Dotlike Hemosiderin Spots Are Associated With Past Hemorrhagic Strokes in Patients With Lacunar Infarcts

BACKGROUND AND PURPOSE: Dotlike hemosiderin spots ongradient-echo T2(*)-weighted magnetic resonance imaging of the brain have been histologically diagnosed as old microbleeds associated with small vessel disease (SVD). The authors hypothesize that the presence of many dotHSs may be correlated with the fragility of small vessels and the recurrence of SVD, including lacunar infarction and deep intracerebral hemorrhage (ICH). METHODS: To investigate how dotHSs are related to past history of SVD, the number of subcortical or deep dotHSs was investigated in 146 patients with lacunar infarctions (95 men, 51 women, age 38 to 90 [66.6+/-9.4] years). They were divided into 2 subgroups according to history of deep ICHs or lacunar infarctions. The odds ratio (OR) for past history was estimated from logistic regression analyses with the number of subcortical or deep dotHSs as well as other factors. RESULTS: Of 146 patients with lacunar infarctions, 11 had past symptomatic ICHs and 19 had past symptomatic lacunar infarctions. An elevated rate of history of ICH was found for lacunar infarction patients with many deep dotHSs (>or=3; OR, 9.1; 95% confidence interval, 1.6-51, P=.015). However, history of lacunar infarction was not significantly associated with the number of subcortical or deep dotHSs. CONCLUSIONS: Our findings suggest that many deep dotHSs on T2(*)-weighted magnetic resonance imaging may be correlated with deep ICH-lacunar infarction type of SVD recurrence but not lacunar infarction-lacunar infarction type.     

Assessment of myocardial viability in rats: Evaluation of a new method using superparamagnetic iron oxide nanoparticles and Gd-DOTA at high magnetic field.

The aim of this study was to detect salvageable peri-infarction myocardium by MRI in rats after infarction, using with a double contrast agent (CA) protocol at 7 Tesla. Intravascular superparamagnetic iron oxide (SPIO) nanoparticles and an extracellular paramagnetic CA (Gd-DOTA) were used to characterize the peri-infarction zone, which may recover function after reperfusion occurs. Infarcted areas measured from T1-weighted (T1-w) images post Gd-DOTA administration were overestimated compared to histological TTC staining (52% +/- 3% of LV surface area vs. 40% +/- 3%, P=0.03) or to T2-w images post SPIO administration (41% +/- 4%, P=0.04), whereas areas measured from T2-w images post SPIO administration were not significantly different from those measured histologically (P=0.7). Viable and nonviable myocardium portions of ischemically injured myocardium were enhanced after diffusive Gd-DOTA injection. The subsequent injection of vascular SPIO nanoparticles enables the discrimination of viable peri-infarction regions by specifically altering the signal of the still-vascularized myocardium.     

缺血性脑血管病患者血清基质金属蛋白酶水平及影响因素分析

目的 比较急性脑梗死、短暂脑缺血发作(TIA)和陈旧脑梗死患者血清基质金属蛋白酶-9(MMP-9)水平并分析其影响因素.方法 缺血性脑血管病患者136例,分为急性脑梗死组57例,TIA组22例,陈旧脑梗死组57例,进行神经功能评分及血压、血常规、血脂、血糖检查.依据ELISA法进行血MMP-9测定.结果 MMP-9水平分别为急性脑梗死患者(444.13±418.46)ng/ml,TIA患者(374.36±278.31)ng/ml,陈旧脑梗死患者(231.11±367.43)ng/ml.急性脑梗死和TIA患者血MMP-9水平明显高于陈旧脑梗死患者(P＜0.05).MMP-9水平与血白细胞水平(r=0.192,P=0.025)、低密度脂蛋白(r=0.261,P=0.002)、收缩压(r=0.232,P=0.006)呈正相关;与高密度脂蛋白(r=-0.219,P=0.011)和血糖(r=-0.254,P=0.003)呈负相关.MMP-9与收缩压(β=0.259,P=0.001)、血白细胞(β=0.209,P=0.008)、低密度脂蛋白(β=0.586,P=0.000)、胆固醇(β=-0.458,P=0.007)和血糖(β=-0.200,P=0.014)具有线性关系.结论 MMP-9水平在急性脑梗死及TIA时升高,收缩压、血白细胞和低密度脂蛋白均可能为其影响因素.
