CD34 ,a marker of microvessel, was selected to measure microvessel density (MVD) in the endometrium.Fifteen women who were found to have no condition with normal menstrual cycles were set as control group.Results VEGF immunoreactivity in glandular epithelia cells was significantly lower in the hyperplastic endometrium than that of controls(P ＜ 0. 05). There was no significant difference in VEGF protein level between proliferative DUB endometrium and that of controls. A positive correlation was found between glandular VEGF and MVD in the endometrium(r=0. 666, P＜0.05). Conclusion The anovulatory DUB is associated with down-regulation of VEGF in the endometrium, and decreased secretion of VEGF will result in the disruption of angiogenesis, as a clinical manifestation of irregular bleeding.展开更多

The rates for rapidly controlling bleeding and for rapidly stopping bleeding in E2 group were higher than those in CEE group ,but similar to those in COCs group. The days for controlling and completely stopping bleeding were not significantly different between the starting dosages (≤8 mg/d and >8 mg/d) of E2 groups, and also there were no statistical difference between the starting dosages (<7.5 mg/d and ≥7.5 mg/d) of CEE groups, but during the treatment the rate of increasing the dosage in <7.5 mg/d group was higher than that of ≥7.5 mg/d group(40% vs. 5%),while there were no statistical difference between the starting dosages (≤3 pills/d and >3 pills/d) of COCs groups. Conclusions: The clinical efficiency of E2 treatment on DUB in adolescent patients is similar to that of COCs. And the efficacies of treatment of DUB with E2, CEE and COCs in the different dosages are similar.展开更多
