Rudimentary horn pregnancy: clinical analysis of 12 cases and literature review / 中华妇产科杂志

Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

Rol de la laparoscopia en el manejo del síndrome OHVIRA: reporte de un caso y su relación con la endometriosis / Role of laparoscopy in the management of OHVIRA syndrome: a case report and its relation to endometriosis

El síndrome de hemivagina obstruida y anomalía renal ipsilateral (OHVIRA) es producido por una alteración en el desarrollo de los conductos de Müller y Wolff en la vida fetal. El síndrome es poco frecuente, se reporta una prevalencia de 1/2.000 a 1/28.000 casos. La endometriosis se presenta en un 19% de los casos complicando esta patología. El tratamiento del síndrome OHVIRA consiste en resecar el tabique vaginal drenando el hematocolpos. Hasta el momento no existe un consenso en recomendar la realización de una laparoscopia diagnóstica. El objetivo de este estudio es reportar la eventual importancia de la laparoscopia diagnóstica/terapéutica como parte del manejo del síndrome OHVIRA.

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is caused by a defect in the development of Müllerian and Wolffian ducts at fetal life. The syndrome is uncommon, with a reported prevalence of 1/2,000 to 1/28,000 cases. Endometriosis is present in 19% of cases complicating this pathology. Treatment of OHVIRA syndrome consists in resecting the vaginal septum and draining the hematocolpos. Until now there isnt an agreement on recommending diagnostic laparoscopy as part of the treatment. The aim of this study is to report the importance of diagnostic/therapeutic laparoscopy in the management of OHVIRA syndrome.

Malformação arteriovenosa uterina: um relato de caso / Uterine arteriovenous malformation: a case report

O presente estudo tem como objetivo relatar o caso de uma paciente com malformação arteriovenosa uterina, efetivamente tratada com embolização seletiva e com fertilidade preservada. A malformação arteriovenosa uterina é uma alteração vascular rara até então pouco descrita na literatura. A paciente do sexo feminino apresentou quadro de sangramento uterino anormal, com início 30 dias após um abortamento, sem realização de curetagem, de uma gestação resultante de fertilização in vitro. Foram, então, realizados exames de imagem, que levaram ao diagnóstico de malformação arteriovenosa uterina. O tratamento de escolha foi a embolização arterial seletiva, com resolução do caso. Após sete meses, nova fertilização in vitro foi realizada, encontrando-se na 36a semana de gestação. São necessários mais estudos sobre essa malformação a fim de que sejam estabelecidos os métodos mais eficazes para o manejo de casos futuros, especialmente quando há desejo de gestar.

The present study aims to report the case of a patient with uterine arteriovenous malformation, effectively treated with selective embolization and with preserved fertility. Uterine arteriovenous malformation is a rare vascular disorder that has so far been rarely described in the literature. Female patient presented with abnormal uterine bleeding, starting 30 days after an abortion without subsequent curettage, of a pregnancy resulting from in vitro fertilization. Imaging tests were then performed that led to the diagnosis of uterine arteriovenous malformation. The treatment of choice was selective arterial embolization, with successful results. After seven months, a new in vitro fertilization was performed, being in the 36th week of pregnancy. Further studies on this pathology are needed in order to establish the most effective methods for the management of future cases, especially when there is a desire to become pregnant.

Malformaciones müllerianas: actualización y revisión a propósito de casos clínicos, 2022 / Müllerian malformations: update and review of clinical cases, 2022

Las malformaciones müllerianas (MM) son un grupo de anomalías estructurales originadas por fallas de desarrollo de los conductos paramesonéfricos o de Müller durante las primeras 16 semanas de gestación. Un oportuno diagnóstico y una correcta clasificación permiten ofrecer el mejor manejo y diferenciar aquellas pacientes que requieren tratamiento quirúrgico. Se realizó una revisión de la literatura sobre MM en las bases de datos Epistemonikos, SciELO, Cochrane y PubMed. Se rescataron todas las pacientes ingresadas con diagnóstico de MM. En el año 2021, la American Society of Reproductive Medicine publicó un consenso en el que se estandarizó la nomenclatura, se amplió el espectro y se simplificó la clasificación. La clínica es variada, e incluye pacientes asintomáticas cuyo diagnóstico es un hallazgo por imágenes. Los mejores estudios imagenológicos son la resonancia magnética (RM) y la ultrasonografía 3D, dejando la histeroscopia y la laparoscopia (método de referencia) como procedimiento diagnóstico-terapéutico. Se presentan casos clínicos desarrollados durante el primer trimestre de 2022. Recomendamos la utilización sistemática de la RM para el diagnóstico de anomalías complejas u obstructivas del aparato genital. El tratamiento de estas patologías debe ser realizado por ginecólogos endoscopistas expertos, e incluye tratamiento médico y quirúrgico, el cual debe ser enfocado en cada paciente dependiendo del tipo de MM y de los deseos de fertilidad.

