Background: Little is known about the dynamic process of the outer-wall boundary during intensive lipid-lowering therapy in patients with intracranial atherosclerotic stenosis and its clinical implications.

Methods: We analyzed patients with first-ever acute ischemic stroke attributed to intracranial atherosclerotic stenosis who received intensive lipid-lowering therapy with high-dose statins and PCSK9i (proprotein convertase subtilisin/kexin type 9 inhibitor). Data were obtained from a multicenter cohort study at 15 hospitals across China and our institutional database in Beijing, China.

Background: We aimed to investigate the effects of evolocumab, a proprotein convertase subtilisin/kexin type-9 inhibitor for intensive lipid-lowering, on intracranial atherosclerotic stenosis.

Methods: From a prospectively established high-resolution magnetic resonance imaging database, consecutive patients with intracranial atherosclerotic stenosis (≥50%) with 2 detections of high-resolution magnetic resonance imaging over 6 months were included in this retrospective analysis. Eligible patients were grouped by treatment: evolocumab add-on (evolocumab) versus no evolocumab (evolocumab).

Intracranial atherosclerosis (ICAS), a common cause of ischemic stroke, remains a therapeutic challenge due to complex intracranial anatomy and intervention risks. Although ICAS develops intracranially, cerebral artery innervation originates in the peripheral nervous system. The scarcity of human intracranial specimens has hindered investigations into the potential role of Schwann cells (SCs) in neurovascular homeostasis.

Background: The prevalence of heart failure (HF) continues to rise with a growing impact on younger populations, while epidemiological comprehensive data on HF in adolescents and young adults remain scarce.

Objectives: This study aimed to report population shifts and HF burden among individuals aged 15-49 years from 1990 to 2021, with projections through 2035.

Methods: Data were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 for individuals aged 15-49 years.

Background: Deep tiny flow voids (DTFVs) have recently been identified as a novel form of collateral circulation linked to chronic steno-occlusive atherosclerotic middle cerebral artery (MCA) lesions, detectable via high-resolution magnetic resonance imaging (HR-MRI). To date, no study has focused on the presence and clinical significance of DTFVs in acute MCA atherosclerotic occlusion.

Materials And Methods: This retrospective study included patients with acute MCA atherosclerotic occlusion from two multicenter HR-MRI cohorts.

Introduction: There has been an increasing demand for imaging methods that provide a comprehensive evaluation of intracranial clot and collateral circulation, which are helpful for clinical decision-making and predicting functional outcomes. We aimed to quantitatively evaluate acute intracranial clot burden and collaterals on high-resolution magnetic resonance imaging (HR-MRI).

Methods: We analyzed acute ischemic stroke patients with internal carotid artery or middle cerebral artery occlusion in a prospective multicenter study.

Background: High-resolution magnetic resonance vessel wall imaging (HRMR-VWI) is a promising technique for identifying intracranial vulnerable plaques beyond lumen narrowing. However, the association between HRMR-VWI characteristics and recurrent stroke remains uncertain.

Aims: This study aimed to investigate the association between HRMR-VWI characteristics and recurrent ipsilateral stroke in patients with symptomatic intracranial atherosclerotic steno-occlusive disease (ICAS).

Background: China is one of the countries with the highest burden of stroke. Implementing multidimensional management guidelines will help clinicians practise evidence-based care, improve patient outcomes and alleviate societal burdens. This update of the 2019 edition will provide the latest comprehensive recommendations for the diagnosis and treatment of ischaemic cerebrovascular diseases.

Background: Intracranial atherosclerotic stenosis (ICAS) is one of the leading causes of stroke worldwide. Current diagnostic evaluations and treatments remain insufficient to assess the vulnerability of intracranial plaques and reduce the recurrence of stroke in symptomatic ICAS. On the other hand, asymptomatic ICAS is associated with an increased risk of cognitive impairment.

Background: The prevalence of stroke in young adults is increasing. We investigated the monogenic basis of young adult cryptogenic stroke patients.

Methods: This multicenter study enrolled cryptogenic stroke patients under 55 years old, and individuals with nonstroke diseases were included as controls.

This study aimed to identify independent risk factors for first occurrence of stroke in Chinese individuals based on prospective cohort studies. Forty prospective cohort studies assessing 1,984,552 individuals were selected for the final meta-analysis. The identified risk factors for stroke in the Chinese population included old age (RR = 1.

In vivo studies on association between wall shear stress (WSS) and intracranial plaque are deficient. Based on the three-dimensional T1-weighted high-resolution magnetic resonance imaging (3DT1 HR-MRI) data of patients with low-grade stenotic (<50%) atherosclerotic middle cerebral artery (MCA) and subjects with normal MCA, we built a three-dimensional reconstructed WSS model by computational fluid dynamics (CFD) technique. Three-dimensional registration of the CFD model to the HR-MRI was performed with projections based on the resolution and thickness of the images.

Aim: To investigate whether Dihydromyricetin (DHM) inhibits cell proliferation and promotes apoptosis by downregulating Notch1 expression.

Methods: The correlation between Notch1 and Hes1 (a Notch1 target molecule) expression in hepatoma samples was confirmed by qRT-PCR. In addition, MTT assays, flow cytometry and TUNEL analysis showed that DHM possessed strong anti-tumor properties, evidenced not only by reduced cell proliferation but also by enhanced apoptosis in QGY7701 and HepG2 hepatocellular carcinoma (HCC) cells.

F10 is a novel hydatidiform mole (HM)-associated gene that was initially identified during a study into the pathogenesis of HMs. However, the role of the F10 gene requires further investigation. Our, previous studies have indicated that F10 may be involved in the malignant transformation of HMs and the development of certain types of adenocarcinoma, and that the overexpression of F10 may lead to excessive proliferation and decreased apoptosis of A549 cells.
