摘要： 目的通过分析儿童肾病综合征（NS）患者血清游离脂肪酸（NEFA）和白蛋白（ALB）的水平，探讨急性期和恢复期NS患儿 血清NEFA/ALB比值的变化及差异。方法分别测定急性期NS患儿55例、恢复期NS患儿33例和健康对照儿童122例的血清 NEFA、ALB水平，计算NEFA/ALB比值，同时分析其它血脂及肾功能参数水平。结果与健康对照组相比，NS患儿血清ALB （t=11.152，P<0.001）水平显著降低，NEFA/ALB比值（t=4.991，P<0.001）显著升高；其中，急性期患儿较恢复期患儿血清ALB（Z= 7.822，P<0.001）水平显著降低，NEFA/ALB比值（t=4.689，P<0.001）显著升高。相关性分析显示，NS患儿血清NEFA/ALB比值 与胆固醇（r=0.564，P<0.001）、甘油三酯（r=0.444，P<0.001）、低密度脂蛋白（r=0.625，P<0.001）、尿素（r=0.437，P<0.001）、肌酐（r= 0.278，P=0.013）、尿酸（r=0.397，P<0.001）水平均呈显著正相关，与总蛋白（r=-0.461，P<0.001）水平呈显著负相关。逐步多元线 性回归分析显示，在校正其他相关因素的影响下，NS患儿血清NEFA/ALB比值与尿素水平呈显著独立相关（β=0.703，P=0.001； 校正R2=0.494）。结论儿童NS患者血清NEFA/ALB比值显著升高，与其肾功能损伤密切相关，有望作为其临床病情评估的新 指标。

Abstract: Objective To analyze serum levels of non-esterified fatty acids (NEFA) and albumin (ALB) in children with nephrotic syndrome (NS) and investigate the clinical significance of altered serum NEFA to ALB ratio in children with NS in acute and remission phases. Methods Serum levels of NEFA and ALB were measured in 55 NS children in acute phase, in 33 NS children in remission and in 122 healthy control children, and the ratio of NEFA to ALB was calculated. The other lipid/ lipoprotein and renal function parameters were also analyzed in these children. Results Compared with the healthy control children, children with NS had a significantly decreased serum ALB level (t=11.152, P<0.001) and a significantly increased NEFA to ALB ratio (t=4.991, P<0.001). Compared with NS children in remission, those in acute phase showed a significantly decreased ALB (Z=7.822, P<0.001) and an increased NEFA to ALB ratio (t=4.991, P<0.001). In all the NS children, NEFA to ALB ratio was positively correlated with the levels of TC (r=0.564, P<0.001), TG (r=0.444, P<0.001), LDL-C (r=0.625, P<0.001), urea (r= 0.437, P<0.001), creatinine (r=0.278, P=0.013), and uric acid (r=0.397, P<0.001), while negatively correlated with the level of total protein (r=-0.461, P<0.001). Multiple linear regression analyses showed that NEFA to ALB ratio was independently associated with serum urea levels (β=0.703, P=0.001; adjusted R2=0.494) after adjustment of other related factors. Conclusion Serum NEFA to ALB ratio is significantly increased in NS children in close association with impaired kidney function, and may function as a novel parameter for assessing the development of NS.