Müllerian malformations (MM) are a group of structural anomalies caused by developmental failure of the paramesonephric or Müllerian ducts during the first 16 weeks of gestation. Timely diagnosis and classification allow us to offer the best management and to differentiate those patients who require surgical treatment. Literature review on MM in Epistemonikos, SciELO, Cochrane and PubMed databases. All patients admitted with a diagnosis of MM were rescued. In 2021, the American Society of Reproductive Medicine publishes a consensus where it standardizes the nomenclature, broadens the spectrum, and simplifies the classification. The clinical picture is varied and includes asymptomatic patients whose diagnosis is an imaging finding. The best imaging studies are magnetic resonance imaging (MRI) and 3D ultrasonography, leaving hysteroscopy and laparoscopy (gold standard) as diagnostic therapeutic. Clinical cases developed during the first trimester 2022 are presented. We recommend the routine use of MRI for the diagnosis of complex and/or obstructive anomalies of the genital tract. The treatment of these pathologies should be performed by expert endoscopic gynecologists and include medical and surgical treatment, which should be focused on each patient, depending on the type of MM and fertility desires.

Importância do diagnóstico por imagem em pacientes com sangramento uterino anormal / Importance of diagnostic imaging in patients with abnormal uterine bleeding

O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.

Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

Espectro do acretismo placentário: recomendações atualizadas da perspectiva do profissional de imagem pré-natal / Placenta accreta spectrum disorders: current recommendations from the perspective of antenatal imaging

O parto cesáreo (PC) é o procedimento cirúrgico mais comumente realizado nos Estados Unidos (mais de 1 milhão de cirurgias por ano) e um dos procedimentos mais realizados em todo o mundo.(1) Embora o PC seja um procedimento potencialmente salvador de vidas, quando corretamente indicado, sua frequência aumentou constantemente nas últimas décadas (atualmente 21,1% globalmente, variando de 5%, na África Subsaariana, a 42,8%, na América Latina e no Caribe). Além disso, estudos demonstram tendência continuada de aumento (projeção para 2030: 28,5% globalmente, variando de 7,1%, na África Subsaariana, a 63,4%, no leste da Ásia).(2) República Dominicana, Brasil, Chipre, Egito e Turquia são os líderes mundiais, com taxas de PC variando de 58,1% a 50,8%, respectivamente, o que aponta para uma tendência preocupante de medicalização do parto e indicação excessiva do PC.(2) Outros procedimentos cirúrgicos como dilatação, curetagem, miomectomia e histeroscopia cirúrgica são menos frequentes que o PC. Ainda assim, devido à tendência de maior idade materna, o número de gestantes previamente submetidas a esses procedimentos também tende a aumentar. Esses dados apontam para um número crescente de gestações em úteros manipulados cirurgicamente Gestantes com cicatrizes uterinas prévias correm risco de aumento da morbimortalidade. Complicações como placenta prévia, rotura uterina espontânea, deiscência uterina (com ou sem intrusão placentária), gestação em cicatriz de cesariana (GCC) e distúrbios do espectro do acretismo placentário (EAP) estão associadas a sangramento uterino potencialmente fatal, lesões extrauterinas e parto pré-termo

Mucinous Cystadenoma Arising in a Uterine Isthmocele: A Case Report / Cistadenoma mucinoso surgindo em istmocele uterina: relato de caso

Abstract Isthmocele is a discontinuation of the myometrium at the uterine scar site in a patient with a previous cesarian section (CS). The cause of isthmocele appears to be multifactorial. Poor surgical technique, low incision location, uterine retroflection, obesity, smoking, inadequate healing of scars, and maternal age are possible related factors. Most patients with this condition are asymptomatic. However, women can present with postmenstrual bleeding, pelvic pain, subfertility, dysmenorrhea, infertility, and scar abscess. Brazil has one of the world s highest cesarean section rates. One of the consequences of the rising rate of CS is the isthmocele, an emerging female health problem. Here we report a case of mucinous cystadenoma arising in a uterine isthmocele, a complication, as far as we could investigate, not yet described in the literature.

