Background: To analyze the difference of serum gastrin-17 (G17) level in healthy people with different sex, age, and body mass index (BMI), to explore the correlation between G17 and pepsinogen, and to study the influences of Helicobacter pylori (H. pylori) infection and various inflammatory factors on G17 secretion level.
Methods: A total of 531 subjects who received physical examination in our center from April 2019 to December 2019 were enrolled in the study. All subjects were tested for G17, pepsinogen I (PGI), pepsinogen II (PGII), PGI/PGII ratio (PGR), H. pylori, serum amyloid A (SAA), C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). The difference of G17 secretion in different subjects and its correlation with PG were analyzed to investigate H. pylori infection and expound the effects of inflammatory indicators on G17.
Results: There was no significant difference in G17 secretion level in people with different sex, age and BMI (p > .05). G17 positively correlated with PGI and PGII, but negatively correlated with PGR. The G17 level of H. pylori-positive subjects was 10.16 ± 12.84, and prominently higher than that of H. pylori-negative subjects (3.27 ± 6.65). SAA and H. pylori infection were the greater risk factors for G17 abnormality among various indicators. CRP and ESR had no effect on G17 abnormality.
Conclusions: G17 secretion is closely related to PG and H. pylori. Combined screening contributes to early screening of gastrointestinal diseases in normal people or groups at high risk for gastric cancer, but the influence of inflammatory indicators on G17 should be excluded to improve the reliability of the results.

Aims: This study aims to assess the serum levels of pepsinogen (PG)I, PG II, and gastrin (G17) in patients with gastric intestinal metaplasia (GIM) and evaluate their correlation with demographic characteristics.
Methods: A total of 247 normal controls (NC) and 240 patients diagnosed with GIM were enrolled in this study. All participants underwent a gastroscopy procedure followed by pathological examination for diagnosis confirmation.

Objective: This study aimed to investigate the diagnostic potential of serum CXC chemokine ligand 5 (CXCL5) in patients with chronic atrophic gastritis (CAG) and to establish a prediction model for better diagnosis of CAG.
Methods: A retrospective analysis was conducted, encompassing 570 cases of CAG patients admitted to the Department of Gastroenterology of the Second Affiliated Hospital of Anhui University of Traditional Chinese Medicine, who underwent gastroscopy and received pathologically confirmed diagnoses between June 2018 and June 2023. Additionally, 570 cases without CAG who underwent health checkups were included and classified into the control group.

Objective: Gastric adenocarcinoma (GAC) is the 17th most common cancer in the UK with a 5-year survival rate of 22%. GastroPanel (Biohit Oyj; Helsinki, Finland) is an ELISA kit that measures pepsinogen I (PGI); pepsinogen II (PGII); gastrin-17 (G-17); and Helicobacter pylori IgG antibodies (Hp IgG). PGI and the PGI/PGII ratio correlate inversely with the severity of chronic atrophic gastritis (AG).

Background: Chronic atrophic gastritis (CAG) is a chronic disease of the gastric mucosa characterized by a reduction or an absolute disappearance of the original gastric glands, possibly replaced by pseudopyloric fibrosis, intestinal metaplasia, or fibrosis. CAG develops progressively into intestinal epithelial metaplasia, dysplasia, and ultimately, gastric cancer. Epidemiological statistics have revealed a positive correlation between the incidence of CAG and age.
