Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demonstrated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel antiangiogenic therapy for endometriosis. 展开更多

Introduction: Cutaneous endometriosis is an uncommon but well-known skin disorder that represents about 0.5% to 1% of all endometriosis. The objective of this case series is to report clinical presentation, diagnosis, and management of various forms of cutaneous endometriosis. Material and Methods: It was an observational, retrospective and descriptive review of cases presenting with cutaneous endometriosis among Cameroonian women managed at the gynaecological outpatient department of Yaounde Gynaeco-Obstetric and Pediatric Hospital. All the following parameters were analysed: age, parity, previous pelvic surgery, presenting symptoms and duration, associated symptoms, localizations, imaging, size of the lesion, other localization of endometriosis, management and histopathological results. Results: we reported 4 cases of cutaneous endometriosis, with 3 umbilical endometriosis and 1 abdominal scar endometriosis. Patient age ranged from 28 to 39 years with an average of 33 years. All patients described infertility (two primary and two secondary) and two had a history of abdominal surgery. All patients presented local cyclical signs such as pain, swelling, color change and bleeding. The duration of symptoms varied from 2 to 3 years and the size of lesions ranged from 2 to 3.5 cm for umbilical lesions and was 9 cm for abdominal scar endometriosis. In all cases, no imaging was required for the diagnosis, which was suspected on the basis of patient’s history and the cyclical nature of local signs, followed by wide surgical excision and confirmation on histopathology. Conclusion: Cutaneaous endometriosis is a rare benign condition. Umbilical endometriosis seems to be the main cutaneous localization and can be described as primary or secondary. Even if its diagnosis must be confirmed by histopathology, it should be considered in patient with cutaneous cyclic signs such as pain, swelling or bleeding with or without history of abdominal surgery. 展开更多

Objective:To provide high-quality clinical evidence of the efficacy of Tibetan medicine Honghua Ruyi(HHRY)pills for endometriosis-associated dysmenorrhea.Methods:This study constitutes a multicenter,randomized,double-blind,placebo-controlled trial encompassing a three-menstrual cycle intervention followed by a three-menstrual cycle follow-up period.A total of 164 eligible females with endometriosis-associated dysmenorrhea were randomly divided into HHRY pills and placebo groups in a 1:1 ratio.The primary outcome included dysmenorrhea symptoms assessed using Visual Analog Scale(VAS)scores and quality of life,whereas the secondary outcome measures included the maximum VAS for non-menstrual pelvic pain,duration of pain episodes(in days),frequency and quantity of the consumption of ibuprofen sustained-release capsules(or other non-steroidal anti-inflammatory drugs),and days off work/study for staff/student due to dysmenorrhea,ovarian cyst,and/or pelvic nodule size.The safety was monitored throughout the treatment period.All the analyses were based on the intention-to-treat principle.For continuous outcomes,simple or multiple linear regressions were used to estimate the differences between the HHRY pills and placebo groups,with categorical data expressed as the number and percentage of occurrences.Differences were compared using the chi-square test or Fisher's exact test.The predefined analysis was adjusted for concomitant treatment,a variable considered to be associated with outcomes but unaffected by treatment allocation.Estimates of treatment effects were reported with 95%confidence intervals.Two-tailed P values≤.05 were considered statistically significant.Conclusion:Positive results from this trial,upon completion would provide robust evidence for the efficacy and safety of HHRY pills in treating dysmenorrhea in patients with endometriosis. 展开更多

Endometriosis is an estrogen-dependent inflammatory disease,defined by the presence of functional endometrial tissue outside of the uterine cavity.This disease is one of the main gynecological diseases,affecting around 10%-15%women and girls of reproductive age,being a common gynecologic disorder.Although endometriosis is a benign disease,it shares several characteristics with invasive cancer.Studies support that it has been linked with an increased chance of developing endometrial ovarian cancer,representing an earlier stage of neoplastic processes.This is particularly true for women with clear cell carcinoma,low-grade serous carcinoma and endometrioid.However,the carcinogenic pathways between both pathologies remain poorly understood.Current studies suggest a connection between endometriosis and endometriosis-associated ovarian cancers(EAOCs)via pathways associated with oxidative stress,inflammation,and hyperestrogenism.This article aims to review current data on the molecular events linked to the development of EAOCs from endometriosis,specifically focusing on the complex relationship between the immune response to endometriosis and cancer,including the molecular mechanisms and their ramifications.Examining recent developments in immunotherapy and their potential to boost the effectiveness of future treatments. 展开更多

