The baseline characteristics of the cohort were compared by NAf LD status. Linear regression analysis and stepwise multiple regression analysis were applied to assess the risk factors for NAf LD. Receiver operating characteristic curve was used to determine the sensitivity and specificity of Af U in the diagnosis of NAf LD.RESULTS: The prevalence rates of NAf LD and metabolic syndrome(met S) were 38.0% and 25.4%, respectively. The NAf LD group had significantly higher Af U levels than the non-NAf LD group(28.7 ± 7.9 U/L vs 26.0 ± 7.3 U/L, P < 0.001) and the prevalence rate of NAf LD increased with progressively higher serum Af U levels. Af U was positively correlated with met S and its five components: central obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol, and elevated blood pressure and fasting glucose. Stepwise multiple logistic regression analysis showed that Af U was associated with an increased risk of NAf LD(OR = 1.009, 95%CI: 1.003-1.014, P < 0.001). The best cut-off value of Af U for the diagnosis of NAf LD was 27.5 U/L. The area under the curve(diagnostic efficacy index) was 0.606. The sensitivity and specificity were 54.6% and 61.8%, respectively. CONCLUSION: Af U level is significantly associated with NAf LD, and elevated Af U level is an independent risk factor for NAf LD.展开更多

The results showed that the sensitivity and specificityfor the diagnosis of HCC were 81.2% and 83. 3% respectively with the assay of serum AFU activi-ty, and sensitivities in the diagnosis of AFP-negative and early HCC were 76.1% and 70. 8%,respectively. The AFU activity in the HCC tissues and their pericancerous liver tissues was twice asmuch as controls, and consisted with their serum AFU activity (r=0. 742, P【0.01). It is sug-gested that AFU could be a new biologic marker of HCC and have an important value in thediagnosis of HCC.展开更多
