研究目的: |
幽门螺杆菌感染( Hp)是慢性胃炎、消化性溃疡及胃癌的重要致病因素,根除治疗可有效预防消化性溃疡及胃癌的发生发展,但大量广谱抗生素的使用可能破坏肠道菌群稳态,进而引发代谢紊乱、免疫失调等远期健康风险。本研究拟针对北京地区 Hp 感染高发人群,通过多组学整合分析,系统揭示根除治疗前后肠道菌群的动态演变规律及其与临床预后的关联机制。课题计划纳入 60 例 Hp 阳性作为实验组、 20 例 Hp 阴性作为对照组,应用宏基因组学、代谢组学、转录组学及蛋白质组学技术,分析幽门螺杆菌感染患者肠道微生态改变情况,明确 Hp 感染患者肠道菌群组成、功能的特征及代谢产物、黏膜免疫基因表达、宿主蛋白质变化,探讨 Hp 导致肠道菌群改变的发病机制,构建菌群-宿主多维互作网络。同时采用机器学习模型筛选预测根治疗效及不良反应(腹泻、耐药性)的关键微生物标志物,并解析抗生素影响下肠道菌群生态系统的重建规律。 |

Objectives of Study: |
Helicobacter pylori infection is a major pathogenic factor in chronic gastritis, peptic ulcers, and gastric cancer. Eradication therapy effectively prevents the development of peptic ulcers and gastric cancer. However, the extensive use of broad-spectrum antibiotics can disrupt gut microbiota homeostasis, leading to long-term health risks such as metabolic and immune disorders. The study enrolled 60 patients with H. pylori infection in the experimental group and 20 H. pylori-negative patients in the control group. Using metagenomic, metabolomics, transcriptomics, and proteomics techniques, the study analyzed changes in the gut microbiome in patients with H. pylori infection. The study aimed to characterize the composition and function of the gut microbiota, as well as changes in metabolites, mucosal immune gene expression, and host proteins. The study also investigated the pathogenesis of H. pylori-induced gut microbial alterations and constructed a multidimensional network of microbiota-host interactions. At the same time, machine learning models are used to screen key microbial markers that predict radical treatment efficacy and adverse reactions, and to analyze the reconstruction rules of the intestinal flora ecosystem under the influence of antibiotics. |
