Torelli FR, Rodrigues-Peres RM, Lopes-Cendes I, Bahamondes L, Juliato CRT. Gene expression associated with vaginal bleeding in women using the 52-mg levonorgestrel hormonal intrauterine device: A prospective study. Int J Gynaecol Obstet 2024; 165:1199-1209. [PMID: 38299835 DOI: 10.1002/ijgo.15357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 09/27/2023] [Accepted: 12/26/2023] [Indexed: 02/02/2024]
Abstract
OBJECTIVE To evaluate gene expression associated with vaginal bleeding in the 52-mg hormonal intrauterine device (IUD) users. MATERIALS AND METHODS We conducted a prospective study involving 100 women seeking to use the 52-mg hormonal IUD for contraception. We excluded women with a history or current condition of abnormal uterine bleeding and who were unable to attend a 1-year follow up. Women who expelled the device, removed it for reasons unrelated to vaginal bleeding, or were lost to follow up were discontinued. We collected endometrial biopsies immediately before IUD placement and assessed 20 selected genes using reverse transcription quantitative polymerase chain reaction. Users maintained a uterine bleeding diary for 12 months following IUD insertion. For statistical analysis, participants were categorized into groups with or without vaginal bleeding at 3 and 12 months. RESULTS Women with elevated CXCL9 expression had an 8.15-fold higher likelihood of experiencing vaginal bleeding at 3 months (odds ratio [OR] 8.15, 95% confidence interval [CI] 2.24-29.61, P = 0.001). At 12 months of follow up, women with increased TIMP1 expression had a 2.74-fold higher chance of experiencing vaginal bleeding (OR 2.74, 95% CI 1.08-6.95, P = 0.033). CXCL9 ≥ 1.5 and IL17A ≥ 0.68 were associated with a higher probability of vaginal bleeding at 3 months, while TIMP1 levels ≥0.943 were linked to an increased risk of bleeding at 12 months. CONCLUSION Users of the 52-mg hormonal IUD with elevated relative CXCL9 expression face an increased risk of vaginal bleeding at 3-month follow up, whereas those with heightened TIMP1 expression are more likely to experience vaginal bleeding at 12 months.

COVID-19 (SARS-CoV-2) mRNA vaccination does not affect basal sex hormone levels (follicle-stimulating hormone, luteinizing hormone, estradiol) in reproductive-age women. Clin Exp Reprod Med 2024; 51:151-157. [PMID: 38525522 PMCID: PMC11140255 DOI: 10.5653/cerm.2023.06107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 10/25/2023] [Accepted: 11/18/2023] [Indexed: 03/26/2024] Open
Abstract
OBJECTIVE People vaccinated with the coronavirus disease 2019 (COVID-19) (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) mRNA vaccine have reported experiencing various adverse effects. For instance, reproductive-age women have presented with complaints of abnormal uterine bleeding or menstrual cycle changes. We speculated that differences in basal sex hormone levels before and after vaccination may be present in women who experienced irregular bleeding or menstrual cycle changes; thus, this study aimed to investigate the differences in basal sex hormone levels of women before and after two doses of SARS-CoV-2 mRNA vaccination. METHODS This retrospective study included patients who received SARS-CoV-2 mRNA vaccines between January 2021 and February 2022 at a single center. In an outpatient setting, patients were queried regarding their menstrual cycle, the date of SARS-CoV-2 mRNA vaccination, vaccination type, and vaccination side effects. Differences in basal hormone levels (menstrual cycle days 2-3, follicle-stimulating hormone [FSH], luteinizing hormone [LH], and estradiol) before and after vaccination were compared. RESULTS Among the 326 patients, patients with no laboratory records of the hormones were excluded. The median time interval between SARS-CoV-2 mRNA vaccination and the laboratory test day was 79 days (interquartile range, 44 to 127). A comparative analysis of these hormones before and after vaccination revealed no significant differences. Subgroup analyses based on age and reported adverse events also found no statistically significant differences. CONCLUSION This study showed no significant differences in basal hormone levels (FSH, LH, and estradiol) before and after SARS-CoV-2 mRNA vaccination.

Abstract
Reproductive tract bleeding is an underappreciated health care problem among adolescent and young adult (AYA) females with inherited bleeding disorders (IBDs) comprising von Willebrand disease, platelet disorders, hemophilia carriership, and rare factor deficiencies. IBDs are prevalent in women of all ages and have been detected in about 50% of women with menorrhagia or heavy menstrual bleeding (HMB) and about 20% of women with postpartum hemorrhage (PPH). The clinical spectrum of gynecologic and obstetric bleeding in AYA with IBDs ranges from HMB, ovulation bleeding, and surgical bleeding to miscarriages and life-threatening PPH. Reproductive tract bleeding adversely affects the quality of life of this patient population, in addition to causing substantial morbidity and mortality. Early diagnosis of IBDs offers the opportunity for timely intervention with hormones, hemostatic agents, and prophylaxis with factor concentrates, thereby improving outcomes. This review summarizes the epidemiology, pathophysiology, clinical manifestations, diagnostic approach, management, and prophylaxis for reproductive tract bleeding in AYA with IBDs. This review provides a multidisciplinary approach to the problem, which is critical to improve the outcomes of this patient population.

The Plasminogen Activator System, Glucocorticoid, and Mineralocorticoid Receptors in the Primate Endometrium During Artificial Menstrual Cycles. Reprod Sci 2022; 29:1001-1019.

Abstract
As a key mechanism in fibrinolysis and tissue remodeling, the plasminogen activator system has been suggested in the process of endometrial shedding and tissue remodeling. Previous studies have explored the role of estrogen, progesterone, and androgen receptors as well as elements of the renin-angiotensin-aldosterone system in shaping the morphology of the endometrium. This study investigates the distribution and concentrations of the mineralocorticoid receptor, glucocorticoid receptor, tissue plasminogen activator, urokinase plasminogen activator, and plasminogen activator inhibitor-1 within the endometrial stroma, glandular, and endothelial cells of the primate endometrium during artificial menstrual cycles. Our immunohistochemistry quantification shows mineralocorticoid and glucocorticoid receptors are ubiquitously distributed within the macaque endometrium with their patterns of expression following similar fluctuations to urokinase and tissue plasminogen activators particularly within the endometrial vasculature. These proteins are present in endometrial vasculature in high levels during the proliferative phase, decreasing levels during the secretory phase followed by rising levels in the menstrual phase. These similarities could suggest overlapping pathways and interactions between the plasminogen activator system and the steroid receptors within the endometrium. Given the anti-inflammatory properties of glucocorticoids and the role of plasminogen activators in endometrial breakdown, the glucocorticoid receptor may be contributing to stabilizing the endometrium by regulating plasminogen activators during the proliferative phase and menstruation. Furthermore, given the anti-mineralocorticoid properties of certain anti-androgenic progestins and their reduced unscheduled uterine bleeding patterns, the mineralocorticoid receptor may be involved in unscheduled endometrial bleeding.

Diagnostics (Basel) 2021; 11:diagnostics11061094.

