White matter hyperintensities had a correlation with the cerebral perfusion level, but no correlation with the severity of large vessel stenosis in the anterior circulation.

Objective: The contribution of large vessel stenosis to the development of white matter hyperintensities (WMHs) has not been fully elucidated. This study aims to explore the correlation between ipsilateral white matter hyperintensities (WMHs) and the severity of large vessel stenosis in the anterior circulation and cerebral perfusion level, as well as analyze the factors influencing WMHs.

Methods: A cross-sectional study of 150 patients with unilateral anterior circulation large vessel stenosis of ≥50% was conducted.

Clinical epidemiological characteristics of nitrous oxide abusers: A single-center experience in a hospital in China.

Purpose: This study investigated the clinical epidemiological characteristics of nitrous oxide (N O) abusers in a hospital in China, which have not been systematically reported.

Methods: The characteristics of patients abusing N O who were examined and treated at the Affiliated Hospital of Xuzhou Medical University from January 2017 to December 2020 were analyzed.

Results: A total of 61 patients (average age: 21.
