目的:探讨~(14)C尿素呼气试验阳性率的季度分布及应用。方法:收治行幽门螺杆菌检测患者25 200例,入院后对患者采用~(14)C尿素呼气试验检测幽门螺杆菌。结果:2014年4个季度的DMP值低于2013年与2015年(P<0.05)。结论:每年的幽门螺杆菌感染阳性率于第一季度及第四季度较高;DMP值的高低不随季度的变化而呈规律的变化,DMP值的高低不能作为独立诊断消化道疾病的标准。
Objective: To investigate the seasonal distribution of ~ (14) C urea breath test and its application. Methods: A total of 25 200 patients were tested for Helicobacter pylori infection. Helicobacter pylori was detected by ~ (14) C urea breath test after admission. Results: The DMP values for 4 quarters in 2014 were lower than those in 2013 and 2015 (P <0.05). Conclusion: The positive rate of Helicobacter pylori infection in each year is higher in the first quarter and the fourth quarter. The DMP value does not change regularly with the quarterly changes. The DMP value can not be used as a criterion for independent diagnosis of gastrointestinal diseases.
