| 4 | Visceral hypersensitivity and electromechanical dysfunction as therapeutic targets in pediatric functional dyspepsia显示文摘Functional gastrointestinal disorders(FGID) are common clinical syndromes diagnosed in the absence of biochemical,structural,or metabolic abnormalities. They account for significant morbidity and health care expenditures and are identifiable across variable age,geography,and culture. Etiology of abdominal pain associated FGIDs,including functional dyspepsia(FD),remains incompletely understood,but growing evidence implicates the importance of visceral hypersensitivity and electromechanical dysfunction. This manuscript explores data supporting the role of visceral hypersensitivity and electromechanical dysfunction in FD,with focus on pediatric data when available,and provides a summary of potential therapeutic targets. | John M Rosen Jose T Cocjin Jennifer V Schurman Jennifer M Colombo Craig A Friesen | 2014 | World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,3: | 16 |
| 5 | Effect of Welding Processes and Consumables on Tensile and Impact Properties of High Strength Quenched and Tempered Steel Joints显示文摘Quenched and tempered steels are prone to hydrogen induced cracking in the heat affected zone after welding.The use of austenitic stainless steel consumables to weld the above steel was the only available remedy because of higher solubility for hydrogen in austenitic phase.In this investigation,an attempt was made to determine a suitable consumable to replace expensive austenitic consumables.Two different consumables,namely,austenitic stainless steel and low hydrogen ferritic steel,were used to fabricate the joints by shielded metal arc welding(SMAW)and flux cored arc welding(FCAW)processes.The joints fabricated by using low hydrogen ferritic steel consumables showed superior transverse tensile properties,whereas joints fabricated by using austenitic stainless steel consumables exhibited better impact toughness,irrespective of the welding process used.The SMAW joints exhibited superior mechanical and impact properties,irrespective of the consumables used,than their FCAW counterparts. | G Magudeeswaran V Balasubramanian G Madhusudhan Reddy T S Balasubramanian | 2008 | Journal of Iron and Steel Research(International)2008,15,6: | 16 |
| 6 | Effect of Helicobacter pylori on gastric epithelial cells显示文摘The gastrointestinal epithelium has cells with features that make them a powerful line of defense in innate mucosal immunity. Features that allow gastrointestinal epithelial cells to contribute in innate defense include cell barrier integrity, cell turnover, autophagy, and innate immune responses. Helicobacter pylori(H. pylori) is a spiral shape gram negative bacterium that selectively colonizes the gastric epithelium of more than half of the world's population. The infection invariably becomes persistent due to highly specialized mechanisms that facilitate H. pylori 's avoidance of this initial line of host defense as well as adaptive immune mechanisms. The host response is thus unsuccessful in clearing the infection and as a result becomes established as a persistent infection promoting chronic inflammation. In some individuals the associated inflammation contributes to ulcerogenesis or neoplasia. H. pylori has an array of different strategies to interact intimately with epithelial cells and manipulate their cellular processes and functions. Among the multiple aspects that H. pylori affects in gastric epithelial cells are their distribution of epithelial junctions, DNA damage, apoptosis, proliferation, stimulation of cytokine production, and cell transformation. Some of these processes are initiated as a result of the activation of signaling mechanisms activated on binding of H. pylori to cell surface receptors or via soluble virulence factors that gain access to the epithelium. The multiple responses by the epithelium to the infection contribute to pathogenesis associated with H. pylori. | Shatha Alzahrani Taslima T Lina Jazmin Gonzalez Irina V Pinchuk Ellen J Beswick Victor E Reyes | 2014 | World Journal of Gastroenterology2014,20,36: | 15 |

