集中群组孕期保健模式的临床效果评价

目的探讨集中群组孕期保健模式的临床应用效果。方法选取2018年5-8月在兰州大学第一医院产科门诊就诊的孕28~34周的孕妇72例为研究对象,根据孕妇意愿分为干预组和对照组,每组各36例。对照组给予常规孕期保健模式干预,干预组给予集中群组孕期保健模式干预。分析干预前后孕妇分娩恐惧得分、助产士核心胜任力得分及妊娠结局等临床指标的差异。结果干预组孕妇分娩恐惧水平、剖宫产率明显下降,住院期间纯母乳喂养率明显提高,与对照组比较,差异均有统计学意义(均P<0. 05)。干预前后,助产士核心胜任力总均分显著提高,差异有统计学意义(P<0. 05)。结论集中群组孕期保健模式对保健者、孕妇及妊娠结局均具有积极促进作用,值得在临床推广与应用。     

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.

幼鼠内耳单个器官培养步骤及分类方法

内耳离体培养在研究内耳细胞功能、内耳组织发育再生、细胞损伤退化等方面具有重要价值。但由于内耳的组织结构微小复杂,其取材和培养具有较大难度,使该技术的普及和应用受到一定限制。本文在简要点评不同内耳离体培养方法优劣的基础上,结合本实验室多年来积累的实践经验,详细介绍了新生大鼠各个内耳终器取材及培养的具体步骤。从解剖迷路到分离终器,从凝胶制备到标本铺放,都有详细的操作指南,本文还针对各环节中的技术动作和关键事项进行了具体探讨并配以指导图例,希望这些内容能够弥补以往文献中抽象简略的条款式步骤所造成的实验困难,为开展内耳器官培养研究的初学者提供一定的帮助。
