注意缺陷多动障碍(ADHD)是一种以注意力不集中、多动冲动和工作记忆缺陷为特征的慢性神经发育障碍。社交障碍是ADHD患儿面临的主要挑战之一。研究发现ADHD患儿在面部表情识别(FER)任务中的表现通常不如正常发育的儿童。虽然部分研究表明在特定表情识别的准确性上,ADHD患儿与正常发育儿童相比未见明显差异,但总体来看,他们在FER中显示出一定的困难。这些困难的神经心理机制如下:①神经解剖学方面:ADHD患儿的杏仁核和内侧额叶区域显示出较小的灰质体积和表面积,以及部分额叶白质纤维束的轴突/细胞的密度和体积减小;②神经生理学方面:ADHD患儿的脑电图表现出慢波活动增加,在面对面部刺激时情绪调节和对愤怒面孔的反应上有异常;③心理学方面:心理社会压力可能会影响ADHD患儿的FER能力,且ADHD患儿睡眠剥夺可能导致其对悲伤和愤怒等负面表情的识别阈值显著提高。本文对近三年来有关ADHD患儿FER能力的研究进行检索和整理,从神经解剖学、神经生理学以及心理学机制三个维度分析ADHD患儿的FER缺陷,以期为ADHD的深入研究和临床治疗提供新的视角。

针对ZSM-5分子筛微孔扩散限制和催化活性位单一的问题,使用有序大孔-介孔碳模板为硬模板并结合原位引入金属策略,一步晶化合成了具有高结晶度、高比表面积的有序贯通大孔-介孔-微孔等级结构的Fe/ZSM-5分子筛单晶.通过X射线衍射(XRD)、紫外-可见光谱(UV-Vis)、H_(2)程序升温还原实验(H2-TPR)和X射线光电子能谱(XPS)等手段对催化剂中活性Fe的存在形式进行了表征.结果表明,该材料中位于离子交换位及铁氧八面体(六配位)的孤立Fe(III)是主要的氧化还原活性中心,当Fe负载量(质量分数)为1%时,苯甲醇转化率最高为59.3%,产物选择性为83.2%,最终收率达到49.3%,在循环使用5次后仍保持高催化活性.

目的对比分析宫颈环扎术和药物治疗对宫颈机能不全(CI)患者分娩方式及妊娠结局的影响。方法回顾性分析2020年7月至2022年7月期间桐乡市妇幼保健院和嘉兴市妇幼保健院收治的55例CI患者的临床资料,并按治疗方式的不同分成药物组(n=25)和环扎组(n=30)。药物组给予药物保守治疗,环扎组给予宫颈环扎术治疗。比较两组分娩方式、妊娠结局和并发症发生情况。结果环扎组阴道分娩率为16.67%,低于药物组的45.83%;剖宫产率为83.33%,高于药物组的54.17%(P0.05);环扎组早产率低于药物组,足月产率高于药物组(P0.05),且环扎组患者胎膜早破发生率低于药物组(P<0.05)。结论宫颈环扎术相比于药物保守治疗对CI患者的临床效果更加显著,能改变分娩方式和妊娠结局,且安全性较高。
