Proteomics Study of Mild Cognitive Impairment and Alzheimer's Disease

This study intends to adopt standardized and rigorous cross-sectional research, collect biological specimens (including blood, feces, urine, saliva and tongue coating) from eligible subjects, and use liquid chromatography/mass spectrometry (LC-MS/MS) technology to explore early warning indicators of protein in patients with mild cognitive impairment and Alzheimer's disease

The problem of population aging is getting worse, the prevalence of senile dementia is increasing, and Alzheimer's disease (AD) is the most common type of dementia. There is no effective treatment for AD. Most interventions can only alleviate the condition and delay the development. Therefore, early diagnosis and prevention of AD are extremely important. However, the current diagnostic measures are not suitable for clinical promotion due to their traumatic nature, so there is an urgent need for a more suitable clinical early identification and diagnosis method. Proteomics research technology is the leading research technology in China. It can be applied to research on disease markers, pathogenesis, and drug target discovery. Therefore, this study intends to adopt standardized and rigorous cross-sectional research, collect biological specimens (including blood, feces, urine, saliva and tongue coating) from eligible subjects, and use liquid chromatography/mass spectrometry (LC-MS/MS) technology to explore early warning indicators of protein in patients with mild cognitive impairment and Alzheimer's disease
