研究目的:

本研究旨在阐明淋巴管系统在疾病状态下的功能变化及其对疾病转归的影响,以急性脑损伤为研究模型,聚焦脑膜淋巴管功能障碍及其临床意义。研究目标包括: 1. 明确脑膜淋巴管的动态变化。 2. 揭示脑膜淋巴功能障碍与脑水肿消退之间的联系。 3. 鉴定CSF中可反映MLVs功能的分子标志物。 4. 构建可用于预警脑水肿延迟恢复风险的多模态联合预测模型。 5. 为后续靶向脑膜淋巴系统的新型治疗策略提供依据。  

Objectives of Study:

This study aims to elucidate the functional alterations of the lymphatic system under disease conditions and their impact on clinical outcomes, using acute brain injury as the disease model and focusing on the dysfunction of meningeal lymphatic vessels (MLVs) and its clinical significance. The research objectives are as follows: (1) To characterize the dynamic changes of meningeal lymphatic vessels; (2) To determine the association between meningeal lymphatic dysfunction and the resolution of cerebral edema; (3) To identify cerebrospinal fluid biomarkers that reflect the function of MLVs; (4) To develop a multimodal predictive model for identifying patients at risk of delayed edema recovery; (5) To provide a basis for future therapeutic strategies targeting the meningeal lymphatic system.

纳入标准:

1.年龄18至80岁,性别不限; 2.入院后48小时内接受常规头颅CT检查,提示存在脑挫裂伤、脑水肿、脑室受压、蛛网膜下腔出血等急性损伤表现; 3.在损伤后1个月内接受头颅MRI检查,且配合加扫脑膜淋巴管显像序列(如3D-FLAIR),图像质量合格; 4.在损伤后3个月内完成MRI随访,同样加扫脑膜淋巴管序列,以观察MLVs的动态变化; 5.临床治疗过程中若需行颅脑手术,且术后安置脑脊液引流管者,可依照临床治疗安排在术后期间多次采集脑脊液,用于检测MLVs调控因子水平; 6.对于因继发性脑积水等原因拟择期行脑室外分流术等手术治疗的患者,术前已完成标准MRI(含脑膜淋巴管序列)评估,术中可在无需增加创伤的情况下留取脑膜组织用于组织学染色; 7.患者本人或法定监护人能理解研究目的与流程,签署研究专用知情同意书,自愿参加,愿意配合完成后续影像随访等。

Exclusion criteria:

1. Age under 18 years, pregnant women, or patients with terminal illnesses; 2. Failure to complete CT evaluation within 48 hours of admission; 3. Presence of severe trauma at other body sites (Abbreviated Injury Scale >= 3); 4. Pre-existing chronic central nervous system diseases (e.g., Alzheimer’s disease, multiple sclerosis); 5. Presence of intracranial infectious diseases; 6. History of major central nervous system structural abnormalities or prior neurosurgery; 7. Immune deficiency or autoimmune disorders; 8. Severe systemic diseases (e.g., heart failure >= New York Heart Association class III, severe hepatic or renal insufficiency); 9. Inability to undergo MRI or presence of MRI contraindications (e.g., metallic implants, severe claustrophobia); 10. Refusal to sign the informed consent form or voluntary withdrawal from the study during the research process.

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

This study will collect clinical information (including medical history, examination results, and outcome data), imaging data (such as MRI and CT), and selected biological samples (cerebrospinal fluid and blood) from patients with acute brain injury. All data and samples will be obtained during routine clinical care, without introducing additional risk. Immediately after collection, all data will be de-identified and assigned a unique code, with personal identifiers such as name and hospital ID removed. Data will be stored in an encrypted database with access restricted to authorized research personnel. The research team will perform regular data quality control and backups to ensure data integrity and security, thereby maximizing the protection of participant privacy and ensuring compliance with research regulations.
