国际护胃日”又称“国际养胃日”,2006年的4月9日被国际自然医学和养生工程研究会、世界健康管理联盟定为第一个“国际养胃日”,今年4月9日是第15个“国际护胃日”。 脾胃乃后天之本。中国是“胃病大国”,十人九胃,我国胃癌的发病率目前在所有恶性肿瘤中占第二位,死亡率高居第三位。更为严峻的是,目前我国每年胃癌新发病例超过42万例,占到全球新发病例总数的42%,居全球首位。大量研究发现,胃病高发的 罪魁祸首,便是 幽门螺旋杆菌(下称:HP)感染 。 解决胃病,不能忽视幽门螺杆菌 大多数胃病都是由于幽门螺杆菌感染。如果已经有幽门螺杆菌感染的迹象:消化不良、饭后打嗝、反酸、胃痛、口臭,那么就要尽快清除干净,不仅是因为不清除,胃病就无法好,还因为它能将人类患上胃癌的几率提高4-6倍。幽门螺杆菌会通过 口口传播(唾液)、粪口传播 ,在人群中的感染率很高,中国人的幽门螺杆菌感染率保守估计在60%。 解决幽门螺杆菌,食疗很重要 胃病三分治七分养,所以如果出现幽门螺杆菌超标、胃部不适的话,在日常生活中一定要重视胃部的养护。不管是早饭、午饭,还是晚饭,都要做到只吃七八分饱。糯米类的食物比如粽子、青团、糯米饭等黏糊糊的食物尽量少吃,酒精、辛辣刺激食物要尽量避免。作息方面,一定要减少或 避免熬夜 ,因为熬夜会干扰胃黏膜的修复。此外,可适当多食用猴菇、秋葵、山药等 黏滑食物 ,建议 每日补充岩藻多糖 (海带表面黏液)。 岩藻多糖:靶向 吸附 清除HP、修护胃黏膜 岩藻多糖又名褐藻糖胶、褐藻多糖硫酸酯,提取自 葛洪《肘后备急方》 收录的昆布等褐藻表面黏液,富含L-岩藻糖和有机硫酸根,是海洋中独有的天然功能型多糖(可分为食品级、药用级)。以昆布、裙带菜等褐藻为食物的海参、鲍鱼,通过食物链其体内会富集少量的岩藻多糖,这些岩藻多糖及其衍生物成为 海参、鲍鱼 等养生保健价值的重要组成部分( 杨玉红. 海参岩藻聚糖硫酸酯抗肿瘤活性及作用机制的研究 . 中国海洋大学, 2012 )。大量研究发现,岩藻多糖对清除幽门螺杆菌效果独特,且能修护胃黏膜,是 安全清幽的新选择 (目前,针对幽门螺杆菌的四联方等抗生素疗法耐药性越发严重、副作用大)。 2011年 ,《International Immunopharmacology》报道岩藻多糖可以保护阿司匹林引发的胃黏膜损伤。 2012年 ,《Food Chemistry》报道岩藻多糖可以保护酒精性胃损伤 2014年 , 2014年,韩国Chungbuk National University大学Yun-Bae Kim研究团队在《Lab Anim Res》发表研究显示,岩藻多糖浓度为100μg/mL时能够完全抑制幽门螺旋杆菌的增殖。 2015年 ,发表在《癌症治疗》(Journal of Cancer Therapy)期刊上的一项日本临床研究强调了岩藻多糖应该被作为胃癌患者的膳食补充剂,以减少患者化疗副作用,延长生命期。 2019年 ,海藻活性物质国家重点实验室与青岛大学附属医院合作进行的临床研究表明,岩藻多糖配合四联疗法能够增强临床幽门螺杆菌根除率。 (1)Shibata H , KimuraTakagi I , Nagaoka M , Hashimoto S , et al.

