中文摘要:
在胃的殖民与胃的癌症的发展和基因的基因变化有关的 H.pylori 导致的客观发炎在回答修改的免疫者包含了主人反应到感染。这研究的目的是评估是否在像使用费的受体的多型性 4 (TLR4 ) 基因,天生、适应的免疫的一个关键管理者,与到在一张中国人口的胃的癌症的危险性有关。方法在 TLR4 的 5 鈥 ? flanking 区域的二个变化(rs1927914 T > C 和 rs10759932 T > C ) 是由使用 PCR 限制碎片长度多型性(RFLP ) 的 genotyped 在 1,053 事件的盒子控制研究的试金在一张中国人口的胃的癌症盒子和 1,100 没有癌症的控制。带 rs10759932 的 C 等位基因的结果个人有胃的癌症的显著地减少的风险(调整或 = 0.81;95%CI = 0.67-0.96 ) 与野类型的同质接合体(TT ) 相比,并且保护的效果不在亚群之中是显著地不同的到年龄成层,性别,吸烟,喝酒并且 H.pylori 感染地位(为异质的 P > 0.05 ) 。没有重要协会在这张学习人口在 rs1927914 和胃的癌症风险之间被观察。到 rs10759932 的 C 等位基因替换的 T 可以在一张中国人口在胃的 carcinogenesis 起一个保护的作用的结论。有不同种族人口的大研究被保证证实这些调查结果。
英文摘要:
Objective: Inflammation induced by H.pylori colonization in the stomach is related to the development of gastric cancer and the genetic variations of the genes involved in the immune responses modify the host response to the infection. The aim of this study was to evaluate whether polymorphisms in the toll-like receptor 4 (TLR4) gene, a key regulator of both innate and adaptive immunity, were related to the susceptibility to
