Overweight or obesity has become a serious public health problem in the world, scientists are concentrating their efforts on exploring novel ways to treat obesity. Nowadays, the availabilities of bariatric surgery and pharmacotherapy have enhanced obesity treatment, but it should has support from diet, physical exercise and lifestyle modification, especially the functional food. Resistant starch, an indigestible starch, has been studied for years for its beneficial effects on regulating blood glucose level and lipid metabolism. The aim of this review is to summarize the effect of resistant starch on weight loss and the possible mechanisms. According to numerous previous studies it could be concluded that resistant starch can reduce fat accumulation, enhance insulin sensitivity, regulate blood glucose level and lipid metabolism. Recent investigations have focused on the possible associations between resistant starch and incretins as well as gut microbiota. Resistant starch seems to be a promising dietary fiber for the prevention or treatment of obesity and its related diseases.

While constipation is a common symptom in Korea, there are no existing treatment guidelines. Although constipation may occur as a result of organic cause, there is no obstructive mucosal or structural cause in the vast majority of patients with constipation. The present paper deals with only the management of functional constipation: lifestyle changes; bulking agents and stool softeners; osmotic agents; stimulant laxatives; prokinetics; biofeedback and surgical treatments. Exercise and dietary fiber are helpful in some patients with constipation. Laxatives including bulking agents, stool softeners, osmotic agents, and stimulant laxatives have been found to be more effective than placebo at relieving symptoms of constipation. New enterokinetic agents that affect peristalsis through selective interaction with 5-hydroxytryptamine-4 receptors can be effective in patients with constipation who cannot get adequate relief from current laxatives. Biofeedback can relieve symptoms in selected patients with pelvic floor dyssynergia. Surgical treatments can be helpful in some patients with refractory constipation.

beta-Glucan is a polysaccharide in the form of fiber and the main element of fiber in grains such as barley, oats, yeast and mushrooms. Many studies have examined the efficacy of beta-Glucan in terms of the lipid lowering effects, blood sugar reduction, weight reduction, immune modulator, and anticarcinogenic effect. However, there is no comprehensive review article on the biomedical issues regarding beta-Glucan. The authors searched for systematic reviews and clinical experiments for each relevant topic and reviewed the biomedical effects of beta-Glucan, for the purpose of developing research strategies for the future.

Traditional symptom-based therapies of irritable bowel syndrome (IBS) are directed at the relief of individual IBS symptoms, but they are often of limited efficacy in addressing the entire symptom complex. Combinations of drugs to target bothersome symptoms are suggested as the first-line pharmacologic treatment. Increasing knowledge of the pathophysiology and molecular mechanisms of IBS has resulted in the development of several new therapeutic approaches. Thirteen consensus statements for the treatment of IBS were developed using the modified Delphi approach. Exclusion diets have modest efficacy in improving symptoms in some IBS patients. Symptom-based therapies with dietary fiber, bulking agents, laxatives, antispasmodics and laxatives are effective in the improvement of some individual symptoms, e.g. dietary fiber and bulking agents for constipation, laxatives for constipation, antispasmodics for abdominal pain and discomfort, antidiarrheals for diarrhea. 5HT3 receptor antagonists and 5HT4 receptor agonists are effective in the relief of global IBS symptoms and individual symptoms such as abdominal pain and abnormal bowel habits. A short term course of nonabsorbable antibiotics may improve global IBS symptoms, particularly in patients with diarrhea- predominant IBS. Some probiotics appear to have the potential benefit in improving global IBS symptoms. Selective C-2 chloride channel activator is more effective than placebo at relieving global IBS symptoms in patients with constipation-predominant IBS. Both tricyclic antidepressants and selective serotonin reuptake inhibitors are equally effective in relieving global IBS symptoms, and have some benefits in treating abdominal pain. Certain types of psychologic therapy may be effective in improving global symptoms in some IBS patients. Further studies are strongly needed to develop better treatment strategies for Korean patients with IBS.

Crohn's disease is characterized by chronic transmural inflammation of the bowel and is associated with serious complications, such as bowel strictures, abscesses, fistula formation, and perforation. As neither medical nor surgical therapy provides a cure for Crohn's disease, the primary goals of therapy are to induce and maintain remission and prevent complications. As a biologic agent, infliximab, a monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizing Crohn's disease that does not respond to other medical therapies or surgery. Infliximab has proven to be very effective for inducing and maintaining remission in Crohn's disease; however, infliximab treatment has several potential complications. Here, we report a case of free perforation following a therapeutic response after an initial dose of infliximab for Crohn's disease. This is the first case report describing a free perforation in a Crohn's disease patient after an initial dose of infliximab.

