【摘要】 目前通过血浆检测诊断癌症的研究多为使用医学肿瘤标记物来测定,而通过光谱技术对其进行研究的不多。文章运用分光光度计对正常人与食管癌患者的血浆进行光谱检测,通过紫外吸收谱的参数统计与分析,发现两者的差异,为诊断食管癌提供了新的途径。更多还原

【Abstract】 There are too many articles about diagnosing cancers by the content of tumor chemical signs in plasma,but there are few articles about diagnosing them by spectroscopy.The present article belongs to the few.The authors can differentiate the normal and malignant esophagus by the statistic and analysis of absorption spectra after their plasmas are detected by spectrophotometry,which provide a new approach to quickly diagnosing malignant esophagus.更多还原
