Abstract
Digestive system infiltrating endometriosis (DSIE) is an uncommon form of endometriosis in the digestive system. DSIE often occurs in the intestines (especially the sigmoid rectum), liver, gallbladder and pancreas. Clinically, DSIE presents with the same symptoms as endometriosis, including cyclic pain, bleeding and infertility, in addition to specific biliary/intestinal obstruction and gastrointestinal bleeding. Compared to general endometriosis, DSIE has unique biological behaviour and pathophysiological mechanisms. Most DSIEs are deep invasive endometrioses, characterized by metastasis to the lymph nodes and lymphatic vessels, angiogenesis, peripheral nerve recruitment, fibrosis and invasion of surrounding tissues. DSIE-related peripheral angiogenesis is divided into three patterns: angiogenesis, vasculogenesis and inosculation. These patterns are regulated by interactions between multiple hypoxia-hormone cytokines. The nerve growth factors regulate the extensive neurofibril recruitment in DSIE lesions, which accounts for severe symptoms of deep pain. They are also associated with fibrosis and the aggressiveness of DSIE. Cyclic changes in DSIE lesions, recurrent inflammation and oxidative stress promote repeated tissue injury and repair (ReTIAR) mechanisms in the lesions, accelerating fibril formation and cancer-related mutations. Similar to malignant tumours, DSIE can also exhibit aggressiveness derived from collective cell migration mediated by E-cadherin and N-cadherin. This often makes DSIE misdiagnosed as a malignant tumour of the digestive system in clinical practice. In addition to surgery, novel treatments are urgently required to effectively eradicate this lesion.

J Obstet Gynaecol Res 2023; 49:1366-1374.

Abstract
OBJECTIVES Although in vitro fertilization with embryo transfer is the most effective treatment for infertile patients with endometriosis, ovarian stimulation protocols are controversial. STUDY DESIGN We recruited 639 patients with endometriosis from January 2016 to June 2020; 111 and 528 patients were treated with the gonadotropin-releasing hormone (GnRH) antagonist and ultra-long GnRH agonist protocols, respectively. Potential baseline differences between the regimens were adjusted by propensity score matching. Clinical and laboratory data, including the cumulative clinical pregnancy rate (CCPR) and cumulative live birth rate (CLBR), were compared. RESULTS Ovulation induction required significantly longer use of gonadotropins in the GnRH agonist group. However, the GnRH agonist group had a lower starting dose of gonadotropin (all p < 0.05). Furthermore, significantly lower clinical pregnancy, implantation, and live birth rates were observed in the GnRH antagonist group receiving fresh assisted reproductive technology cycles (all p < 0.05); however, pregnancy outcomes using the subsequent freeze-thaw cycles for the same oocyte retrieval were not significantly different. CCPR and CLBR for the oocyte retrieval cycles of the antagonist and ultra-long agonist protocols were similar. The ultra-long agonist protocol resulted in more favorable implantation of fresh embryos and improved clinical outcomes of the fresh cycle. CONCLUSIONS This novel strategy could be appropriate for endometriosis patients who are temporarily unsuitable for fresh embryo transfer. The GnRH antagonist protocol can be combined with the whole embryo freezing strategy to achieve CCPR and CLBR similar to the ultra-long agonist regimen, thus simultaneously avoiding the long pre-treatment duration of GnRH agonists during the ultra-long agonist protocol.

Hum Reprod Update 2022; 28:838-857.

