The Research of Feasibility and Efficacy of Radiofrequency Ablation in Treating Uterine Fibroids.

To explore the feasibility and efficacy of radiofrequency ablation in treating uterine fibroids.Ninety patients with multiple uterine fibroids, who had undergone hysterectomy were included in the study. After the uterus was resected, the temperature of 60, 80, 100°C were adopted to ablate the in vitro fibroid with each temperature dealing with 30 patients.

Role of Slit2/Robo1 in trophoblast invasion and vascular remodeling during ectopic tubal pregnancy.

Introduction: For ectopic tubal pregnancy to be viable, it requires a supporting vascular network and functioning trophoblast. Slit2/Robo1 signaling plays an important role in placental angiogenesis during normal pregnancy. Hence, we here investigated whether or not Slit2/Robo1 signaling also had an impact in ectopic tubal pregnancy.

IKKβ/NF-κB mediated the low doses of bisphenol A induced migration of cervical cancer cells.

Cervical cancer is considered as the second most common female malignant disease. There is an urgent need to illustrate risk factors which can trigger the motility of cervical cancer cells. Our present study revealed that nanomolar concentration of bisphenol A (BPA) significantly promoted the in vitro migration and invasion of cervical cancer HeLa, SiHa, and C-33A cells.

Analysis of feasibility of in vitro nuclear magnetic resonance tracking human umbilical cord mesenchymal stem cells by Gd-DTPA labeled.

Objective: Three different kinds of transfection reagents were used to mediate the transfection of gadolinium-diethylenetriamine penta-acetic acid (Gd-DTPA) into human umbilical-cord-derived mesenchymal stem cells (hUCMSCs). The efficacy of different transfection reagents and the feasibility of NMR tracer in vitro of magnetized stem cells were estimated.

Methods: After purification by tissue explants adherent method, the biological characteristics of hUCMSCs in vitro were identified by subculture and amplification.

[Study on human umbilical cord mesenchymal stem cells transplantation in treatment of stress urinary incontinence in rats].

Objective: To investigate the feasibility and effectiveness of human umbilical cord mesenchymal stem cells (HUCMSC) transplantation in the treatment of female stress urinary incontinence (SUI) in rats.

Methods: The 14 female SD rats of SUI model were established by vaginal balloon dilation after birth and maintain this status for four hours bilateral ovariectomy were performed after two weeks and were routinely reared for two months, then 12 SUI rat model were made. Two months later, transfected with plasmid pEGFP-N1 of HUCMSC were injected into the region surrounding the urinary tract matched with saline injection as control group.

XRCC1 polymorphisms are associated with cervical cancer risk and response to chemotherapy: a systematic review and meta-analysis.

Background: Functional single nucleotide polymorphisms of x-ray repair cross-complementing protein 1 (XRCC1) have been suspected to contribute to uterine cervical cancer risk for a long time; however, most previous case-control studies were small sized and biased. Additionally, recent studies suggested that XRCC1 polymorphisms could be a biomarker of response to platinum-based chemotherapy.

Methods: A comprehensive search was conducted to retrieve eligible studies and odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated to measure association strength.

Late gestational maternal serum cortisol is inversely associated with fetal brain growth.

To analyze the association between fetal brain growth and late gestational blood serum cortisol in normal pregnancy.Blood total cortisol was quantified at delivery in 432 Chinese mother/child pairs. Key inclusion criteria of the cohort were: no structural anomalies of the newborn, singleton pregnancy, no alcohol abuse, no drug abuse or history of smoking no hypertensive disorders and no impairment of glucose tolerance and no use of steroid medication during pregnancy.

[Changes of collagen content in uterine ligaments of perimenopausal women with relaxation of pelvic supports].

Objective: To investigate the changes in histological characteristics and collagen content in uterosacral and cardinal ligaments of perimenopausal women in relation to relaxation of pelvic supports.

Methods: Twenty-eight subjects undergoing hysterectomies were selected, in which 14 cases were perimenopausal women with relaxation of pelvic support as the relaxation group and 14 women at perimenopausal age with leomyoma, cervical cancer, adenomyosis as the control group. Samples of cardinal ligaments and uterosacral ligaments were obtained at hysterectomies, and the tissues were sliced and stained by Masson's trichrome technique.
