Summary: Background: Contact-based intervention has been documented and proved effective on reducing stigma of mental illness in high-income countries, but it is still unclear about the effectiveness of the contact-based intervention among family caregivers of persons with schizophrenia (FCPWS) in low- and middle-income countries including rural China. Methods: We conducted a cluster randomized controlled trial in FCPWS in eight rural townships in Xinjin district of Chengdu city in Southwest China. The FCPWS in these townships were randomly allocated to the Enhancing Contact Model (ECM), Psychoeducational Family Intervention (PFI), or Treatment as Usual (TAU) group. FCPWS in three groups were provided specific interventions and follow-ups. By using a mixed-effect model, our goal was to examine the differences in affiliate self-stigma scale (ASSS) scores among three groups with the data collected at baseline (T0), post-intervention (T1), 3-month (T2), and 9-month (T3) follow-up timepoints, respectively. This trial is registered with ChiCTR, number ChiCTR2000039133. Findings: In April 2019, 253 FCPWS from 8 townships were randomly assigned to receive either ECM (cluster=3, n=90), PFI (cluster=2, n=81), or TAU (cluster=3, n=82). Compared with participants in the TAU group, participants in the ECM group had statistically significantly lower ASSS scores at 9-month follow-up (estimated parameter [EP]= -5.51, 95% CI -10.27 to -0.74, p=0.02). There were no statistically significantly different ASSS scores at 9-month follow up between ECM and PFI groups. Compared with participants in the PFI group, younger (

Alzheimer's disease (AD) is the most common form of dementia among the elderly with women exhibiting a higher risk than men for the disease. Due to these gender differences, there is great interest in the role that estrogens play in cognitive impairment and the onset of the classic amyloid and tau lesions in AD. Human and rodent studies indicate a strong association between low brain aromatase, sex hormone levels, and beta amyloid deposition. Therefore, the effects of depleting both circulating and brain estrogen levels, through gonadectomy and/or treatment with the aromatase inhibitor, anastrozole, upon hippocampal AD-like pathology in male and female 3xTgAD mice were evaluated. Liquid chromatography–mass spectrometry revealed anastrozole serum levels of 10.19 ng/mL and for the first time brain levels were detected at 4.7 pg/mL. Densitometric analysis of the hippocampus revealed that anastrozole significantly increased Aβ- but not APP/Aβ-immunoreactivity in intact 3xTgAD females compared to controls (p
