药物成份或治疗方案详述:

拟招募150例受试者(MCI组、AD组、正常认知组各50例),标准问卷调查收集患者一般临床资料,收集血生化实验室指标、影像资料(头颅磁共振)。受试者入组后采集血样,质谱法检测血浆Aβ、血浆糖蛋白等血液标志物;提取DNA,进行AD基因检测;留存血样;部分AD组受试者留取脑脊液样本、进行AD脑脊液生物标志物检测;进行认知神经电生理检查,包括情景记忆任务、新异Oddball任务Go/NoGo任务。入组后第1年+15天进行首次随访,询问病史、体格检查、认知量表测评。入组后第2年+15天进行终点事件访视,询问病史,体格检查,认知量表测评,终点事件判定,结局评价。转化为AD的受试者,采集血样,检测血浆Aβ、血浆糖蛋白等血液标志物,部分受试者留取脑脊液样本、检测脑脊液生物标志物。 

Description for medicine or protocol of treatment in detail:

150 subjects (50 in MCI group, 50 in AD group and 50 in normal cognitive group) were recruited. General clinical data, biochemical laboratory indexes and imaging data (brain MRI) were collected by standard questionnaire. Blood samples were collected after the subjects were enrolled, and plasma a was detected by mass spectrometry β Plasma glycoprotein and other blood markers; DNA was extracted to detect ad gene; Blood samples were kept; CSF samples were collected from some subjects in AD group for detection of biomarkers in CSF; Cognitive neurophysiological tests were performed, including episodic memory task, novelty oddball task and go / NoGo task. The patients were followed up for the first time in the first year and 15 days after admission. The medical history, physical examination and cognitive scale were asked. In the second year + 15 days after admission, the end-point visit, medical history, physical examination, cognitive scale evaluation, end-point event judgment and outcome evaluation were conducted. Blood samples were collected from AD patients to detect plasma a β Plasma glycoprotein and other blood markers, part of the subjects took cerebrospinal fluid samples to detect cerebrospinal fluid biomarkers.