Objective:To explore the effect of Hupo powder(HP)on autophagy in menstrual blood-derived stem cells(MenSCs)with endometriosis(EMT).Methods:EMT MenSCs(E-MenSCs)and healthy MenSCs(H-MenSCs)were isolated from the menstrual blood of patients with EMT and healthy female participants,respectively.We identified their stem cells’characteristics via adipogenic and osteogenic differentiation.Twelve male SpragueeDawley rats received 0.9% NaCl and HP-dispensing granules by gastric irrigation to prepare blank serum and medicated serum,respectively.We used serum concentrations of 5%,10%,and 20%,each at administered times of 12,24,and 48 h to select the best condition.These cells were divided into three groups:blank serum of the control group,blank serum of the model group,and medicated serum of the HP group.H-MenSCs were used in the control group,while E-MenSCs were used in the model and HP groups.We analyzed cell viability using a cell counting kit-8 assay,observed cell morphology,evaluated the amounts of auto-phagosomes and autolysosomes by transmission electron microscopy,and detected the protein expression of autophagy markers(LC3-II and Beclin1)by Western blot.Results:E-MenSCs and H-MenSCs became long fusiform with a diffuse radial pattern,forming lipid droplets and calcium nodules after adipogenic and osteogenic differentiation.We then used the best conditiond 20% serum and 48 hdfor the subsequent experiments.In contrast to the model group,the HP group exhibited lower cell viability(=0.007),larger amounts of autophagosomes and autolysosomes(P<0.001 and P=0.001,respectively),and higher expression of LC3-II and Beclin1(P=0.021 and P=0.019,respectively).Conclusion:Hupo powder can promote autophagy in E-MenSCs,which might be one of the mechanisms underlying its therapeutic effects. 展开更多

Endometriosis is a clinical and recurrent condition characterized by the presence of functional endometrial tissue outside the uterine cavity and myometrium. It is estimated that 6% to 10% of women of reproductive age, 50% to 60% of adolescents and adults with pelvic pain, and up to 50% of women with infertility are pregnant from the condition. However, this proportion tends to be even greater due to the difficulty in diagnosing it: because it presents different symptoms, lack of information from health professionals, and a high-cost diagnostic test. Another aggravating factor is the average time from the onset of symptoms to the medical diagnosis, which even today ranges from five to ten years;this delay has consequences for disease progression, as it prevents early treatment, which is important for improving pain levels and physical and psychological well-being. Aware of these mishaps, it is therefore important to assess the difficulties faced by doctors in the diagnosis of endometriosis in the public health system, in Brazil, the Unified Health System (SUS). With this purpose, a cross sectional was carried out, developed in the virtual environment using traffic in Google forms, with the difficulties quantified in the Likert scale. Participating physicians pointed out a medium difficulty for patients with endometriosis to access the consultation (58%) and moderate difficulty (52%) to perform an ultrasound examination;also signaled great difficulty in performing magnetic resonance imaging (77%) and laparotomy (61%) in these patients. It is hoped that knowledge about the difficulties faced by physicians in the diagnosis of endometriosis in the SUS will give these physicians a voice and corroborate, even if minimally, so that there is more research that provokes the search for these difficulties, in order to improving the quality of life of these women. 展开更多

