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.

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...     

Glial regenerative response in the imaginal discs of Drosophila melanogaster

<正>Glial cells play a key role during nervous system development and actively participate in all the cellular processes involved in maintaining its structural robustness and functional plasticity.In response to neuronal damage,glial cells proliferate,migrate to the injured region and change their morphology,function,and behavior     

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.

慢性肾脏病非透析患者合并ACS80例血清肌钙蛋白相关因素的临床分析

目的:探讨影响慢性肾脏病非透析合并急性冠脉综合征(ACS)患者血清肌钙蛋白的相关因素研究。方法:回顾性分析2016年01月～2019年06月新疆自治区人民医院慢性肾脏病非透析合并ACS患者,收集患者的一般资料、实验室指标及肌钙蛋白T等,根据肌钙蛋白水平进行分组,采用多元逐步回归分析等方法进行相关性研究。结果:与对照组比较,观察组临床资料比较中TC、LDL、cTnT、CRP、Alb、iPTH及血磷有统计学意义;以cTnT为因变量,与对照组有差异的上述指标为自变量,采用多元逐步回归分析,结果显示:LDL(t=2. 306,P=0. 023)、CRP(t=2. 833,P=0. 011)及血磷(t=3. 0,P=0. 01)具有显著相关。采用ROC曲线分析发现观察组cTnT预测冠心病的AUC为0. 730,P值为0. 013,提示cTnT对于冠心病具有较好的预测作用。结论:CKD非透析合并ACS患者中血清肌钙蛋白与脂质代谢紊乱、炎症及钙磷代谢异常等因素有关,积极诊治可能改善患者的预后。
