根据伟大领袖和导师毛主席关于“预防为主”,“把医疗卫生工作的重点放到农村去”以及中央领导同志“癌症是一种常见病,我国医学一定要战胜它”的指示。我们着手研究能应用于普查的可靠、简易,迅速的癌症生化诊断方法,以期早期发现癌症,及时治疗。目前,在诊断癌症的生化方法中,大多数是测定血液中糖蛋白含量的变化; According to the great leader and mentors Chairman Mao on “prevention as the main” and “putting emphasis on medical and health work in rural areas” and the central leadership’s comrades, “cancer is a common disease, our country’s medicine must overcome it.” We set out to investigate a reliable, simple, and rapid method of biochemical cancer diagnosis that can be applied to census so as to detect cancer early and treat it promptly. At present, most of the biochemical methods for diagnosing cancer are the changes of the glycoprotein content in blood.
