RESUMO
Objective:To preliminarily understand the living habits, medication taking and treatment status including the therapeutic regimen, compliance and short-term efficacy of patients with chronic atrophic gastritis and erosion in Beijing area.Methods:From April to September in 2019 at Peking Union Medical College Hospital, Peking University Third Hospital and Peking University Shougang Hospital, the outpatients with chronic atrophic gastritis and erosion diagnosed with endoscopy within two weeks before visiting were prospectively included in this non-interventional observation study. Chi square test was used for statistical analysis.Results:A total of 277 patients with chronic atrophic gastritis and erosion had complete follow-up data, of which male patients accounted for 49.8% (138/277). The common initial symptoms of patients with chronic atrophic gastritis and erosion included acid reflux, abdominal distension, epigastric pain and postprandial distension, which accounted for 60.3% (167/277), 59.6% (165/277) , 58.8% (163/277) and 52.3% (145/277), respectively. For treatment, 36.8% (102/277) of the patients only received lifestyle instruction without medication. Among the patients with medication treatment, the short-term efficacy of gastric mucosal protectants+ proton pump inhibitor+ gastro-kinetic agent for abnominal distension, postprandial distention, acid reflux and nausea was highest as compared with other therapeutic regimen, and the differences were statistically significant ( χ2=25.18, 19.49, 13.75, 8.84, all P<0.05). Conclusions:Chronic gastritis with erosion may be caused by a combination of multiple factors, and the symptoms of which lack specific. If necessary, gastroscopy may help the diagnosis. Individualized treatment strategies based on the symptoms of patients is needed for treatment.
RESUMO
Background: Long-term use of aspirin can cause varying degrees of gastric mucosal injuries. Hydrotalcite may play a protective role on gastric mucosal injuries through multiple mechanisms. Aims: To investigate the protective effect of hydrotalcite on aspirin-induced gastric mucosal injury and its possible mechanism in an in vitro study. Methods: Human gastric mucosal epithelial cell line GES-1 was selected and divided into three groups: normal control group, injury group and protection group. GES-1 cells in the latter two groups were co-cultured with aspirin (9 mmol/L), and cells in the protection group was further treated with hydrotalcite (0.6 mg/mL) after aspirin administration. After culturing for 12 hours, morphology of GES-1 cells was observed by inverted microscope and transmission electron microscope. Cell proliferation and apoptosis were assessed by MTT assay and flow cytometry, respectively. Proteomics was used to identify the differentially expressed proteins between injury group and protection group. Results: Compared with the injury group, GES-1 cells in the protection group remained in a relatively intact structure with higher survival rate and lower apoptosis rate (P<0.05). Proteomics revealed that the expressions of T-complex protein 1 subunit beta (TCP-1β) and thioredoxin-dependent peroxide reductase 3 (PRX3), which were related with protein folding and assembly, cytoskeleton function, and antioxidative stress, were up-regulated in GES-1 cells in the protection group. Conclusions: Hydrotalcite can reduce the aspirin-induced gastric mucosal injury via promoting cell proliferation and inhibiting apoptosis. Improvement of the structure and function of intracellular proteins and antioxidative stress might be implicated in its cytoprotective effect.
