[摘 要] 目的:探讨多普勒子宫动脉成像、盆腔超声辅助晨尿促性腺激素水平在初诊女童中枢性性早熟(central precocious
puberty,CPP)中的应用价值。方法:选取2022年4月—2023年5月就诊于徐州医科大学淮安临床学院儿科的96例性早熟女童
为研究对象,收集患儿一般资料,检测血基础黄体生成素(luteinizing hormone,LH)、卵泡刺激素(follicle stimulating hormone,
FSH)、雌二醇水平,收集晨尿测定LH和FSH水平,检测骨龄,同时进行盆腔多普勒彩超检查评估子宫动脉搏动指数(pulse index,
PI)和子宫长径、横径、前后径,计算子宫容积和卵巢容积等。行促性腺激素释放激素(gonadotropin⁃releasing hormone,GnRH)
激发试验,依据激发实验结果将女童分为非CPP组和CPP组。运用统计软件对相关数据进行分析。结果:①CPP组患儿子宫
动脉 PI 显著低于非 CPP 组,子宫长径、晨尿 LH 均显著高于非 CPP 组(P < 0.05);②相关性分析结果表明,子宫动脉 PI 与晨尿
LH、晨尿 FSH、子宫长径、横径、前后径、子宫容积、卵巢容积、血 LH 峰值呈负相关(P < 0.05),与血 FSH 峰值无显著相关
(P > 0.05);子宫长径与晨尿LH、晨尿FSH、子宫横径、前后径、子宫容积、卵巢容积以及血LH峰值均呈正相关(P < 0.05),与血
FSH峰值无显著相关(P > 0.05);晨尿LH水平与晨尿FSH、子宫长径、横径、前后径、子宫容积、卵巢容积以及血LH峰值、FSH
峰值均呈正相关(P < 0.05);③ROC 曲线分析子宫动脉 PI、子宫长径、晨尿 LH 诊断女童 CPP 的曲线下面积(area under curve,
AUC)、灵敏度和特异度分别为 0.915、76%、90%,0.945、95%、88%,0.925、91%、84%,而子宫动脉PI、子宫长径、晨尿LH联合诊
断女童CPP时,其AUC、灵敏度、特异度分别为0.974、98%、90%,优于单一指标。结论:子宫动脉PI、子宫长径及晨尿LH联合
诊断女童CPP效能最高,且具有安全、无创、便捷等优点,适合临床推广应用。

[Abstract] Objective:To investigate the application value of Doppler uterine artery imaging and pelvic ultrasound combined with
morning urine gonadotropin in the preliminary diagnosis of central precocious puberty(CPP) in girls. Methods:A total of 96
precocious girls admitted to the Department of Pediatrics,Huai’an Clinical College,Xuzhou Medical University from April 2022 to
May 2023 were recruited as the study objects. General data were collected,serum basic luteinizing hormone(LH),follicle stimulating
hormone(FSH),and estradiol levels were examined,morning urine LH and FSH were determined,and bone age was detected. At the
same time,pelvic Doppler ultrasonography was performed to evaluate the uterine artery pulse index(PI),long diameter,transverse
