The goal of this observational study is to examine the relationship between digestive symptom scores, serum pepsinogen indices, and histopathological OLGA and OLGIM systematic staging of the gastric mucosa in patients with chronic atrophic gastritis(CAG), aiming to determine the degree of correlation between clinical manifestations, non-invasive laboratory tests, and the gold standard of diagnostic histopathology.To evaluate the comprehensive therapy, readiness and acceptance of acupuncture, utilization rates of various acupuncture therapies, self-assessed efficacy of acupuncture, and endoscopic histopathological alterations in patients with CAG.According to the aforementioned study, it is anticipated to enhance the optimization of acupuncture clinical research protocols for chronic atrophic gastritis, improve treatment efficacy, and offer more effective and rational therapy alternatives for patients.The main question it aims to answer is:
To determine if the outcomes of combined serologic testing of symptoms in patients with CAG can serve as a method for monitoring disease development and if long-term follow-up can be supported？
A group of participants with recorded GI symptom scores and blood pepsinogen levels will respond to online survey questions regarding the severity of their chronic atrophic gastritis progression over the course of 1 year.

The conduct of a pilot trial is of great significance as a means of assessing the feasibility and harmonization of the research and is a very necessary precursor to the better conduct of formal trials. The primary aim of this pilot study is to assess the feasibility of a PC-TEAS in improving the quality of life of cancer patients with pain, with the aspiration of providing process evidence base and an assessment of the intervention for conducting a formal trial. the secondary outcome is to assess the clinical efficacy of the PC-TEAS.
