Depressive symptoms are highly prevalent in patients with chronic atrophic gastritis (CAG) but are frequently under-detected due to stigma and reliance on subjective questionnaires. This multicenter, cross-sectional observational study aims to validate a novel clinical triage workflow. It repurposes routine vascular assessments (specifically dorsalis pedis artery ultrasound and arterial stiffness metrics) as objective "biological entry points" to facilitate mental health referrals. The study will enroll approximately 450-520 adults with histologically confirmed CAG across four clinical centers in China. The primary objective is to determine the diagnostic accuracy of these vascular biomarkers for identifying patients with moderate-to-severe depressive symptoms (PHQ-9 score >= 10). Secondary objectives include evaluating the implementation feasibility (e.g., referral uptake, screening completion rate) of this integrated care model in routine gastroenterology practice.

The goal of this clinical trial is to learn if a traditional Chinese medicine formula called "Huangjing Yangji Formula," combined with elastic band resistance training, works better than exercise alone to improve physical function and muscle strength in older adults with sarcopenia (age-related muscle loss). The main questions it aims to answer are:
Does the combined treatment improve participants' overall physical performance scores more than exercise with a placebo?
Does it lead to better outcomes in walking speed, balance, muscle strength, body composition, nutrition, mood, sleep, and overall quality of life?
Researchers will compare two groups. One group will take the real Huangjing Yangji Formula granules and do the standardized elastic band resistance training. The other group will take placebo granules (a look-alike mixture with no active medicine) and do the same training.
Participants will:
Take the assigned granules twice daily for 3 months.
Complete a standardized elastic band exercise program 3 times per week for 3 months (with both group and home sessions).
Attend three assessment visits (at the start, after 3 months, and 1 month after treatment) for tests and questionnaires.
Provide blood samples at the start and after 3 months for routine safety tests and special muscle health markers.

The study aims to construct an early warning model for Osteoporotic Vertebral Compression Fracture (OVCF) by integrating TCM syndrome patterns with modern risk factors. This is a multi-center cohort study on OVCF integrated with disease and syndrome differentiation in Traditional Chinese Medicine (TCM).
