大鼠癫痫持续状态血清C反应蛋白与海马C-FOS蛋白表达的动态观察

<正>C反应蛋白(c-reactive protein,CRP)是体内非特异性炎症反应的敏感标志物之一,正常血清CRP浓度很低,当机体出现炎症或组织损伤时,其浓度可以在数小时内明显升高。尽管许多实验证实CRP与脑卒中、动脉粥样硬化等疾病明显相关,目前尚没有CRP与癫痫关系的正式文献报道。随着对     

氧化应激在阻塞性睡眠呼吸暂停低通气综合征与脑梗死中的作用分析

目的探讨氧化应激在阻塞性睡眠呼吸暂停低通气综合征（OSAHS）通过动脉粥样硬化导致脑梗死发生中的作用。方法按照入选标准选取研究期间住院的脑梗死患者20例、0SAHS患者20例、脑梗死＋OSAHS患者20例作为病例组;在体检中心选取同一时期的健康体检者20名作为对照组。采用双抗体夹心ABC—ELISA法测定15一F2t-异前列烷的表达;采用颈动脉超声测定颈动脉内膜中层厚度（IMT）。结果15-F2t-异前列烷表达和颈动脉内膜厚度在4组间比较时差异有统计学意义（F=214．679,P〈0．001;F=528．334,P〈0．001）。每组内的15-F2t-异前列烷和颈动脉内膜厚度行相关分析示二者呈正相关,以脑梗死＋0SAHS组相关性最为明显（对照组：r=-0．046,P=0．847;脑梗死组：r=0．460,P=0．041;OSAHS组：r=0．482,P=0．032;脑梗死＋OSAHS组：r=0．685,P〈0．001）。结论氧化应激程度与颈动脉内膜增厚呈直线相关,与OSAHS合并脑梗死明显相关,推测OSAHS患者的氧化应激水平增高可通过促进动脉粥样硬化进而导致脑梗死发生。

血清基质金属蛋白酶3与颈动脉粥样硬化斑块及缺血性脑卒中的关系

Objective To investigate the relationship between the matrix metalloproteinase-3(MMP-3)and the stability of carotid artery plaque,and explore MMP-3's prediction role on the attack and relapse of acute ischemic cerebrovascular events.Methods 100 patients with the first ever acute cerebral infarction,100 patients with chronic cerebral circulation insufficiency(CCCI)and 40 persons without cerebrovascular diseases were enrolled in this study.According to the carotid ultrasound examination,100 cerebral infarction patients were divided into three subgroup: unstable plaque group(45 patients,mixed plaque,soft plaque),stable plaque group(35 patients,plaque Group)and endometrial coarse group(25patients).Matrix metalloproteinase-3(MMP-3)levels of all the subjects were measured by enzyme-linked immunosorbent assay(as basal level).All the subjects were followed up for one year to observe cerebral infarction events.Serum MMP-3 levels of each group,and the basic serum MMP-3 levels were compared among patients who were attacked or relapsed cerebral ischemic with those who had not been attack cerebral ischemic during this period of time.Results 5 patients in the cerebral infarction group had relapse (5%),2 patients in the CCCI group were attacked by cerebral ischemic(2%),and no one in the normal control group was attacked by cerebral ischemic.Serum MMP-3 levels in the acute cerebral infarction group were significantly higher than CCCI group,and both groups were significantly higher than normal control group (P ＜0.05).The basic serum MMP-3 levels in all patients who were attacked by cerebral ischemic were significantly higher than those who had not been attack by cerebral ischemic during this period of time(P ＜0.05).The serum MMP-3 levels of the unstable plaque group were significantly higher than stable plaque group.And both groups were significantly higher than endometrial coarse group(P ＜0.05).Conclusions Elevated levels of matrix metalloproteinase-3(MMP-3)might have something with the stability of carotid atherosclerotic plaque,and participate the attack and the relapse of acute cerebral infarction.Determination of MMP-3 might be used to predict the attack and relapse of acute cerebral infarction.

黎月恒教授运用"健脾益胃法"治疗胃癌经验浅析

通过介绍黎月恒教授对脾胃亏虚与胃癌发生关系的理解、提出胃癌的发生与脾胃亏虚密切相关,黎老认为“内虚”是胃癌发生的根本原因,而“本虚标实”是其外在的表现。本虚是以脾胃亏虚为主,脾胃虚弱,机体气机升降失常,水液代谢紊乱,气血津液运化失常,则形成以“气滞、血瘀、湿阻、痰凝、癌毒”等有形病理产物,有形病理产物停滞胃脘,久成癥瘕、积聚。黎月恒教授临床治疗胃癌抓住疾病的根本病机,以“健脾益胃”为根本大法,同时根据患者不同症状临证进行加减,常兼有“理气解郁、祛湿化痰、活血化瘀、软坚散结”等治法,临床疗效甚佳。
