Sexual Behavioral Disinhibition Associated with Nucleus Lentiformis Lesion: A Forensic Neuroscience Perspective Through a Case

Organic brain disturbances particularly related to frontal cortex structures and subcortical areas including the basal ganglia may play a role in behavioral disinhibition disorders. Kluver–Bucy syndrome (KBS), which is one of the better knowns of these syndromes, includes hyperorality, visual agnosia, and hypersexuality, has been reported to occur after temporal lobe and amygdala lesions; however, several patients who had focal lesions in areas other than the temporal cortex and amygdala have been reported to present partial KBS symptoms. Nucleus lentiformis refers to a large portion of the basal ganglia including the putamen and globus pallidus, and specific structures within this broad area are known to be important for reward and value-based decision making. To date, KBS symptoms including hypersexual behavior associated with nucleus lentiformis lesions have never been reported. Here, we present a 38-year-old male patient who developed increased sexual interest and hyperorality after infarctions in the right lenticular nucleus and right occipitotemporal region and committed a first-degree sexual assault. He was sent to our institution for the assessment of criminal responsibility to the index sexual crime. According to a comprehensive and thorough forensic psychiatric evaluation, he was diagnosed as having an organic personality disorder with partial KBS symptoms. To the best of our knowledge, this is the first reported case of deviant sexual behavior and hyperorality developing after nucleus lentiformis infarction. We aimed to discuss possible neurobiologic explanations of late-onset deviant sexual behavior, which resulted in sexual criminal behavior following a cerebrovascular infarction.

Two consecutive fatal cases of acute myocardial infarction caused by free floating thrombus in the ascending aorta and review of literature

Free floating thrombus in the ascending aorta is an uncommon source of acute myocardial infarction. We report on two cases of young women who died of acute myocardial infarction caused by a free floating thrombus in the sinus of Valsalva obstructing the coronary arteries' ostia. The first case reports on a 30-year-old pregnant woman who anamnestically had episodes with short loss of consciousness and weakness. The second case presents a 37-year-old woman suffering from multiple sclerosis with no previous history of thrombotic events. The review of literature revealed a predominance of women (eight females and three males). Interestingly, the coronary arteries bear no preference concerning the right (RCA) or left coronary artery (LCA) being more often occluded by a free floating thrombus. Especially, younger women (mean age 45.5 years, range 30-59 years) with no history of cardiac symptoms and without atherosclerotic changes seem to be predispositioned. The hypothesis that thrombus formation in cases without plaque disruption may depend on an endothelial erosion which seems to be more common in younger women and promoted by a hyperthrombogenic state is supported by our two cases. A comprehensive literature search revealed, that these are the first two reports on a free floating thrombus being the cause of fatal acute myocardial infarction in a pregnant woman, respectively, a woman suffering from multiple sclerosis.     

浅析“扶老困局”的消解路径

＂乐于助人＂、＂尊老爱幼＂是中华民族的传统美德,然而＂老人摔倒无人敢扶＂已经成为日常生活中的一个景象,这虽然是社会转型时期的社会失范导致的短暂社会现象,但也应该引起我们对社会公德和法律冲突的思考,积极探索＂扶老困局＂的消解路理十分必要。     

Sudden Collapse due to Medullary and Cervical Cord Infarction—An Unusual Presentation of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is a common cancer worldwide with a great potential for metastatic spread. Hepatocellular carcinoma often arises in people with underlying viral hepatitides or liver cirrhosis and may present in various ways including abdominal pain, liver mass, and signs of hepatocellular decompensation. Many tumors may have metastasized to other organs such as the lungs, lymph nodes, bone, and adrenal glands at the time of diagnosis. However, it is uncommon for HCC to present purely due to its metastasis, such as spinal cord compression from vertebral metastasis. Here, an unusual presentation of a sudden cardiovascular collapse due to medullary and cervical cord infarction from compression of the cervical cord is presented. The importance of clinical investigations, the usefulness of postmortem computed tomography scans, and the examination of the cervical spine and cervical cord in people with no obvious cause of death after standard autopsy procedures are emphasized.     

元丽民俗文化研究——以《老乞大》为例

《老乞大》作为语言学研究的珍贵资料，一直受到学者的关注，成果也很丰富。但《老乞大》还记录了当时社会的饮食习惯、衣着服饰、传统习俗等方面的情况，对研究元丽的民俗文化具有重要作用。文章从民俗文化的角度，来探讨一下《老乞大》中所反映的当时中韩两国之间的民俗事象及其差异所在。     

电针心经穴位对急性心肌缺血模型大鼠内侧隔核白细胞介素-2、JunB蛋白及c-fos表达水平的影响

目的 观察电针心经对急性心肌缺血（acute myocardial ischemia,AMI）大鼠内侧隔核白细胞介素（interleukin,IL）-2水平、JunB蛋白及c-fos表达水平的影响,探究内侧隔核在针刺抗AMI中的作用及机制。方法 将大鼠分为伪手术组、模型组和电针组,每组6只;结扎冠状动脉左前降支复制AMI大鼠模型;电针组大鼠选取手少阴心经“神门—通里”段进行干预,每次30 min,每日1次,连续电针3 d,刺激电流为1 mA,频率为2 Hz;伪手术组、模型组大鼠不进行电针干预。采用ELISA法检测大鼠大脑内侧隔核IL-2水平,Western blot法检测大鼠大脑内侧隔核区JunB蛋白表达水平,免疫荧光法检测大鼠大脑内侧隔核区c-fos免疫反应阳性神经元表达水平。结果 与伪手术组比较,模型组大鼠大脑内侧隔核区IL-2、JunB蛋白水平显著升高（P＜0.05）,c-fos免疫反应阳性神经元数和平均吸光度（optical density,OD）值显著增加（P＜0.05）;与模型组比较,电针组大鼠大脑内侧隔核区IL-2、JunB蛋白水平显著降低（P＜0.05）,c-fos免疫反应阳性神经元数和平均OD值显著减少（P＜0.05）。结论 内侧隔核参与电针心经抗AMI的作用,其机制可能与电针降低大脑内侧隔核区IL-2、JunB蛋白及c-fos表达水平有关。     

马克思的革命旨趣与历史唯物主义

历史唯物主义作为蕴含着马克思毕生革命旨趣的新唯物主义,是马克思改变世界的思想基石。马克思认为,黑格尔的唯心主义只是观念地呈现了历史的发展过程。为了回到现实的历史,马克思以历史唯物主义来克服唯心主义的抽象性,以揭露社会生活中复杂的现实矛盾。从思想史背景上讲,马克思的新唯物主义既受到了费尔巴哈和18世纪法国唯物主义思想的影响,但又提升并超越了旧唯物主义的局限性,赋予唯物主义一种全新的时代内涵和理论效用,从而为现实的人的自由与解放提供了历史路标。     

LSAB法检测肌动蛋白肌红蛋白纤维联接蛋白在心肌梗死中的应用

利用LSAB法，比较抗肌动蛋白单克隆抗体（HHF35）、抗肌红蛋白（Mb）和抗纤维联接蛋白（Fn）多克隆抗体在22例实际案例人心肌梗死检材中的应用效果。发现：在22例人心肌切片中，HE均能显示明显心肌梗死区，三种抗体的免疫组化都能在同区内显示心肌梗死，对于梗死心肌细胞的反应，表现为HHF35、Mb出现心肌细胞的缺染或弱染，Fn在梗死心肌细胞呈阳性特异性染色。图像分析表明：在相同视野内梗死面积所占比率为HHF35＞Fn＞Mb＞HE；在染色效果上，HHF35明显最佳。
