Study on the gastic leptin and helicobacter pylori associated gastritis / 中华检验医学杂志

ABSTRACT

Objective To explore the pathophysiological role of gastric leptin in helicobacter associated gastritis.Methods Patients undergoing gastroscopy were involved in the study.Helicobacter pylori infection was diagnosed by use of Hp-ureA-PCR,~(14)C urea breath test and rapid urease-nessler′s test. The level of leptin in local gastric mucosa and plasma were detected by ELISA. The level of IL-1? and IL-1ra in local gastric mucosa were detected by RIA.Results Total of 31 H pylori positive and 30 H pylori negative patients with chronic gastritis were founded. The level of Leptin and IL-1ra in the gastric mucosa in H pylori positive patients were significantly increased as compared with that in H pylori negative group (P 0.05).Gastric leptin closely related to IL-1? in H pylori positive group(r= -0.78,P