Abstract
BACKGROUND The positive effects of growth hormone (GH) on IVF are often attributed to improvements in oocyte and embryo quality. While emerging evidence emphasizes GH-induced improvements in the endometrium, these results are controversial. OBJECTIVE AND RATIONALE This meta-analysis aimed to evaluate whether GH administration improved endometrial function and reproductive outcomes during IVF cycles and to thus guide clinical practice. SEARCH METHODS A literature search in the Cochrane Central Register of Controlled Trials, PubMed and Embase was performed through to 30 November 2021, without language restrictions. Randomized controlled trials (RCTs) evaluating the effects of GH on IVF outcomes were included. Risk of bias and quality of evidence (QoE) were assessed according to the Cochrane Collaboration's tool and the Grading of Recommendations Assessment, Development and Evaluation system. Odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs) were assessed by random-effects models. OUTCOMES A total of 25 trials with 2424 women were included. Seventeen RCTs with poor responders (n = 1723) showed that GH administration significantly increased endometrial thickness (EMT) (MD = 0.38, 95% CI: 0.18-0.59; moderate QoE), which contributed to an improved live birth rate (OR = 1.67, 95% CI: 1.13-2.49; very low QoE) and clinical pregnancy rate (CPR) (OR = 1.97, 95% CI: 1.43-2.72; low QoE). Subgroup analyses showed a dose- and time-dependent relationship between GH cotreatment and IVF outcomes; the optimal recommendation for improving CPR was consistent with that for EMT, rather than for oocytes and embryos. Hence, GH might improve fertility via effects on the endometrium. Administration of GH daily from the follicular phase of previous cycle until the hCG trigger with < 5 IU/day led to a thicker endometrium and a greater chance of becoming pregnant, while 5-10 IU/day or administration from the luteal phase of the previous cycle until the hCG trigger resulted in higher oocyte and embryo quality. Poor responders might benefit from cotreatment with the GnRH agonist long protocol more than other stimulation protocols. Pooled data from four trials (n = 354) on women with a thin endometrium indicated that improved endometrial function might be critical for improving reproductive outcomes during GH treatment, as no improvements in embryo quality were found. GH administration not only increased EMT (MD = 1.48, 95% CI: 1.21-1.75; moderate QoE) but also promoted endometrial morphology (OR = 2.67, 95% CI: 1.36-5.23; low QoE) and perfusion (OR = 5.84, 95% CI: 1.30-26.17; low QoE), thereby improving the CPR (OR = 2.71, 95% CI: 1.69-4.34; P < 0.0001; low QoE). There was insufficient evidence to reach a conclusion regarding the effects of GH in normal responders (n = 80). Due to obvious improvements in the CPR, women with a thin endometrium might be the most appropriate population to benefit from GH administration. WIDER IMPLICATIONS Improving endometrial function might be another vital mechanism by which GH improves IVF outcomes. Optimal treatment should be offered to the target population according to their personal conditions and needs. The QoE was moderate to very low, due to limited sample sizes and methodological problems; thus, the results should be interpreted with caution. More rigorous RCTs with large sample sizes are needed to confirm the effects and determine optimal GH protocols.

Abstract
OBJECTIVE To investigate whether the depot gonadotropin-releasing hormone (GnRH) agonist protocol could improve in vitro fertilization (IVF) outcomes for young poor responders from POSEIDON group 3. METHODS This retrospective cohort study was carried out from June 2017 to June 2020. A total of 451 patients were assigned to three groups depending on the ovarian stimulation protocols. The outcome parameters of IVF were compared in each group. RESULTS Patients who received the depot GnRH agonist had significantly higher cumulative clinical pregnancy rates (50.88%, 32.02%, and 31.88%, respectively; P = 0.009 and P = 0.007) and cumulative live birth rate (48.25%, 26.97%, and 28.99%, respectively; P = 0.004 and P = 0.009) compared with mild ovarian stimulation protocol and GnRH antagonist protocol. They also had higher live birth rate per fresh embryo transfer cycle (47.78%, 32.35%, and 36.62%, respectively), but these differences were not statistically significant. Moreover, duration of stimulation, total dose of gonadotropins and endometrial thickness were significantly higher among women who received the depot GnRH agonist (P < 0.001). However, they had lower embryo transfer cancellation rate, and abnormal endometrium rate (P < 0.001). CONCLUSION The depot GnRH agonist protocol may improve cumulative clinical pregnancy rate and cumulative live birth rate for young women with poor ovarian response from POSEIDON group 3.