Abstract
BACKGROUND AND AIMS Postmenopausal endometrial polyps are commonly managed by surgical resection; however, expectant management may be considered for some women due to the presence of medical co-morbidities, failed hysteroscopies or patient's preference. This study aimed to identify patient characteristics and ultrasound morphological features of polyps that could aid in the prediction of underlying pre-malignancy or malignancy in postmenopausal polyps. METHODS Women with consecutive postmenopausal polyps diagnosed on ultrasound and removed surgically were recruited between October 2015 to October 2018 prospectively. Polyps were defined on ultrasound as focal lesions with a regular outline, surrounded by normal endometrium. On Doppler examination, there was either a single feeder vessel or no detectable vascularity. Polyps were classified histologically as benign (including hyperplasia without atypia), pre-malignant (atypical hyperplasia), or malignant. A Chi-squared automatic interaction detection (CHAID) decision tree analysis was performed with a range of demographic, clinical, and ultrasound variables as independent, and the presence of pre-malignancy or malignancy in polyps as dependent variables. A 10-fold cross-validation method was used to estimate the model's misclassification risk. RESULTS There were 240 women included, 181 of whom presented with postmenopausal bleeding. Their median age was 60 (range of 45-94); 18/240 (7.5%) women were diagnosed with pre-malignant or malignant polyps. In our decision tree model, the polyp mean diameter (≤13 mm or >13 mm) on ultrasound was the most important predictor of pre-malignancy or malignancy. If the tree was allowed to grow, the patient's body mass index (BMI) and cystic/solid appearance of the polyp classified women further into low-risk (≤5%), intermediate-risk (>5%-≤20%), or high-risk (>20%) groups. CONCLUSIONS Our decision tree model may serve as a guide to counsel women on the benefits and risks of surgery for postmenopausal endometrial polyps. It may also assist clinicians in prioritizing women for surgery according to their risk of malignancy.

Abstract
Successful pregnancy and reproduction are dependent on adequate uterine blood flow, placental perfusion, and vascular responsivity to fetal demands. The ability to support pregnancy centers on systemic adaptation and endometrial preparation through decidualization, embryonic implantation, trophoblast invasion, arterial/arteriolar reactivity, and vascular remodeling. These adaptations occur through responsiveness to endocrine signaling and local uteroplacental mediators. The purpose of this article is to highlight the current knowledge associated with vascular remodeling and responsivity during uterine preparation for and during pregnancy. We focus on maternal cardiovascular systemic and uterine modifications, endometrial decidualization, implantation and invasion, uterine and spiral artery remodeling, local uterine regulatory mechanisms, placentation, and pathological consequences of vascular dysfunction during pregnancy. © 2021 American Physiological Society.

Abstract
Endometriosis is a chronic disease, characterized by the growth of endometrial-like cells outside the uterine cavity. Due to its complex pathophysiology, a totally resolving cure is yet to be found. The aim of this study was to compare the therapeutic efficacy of AZD4547, a novel fibroblast growth factor receptor inhibitor (FGFRI), with a well-characterized progestin, etonogestrel (ENG) using a validated in vivo mouse model of endometriosis. Endometriosis was induced by transplanting uterine fragments from donor mice in proestrus into the peritoneal cavity of recipient mice, which then developed into cyst-like lesions. AZD4547 and ENG were administered systemically either from the day of endometriosis induction or 2-weeks post-surgery. After 20 days of treatment, the lesions were harvested; their size and weight were measured and analyzed histologically or by qRT-PCR. Stage of estrous cycle was monitored throughout. Compared to vehicle, AZD4547 (25 mg/kg) was most effective in counteracting lesion growth when treating from day of surgery and 2 weeks after; ENG (0.8 mg/kg) was similarly effective in reducing lesion growth but only when administered from day of surgery. Each downregulated FGFR gene expression (p < 0.05). AZD4547 at all doses and ENG (0.008 mg/kg) caused no disturbance to the estrous cycle. ENG at 0.08 and 0.8 mg/kg was associated with partial or complete estrous cycle disruption and hyperemia of the uteri. AZD4547 and ENG both attenuated endometriotic lesion size, but only AZD4547 did not disrupt the estrous cycle, suggesting that targeting of FGFR is worthy of further investigation as a novel treatment for endometriosis.

Abstract
Drospirenone (DRSP) is a fourth-generation progestin that interacts with the progesterone receptor (PR) and androgen receptor (AR) in addition to uniquely interacting to the mineralocorticoid receptor (MR). The known effects of DRSP via the mineralocorticoid receptor (MR) are limited. This study seeks to determine if DRSP alters plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (tPA) in human immortalized endometrial endothelial cells (HEEC) and if such changes in the plasminogen activator system (PAS) are mediated through the MR or AR. The in vitro cell culture experiments utilizing an immortalized human endometrial endothelial cell line evaluated two concentrations of DRSP on PAI-1 and tPA levels in the culture media using specific enzyme-linked immunoassays (ELISA). Experiments adding DRSP with an androgen receptor blocker, flutamide, or a mineralocorticoid receptor agonist, aldosterone, were performed to elucidate which receptor(s) mediated the PAS effects. DRSP 10 μM significantly decreased both HEEC levels of PAI-1 and tPA to 0.75 ± 0.04 and 0.82 ± 0.05 of control, respectively. These direct effects were blunted by flutamide, an AR antagonist. PAI-1 and tPA were not changed by the MR agonist, aldosterone. DRSP significantly decreased both PAI-1 and tPA in the HEECs via the androgen receptor.

Abstract
OBJECTIVE To study C-X-C motif chemokine 12 (CXCL12) and CXCR4 expression in endometrial tissue from both women with and without abnormal uterine bleeding (AUB) of endometrial origin and evaluate their relationship with microRNA (miRNA). DESIGN Retrospective and laboratory study. SETTING University-based research laboratory. PATIENT(S) Nine women with and without abnormal uterine bleeding, all of whom were in the secretory stage of their menstrual cycle, who provided endometrial biopsy tissue. INTERVENTION(S) Immunohistochemical localization of CXCL12 and CXCR4 as well as quantitative reverse-transcription polymerase chain reaction (qRT-PCR) assessment of mRNA expression in archived endometrial biopsy tissue and in vitro cell culture using the immortalized endometrial stromal cell line, t-HESC. Endometrial stromal cell line, t-HESC transfection with nontargeting, negative control miRNA mimics or miRNA mimics for miR-23b-3p and mRNA assessment miR-23b-3p expression confirmed by qRT-PCR and evaluation of impact on CXCL12 expression at the protein level by enzyme-linked immunosorbent assay and mRNA levels by qRT-PCR. MAIN OUTCOME MEASURE(S) Expression of CXCL12 and CXCR4 protein via immunohistochemistry and mRNA and miRNA levels of CXCL12 and CXCR4 as well as miR-23b-3p, miR-24b-3p, and miR-27b-3p, respectively, via qRT-PCR. RESULT(S) CXCL12 and its receptor CXCR4 expression were up-regulated in the endometrial tissue of women with AUB at the protein level, but this up-regulation of expression was only associated with increased CXCR4 mRNA expression. To evaluate whether CXCL12 may be post-transcriptionally regulated, we assessed expression of miR-23b-3p, a bona fide post-transcriptional regulator of CXCL12 expression. The expression of miR-23b-3p was statistically significantly lower in AUB endometrial tissue, as were fellow cluster members miR-24-3p and miR-27-3p. Transfection of t-HESC cells with pre-miR-23b-3p mimics statistically significantly reduced the levels of CXCL12 secreted protein but not mRNA levels, suggesting that miR-23b-3p retards protein translation independent of transcript degradation. CONCLUSION(S) Reduced expression of the miR-23b-3p/24-3p/27b-3p cluster is associated with elevated expression of CXCL12, which may contribute to the pathophysiology of AUB.

