Abstract
Pancreatic diseases such as pancreatitis, type 1 diabetes and pancreatic cancer impose substantial health-care costs and contribute to marked morbidity and mortality. Recent studies have suggested a link between gut microbiota dysbiosis and pancreatic diseases; however, the potential roles and mechanisms of action of gut microbiota in pancreatic diseases remain to be fully elucidated. In this review, we summarize the evidence that supports relationship between alterations of gut microbiota and development of pancreatic diseases, and discuss the potential molecular mechanisms of gut microbiota dysbiosis in the pathogenesis of pancreatic diseases. We also propose current strategies toward gut microbiota to advance a developing research field that has clinical potential to reduce the cost of pancreatic diseases.

Abstract
INTRODUCTION Acute pancreatitis (AP) is an inflammatory disease with no specific treatment. Mitochondrial injury followed by ATP depletion in both acinar and ductal cells is a recently discovered early event in its pathogenesis. Importantly, preclinical research has shown that intracellular ATP delivery restores the physiological function of the cells and protects from cell injury, suggesting that restoration of energy levels in the pancreas is therapeutically beneficial. Despite several high quality experimental observations in this area, no randomised trials have been conducted to date to address the requirements for energy intake in the early phase of AP. METHODS/DESIGN This is a randomised controlled two-arm double-blind multicentre trial. Patients with AP will be randomly assigned to groups A (30 kcal/kg/day energy administration starting within 24 hours of hospital admission) or B (low energy administration during the first 72 hours of hospital admission). Energy will be delivered by nasoenteric tube feeding with additional intravenous glucose supplementation or total parenteral nutrition if necessary. A combination of multiorgan failure for more than 48 hours and mortality is defined as the primary endpoint, whereas several secondary endpoints such as length of hospitalisation or pain will be determined to elucidate more detailed differences between the groups. The general feasibility, safety and quality checks required for high quality evidence will be adhered to. ETHICS AND DISSEMINATION The study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (55961-2/2016/EKU). This study will provide evidence as to whether early high energy nutritional support is beneficial in the clinical management of AP. The results of this trial will be published in an open access way and disseminated among medical doctors. TRIAL REGISTRATION The trial has been registered at the ISRCTN (ISRTCN 63827758).

Abstract
The present study applied fast-track surgery (FTS) concepts and exclusive enteral nutrition (EEN) to a rat model of heterotopic intestinal transplantation (HIT). A total of 96 pairs of Sprague-Dawley rats were randomly distributed into three groups, as follows: i) The conventional group (group 1); ii) the FTS group (group 2); and iii) the FTS with EEN group (EEN group). FTS alterations to the HIT protocol were as follows: i) The use of sevoflurane as an anesthetic; ii) alterations to the order of the procedure and iii) a modified suturing technique. In addition, the EEN group rats underwent an early EEN gavage. The operation time, success rate, recovery state and morphological characteristics of the grafts were compared among the groups. The average operative time was significantly decreased in the group 2 and EEN group rats (137.44±16.03 and 139.67±15.25 min, respectively), as compared with the group 1 rats (169.36±13.72 min; P<0.05). In addition, the percentage of rats surviving >14 days was significantly increased in the group 2 (87.5%) and EEN group (90.6%) rats, as compared with the group 1 rats (68.7%; P<0.05). Furthermore, the villi of graft in EEN group appeared longer, and exhibited narrower interspaces. The ischemia-reperfusion injury and mononuclear cell infiltration were attenuated at postoperative day 7. The results of the present study suggested that the application of FTS concepts and EEN gavage to HIT may accelerate recovery and ameliorate graft damage following surgery.

Abstract
OBJECTIVE To study the effect of enteral nutrition (EN) on dextran sulfate sodium (DSS)-induced colitis in rats. METHODS Eighty-four Sprague-Dawley rats were divided into 7 groups (12 rats in each group). The blank control group was given ordinary laboratory feed and drinking water. The experimental groups received 5% DSS as drinking water for 7 days. Of the experimental groups, the model control group received ordinary laboratory feed, protein based enteral nutrition (PEN) was fed in the PEN group, while other groups received ordinary laboratory feed plus 5-aminosalicylic acid (5-ASA), methyl-prednisolone, Lactobacillus or glutamine, respectively. On the 8th day, all the rats were sacrificed. Inflammatory scores were assessed from colonic mucosa. Blood culture from inferior vena cava, fecal culture and secretary immunoglobulin-A (S-IgA) levels from colonic contents were determined. RESULTS Colon inflammatory scores of Lactobacillus, PEN, glutamine and drug-treated groups were lower than that of the model control group (P < 0.01). The ratios of bacteria translocation in the EN (PEN, Lactobacillus and glutamine) groups were lower than that in the model control group (P < 0.0083). Fecal Lactobacilli in the Lactobacillus and glutamine groups were higher than that in the model control group (P < 0.05). S-IgA levels in colonic contents of the PEN and 5-ASA group were lower than that in the model control group (P < 0.05). CONCLUSIONS EN is an effective therapy for treating DDS-induced colitis. EN could alleviate damage, promote the repair of colonic epithelial cells and inhibit bacterial translocation. Lactobacillus and glutamine could also increase the Lactobacilli in colon.

