In order to determine the abnormal cerebral metabolism in the pathological state, we compared the blood of internal jugular vein, superior vena cava and radial artery during central venous catheterization. Metabonomics, proteomics and inflammatory factor microarray were used to detect the material differences in arteriovenous blood of patients with disorders of consciousness. At the same time, we concurrently compared it with the peripheral plasma metabolome of two additional patient cohorts: those in-stent restenosis and non-restenosis.

Background:It is unclear what substances the brain needs to ingest for its activity under pathological conditions

Method:The uptake and release of substances by the brain were observed by comparing arterial blood with internal jugular vein blood;The characteristics of brain metabolites were observed by comparing internal jugular vein blood with superior vena cava blood. Compared it with the peripheral plasma metabolome of two additional patient cohorts: those in-stent restenosis and non-restenosis.

Objective:By analyzing different substances, this paper briefly describes the pathological mechanism of patients with disorders of consciousness, and looks for potential prognostic biomarkers.

Inclusion Criteria:

1.Patients with consciousness disorder caused by various severe brain injuries

Exclusion Criteria:

1. Patients who have been judged brain dead
2. There are persistent epileptic activity, inhibition or seizure inhibition patterns
3. Recent fever, abnormal liver and kidney function