Resumo Istmocele é a descontinuidade do miométrio no local da cicatriz uterina em paciente com cesariana anterior. A causa da istmocele parece ser multifatorial. Má técnica cirúrgica, baixa localização da incisão, retroflexão uterina, obesidade, tabagismo, cicatrização inadequada de cicatrizes e idade materna são possíveis fatores relacionados. A maioria dos pacientes com esta condição é assintomática. No entanto, as mulheres podem apresentar sangramento pós-menstrual, dor pélvica, subfertilidade, dismenorreia, infertilidade e abscesso cicatricial. O Brasil tem uma das maiores taxas de cesariana do mundo. Uma das consequências da taxa crescente de cesarianas é a istmocele, um problema emergente de saúde feminina. Aqui relatamos um caso de cistoadenoma mucinoso originado em uma istmocele uterina, uma complicação ainda não descrita, até onde pudemos investigar.

Efficacy of Embolization in Acquired Uterine Vascular Malformations: An Experience in Tertiary Care Centre in India / Eficácia da embolização em malformações vasculares uterinas adquiridas: uma experiência em centro de atendimento terciário na Índia

Abstract Objective: To determine the efficacy of Uterine Artery Embolization in patients with bleeding acquired uterine arteriovenous malformations (AVMs). Methods: A prospective review of all patients who underwent Uterine Artery Embolization at our institution between July 2015 and April 2022 was performed. 225 patients were diagnosed with a uterine vascular malformation on doppler and corresponding MRI imaging. All patients underwent transcatheter embolization of the uterine arteries. Embolic agents in the 375 procedures included Histoacryl glue only (n = 326), polyvinyl alcohol (PVA) particles and Histoacryl glue (n = 29), PVA particles (n = 5), Gelfoam (n = 5), coils (n = 4), PVA particles and coils (n = 3), Histoacryl glue and Gelfoam (n = 2), and Histoacryl glue and coils (n = 1). Results: A total of 375 embolization procedures were performed in 225 patients. 90 patients required repeat embolization for recurrence of bleeding. The technical success rate of embolization was 100%. The clinical success rate was 92%: bleeding was controlled in 222 of 225 patients and three patients underwent a hysterectomy. 60 of the 225 patients had uneventful intrauterine pregnancies carried to term. The 210 patients who underwent successful embolization had no recurrence of bleeding at a median follow-up of 53 months (range, 5-122 months) after treatment. 15 patients were eventually lost to follow-up. One minor complication (0.4%) of non-flow-limiting dissection of the internal iliac artery occurred. Conclusion: Uterine Artery Embolization is a safe, effective, minimally invasive method to treat uterine AVMs with long-term efficacy, which can provide the preservation of fertility.

Immunofluorescence Analysis of Estrogen and Progesterone Receptors and Ki-67 Nuclear Protein in Canine Uteri Treated with Medroxyprogesterone Acetate During Anestrus / Análisis de Inmunofluorescencia de Receptores de Estrógeno y Progesterona y Proteína Nuclear Ki-67 en Úteros Caninos Tratados con Acetato de Medroxiprogesterona Durante el Anestr

SUMMARY: Estradiol and progesterone receptors play an essential role in the changes occurring in the uterus during the estrus cycle in dogs (Canis lupus familiaris). In order to investigate the potential effect of progestational agent medroxyprogesterone acetate (MPA) when is used during anestrus on the expression of estradiol receptors [ER], progesterone receptors [PR] and nuclear protein Ki67, we evaluated uterine tissue immunohistochemically. Uteri were grouped as nulliparous (control, n=11), multiparous (n=11) and treated with MPA (n=11; nulliparous with two treatments; 5mg/kg; i.m.). The amount and location of PR, ER and Ki67 were studied on the epithelial surface, apical and basal regions of the endometrium and myometrium using immunohistochemical techniques with a spectral confocal microscope and analyzed by ANOVA. Differences in ER were observed between the multiparous and MPA-treated groups in the apical region of the endometrium (p=0.0022). Differences in cell proliferation were detected between the nulliparous and multiparous groups (p=0.0037) and nulliparous and MPA-treated groups (p=0.0003) in the basal region of the endometrium. In conclusion, two doses of MPA (5mg/kg; i.m.) do not have a significant effect on the expression of ER and PR; however, they inhibit cell proliferation in the basal region of the endometrium, which includes the stroma, subepithelial cell layer, compact layer, and spongy layer. The clinical and long-term effect of this treatment should be evaluated in subsequent studies.

