脑血管疾病患者血清神经元特异性烯醇化酶水平变化及临床意义

To explore the application of NSE in the serum in the diagnosis of the cerebrovascular disease.Methods Serum levels of NSE from 195 patients with cerebrovascular disease and normal controls were detected with ELISA. The blood samples from the patients were acquired within 3 days after the outbreak of cerebrovascular disease and taken again after 2 weeks from 148 of all cases. The result of detecting of NSE was analysed in comparison with and the level of NSE in the CSF. Result There was significance difference between the level of NSE in the serum of patient with cerebrovascular diseases and that of normal controls when the Analysis of Variance was used to analyze the value of measurement. The same outcome was also got using ANOVA to analyze the different test group with the blood samples were acquired within 3 days. ( F = 24.94, P = 0. 000). But in the other hand, there was no evidently different in the different group made up patients if LSD was put in use instead of the ANOVA.Corelation analysis of NSE concentration was done between the in the blood samples in 3 days and those 2 weeks later (r = 0.884, t = 37.904, p = 0.000), NSE concentration in the blood samples and those in the CSF(r = 0.969, t = 8. 695, p = 0. 000), and the outcome show that there was difference between them.The same comparison between NSE concentration was done between the in the blood samples in 3 days and Head CT(r=O.857,p =O.000),Nerve Function Defect(r=0.848,p=0.000).Concluslon Thelevels of NSE in sera of patients with eerebrovascular disease were positive related with the degree of Cerebral infarction or volume of Hematoma shown by Head CT. Therefore, it would contribute to diagnosis of cerebrovascular disease if the detecting of NSE was applied in clinical laboratory.
