Study type | Observational |
Following severe traumatic brain injury, patients may remain unconscious for many years. It is the intestinal microbiome and metabolomics analysis comparing differentially intestinal microflora and metabolites between patients with chronic disorder of consciousness and controls so far. The investigators have mature data analysis technology. The obtained results provide new insight into understanding the molecular mechanisms underlying the chronic disorder of consciousness

Eligibility | Inclusion Criteria: 1. Patients ages 18 to 80 years old; 2. Patients had a history of severe Traumatic brain injury (TBI); 3. Patients had awakened from a coma (indicating preserved sleep-wake cycles), including vegetative state and minimally consciousness state; 4. Patients stay unconscious for more than 1 month. Exclusion Criteria: 1. Patients with disorders of consciousness caused by other inducements; 2. Other neurological or psychiatric conditions prior to the current brain injury; 3. Persistent seizure-like activity, inhibition or seizure inhibition; 4. The patients had taken a sedative barbiturate neuroleptics or antidepressants within one month; 5. The clinical state is unstable, and there are signs of spontaneous recovery or deterioration within 1 week; 6. The patients have taken gastrointestinal motility drugs or other drugs affecting gastrointestinal motility in the past month; 7. Had taken antibiotics and probiotics in the past month; 8. Patients with intestinal diseases such as colon cancer, ulcerative colitis or crohn's disease; 9. Patients with acute infectious diseases or liver dysfunction |

Primary | metabolic profiling and Intestinal microbial spectrum | A comprehensive metabolic profile from plasma was obtained with targeted metabolomics analysis and untargeted and targeted lipidomics analysis; intestinal microbial spectrum was obetained from fecal by16S rRNA gene sequencing among HCs, EMCS, MCS and VS groups. | 1 month | |
Secondary | Coma Recovery Scale-Revised(CRS-R) | Coma Recovery Scale-Revised (CRS-R) score was used to quantify the severity, which consists of 23 hierarchically arranged items that comprise six subscales addressing auditory, visual, motor, oromotor/verbal, communication, and arousal processes. The lowest item on each subscale represents reflexive activity, whereas the highest items represent cognitively mediated behaviors In total, The lowest mark on the scale is 0 and the highest mark is 23. To a certain extent, the higher the score is, the better the level of consciousness is, whereas the lower the level of consciousness is. | 30 minutes before samples collection | |
Secondary | Glasgow Outcome Scale (GOS) | A GOS value of <3 was considered as a bad recovery, while a GOS value of =3 was considered as a good recovery. | 6 months | |
Secondary | Indicators of brain connectivity by EEG | Phase locking value (PLV) | On the same day as collecting the samples |
