尽管T2DM发病机制和防治研究不断深入,但全球T2DM患病率、发病率仍在攀升。随着T2DM病理生理机制研究更新,提高了对通过多种生物学途径有效控制血糖、保护胰岛β细胞、同时兼具减少心血管和肾脏等并发症风险药物的需求。源于自然界的天然药物常有多重药理作用且副作用小,与单纯化学合成药物相比,对糖尿病多病因治疗、保证治疗的安全性上,更具发展潜力。从中国传统中药材桑枝中提取分离的“有效组分”天然药物桑植总生物碱(SZ-A),具有独特的多重药理药效特点和更少的副作用。在胃肠道中,SZ-A可精准作用于双糖酶靶点,通过抑制糖苷酶的活性减缓葡萄糖的消化和吸收而快速控制餐后血糖,胃肠副作用比其他糖苷酶抑制剂类药物更小。本文基于充分的循证医学证据,深入阐释不同生物碱成分的协同机制,挖掘SZ-A用于糖尿病治疗的临床综合获益,探讨SZ-A用于MS治疗的发展潜力。 相似文献

Aims/Introduction: The glucose analogue, 1‐deoxynojirimycin (DNJ), found in mulberry (Morus alba) leaves, is a promising α‐glucosidase inhibitor. We evaluated the effect of the ingestion of mulberry leaf extract with enriched DNJ content on postprandial hyperglycemia in subjects with impaired glucose metabolism. Materials and Methods: In study 1, we carried out a randomized, double‐blind, crossover trial to assess the effects of single ingestion of mulberry leaf extract (3, 6 or 9 mg DNJ) or placebo on blood glucose and insulin concentrations during 2 h after a carbohydrate (200 g boiled white rice) challenge in 12 subjects with fasting plasma glucose (FPG) in the range of 100–140 mg/dL. Study 2 was a randomized, double‐blind, placebo‐controlled trial to assess the efficacy of 12‐week extract supplementation (6 mg DNJ, t.i.d.) for long‐term glycemic control in 76 subjects with FPG in the range of 110–140 mg/dL. Results: In study 1, ingestion of the mulberry leaf extract led to attenuated postchallenge acute glycemia in a dose‐dependent manner (P = 0.006, group × time interaction, two‐way anova ). In study 2, the serum 1,5‐anhydroglucitol concentration, a sensitive indicator of postprandial glycemic control, in the extract group increased and was higher than that in the placebo group over the 12‐week treatment period (P < 0.001, group × time interaction, two‐way anova ); no differences in FPG, glycated hemoglobin and glycated albumin concentrations were observed between the groups. Conclusions: Long‐term ingestion of mulberry leaf extract with enriched DNJ content could result in improved postprandial glycemic control in individuals with impaired glucose metabolism. These trials were registered with UMIN (no. UMIN000003154 and UMIN000003155). (J Diabetes Invest, doi: 10.1111/j.2040‐1124.2011.00101.x, 2011) 相似文献

BACKGROUND: Whether gastric acid secretion decreases with age is still controversial. With the discovery of Helicobacter pylori, the association of this bacterium with gastric acid secretion has also been discussed. The aim of this study was to investigate the relationship between gastric acid secretion, age and H. pylori infection. METHODS: The presence of H. pylori infection, the grade of fundic atrophic gastritis (FAG), and gastric acid secretion were investigated in 280 subjects without localized lesions in the upper gastrointestinal tract. Helicobacter pylori infection was confirmed by Giemsa and immunohistochemical staining, and FAG of biopsy specimens was graded on a scale of 0-4. RESULTS: Both basal and maximal acid output decreased with age in H. pylori-positive subjects, while they did not change with age in H. pylori-negative subjects. Gastric acid secretion decreased with the progression of FAG. An age-correlated decrease in gastric acid secretion in H. pylori-positive subjects depended on an increasing prevalence of FAG with age. CONCLUSIONS: In the population studied, advancing age had no influence on gastric acid secretion in H. pylori-negative subjects. Gastric acid secretion decreases with age in H. pylori-positive subjects because of the increasing prevalence of FAG with age. 相似文献

