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.

基于苗药五藤膏外敷对CIA大鼠炎性骨破坏的影响探讨苗医外治就近驱邪的作用＊

目的 通过研究明确苗药五藤膏外敷缓解胶原诱导性关节炎（CIA）大鼠关节局部炎症和骨破坏的机制，证实苗医外治就近驱邪的作用。方法 将70只Wistar大鼠随机分为空白组、模型组、苗药五藤膏高、中、低剂量组、扶他林组及IL-17阻断组，每组10只。除空白组外，其余6组均构建CIA模型，并给予相应的外敷治疗。观察大鼠一般情况，HE染色进行病理学分析，TRAP染色检测OC生成，ELISA检测各炎症因子的含量，RT-PCR和WB分别检测RANKL的基因及蛋白表达。结果 苗药五藤膏能改善CIA大鼠破骨细胞浸润及关节病理性结构，并降低RANKL蛋白、基因表达以及TNF-α、IL-1、IL-6、IL-17含量。结论 苗药五藤膏外敷剂对CIA大鼠的治疗机制可能与降低致炎因子的分泌，抑制RANKL及OC的表达相关。     

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...

基于数据挖掘分析 ULBP2在结直肠癌中的表达及预后意义

摘要:目的 利用 Oncomine、TCGA(TheCancerGenomeAtlas)等公共数据库,分析 UL16结合蛋白2(ULBP2)基 因在结直肠癌中的表达及临床意义。方法 通过 Oncomine数据库检索关于 ULBP2基因转录组 mRNA 信息,分析 ULBP2在不同类型肿瘤中的表达情况;TCGA 数据库分析 ULBP2基因与结直肠癌的预后关系;利用String数据库分析 ULBP2与上下游蛋白的相互作用及功能富集分析。结果 Oncomine数据库中共有352项关于 ULBP2基因的研究结 果,其中有统计学差异的结果有23项,涉及到结直肠癌和结直肠正常组织的研究数据集共有10项,其中结直肠癌组织 中 ULBP2基因的表达显著高于结直肠正常组织(P<0.05);对 TCGA 数据库结直肠癌数据进行生存分析,结果表明在 结直肠癌患者中 ULBP2基因高表达组的生存率明显低于低表达组(P<0.05)。结论 大数据分析结果表明,ULBP2基 因在结直肠癌组织中呈现高表达,并与患者的预后相关,可能作为其潜在的治疗靶点。     

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.