Abstract
The optimal protocol for endometrial preparation in patients with infertility remains unclear. Due to this, the current study retrospectively analyzed 1,589 patients with infertility and regular menstrual cycles to assess reproductive outcomes per embryo transferred and per embryo transfer (ET) cycle following the transfer of frozen-thawed embryos (FET) in a modified natural cycle (mNC) or hormone therapy cycle (HT) with or without gonadotropin-releasing hormone agonist (GnRHa)-induced pituitary suppression. The molecular mechanisms involved were also studied using tissues from endometrial biopsies. Patients who underwent FET were assigned to 5 groups as follows: Group A underwent a mNC (n=276); group B (n=338) received estradiol (E2) and progesterone (P4); group C received 1 cycle of GnRHa, E2 and P4 (n=323); group D received 2 cycles of GnRHa, E2 and P4 (n=329); and group E received 3 cycles of GnRHa, E2 and P4 (n=323). Tissues from endometrial biopsies of 91 patients performed on the day of ET were tested for endometrial receptivity marker mRNA expression and microRNA (miR)-223-3p mRNA. Furthermore, endometrial stromal cells (ESCs) were used for an in-depth study of the molecular mechanisms involved. Among the 5 groups of patients, implantation rates, clinical pregnancy rates and live birth rates were not significantly different. However, endometrial receptivity was enhanced in group E when compared with groups A-D, which was associated with endometrial leukemia inhibitory factor (LIF), osteopontin, vascular endothelial growth factor, integrin β3 and homeobox gene 10 and 11 mRNA upregulation, and miR-223-3p miRNA downregulation. Transfection of ESCs with an miR-223-3p mimic significantly reduced levels of LIF mRNA and protein. In addition, pre-treating ESCs with GnRHa upregulated mRNA and protein expression of the decidualization markers prolactin and insulin-like growth factor binding protein-1 in a time-dependent manner. In conclusion, these results indicated that HT with GnRHa may be a potential endometrial preparation protocol for FET.

GnRH agonist administration prior to embryo transfer in freeze-all cycles of patients with endometriosis or aberrant endometrial integrin expression. Reprod Biomed Online 2017; 35:145-151.

Abstract
Prolonged gonadotrophin-releasing hormone agonist (GnRHa) administration before IVF with fresh embryo transfer to patients with endometriosis or aberrant endometrial integrin expression (-integrin) improves outcomes but may suppress ovarian response and prevents elective cryopreservation of all embryos. This retrospective cohort pilot study evaluates freeze-all cycles with subsequent prolonged GnRHa before embryo transfer in these populations. Patients from 2010 to 2015 who met inclusion criteria and received a long-acting GnRHa every 28 days twice before FET were evaluated. A subset underwent comprehensive chromosomal screening (CCS) after trophectoderm biopsy. Three groups were identified: Group 1: + CCS, +endometriosis (20 patients, 20 transfers); Group 2: +CCS, -integrin (12 patients, 13 transfers); Group 3: no CCS, +endometriosis or -integrin (10 patients, 12 transfers); Group 4: all transfers after CCS for descriptive comparison only (n = 2809). Baseline characteristics were similar among Groups 1-3 except that the mean surgery to oocyte aspiration interval was longer for Group 1 than Group 3. Implantation and ongoing pregnancy rates were statistically similar among the three groups and compared favourably to Group 4. A non-significant trend towards improved outcomes was noted in Group 1. Prolonged GnRHa after freeze-all in these patients avoids excessive ovarian suppression and results in excellent outcomes.

