研究目的: |
(1)利用单细胞测序技术,对比斜视复发二次术后粘连的眼外肌组织与第一次斜视手术正常眼外肌组织的转录组学差异。 (2)在人体组织水平验证 Piezo1/YAP 信号通路在眼外肌纤维化中的表达情况,确立力学调控的关键靶点。2:确立并阻断“力学-纤维化”恶性循环:科学假说验证:证明斜视术后粘连不仅仅是炎症问题,更是一个力学启动的过程。验证通路:瘢痕变硬/机械牵拉 → Piezo1 激活 → Ca2? 内流 → Integrin β1 激活 → YAP 核转位 → 纤维化加重。机制阐明:揭示 Piezo1 作为核心力学传感器在术后粘连中的作用, |

|
Objectives of Study: |
(1) Utilize single-cell sequencing technology to compare the transcriptomic differences between the extraocular muscle tissues of eyes with recurrence of strabismus after the second surgery and the normal extraocular muscle tissues from the first strabismus surgery.(2) Verify the expression of the Piezo1/YAP signaling pathway at the level of human tissues to establish the key target for mechanical regulation. 2: Establish and block the "mechanical-fibrosis" vicious cycle: Scientific hypothesis verification: Prove that post-strabismus adhesion is not only an inflammatory issue, but also a process initiated by mechanics. Verification pathway: Scar hardening/ mechanical traction → Piezo1 activation → Ca2? influx → Integrin β1 activation → YAP nuclear translocation → Fibrosis aggravation. Mechanism clarification: Reveal the role of Piezo1 as the core mechanical sensor in post-operative adhesion. |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
文章发表后,经过去标识化处理的单细胞转录组测序数据将上传至国家基因组科学数据中心(NGDC-GSA)或同类公共数据库。其他临床原始数据将在文章发表6个月后,向主要研究者(PI)提出合理申请并获批后共享。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
De-identified single-cell transcriptomic sequencing data will be deposited in the National Genomics Data Center (NGDC-GSA) or similar public repositories upon publication. Other raw clinical data will be available 6 months after publication upon reasonable request to the Principal Investigator (PI). |
|
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: |
本研究采用纸质病例报告表(CRF)记录源数据,随后双人核对录入电子数据采集系统(EDC)。单细胞测序原始数据存储于本地生物信息学专用数据库,并进行定期备份。主要研究者定期进行源数据核查(SDV)和逻辑核查,确保数据的准确性与完整性。所有数据均采用去标识化编码管理,密钥由PI单独保存。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Paper Case Report Forms (CRF) will be used to record source data, followed by double-entry into an Electronic Data Capture (EDC) system. Raw single-cell sequencing data will be stored in a dedicated local bioinformatics database with regular backups. The Principal Investigator will perform periodic Source Data Verification (SDV) and logic checks to ensure data accuracy and integrity. All data will be managed using de-identified codes, with the key held solely by the PI. |
