ABSTRACT
Objective To survey the infection status and related factors of Helicobacter pylori(H.pylori) among adult population receiving physical examination in Yunnan plateau area so as to provide a basis for control and treatment of H.pylori infection at the present stage.Methods The epidemiological survey method was applied to collect the intact data on adult health physical examination from Jan.2013 to Feb.2015,including the results of survey by adopting the unified national questionnaire and 13 C-urea breathe test for detecting H.pylori.The guestionniare contents had the basic conditions,socid economy stalus,personal and family health status cinecluding whether sufferring from digestive diseases or symptoms,dietary habit,etc.Results A tatae of 1 680 eligi ble subjects were included in this study.The total infection rate of H.pylori was 33.5％,which of male and female were 33.2％ and 34.5 ％ respectively,the difference was not statistically significant (P＞0.05).The peak of H.pylori infection rate was in the age group 40-49 years(36.7 ％),but the difference among different age groups had no statistical significance(P＞0.05).The univariate analysis indicated that H.pylori infection was not correlated with nationality,permanent residence,occupation,education level,marital status and number of living together members(P＞0.05);H.pylori infection had no correlation with whether the individual or family members having digestive system disease or symptoms(P＞0.05);washing hands before meals and after defecation,stress of work,living and study,mainly used latrine type,daily means of transportation,work and rest time,sharing cutlery,diets habits,brushing teeth frequency per day and source of drinking water had no influence on H.pylori infection(P＞0.05),and smoking,alcohol drinking and frequently contacting with animals also had no influence on H.pylori infection(P＞0.05).H.pylori infection was significanly correlated with the social economical status,daily means of transportation and alcohol drinking(P＜0.05).The multiple unconditional Logistic regression analysis results indicated that there was negative correlation between H.pylori infection and monthly income,the OR (95％CI)value was 0.848(0.759-0.949).Conclusion The H.pylori total infection rate in adult population receiving physical examination in Yunnan plateau area is lower than the national population natural infection rate.It should focus on middle-aged population and low-income people.
ABSTRACT
PURPOSE: Helicobacter pylorus (HP) is a Gram-negative spiral-shaped microaerophilic bacterium, which colonizes in the gastric mucosa of humans. The gastric human pathogen HP causes chronic gastritis and ulcers, and has a strong relationship with gastric cancer. The aim of this study was to determine advanced oxidation protein products (AOPP) levels, activities of myeloperoxidase (MPO) and catalase (CAT) in two groups. MATERIALS AND METHODS: For this aim, one group included 30 patients with gastric cancer (Group 1) and the other included 30 subjects with non-gastric cancer and Anti-HP immunoglobulin (Ig) G antibody positive (group 2). Anti-HP IgG antibody test values were found as positive in fifty percent of group 1 and all of the group 2 patients. RESULTS: Significantly increased AOOP levels were found in group 1 (p < 0.05) compared to group 2. There were no significant differences between the groups in regard to activities of MPO and CAT. In addition, AOPP level, MPO and CAT activities were similar among the Anti-HP IgG positive and negative subgroups of group 1 patients. CONCLUSION: The result of this study indicated that gastric cancer patients were characterized by increased protein oxidation, whereas there was no significant difference in oxidative stress parameters and antioxidant enzyme activity between the Anti-HP IgG positive and negative gastric cancer patients.
