研究目的: |
通过收集收集200例胃黏肠化患者200例非萎缩性胃炎患者的3块胃黏膜组织、1滴指尖血和10g粪便标本,采用HE染色、免疫荧光、定量聚合酶链反应qPCR、幽门螺杆菌抗体分型检测(免疫印迹法)、C-13呼气试验等方法,检测患者胃粘膜幽门螺杆菌的感染类型与解痉多肽表达化生的严重程度,解析幽门螺杆菌毒力因子CagA与解痉多肽表达化生的关系,为胃黏膜肠化的临床诊断和治疗提供新策略。 |

Objectives of Study: |
Three sections of gastric mucosa tissue, one drop of fingertip blood and 10g stool samples were collected from 100 patients with gastric intestinal metaplasia disease and 100 patients with non-atrophic gastritis. HE staining, immunofluorescence, quantitative polymerase chain reaction (qPCR), Helicobacter pylori antibody typing detection (Western blot), C-13 breath test and other methods were used. To detect the type of Helicobacter pylori (H. pylori) infection in the gastric mucosa and the severity of the expression of antispasmodic peptides, and to analyze the relationship between Helicobacter pylori virulence factor CagA and the expression of antispasmodic peptides, so as to provide a new strategy for the clinical diagnosis and treatment of gastric intestinal metaplasia. |
