同位素质谱用于医学的最新进展

利用＾１３Ｃ，＾１４Ｃ，＾１５Ｎ等同位素作为示踪剂来探测胃幽门螺杆菌（简称ＨＰ）的试验在近几年有了很大进展，为同位素质谱在医学上的应用开辟了一条新途径。＾１３Ｃ－尿素呼吸试验具有无放射性、无侵害、无污染、对患者无特殊要求等优点，而且方法简便，诊断的正确率达到９３％以上，＾１４Ｃ－尿素呼吸试验的灵敏度很高，准确率达到９６以上（但＾１４Ｃ有轻微的放射性，对孕妇和婴儿应当慎用）。近年来本实验室与医院合作

The Latest Advance in Using Isotope Mass Spectrometry to Solve Medical Science Problems

The test for the detection of Helicobacter Pylon(HP) infection using the isotope 13C, 14C and 15N as a tracer has grealy advanced in recent years. It makes a new way for using isotope to solve medical science problems. The 13C -urea breath test has advantages such as non-invasive,non-radioactive and no pollution. It has no special demand to patients. The method is convenient. The correction rate of diagnosis has been more than 93%. The 14C-urea breath test has a very high sensitivity. Its correction rate has been more than 96%, but 14C has light radiation,it had better not be used in children and pregnant woman. The 15N-urea excretion test is a simple,high sensitive,non-invasive and non-radioactive test. Its correction rate is 96%. It can be popularized in any area which have certain conditions.
