子娴前期发作易感性的分子机制尚不明确。Erin Ciampa等人推测脑脊液(CSF)中不同蛋白的改变或许可影响中枢神经系统的病理生理变化,进而导致重度子娴前期的神经系统表现。

研究人员对13位子娴前期患者和14位正常对照的分娩前腰椎穿刺获得的CSF样本进行检测分析,基于核酸适配体的蛋白质组学在1310种蛋白中寻找表达变化的蛋白。

此外,研究人员利用独立信号通路分析强调显着发生改变的子娴前期特异性蛋白之间的相互关系。针对两种靶蛋白,研究人员通过ELISA验证出其CSF浓度差异。经SOMAscan发现了82种在子痫前期患者和健康对照的CSF中表达水平存在明显差异的蛋白(p<0.05)。差异性表达的蛋白围绕四个信号分子:TGF-β、VEGFA、血管紧张素原和IL-6。

通过ELISA证实子娴前期患者的TGF-β信号通路的激活素A(301.6±47.4 vs 151.6±20.5pg/ml;p=0.0074)和卵泡抑素相关基因(5129±347 vs 3016±188pg/mL;p<0.0001)表达上调。

总而言之,子娴前期患者的CSF中变化的蛋白主要汇集在对血管重构、炎症和神经发育、信号转导和电生理重要的信号通路上。

Hypertension:NfL(神经纤维丝轻链)可作为子娴前期诱导的神经损伤的血液标志物

现已证实子娴前期与之后的大脑结构和认知功能改变相关。Nf(神经纤维丝)是神经元的一种特殊的支架蛋白,其血清学定量检测可作为神经轴突损伤的生物标志物。Katrina Suzanne Evers等人在Basel大学医院进行了一前瞻性、纵向、单中心的研究,以确定有高子娴前期风险或子娴前期早期症状的单胎妊娠女性的血清Nf浓度。招募妊娠21周的孕妇,随访至分娩。197位孕妇有60位(30.5%)罹患子娴前期

Am J Obstet Gynecol:子娴前期患者的胎盘组织中MiR-30a-3p过表达,通过IGF-1影响绒毛膜细胞的侵袭和凋亡。

子痫前期(PE)影响了很多女性,仍是导致新生儿和产妇死亡的主要原因。很多研究人员认为胎盘miRNAs的异常表达与PE相关。目前,已在重度PE患者的胎盘中检测出34个PE相关的miRNAs,其中11个表达上调,23个表达下调。miR-30a-3p是PE患者中上调最显着的miRNAs中的一个。预测其靶点是胰岛素样生长因子(IGF-1),已有报道IGF-1在PE患者中表达下调。本研究致力于验证miR-3

Hypertension:高血压诊断标准降至130/80mmHg!

近期,美国心脏病学会/美国心脏协会临床实践指南专责小组修订了慢性高血压的诊断建议。新的分离系统包括确诊成人I期高血压:130-139/80-89mmHg。Alisse Hauspurg等人尝试对比子痫前期高危女性与I期高血压女性的预后,并且评估与血压正常的高风险的女性相比,I期高血压患者是否可受益于阿司匹林治疗。研究人员对高风险阿司匹林试验进行二次分析,包括子痫前期和糖尿病的女性。其中,827人(
