急性脑卒中患者血清神经元特异性烯醇化酶、S-100B蛋白、髓鞘碱性蛋白水平的变化 总被引:4,自引:1,他引:4
目的探讨急性脑卒中患者血清神经元特异性烯醇化酶(NSE)、S-100B蛋白、髓鞘碱性蛋白(MBP)水平变化及其临床意义。方法回顾性对照分析发病在48 h内的45例急性脑卒中患者(其中脑梗死组19例,脑出血组15例,短暂性脑缺血发作组11例)血清NSE、S-100B蛋白、MBP水平变化及其与脑梗死、脑出血患者神经功能缺损程度的相关性。结果脑梗死组和脑出血组患者血清NSE、S-100B蛋白、MBP水平均较对照组有不同程度增高(P<0.05),而短暂性脑缺血发作组与正常对照组比较均无明显变化。脑梗死组和脑出血组患者中神经功能缺损较重的中重型亚组患者血清NSE、S-100B蛋白、MBP水平较轻型亚组水平高(P<0.05)。结论血清NSE、S-100B蛋白、MBP水平可作为急性脑卒中患者病情判断、预后评估的指标之一,对早期脑梗死与短暂性脑缺血发作也有鉴别诊断价值,尤其适用于无法进行影像学检查的脑卒中患者。 相似文献

BACKGROUND: The plasma level of neuron specific enolase (NSE) can be used to diagnose and evaluate neuronal injury and predict early prognosis.
OBJECTIVE: To observe the dynamic changes in plasma levels of NSE in patients with acute cerebral infarction, and to investigate its correlations with disease severity and prognosis.
DESIGN, TIME AND SETTING: This non-randomized, concurrent case-control experiment was performed at the Department of Neurology, First Hospital Affiliated to Heilongjiang University of Traditional Chinese Medicine between May and July 2007. PARTICIPANTS: Eighteen patients with acute cerebral infarction, who received treatment at the Department of Neurology, First Hospital Affiliated to Heilongjiang University of Traditional Chinese Medicine between May and July 2007, were recruited into the patient group. An additional 10 healthy individuals, who received health examinations simultaneously, were included as controls.
METHODS: Following admission (within 3 days) and at days 6, 12, and 30 subsequent to acute cerebral infarction attack, 3 mL venous blood was taken from each patient before the morning meal to determine the plasma level of NSE by enzyme-labeled immunosorbent assay. One-time blood extraction was performed in each healthy subject during the health examination for the same purpose as in patients. At 6 and 30 days following acute cerebral infarction attack, CT examination was performed for calculation of cerebral infarction volume according to the Tada formula. Following admission and at 30 days of disease invasion, all patients were scored by the National Institutes of Health Stroke Scale (NIHSS, 13 items).
MAIN OUTCOME MEASURES: Comparison of NSE plasma level between acute cerebral infarction patients and healthy individuals; correlations of NSE plasma level in acute cerebral infarction patients with cerebral infarction volume, NIHSS score, and prognosis.
RESULTS: Following admission and at days 6 and 12 of disease invasion, the plasma level of NSE was significantly higher in the patient group than in the control group (P 〈 0.05). Following admission and at day 30 of disease invasion, the NIHSS scores of the patient group were 17.706 and 11.222, respectively. Following admission and at day 6 of disease invasion, the plasma level of NSE was positively correlated with cerebral infarction volume (r = 0.503, 0.435, P 〈 0.05), but it was negatively correlated with NIHSS score (r = -0.571, 0.368, P 〈 0.05). The plasma level of NSE was mostly correlated with cerebral infarction volume, followed by NIHSS score, and lastly prognosis, with regression coefficients of 0.386, 0.343, and 0.340, respectively.
CONCLUSION: The plasma level of NSE is higher in patients with acute cerebral infarction than in the healthy population. It can reflect infarct severity and predict early prognosis of acute cerebral infarction. 相似文献

Prediction of early clinical severity and extent of neuronal damage in anterior-circulation infarction using the initial serum neuron-specific enolase level 总被引:20,自引:0,他引:20
CONTEXT: Prompt and precise measurement of neuronal damage in acute cerebral infarction is important to determine the prognosis of functional outcome. A feasible biochemical marker such as the neuron-specific enolase (NSE) level has been used to detect various diseases involving the central nervous system. OBJECTIVE: To determine whether the initial serum NSE level is a useful marker for predicting the severity of clinical neurological deficits and the extent of neuronal damage in acute anterior-circulation infarction. DESIGN: Case-control study with biochemical-clinicoradiological correlation. SETTING: Tertiary care center. PARTICIPANTS: Eighty-one patients and 77 age- and sex-matched control subjects. MAIN OUTCOME MEASURES: Patients with anterior-circulation infarction underwent intravenous serum NSE sampling within 24 hours after symptom onset. Recent infarction was confirmed by T2-weighted and diffusion-weighted magnetic resonance imaging of the brain about 1 week after the onset of stroke. Volumetric analysis of infarction was also performed. The National Institutes of Health Stroke Scale score was measured on admission to the hospital and 1 week after symptom onset. RESULTS: The patients' initial serum NSE levels were statistically significantly higher than the controls (P<.05). The initial serum NSE level highly correlated with the volume of infarction seen on T2-weighted magnetic resonance imaging of the brain (r = 0.62, P<.001) and with the National Institutes of Health Stroke Scale score obtained on hospital admission (r = 0.42, P =.002) and on the seventh day after the onset of stroke (r = 0.44, P<.001). CONCLUSION: The initial serum NSE level is a reliable predictor for the extent of neuronal damage and the severity of clinical neurological deficits in acute anterior-circulation infarction. 相似文献

The purpose of this study was to compare stroke severity, risk factors, and prognosis in patients with intracerebral hemorrhage versus infarction. We prospectively studied 1,000 unselected patients with acute stroke of a verified type in the Copenhagen Stroke Study. Neurological deficits and functional disabilities were evaluated weekly from the time of acute admission throughout the rehabilitation period. Eighty-eight (9%) had intracerebral hemorrhage. The relative frequency of intracerebral hemorrhage rose exponentially with increasing stroke severity. In multivariate analyses, stroke type had no influence on mortality, neurological outcome, functional outcome, or the time course of recovery. Initial stroke severity was the all-important prognostic factor. The relative importance of hypertension and blood pressure on admission was not greater for intracerebral hemorrhage than for infarction. No preponderance was found between type of stroke and sex, age, and smoking. Diabetes, ischemic heart disease, and elevated serum total cholesterol level all favored cerebral infarction as opposed to intracerebral hemorrhage. We conclude that the type of stroke per se has no influence on stroke prognosis in general; the extent of the injury is decisive. The poorer prognosis in patients with intracerebral hemorrhage is due to the increase in frequency of intracerebral hemorrhage with increasing stroke severity. The likelihood of cerebral infarction occuring as opposed to intracerebral hemorrhage seems increased fivefold in stroke patients with diabetes. Hypertension and blood pressure on admission were not predictors of stroke type. 相似文献
