Conditions
Summary
This is a single-center, prospective, randomized, open-label, blinded-endpoint exploratory clinical study enrolling 46 patients with acute ischemic stroke. All eligible patients have symptom onset within 4.5 hours, meet intravenous thrombolysis indications, and receive standard thrombolysis and routine stroke treatment. Participants are randomly assigned to two groups: the intervention group receives early intravenous infusion of 10% fructose injection plus standard treatment, while the control group receives only standard treatment without fructose. The study mainly evaluates changes in neurological function via NIHSS scores within 7 days after thrombolysis, assesses cerebral infarct lesion volume and brain edema using multimodal MRI including DWI, T2WI and MRS, detects cerebral neuronal metabolic markers, and conducts 1-month follow-up of neurological function by NIHSS score as well as functional prognosis using the mRS score. The research also comprehensively monitors adverse events and safety indicators to explore the clinical efficacy, neuronal metabolic regulation effect and safety of early fructose injection combined with intravenous thrombolysis in acute ischemic stroke patients, aiming to provide clinical evidence for early neuroprotective intervention.
Eligibility
Inclusion Criteria6

- Time from stroke onset to hospital admission ≤ 4.5 hours, with new ischemic lesions confirmed by emergency multimodal cranial MRI (DWI/T2WI).
- Meeting the indications for intravenous thrombolysis, without absolute contraindications to thrombolysis, and planned to receive standard intravenous thrombolysis.
- Relatively stable vital signs, able to complete baseline and follow-up cranial MRI examinations including DWI, T2WI and ¹H-MRS, as well as NIHSS and mRS scale assessments.
- The patient or legal representative voluntarily participates in the study and signs written informed consent.
Exclusion Criteria23

- Suspected intracranial hemorrhage or aneurysmal subarachnoid hemorrhage;
- Tumors with increased bleeding risk;
- Peptic ulcer disease, esophageal varices, aneurysm, arterial/venous malformation within the past 3 months;
- Any other known diseases associated with significantly elevated bleeding risk.
- Pre-stroke mRS score ≥ 2, combined with dementia or other neurological disabling diseases.
- Complicated with severe medical history affecting endpoint evaluation and follow-up, such as craniocerebral trauma, multiple sclerosis, encephalitis, tumor, poisoning, syphilis, or severe cardiac, pulmonary, hepatic, renal and endocrine diseases.
- Pregnant females.
- Currently participating in another investigational drug or device study, or participation in other experimental treatment within less than 30 days prior to enrollment.

Interventions
Single intravenous infusion of 250 mL 10% fructose injection administered as early as possible within the ischemic stage, combined with standard intravenous thrombolysis and standardized basic treatment for acute ischemic stroke. Unified blood pressure and blood glucose management are implemented, and antiplatelet therapy is started 24 hours after thrombolysis.
