Efficacy of butylphthalide in the treatment of patients with stroke attributed to intracranial arterial stenosis
Bibliographic record
Abstract
Objective: To explore the clinical efficacy of butylphthalide in treating patients with stroke attributed to intracranial artery stenosis (ICAS). Methods: In this retrospective study, records of 163 patients with stroke attributed to ICAS admitted to Jiaxing Second Hospital from January 2021 to January 2023 were retrospectively analyzed. Patients were divided into two groups based on the treatment received: control group (patients received routine treatment, n=55) and observation group (patients treated with butylphthalide on a routine basis, n=58). Changes in levels of cerebrovascular reactivity (CVR), breath-holding index (BHI), pulsatility index (PI), and middle cerebral artery mean flow velocity (Vm) between the two groups before and after treatment were compared. In addition, cognitive function, neurological function, and living ability were compared between the two groups before and after treatment, as well as the overall clinical efficacy of the treatment. Results: The baseline data was comparable between the two groups (P>0.05). After the treatment, CVR, BHI, and Vm indicators in the observation group were significantly higher than those in the control group, while the levels of PI indexes were significantly lower than those in the control group (P<0.05). Montreal Cognitive Assessment (MoCA) and Barthel scale scores of the observation group were significantly higher compared to the control group, while the scores of National Institutes of Health Stroke Scale (NIHSS) were significantly lower (P<0.05). Conclusions: Butylphthalide in addition to routine treatment can effectively improve cerebrovascular reserve function, promote neurological and cognitive dysfunction recovery, and enhance daily living ability of patients with stroke caused by ICAS. doi: https://doi.org/10.12669/pjms.40.9.10100 How to cite this: Lu X, Qian S, Wang Y, Zhang X, Jin Y, Yu B.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