Abstract
The assisted reproductive technologies, particularly in vitro fertilization (IVF), represent the most efficient and successful means of overcoming infertility associated with endometriosis. Although older studies suggest that IVF outcomes are compromised in endometriosis patients, more contemporary reports show no differences compared to controls. The exception may be evidence of poorer outcomes and diminished ovarian response in women with advanced disease, particularly those with significant ovarian involvement or prior ovarian surgery. Prolonged pre-IVF cycle suppressive medical therapy, particularly gonadotropin releasing hormone agonists, appears to improve success rates in a subset of endometriosis patients. However, as of yet, there is no diagnostic marker to specifically identify those who would most benefit from this approach. Pre-IVF cycle surgical resection of nonovarian disease has not been consistently shown to improve outcomes with the possible exception of resection of deeply invasive disease, although the data is limited. Precycle resection of ovarian endometriomas does not have benefit and should only be performed for gynecologic indications. Indeed, there is a large body of evidence to suggest that this procedure may have a deleterious impact on ovarian reserve and response. A dearth of appropriately designed trials makes development of definitive treatment paradigms challenging.

Abstract
STUDY QUESTION Are protein oxidative stress markers [thiols, advanced oxidation protein products (AOPP), protein carbonyls and nitrates/nitrites] in perioperative peritoneal fluid higher in women with histologically proven endometriosis when compared with endometriosis-free controls? SUMMARY ANSWER Protein oxidative stress markers are significantly increased in peritoneal fluids from women with deep infiltrating endometriosis with intestinal involvement when compared with endometriosis-free controls. WHAT IS KNOWN ALREADY Endometriosis is a common gynaecologic condition characterized by an important inflammatory process. Various source of evidence support the role of oxidative stress in the development of endometriosis. STUDY DESIGN, SIZE, DURATION We conducted a prospective laboratory study in a tertiary-care university hospital between January 2011 and December 2012, and included 235 non-pregnant women, younger than 42 year old, undergoing surgery for a benign gynaecological condition. PARTICIPANTS/MATERIALS, SETTING, METHODS After complete surgical exploration of the abdomino-pelvic cavity, 150 women with histologically proven endometriosis and 85 endometriosis-free controls women were enrolled. Women with endometriosis were staged according to a surgical classification in three different phenotypes of endometriosis: superficial peritoneal endometriosis (SUP), ovarian endometrioma (OMA) and deeply infiltrating endometriosis (DIE). Perioperative peritoneal fluids samples were obtained from all study participants. Thiols, AOPP, protein carbonyls and nitrates/nitrites were assayed in all peritoneal samples. MAIN RESULTS AND THE ROLE OF CHANCE Concentrations of peritoneal AOPP were significantly higher in endometriosis patients than in the control group (median, 128.9 µmol/l; range, 0.3-1180.1 versus median, 77.8 µmol/l; range, 0.8-616.1; P < 0.001). In a similar manner concentrations of peritoneal nitrates/nitrites were higher in endometriosis patients than in the control group (median, 24.8 µmol/l; range, 1.6-681.6 versus median, 18.5 µmol/l; range, 1.6-184.5; P < 0.05). According to the surgical classification, peritoneal fluids protein AOPP and nitrates/nitrites were significantly increased only in DIE samples when compared with controls (P < 0.001 and P < 0.05; respectively), whereas the others forms of endometriosis (SUP and OMA) showed non-statistically significant increases. We found positive correlations between peritoneal fluids AOPP concentrations, nitrites/nitrates levels and the total number of intestinal DIE lesions (r = 0.464; P < 0.001 and r = 0.366; P = 0.007; respectively). LIMITATIONS, REASONS FOR CAUTION Inclusion of only surgical patients may constitute a possible selection bias. In fact, our control group involved women who underwent surgery for benign gynaecological conditions. This specificity of our control group may lead to biases stemming from the fact that some of these conditions, such as fibroids, ovarian cysts or tubal infertility, might be associated with altered peritoneal proteins oxidative stress markers. WIDER IMPLICATIONS OF THE FINDINGS We demonstrate the existence of a significantly increased protein oxidative stress status in peritoneal fluid from women with endometriosis especially in cases of DIE with intestinal involvement. This study opens the way to future more mechanistics studies to determine the exact role of protein oxidative stress in the pathogenesis of endometriosis. Even if an association does not establish proof of cause and effect, these intrinsic biochemical characteristics of endometriosis may lead to the evaluation of therapeutic approaches targeting oxidative imbalance. STUDY FUNDING/COMPETING INTERESTS No funding was used for this study. The authors have no conflict of interest.