Abstract
AIMS Following the identification of endometrial intravascular thrombi (IVT) as the presenting feature in a patient with antiphospholipid syndrome, additional biopsy specimens were reviewed to determine the frequency and histological associations of IVT in the endometrium. METHODS AND RESULTS Eighty-five additional biopsies were reviewed including 44 consecutive cases demonstrating shedding changes (both menstrual and non-cyclical), 30 cases without shedding (normal and non-cyclical), and 11 cases in which unusually prominent IVT had been recorded upon initial histological assessment. In the shedding group, IVT were significantly more common in biopsies showing disordered proliferative endometrium (DPE, 4/7 cases) than normal menstrual appearances (4/22 cases), and organising vascular changes were seen only in the former. IVT in DPE cases were also commonly multifocal and sometimes involved abnormal ectatic vessels. None of the 30 non-shedding cases demonstrated IVT. Eight of the 11 biopsies with prominent IVT demonstrated DPE and shedding but three cases demonstrated otherwise normal cyclical appearances. CONCLUSIONS IVT may be seen occasionally in normal menstrual endometrium but are more characteristic of DPE, and organising vascular changes are suggestive of abnormal haemostasis. An underlying thrombotic disorder may be considered when endometrial IVT occur in the absence of shedding changes.

Regulation effect and mechanism of Sheng-Hua-Tang on female reproductive system: From experimental transcriptomic analysis to clinical applications. JOURNAL OF ETHNOPHARMACOLOGY 2020; 249:112431. [PMID: 31783136 DOI: 10.1016/j.jep.2019.112431] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Revised: 11/25/2019] [Accepted: 11/25/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sheng-Hua-Tang (SHT) is commonly used to treat female illnesses, especially postpartum conditioning. However, its effects and mechanisms on female reproductive system remain unclear. The aim of the present study was to investigate the effect of SHT on female brain-ovary-uterus axis from bench to clinic. MATERIALS AND METHODS Mice were administrated SHT (200 mg/kg) orally for seven consecutive days. Brain, ovary, and uterus tissues were then collected for microarray analysis. A nationwide database analysis and a pilot randomized, open-label clinical trial were further applied to evaluate the clinical application and effects of SHT on postpartum women. RESULTS Microarray analysis showed that oral administration of SHT induced a cascade reaction of gene expression, with 17, 883, and 1592 genes were significantly regulated by SHT in brain, ovary, and uterus, respectively. Population-based analysis of one million subjects in Taiwan's National Health Insurance Research Database between 1997 and 2013 showed that SHT was commonly used in menstrual disorders in female population, especially dysmenorrhea, abnormal uterine bleeding, and variation of menstrual cycle. Clinical trial on postpartum women showed that oral administration SHT for one week alleviated uterine contraction pain and breast swelling pain. Furthermore, Mmp2, Mmp3, Mmp9, Mmp11, Mmp15, Oxtr, Plrl, and Tph2 gene expression affected by SHT in mice were correlated with clinical effects of SHT in human subjects. CONCLUSION This report provided the scientific evidences of mechanisms and clinical efficacies of SHT. Moreover, our findings might afford insights for clinical doctors in terms of SHT prescription.

Abstract
The embryo of an oocyte donation (OD) pregnancy is completely allogeneic to the mother, which leads to a more serious challenge for the maternal immune system to tolerize the fetus. It is thought that macrophages are essential in maintaining a healthy pregnancy, by acting in immunomodulation and spiral arterial remodeling. OD pregnancies represent an interesting model to study complex immunologic interactions between the fetus and the pregnant woman since the embryo is totally allogeneic compared to the mother. Here, we describe a narrative review on the role of macrophages and pregnancy and a systematic review was performed on the role of macrophages in OD pregnancies. Searches were made in different databases and the titles and abstracts were evaluated by three independent authors. In total, four articles were included on OD pregnancies and macrophages. Among these articles, some findings are conflicting between studies, indicating that more research is needed in this area. From current research, we could identify that there are multiple subtypes of macrophages, having diverse biological effects, and that the ratio between subtypes is altered during gestation and in aberrant pregnancy. The study of macrophages’ phenotypes and their functions in OD pregnancies might be beneficial to better understand the maternal-fetal tolerance system.

Abstract
The human endometrium undergoes sequential phases of shedding of the upper functionalis zone during menstruation, followed by regeneration of the functionalis zone from the remaining basalis zone cells, and secretory differentiation under the influence of the ovarian steroid hormones estradiol (E2) and progesterone (P4). This massive tissue regeneration after menstruation is believed to arise from endometrial stromal and epithelial stem cells residing in the basal layer of the endometrium. Although many endometrial pathologies are thought to be associated with defects in these stem cells, studies on their identification and regulation are limited, primarily due to lack of easily accessible animal models, as these processes are unique to primates. Here we describe a robust new method to study endometrial regeneration and differentiation processes using human endometrial tissue slice cultures incorporating an air-liquid interface into a 3D matrix scaffold of type I collagen gel, allowing sustained tissue viability over three weeks. The 3D collagen gel-embedded endometrial tissue slices in a double-dish culture system responded to ovarian steroid hormones, mimicking the endometrial changes that occur in vivo during the menstrual cycle. These changes included the E2-induced upregulation of Ki-67, estrogen receptor (ER), and progesterone receptor (PR) in all endometrial compartments and were markedly suppressed by both P4 and E2 plus P4 treatments. There were also distinct changes in endometrial morphology after E2 and P4 treatments, including subnuclear vacuolation and luminal secretions in glands as well as decidualization of stromal cells, typical characteristics of a progestational endometrium in vivo. This long-term slice culture method provides a unique in vivo-like microenvironment for the study of human endometrial functions and remodeling during early pregnancy and experiments on stem cell populations involved in endometrial regeneration and remodeling. Furthermore, this model has the potential to enable studies on several endometrial diseases, including endometrial cancers and pregnancy complications associated with defects in endometrial remodeling.

Abstract
Objectives This study aimed to identify the possible effects of Myc and 8q24 polymorphisms on bleeding complications in patients who maintained international normalized ratio (INR) of 2.0-3.0 with warfarin therapy after cardiac valve replacement. Methods Twenty-five single nucleotide polymorphisms were analyzed, including VKORC1, CYP2C9, Myc, and 8q24. Univariate and multivariate analyses were conducted to evaluate the associations between genetic polymorphisms and bleeding complications. Attributable risk and the number needed to genotype (NNG) were also calculated to evaluate the potential clinical value of genotyping. Results We included 142 patients, among whom 21 experienced bleeding complications. Multivariate models showed that patients carrying the CC genotype of rs6983561 and the A allele of rs13281615 at 8q24 had 27.6- and 10.0-fold higher bleeding complications, compared with patients with the A allele and the GG genotype, respectively. For rs6983561, the attributable risk and NNG were 96.4% and 36.8, respectively, whereas, for rs13281615, the attributable risk and NNG were 90.0% and 8.3, respectively. Atrial fibrillation was associated with a 5.5-fold increased risk of bleeding complications. The AUROC value was 0.761 (95% CI 0.659-0.863, p<0.001), and the Hosmer–Lemeshow test showed that the fitness of the multivariate analysis model was satisfactory (χ2=0.846; 3 degrees of freedom; p=0.838). Conclusions Bleeding complications during warfarin therapy were associated with 8q24 polymorphisms and atrial fibrillation in patients with mechanical heart valves.

Abstract
OBJECTIVES This study aimed to determine the association between hepatocyte nuclear factor 4 alpha (HNF4A) polymorphisms and bleeding complications in patients on warfarin with international normalized ratios between 2.0 and 3.0 after cardiac valve replacement. METHODS Nineteen single nucleotide polymorphisms of HNF4A in addition to VKORC1 rs9934438 and CYP2C9 rs1057910 were analyzed. Univariate and multivariate analyses were conducted to evaluate associations between genetic polymorphisms and bleeding risk. Attributable risk and number needed to genotype (NNG) were calculated to assess clinical value of genotyping. RESULTS Of 142 patients, 21 experienced bleeding complications. Multivariate logistic regression analysis was conducted using factors with P <0.1 in univariate analysis. Multivariate analysis showed that patients with the CC genotype of rs6130615 had an 8.4-fold increased risk of bleeding, compared with patients with the T allele. Attributable risk and NNG were 88.1% and 32.2, respectively. Patients with the TT genotype of rs3212191 had a 3.8-fold increased risk of bleeding, compared with C allele carriers, while patients with variant-type homozygotes for rs1884613 showed an 8.7-fold higher bleeding complication than C allele carriers. The attributable risk/NNG of rs3212191 and rs1884613 were 73.4%/17.6 and 88.5%/22.8, respectively. Among comorbidities, atrial fibrillation was the only significant risk factor for bleeding complications. CONCLUSION Bleeding complications during warfarin therapy in patients with mechanical heart valves were associated with HNF4A polymorphisms and atrial fibrillation.

