diameter and anteroposterior diameter of uterine,uterine volume,and ovarian volume. The girls were divided into the non⁃CPP group
and the CPP group according to the results of GnRH stimulation test. Statistical software was used to analyze and integrate relevant
data. Results:①The level of the uterine artery PI in the CPP group was significantly lower than that in the non⁃CPP group,while
uterine long diameter as well as the level of morning urine LH in the CPP group were significantly higher than those in the non⁃CPP
group(P < 0.05). ②Correlation analysis showed that uterine artery PI was negatively correlated with morning urine LH,morning urine
FSH,long diameter,transverse diameter,anteroposterior diameter of uterine,uterine volume,ovarian volume,and serum LH peak value
(P < 0.05),but had no significant correlation with serum FSH peak value(P > 0.05). Uterine long diameter was positively correlated
with morning urine LH,morning urine FSH,uterine transverse diameter,anteroposterior diameter,uterine volume,ovarian volume,and
serum LH peak value(P < 0.05),but had no significant correlation with serum FSH peak value(P > 0.05). Morning urine LH level was
positively correlated with morning urine FSH,uterine long diameter,transverse diameter,anteroposterior diameter,uterine volume,
ovarian volume,serum LH peak and FSH peak(P < 0.05). ③The area under curve(AUC),sensitivity and specificity of ROC curve
when uterine artery PI,uterine long diameter,and morning urine LH were used for diagnosing CPP in girls were 0.915,76%,90%;
0.945,95% ,88% ;0.925,91% ,84% ,respectively. When uterine artery PI,uterine long diameter,and morning urine LH were
combined in the diagnosis of CPP in girls,the AUC,sensitivity and specificity were 0.974,98% and 90%,respectively,which was
better than used alone. Conclusion:The combined determination of uterine artery PI,uterine long diameter and morning urine LH
display the highest efficacy in the diagnosis of CPP in girls,and has the advantages of safety,non⁃invasive and convenient,which is
suitable for clinical application.