Abstract
OBJECTIVE To investigate whether abnormal expression of Musashi-1 occurs in eutopic and ectopic endometria from patients with adenomyosis and whether it is correlated with serum estradiol or progesterone levels. STUDY DESIGN Musashi-1 expression in ectopic and paired eutopic endometrium of patients with adenomyosis (adenomyosis group, 30 cases) and in normal endometrium (control group, 29 cases) was studied with immunohistochemistry, and serum estradiol and progesterone levels in these cases were measured with electrochemiluminescence immunoassay. RESULTS In all the normal endometrial tissues from control group and paired eutopic and ectopic endometrium of adenomyosis, epithelial and stromal Musashi-1 expression was observed throughout the menstrual cycle. Musashi-1 immunostaining was localized both in the nucleus and cytoplasm. The epithelial cells in normal endometrium showed a significantly higher staining index of Musashi-1 in the proliferative phase than in the secretory phase. The staining index of epithelial Musashi-1 in the ectopic endometrium was significantly higher than in the paired eutopic endometrium and normal endometrium throughout the menstrual cycle. In the secretory phase, the epithelial Musashi-1 immunoreactivity in eutopic endometrium and the stromal Musashi-1 immunoreactivity in ectopic endometrium were significantly higher than those in the normal endometrium. The Musashi-1 expression in the ectopic endometrium of adenomyosis was not correlated with the serum estradiol or progesterone levels. CONCLUSION Aberrant Musashi-1 expression in adenomyosis may be involved in the pathogenesis and pathophysiology of adenomyosis, but it does not correlate with changes in serum estradiol or progesterone levels.

Abstract
OBJECTIVE Endometriosis is characterized by repeated inflammatory changes and serious adhesions, inducing innate and adaptive immune responses within the abdominal cavity. To assess these immune responses, we evaluated the levels of expression of Toll-like receptors (TLR)-1, -2, -4, -5, and -9; nucleotide-binding oligomerization domains (NOD)-1 and -2; interleukins-1β, -6, -8, -10, and -12; interferon-γ; tumor necrosis factor-α; inducible nitric oxide synthase (iNOS) and endothelial NOS (eNOS); and immunoglobulins (Igs) in patients with endometriosis. METHODS The levels of TLRs, NODs, cytokines, and NOS mRNAs in peritoneal effusions were assessed by real time reverse transcription-polymerase chain reaction; and IgG, IgA and IgM concentrations were measured by enzyme-linked immunosorbent assays (ELISA) in 40 patients with and 40 without endometriosis. Findings from the two groups were compared. RESULTS We observed expression of all pattern recognition receptors (PRRs), cytokines, and NOS mRNAs and Igs in the effusion fluid of patients with and without endometriosis. The levels of TLR-2 and -9; NOD-1 and -2; iNOS and eNOS mRNAs and CA 125 were significantly higher in the endometriosis than in the non-endometriosis group (p<0.05 each). Moreover, PRR, cytokine, and NOS expression showed significant correlations (p<0.05). CONCLUSIONS PRRs, cytokines, and NOS, which act cooperatively in the innate immune response, are closely associated with endometriosis. Increased expression of TLR-2, TLR -9, NOD-1, NOD-2, and NOS mRNA in peritoneal fluid may be associated with endometriosis.

