背景情况:
- 创伤性脑损伤 (TBI) 是一个重大的全球健康挑战,导致长期的神经问题和系统性并发症.
- 虽然动物模型表明TBI和肠道微生物群之间的联系,但人类数据,特别是在急性阶段,是有限的.
研究的目的:
- 为了研究最近因TBI住院的患者的肠道微生物组成和功能.
- 探索肠道微生物群变化与TBI患者临床参数之间的关系.
主要方法:

Athletes absorb several hundred mild traumatic brain injuries (mTBI)/concussions every year; however, the consequence of these on the brain is poorly understood. Therefore, an animal model of single and repetitive mTBI that consistently replicates clinically relevant symptoms provides the means to advance the study of mTBI and...

Lateral fluid percussion (LFP), an established model of traumatic brain injury in mice, is demonstrated. LFP fulfills three major criteria for animal models: validity, reliability and clinical relevance. The procedure, consisting of surgical craniotomy, fixation of hub followed by induction of injury, resulting in focal and diffuse injuries, is...

This paper describes a novel model of primary blast traumatic brain injury. A compressed-air driven shock tube is used to expose in vitro mouse hippocampal slice cultures to a single shock wave. This is a simple and rapid protocol generating a reproducible brain tissue injury with a high throughput.