Treatment of type 2 diabetes (T2DM) is based on lifestyle changes and oral antidiabetic agents or insulin. The UKPDS study has confirmed metformin (Met) as the initial monotherapy. Accordingly, Met is widely regarded as the first drug of choice for most patients with T2DM. Safety and efficacy of sulphonylureas (SU) have been confirmed by several clinical trials. Recently, thiazolidinediones (TZD) have addressed some aspects of insulin-resistance that characterized several T2DM patients. However, SU and TZD are associated with various side effects that limit their use in many patients. New agents have been recently developed which potentiate the activity of the incretin (GLP1). GLP1, a gut hormone secreted in response to meal ingestion, is rapidly degraded by dipeptidylpeptidase-4 (DPP-4). GLP1 enhances insulin secretion and inhibits glucagon secretion in a glucose-dependent manner, delays gastric emptying and, in animal studies, preserves beta-cell mass by reducing apoptosis and stimulates of beta-cell proliferation. GLP1 levels are abnormally low in T2DM patients. Two classes of agents based on GLP1 have been launched: DPP-4 inhibitors and DPP-4 resistant GLP1 analogues. Randomized studies confirmed their efficacy to improve glycemic control in T2DM patients. Orally administered DPP-4 inhibitors reduce HbA1c by 0.5-1.1%, without hypoglycaemic events and no weight gain. The sub-cutaneous injected GLP1 analogues (exenatide and liraglutide) show larger reductions in HbA1c by 0.8-1.7% and weight loss but are associated with gastrointestinal side effects contributing to a significant treatment interruption. Several studies support the use of DPP-4 inhibitors in combination with Met as a promising second line treatment. 相似文献

Opium alkaloids have been used for centuries as potent antidiarrheals and analgesics, their constipating action in the latter instance taken as an unwanted effect. It was only during the last decade that the physiological role of opioid peptides present in both neurons and endocrine cells of the gastrointestinal (GI) tract has been defined. The recognition of distinct opioid receptor types which may be differentially involved in the control of motility, acid and electrolyte secretion in the GI tract presently focuses the attention of researchers in this field on the identification of receptor-type-selective opioid agonists in order to free these clinically extremely useful drugs from side effects. The present review provides a survey of mostly physiological data on the functional role of intestinal opioids. 相似文献

AimsThe aim of this study is to investigate the effects of a low-carbohydrate staple food (i.e., low-carbohydrate bread) on glucose and lipid metabolism and pancreatic and enteroendocrine hormone secretion in comparison with meals containing normal-carbohydrate bread, without consideration of the carbohydrate content of the side dishes.MethodsT2DM patients (n = 41) were provided meals containing low-carbohydrate bread (LB) together with side dishes or normal-carbohydrate bread (NB) together with side dishes every other day as a breakfast. Blood glucose levels were evaluated by using a continuous glucose monitoring system; blood samples were collected before and 1 and 2 h after the breakfast.ResultsPostprandial blood glucose levels, plasma insulin, plasma glucose-dependent insulinotropic polypeptide (GIP) and plasma triglyceride were significantly lower and plasma glucagon levels were significantly higher in LB compared with those in NB. Plasma glucagon-like peptide-1 (GLP-1) levels did not differ in the LB and NB groups.ConclusionsThese results indicate that changing only the carbohydrate content of the staple food has benefits on glucose and lipid metabolism in T2DM patients concomitant with the decrease of insulin and GIP secretion, which ameliorate body weight gain and insulin resistance. 相似文献

Postprandial gastrointestinal hormone secretion was not affected by the intravenous administration of naloxone. However, after the administration of morphine, multiple effects were observed. Postprandial pancreatic polypeptide, motilin, and enteroglucagon secretion were abolished and there was a reduction in the secretion of insulin, gastric inhibitory polypeptide, and neurotensin. There was prolonged secretion of gastrin. Levels of vasoactive intestinal polypeptide, somatostatin, and pancreatic glucagon were not affected. Many of these changes can be accounted for by the ability of morphine to delay gastric emptying. The prolonged secretion of gastrin could result from a combination of impaired gastric emptying and reduced postprandial gastric acid secretion. Inhibition of vagal acetylcholine release is the most likely explanation for the abolition of pancreatic polypeptide secretion. With the exception of the effects on motilin, pancreatic polypeptide, and enteroglucagon secretion this study provides no evidence that opiate substances directly affect the secretion of gastrointestinal hormones. 相似文献
