硝酸甘油联合甲基多巴治疗重度子痫前期的效果研究

目的:探讨硝酸甘油联合甲基多巴治疗重度子痫前期的临床效果及对围产结局的影响。方法:选取2015年5月～2018年6月我院收治的重度子痫前期患者81例作为研究对象,根据患者入院先后顺序分为对照组(40例)和观察组(41例),对照组给予常规治疗,观察组在对照组的基础上给予硝酸甘油联合甲基多巴治疗。比较两组患者的临床治疗效果、治疗前后平均动脉压(MAP)、24h尿蛋白(24 pro)和心率(HR)水平的变化及围产结局。结果:治疗后,观察组患者的总有效率显著高于对照组(95.12%vs. 80%,P0.05),两组MAP、24 pro和HR水平均较治疗前显著下降,且观察组的MAP和24 pro水平显著低于对照组(P0.05);观察组患者的产后出血、胎盘早剥、胎儿窘迫和新生儿窒息的发生率显著低于对照组,自然分娩率显著高于对照组(P0.05),两组的低体重儿的发生率相比无统计学差异(P0.05)。结论:硝酸甘油联合甲基多巴可有效降低重度子痫前期患者的血压和24 pro水平,提高自然分娩率,改善围产结局,显著提高临床效果。     

36例子痫的抢救及护理

子痫是妊娠高血压综合征最严重的阶段,常发生于妊娠晚期、产前及产后.一旦发生,往往危及母婴安危.医护人员要密切配合,在积极组织抢救治疗的同时给予正确护理,预后良好.我院近几年收治36例,现将护理体会总结如下.     

sHLA-G在子痫前期患者的表达及意义

目的：检测子痫前期患者sHLA—G水平,探讨母血sHLA—G的水平和妊娠高血压疾病的关系。方法：采用酶联免疫吸附法检测20例正常孕妇晚期和20例子痫前期患者血清sHLA—G水平。结果：在正常妊娠组sHLA—G血清中的水平为10．72±3.40ng／mL;子痫前期组为9.46±1.5．10ng／mL。子痫前期组sHLA—G水平明显低于正常妊娠晚期组,差异有显著性意义（P〈0．05）。结论：sHLA-G可能与子痫前期患者的发病有关系。     

miR-15b在内皮细胞的功能及其与血管相关性疾病的关系

微小RNA(MicroRNA, miRNA)是长度为22个核苷酸的小片段非编码RNA,作为RNA干扰的参与者之一,其通过在转录后水平调节各种基因的表达,进而对细胞的生命活动产生广泛影响。miR-15b是miR-15/16家族一员,是一类在机体各系统、特别是血管内皮系统广泛表达的微小RNA,主要影响细胞的增殖、凋亡、侵袭、成管等行为。文章主要对miR-15b及相关家族成员在各类细胞、特别是血管内皮细胞的生物学行为、作用机制及miR-15b在心血管相关疾病的发生、发展及预后等过程中的作用进行了详细阐述。同时,文章对miR-15b相关家族成员在以胎盘内皮发育异常为病理基础的妊娠期高血压疾病如子痫前期的发病机制中的作用进行了探讨。     

Screening Preeclamptic Cord Plasma for Proteins Associated with Decreased Breast Cancer Susceptibility

Preeclampsia, a complication of pregnancy characterized by hypertension and proteinuria, has been found to reduce the subsequent risk for breast cancer in female offspring. As this pro- tective effect could be due to exposure to preeclampsia-specific proteins during intrauterine life, the proteomic profiles of umbilical cord blood plasma between preeclamptic and normotensive pregnancies were compared. Umbilical cord plasma samples, depleted of 14 abundant proteins, were subjected to proteomic analysis using the quantitative method of nanoACQUITY ultra performance liquid chromatography-mass spectrometry with elevated energy mode of acquisitionE （NanoUPLC-MSE）. Sixty-nine differentially expressed proteins were identified, of which 15 and 6 proteins were only detected in preeclamptic and normotensive pregnancies, respectively.Additionally, expression of 8 proteins （gelsolin, complement C5, keratin type I cytoskeletal 10, pigment epithelium-derived factor, complement factor B, complement component C7, hemoglobin subunit gamma-2 and alpha-fetoprotein） were up-regulated in preeclampsia with a fold change of 1〉 2.0 when compared to normotensive pregnancies. The identification of alpha-fetoprotein in pre- eclamptic umbilical cord blood plasma supported the validity of this screen as alpha-fetoprotein has anti-estrogenic properties and has previously been linked to preeclampsia as well as a reduced breast cancer risk. The findings of this pilot study may provide new insights into the mechanistic link between preeclampsia and potentially reduced breast cancer susceptibility in adult life.