Protective effect of sea cucumber (Acaudina molpadioides) fucoidan against ethanol-induced gastric damage Abstract: Sea cucumber is a nutritional aquatic food that is widely consumed in East Asian countries. Employing a rat model of ethanol-induced gastric ulcer, we examined the protective effect of sea cucumber fucoidan (SC-FUC) extracted from Acaudina molpadioides and explored the related mechanisms. Oral administration with 100 mg/kg body weight SC-FUC for 5 days can significantly prevent the formation of gastric ulcer. Moreover, SC-FUC pretreatment could alleviate ethanol-induced histological damage, reverse changes in tissue oxidation and antioxidase activities, and regulate the signalling pathways of mitogen-activated protein kinases and matrix metalloproteinases. This study investigated the ethanolinduced gastric ulcer protective effect of SC-FUC for the first time, and elucidated that the protective mechanisms included anti-oxidation, gastric matrix hydrolysis suppression, and anti-inflammation.

明月新品: 岩藻多糖 功能特性 岩藻多糖,也称褐藻多糖硫酸酯或褐藻糖胶(fucoidan),是由含硫酸基的岩藻糖(fucose)所构成海洋复合多糖物质。 岩藻多糖主要存在于褐藻表面的黏液中,如海带、海蕴及裙带菜孢子叶等。 李时珍《本草纲目》中记载,褐藻能“治水病,瘿瘤,功同海藻”,另外,《医林篡要》提高褐藻能够“补心行水,消痰,软坚,消瘿结核,攻寒热瘕疝,治脚气水肿,通噎膈”。 岩藻多糖是1913年由瑞典乌普萨拉大学Kylin H.Z.教授从海带黏滑液中发现的。 Kylin, H.Z. Biochemistry of sea algae. HZ Physiol. Chem. 1913, 83, 171–197. 化学结构 1931年,Bird和Haas教授用乙醇沉淀的方法从掌状海带中提取出岩藻多糖,从中得到了30.3%的硫酸盐,首次将岩藻多糖定义为含有硫酸基的多糖化合物。(Biochem. J., 1931, 25, 403) 1937年,Gulbrand Lande教授采用乙醇沉淀法从掌状海带中提取出岩藻多糖,通过盐酸蒸馏的方法推测出其中含有岩藻糖。( Biological Chemistry, 1937, 247:189-196 ) 1999年,Daniel与Chevolot教授先后发现了岩藻多糖的结构中糖苷键类型为α-1,3及α-1,4连接。(Carbohyd. Res., 1999, 319, 154–165; Carbohyd. Res., 1999, 322, 291–297.) 产品功效 目前,医学界正在对岩藻多糖进行各种健康功效的研究,已经于国际医学期刊发表上千篇论文研究,证实具有多种生物功能,如 抗幽门螺旋杆菌:Besednova N N, Zaporozhets T S, Somova L M, et al.

Abstract The present study investigated the preventive effects of etodolac, a selective cyclo-oxygenase (COX)-2 inhibitor, on metachronous cancer development after endoscopic resection of early gastric cancer. Among 267 early gastric cancer patients who underwent endoscopic resection, 47 patients with extensive metaplastic gastritis were selected based on endoscopic findings and our previously described criteria of serum pepsinogen (PG) test-positive and Helicobacter pylori antibody-negative conditions. Nonrandomized etodolac treatment (300 mg/day) was administered to 26 patients (Group A), while the remaining 21 patients were untreated (Group B). No significant differences in age, sex distribution, lifestyle factors or extent of metaplastic gastritis at baseline were identified between groups. Patients were followed for metachronous cancer development with endoscopy every 6-12 months for up to 5 years. Mean (standard deviation) follow-up period was 4.2 (0.9) years. In Group B, 5 cancers developed (incidence rate = 6,266/100,000 person-years), significantly more than the 1 cancer in Group A (incidence rate = 898/100,000 person-years; p 0.05). Long-term etodolac treatment did not influence the extent of metaplastic gastritis as revealed by endoscopic findings or by serum PG levels, but effectively reduced metachronous cancer development in patients with extensive metaplastic gastritis. These results strongly suggest that chemoprevention of cancer in the metaplastic stomach is possible by controlling COX-2 expression.