Abstract
Purpose: GATA4 and GATA6 are known to have potential roles in vascular regulation by affecting vascular smooth muscle cell differentiation and atrial natriuretic peptide levels. The aim of this retrospective study was to investigate the associations between GATA4 and GATA6 polymorphisms and bleeding complication risk at a therapeutic international normalized ratio (INR) in patients with mechanical heart valves. Patients and methods: Study patients were included from the Ewha-Severance Treatment (EAST) Group of Warfarin. It consisted of 229 patients who received warfarin therapy after undergoing mechanical heart valve replacement and maintained a stable INR (INR of 2.0–3.0 for at least three consecutive times). Twenty single-nucleotide polymorphisms including VKORC1, CYP2C9, GATA4, and GATA6 were analyzed. Multivariate logistic regression analysis was employed to investigate the independent risk factors for bleeding complications. To evaluate the potential clinical value of genotyping for preventing bleeding complications in patients with high-risk genotype, the number needed to genotype (NNG) was also calculated. Results: One hundred forty-two patients were included in this study, 21 of whom had bleeding complications. After adjusting covariates, TT genotype carriers of rs13273672 in GATA4 and CC genotype carriers of rs10454095 in GATA6 showed 5.0- (95% CI, 1.6–15.7) and 3.1-fold (95% CI, 1.1–8.7) higher bleeding complications than carriers of C allele and T allele, respectively. NNG for preventing one patient from experiencing bleeding complications in patients with TT genotype of rs13273672 and CC genotype of rs10454095 was 22.2 and 17.5, respectively. Patients with both TT genotype in rs13273672 and CC genotype in rs10454095 showed 8.7-fold (95% CI, 1.7–46.1) higher bleeding complications than those with other genotypes. NNG in patients having both TT genotype in rs13273672 and CC genotype in rs10454095 was calculated to be 40.0. Conclusions: This study showed that GATA4 and GATA6 gene polymorphisms could affect bleeding complications during warfarin treatment in patients with mechanical heart valves.

Abstract
BACKGROUND Decidualization of the human endometrium, which involves a dramatic morphological and functional differentiation of human endometrial stromal cells (ESCs), is essential for the establishment of a successful pregnancy. Decidualization results from a complex interplay of transcription factors, morphogens, cytokines, cell cycle regulators, and signaling pathways. METHODS Based on a literature review, the regulation of, and the molecular mechanisms involved in, the decidualization of the endometrium are described. MAIN FINDINGS Progesterone, together with proteins that are regulated by progesterone and/or cyclic adenosine monophosphate, including homeobox A10, forkhead box O1, signal transducers and activators of transcription, and heart and neural crest derivatives expressed transcript 2, forms a critical network for ESC decidualization and is a prerequisite to successful implantation. Decidualized ESCs contribute to the microenvironment at the feto-maternal interface and its direct or indirect influence on extracellular matrix remodeling, regulation of the local immune response, anti-oxidative stress, and angiogenesis (vascular maturation). Impairment of this process is associated with a variety of pregnancy disorders, including infertility, recurrent miscarriages, and uteroplacental disorders. CONCLUSION A deeper understanding of the process of decidualization is expected to provide new insights into the fields of reproductive biology and reproductive medicine.

Abstract
AIM to investigate the molecular mechanisms and morphological substrate of reduced uterine leiomyoma in patients receiving the selective progesterone receptor modulator (SPRM) ulipristal acetate for 3 months, by estimating the immunohistochemical expression of the markers steroid receptor coactivator 1 (SRC-1), nuclear receptor corepressor 1 (NCoR-1), ER, PgR, Ki-67, p16, TGF-β, and VEGF in tumor tissue. SUBJECTS AND METHODS The investigation enrolled 75 women with uterine leiomyoma, menorrhagias, and anemia. Group 1 included 40 patients who were treated with ulipristal for 3 months, followed by laparoscopic myomectomy. Group 2 consisted of 35 patients who underwent surgery without previous preparation. The intra- and postoperative parameters and molecular and morphological changes in the myomatous nodules were comparatively analyzed in both groups. RESULTS After 3 months of therapy initiation, menorrhagia completely ceased, myomatous nodules decreased in size (p<0.05), hemoglobin levels were elevated (p<0.01), and total intraoperative blood loss and operative time decreased in all the patients in Group 1. The morphological substrate of partial leiomyoma reduction was leiomyocyte apoptosis and dystrophy, tumor stroma sclerosis and hyalinosis with diminished Ki-67 expression and elevated p16 in the smooth muscle cells, trophic nodular tissue disorders exhibited by vascular wall sclerosis and lower VEGF and TGF-β expression, and leiomyocyte hormonal reception dysregulation that made itself evident through the reduced expression of SRC-1 with the unchanged expression of PR and ER and the maintained level of NCoR-1. CONCLUSION The molecular mechanisms of tumor reduction involved the reduced Ki-67 expression and elevated p16, lower VEGF and TGF-β, diminished SRC-1 expression with the maintained level of PR, ER, and NCoR-1. Overall, this is suggestive of enhanced apoptosis and reduced leiomyoma proliferation and angiogenesis induced by SPRM and indicative of the expediency of using ulipristal acetate as a preoperative agent for organ-sparing surgery in reproductive-aged patients with uterine myoma, menorrhagias, and anemia.

Abstract
Heavy menstrual bleeding (HMB) is a common gynecological problem that has a significant impact on a woman’s quality of life and the activities of daily living. Due to the difficulty in accurately describing menstrual bleeding abnormalities using older terminology, the PALM-COEIN classification system of the Federation Internationale de Gynecologie et d’Obstetrique was proposed to describe and identify the etiology of abnormal endometrial bleeding. As there is no single pathway that is associated with HMB, there are several therapeutic interventions involving different molecular pathways to reduce HMB. This article will highlight the current evidence as it relates to the etiology of HMB as well as medical modalities of treatment.

Abstract
Objective Intrinsic inflammatory characteristics play a pivotal role in stem cell recruitment and homing through migration where the subsequent change in niche has been shown to alter these characteristics. The bone marrow mesenchymal stem cells (bmMSCs) have been demonstrated to migrate to the endometrium contributing to the stem cell reservoir and regeneration of endometrial tissue. Thus, the aim of the present study was to compare the inflammation-driven migration and cytokine secretion profile of human bmMSCs to endometrial mesenchymal stem cells (eMSCs) and endometrial fibroblasts (eSFs). Materials and methods The bmMSCs were isolated from bone marrow aspirates through culturing, whereas eMSCs and eSFs were FACS-isolated. All cell types were tested for their surface marker, proliferation profiles and migration properties towards serum and inflammatory attractants. The cytokine/chemokine secretion profile of 35 targets was analysed in each cell type at basal level along with lipopolysaccharide (LPS)-induced state. Results Both stem cell types, bmMSCs and eMSCs, presented with similar stem cell surface marker profiles as well as possessed high proliferation and migration potential compared to eSFs. In multiplex assays, the secretion of 16 cytokine targets was detected and LPS stimulation expanded the cytokine secretion pattern by triggering the secretion of several targets. The bmMSCs exhibited higher cytokine secretion of vascular endothelial growth factor (VEGF)-A, stromal cell-derived factor-1 alpha (SDF)-1α, interleukin-1 receptor antagonist (IL-1RA), IL-6, interferon-gamma inducible protein (IP)-10, monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)1α and RANTES compared to eMSCs and/or eSFs after stimulation with LPS. The basal IL-8 secretion was higher in both endometrial cell types compared to bmMSCs. Conclusion Our results highlight that similar to bmMSCs, the eMSCs possess high migration activity while the differentiation process towards stromal fibroblasts seemed to result in loss of stem cell surface markers, minimal migration activity and a subtler cytokine profile likely contributing to normal endometrial function.