Los receptores de estradiol y progesterona juegan un rol fundamental en los cambios que se producen en el útero durante el ciclo estral de las perras (Canis lupus familiaris). El objetivo de este estudio fue evaluar las expresiones de ER-a y PR en el útero y la proliferación de células endometriales detectando la expresión nuclear de la proteína Ki67 en perras expuestas a la progestina sintética MPA y compararlas con perras nulíparas y multíparas expuestas a progesterona luteal. Úteros fueron agrupados como nulíparas (control, n=11), multíparas (n=11) y tratadas con MPA (n=11; nulíparas con dos tratamientos; 5 mg/kg; i.m.). La expresión de PR, ER-a y Ki67 fue evaluada en la regiones apicales y basales del endometrio y miometrio con un microscopio confocal espectral. Se observó diferencias en ER-a entre los grupos multíparas y tratados con MPA en la región apical del endometrio (p=0,0022). Se detectaron diferencias en la proliferación celular entre los grupos de nulíparas y multíparas (p=0,0037) y los grupos de nulíparas y tratados con MPA (p=0,0003) en la región basal del endometrio. En conclusión, dos dosis de MPA (5mg/kg; i.m.) no tienen un efecto significativo sobre la expresión de ER y PR; sin embargo, inhiben la proliferación celular en la región basal del endometrio, el cual incluye a estroma, capa de células subepiteliales, estratos compacto y esponjoso. El efecto clínico a largo plazo de este tratamiento debe ser evaluado en estudios posteriores.

Função sexual pós-histerectomia: quais os impactos e aspectos técnicos envolvidos? / Sexual function after hysterectomy: what are the impacts and technical aspects involved?

Objetivo: Identificar o impacto da histerectomia para patologias benignas sobre a sexualidade feminina. Métodos: Revisão de literatura com busca na plataforma PubMed, sendo selecionados 23 artigos em português e inglês publicados entre 2016 e 2021. Resultados: Foi descrita, majoritariamente, melhora na função sexual após histerectomia, semelhante às abordagens totais ou supracervicais e independentemente da via de acesso cirúrgico, apesar de impacto ligeiramente menor com a via laparoscópica. Na laparoscopia, houve melhor desfecho sexual no fechamento da cúpula vaginal, quando comparado ao fechamento via vaginal. Ademais, a ooforectomia concomitante apresentou resultados conflitantes e inconclusivos. Conclusão: A histerectomia afeta positivamente a saúde sexual feminina e aspectos técnicos podem interferir na função sexual, porém os dados são limitados. Devido à importância do tema, necessitam-se de mais estudos com metodologias padronizadas para possibilitar análises mais detalhadas.

Objective: To identify the impact of hysterectomy for benign pathologies on female sexuality. Methods: Literature review with search on PubMed platform, being selected 23 articles in Portuguese and English published between 2016 and 2021. Results: Improvement in sexual function after hysterectomy was mostly described, being similar in total or supracervical approaches and independent of the surgical access route, although it had slightly lower impact when laparoscopic. In the laparoscopic approach, there was better sexual outcome in the vaginal dome closure when compared to vaginal closure. In addition, concomitant oophorectomy showed conflicting and inconclusive results. Conclusion: Hysterectomy positively affects female sexual health and technical aspects may interfere with sexual function, but data are limited. Due to the importance of the theme, more studies with standardized methodologies are needed to enable more detailed analyses.

Uterine POLE mutant endometrioid carcinoma combined with human papilloma virus-associated cervical adenocarcinoma: A case report and literature review / 北京大学学报(医学版)

