摘要： 针对我们进行的教育信息化和高职人体解剖学教学融合的初步探索,我们进行了问卷调查,并观察记录了学生课堂表现以、课堂秩序情况,分析了学生的随堂测试情况。总的来说,我们进行的教育信息化与我们的教学融合的探索提升了学生的教学参与度,并对学生良好学习习惯培养以及自学能力提升都起了明显的促进作用,但是,探索的过程是长期的,后面仍需要继续优化教育信息化与教学融合对教学模式方面的革新,促使教学手段多样化,教学效果最优化。

关键词： autism   cognitive inflexibility   grey matter volume   perceptual symptom  

摘要： Overly stable visual perception seen in individuals with autism spectrum disorder (ASD) is related to higher-order core symptoms of the condition. However, the neural basis by which these seemingly different symptoms are simultaneously observed in individuals with ASD remains unclear. Here, we aimed to identify such a neuroanatomical substrate linking perceptual stability to autistic cognitive rigidity, a part of core restricted, repetitive behaviors (RRBs). First, using a bistable visual perception test, we measured the perceptual stability of 22 high-functioning adults with ASD and 22 age-, IQ-, and sex-matched typically developing human individuals and confirmed overstable visual perception in autism. Next, using a spontaneous task-switching (TS) test, we showed that the individuals with ASD were more likely to repeat the same task voluntarily and spontaneously, and such rigid TS behavior was associated with the severity of their RRB symptoms. We then compared these perceptual and cognitive behaviors and found a significant correlation between them for individuals with ASD. Finally, we found that this behavioral link was supported by a smaller gray matter volume (GMV) of the posterior superior parietal lobule (pSPL) in individuals with ASD. Moreover, this smaller GMV in the pSPL was also associated with the RRB symptoms and replicated in two independent datasets. Our findings suggest that the pSPL could be one of the neuroanatomical mediators of cognitive and perceptual inflexibility in autism, which could help a unified biological understanding of the mechanisms underpinning diverse symptoms of this developmental disorder.

摘要： 分析胸锁关节解剖学及生物力学特征,以为临床治疗胸锁关节脱位及周围骨折提供数据参考。方法:选取10具(20侧)胸锁关节标本予以胸锁韧带解剖学测量、胸锁关节生物力学实验及锁骨内侧端及胸骨柄关节面积测量。结果:胸锁前后韧带解剖参数相较无统计学差异(P>0.05);负载2、4N时胸锁关节负载前后成角无差异(P>0.05),在负载6、8、10N时差异呈显著性(P<0.05);左、右侧测量数据相较P>0.05;但胸骨柄关节面积明显小于锁骨内侧端关节面积(P<0.05)。结论:胸锁关节的稳定性主要取决于周围韧带、关节盘等,其中胸锁前后韧带主要为限制关节向前、向后成角,关节盘可增加关节适应性,在行手术复位与内固定时应重视对韧带及关节盘的修复与重建。