Abstract
The objective of the study is to assess NOS3 and ESR1 gene polymorphism in adolescent girls born with low birth weight (LBW) and suffered by anomalous uterine bleeding (AUB). A total 95 adolescent girls were studied including 32 born with LBW and AUB; 36 girls with normal birth weight and AUB; and 27 healthy girls. Single allele gene polymorphism NOS3 786T > C, 894G > T, ESR1 351A > G and 397T > C was studied. The existence of polymorphous allele С gene NOS3 786Т > С (for homozygote OR = 2.03; 95% CI: 1.12-3.68; p = 0.04; for heterozygote OR = 1.68; 95% CI: 1.09-2.60; p = 0.046) and genotype Pvull-CC ESR1 (OR = 4.58; 95% CI: 0.97-21.68; p = 0.04) was detected in LBW girls with AUB. It was suggested that intrauterine programming of endothelial dysfunction syndrome could play a significant role in the development of AUB in adolescent girls born with LBW.

Abstract
Irregular uterine bleeding is a major side effect of long-acting progestogen-only contraceptives in women, and is the primary reason women discontinue their use. In this study, a mouse model of endometrial breakdown was established using a subcutaneous progesterone implant to understand how irregular bleeding begins. Although progestogens sustained decidualization, endometrial breakdown was still observed in this model. We, therefore, hypothesized that endometrial breakdown might involve functional progesterone withdrawal. Using co-immunoprecipitation assays, we observed the constitutive activation of nuclear factor kappa-b (NF-κB) p65 and its interaction with the progesterone receptor (PGR); moreover, transcriptional activity of the PGR was also repressed by NF-κB activity in primary mouse and human decidual stromal cells that mimic progesterone maintenance. Yet the ratio of PGR-B to PGR-A was not increased in the mouse model. In vivo comparison of endometrial breakdown induced by progesterone withdrawal to that seen during sustained progesterone exposure, in the presence of NF-κB inhibitors, revealed that NF-κB-mediated functional progesterone withdrawal is involved in endometrial breakdown in this implant model. These data prompt further studies to determine the homology of this functional progesterone withdrawal mechanism in human endometrium. Mol. Reprod.

Abstract
The prevalence of asthma is about 9,7 % in women and 5,5 % in men. Asthma can deteriorate during the perimenstrual period, a phenomenon known as perimenstrual asthma (PMA), which represents a unique, highly symptomatic asthma phenotype. It is distinguished from traditional allergic asthma by aspirin sensitivity, less atopy, and lower lung capacity. PMA incidence is reported to vary between 19 and 40 % of asthmatic women. The presence of PMA has been related to increases in asthma-related emergency department visits, hospitalizations and emergency treatment including intubations. It is hypothesized that hormonal status may influence asthma in women, focusing on the role of sex hormones, and specifically on the impact of estrogens' fluctuations at ovulation and before periods. This paper will focus on the pathophysiology of hormone triggered cycle related inflammatory/allergic events and their relation with asthma. We reviewed the scientific literature on Pubmed database for studies on PMA. Key word were PMA, mastcells, estrogens, inflammation, oral contraception, hormonal replacement therapy (HRT), and hormone free interval (HFI). Special attention will be devoted to the possibility of reducing the perimenstrual worsening of asthma and associated symptoms by reducing estrogens fluctuations, with appropriate hormonal contraception and reduced HFI. This novel therapeutical approach will be finally discussed.

Abstract
Tissue from endometrial diagnostic curettage material may show small clumps of stromal cells, which are pushed together (stromal collapse) and present a picture of glandular and stromal breakdown. This can be misinterpreted as small cell structured carcinoma, possibly of neuroendocrine or basal cell origin. Immunohistochemical investigations (e.g. estrogen receptor, epithelial and neuroendocrine markers and proliferation markers) are helpful in identifying the correct differential diagnosis.

Abstract
Use of long-acting progestin only contraceptives (LAPCs) offers a discrete and highly effective family planning method. Abnormal uterine bleeding (AUB) is the major side effect of, and cause for, discontinuation of LAPCs. The endometria of LAPC-treated women display abnormally enlarged, fragile blood vessels, decreased endometrial blood flow and oxidative stress. To understanding to mechanisms underlying AUB, we propose to identify LAPC-modulated unique gene cluster(s) in human endometrial stromal cells (HESCs). Protein and RNA isolated from cultured HESCs treated 7 days with estradiol (E2) or E2+ medroxyprogesterone acetate (MPA) or E2+ etonogestrel (ETO) or E2+ progesterone (P4) were analyzed by quantitative Real-time (q)-PCR and immunoblotting. HSCORES were determined for immunostained-paired endometria of pre-and 3 months post-Depot MPA (DMPA) treated women and ovariectomized guinea pigs (GPs) treated with placebo or E2 or MPA or E2+MPA for 21 days. In HESCs, whole genome analysis identified a 67 gene group regulated by all three progestins, whereas a 235 gene group was regulated by E2+ETO and E2+MPA, but not E2+P4. Ingenuity pathway analysis identified glucocorticoid receptor (GR) activation as one of upstream regulators of the 235 MPA and ETO-specific genes. Among these, microarray results demonstrated significant enhancement of FKBP51, a repressor of PR/GR transcriptional activity, by both MPA and ETO. q-PCR and immunoblot analysis confirmed the microarray results. In endometria of post-DMPA versus pre-DMPA administered women, FKBP51 expression was significantly increased in endometrial stromal and glandular cells. In GPs, E2+MPA or MPA significantly increased FKBP51 immunoreactivity in endometrial stromal and glandular cells versus placebo- and E2-administered groups. MPA or ETO administration activates GR signaling and increases endometrial FKBP51 expression, which could be one of the mechanisms causing AUB by inhibiting PR and GR-mediated transcription. The resultant PR and/or GR-mediated functional withdrawal may contribute to associated endometrial inflammation, aberrant angiogenesis, and bleeding.

Abstract
OBJECTIVES The menstrual cycle is characterised by cyclical fluctuations in oestrogens, progesterone and androgens. Changes in hormone levels in the premenstrual phase with the decline in progesterone trigger a physiological reaction which culminates in menstruation. This process is accompanied in many women by various symptoms such as pelvic pain, headache, mood disorders and gastrointestinal discomfort. The aim of this article was to summarise the latest findings on the physiology and pathophysiology of menstruation and review the impact of shortening the hormone-free interval (HFI) on the health and wellbeing of women. RESULTS Menstruation can be viewed as an inflammatory event in which local and systemic effects produce symptoms in genital and extragenital regions of the body. The mast cells are the main mediator of this reaction. In women using hormonal contraceptives, menstrual bleeding is not biologically necessary and it may be advantageous to maintain more stable levels of oestrogens, progesterone and androgens throughout the cycle. New combined oral contraceptives (COCs) have been formulated with a progressively shorter HFI (24/4 and 26/2) than traditional 21/7 pills, with the rationale of reducing hormone withdrawal- associated symptoms. Several studies have shown the beneficial effects of these regimens, which reduce the inflammatory exposure of the female organism and thus have the capacity to increase the quality of life of women. A combination of estradiol valerate (E2V) and dienogest (DNG) is administered on the shortest 26/2 regimen. This regimen has a broad evidence base from randomised controlled trials that have examined the impact of E2V/DNG on symptoms and quality of life. CONCLUSIONS Shortening the HFI reduces the occurrence of bleeding-related inflammatory processes and subsequent physical and mental symptoms. The shortest interval with evidence of reproductive and sexual health benefits is provided by a 26/2 regimen.

