鹿瓜多肽注射液辅助治疗颈椎病的疗效及作用机制探究

目的:探讨鹿瓜多肽注射液辅助治疗颈椎病的疗效及作用机制探究。方法:选取2016年1月～2018年1月在医院就诊的颈椎病患者90例,按随机数表法分为对照组及观察组。两组患者均进行常规康复治疗,观察组在此基础上静脉注射鹿瓜多肽注射液,持续治疗10d,测量两组患者治疗前后颈椎活动度、数字疼痛分级(NPRS)评分、颈部残障指数(NDI)评分,并统计两组患者不良反应发生率。结果:观察组治疗后颈椎活动度均高于对照组(P0.05);观察组治疗后NPRS、NDI评分均低于对照组(P0.05);两组患者治疗期间均未出现严重不良反应。结论:鹿瓜多肽注射液辅助治疗颈椎病可提高颈椎活动度。

山药粗多糖的提取工艺

对鲜山药中水溶性粗多糖的提取工艺进行了研究,通过单因素试验和L9（34）正交试验,研究了料液比、提取温度、时间和乙醇体积分数对粗多糖得率的影响,极差分析及方差分析结果表明提取温度和料液比是影响山药粗多糖提取的主要因素,较优的工艺为料液比1 g：9 mL,温度50 ℃,时间2.5 h,乙醇体积分数75%,在此工艺条件下,鲜山药粗多糖得率为0.2449%（以鲜山药质量计）.     

肝炎后肝硬化并发门脉高压患者载脂蛋白AⅠ及载脂蛋白B100的观察

载脂蛋白是一类结合脂类的水溶性蛋白，其检测多用于心血管疾病的预防、诊断、疗效观察和病因学研究，而对肝实质病变患者载脂蛋白变化的研究还较少。为此，我们对32例肝炎后肝硬化并发门脉高压患者载脂蛋白AⅠ（ApoAⅠ）和载脂蛋白B100（ApoB100）水平进行了检测，并与32例正常人作对照观察，现报告如下。     

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.