OBJECTIVETo investigate the influence of early enteral nutrition with synbiotics on the plasma endotoxin level, the nutritional state, the inflammatory response and the incidence of infectious complications in severely burned patients.
METHODSRandomized double blind and control method was employed im the study. Forty severely burned patients were randomly divided into A and B groups with 20 in each group. The patients in group A received early enteral nutrition with synbiotics including four kinds of lactic acid bacteria and four kinds of fibers, while those in group B received early enteral nutrition with synbiotics including only four kinds of fibers. The patients with 80% to 280% coefficient unit burned surface(UBS) were further divided into A1 (n = 10) and B1 (n = 11) groups. The plasma endotoxin level in group A and B was determined dynamically on the 1st, 3rd, 7th, 10th, 14th, and 21st postburn days (PBD), and its abnormal rate in both groups was statistically analyzed in correlation with the normal endotoxin level. meanwhile, the mortality, the incidence of infectious complications and the blood bacterial culture results were compared between the two groups. The plasma levels of IL-1, IL-6 and prognostic inflammatory nutrition index (PINI) were also determined at the above time points.
RESULTSThe plasma endotoxin level in group A (37.9 +/- 5.4) ng/L was evidently lower than that in group B (59.1 +/- 7.9) ng/L (P < 0.05) on 10 PBD. The abnormal rate of plasma endotoxin in group A (36.7%) was evidently lower than that (49.2%) in group B (P < 0.05). Blood culture was positive in 3 patients in group A, and 5 in group B. There was no obvious difference in the incidence of infectious complication between the two groups. Two patients died in group A and 1 group B. There was no obvious difference in plasma IL-1 level between A1 and B1 groups at different time points. The plasma IL-6 level in A1 group in 10th and 14th PBD was evidently lower than that in B1 group (P < 0.05). The PINI in A1 group on the 10 PBD was remarkably lower than that in B1 group.
CONCLUSIONEarly enteral nutrition with synbiotics was helpful in decreasing inflammatory stress response and lowering the plasma endotoxin level. Enteral supplementation of synbiotics might be beneficial to the controlling of burn infection.

Constipation is a digestive symptom that is frequently seen in clinical practice. Its prevalence has been reported to be 2% to 20%, depending on geographical region. Despite the rapid development of medical science, systematic studies on constipation have been rarely conducted in Korea. Recently, guidelines on the diagnosis and treatment of functional gastrointestinal disorders, including constipation, were proposed by The Korean Society of Neurogastroenterology and Motility. These guidelines are expected to reflect the current situation regarding treatment of constipation in Korea. In this paper, practical constipation treatment methods that are in current use will be reviewed with reference to these recent guidelines.

OBJECTIVETo explore the factors affected insulin sensitivity index (ISI) and the effects of superior fiber complex (SFC) on ISI and blood lipids in non-insulin dependent diabetes mellitus (NIDDM) rats.
METHODSTwenty-six male Wistar rats were injected with low dose of streptozotocin and fed a diet with high calorie and high fat for ten weeks and glucose tolerance (GTT), fasting insulin (FINS), total cholesterol (TC) and triglyceride (TG) were measured while area under curve (AUC) and insulin sensitivity index (ISI) were also calculated. The results were compared with those from 7 normal control rats. Multi-factor regression analysis was used to analyze those factors affected ISI. In the same experiment, 13 rats with diabetes mellitus were treated with Superior Fiber Complex (SFC) for 8 weeks and the results were compared with the pre-treated data.
RESULTSCompared with the control group, AUC in the diabetic group was larger, and FINS, TC and TG were higher; but ISI was lower. Therefore, The TG and AUC was the major factor affected ISI. TC and TG were lowered and AUC was reduced and ISI increased.
CONCLUSIONHigh TG and impaired glucose tolerance (IGT) are main risk factors of ISI in the rat model, and SFC could increase ISI, decrease high blood lipids and prevent IGT.

Dietary fiber improves hyperglycemia in patients with type 2 diabetes through its physicochemical properties and possible modulation of gut hormone secretion, such as glucagon-like peptide 1 (GLP-1). We assessed the effect of dietary fiber-enriched cereal flakes (DC) on postprandial hyperglycemia and gut hormone secretion in patients with type 2 diabetes. Thirteen participants ate isocaloric meals based on either DC or conventional cereal flakes (CC) in a crossover design. DC or CC was provided for dinner, night snack on day 1 and breakfast on day 2, followed by a high-fat lunch. On day 2, the levels of plasma glucose, GLP-1, glucose-dependent insulinotropic polypeptide (GIP), and insulin were measured. Compared to CC, DC intake exhibited a lower post-breakfast 2-hours glucose level (198.5±12.8 vs. 245.9±15.2 mg/dL, P<0.05) and a lower incremental peak of glucose from baseline (101.8±9.1 vs. 140.3±14.3 mg/dL, P<0.001). The incremental area under the curve (iAUC) of glucose after breakfast was lower with DC than with CC (P<0.001). However, there were no differences in the plasma insulin, glucagon, GLP-1, and GIP levels. In conclusion, acute administration of DC attenuates postprandial hyperglycemia without any significant change in the representative glucose-regulating hormones in patients with type 2 diabetes (ClinicalTrials.gov. NCT 01997281).