Abstract
Nitric oxide synthase (NOS) immunoreactivity is present in goldfish gonadotrophs. The present study investigated whether two native goldfish gonadotrophin-releasing hormones (GnRHs), salmon (s)GnRH and chicken (c)GnRH-II, use NOS/nitric oxide (NO) and soluble guanylate cyclase (sGC)/cyclic (c)GMP/protein kinase G (PKG) signalling to stimulate maturational gonadotrophin [teleost gonadotrophin-II, luteinising hormone (LH)] release. In cell column perifusion experiments with dispersed goldfish pituitary cells, the application of three NOS inhibitors (aminoguanidine hemisulphate, 1400W and 7-nitroindazole) and two NO scavengers [2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (PTIO) and rutin hydrate] reduced sGnRH-elicited, but not cGnRH-II-induced, LH increases. The NO donor sodium nitroprusside (SNP) increased NO production in goldfish pituitary cells in static incubation. SNP-stimulated LH release in column perifusion was attenuated by PTIO and the sGC inhibitor 1H-(1,2,4)oxadiazolo[4,3-a]quinoxalin-1-oneon (ODQ), and additive to responses elicited by cGnRH-II, but not sGnRH. ODQ and the PKG inhibitor KT5823 decreased sGnRH- and cGnRH-II-stimulated LH release. Similarly, the LH response to dibutyryl cGMP was reduced by KT5823. These results indicate that, although only sGnRH uses the NOS/NO pathway to stimulate LH release, both GnRHs utilise sGC/PKG to increase LH secretion.

Abstract
The clinical manifestations of severe endometriosis are variable and unpredictable in both presentation and course. There are also a proportion of women with severe endometriosis who remain asymptomatic. The treatment of severe endometriosis must be individualised, taking into account the impact of the disease and treatment on pain, fertility and quality of life. Surgery is usually required and multiple organs are sometimes involved. Therefore, if endometriosis is severe, referral to a center with the expertise to offer all available treatments in a multidisciplinary team, including advanced laparoscopic surgery and laparotomy, is strongly recommended. It is also important to involve the woman in all decisions, to be flexible in diagnostic and therapeutic thinking, to maintain a good relationship with the woman and to seek advice where appropriate.

Abstract
Chronic thymus involution associated with aging results in less efficient T-cell development and decreased emigration of naïve T cells to the periphery. Thymic decline in the aged is linked to increased morbidity and mortality in a wide range of clinical settings. Negative consequences of these effects on global health make it of paramount importance to understand the mechanisms driving thymic involution and homeostatic processes across the lifespan. There is growing evidence that thymus tissue is plastic and that the involution process might be therapeutically halted or reversed. We present here progress on the exploitation of thymosuppressive and thymostimulatory pathways using factors such as keratinocyte growth factor, interleukin 7 or sex steroid ablation for therapeutic thymus restoration and peripheral immune reconstitution in adults.

Abstract
Posttransplant immunodeficiency, specifically a lack of T cell reconstitution, is a major complication of allogeneic bone marrow transplantation. This immunosuppression results in an increase in morbidity and mortality from infections and very likely contributes to relapse. In this study, we demonstrate that sex steroid ablation using leuprolide acetate, a luteinizing hormone-releasing hormone agonist (LHRHa), increases the number of lymphoid and myeloid progenitor cells in the bone marrow and developing thymocytes in the thymus. Although few differences are observed in the peripheral myeloid compartments, the enhanced thymic reconstitution following LHRHa treatment and allogeneic bone marrow transplantation leads to enhanced peripheral T cell recovery, predominantly in the naive T cell compartment. This results in an increase in T cell function in vivo and in vitro. Graft-versus-host-disease is not exacerbated by LHRHa treatment and graft-versus-tumor activity is maintained. Because LHRHa allows for reversible (and temporary) sex steroid ablation, has a strong safety profile, and has been clinically approved for diseases such as prostate and breast cancer, this drug treatment represents a novel therapeutic approach to reversal of thymic atrophy and enhancement of immunity following immunosuppression.

