Eradication of can significantly reduce the risk of recurrent peptic ulcer and its complications (14). were recognized in the protein expression levels of occludin, NOS, EGF and EGFR between the high and low bleeding risk organizations. In the intense cold weather, the manifestation of HSP70 and the mucus thickness of the gastric antrum in the high bleeding risk group were significantly DBU lower than those in the low bleeding risk group. The protein expression levels of occludin, HSP70, NOS and EGFR in the intense chilly weather were significantly lower than those in the intense sizzling weather, whereas the gastric acid secretion was significantly higher in the intense cold weather than that in the intense sizzling climate. In conclusion, low manifestation of HSP70 in the gastric mucosa and reduced gastric mucus thickness may play key tasks in the mechanism of PUB in intense chilly climates. The significant decrease in barrier factors and increase in damage in intense cold climates may be associated with the seasonal pattern of peptic ulcers. (H. pylori) illness and nonsteroidal anti-inflammatory medicines (NSAIDs). Certain studies have indicated the incidence of peptic ulcers in chilly climates is significantly higher than that in sizzling climates (2,3). A earlier study has additionally found that the incidence of PUB is definitely inversely proportional to the temp and correlated with the degree of temp variation (3). Chilly weather and quick weather switch may induce PUB (2,3), but little is known concerning its specific pathogenesis. Gastric mucosal damage and barrier factors were therefore examined in intense climates to clarify the pathogenesis of PUB under intense climate conditions. Individuals and Methods Individuals The study was conducted with the approval of the Ethics Committee of the First Affiliated Hospital of Nanchang University or college (Nanchang, DBU China). A total of 176 individuals with active peptic ulcer with or without bleeding who have been undergoing endoscopic examinations in the First Affiliated Hospital of Nanchang University or college during periods of intense sizzling or cold weather were included in the study. The intense sizzling weather period was between July and September 2009, when the average temp was 30C, and the intense chilly weather period was between December 2009 and February 2010, when the average temp was 10C. The patient demographics are summarized in Table I. Individuals were eligible for inclusion in the present study if they met the following criteria: i) Age 18 years; ii) resident of Jiangxi province; and iii) showing with active peptic ulcer. The active peptic ulcer had to be in conformity with one of the following conditions: Continuity of 5 mm, multiple ulcers or actively bleeding ulcer. The exclusion criteria were as follows: i) Severe organ diseases of important organs, including the heart, lung, liver, kidney and brain; ii) pregnant or lactating DBU females; iii) patients with mental health problems and patients who are unable to provide a medical history; and iv) patients who have received treatment with Rabbit Polyclonal to Transglutaminase 2 proton pump inhibitors (PPIs) or other gastroprotective agents within the last two weeks. The subjects were divided into high and low bleeding risk groups according to their histories of PUB or observations of hemorrhages upon endoscopic examination. Table I Patient demographics according to bleeding risk group and extreme climate conditions. contamination was detected using altered Giemsa staining. The paraffin-embedded sections were conventionally deparaffinized in xylene twice for 10 min, rehydrated.
