早发型子痫前期应用低分子肝素期待治疗的临床效果分析

目的分析早发型子痫前期应用低分子肝素期待治疗的临床效果。方法回顾分析2017-01—2018-12间在郑州大学第一附属医院产科终止妊娠的95例早发型子痫前期患者的临床资料。按终止妊娠前是否应用低分子肝素分为2组。对照组(47例)给予降压、解痉等治疗;观察组(48例)在对照组基础上加用低分子肝素。结果2组分娩孕周、妊娠延长时间、妊娠并发症发生率、新生儿出生体质量、新生儿窒息及胎儿宫内窘迫发生率、新生儿Apgar评分等,差异均无统计学意义(P>0.05)。结论对早发型子痫前期患者在常规治疗基础上短期应用低分子肝素,不能延长妊娠时间,不改善母婴结局。

Clearance of beta- amyloid from the CSF by the choroid plexus： implications in drug development for treatment of Alzheimer＇s disease

The formation of insoluble aggregates of beta - amyloid peptide （ A ） within the brain extracellular fluid is a critical event in the etiology of Alzheimer＇s disease （AD）. In theory, an unbalanced A kinetics can be due to its over production, inadequate metabolic cleaning, or an improper balance of import or export of A or related molecules at brain barriers. We investigated the role of the choroid plexus, which forms a barrier between blood and brain cerebrospinal fluid （ CSF）, in regulating A in the CSF. A uptake from CSF was determined as its volume of distribution （ VD ） into isola- ted rat choroid plexus tissue by using [^125I] A 1-40 and along with a extracellular space marker [^14C ] sucrose. The choroid plexus exhibited a definite capacity in sequestering [^125I] A 1-40 from the surrounding CSF. Uptake of [^125I] A by the choroid plexus was saturable, time - and temperature - dependent, and not ttffected by addition of transthyretin or apolipoprotein E3. Studies with cultured monolayers of primary choroid epithelial cells indicated that A permeability across cells, corrected by [ ^14C] sucrose, was greater from the CSF -facing membrane than from the blood -facing membrane. Similarly, cellular accumulation of [ ^125 I ] A was concentrative from both directions and was greater from the CSF -facing membrane. Quantitative real- time RT- PCR, immunodetection and enzyme activity assays further revealed the presence of several key enzymes involved in A production, e. g. , amyloid precursor protein and beta - secretase, and in A metabolism and alternate processing, e. g. , insulin degrading enzyme, endothelin - converting enzyme - 1, neprilysin and alpha - secretase. Overall, these results suggest the choroid plexus selectively cleanses A from the CSF by an undetermined mechanism （s） ; moreover, it has the capacity to degrade A , suggesting a vital role of this tissue in maintaining A homeostasis. The perspectives of drug development for treatment of AD by reducing A from brain extracellular fluid as a new strategy will be discussed.

维甲酸调变早幼粒白血病细胞株NB4中G-CSF及其受体表达

目的：进一步研究G－CSF在维甲酸致高白细胞症中的作用。方法：用RT－PCR、Northernblotting方法检测NB4细胞经全反式维甲酸（ATRA）作用后G－CSF mRNA表达的变化，同时用ELISA方法检测细胞培养上清液中G－CSF蛋白水平的变化；采用流式细胞技术检测NB4细胞经ATRA作用后G－CSF受体蛋白表达的变化。结果：ATRA可从基因水平上调NB4细胞中G－CSF表达，并可增加NB4细胞表面G－CSF受体的表达，G－CSF受体表达增加出现的时间虽然稍晚于G－CSF表达增加出现的时间，但仍然在较早期阶段，此时，细胞形态学和NBT实验均证实BN4细胞处于部分分化阶段。结论：在ATRA治疗APL过程中，G－CSF及其受体表达增加可能协同参与了高白细胞症的发生。
