高同型半胱氨酸血症与脑卒中相关性研究

目的探讨血浆同型半胱氨酸(H cy)水平对脑卒中临床亚型、复发及痴呆的影响,并研究高同型半胱氨酸血症(HH)与脑卒中传统危险因素之间的相关性。方法应用酶联免疫吸附试验(EL ISA)检测90例急性脑卒中患者血浆H cy水平。将研究对象分为不同临床亚型,脑白质损伤组与非脑白质损伤组,青年组与老年组,痴呆组与非痴呆组。对不同类型脑卒中患者血浆H cy水平进行比较,对HH脑卒中传统危险因素进行相关与回归分析。结果首次发作(FCS)组血浆H cy水平明显低于复发(RCS)组(P<0.01),HH发生率比较RCS组明显高于FCS组(P<0.05)。痴呆组血浆H cy水平与对照组有差别(P<0.01)。饮酒者血浆H cy含量明显高于不摄入酒精者(P<0.05)。结论HH是脑卒中的独立危险因素,脑卒中患者普遍存在HH,在复发性脑卒中患者中尤其明显。血浆H cy水平随年龄增加而增加,同时HH与血管性痴呆和/或变性性痴呆有关。     

电针治疗血管性痴呆23例临床观察

目的：对电针治疗血管性痴呆的疗效进行临床观察。方法：将45例VD患者按HD8评分不同随机分为电针组和西药尼莫通组。观察二组患者治疗前后HDS、主要症状、ADL及神经功能缺损评分情况。结果：两组治疗后HDS、主要症状、ADL度神经功能缺损评分均有所改善，电针组效果优于西药组（P〈0．01）。结论：电针治疗有助于改善血管性痴呆患者的临床症状度体征。     

丁咯地尔改善血管性痴呆患者记忆能力21例

血管性痴呆(VD)是指由于各种类型的脑血管病所致的痴呆,直接影响脑血管疾病的预后和康复。自2000-05开始,应用丁咯地尔和尼莫地平分别对42例VD患者进行治疗,通过评价韦氏记忆量表(WMS)和日常生活活动能力(ADL)两项评分,结果均差异有非常显著性意义,两组比较,丁咯地尔组对改善VD记忆能力明显优于尼莫地平组。

血管性痴呆危险因素分析

随着社会日益老龄化，老年痴呆疾病的绝对及相对发病率均明显增加。血管性痴呆(vasculer dementia，VD)是老年性痴呆中最常见的病因之一。由于VD是目前惟一可以预防的痴呆，因而其危险因素的确定非常重要。虽然大多数学认为血管性痴呆VD的危险因素与脑卒中的危险因素相同，但目前除年龄因素外，还没有足够的流行病学依据可证明两的危险因素确为一致，因此就VD发病的危险因素作一简要叙述。     

血管性痴呆的危险因素

血管性痴呆(vascular dementia,VD)是老年期痴呆的另一个主要类型,国内外研究结果显示,VD的发病率和患病率均随着年龄的增长而显著增高[1,2],VD占欧美老年期痴呆的15%～20%。亚洲国家如中国和日本VD的发生率较高,     

中医药治疗血管性头痛疗效观察

血管性头痛是临床常见病、多发病，目前现代医学对其发病机理尚不十分明确，大多认为本病的发生与脑血管的收缩、舒张功能异常和生化因素、内分泌因素、精神因素等有关，中医学则认为其发生与“风”、“痰”、“瘀”等有关。作者结合本院神经内科临床的108例血管性头痛患者的治疗，总结如下。     

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.