| 11 | 嗜水气单胞菌ZN1攻击鳗鲡后的组织病理观察显示文摘采用1/2半致死剂量的嗜水气单胞菌ZN1对鳗鲡进行腹腔注射,在第0 d、1 d、3 d、7 d、14 d、21 d采集鳗鲡肝、脾、肾、肠,观察鳗鲡经嗜水气单胞菌活菌攻击后各脏器的组织病理变化及脏器的损伤修复情况。结果显示,嗜水气单胞菌活菌ZN1攻击后鳗鲡肝、肾、脾、肠等组织细胞均出现程度不同的病变,且持续时间长达14 d以上,同时血液中的血栓细胞急剧减少,甚至全部消失。上述结果表明嗜水气单胞菌攻击后可引发鳗鲡各脏器发生明显的病理变化,并提示在病原菌攻击引起鳗鲡血栓细胞的减少并恢复缓慢可能是嗜水气单胞菌导致宿主产生败血症状的重要病理机制。 | 宋铁英 龚晖 Khomyakova T I 杨金先 李艳虹 Makarova O V 林天龙 | 2008 | 福建农业学报2008,23,1: | 10 |
| 12 | Treatment strategies for colorectal carcinoma with synchronous liver metastases: Which way to go?显示文摘AIM: To offer an up-to-date review of all availabletreatment strategies for patients with synchronous colorectal liver metastases(CLM).METHODS: A comprehensive literature search was performed to identify articles related to the management of patients with synchronous CLM. A search of the electronic databases PubMed, MEDLINE, and Google Scholar was conducted in September 2014.The following search terms were used: synchronous colorectal liver metastases, surgery, stage Ⅳ colorectal cancer, liver-first approach, and up-front hepatectomy.These terms were employed in various combinations to maximize the search. Only articles written in English were included. Particular attention was devoted to studies and review articles that were published within the last six years(2009-2014). Additional searches of the cited references from primary articles were performed to further improve the review. The full texts of all relevant articles were accessed by two independent reviewers.RESULTS: Poor long-term outcomes of patients with synchronous CLM managed by a traditional treatment strategy have led to questions about the timing and sequence of possible therapeutic interventions. Thus,alternative paradigms called reverse strategies have been proposed. Presently, there are four treatment strategies available:(1) primary first approach(or traditional approach) comprises resection of the primary colorectal tumor followed by chemotherapy;subsequent liver resection is performed 3-6 mo after colorectal resection(provided that CLM are still resectable);(2) simultaneous resection of the primary colorectal tumor and CLM during a single operation presents intriguing options for a highly select group of patients, which can be associated with significant postoperative morbidity;(3) liver-first(or chemotherapy-first) approach comprises preoperative chemotherapy(3-6 cycles) followed by liver resection,adjuvant chemotherapy, and resection of the primary colorectal tumor(it is best suited for patients withasymptomatic primary tumors and initially unresectable or marginally resectable CLM); and(4) up-front hepatectomy(or 'true' liver-first approach) includes liver resection followed by adjuvant chemotherapy,colorectal resection, and adjuvant chemotherapy(strategy can be offered to patients with asymptomatic primary tumors and initially resectable CLM).CONCLUSION: None of the aforementioned strategies appears inferior. It is necessary to establish individual treatment plans in multidisciplinary team meetings through careful appraisal of all strategies. | Peter Ihnát Petr Vávra Pavel Zonca | 2015 | World Journal of Gastroenterology2015,21,22: | 10 |

