PD-related uterine artery blood flow features. (A) Typical images of uterine artery Doppler waveforms from model mice before and after oxytocin injection. (B) The maximum flow velocity (V_max) of the uterine artery. (C) The minimum flow velocity (V_min) of the uterine artery. (D) The average flow velocity (V_mean) of the uterine artery. (E) Resistive index (RI) of uterine artery blood flow. (F) Pulsatility index (PI) of the uterine artery. (G) Velocity time integral (VTI) of uterine artery blood flow. ^# Model group after oxytocin injection compared with the corresponding model group before oxytocin injection. ^# p < 0.05; ^## p < 0.01. * p < 0.05; ** p < 0.01. ns, no significance.
