after major liver resection are not improved by PBD in HCCA patients with jaundice.Preoperative TBIL>170μmol/L,Bismuth-Corlette classification and extended liver resection are independent risk factors linked to postoperative complications. | Jun-Jie Xiong Quentin M Nunes Wei Huang Samir Pathak Ai-Lin Wei Chun-Lu Tan Xu-Bao Liu | 2013 | World Journal of Gastroenterology2013，19，46： | 33 |
| 3 | Alcohol,inflammation,and gut-liver-brain interactions in tissue damage and disease development显示文摘Chronic inflammation is often associated with alcoholrelated medical conditions. The key inducer of such inflammation, and also the best understood, is gut microflora-derived lipopolysaccharide (LPS). Alcohol can significantly increase the translocation of LPS from the gut. In healthy individuals, the adverse effects of LPS are kept in check by the actions and interactions of multiple organs. The liver plays a central role in detoxifying LPS and producing a balanced cytokine milieu. The central nervous system contributes to anti-inflammatory regulation through neuroimmunoendocrine actions. Chronic alcohol use impairs not only gut and liver functions, but also multi-organ interactions, leading to persistent systemic inflammation and ultimately, to organ damage. The study of these interactions may provide potential new targets for therapeutic intervention. | H Joe Wang Samir Zakhari M Katherine Jung | 2010 | World Journal of Gastroenterology2010，16，11： | 26 |
| 4 | Simulation in endoscopy:Practical educational strategies to improve learning显示文摘In gastrointestinal endoscopy, simulation-based training can help endoscopists acquire new skills and accelerate the learning curve. Simulation creates an ideal environment for trainees, where they can practice specific skills, perform cases at their own pace, and make mistakes with no risk to patients. Educators also benefit from the use of simulators, as they can structure training according to learner needs and focus solely on the trainee. Not all simulation-based training,however, is effective. To maximize benefits from this instructional modality,educators must be conscious of learners' needs, the potential benefits of training,and associated costs. Simulation should be integrated into training in a manner that is grounded in educational theory and empirical data. In this review, we focus on four best practices in simulation-based education: deliberate practice with mastery learning, feedback and debriefing, contextual learning, and innovative educational strategies. For each topic, we provide definitions,supporting evidence, and practical tips for implementation. | Rishad Khan Michael A Scaffidi Samir C Grover Nikko Gimpaya Catharine M Walsh | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，3： | 3 |

| 6 | Animal models of ex vivo lung perfusion as a platform for transplantation research显示文摘Ex vivo lung perfusion(EVLP) is a powerful experimental model for isolated lung research. EVLP allows for the lungs to be manipulated and characterized in an external environment so that the effect of specific ventilation/perfusion variables can be studied independent of other confounding physiologic contributions. At the same time,EVLP allows for normal organ level function and real-time monitoring of pulmonary physiology and mechanics. As a result,this technique provides uniqueadvantages over in vivo and in vitro models. Small and large animal models of EVLP have been developed and each of these models has their strengths and weaknesses. In this manuscript,we provide insight into the relative strengths of each model and describe how the development of advanced EVLP protocols is leading to a novel experimental platform that can be used to answer critical questions in pulmonary physiology and transplant medicine. | Kevin Nelson Christopher Bobba Samir Ghadiali Don Hayes Jr Sylvester M Black Bryan A Whitson | 2014 | World Journal of Experimental Medicine2014，4，2： | 2 |
