BACKGROUND
Cognitive impairment is one of the primary sequelae affecting the quality of life of patients with Japanese encephalitis (JE). The clinical treatment is mainly focused on life support, lacking of targeted treatment strategy.
METHODS
A cerebrospinal fluid (CSF) proteomic profiling study was performed including 26 patients with JE in Gansu province of China from June 2017 to October 2018 and 33 other concurrent hospitalized patients who were excluded central nervous system (CNS) organic or CNS infection diseases. The clinical and proteomics data of patients with JE were undergoing combined analysis for the first time.
RESULTS
Two subtypes of JE associated with significantly different prognoses were identified. Compared to JE1, the JE2 subtype is associated with lower overall survival rate and a higher risk of cognitive impairment. The percentages of neutrophils (N%), lymphocyte (L%), and monocytes (M%) decreased in JE2 significantly.
CONCLUSIONS
The differences in proteomic landscape between JE subgroups have specificity for the prognosis of cognitive impairment. The data also provided some potential target proteins for treatment of cognitive impairments caused by JE. Trial registration ChiCTR, ChiCTR2000030499.

背景
认知障碍是影响日本脑炎（乙脑）患者生活质量的主要后遗症之一。临床治疗主要集中在生命支持方面，缺乏针对性的治疗策略。
方法
进行了一项脑脊液（CSF）蛋白质组学分析研究，纳入了2017年6月至2018年10月期间中国甘肃省的26例乙脑患者以及33例同期住院的排除中枢神经系统（CNS）器质性疾病或CNS感染性疾病的患者。首次对乙脑患者的临床和蛋白质组学数据进行联合分析。
结果
确定了两种预后明显不同的乙脑亚型。与JE1相比，JE2亚型的总生存率较低，认知障碍风险较高。JE2中中性粒细胞（N%）、淋巴细胞（L%）和单核细胞（M%）的百分比显著降低。
结论
乙脑亚组之间蛋白质组格局的差异对认知障碍的预后具有特异性。这些数据还为治疗乙脑所致认知障碍提供了一些潜在的靶蛋白。试验注册：中国临床试验注册中心，ChiCTR2000030499。于2017年6月1日注册，http://www.medresman.org.cn/pub/cn/proj/projectshow.aspx?proj=6333。
