本文给出了一种通过测试血清以区分健康人和胃癌患者的方法。以488.0nm和514.5nm的激光为光源照射血清,胃癌患者的血清光谱位移大于12nm并且光谱的C峰的相对强度很弱。萎缩性胃炎患者的血清光谱的荧光峰值的强弱和健康人的相似,荧光峰相对值大于0.1;而荧光光谱的位移和癌患者的相似。由此诊断方法所判别的结果与临床诊断结果85.6%是一致的。 This article presents a way to test serum to distinguish between healthy and gastric cancer patients. Serum was irradiated by 488.0 nm and 514.5 nm laser light sources. The serum spectral shift of gastric cancer patients was greater than 12 nm and the relative intensity of the C peak of the spectrum was weak. Atrophic gastritis in patients with serum fluorescence peak intensity and healthy people similar fluorescence peak relative value greater than 0.1; and the displacement of the fluorescence spectrum and cancer patients are similar. The result of this diagnostic method is consistent with the clinical diagnosis of 85.6%.
