A Participant-assigned Interventional Research of Precesarean Internal Iliac Artery Balloon Catheterization for Managing Intraoperative Hemorrhage of Placenta Previa and Placenta Accreta Spectrum Disorders After Cesarean Section.

Placenta accreta spectrum disorder (PASD) and placenta previa (PP) are two of the most hideous obstetric complications which are usually associated with a history of cesarean section (CS). Moreover, women with PASD, PP and/or a cesarean scarred uterus are more likely to have adverse pregnancy outcomes, including blood transfusion, hysterectomy, pelvic organs damage, postpartum hemorrhage, disseminated intravascular coagulation, multi-organ dysfunction syndrome and even maternal or fetal death. This study aimed to investigate the efficacy of precesarean internal iliac artery balloon catheterization (BC) for managing severe hemorrhage caused by PASD and PP with a history of CS.

Initial-onset symptoms of preeclampsia and their relation to pregnancy outcomes.

Preeclampsia (PE) is a serious gestational idiopathic hypertensive disease, threatening both maternal and foetal safety. As a systemic disease, the initial-onset symptoms (IOSs) and clinical manifestations of PE can vary widely from patient to patient. However, a lack of evidence-based data on IOS and their relationship to their corresponding clinical features and pregnancy outcomes persists.

Variations of plasma D-dimer level at various points of normal pregnancy and its trends in complicated pregnancies: A retrospective observational cohort study.

D-Dimer (DD) is the smallest fragment of plasmin-mediated cleavage of fibrin. There is a progressive increase in DD concentration with advancing gestation in normal pregnancies, making the upper limit of 0.5 μg/ml used in non-pregnant population an unfavorable marker during pregnancy.

Involvement of dysregulated IK and SK channels in preeclampsia.

Introduction: Excessive constriction of placental chorionic plate arteries (CPAs) may be associated with preeclampsia (PE). Nitric oxide (NO) as well as intermediate and small Ca-activated K channels (IK and SK) plays vital roles in vasodilation of CPAs. We hypothesized that dysregulated IK and SK channels may be involved in the pathogenesis of PE mediated by the impaired NO system on CPAs.

Hypoxia downregulates the angiogenesis in human placenta via Notch1 signaling pathway.

Placentation, which is critical for maternal-fetal exchange of nutrients and gases, is a complicated process comprising stepwise vasculogenesis and angiogenesis. Hypoxia caused by impaired trophoblast invasion may cause various angiogenic abnormalities in human placenta. The Notch1 signaling pathway plays an important role in the regulation of angiogenesis.

Establishing a Nomogram for Stage IA-IIB Cervical Cancer Patients after Complete Resection.

Background: This study aimed to establish a nomogram by combining clinicopathologic factors with overall survival of stage IA-IIB cervical cancer patients after complete resection with pelvic lymphadenectomy.

Materials And Methods: This nomogram was based on a retrospective study on 1,563 stage IA-IIB cervical cancer patients who underwent complete resection and lymphadenectomy from 2002 to 2008. The nomogram was constructed based on multivariate analysis using Cox proportional hazard regression.

Up-regulated expression of Tim-3/Gal-9 at maternal-fetal interface in pregnant woman with recurrent spontaneous abortion.

The relationship between T cell immunoglobulin domain and mucin domain protein 3 (Tim-3)/Galectin (Gal)-9 pathway and recurrent spontaneous abortion (RSA) was studied. Thirty-one pregnant women with RSA and 27 normal early gravidas were investigated to detect the levels of Tim-3 and Gal-9 in villi and deciduas by Western blotting. Meanwhile, the concentration of interleukin (IL)-4 and IL-12 in peripheral blood plasma was determined by ELISA in 25 healthy fertile non-pregnant controls, the normal early gravidas and pregnant women with RSA mentioned above, respectively.

HPV16 E5 peptide vaccine in treatment of cervical cancer in vitro and in vivo.

Human papillomavirus (HPV)-induced cervical cancer is the second most common cancer among women worldwide. Despite the encouraging development of the preventive vaccine for HPV, a vaccine for both prevention and therapy or pre-cancerous lesions remains in high priority. Thus far, most of the HPV therapeutic vaccines are focused on HPV E6 and E7 oncogene.

Intrahepatic cholestasis of pregnancy: biochemical predictors of adverse perinatal outcomes.

This study aimed to identify biochemical predictors of adverse perinatal outcomes in intrahepatic cholestasis of pregnancy (ICP). A total of 106 ICP cases were analyzed retrospectively by the combination of receiver operating characteristic curve and binary logistic regression analysis. "Adverse perinatal outcomes" included spontaneous preterm labor, meconium-staining of amniotic fluid, stillbirth and Apgar score ≤7 at 1 or 5 min.

[Effects of human papillomavirus 16 E5 on malignancy of human cervical cancer cells and the mechanism there of].

Objective: The human papillomavirus type 16 (HPV16) early gene (E5) could stimulate cell proliferation and transformation in different ways, and complement or enhancement the function of E6 and E7. It is closely sodiated with the carcinogens of cervical cancer. This study was to investigate the effects of HPV16 E5 on the human cervical cancer cell line SiHa.

[Expression and clinical significance of Pin1 and Cyclin D1 in cervical cancer cell lines and cervical epithelial tissues].

Background & Objective: Peptidyl-prolyl cis/trans isomerase Pin1 is prevalently overexpressed in human cancers. Up-regulation of Pin1 elevates the expression of Cyclin D1, and plays an important role in tumorigenesis and tumor progression. This study was to investigate the expression and clinical significance of Pin1 and Cyclin D1 in cervical cancer cell lines and cervical epithelial tissues.

Area-specific effects of brain-derived neurotrophic factor (BDNF) genetic ablation on various neuronal subtypes of the mouse brain.

The effects of brain-derived neurotrophic factor (BDNF) on the development of presynaptic terminals and of neuronal subtypes in various brain areas were studied in BDNF-knockout (BDNF-/-) mice at postnatal days 15-17. Western analysis revealed no changes in the overall amount of a variety of synaptic proteins in BDNF-/- mice as compared to wild type mice. In addition, the complex between the vesicular proteins, synaptophysin and synaptobrevin, as well as their respective homodimers were unaltered.

Reduced anxiety-related behaviour in transgenic mice overexpressing serotonin 1A receptors.

Serotonergic neurons play a major role in the modulation of emotion and behaviour. Especially knockout studies have revealed a role for the serotonin(1A) (5-HT(1A)) receptor in anxiety related behaviour. Mutant animals exhibit enhanced anxiety-like responses, possibly resulting from impaired autoinhibitory control of midbrain serotonergic neurons.
