糖类抗原199(Carbo hydrate Antigen 199,CA199)属低聚糖肿瘤相关抗原,为一种新的肿瘤标志物。近年来,已有多篇文献报告,该项目的检测对消化系统的肿瘤诊断、监视具有一定的临床实用价值,却优于AFP。本文报告乙型肝炎患者血清中糖类抗原199的检测结果,并探讨其临床应用价值,现报告如下。 对象和方法 一、对象: (一)正常人:35人。选自本院健康体检合格的正常人,肝、肾功能试验正常,乙肝病毒血清学标志为阴性、抗-HCV为阴性。 (二)乙肝组:91人。均为临床上明确诊断的住院患者,按1984年(南宁)全国传染病与寄生虫病学术会议制定的乙肝标准分型,乙肝病毒血清学标志为阳性。 二、方法: (一)标本采集:空腹静脉采血后,分离血清,-20℃保存,一周内测定完毕。 (二)试剂盒:CA199试齐盒购自美国公司,操作按说明书。所用仪器为GC-199全自动γ计数器,专人操作,自动打印测量结果。 结果 一、正常人与各型乙肝患者血清CA199测定含量的变化见表1。
Carbohydrate Antigen 199 (CA199) is an oligosaccharide tumor-associated antigen and is a new tumor marker. In recent years, there have been many articles reported that the detection of the project on the digestive system cancer diagnosis, monitoring has a certain clinical value, but better than AFP. This paper reports the detection of hepatitis B patients with serum carbohydrate antigen 199 and explore its clinical value, are as follows. Objects and methods First, the object: (a) normal: 35 people. Normal subjects selected from our health examination, normal liver and kidney function tests, serological markers of hepatitis B virus was negative, anti-HCV is negative. (B) hepatitis B group: 91 people. All were diagnosed clinically inpatient, according to the 1984 (Nanning) National Conference on Infectious Diseases and Parasitic Diseases developed hepatitis B standard typing, hepatitis B serological markers as positive. Second, the method: (A) specimen collection: fasting venous blood, the serum was isolated, stored at -20 ℃, the determination was completed within a week. (B) kit: CA199 test kit purchased from the United States company, according to the instructions. The instrument used is the GC-199 automatic gamma counter, hand operation, automatically print the measurement results. The results of a normal and various types of hepatitis B patients serum CA199 measured content changes in Table 1.