Abstract
The Wujia Shenghua capsule (WSC) is derived from Sheng-Hua-Tang, a well-known traditional Chinese medicine compound prescription that has been widely applied during the postpartum period in Chinese communities for a number of years. The aim of the present study was to investigate the effect of WSC on uterine bleeding following medically-induced incomplete abortion in rats during early pregnancy. Incomplete abortions were induced in Wistar rats during early pregnancy using mifepristone combined with misoprostol. The effects of WSC treatment were investigated in terms of the duration and volume of uterine bleeding, the uterine index and shape, and various hemodynamic indexes. In addition, blood samples were collected to measure the levels of estradiol (E2), fibronectin (FN) and laminin (LM) via a radioimmunoassay or enzyme-linked immunosorbent assay, while the expression levels of FN, estrogen receptor (ER) and progesterone receptor (PR) in the uterine tissues were determined by immunohistochemistry. The in vivo results demonstrated that WSC treatment markedly shortened the duration and reduced the volume of uterine bleeding when compared with the model group. Furthermore, WSC treatment significantly elevated the E2 level in the serum and the expression of the ER and PR in the uterine tissues, while notably decreasing the FN and LM levels in the serum and uterine tissues. In addition, the hemodynamic indexes were shown to improve with WSC treatment. These results demonstrated that WSC exerted an inhibitory effect on the bleeding caused by medical abortion, possibly through modulating the E2, ER, PR, FN and LM levels.

Abstract
Molecular mechanisms responsible for abnormal endometrial vasculature in women receiving long-acting progestin-only contraceptives (LAPCs) are unknown. We hypothesize that LAPCs impair vascular smooth muscle cell (VSMC) and pericyte proliferation and migration producing thin-walled hyperdilated fragile microvessels prone to bleeding. Proliferating cell nuclear antigen (PCNA) and α-smooth muscle actin (αSMA) double-immunostaining assessed VSMC differentiation and proliferation in endometria from women before and after DepoProvera (Depo) treatment and from oophorectomized guinea pigs (OVX-GPs) treated with vehicle, estradiol (E2), medroxyprogesterone acetate (MPA), or E2+MPA. Whole-genome profiling, proliferation, and migration assays were performed on cultured VSMCs treated with MPA or etonogestrel (ETO). Endometrial vessels of Depo-administered women displayed reduced αSMA immunoreactivity and fewer PCNA (+) nuclei among αSMA (+) cells (P < 0.008). Microarray analysis of VSMCs identified several MPA- and ETO-altered transcripts regulated by STAT1 signaling (P < 2.22 × 10(-6)), including chemokine (C-C motif) ligand 2 (CCL2). Both MPA and ETO reduce VSMC proliferation and migration (P < 0.001). Recombinant CCL2 reversed this progestin-mediated inhibition, whereas a STAT1 inhibitor abolished the CCL2 effect. Similarly, the endometria of MPA treated OVX-GPs displayed decreased αSMA staining and fewer PCNA (+) nuclei in VSMC (P < 0.005). In conclusion, LAPCs promote abnormal endometrial vessel formation by inhibiting VSMC proliferation and migration.

Abstract
In addition to surgical methods of treating uterine fibroids, numerous non-invasive treatments have been developed. Many of these involve the use of hyperthermia, the heating of tissue by a variety of methods. These include the use of lasers, radiofrequency, microwave energy and high intensity focused ultrasound, guided by both ultrasound and magnetic resonance imaging. In this review we examine the technology behind these treatment modalities and review the current evidence for their use.

Abstract
Epidemiological studies indicate that progestin-containing contraceptives increase susceptibility to HIV, although the underlying mechanisms involving the upper female reproductive tract are undefined. To determine the effects of depot medroxyprogesterone acetate (DMPA) and the levonorgestrel intrauterine system (LNG-IUS) on gene expression and physiology of human endometrial and cervical transformation zone (TZ), microarray analyses were performed on whole tissue biopsies. In endometrium, activated pathways included leukocyte chemotaxis, attachment, and inflammation in DMPA and LNG-IUS users, and individual genes included pattern recognition receptors, complement components, and other immune mediators. In cervical TZ, progestin treatment altered expression of tissue remodeling and viability but not immune function genes. Together, these results indicate that progestins influence expression of immune-related genes in endometrium relevant to local recruitment of HIV target cells with potential to increase susceptibility and underscore the importance of the upper reproductive tract when assessing the safety of contraceptive products.

Mass spectrometry identification of potential mediators of progestin-only contraceptive-induced abnormal uterine bleeding in human endometrial stromal cells. Contraception 2014; 91:253-60. [PMID: 25529278 DOI: 10.1016/j.contraception.2014.11.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2014] [Revised: 11/06/2014] [Accepted: 11/08/2014] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Thrombin and hypoxia each target human endometrial stromal cells (HESCs) to mediate long-acting progestin-only contraceptive (LAPC)-induced abnormal uterine bleeding (AUB). Thus, the secretome resulting from treatment of primary cultures of HESCs with thrombin or hypoxia was screened by mass spectrometry (MS) to detect potential protein mediators that lead to AUB. STUDY DESIGN Cultured HESCs were primed with estradiol±medroxyprogesterone acetate (MPA) or etonogestrel (ETO), the respective progestins in MPA-injected and ETO-implanted LAPCs, and then treated by incubation with thrombin or under hypoxia. Collected conditioned medium supernatants were used for protein identification and quantitation of potential AUB mediators by liquid chromatography combined with tandem mass spectrometry analysis. Microarray analysis of parallel cultures and immunostaining of endometrial biopsies of LAPC users vs. nonusers corroborated MS results. RESULTS MS identified several proteins displaying changes in expression levels from either thrombin or hypoxia treatments that are integral to angiogenesis or extracellular matrix formation. Several MS-identified proteins were confirmed by mRNA microarray analysis. Overexpressed stanniocalcin-1 (STC-1) was observed in endometrium of LAPC users. Unlike controls, all LAPC users displayed endometrial tubal metaplasia (ETM). CONCLUSIONS MS analysis identified many proteins that can affect angiogenesis or vessel integrity, thereby contributing to AUB. Confirmation of STC-1 overexpression in LAPC users and microarray data supports the validity of the MS data and suggests STC-1 involvement in AUB. The discovery of ETM in LAPC users indicates that LAPC-related side effects extend beyond AUB. The results presented here demonstrate a complex biological response to LAPC use. IMPLICATIONS MS identified several HESC secreted proteins deregulated by thrombin and hypoxia that may mediate LAPC-induced AUB. The revelation of overexpressed STC-1 by combined in vivo and in vitro observations identifies a potential target for future studies to prevent or minimize LAPC-induced AUB.

