Objective To provide the normal hemodynamic parameters of uterine several arteries in reproductive women.Methods The hemodynamic parameters including peak systolic velocity(PSV),end diastolic velocity(EDV),resistance index(RI),pulsatility index(PI)and systolic/diastolic velocity ratio(S/D) of uterine artery(UTA),arcuate artery(AA),radial artery(RA)and spiral artery (SA) in 66 reproductive women were studied by transvaginal color Doppler(TVCD).The results were analyzed with T test.Results The flow of uterine several arteries in normal reproductive women was all detected well.From UTA to SA,parameters gradually decreased.In the secretory phase of menstrual cycle,the change of SA which EDV value was higher and RI value was lower was the most obviously.Conclusion The uterine hemodynamics in productive period is in close relalionship with menstrual cycle.We can predict the time of menstrual cycle according RI value of SA.

Objective To explore the value of narrow band imaging combined with endoscopic dentate line in evaluation of patients with gastroesophageal reflux disease.Methods A total of 200 patients with GERD were selected as GERD group and 160 normal people were selected as control group.Gred-Q score was used to record the symptoms.The morphology of the dentate line and microvessel were observed by narrow-band imaging.Gred-Q score,dentate line morphology,the relationship between esophageal microvascular manifestations and gastroesophageal reflux disease were analyzed.Results The abnormal positive rate of NBI microvessel density in GRED group was significantly higher than that in control group (P ＜ 0.05).The abnormal rate of dentate line in GRED group was significantly higher than that in control group (P ＜ 0.05).There were positive correlations between NBI microvessel performance and Gerd-Q score,dentate line morphology and Gerd-Q score,NBI microvessel performance and dentate line morphology (r =0.780,0.803,0.586,P ＜ 0.01).Conclusion Narrow band imaging combined with endoscopic dentate line has an important clinical value in diagnosing patients with gastroesophageal reflux disease.
