编者按:早在18世纪初,研究人员就发现人呼出气味的不同预示着某些疾病的发生。随着现代医学的发展,呼出气体中有越来越多的疾病相关标志物被发现,最近十几年的研究表明呼出气体中存在可以用于诊断糖尿病、代谢性肥胖、癌症、结核病以及脓毒症等疾病的标志物。在临床应用方面,呼出气检测更是已经成为幽门螺杆菌快速诊断的标准之一。呼出气检测由于其无创检测的优势,可用于疾病的早期发现,病程监测以及预后管理,在临床应用中有着非常巨大的潜力。目前 Editor’s Note: As early as the early 18th century, researchers found that the difference in what people breathe out heralded the onset of certain diseases. With the development of modern medicine, more and more disease-related markers have been found in exhaled gases. More than ten years of researches have shown that there are exsiting gases that can be used to diagnose diabetes, metabolic obesity, cancer, tuberculosis and sepsis Disease and other diseases markers. In clinical applications, exhaled breath detection has become one of the criteria for the rapid diagnosis of Helicobacter pylori. Exhaled gas detection because of its non-invasive detection advantages, can be used for early detection of disease, disease monitoring and prognosis management, has great potential in clinical applications.
