目的 :通过血清中与癌相关的分子标志物的荧光光谱分析 ,探讨在分子、电子水平上的恶性肿瘤的诊断方法。方法 :取癌症患者肘静脉血 ,采用光致发光的方法研究血清中的发光中心 ,观察肌体发生恶性肿瘤以后对原卟啉、类胡萝卜素含量的影响。通过原卟啉对类胡萝卜素的相对含量的测
OBJECTIVE: To investigate the diagnostic methods of malignant tumors at molecular and electronic levels by fluorescence spectroscopy of serum-associated molecular markers. Methods: The elbow venous blood was collected from patients with cancer. The luminescence center in serum was studied by photoluminescence and the effect of protoporphyrin and carotenoid content after malignant tumor was observed. Determination of the relative content of carotenoids by protoporphyrin
