①目的探讨血清脂质结合唾液酸（ＬＳＡ）含量对白血病诊断的意义。②方法用唾液酸快速诊断法测定４０例白血病病人及６０例健康人血清ＬＳＡ含量，对所得结果进行了比较，并观察了外周血白血病细胞数与ＬＳＡ的相关关系。③结果白血病病人血清ＬＳＡ含量明显高于对照组，两者差异有极显著性（ｔ＝４．４４，Ｐ＜０．００１），白血病细胞数和骨髓增生程度与ＬＳＡ含量均无明显相关关系（ｒ＝０．１７，－０．１３，Ｐ均＞０．０５）。④结论血清脂质结合唾液酸测定是诊断白血病的一个重要的辅助指标。
Objective To investigate the significance of serum lipid-associated sialic acid (LSA) content in the diagnosis of leukemia. 2 Methods LSA levels in serum of 40 patients with leukemia and 60 healthy persons were measured by sialic acid rapid diagnostic method. The results were compared, and the correlation between peripheral blood leukemia cell number and LSA was observed. 3 Results Serum LSA levels in patients with leukemia were significantly higher than those in the control group. There was a significant difference between the two groups (t = 4.44, P < 0.001), and there was no significant correlation between the number of leukemia cells and the degree of myelodysplasia and LSA. r = 0.17, -0.13, P > 0.05). 4 Conclusions Serum lipid-binding sialic acid assays are an important auxiliary indicator for the diagnosis of leukemia.
