目的:本研究旨在通过对临床可能(可疑)克雅病(CJD)病例及其他神经系统病变患者的150份脑脊液标本进行14-3-3蛋白检测,对其临床意义和临床应用价值进行初步探讨。方法:用Westernblot方法检测脑脊液标本中的14—3—3蛋白。结果:150份标本中共19例阳性,其中临床诊断CJD者(n=6),5例阳性;临床疑似CJD者(n=23),6例阳性;非CJD痴呆者(n=6),1例阳性;单纯疱疹病毒性脑炎(n=7),3例阳性;其他病毒性脑膜脑炎、结核性脑膜脑炎、新型隐球菌脑膜炎、脑梗死各有1例阳性。结论:在临床诊断及疑似CJD病例中,脑脊液14—3—3蛋白检测是重要的实验室诊断手段;脑脊液14—3-3蛋白在CJD的诊断中强调病例的选择性。
Aim:To evaluate clinical significance of 14-3-3 protein detection in diagnosis of Creutzfeldt- Jacob disease(CJD)and other disorders of central nervous system(CNS).Methods:150 cerebrospinal fluid (CSF)samples were detected with Western blot.26 samples of them were from cases with probable CJD (n=6)and possible CJD(n=23),clinically.Results:In all samples,19 samples showed a positive test.In 5 of 6 cases with probable CJD and 6 of 23 possible CJD were positive.Positive test was found in 1 of 6 patients with n...
