目的 :研究乙脑后残疾。方法 :为有对照的历史性队列研究 ,首先以血清学检查阳性者 (165例 )为乙脑组 ,阴性者 (175例 )为非乙脑组 ,比较其在性别、年龄、地域、诊断、预后、疫苗接种和住院天数等方面的差别。其次远期随访了其中的 66例 (3 0∶3 6) ,另设正常健康人对照组 (65例 ) ,以双盲法进行神经系统检查和神经心理测验 ,比较其在后遗症方面的区别。结果 :乙脑组病例来自郊区较多 ,病情程度和早期后遗症重于非乙脑组。后遗症中中枢神经系统症状体征和神经心理测验异常以乙脑组为多 ,而两个对照组则无。结论 :乙脑的后遗症尤其是认知功能损害相当严重
Objective: To study the posterior cerebral etiology. Methods: In a controlled historical cohort study, seropositive patients (n = 165) were enrolled in this study. The negative (175) non-encephalitis patients were enrolled in this study. Their gender, age, location, diagnosis, Prognosis, vaccination and hospital days and so on. Follow-up followed by 66 cases (3 0:36), another normal healthy control group (65 cases), double-blind method of neurological examination and neuropsychological tests, the difference in the sequelae. Results: The patients in JE group were more from the suburbs, and their severity and early sequelae were more than those in non-JE group. Sequelae of central nervous system symptoms and signs and neuropsychological abnormalities in JE group as much, while the two control groups without. Conclusion: The sequelae of JE, especially cognitive impairment, are quite serious