Abstract
CONTEXT Despite the absence of progesterone receptor protein in human endometrial endothelial cells (HEECs), endometria of women receiving long-acting progestin-only contraceptives (LAPCs) display reduced uterine blood flow, elevated reactive oxygen species generation, increased angiogenesis, and irregularly distributed, enlarged, fragile microvessels resulting in abnormal uterine bleeding. OBJECTIVE We propose that paracrine factors from LAPC-treated human endometrial stromal cells (HESCs) impair HEEC functions by shifting the balance between HEEC viability and death in favor of the latter. DESIGN AND SETTING Proliferation, apoptosis, and transcriptome analyses were performed in HEECs treated with conditioned medium supernatant (CMS) derived from HESCs treated with estradiol (E2) ± medroxyprogesterone acetate or etonogestrel under normoxia or hypoxia. Mass spectrometry interrogated the CMS secretome while immunostaining for neuronal pentraxin-1 (NPTX1), cleaved caspase-3, and cytochrome c was performed in cultured HEECs and paired endometria from women using LAPCs. MAIN OUTCOME HEEC apoptosis and its underlying mechanism. RESULTS HESC CMS from E2 + medroxyprogesterone acetate or E2 + etonogestrel incubations under hypoxia induced HEEC apoptosis (P < .05), whereas mass spectrometry of the CMS revealed increased NPTX1 secretion (P < .05). Endothelial cleaved caspase-3 and stromal NPTX1 immunoreactivity were significantly higher in LAPC-treated endometria (P < .001). Transcriptomics revealed AKT signaling inhibition and mitochondrial dysfunction in HEECs incubated with HESC CMS. In vitro analyses proved that CMS decreased HEEC AKT phosphorylation (P < .05) and that recombinant NPTX1 (P < .05) or NPTX1 + H2O2 (P < .001) increase HEEC apoptosis and cytosolic cytochrome c levels. CONCLUSIONS LAPC-enhanced NPTX1 secretion and reactive oxygen species generation in HESCs impair HEEC survival resulting in a loss in vascular integrity, demonstrating a novel paracrine mechanism to explain LAPC-induced abnormal uterine bleeding.

Abstract
The physiological function of the female reproductive organs is hormonally controlled. In each cycle, the reproductive organs undergo tissue modifications that are accompanied by formation and destruction of blood vessels. Proper angiogenesis requires an accurate balance between stimulatory and inhibitory signals, provided by pro- and anti-angiogenic factors. As with many other tissues, vascular endothelial growth factor (VEGF) appears to be one of the major pro-angiogenic factors in the female reproductive organs. Pigment epithelium-derived factor (PEDF) is a non-inhibitory member of the serine protease inhibitors (serpin) superfamily, possessing potent physiologic anti-angiogenic activity that negates VEGF activity. The role of PEDF in decreasing abnormal neovascularization by exerting its anti-angiogenic effect that inhibits pro-angiogenic factors, including VEGF, has been investigated mainly in the eye and in cancer. This review summarizes the function of PEDF in the reproductive system, showing its hormonal regulation and its anti-angiogenic activity. Furthermore, some pathologies of the female reproductive organs, including endometriosis, ovarian hyperstimulation syndrome, polycystic ovary syndrome, and others, are associated with a faulty angiogenic process. This review illuminates the role of PEDF in their pathogenesis and treatment. Collectively, we can conclude that although PEDF seems to play an essential role in the physiology and pathophysiology of the reproductive system, its full role and mechanism of action still need to be elucidated.

Abstract
Pigment epithelium-derived factor (PEDF) is highly expressed in the female reproductive system and is subjected to regulation by steroid hormones in the ovary. As the uterine endometrium exhibits morphological and functional changes in response to estrogen (E2) and progesterone (P4), we aimed at characterizing the expression of PEDF in this component of the female reproductive tract and further at exploring the hormonal regulation of its expression. We found that PEDF is expressed in human and mouse endometrium. We further showed that this expression is subjected to regulation by steroid hormones, both in vivo and in vitro, as follows: E2 decreased PEDF expression and P4 increased its levels. In human endometrial samples, PEDF levels were dynamically altered along the menstrual cycle; they were low at the proliferative and early secretory phases and significantly higher at the late secretory phase. The expression levels of PEDF were inversely correlated to that of vascular endothelial growth factor (VEGF). We also showed that PEDF receptor was expressed in the endometrium and that its stimulation reduced VEGF expression. Illustrating the pattern of PEDF expression during the menstrual cycle may contribute to our understanding of the endometrial complexity.

Abstract
Uterine fibroids (leiomyomata) are extremely common lesions that are associated with detrimental effects including infertility and abnormal uterine bleeding. Fibroids cause molecular changes at the level of endometrium. Abnormal regulation of growth factors and cytokines in fibroid cells may contribute to negative endometrial effects. Understanding of fibroid biology has greatly increased over the last decade. Although the current armamentarium of Food and Drug Administration-approved medical therapies is limited, there are medications approved for use in heavy menstrual bleeding that can be used for the medical management of fibroids. Emergence of the role of growth factors in pathophysiology of fibroids has led researchers to develop novel therapeutics. Despite advances in medical therapies, surgical management remains a mainstay of fibroid treatment. Destruction of fibroids by interventional radiological procedures provides other effective treatments. Further experimental studies and clinical trials are required to determine which therapies will provide the greatest benefits to patients with fibroids.

Abstract
OBJECTIVE To study the effect of estrogen on anovulatory dysfunctional uterine bleeding (ADUB). METHODS Primary endometrial epithelial cells of Hainan Lizu female was cultured and hydrolytic activity of gelatinase was determined by gelatin zymography analysis. Cellular mRNA and protein synthesis was blocked respectively to determine whether the increased expression of MMP-2/9 was induced by estrogen. The expression of VEGF was blocked by siRNA. After treatment with various factors, MMP-9, VEGF, total Erk and phosphorylated Erk expression in primary uterine epithelial cells was detected by Western blotting analysis. Cell MMP-2/9mRNA levels was measured by real-time RT-PCR. RESULTS The activity and expression of MMP2/9 was increased in the endometrium of patients with ADUB. Estrogen could up-regulate the expression of VEGF and activate Erk 1/2-Elk1 signal path. After interference by siRNA, ERK1/2 pathway was blocked in cells, and the expression of MMP-2/9 was down-regulated. ERK1/2 specific blocker U0126 blocked ERK phosphorylation, and it could down-regulate the expression of MMP-2/9. CONCLUSIONS The results showed that the estrogen can increase the expression of VEGF, and thus activate ERK1/2 pathway to induce MMP-2/9 expression.

Abstract
Menstruation is a complex process dependent on premenstrual release of inflammatory mediators and proteolytic enzymes from endometrial cells. Endometrial leukocytes are traditionally considered to be the major source of the inflammatory factors. However, evidence is emerging to suggest a role for decidualized endometrial stromal cells in the premenstrual inflammatory cascade. We sought to determine if withdrawal of hormone support (estrogen and progesterone) from decidualized endometrial stromal cells, in a model mimicking the precise timing leading to menstruation, activated inflammatory signaling pathways and downstream release of inflammatory mediators. Human endometrial stromal cells decidualized gradually over 12 days of estradiol and progestin treatment as evidenced by an increase in prolactin secretion. Withdrawal of hormone support from decidualized stromal cells resulted in a decrease in cytoplasmic IkappaB and a progressive increase in nuclear accumulation of NF-kappaB, as demonstrated by Western immunoblot and immunocytochemical analyses. Concomitant with nuclear translocation of NF-kappaB, hormone withdrawal led to production of a host of inflammatory mediators by the decidualized stromal cells, including IFN-alpha, IL-6, CCL11, GM-CSF, CCL2, IL1-RA, CXCL10, CXCL8, IL-12, IL-15, VEGF, and CCL5. Elevation of inflammatory mediators was not observed, however, upon hormone withdrawal in cells treated with the NF-kappaB inhibitor BAY 11-7085. Decidualized stromal cells are likely highly sensitive sensors of changing hormone levels. This provides a mechanism by which decidualized stromal cells may recruit inflammatory leukocytes into the premenstrual endometrium and contribute to the intense inflammation underlying this unique physiological process.

