Article Abstract
Background: Gastric Helicobacter pylori (H. pylori) is linked with chronic gastritis, peptic ulcer disease, and gastric malignancy. This study aims to investigate the association of gastric H. pylori with colorectal adenomatous polyps (CAP) in the Chinese population.
Methods: One thousand three hundred seventy five workers of China Petroleum and Chemical Corporation Sinopec Zhenhai Refining & Chemical Branch were recruited. Carbon-13 urea breathes test, and colorectal biopsies were utilized to detect H. pylori and CAP. The correlation between the number and distribution of CAP with H. pylori infection (HPI) was determined. Logistic regression models were applied to calculate the effect of H. pylori on the risk of CAP and pathway studio was used to attribute the cellular processes linking HPI and adenomatous polyps.
Results: One hundred Eighty participants were diagnosed as CAP, and 1195 participants were classified as healthy control. The prevalence of HPI in the CAP group was significantly higher than that in the healthy control group (57.8% verse 40.1%) (p<0.001). It was the number not the distribution of CAP corrected with H. pylori status. An increased risk of CAP was found to be associated with H. pylori (OR = 3.237; 95.0% CI 2.184-4.798, p = 0.00) even after multiple parameters adjustment. Pathway studio analysis demonstrated that HPI connected with CAP at multi-level.
Conclusions: HPI is associated with an increased risk of CAP in the Chinese population.

Helicobacter pylori was first characterized as an obligate bacterial pathogen in 1983. Since then, substantial advances have been made in understanding the pathophysiology of H. pylori infection, optimizing diagnostic and therapeutic strategies, and expanding testing and treatment-including in the prevention of gastric malignancies.

Purpose Of Review: Acid suppression is the mainstay of management of common foregut disorders, including gastroesophageal reflux disease (GERD), peptic ulcer disease and Helicobacter pylori infection. Drawbacks of standard management with proton pump inhibitors (PPIs) include acid lability requiring enteric coating, slow onset of effect, lack of suppression of nocturnal acid breakthrough, and need for administration before meals.
Recent Findings: Potassium-competitive acid blockers (PCABs) are a novel class of acid suppressants that are effective in the management of symptomatic and erosive GERD, peptic ulcer disease and H.

Allergic asthma is an inflammatory airway disease influenced by genetic and environmental factors and orchestrated by imbalance between T helper 1 cell (Th1) and two immune responses. Inflammation contributes to pathological changes and remodeling in tissues such as the vascular, lung, heart, and beds. The purpose for this study was to evaluate the effects of allergic asthma on heart pathology and remodeling.

Objective: The key molecular events signifying the -induced gastric carcinogenesis process are largely unknown.
Methods: Bulk tissue-proteomics profiling were leveraged across multi-stage gastric lesions from Linqu ( = 166) and Beijing sets ( = 99) and single-cell transcriptomic profiling ( = 18) to decipher key molecular signatures of -related gastric lesion progression and gastric cancer (GC) development. The association of key proteins association with gastric lesion progression and GC development were prospectively studied building on follow-up of the Linqu set and UK Biobank ( = 48,529).

Nitazoxanide (NTZ), an FDA-approved drug, served as the framework for synthesizing 22 new broad-spectrum antimicrobial agents from 4-aminosalicylic acid via protection-deprotection, Staudinger reduction, Clauson-Kaas pyrrole synthesis, and nucleophilic substitution. These compounds were evaluated for antibacterial, antimycobacterial, and antitrypanosomal activities. Several compounds, particularly 10, 11, 13, and 22, surpassed the antibacterial activity of NTZ and its active metabolite tizoxanide (TIZ) against all tested pathogens, with MICs ranging from 1.
