Autophagy is a lysosome-mediated degradation process for non-essential or damaged cellular constituents, playing an important homeostatic role in cell survival, differentiation and development to maintain homeostasis. Autophagy is involved in tumors as well as neurodegenerative, cardiovascular and cerebrovascular diseases. Recently, active compounds from traditional Chinese medicine (TCM) have been found to modulate the levels of autophagy in tumor cells, nerve cells, myocardial cells and endothelial cells. Ischemic stroke is a major cause of neurological disability and places a heavy burden on family and society. Regaining function can significantly reduce dependence and improve the quality of life of stroke survivors. In healthy cells, autophagy plays a key role in adapting to nutritional deprivation and eliminating aggregated proteins, however inappropriate activation of autophagy may lead to cell death in cerebral ischemia. This paper reviews the process and the molecular basis of autophagy, as well as its roles in cerebral ischemia and the roles of TCM in modulating its activity.

Background: Tyrosine kinase inhibitors (TKIs) improve prognosis in chronic myeloid leukemia (CML). Nilotinib and ponatinib, second- and third-generation TKIs, respectively, have been reported to cause adverse vascular occlusive events such as myocardial infarction and peripheral arterial disease. However, little is known about the risk of cerebral infarction associated with severe cerebrovascular stenosis, which is a late complication of TKIs.

Aneurysmal Subarachnoid Hemorrhage (aSAH), resulting from ruptured aneurysms, is a major contributor to stroke-related mortality and morbidity. Despite advances in healthcare, aSAH remains severe and often leads to complications such as cerebral vasospasm (CV), cerebral infarction, and delayed ischemic neurological deficits (DIND). Clazosentan, an endothelin receptor antagonist, has demonstrated potential in alleviating vasospasm and its associated outcomes, although evidence of its efficacy remains unclear.

Background: Hemorrhage is a major complication of brain arteriovenous malformations (AVMs) embolization, which can be related to persistent arteriovenous shunts that were not completely occluded during the embolization. In transvenous embolization (TVE) this risk is deemed higher for AVMs larger than 3 cm featuring multiple veins of drainage. Herein, we will discuss a few selected cases where brain AVMs with more than one draining vein were deemed safe for curative embolization with advanced endovascular techniques after a careful anatomical study through the four dimensional-digital subtraction angiography (4D-DSA) imaging.

Introduction: This study aimed to investigate the associations among seizures, clinical characteristics, and brain injury on Magnetic Resonance Imaging (MRI) in infants with Hypoxic Ischemic Encephalopathy (HIE), and to determine whether these findings can predict unfavorable neurodevelopmental outcomes.
Method: Clinical and electrographic seizures were assessed by amplitude-integrated electroencephalogram, and the extent of brain injury was evaluated by using MRI. At 12‒24 months of age, developmental impairment or death was assessed.

Objective: Hirudin has shown potential in promoting angiogenesis and providing neuroprotection in ischemic stroke; however, its therapeutic role in promoting cerebrovascular angiogenesis remains unclear. In this study, we aimed to investigate whether hirudin exerts neuroprotective effects by promoting angiogenesis through the regulation of the Wnt/β-catenin signaling pathway.
Methods: An in vitro model of glucose and oxygen deprivation/reperfusion (OGD/R) was established using rat brain microvascular endothelial cells (BMECs).
