The efficacy of amniotic membrane-mediated sequential double-barrier therapy for the treatment of postoperative intrauterine adhesions.

To study the efficacy of using amniotic membrane, balloon and intrauterine device (IUD) as barrier therapy to prevent re-adhesion after hysteroscopic adhesiolysis.A total of 45 patients diagnosed with intrauterine adhesions in Changzhou Maternal and Child Health Hospital from June 2014 to December 2017 were included in this retrospective case control study. According to different postoperative isolation barrier methods, the patients were divided into group A (Foley balloon + fresh amniotic membrane Day1 + IUD Day7) (22 cases) and group B (Foley balloon Day1 + IUD Day7) (23 cases).

The antifertility effectiveness of copper/low-density polyethylene nanocomposite and its influence on the endometrial environment in rats.

Purpose: The study was conducted to investigate the antifertility effectiveness of copper/low-density polyethylene nanocomposite (nano-Cu/LDPE) and its influence on the endometrial environment in rats.

Methods: One hundred and seventy sexually mature female Sprague-Dawley (SD) rats were randomly divided into five groups: sham-operated control group (SO group, n=10), bulk copper group (Cu group, n=40), LDPE group (n=40), and nano-Cu/LDPE groups I (n=40) and II (n=40). Twenty rats in each group except for the SO group were mated with male rats of proven fertility, from 30 days after insertion, and the antifertility rates (ATs) were observed at Day 11 of pregnancy.

Effects of antisense oligodeoxynucleotide to follicle-stimulating hormone receptor on the expression of proliferating cell nuclear antigen and vascular endothelial growth factor in primary culture cells derived from human ovarian mucinous cystadenocarcinoma.

The effects of antisense oligodeoxynucleotide (antisense ODN) to follicle-stimulating hormone receptor (FSHR) and follicle-stimulating hormone (FSH) on the expression of proliferating cell nuclear antigen (PCNA) and vascular endothelial growth factor (VEGF) were studied in primary culture cells derived from human ovarian mucinous cystadenocarcinoma (OMC). The primary OMC cells were cultured with the enzyme digestion method, and the expression of pan Keratin protein and FSHR mRNA was detected for identification of the cells. OMC cells were co-cultured with antisense ODN, nonsense ODN and FSH with different concentrations for 48 h and 72 h.