Abstract
The past few decades have seen major advances in multidisciplinary obstetric care and management of gynecological conditions in women with bleeding disorders. Awareness of the impact of bleeding disorders has improved among the obstetric and gynecological community. Undiagnosed bleeding disorders can be the underlying cause for a significant proportion of women with heavy menstrual bleeding. They may also be the cause or a contributory factor for other gynecological problems, such as dysmenorrhea, intermenstrual bleeding, and endometriosis. Hemostatic assessment should be considered in women referred for menstrual abnormalities if they have a positive bleeding history as quantified by bleeding assessment tools. The reproductive choices and options for prenatal diagnosis are also expanding for families with hemophilia with a drive toward achieving a non-invasive approach. Current non-invasive prenatal diagnostic techniques are limited to identification of fetal gender. Research is ongoing to overcome the specific diagnostic challenges of identifying hemophilia mutations, utilizing free fetal DNA circulating in maternal plasma. The management of obstetric hemorrhage has recently evolved to include a greater focus on the identification of and early treatment for coagulation disorders. Deficiencies in certain hemostatic variables are associated with progression to more severe bleeding; therefore, specific interventions have been proposed to target this. Evidence is still lacking to support such strategy, and future research is required to assess the efficacy and the safety of these hemostatic interventions in women with persistent PPH.

Abstract
Menstruation has many of the features of an inflammatory process. The complexity and sequence of inflammatory-type events leading to the final tissue breakdown and bleeding are slowly being unravelled. Progesterone has anti-inflammatory properties, and its rapidly declining levels (along with those of estrogen) in the late secretory phase of each non-conception cycle, initiates a sequence of interdependent events of an inflammatory nature involving local inter-cellular interactions within the endometrium. Intracellular responses to loss of progesterone (in decidualized stromal, vascular and epithelial cells) lead to decreased prostaglandin metabolism and loss of protection from reactive oxygen species (ROS). Increased ROS results in release of NFκB from suppression with activation of target gene transcription and increased synthesis of pro-inflammatory prostaglandins, cytokines, chemokines and matrix metalloproteinases (MMP). The resultant leukocyte recruitment, with changing phenotypes and activation, provide further degradative enzymes and MMP activators, which together with a hypoxic environment induced by prostaglandin actions, lead to the tissue breakdown and bleeding characteristic of menstruation. In parallel, at sites where shedding is complete, microenvironmentally-induced changes in phenotypes of neutrophils and macrophages from pro- to anti-inflammatory, in addition to induction of growth factors, contribute to the very rapid re-epithelialization and restoration of tissue integrity.

Abstract
Under normal physiological circumstances menstruation is a highly regulated, complex process that is under strict hormonal control. During normal menstruation, progesterone withdrawal initiates menstruation. The cessation of menstrual bleeding is achieved by endometrial haemostasis via platelet aggregation, fibrin deposition and thrombus formation. Local endocrine, immunological and haemostatic factors interact at a molecular level to control endometrial haemostasis. Tissue factor and thrombin play a key role locally in the cessation of menstrual bleeding through instigation of the coagulation factors. On the other hand, fibrinolysis prevents clot organisation within the uterine cavity while plasminogen activator inhibitors (PAI) and thrombin-activatable fibrinolysis inhibitors control plasminogen activators and plasmin activity. Abnormalities of uterine bleeding can result from imbalance of the haemostatic factors. The most common abnormality of uterine bleeding is heavy menstrual bleeding (HMB). Modern research has shown that an undiagnosed bleeding disorder, in particular von Willebrand disease (VWD) and platelet function disorders, can be an underlying cause of HMB. This has led to a change in the approach to the management of HMB. While full haemostatic assessment is not required for all women presenting with HMB, menstrual score and bleeding score can help to discriminate women who are more likely to have a bleeding disorder and benefit from laboratory haemostatic evaluation. Haemostatic agents (tranexamic acid and DDAVP) enhance systemic and endometrial haemostasis and are effective in reducing menstrual blood loss in women with or without bleeding disorders. Further research is required to enhance our understanding of the complex interactions of haemostatic factors in general, and specifically within the endometrium. This will lead to the development of more targeted interventions for the management of abnormal uterine bleeding in the future.

Abstract
The term 'luteal phase deficiency' was first coined more than 60 years ago, and, since then, it has been suggested as a clinical entity per se and an aetiological factor for subfertility, implantation failure and recurrent miscarriage. Despite the existing recommendations for rational work-up in subfertility, luteal phase evaluation and progesterone therapy alone is still common in daily practice. This review comprises results from a Pubmed literature search with the terms 'luteal phase' and 'subfertility', focussing on clinical situations not primarily related to assisted reproduction techniques. Additional data from the experimental studies published in the past 10 years on follicular maturation, oocyte developmental competence and the ovulatory cascade are integrated into the clinical continuum of dysfunctional ovulation, menstrual cycle irregularity and impaired corpus luteum function. As reliable diagnostic tools for adequate luteal function are missing, the presence of clinical symptoms such as cycle irregularity or premenstrual spotting is indicative and should initiate early follicular phase diagnostic work-up. New evidence on the interdependence of oocyte and follicular maturation and resulting developmental competence of the embryo further support the use of ovarian stimulation as the first-line therapeutic option in different subsets of patients with subfertility including luteal phase deficiency.

Abstract
Micro RNAs (miRNAs) are small non-coding RNAs which regulate numerous cellular processes at the posttranscriptional and translational level. In endometriosis, expression of miRNAs is frequently dysregulated. miRNAs are predicted to modulate several relevant processes involved in the pathogenesis of endometriosis, including cell proliferation, apoptosis, cell migration and invasiveness, angiogenesis, and inflammation, as well as stem cell properties. miRNA expression has been studied by microarray profiling and quantitative real-time PCR, enabling the identification of specific miRNAs as potential novel diagnostic markers for endometriosis. The future application of locked-nucleic acid miRNA inhibitors, miRNA decoys, and synergistic approaches involving conventional therapeutics may open up promising new perspectives in endometriosis therapy.

Abstract
Pregnancy success is determined by a complex progress that includes trophoblast invasion and placentation. Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are metal-dependent endopeptidases capable of degrading extracellular matrix, and appear to play a critical role in trophoblast invasion. This article reviews in detail the role of MMPs, TIMPs, and their regulators in the mechanism of trophoblast invasion in early human pregnancy.

Abstract
Excessive menstrual bleeding reflects aberrant angiogenesis, generally due to submucosal myomas and endometrial polyps, although it is also frequently observed with long-term progestin-only contraception, impaired haemostasis and hormonal disorders. Surgery (hysterectomy, endometrial ablation) is used too frequently. Uterine artery embolisation is also an option for myomas. Medical treatments include combined oral contraception, progestins and levonorgestrel-releasing Intrauterine System. Gonadotropin-releasing hormone agonists provide significant improvements in bleeding for myomas, but also decrease estrogen secretion (e.g. hot flushes, decreased bone mass). Progestins, although used widely, remain poorly effective as they promote myoma cell growth. Recently, Selective Progesterone Receptor Modulators (SPRMs) have been shown to induce amenorrhea whilst maintaining endogenous estrogen secretion. Phase II studies have also demonstrated decreased fibroid size in SPRM-treated women. Although the mechanism of amenorrhea observed after SPRM treatment is still poorly understood, they may control uterine bleeding via a direct effect on endometrial blood vessels. Suppression of bleeding in women with uterine fibroids receiving SPRMs is associated with moderate reductions in uterine artery blood flow, without major changes in angiogenic factors and extracellular matrix composition; a clear difference to modifications observed with progestins. These data suggest major progress in the treatment of excessive menstrual bleeding.
