By some estimates, more than 50% of the world's population is infected by the bacterium Helicobacter pylori, a gastrointestinal pathogen most famous for its role in the development of gastric ulcers. H. pylori infection is also a risk factor for gastric cancer, but because only a small percentage of infected individuals develop the disease, it would be of great interest to identify controllable lifestyle factors that might contribute to an enhanced risk of cancer. Correlative data from epidemiological studies have suggested a potential interaction between H. pylori infection and diet, but long-term human studies that would establish a cause-effect relationship are not feasible. In a carefully controlled 5-year study of Rhesus monkeys that were monitored at frequent intervals by gastroscopy and biopsy, Liu et al. found that gastric neoplasia (precancerous and cancerous lesions) developed in H. pylori–infected animals that had also consumed a carcinogen similar to one found in pickled vegetables and smoked meats,(腌制的蔬菜和烟醺的肉) but not in animals exposed to either the bacterium or the carcinogen alone. In terms of cancer prevention strategies, these findings underscore the importance of dietary awareness in individuals known to be infected with H. pylori. 结论是(我猜):有胃溃疡的人士少吃腌制的蔬菜和烟醺的肉,以免得gastric cancer. 不知道这样zz会不会触犯版权法呢?请知情人士告知。感激涕零。 |
