目的通过检测患者血清、腹水 β2 -微球蛋白以评估其临床价值。方法将 6 6例患者分为漏出组、炎症渗出组、恶性肿瘤组 ,同时抽取静脉血和腹水 ,应用放射免疫法测定它们的 β2 -微球蛋白的含量。结果三组之间血清无显著性差异。腹水 :炎症渗出组与漏出组及恶性肿瘤组有显著性差异 ,漏出组与恶性肿瘤组无显著性差异。腹水 -血清梯度三组之间有显著性差异。结论腹水 -血清梯度有助于良恶生腹水的鉴别诊断
Objective To evaluate the clinical value of β2-microglobulin in patients’ serum and ascites. Methods Sixty-six patients were divided into the leakage group, the inflammatory exudation group, and the malignant tumor group. At the same time, venous blood and ascites were collected. Their β2-microglobulin content was determined by radioimmunoassay. Results There was no significant difference in serum levels between the three groups. Ascites: There was a significant difference between the inflammatory exudate group and the leakage group and the malignant tumor group. There was no significant difference between the leakage group and the malignant tumor group. There were significant differences between ascites and serum gradients in the three groups. Conclusion Ascites-serum gradient is helpful for the differential diagnosis of benign and malignant ascites
