Here we present the case of a 64-year-old female with a duodenal carcinoid tumor treated by ligation-assisted endoscopic submucosal resection(ESMR-L) with circumferential mucosal incision(CMI). Band ligation was effective in resecting the duodenal carcinoid tumor after CMI,with an uneventful post-procedural course. Histopathological examination showed clear tumor margins at deeper tissue levels. Thus,in the present case,ESMR-L with CMI was useful for the treatment of duodenal carcinoid tumor.

BACKGROUND Gastric subepithelial tumors(SETs)may harbor potential *** it is well recognized that large SETs should be resected,the precise treatment strategy remains *** to surgical resection,endoscopic resection(ER)has many advantages;however,ER of SETs in the cardia is *** To evaluate the safety and efficacy of endoscopic full-thickness resection(EFTR)for the treatment of gastric cardia *** We retrospectively reviewed data from all patients with SETs originating from the muscularis propria layer in the gastric cardia that were treated by EFTR or submucosal tunneling ER(STER)at Zhongshan Hospital Fudan University between November 2014 and May *** characteristics and clinical outcomes,including procedure times and complications rates,were compared between groups of patients receiving EFTR and *** A total of 171 tumors were successfully removed[71(41.5%)tumors in the EFTR and 100(58.5%)tumors in the STER group].Gastrointestinal stromal tumors(GISTs)were the most common *** en bloc resection rate was 100%in the EFTR group vs 97.0%in STER group(P>0.05).Overall,the EFTR group had a higher complete resection rate than the STER group(98.6%vs 91.0%,P<0.05).The procedure time was also shorter in the EFTR group(44.63±28.66 min vs 53.36±27.34,P<0.05).The most common major complication in both groups was electrocoagulation *** was no significant difference in total complications between the two groups(21.1%vs 22.0%,P=0.89).CONCLUSION EFTR of gastric cardia SETs is a very promising method to facilitate complete resection with similar complications and reduced operative times compared to *** cases of suspected GISTs or an unclear diagnosis,EFTR should be recommended to ensure complete resection.

迄今,经历了30多年改革开放的中国社会,既进入改革的"深水区",也进入了现实"中国梦"的关键期。"中国梦"是一个复杂的系统工程,既需要顶层理论设计,也需要社会各领域的积极践行。"大政府·大社会"的发展模式是"中国梦"的顶层理论设计的核心。培育强大的社会力量是中国社会深层改革的一大目标,其基本途径即是在全力取缔不利于社会稳定与健康发展的社会组织的同时,鼓励、扶持有益于社会发展的社会组织。而社会组织爆发出巨大的社会能量,主要是在宪法与法律允许下,"去行政化"运作的结果。因此,如何处理"政府"与"社会组织"之间的关系,各级政府既不能将社会组织纳入行政体系之中,也不能听之任之、不加规范引导。本文以为,统战工作是联络、引导各种各样社会组织健康、有序发展的主要途径。因此,政府的统战部门应该积极调整工作思路,将社会组织纳入联络、引导的职能范围之中,条件成熟后,可成立社会组织联合会。

为探明叉角厉蝽Eocanthecona furcellata(Wolff)对草地贪夜蛾Spodoptera frugiperda(Smith)的控害潜能,本文研究了不同温度(17℃、22℃、27℃、32℃、37℃)条件下叉角厉蝽3~4龄若虫对草地贪夜蛾2~3龄幼虫的捕食作用,评估了其在不同温度下的生物防治效果。结果表明,在试验温度范围内叉角厉蝽3~4龄若虫对草地贪夜蛾2~3龄幼虫的捕食功能反应模型符合Holling Ⅱ型方程,捕食效能a/Th和日均捕食量均在32℃时最大。在同一温度下,叉角厉蝽3~4龄若虫的寻找效应与草地贪夜蛾幼虫密度呈负相关,但猎物密度相同时叉角厉蝽3~4龄若虫的寻找效应与温度呈正相关。在17℃~37℃范围内,Hassell-Varley干扰反应模型能较好地反映出不同叉角厉蝽密度条件下对草地贪夜蛾的捕食情况;在相同的猎物密度条件下叉角厉蝽3~4龄若虫个体间存在种内竞争和自我干扰作用,随着自身密度增大,相互干扰作用增强,搜寻系数Q和相互干扰系数m随着温度升高而增大,在37℃时最大,分别为0.4719和0.788。本试验证实了叉角厉蝽若虫在温度为32℃、猎物密度为60(头/皿)条件下对草地贪夜蛾的日捕食量最大,但随着温度升高,若虫的捕食量趋于饱和或出现下降趋势,在37℃温度条件下种内竞争和自我干扰作用最强。