Introduction: Endometriosis is a chronic disease affecting approximately 10% of women. Our aim was to describe the epidemiological profile, clinical presentation and location of lesions in patients operated on for endometriosis. Methodology: We conducted an analytical cross-sectional study with retrospective data collection over a period of 05 years from 1 January 2017 to 31 March 2022. Our study population consisted of women who had undergone laparoscopy for endometriosis. Data analysis was performed using SPSS software version 23.0. Results: In total we included 159 patients who had undergone laparoscopy for endometriosis. The mean age was 32.9 ± 5.9 years, most of whom were nuligravida 61.6% (n = 99). Infertility was the most frequent reason for consultation, accounting for 72.3% (n = 115), followed by dysmenorrhoea in 60.8% (n = 96) of cases and chronic pelvic pain in 37.7% (n = 60). In addition, 46 (28.9%) patients complained of deep dyspareunia, 17 (10.7%) of dyschezia and nine (5.7%) of dysuria. Magnetic Resonance Imaging (MRI) was used in one patient. Diagnostic laparoscopy was performed directly in 77 (48.4%) patients. The lesions were multifocal, according to the #ENZIAN classification nomenclature. Tubal lesions were most frequently found 107 (67.3%) on the left, followed by compartment B (uterosacral ligaments, cardinal ligaments and lateral pelvic wall) 49.7% (n = 79), and endometriomas 40.9% (n = 65). Conclusion: Women operated on for endometriosis were of a more advanced age, and predominantly nulliparous. Infertility was the most frequent reason for consultation and tubal location most frequently encountered for superficial lesions and compartiment B for deep lesions according to #ENZIA. 展开更多

Background:Chinese herbal medicines have been proven to be effective in clinical treatment and disease prevention.Jinlingzi San is a herbal medicine used for the treatment of endometriosis.However,a comprehensive network pharmacology approach has not been used to understand the active ingredients and therapeutic mechanisms behind Jinlingzi San in the treatment of endometriosis.Methods:A network pharmacology approach and a molecular docking approach were used to predict the active ingredients and potential targets of Jinlingzi San in the treatment of endometriosis.Results:The integrated network pharmacology approach successfully identified 60 active ingredients and 540 key targets of action in Jinlingzi San dispersion.Among them,STAT3,TP53,MAPK3,RELA,MAPK1,JUN and other key genes were mainly regulated through pathways in cancer,lipid and atherosclerosis,AGE-RAGE signaling pathway in diabetic complications,pancreatic cancer,prostate cancer,PI3K-Akt signaling pathway,Th17 cell differentiation,and other signaling pathways in the cell body,receptor complexes,cytoplasm,nucleoplasm,and plasma membrane.Conclusion:Based on a systems network pharmacology approach,our work successfully predicts the active components and potential targets of Jinlingzi San for the treatment of endometriosis and helps to illustrate the mechanism of action at an integrative level.This demonstrates that Jinlingzi San for the treatment of endometriosis is regulated through a multi-component,multi-target,multi-system co-regulation.This study identifies key genes and pathways associated with endometriosis and pathogenesis from new insights,and also provides a viable approach to the chemical basis and pharmacological studies of Jinlingzi San. 展开更多

Deep infiltrating endometriosis is an often-painful disorder affecting women during their reproductive years that usually involves the structures of the pelvis and frequently the gastrointestinal tract.We present the case of a 37-year-old female patient with an endometrial growth on the sigmoid colon wall causing pain,diarrhea and the presence of blood in the feces.The histology of the removed specimen also revealed the involvement of the utero-vesical fold,the recto-vaginal septum and a pericolic lymph node,which are all quite uncommon findings.To identify the endometrial cells,we performed immunohistochemical staining for CD10and the estrogen and progesterone receptors. 展开更多

Bowel endometriosis affects between 3.8% and 37% of women with endometriosis.The evaluation of symptoms and clinical examination are inadequate for an accurate diagnosis of intestinal endometriosis.Transvaginal ultrasonography is the first line investigation in patients with suspected bowel endometriosis and allows accurate determination of the presence of the disease.Radiological techniques (such as magnetic resonance imaging and multidetector computerized tomography enteroclysis) are useful for estimating the extent of bowel endometriosis.Hormonal therapies (progestins,gonadotropin releasing hormone analogues and aromatase inhibitors) significantly improve pain and intestinal symptoms in patients with bowel stenosis less than 60% and who do not wish to conceive.However,hormonal therapies may not prevent the progression of bowel endometriosis and,therefore,patients receiving long-term treatment should be periodically monitored.Surgical excision of bowel endometriosis should be offered to symptomatic patients with bowel stenosis greater than 60%.Intestinal endometriotic nodules may be excised by nodulectomy or segmental resection.Both surgical procedures improve pain,intestinal symptoms and fertility.Nodulectomy may be associated with a lower rate of complications. 展开更多
