Study phase:

N/A

研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

通过比较创伤脓毒症患者与单纯创伤患者截肢术中获取的坐骨神经标本,观察施万细胞代谢相关分子、琥珀酸代谢、巨噬细胞浸润及SUCNR1表达等变化,探讨施万细胞代谢异常是否通过琥珀酸-SUCNR1信号参与危重症多发性神经病(CIP)的发生发展。  

Objectives of Study:

To compare sciatic nerve specimens obtained during amputation from trauma patients with sepsis and those with trauma alone, and to observe changes in Schwann cell metabolism-related molecules, succinate metabolism, macrophage infiltration, and SUCNR1 expression, so as to investigate whether Schwann cell metabolic abnormalities contribute to the onset and progression of critical illness polyneuropathy (CIP) through the succinate–SUCNR1 signaling pathway.

排除标准:

既往明确存在周围神经系统疾病者,如遗传性周围神经病、慢性炎性脱髓鞘性多发性神经根神经病等; 合并严重中枢神经系统损伤者,如严重颅脑损伤、脊髓损伤等,可能明显影响神经功能判断; 既往存在明确可影响周围神经状态的基础疾病者,如严重糖尿病周围神经病变、长期酗酒所致周围神经病变等; 截肢标本中坐骨神经直接受严重毁损、坏死或污染,无法获取合格研究标本者; 临床资料严重缺失,无法完成主要变量收集者; 患者或法定代理人不同意参加研究,或在研究过程中撤回知情同意者。

Exclusion criteria:

1. Patients with a clearly documented history of peripheral nervous system disorders, such as hereditary peripheral neuropathy or chronic inflammatory demyelinating polyradiculoneuropathy; 2.Patients with severe central nervous system injury, such as severe traumatic brain injury or spinal cord injury, which may significantly affect the assessment of neurological function; 3.Patients with pre-existing diseases known to affect peripheral nerve status, such as severe diabetic peripheral neuropathy or alcohol-related peripheral neuropathy; 4.Patients in whom the sciatic nerve in the amputated specimen is severely damaged, necrotic, or contaminated, making it impossible to obtain a qualified study specimen; 5.Patients with severely incomplete clinical data, making collection of major study variables impossible; 6.Patients or their legally authorized representatives who refuse to participate in the study, or who withdraw informed consent during the course of the study.

本研究采用纸质病例报告表与电子数据库相结合的方式进行数据管理。临床资料来源于医院电子病历系统、检验检查系统、手术麻醉系统及实验室检测结果。所有研究参与者均以唯一研究编号识别,姓名、住院号等直接身份信息不录入分析数据库,仅保存在受限的编号对应表中。研究数据由两名研究人员双录入和核对,完成数据清洗、逻辑检查和异常值核查后锁定数据库。纸质资料统一存放于带锁文件柜中,电子数据采用加密计算机和权限管理方式保存,并定期备份。

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

Clinical data will be collected using paper case report forms and an electronic database. Data sources include the hospital electronic medical record system, laboratory and examination systems, anesthesia and surgical records, and laboratory assay results. Each participant will be assigned a unique study ID, and direct identifiers will not be entered into the analytical database. Data will be entered and cross-checked independently by two researchers, followed by data cleaning, logical consistency checks, and verification of outliers before database lock. Paper records will be stored in locked cabinets, and electronic data will be stored on password-protected computers with access control and regular backup.