Abstract
The patients with acute pancreatitis are at risk to develop different complications from ongoing pancreatic inflammation. Often, there is no correlation between the degree of structural damage to pancreas and clinical manifestation of the disease. The effectiveness of any treatment is related to the ability to predict severity accurately, but there is no ideal predictive system or biochemical marker. Severity assessment is indispensable to the selection of proper initial treatment in the management of acute pancreatitis. The use of multiparametric criteria and the evaluation of severity index permit us to select high-risk patients. Furthermore, contrast-enhanced computed tomographic scanning and contrast-enhanced MRI play an important role in severity assessment. The adoption of multiparametric criteria proposed together with morphological evaluation consents the formulation of a discreetly reliable prognosis on the evolution of the disease a few days from onset.

Abstract
OBJECTIVE Previously, we observed decreased histopathological severity of acute necrotizing pancreatitis (ANP) by parenteral nutrition with n-3 fatty acids. Thus, we now sequentially analyzed the impact of n-3 fatty acids on prostaglandin and leukotriene synthesis in ANP. METHODS One hundred ninety-eight Sprague-Dawley rats (11 groups, n = 18) underwent intraductal glycodesoxycholat instillation and 6-hour cerulein infusion. Afterward, saline was infused in groups 2, 4, 6, 8, and 10, whereas groups 3, 5, 7, 9, and 11 received infusion rich in n-3 fatty acids (Omegaven, Fresenius Kabi, Bad Homburg, Germany). Animals were killed after 6 (group 1), 10 (groups 2 and 3), 14 (groups 4 and 5), 18 (groups 6 and 7), 22 (groups 8 and 9), and 26 hours (groups 10 and 11). The pancreas was histopathologically examined, and the pancreatic eicosanoid metabolism (prostaglandin E2, prostaglandin F1alpha [PGF1alpha], and leukotrienes) and lipid peroxidation (thiobarbituric acid-reactive substance, superoxide dismutase, and glutathione peroxidase) were analyzed. RESULTS Between the 14th and 26th hours, histopathologic scores (edema, inflammation, bleeding, and necrosis) were reduced in the n-3 fatty acid group compared with the corresponding saline group. Pancreatic prostaglandin E2 and PGF1alpha were decreased between the 10th and 18th hour by n-3 fatty acids; PGF1alpha was reduced after 26 hours compared with the corresponding saline group. Lipid peroxidation was decreased by n-3 fatty acids after 14 hours (thiobarbituric acid-reactive substance); however, there was no difference concerning lipid peroxidation protective enzymes (glutathione peroxidase and superoxide dismutase). CONCLUSIONS Parenteral therapy with n-3 fatty acids decreased histopathologic severity in ANP by early inhibition of prostaglandin (E2 and F1alpha) synthesis and reduction of lipid peroxidation.

Abstract
The advent of total parenteral nutrition in the late 1960s meant that no situation remained in which a patient could not be fed. Unfortunately, total parenteral nutrition was complicated by serious infective and metabolic side effects that undermined the beneficial effects of nutrient repletion. Consequently, creative ways of restoring upper gut function were designed, based on semielemental diets and novel feeding tube systems. The employment of specific protocols and acceptance of increased gastric residual volumes has allowed most patients in intensive care to be fed safely and early by nasogastric tube. However, nasogastric feeding is unsuitable for patients with severely compromised gastric emptying owing to partial obstruction or ileus. Such patients require postpyloric tube placement with simultaneous gastric decompression via double-lumen nasogastric decompression and jejunal feeding tubes. These tubes can be placed endoscopically 40-60 cm past the ligament of Treitz to enable feeding without pancreatic stimulation. In patients whose disorders last more than 4 weeks, tubes should be repositioned percutaneously, by endoscopic, open or laparoscopic surgery. Together, the advances in enteral access have improved patients' outcomes and led to a 70-90% reduction in the demand for total parenteral nutrition.
