Background:
Aging is a primary risk factor for chronic diseases, yet safe and effective interventions remain limited. Traditional Chinese Medicine (TCM) highlights the role of acupuncture in health preservation, with ST36 (Zusanli) being a key acupoint for longevity. Preclinical studies suggest ST36 acupuncture modulates inflammation and oxidative stress, but robust clinical evidence is lacking. This trial aims to evaluate the efficacy of ST36 acupuncture in delaying aging and preventing age-related diseases through biomarkers and clinical outcomes.
Methods:
A single-center, randomized, single-blinded, controlled trial will enroll 120 healthy participants aged 45-70 years. Participants will be allocated to manual acupuncture, sham acupuncture, or blank control groups. The intervention involves 36 sessions over 12 weeks. Primary outcomes include aging biomarkers (DNA methylation, plasma cytokines) and 3D facial/thermal imaging for biological age estimation. Secondary outcomes assess quality of life (SF-36) and sleep quality (PSQI). Adverse events will be systematically documented.
Discussion:
This study will provide evidence on the anti-aging effects of ST36 acupuncture and its potential integration into preventive healthcare. Results may inform strategies to address global aging challenges and promote healthy longevity.

The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
