According to the disease severity, the patients were divided into the mild PE group (99 cases) and the severe PE group (87 cases). A total of 72 healthy pregnant women who underwent antenatal care were selected as the healthy control group. The levels of serum sFlt-1, CXCL16, and LCN-2 before medication were compared among the patients, and the diagnosis and grading value of the above 3 indicators were analyzed.ResultsFor PE patients vs. healthy controls, the levels of sFlt-1 (132.71±14.49 vs. 68.43±9.28 µg/L), CXCL16 (2.15±0.35 vs. 0.61±0.12 µg/L), and LCN-2 (70.81±8.25 vs. 19.22±3.14 µg/L) were all significantly higher in PE patients than in the healthy controls (P<0.05). For severe PE vs. mild PE, the levels of sFlt-1 (142.16±20.23 vs. 124.41±10.36 µg/L), CXCL16 (2.87±0.59 vs. 1.51±0.28 µg/L), and LCN-2 (90.76±10.16 vs. 53.27±6.19 µg/L) in the severe PE group were higher than those in the mild PE group (P<0.05). Receiver operating characteristic curve (ROC) analysis showed that when the cut-off values of sFlt-1, CXCL16, and LCN-2 were 99.65, 1.36, and 0.84 µg/L, respectively, the diagnostic efficacy of PE was the highest. With these cut-off values, the diagnostic sensitivities of sFlt-1, CXCL16, and LCN-2 were 86.67%, 73.33%, and 93.33%, respectively. The specificities of sFlt-1, CXCL16, and LCN-2 were 80.00%, 86.67%, and 60.00%, respectively. The areas under the curves (AUC) of sFlt-1, CXCL16, and LCN-2 were 0.764, 0.769, and 0.831, respectively. When the cut-off values for sFlt-1, CXCL16, and LCN-2 were 135.16, 2.24, and 70.38 µg/L, respectively, the efficacy was the highest in distinguishing mild and severe PE. With these cut-off values, the AUC values of sFlt-1, CXCL16, and LCN-2 were 0.837, 0.808, and 0.869, respectively.ConclusionssFlt-1, CXCL16, and LCN-2 have certain significance in the diagnosis and grading of PE. Among them, LCN-2 has the highest correlation with the diagnosis and grading of PE."xsd:string |
