Objective To explore the risk factors related to postoperative recurrence of uterine fibroid following myomectomy.Methods Four hundred and seventy-three uterine fibroid patients underwent myomectomy were recruited in the case-control study.Leiomyoma characteristics,surgical approach,pathological type and follow-up information were collected by questionnaire.Data were analyzed by correlation analysis and multivariate conditional logistic regression analysis.The calculation of the risk factors associated with the degree of the recurrence after myomectomy was OR and its 95％ confidence interval (95％ CI).Results Among patients,194 cases with recurrence were detected after the 2-7 years follow-up.The number of fibroid removed was the risk factor of postoperative recurrence (OR =2.31,95％ CI:1.57-3.40,P =0.000).Compared with the single fibroid,the risk of recurrence increased 2.31 times in those patients who removed more than two fibroids.Preoperative parity was the protective factor for recurrence (OR =0.63,95％ CI:0.48-0.84,P =0.002).Neither age nor surgical approach or pathological type was associated with the risk of postoperative recurrence related to uterine fibroid following myomectomy.Conlcusion Fibroid number was the risk factor of postoperative recurrence while the preoperative parity was the protective factor.Laparoscopic myomectomy,cellular leiomyoma and muscle intramural leiomyoma did not increase the risk of recurrence.

Objective To investigate the pathogenesis role of aquaporin 3 and aquaporin 9 in idiopathic polyhydramnios by detecting their expression and distribution in fetal membranes and placenta.Methods Twenty-one of term pregnancy women with idiopathic polyhydramnios were enrolled as patient group matched with 30 women with normal term pregnancy as control group.The expression and localization of aquaporin 3 and aquaporin 9 in fetal membranes and placenta were detected by real-time polymerase chain reaction and streptavidin peroxidase immunohistochemiscal staining.Results (1)The mRNA expressions of aquaporin 3 and aquaporin 9 were detected in amnion,chorion and placental tissue in both patient group and control group.Both aquaporin 3 and aquaporin 9 were demonstrated positive staining in the amnion epithelia,chorion cytotrophoblasts and placental trophoblast.(2)The ratio of aquaporin 3 and aquaporin 9 mRNA expressions in amnion in patient group comparing to those in control group were 5.00 and 3.25,while in chorion they were 2.03 and 2.08.When compared with those in amnion and chorion of control group,there was a significant difference(P<0.01).However,the relative change fold of aquaporin 3 and aquaporin 9 in placental trophoblast in patient group were decreased in comparison of those in control group,which also showed statistical difference(P<0.01).(3)The expression of aquaporin 3 and aquaporin 9 protein in anmion were 7.5 ±2. 0 and 11.1 ± 1.8 in patient group, while they were 5.3 ± 1. 6 and 5.6 ± 2. 3 in control group. In chorion, the expression of aquaporin 3 and aquaporin 9 protein was 7.5±2. 0 and 10. 0 ±1.6 in patient group, respectively, while in control group, they were 5.4 ±2.2 and 5.6±2. 1. When compared with those proteins in control group, it exhibited statistical difference (P<0.05). However, in placental trophoblast of patient greup,the expression of aquaporin 3 and aquaporin 9 protein were 3.5±1.4and 4. 0±2. 5, respectively, which were significantly decreased than 5.6±1. 3 and 7. 1±2. 9 in control group(P< 0. 05). Conclusions The alterations of aquaporin 3 and aquaporin 9 expressions in fetal membrane and placenta might be an adaptive response to idiopathic polyhydramnios. Further investigation should be needed to clarify the regulatory mechanism of aquaporin 3 and aquaporin 9 expressions.
