Plasma levels of acylated ghrelin in patients with functional dyspepsia

AIM:To investigate the relationship between plasma acylated ghrelin levels and the pathophysiology of functional dyspepsia.METHODS:Twenty-two female patients with functional dyspepsia and twelve healthy volunteers were recruited for the study.The functional dyspepsia patients were each diagnosed based on the Rome Ⅲ criteria.Eligible patients completed a questionnaire concerning the severity of 10 symptoms.Plasma acylated ghrelin levels before and after a meal were determined in the study participants using a commercial human acylated enzyme immunoassay kit;electrogastrograms were performed for 50 min before and after a standardized 10-min meal containing 265 kcal.RESULTS:There were no significant differences in plasma acylated ghrelin levels between healthy volunteers and patients with functional dyspepsia.However,in patients with functional dyspepsia,there was a negative correlation between fasting plasma acylated ghrelin levels and the sum score of epigastric pain(r =-0.427,P = 0.047) and a positive correlation between the postprandial/fasting plasma acylated ghrelin ratio and the sum score of early satiety(r = 0.428,P =0.047).Additionally,there was a negative correlation between fasting acylated ghrelin plasma levels and fasting normogastria(%)(r =-0.522,P = 0.013).Interestingly,two functional dyspepsia patients showed paradoxically elevated plasma acylated ghrelin levels after the meal.CONCLUSION:Abnormal plasma acylated ghrelin levels before or after a meal may be related to several of the dyspeptic symptoms seen in patients with functional dyspepsia.

A novel device for endoscopic submucosal dissection,the Fork knife

瞄准：用一台新奇设备介绍并且评估功效和内视镜的粘膜下层解剖(ESD ) 的技术方面，叉刀。方法：从 2004 年 3 月到 2008 年 4 月， ESD 在一个单个第三级的工作分派中心用 Flexknife (组 B ) 在使用一把叉刀(Endo FSregister )( 组 A ) 的 265 胃的损害上并且在 72 胃的损害上被执行。我们回顾地比较了 resected 标本的肿瘤，病理检查所见，和尺寸的内视镜的特征。我们也比较了在二个组之间的整块切除术率，完全的切除术率，复杂并发症，和过程时间。结果：resected 标本的吝啬的尺寸是 4.27 +/- 在组 A 和 4.29 +/- 的 1.26 厘米在组 B 的 1.48 厘米。整块切除术率是 95.8%(254/265 损害) 在组 A 并且 93.1%(67/72 ) 在组 B。没有 resected 边缘的肿瘤房间侵略的完全的 ESD 在 81.1% 被获得(215/265 ) 组 A 并且在 73.6%(53/72 ) 组 B。穿孔率是 0.8%(2/265 ) 在组 A 并且 1.4%(1/72 ) 在组 B。吝啬的过程时间是 59.63 +/- 在组 A 和 76.65 +/- 的 56.12 min 在组 B 的 70.75 min (P 【 0.05 ) 。结论：叉刀(Endo FSregister ) 为临床的实践是有用的并且有的优点减少过程时间。
