Predictive value of excision repair cross-complementing rodent repair deficiency complementation group 1 and ovarian cancer risk.

Objective: We aimed to analyze the association between excision repair cross-complementing rodent repair deficiency complementation group 1 (XRCC1) and ovarian cancer risk.

Methods: We performed a hospital-based case-control study with 155 cases and 313 controls in China. All Chinese cases with newly diagnosed primary ovarian cancer between May 2005 to May 2010 in our hospital were invited to participate within 2 months of diagnosis.

[Effect of levonorgestrel-releasing intrauterine system combined with GnRH analogue for treatment of large adenomyosis].

Objective: To evaluate the effects of levonorgestrel-releasing intrauterine system (LNG-IUS) combined with GnRH analogue (GnRH-a) in the treatment of adenomyosis with uterine body enlargement.

Methods: Twelve women (mane age 40.3 years) with adenomyosis and uterine cavity depth over 11 cm received injections of GnRH-a every 4 weeks, and after the uterine cavity depth was reduced to below 10 cm, LNG-IUS was deployed.

[Expression and methylation of adenomatous polyposis coli gene in endometrioid adenocarcinoma].

Background & Objective: Endometrial carcinoma is a common malignant tumor of female reproductive system, with an increasing incidence in China. Adenomatous polyposis coli (APC) gene, a tumor suppressor gene, is expressed in many tissues, and has a certain relationship with ovarian cancer. This study was to observe the expression and DNA methylation of APC gene in endometrioid adenocarcinoma, and explore its correlations to the occurrence and development of this disease.

Effects of cilostamide and forskolin on the meiotic resumption and embryonic development of immature human oocytes.

Background: In an attempt to allow for acquisition of oocyte cytoplasmic maturation, PDE3 specific inhibitor, cilostamide and adenylate cyclase activator, forskolin were used to extend pre-maturation culture of immature human oocytes.

Methods: Cumulus-oocyte complexes retrieved from unstimulated ovaries were continuously cultured under 20 microM cilostamide or 50 microM forskolin, alone or in combination for 6, 12, 24 or 48 h, respectively. Levels of intercellular gap junction communication (GJC) and maturational status were examined at these designated time points.
