研究目的: |
1. 主要目的:对于入选的住院病人按目前二级卒中预防相关“指南”进行“标准”抗血小板治疗前和治疗后第3、7天、随访第30、90天内的ADP诱导的血小板聚集率、人血浆C4BPα浓度、 外周血白细胞mARC1的mRNA表达水平和ABCC3-013(剪接变异体)的mRNA表达水平的改变与病人在抗血小板治疗后的主要和次要临床终点(endpoints)指标(见疗效评价部分)的关系,以期探明各生物标志物在预测氯吡格雷抵抗中的相对效能; 2. 次要目的:抽取病人的血标本、提取其DNA样本,进行CYP2C19基因分型,验证并评价由多个新、旧生物标志物组成的预测氯吡格雷抵抗的标志物“panel”的预测效能与临床应用价值。 |

|
Objectives of Study: |
1. Main objective: To investigate the relationship between the changes in ADP induced platelet aggregation rate, human plasma C4BPα concentration, mRNA expression levels of mARC1 and ABCC3-013 (splicing variant) in peripheral blood leukocytes, and the changes in the mRNA expression levels of ABCC3-013 (splicing variant) in selected hospitalized patients before and on the 3rd and 7th day after antiplatelet therapy, as well as on the 30th and 90th day after follow-up, in accordance with the current guidelines for secondary stroke prevention, and to explore the relative efficacy of each biomarker in predicting clopidogrel resistance; 2. Secondary objective: To collect blood samples from patients, extract their DNA samples, perform CYP2C19 genotyping, validate and evaluate the predictive efficacy and clinical application value of a biomarker "panel" composed of multiple new and old biomarkers for predicting clopidogrel resistance. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据采集:在经过患者同意后由参与临床研究的医师通过专门临床病例表进行采集。 数据管理:本研究中的所有数据均妥善保管,确保安全无丢失及泄露。不随意上传敏感信息及患者信息至公共平台。数据处理过程中,将患者的个人信息去敏感处理,并使用患者识别码表替代患者姓名及ID。如需技术服务,确保数据相应加密处理,并签订保密协议。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection: After obtaining the patient's consent, physicians participating in the clinical study will collect data through a specialized clinical case table. Data management: All data in this study are properly stored to ensure security and prevent loss or leakage. Do not upload sensitive information and patient information to public platforms at will. During the data processing, the patient's personal information is anonymized and a patient identification code table is used instead of the patient's name and ID. If technical services are required, ensure that the data is encrypted accordingly and sign a confidentiality agreement. |