Abstract
OBJECTIVE To compare the efficacy of the microdose flare-up and multiple-dose antagonist protocols for poor-responder patients in intracytoplasmic sperm injection-ET cycles. DESIGN A randomized, prospective study. SETTING Center for assisted reproductive technology in Turkey. PATIENT(S) Ninety patients with poor ovarian response in a minimum of two previous IVF cycles. INTERVENTION(S) All women were prospectively randomized into two groups by computer-assisted randomization. The patients in group 1 were stimulated according to the microdose flare-up protocol (n = 45), while the patients in group 2 were stimulated according to antagonist multiple-dose protocol (n = 45). MAIN OUTCOME MEASURE(S) The mean number of mature oocytes retrieved was the primary outcome measure, and fertilization rate, implantation rate per embryo, and clinical pregnancy rates were secondary outcome measures. RESULT(S) The mean age of the women, the mean duration of infertility, basal FSH level, and the number of previous IVF cycles were similar in both groups. The total gonadotropin dose used was significantly higher in group 2, while the number of oocytes retrieved was significantly greater in group 1. Although the fertilization and clinical pregnancy rates were nonsignificantly higher in group 1 compared with group 2, the implantation rate was significantly higher in the microdose flare-up group than in the multiple-dose antagonist group (22% vs. 11%). CONCLUSION(S) The microdose flare-up protocol seems to have a better outcome in poor-responder patients, with a significantly higher mean number of mature oocytes retrieved and higher implantation rate.

Abstract
Poor immune recovery is characteristic of bone marrow transplantation and leads to high levels of morbidity and mortality. The primary underlying cause is a compromised thymic function, resulting from age-induced atrophy and further compounded by the damaging effects of cytoablative conditioning regimes on thymic epithelial cells (TEC). Several strategies have been proposed to enhance T cell reconstitution. Some, such as the use of single biological agents, are currently being tested in clinical trials. However, a more rational approach to immune restoration will be to leverage the evolving repertoire of new technologies. Specifically, the combined targeting of TEC, thymocytes and peripheral T cells, together with the bone marrow niches, promises a more strategic clinical therapeutic platform.

Abstract
OBJECTIVE To evaluate the safety and efficacy of hysteroscopic septum resection of the complete septate uterus with cervical duplication in patients with recurrent spontaneous abortions or infertility. DESIGN Prospective consecutive clinical study. SETTING University hospital for obstetrics, gynecology, and reproductive medicine. SUBJECT(S) Twenty-five patients with a complete septate uterus, cervical duplication, and history of recurrent spontaneous abortions (13 cases) or infertility (12 cases) were included. INTERVENTION(S) Hysteroscopic septum resection and sparing the double cervix using a bougie served as a means of orientation and blockage of internal cervical os. MAIN OUTCOME MEASURE(S) Intraoperative and postoperative complications, and postoperative anatomic identification of the uterus. RESULT(S) No intraoperative and postoperative complications were encountered. Postoperatively, ultrasound revealed minor fundal septal remnants in 7 (31.8%) of 22 patients receiving the ultrasound detection, and no residual septum in the other 15 cases (68.2%). CONCLUSION(S) By using a bougie technique, hysteroscopic correction of complete septate uterus with cervical duplication and sparing the double cervix can be performed successfully.