| 16 | Alcohol dehydrogenase: A potential new marker for diagnosis of intestinal ischemia using rat as a model显示文摘AIM: Intestinal ischemia (Ii) is an abdominal emergency due to blockade of the superior mesenteric artery resulting in 60-100% mortality if diagnosed late. Changes in several biochemical parameters such as D (-)-lactate, Creatinine kinase isoenzymes and lactate dehydrogenase suggested for early diagnosis, lack specificity and sensitivity. Therefore a biochemical parameter with greater sensitivity needs to be identified.METHODS: Wistar male rats were randomly assigned into two groups; control sham operated (n = 24) and ischemic test (n = 24) group. Superior mesenteric arterial occlusion was performed in the ischemic test group for 1 h. Alcohol dehydrogenase (ADH) was estimated in blood from portal vein, right ventricle of heart, dorsal aorta (DA) and inferior vena cava (IVC). The Serum glutamic acid pyruvate transaminase (SGPT) was also estimated in blood from portal vein and right ventricle of heart.RESULTS: A significant increase (P<0.001) in the levels of ADH in both portal blood as well as heart blood of the test group (232.72±99.45 EU and 250.85±95.14 EU, respectively)as compared to the control group (46.39±21.69 EU and 65.38±30.55 EU, respectively) were observed. Similarly,increased levels of ADH were observed in blood samples withdrawn from DA and IVC in test animals (319.52±80.14EU and 363.90±120.68 EU, respectively) as compared to the control group (67.68±63.22 EU and 72.50±58.45 EU,respectively). However, in test animals there was significant increase in SGPT in portal blood (P = 0.054) without much increase in heart blood.CONCLUSION: Significant increase in the levels of ADH in portal and heart blood within 1 h of SMA occlusion without increase in SGPT in heart blood, suggests that the origin of ADH is from ischemic intestine and not from liver. Similarly, raised ADH levels were found in DA and IVC as well. IVC blood does represent peripheral blood sample. A raised level of ADH in test animals confirms it to be a potential marker in the early diagnosis of Ii. | Upendra R Gumaste Mukund M Joshi Devendra T Mourya Pradip V Barde Ghanshyam K Shrivastav Vikram S Ghole | 2005 | World Journal of Gastroenterology2005,11,6: | 9 |
| 17 | 高产奶量的母猪有更高的采食量和体动员显示文摘选择能哺育更大窝产仔数的超高产母猪以提高产仔数,但是综合考虑这些现代母猪产奶量、采食量和体动员相互之间联系的研究还很有限。试验旨在研究什么样的母猪产奶量高、窝产仔数多,不同胎次有何影响,以及哺乳期生产性能对下一胎繁殖性能有何影响。选择565头1~4胎母猪,试验期从产前7 d至断奶。产后第2天每窝仔猪统一调整为14头。产前7 d、产后第2天和断奶时测定母猪体重和背膘厚度。产后第2天和断奶时称取仔猪窝重。计算变量之间的皮尔森相关系数,建立回归模型。母猪的平均日采食量(6.1±1.1)kg,仔猪每天窝增重(2.92±0.53)kg,每头母猪的平均断奶仔猪数(13.0±1.1)头。总的来讲,与2~4胎母猪相比,1胎母猪平均日采食量和产奶量更低,下一胎总产仔数也下降,这可能是因为初产母猪相比经产母猪会动用更多体储。仔猪每窝平均日增重与母猪的采食量、窝产仔数和体重损失呈正相关。1~4胎母猪整个哺乳期日采食量每提高1 kg,仔猪窝日增重提高220~440 g,母猪哺乳期体重下降6.6~13.9 kg。但是每天平均产奶量提高1 kg,第4胎母猪哺乳期体重损失减少4.3~21.0 kg。下一胎总产仔数与上一胎产仔数呈正相关。总之,高采食量和高体动员是高产奶量的先决条件。母猪可能已经非常接近他们身体饲料摄取的生理极限,因此,未来的研究应着眼于优化哺乳期超高产母猪的饲粮能量和营养浓度以及初产母猪和经产母猪之间的区别。 | Strathe A V Bruun T S Hansen C F 李元凤 | 2017 | 养猪2017,,4: | 8 |

| 20 | Immune evasion strategies used by Helicobacter pylori显示文摘Helicobacter pylori(H. pylori) is perhaps the most ubiquitous and successful human pathogen, since it colonizes the stomach of more than half of humankind. Infection with this bacterium is commonly acquired during childhood. Once infected, people carry the bacteria for decades or even for life, if not treated. Persistent infection with this pathogen causes gastritis, peptic ulcer disease and is also strongly associated with the development of gastric cancer. Despite induction of innate and adaptive immune responses in the infected individual, the host is unable to clear the bacteria. One widely accepted hallmark of H. pylori is that it successfully and stealthily evades host defense mechanisms. Though the gastric mucosa is well protected against infection, H. pylori is able to reside under the mucus, attach to gastric epithelial cells and cause persistent infection by evading immune responses mediated by host. In this review, we discuss how H. pylori avoids innate and acquired immune response elements, uses gastric epithelial cells as mediators to manipulate host T cell responses and uses virulence factors to avoid adaptive immune responses by T cells to establish a persistent infection. We also discuss in this review how the genetic diversity of this pathogen helps for its survival. | Taslima T Lina Shatha Alzahrani Jazmin Gonzalez Irina V Pinchuk Ellen J Beswick Victor E Reyes | 2014 | World Journal of Gastroenterology2014,20,36: | 7 |
