Objective To investigate the effects of umbilical artery hemodynamic indexes, blood lipids and thyroid stimulating hormone (TSH) on delivery outcomes in patients with gestational diabetes mellitus. Methods A total of 138 patients with gestational diabetes mellitus who were admitted to our hospital from January 2021 to November 2021 were selected and divided into a control group and a study group by random digital table, with 69 cases in each group. The differences in umbilical artery hemodynamic indexes, blood lipid indexes and TSH-related indexes and pregnancy outcomes were compared between the two groups, and multiple linear regression analysis was used to explore the relationship between umbilical artery hemodynamic indexes, blood lipid indexes, TSH, other related indexes and adverse pregnancy outcomes in patients with gestational diabetes mellitus. Results The systolic and diastolic peak volume ratio (S/D), resistive index (RI) of umbilical artery, triglyceride (TG), low density lipoprotein (LDL) and TSH in the study group were higher than those in the control group, while the levels of free triiodothyronine (FT3) and free thyroxine (FT4) were lower than those in the control group (P<0.05). The incidences of macrosomia, cesarean section, neonatal hypoglycemia and neonatal weight in study group were significantly higher than those in the control group (P<0.05). The multiple linear regression equation showed that the adverse pregnancy outcomes were correlated with changes of TG, TSH, RI, S/D, LDL levels (R²=0.224, adjusted R²=0.201; F=9.504, P<0.05), in descending order. Conclusions Abnormal levels of S/D, RI, TG, LDL, TSH and FT4 in pregnant women with gestational diabetes mellitus may affect the pregnancy outcomes. Clinical intervention measures can be taken by monitoring the changes of the above indicators.

目的 分析宫颈弹性成像(UE)参数在宫颈机能不全(CIC)孕妇妊娠结局中的预测价值。方法 选取我院收治的119例(2019年10月—2021年8月)CIC孕妇,根据妊娠结局分为早产组(孕周＜37周)56例、正常组(孕周≥37周)63例,均于孕20～24周接受阴道超声、宫颈UE检查,获取宫颈长度(CL)、宫颈UE参数[超声弹性对比指数(ECI)、宫颈外口弹性应变率(EOS)、宫颈内口弹性应变率(IOS)]并进行比较,以了解宫颈UE参数在CIC孕妇妊娠结局中的应用价值。结果 早产组CL水平较正常组低,ECI、IOS、EOS水平较正常组高(P＜0.05);单因素分析发现,CL、ECI、IOS、EOS均可对CIC孕妇妊娠结局产生影响(P＜0.05);受试者工作特征(ROC)曲线结果显示,CL、ECI、EOS、IOS预测CIC孕妇早产的AUC分别为0.616、0.765、0.728、0.814,敏感度分别为64.29%、75.00%、73.21%、82.14%,特异度分别为42.86%、52.38%、57.14%、42.86%。结论 宫颈UE参数能有效反映宫颈组织情况,对CIC孕妇妊娠结局具有一定的预测价值。
