AI Article Synopsis
- The study examined the effectiveness of contrast-enhanced ultrasound (CEUS) and superb microvascular imaging (SMI) in assessing blood vessel growth in carotid artery plaques and predicting outcomes for stroke patients.
- Sixty-one patients with carotid atherosclerotic plaques were analyzed using conventional ultrasound, CEUS, and SMI, including a mix of patients who had experienced cerebral infarction and those who had not.
- Results showed that both SMI and CEUS detected higher levels of neovascularization in plaques from patients with cerebral infarction compared to those without, indicating that SMI can effectively indicate neovascularization related to higher stroke risk.
Article Abstract
Objectives: This study aimed to investigate the value of contrast-enhanced ultrasound (CEUS) and superb microvascular imaging (SMI) in evaluating angiogenesis in carotid artery plaques and prognosis in stroke patients.
Methods: Sixty-one patients with carotid atherosclerotic plaques were selected. All patients received conventional ultrasound, CEUS, and SMI examination, including 32 patients with cerebral infarction and 29 patients without cerebral infarction. The results of CEUS and SMI neovascularization of patients were graded 0, 1, and 2 points according to the image characteristics. The consistency between SMI results and CEUS results was evaluated, and the differences in neovascularization in carotid plaques between patients with cerebral infarction and those without cerebral infarction were compared.
Results: SMI showed that the neovascularization score in plaque was 0 point in 13 cases, 1 point in 24 cases, and 2 points in 24 cases. There were no significant differences in age, sex, plaque size, or echo between the two groups. There was no significant difference between the SMI and CEUS results, P > .05. The CEUS neovascularization grade of patients with cerebral infarction had a higher score, which was significantly different from that of patients without cerebral infarction, P < .05. The SMI neovascularization grade of patients with cerebral infarction had a higher score, which was significantly different from that of patients without cerebral infarction, P < .05.
Conclusion: SMI can show neovascularization in plaques, with a significantly higher grade of neovascularization in those of patients with cerebral infarction than in those without cerebral infarction.

Cerebral ischemia-induced pyroptosis contributes to the dissemination of neuroinflammation, and Nod-like receptor protein-3 (NLRP3) inflammasome plays a key role in this process. Previous studies have indicated that Genistein-3'-sodiumsulfonate (GSS) can inhibit neuroinflammation caused by cerebral ischemia, exert cerebroprotective effects, but its specific mechanism has not been comprehensively understood. The aim of this study was to explore the effect of GSS on ischemic stroke-induced cell pyroptosis.

Introduction: The mechanism of remimazolam, a benzodiazepine that activates γ-aminobutyric acid a (GABAa) receptors, in cerebral ischemia/reperfusion (I/R) injury is not well understood. Therefore, we explored whether remimazolam activates protein kinase B (AKT)/glycogen synthase kinase-3β (GSK-3β)/nuclear factor erythroid 2-related factor 2 (NRF2) to attenuate brain I/R injury in transcerebral I/R-injured rats and transoxygenic glucose deprivation/reperfusion (OGD/R)-injured SY5Y cells.
Material And Methods: Remimazolam was added at the beginning of cell and rat reperfusion, and the PI3K/AKT inhibitor LY294002 was added to inhibit the AKT/GSK-3β/NRF2 pathway 24 h before cellular OGD/R treatment and 30 min before rat brain I/R treatment.

Aims: We aim to explore the predictive value of admission blood glucose to serum albumin ratio (AAR) for futile recanalization after successful interventional recanalization of acute cerebral infarction.
Methods: We retrospectively collected the data of patients suffered from acute cerebral infarction due to anterior circulation large vessel occlusion and received successful interventional recanalization from January 2019 to November 2023. Statistical analysis of clinical data was conducted using SPSS 26.

Background: Ischemic stroke is a major public health concern, contributing significantly to global morbidity and mortality. Recent studies have suggested that alterations in liver enzymes may be linked to the risk of developing a stroke. However, the relationship between liver enzymes and ischemic stroke remains unclear.
