ABSTRACT
Objective:To analyze the evaluation value of changes in β-human chorionic gonadotrophin (β-HCG) for the curative effect of methotrexate (MTX) on ectopic pregnancy (EP).Methods:A retrospective analysis was performed in 80 EP patients who admitted to Jinhua People's Hospital from January 2013 to August 2019.Results:Of the 80 EP patients, success and failure rates of treatment were 77.50% (62/80) and 22.5% (18/80), respectively.According to different treatment results, they were divided into success group (62 cases) and failure group (18 cases). Before treatment, hemodynamic index of fallopian tube artery[resistance index (RI)] in success group was higher than that in failure group ( t=4.150, P<0.05). Before treatment, after 1d, 4d and 7d of treatment, the serum levels of β-HCG in success group were lower than those in failure group ( t=69.496, 76.618, 217.488, 310.203, all P<0.05). The results of Pearson correlation analysis showed that RI was negatively correlated with serum level of β-HCG before treatment, after 1d, 4d and 7d of treatment ( r=-0.374, -0.396, -0.471, -0.482, all P<0.05). The receiver operating characteristic (ROC) curves analysis showed that after 4d and 7d of treatment, areas under the curve (AUC) of β-HCG for evaluating the curative effect of MTX on EP were 0.821 and 0.829, respectively, which were higher than before treatment and after 1d of treatment (0.685, 0.701) ( P<0.05). Conclusion:The changes of β-HCG are of high clinical value in evaluating the curative effect of MTX on EP, which can be applied as an important monitoring index.
