Abstract
Objective To investigate the duration of glutamate increase in patients with stable and progressing ischaemic stroke and determine the time window for treatment with inhibitors of glutamate release or glutamate receptor antagonists. Methods A total of 128 patients with acute cerebral infarction admitted consecutively between September 1996 and December 2001 were involved in the study. Glutamate concentrations in plasma and cerebrospinal fluid (CSF) were analyzed by high-performance liquid chromatography (HPLC) in patients and control subjects. At the same time, Canadian Stroke Scale (CSS) score and cerebral infarction volume (CTV) were also tested. Results Mean glutamate concentrations in plasma (P0.01) and CSF (P0.001) of the patients were significantly higher than in controls. Mean glutamate concentrations in plasma and CSF in 50 patients with progressing ischaemic stroke were significantly higher (P0.01) than in 78 patients with stable ischaemic stroke. Mean glutamate concentrations in plasma and CSF in patients with CTV≥10 cm3 were significantly higher (P0.05) than in those with CTV10 cm3, and glutamate concentrations in CSF of 50 patients with progressing ischaemic stroke evidently correlated with the CTV values (r= 0.303, P 0.05). Conclusion Our findings suggest that a wide window of preventing neurological deterioration in patients with acute ischaemic stroke exists with the use of glutamate antagonists. The CSF glutamate content may serve as an index to judge the progression of ischaemic brain injury and use of glutamate release inhibitors.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
