测量时间点:

RNA-seq后

测量方法:

qRT-PCR验证: 设计YWHAB基因特异性引物。 提取胎盘组织RNA,反转录为cDNA,进行qRT-PCR检测。 数据分析:以GAPDH为内参,计算YWHAB的相对表达量。 免疫组化验证:制备胎盘组织石蜡切片,进行YWHAB抗体染色。显微镜下观察YWHAB蛋白表达水平,比较实验组与对照组的差异。 确认研究对象:综合RNA-seq、qRT-PCR和免疫组化结果,确定YWHAB为研究对

Measure time point of outcome:

After RNA-seq

Measure method:

qRT-PCR validation: Specific primers for the YWHAB gene were designed. RNA was extracted from placental tissues and reverse transcribed into cDNA for qRT-PCR detection. Data analysis: GAPDH was used as an internal reference to calculate the relative expression level of YWHAB. Immunohistochemical validation: Paraffin sections of placental tissues were prepared and stained with YWHAB antibody. The expression level of YWHAB protein was observed under a microscope, and the differences between the ex

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 目标:收集患者基本信息、按流程获取胎盘组织进行试验。 方法:使用医院电子病历系统,由医务人员在随访时录入数据。 质量控制:双人录入,系统自动校验逻辑错误,定期核查纸质记录与电子数据一致性。 数据管理 存储:数据存储于加密的云端数据库,每日自动备份。 编码:采用CDISC标准编码,确保数据在内部可共享和分析。 安全:仅授权人员可访问数据,操作记录实时审计。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data Collection Objective: Collect patient basic information and obtain placental tissue for experiments following the process. Method: Use the hospital's electronic medical record system, with medical staff entering data during follow-up visits. Quality Control: Double-entry, with the system automatically verifying logical errors, and regular verification of the consistency between paper records and electronic data. Data Management Storage: Data is stored in an encrypted cloud database and automatically backed up daily. Coding: Follow the CDISC standard for coding to ensure data can be shared and analyzed internally. Security: Only authorized personnel can access the data, and operation records are subject to real-time auditing.
