目的 探讨泌尿系统肿瘤患者血清唾液酸 (SA)水平。方法 采用化学显色一步法测定 2 0例泌尿系统肿瘤患者血清SA含量 ,并与泌尿系统常见病组患者血清SA对照。结果 肿瘤组SA含量显著高于对照组 ,两组有显著性差异(P <0 .0 0 1)。肿瘤组患者血清SA阳性率为 80 % ,对照组患者血清SA阳性率为 2 0 % ,两组之间有显著性差异 (P <0 .0 0 1)。结论 血清SA测定可作为泌尿系统肿瘤诊断和随访监视的指标之一
Objective To investigate the serum sialic acid (SA) level in patients with urinary system tumors. Methods The content of SA in serum of 20 patients with urinary system tumors was determined by one-step chemical colorization method and compared with the serum SA of patients with common urological diseases. Results The content of SA in the tumor group was significantly higher than that in the control group, with significant difference between the two groups (P <0.01). The positive rate of serum SA in tumor patients was 80%, while the positive rate of serum SA in control patients was 20%. There was a significant difference between the two groups (P <0.01). Conclusion Serum SA assay can be used as one of the indicators of urological diagnosis and follow-up surveillance
