Clinical trials

The goal of this clinical trial is to learn if silkworm pupa powder works to improve the nutritional status of Alzheimer's disease patients. The main questions it aims to answer are: * Does silkworm pupa powder evaluate the effectiveness of silkworm pupae in improving sarcopenia, frailty and quality of life in AD patients? * Does silkworm pupa powder improve cognitive function in AD patients? Researchers will compare silkworm pupa powder to a placebo (a look-alike substance that contains no drug) to see if silkworm pupa powder works to improve the nutritional status of Alzheimer's disease patients. Participants will: * Take drug silkworm pupa powder or a placebo every day for 3 months. * Visit the clinic once every 4 weeks for checkups and tests. * Keep a diary of their daily consumption.

This study was designed as a single-center retrospective analysis aimed at investigating whether COVID-19 infection increases the risk or burden of radiation-induced pneumonitis in breast cancer patients.

The BRAIN-CSVD study is a single-center prospective cohort study focusing on cerebral small vessel disease (CSVD).Patients enrolled in this research will undergo assessments for vascular risk factors, cognitive and other neurological functions, neuroimaging, and biomarkers. The study aims to explore imaging and biomarker predictors of CSVD progression, and the pathophysiological mechanisms of CSVD.
