研究目的: |
本研究拟采用本土化嗅觉测试(阈值、分辨、识别),对精神分裂症患者的嗅觉功能进行一个较为全面的评估,同时记录患者的临床症状,进一步精细化探索两者之间的关系。借助神经影像学工具fMRI明确精神分裂症嗅觉障碍神经网络异常,为个体化干预提供影像标志。 |

|
Objectives of Study: |
This study aims to conduct a comprehensive assessment of olfactory function in patients with schizophrenia using standardized olfactory tests (threshold, discrimination, and recognition), while simultaneously documenting their clinical symptoms to further refine our understanding of the relationship between the two. By utilizing fMRI, a neuroimaging tool, we will identify abnormalities in the neural networks underlying olfactory dysfunction in schizophrenia, thereby providing imaging biomarkers to inform personalized interventions. |

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: |
数据收集后进行清理,通过人工检查和电脑检查两种方式对数据库进行核查,查找重复或缺失、异常值、逻辑错误问题。一般人口学信息出现以上错误,进行再次问询,修正补充信息;若评价指标出现异常值,则删除该异常值。数据由项目负责人统一管理。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Following data collection, the information undergoes cleansing procedures. The database is verified through both manual and computerised checks to identify duplicates, missing or anomalous values, and logical inconsistencies. Should demographic information exhibit such errors, follow-up inquiries are conducted to rectify and supplement the data. Any abnormal values within evaluation metrics are removed. All data is centrally managed by the project lead. |