Abstract
PURPOSE To determine if temporarily blocking sex steroids prior to stem cell transplantation can increase thymus function and thus enhance the rate of T cell regeneration. EXPERIMENTAL DESIGN This was a pilot study of luteinizing hormone-releasing hormone agonist (LHRH-A) goserelin given 3 weeks prior to allogeneic or autologous hemopoietic stem cell transplantation and administered up to 3 months posttransplantation. Patients (with or without LHRH-A administration) were assessed from 1 week to 12 months posttransplantation for multiple immunologic variables by flow cytometry (particularly naïve T cells), quantitative PCR to assess T-cell receptor excision circle levels (as a correlate of thymus function), CDR3 length analysis to determine the variability of the TCR repertoire, and in vitro assays to determine functional T cell responses. RESULTS LHRH-A administration prior to stem cell transplantation significantly increased neutrophil and lymphocyte numbers within the first month of posttransplantation. Most importantly, total and naïve CD4(+) T cell regeneration together with T-cell receptor excision circle production, T cell repertoire regeneration, and peripheral T cell function were also significantly enhanced at multiple time points posttransplant. In addition, an increase in disease-free survival (P = 0.04) was seen in the autologous setting. Although LHRH-A administration increased T cell responses in vitro, it did not exacerbate graft-versus-host disease in the allogeneic setting. CONCLUSIONS This study provides an important new approach to the improvement of immune reconstitution in patients undergoing hemopoietic stem cell transplantation and may have generic applications in many T cell-based disorders.

Abstract
OBJECTIVE To study the clinicopathologic characteristics and the treatment means of pregnant women with uterine adenomyoma. DESIGN Retrospective, consecutive, controlled study. SETTING University hospital for obstetrics and gynecology. PATIENT(S) Eighteen pregnant women with uterine adenomyoma. INTERVENTION(S) Data collection and statistical analysis. MAIN OUTCOME MEASURE(S) Eighteen pregnant women with uterine adenomyoma were diagnosed by excision of adenomyoma tissue during cesarean section and histopathology. The 18 subjects were retrospectively divided into treatment group (achieving this pregnancy by treatment; 10 cases) and control group (having no difficulty conceiving; 8 cases). The clinicopathologic characteristics and treatment means of the patients were analyzed retrospectively. RESULT(S) The mean volume of uterine adenomyoma in the treatment group was larger than that of the control group. The methods of treating women with uterine adenomyoma-associated infertility include GnRH agonist (GnRH-a: 6 cases), GnRH-a and IVF and embryo transfer (3 cases), and traditional Chinese medicines (1 case). CONCLUSION(S) Severe uterine adenomyoma correlate with infertility in women of childbearing age. GnRH-a is effective in treating women with uterine adenomyoma-associated infertility.

Abstract
Endometriosis, defined as the ectopic presence of endometrial glandular and stromal cells outside the uterine cavity, is a common benign gynecological disorder with an enigmatic pathogenesis. Many genes and gene products have been reported to be altered in endometriosis, yet some of them may not be major culprits but merely unwitting accomplices or even innocent bystanders. Therefore, the identification and apprehension of major culprits in the pathogenesis of endometriosis are crucial to the understanding of the pathogenesis and would help to develop better therapeutics for endometriosis. Although so far NF-kappaB only has left few traces of incriminating fingerprints, several lines of investigation suggest that NF-kappaB, a pivotal pro-inflammatory transcription factor, could promote and maintain endometriosis. Various inflammatory agents, growth factors, and oxidative stress activate NF-kappaB. NF-kappaB proteins themselves and proteins regulated by them have been linked to cellular transformation, proliferation, apoptosis, angiogenesis, and invasion. Interestingly, all existing and nearly all investigational medications for endometriosis appear to act through suppression of NF-kappaB activation. In endometriotic cells, NF-kappaB appears to be constitutively activated, and suppression of NF-kappaB activity by NF-kappaB inhibitors or proteasome inhibitors suppresses proliferation in vitro. Viewing NF-kappaB as a major culprit, an autoregulatory loop model can be postulated, which is consistent with existing data and, more importantly, can explain several puzzling phenomena that are otherwise difficult to interpret based on prevailing theories. This view has immediate and important implications for novel ways to treat endometriosis. Further research is warranted to precisely delineate the roles of NF-kappaB in the pathogenesis of endometriosis and to indict and convict its aiders and abettors.
