生物化学早就和胃癌诊断打上交道,例如在1845年就有人演示胃癌病人呕吐物中没有酸,而近年生物化学更有了突飞的进展,胃癌诊断在生物化学方面的近况又是怎样的呢?蛋白质蛋白质是生命的物质基础。蛋白质的分离技术和分析方法,近年都有很大的进步。肿瘤组织里或病人的体液中,是否存在肿瘤所固有的特殊的蛋白质呢?寻找这种特殊蛋白质从而作为肿瘤诊断之用,这样的 Biochemistry has long been associated with the diagnosis of gastric cancer. For example, in 1845, some people demonstrated that there was no acid in the vomit of patients with gastric cancer. In recent years, biochemistry has made more rapid progress. What is the status of the diagnosis of gastric cancer in terms of biochemistry? Protein protein is the material basis of life. Protein separation techniques and analytical methods have made great progress in recent years. Is there any special protein that is inherent to the tumor in the tumor tissue or in the patient’s body fluid? Looking for this particular protein can be used as a tumor diagnosis.
