Sex-biased autophagy as a potential mechanism mediating sex differences in ischemic stroke outcome

Stroke is the second leading cause of death and a major cause of disability worldwide, and biological sex is an important determining factor in stroke incidence and pathology. From childhood through adulthood, men have a higher incidence of stroke compared with women. Abundant research has confirmed the beneficial effects of estrogen in experimental ischemic stroke but genetic factors such as the X-chromosome complement can also play an important role in determining sex differences in stroke.

颅前窝底及鞍区肿瘤手术入路的研究进展

颅前窝底及鞍区因涉及的解剖区域结构复杂,手术技术难度大、风险高,一直是神经外科医生所面临的难题。近年来,随着微侵袭观念的不断传播,显微器械和内镜器械的发展以及神经外科技术的日臻成熟,颅前窝底及鞍区肿瘤的治疗也得到飞速发展,相关技术日臻成熟。本文就颅前窝底肿瘤手术入路的进展作一综述。     

新冠肺炎疫情背景下心理援助团体督导中的议题与焦点

目的:探究新冠肺炎疫情心理援助热线平台所开展的团体督导中的重要议题和督导焦点。方法:对教育部华中师范大学心理援助热线平台的21名咨询师进行访谈，询问督导中发生的令人深受启发的重要督导片段，之后基于督导区辨模型分析重要督导片段的议题和焦点。结果:在新冠肺炎疫情心理援助热线咨询师所参与的团体督导中，议题主要分为应对疑难个案、处理咨询师个人议题和讨论心理援助基本设置3类；督导中最关注的督导焦点是历程化技能；不同议题下督导焦点不同，应对疑难个案的督导更关注历程化技能和概念化技能，处理咨询师个人议题的督导更关注个人化技能，而讨论心理援助设置的督导对3个督导焦点的关注较平均。结论:新冠肺炎疫情背景下心理援助热线团体督导的议题主要分为3类，不同议题的督导焦点存在不同。     

Establishment of an optimized CTC detection model consisting of EpCAM,MUC1 and WT1 in epithelial ovarian cancer and its correlation with clinical characteristics

Objective: Emerging studies have demonstrated the promising clinical value of circulating tumor cells(CTCs)for diagnosis, disease assessment, treatment monitoring and prognosis in epithelial ovarian cancer. However, the clinical application of CTC remains restricted due to diverse detection techniques with variable sensitivity and specificity and a lack of common standards.Methods: We enrolled 160 patients with epithelial ovarian cancer as the experimental group, and 90 patients including 50 pat...

Tandem pore TWIK-related potassium channels and neuroprotection

TWIK-related potassium channels(TREK) belong to a subfamily of the two-pore domain potassium channels family with three members, TREK1, TREK2 and TWIK-related arachidonic acid-activated potassium channels. The two-pore domain potassium channels is the last big family of channels being discovered, therefore it is not surprising that most of the information we know about TREK channels predominantly comes from the study of heterologously expressed channels. Notwithstanding, in this review we pay special attention to the limited amount of information available on native TREK-like channels and real neurons in relation to neuroprotection. Mainly we focus on the role of free fatty acids, lysophospholipids and other neuroprotective agents like riluzole in the modulation of TREK channels, emphasizing on how important this modulation may be for the development of new therapies against neuropathic pain, depression, schizophrenia, epilepsy, ischemia and cardiac complications.

老年非瓣膜性心房颤动住院患者缺血性脑卒中的预测因素

目的探讨老年非瓣膜性心房颤动(non-valvular atrial fibrillation,NVAF)住院患者缺血性脑卒中(ischemic stroke,IS)的预测因素。方法选择2013年1月～2017年6月福建医科大学附属协和医院住院的老年NVAF患者314例,根据是否合并IS分为NVAF组239例,NVAF+IS组75例。多因素logistic回归分析老年NVAF住院患者发生IS的影响因素,ROC曲线下面积(AUC)探讨各影响因素的预测价值。结果 NVAF+IS组年龄、收缩压、高血压、外周血管疾病、CHADS_2、CHA_2DS_2-VASc、左心房内径、左心房内径指数、左心室质量和左心室质量指数明显高于NVAF组,估算的肾小球滤过率(estimated glomerular filtration rate,eGFR)明显低于NVAF组,差异有统计学意义(P0.05,P0.01)。多因素logistic回归分析显示,eGFR、左心房内径、左心房内径指数、左心室质量、左心室质量指数是老年NVAF住院患者发生IS的独立危险因素(P 0.05,P 0.01)。CHADS_2、CHA_2DS_2-VASc、左心房内径指数及eGFR预测老年NVAF住院患者发生IS的AUC分别为0.541、0.525、0.577、0.577,CHADS_2+左心房内径指数+eGFR的AUC分别高于CHADS_2、CHADS_2+左心房内径指数、CHADS_2+eGFR的AUC(0.621 vs 0.541、0.585、0.588,P0.05);CHA_2DS_2-VASc+左心房内径指数+eGFR的AUC分别高于CHA_2DS_2-VASc、CHA_2DS_2-VASc+左心房内径指数、CHA_2DS_2-VASc+eGFR的AUC(0.626 vs0.525、0.586、0.591,P0.05)。结论 CHADS_2、CHA_2DS_2-VASc分别联合eGFR和左心房内径指数对老年NVAF住院患者发生IS的预测能力分别高于CHADS_2、CHA_2DS_2-VASc。
