In order to study the protective effects on motor and cognitive function by inhibiting IL-1β as delayed as 24h after global ischemia, we designed behavioral testing protocol and histology detection after 10 min transient global ischemia followed by IL-1β or its antibody intracerebroventricular injection. We found benefit of IL-1β antibody treatment 24h after ischemia in cognitive function recovery. But no obvious amelioration in motor function was found. Further we detected cell morphology and survival by histology staining and proved IL-1β antibody could reduce ischemia induced cell morphological changes and cell loss in hippocampus, which related with cognitive function. Present results indicate intervening IL-1β pathway could be helpful in cognitive function recovery even as late as 24h after ischemia happens.

Altitude training has been widely adopted. This study aimed to establish a mice model to determine the time point for achieving the best endurance at the lowland. C57BL/6 and BALB/c male mice were used to establish a mice model of hypoxic training with normoxic training mice, hypoxic mice, and normoxic mice as controls.

Anhedonia, characterized by diminished motivation and pleasure sensitivity, is increasingly recognized as prevalent among patients with chronic pain. Deep Endometriosis (DE), the most severe endophenotype of the disease, is commonly presented with chronic pelvic pain. This cross-sectional study reports, for the first time, the prevalence of anhedonia in a sample comprised by 212 premenopausal women with suspected DE referred to a tertiary hospital.

Background: Thyroid disorders have significant clinical sequelae, including impaired growth in children, metabolic abnormalities, and impaired cognitive function. However, available studies on burden of thyroid diseases in people with human immunodeficiency virus (HIV), particularly its prevalence and its interaction with HIV related factors (like CD4 count), are controversial. This review aimed to provide a comprehensive summary and analysis on the extent of thyroid dysfunctions in this population.

Background: Mild cognitive impairment (MCI) is a high-risk factor for dementia and dysphagia; therefore, early intervention is vital. The effectiveness of intermittent theta burst stimulation (iTBS) targeting the right dorsal lateral prefrontal cortex (rDLPFC) remains unclear.
Methods: Thirty-six participants with MCI were randomly allocated to receive real (n = 18) or sham (n = 18) iTBS.
