Relationship between Changes in Peripheral Blood TLR4 MyD88 NF-κB and PG Levels and Hp Infection Lesion Progression and Inflammatory Response in Patients with Atrophic Gastritis
Abstract:Objective: To investigate the changes in the expression of serum Toll-like receptor 4 (TLR4), myeloid differentiation factor-88 (MyD88), nuclear factor κB (NF-κB), and pepsinogen (PG Ⅰ, PG Ⅱ) in patients with atrophic gastritis, and their clinical significance. Methods: A total of 98 patients with atrophic gastritis confirmed by gastroscopy taking pathological tissue examination during the period from December 2020 to March 2023 in the First Hospital of Yulin City were selected as Group A, 100 patients with non-atrophic gastritis confirmed by examination during the same period were selected as Group B, and 100 volunteers for health physical examination were selected as Group C. The serum of the study subjects of the three groups were examined and compared with those of the three groups in terms of the expression changes of serum TLR4, MyD88, NF- κB, PGⅠ, PGⅡ, interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α) levels of the three study groups, and stratified according to whether the patients were co-infected with Hp infection or not, and endoscopic grading criteria of atrophic gastritis for comparing the differences of the above indexes. Results: The TLR4, MyD88, NF-κB, PGII, IL-6, IL-1β, and TNF-α of patients in Group A were significantly higher than those in Groups B and C, and the PGⅠ assay was significantly lower than those in Groups B and C, with a statistically significant difference (P<0.05); the TLR4, MyD88, NF- κB, PGII, IL-6, IL-1β, and TNF-α were significantly higher than those in group B, and the values of PGⅠ assay were significantly lower than those in group C, and the difference was statistically significant (P<0.05); in the Hp-positive group, the values of TLR4, MyD88, PGII, IL-6, IL-1β, and TNF-α were significantly higher than those in the Hp-negative group, and the values of PGⅠ assay were significantly lower than those in the Hp-negative group, and the difference was statistically significant (P<0.05); TLR4, MyD88, NF-κB , PGⅡ, IL-6, IL-1β, and TNF-α of patients with grade III lesions were significantly higher than those of patients with grades II and I, and the values of PGⅠ assay were significantly lower than those of patients with grades II and I, and the difference was statistically significant (P<0.05); TLR4 of patients with grade II TLR4, MyD88, NF-κB , PGII, IL-6, IL-1β, TNF-α were significantly higher in patients with grade II lesions than in patients with grade I. The PGⅠ assay was significantly lower than that in patients with grade I, and the difference was statistically significant (P<0.05); TLR4, MyD88, NF-κB with IL-6, IL-1β, and TNF-α were all significantly positively correlated (P<0.05), and there was no significant correlation between PGII and PGⅠ and IL-6, IL-1β, and TNF-α (P>0.05). Conclusion: The TLR4/MyD88/NF-κB pathway is related to the degree of lesions and the occurrence of Hp infection in patients with atrophic gastritis, and regulates the severity of inflammatory response in patients to a certain extent.