Independent primary uterine and cervical adenocarcinoma are rare and difficult to identify their origins, which makes treatment decision difficult. A 46-year-old female with endometrioid carcinoma and adenocarcinoma, human papilloma virus (HPV)-associated of the uterine cervix was reported. The patient presented with increased menstrual flow, contact bleeding and watery leucorrhea for more than one year, and the imaging findings showed abnormal uterine morphology, irregular margins, and multiple abnormal signals in uterine cavity and myometrium, which suggested multiple leiomyomas of the uterus. The signal intensity in the right muscle layer was markedly enhanced, suggesting a smooth muscle tumor of uncertain malignant potential. A large number of cystic hypointensity was seen in the cervix, and multiple cysts were considered. The initial preoperative diagnosis was multiple leiomyoma of the uterus, and a hysterectomy operation was planned. During the operation, the uterus was sent for frozen sections. There was a mass in the endometrium of the fundus, with a soft grayish-red cut surface and a clear border with the myometrium, and there was a grayish-white nodule in the cervix with a hard grayish-white cut surface. The two masses were well demarcated from each other, and the distance between them was 30 mm. The result of the frozen sections indicated the malignant tumor of the endometrium, and the extended hysterectomy+pelvic lymphadenectomy+partial resection of the greater omentum was performed. After the operation, the paraffin sections were sent to the Department of Pathology of the Peking University Third Hospital for histochemistry, POLE gene sequencing and HPV RNAscope tests, and the final diagnosis was a synchronous endometrioid carcinoma (POLE-mutant according to the WHO classification) and an adenocarcinoma, HPV-associated of the uterine cervix. Now the patient had been treated with 2 cycles of chemotherapy and her condition was fine. Through the analysis of the histological, immunohistochemical and molecular detection results of this case, the importance of applying HPV RNAscope and TCGA molecular typing in the diagnosis of cervical adenocarcinomas and endometrial carcinomas was emphasized. At the same time, gynecologists should not blindly rely on intraoperative frozen sections, and should pay attention to preoperative pathological examination, and make appropriate operation methods according to the results in order to prevent passivity in the surgery.

Effects of Heliotropium indicum L. on Uterine Involution and Its Underlying Mechanisms: an in vivo and in vitro Study / 中国结合医学杂志

OBJECTIVE@#To investigate the effect of Heliotropium indicum L. (H. indicum L.) on uterine involution and its underlying mechanisms in both in vivo and in vitro study.@*METHODS@#For in vivo studies, postpartum rats were randomly divided into 2 groups (n=24 for each): control group and treated group which were orally and daily administered with ethanolic extract of H. indicum L. (250 mg/kg body weight) until day 5 of postpartum. Uteri were collected for analysis of weight, cross-sectional area, collagen cross-sectional area, and collagen content on postpartum day 1, 3, and 5 (n=8 for each) from both groups. Blood samples were collected for hepatotoxicity and 17β-estradiol (E2) measurement. For in vitro studies, the extract effects on uterine contraction at half maximum effective concentration of 2.50 mg/mL were studied in organ bath system for at least 20 min.@*RESULTS@#Uterine parameters were significantly decreased after treated with extract of H. indicum L. (P<0.05). H. indicum L. extract significantly accelerated the reduction of those parameters and significantly decreased E2 (P<0.05). The extract facilitated uterine involution with no hepatotoxicity. H. indicum L. extract significantly stimulated uterine contraction (P<0.05) and synergized with oxytocin, prostaglandin and its precursor, linoleic acid. By investigating the different sequencing of the extract with the additional stimulants (added before or after), the two showed antagonistic effects, but still showed potentiated force when compared with control (without the stimulants).@*CONCLUSIONS@#The underlying mechanisms by which H. indicum L. facilitated uterine involution might be due to reducing E2 which induces collagenase activity, leading to decreases in uterine weight and size and stimulating uterine contraction. Our study provides new findings for future drug development for facilitating uterine involution with H. indicum L.

Effects of electroacupuncture on NLRP3 inflammasome and pyroptosis protein GSDMD in uterine tissue in rats with primary dysmenorrhea / 中国针灸

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on NLRP3 inflammasome and its downstream protein gastermin D (GSDMD) in rats with primary dysmenorrhea (PDM), and to explore the potential mechanism of EA on the treatment of PDM.@*METHODS@#Forty healthy female SD rats without pregnancy were randomly divided into a control group, a model group, an EA group and an ibuprofen group, 10 rats in each group. PDM model was prepared by injection of estradiol benzoate and oxytocin. Except the control group, the rats in each group were subcutaneously injected with estradiol benzoate for 10 days, and oxytocin was injected on the 11th day. The rats in the EA group were intervened with EA (dense wave, frequency of 50 Hz) at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) at the same time of modeling, once a day, 20 min each time, for 10 consecutive days. The rats in the ibuprofen group were treated with 0.8 mL of ibuprofen by gavage (concentration of ibuprofen solution was 1.25 mg/mL) for 10 consecutive days. After modeling, the writhing reaction was observed. After intervention, the HE staining method was used to observe the histological morphology of uterus and evaluate the pathological damage score of uterus; ELISA method was used to detect the serum levels of prostaglandin E2 (PGE2) and prostaglandin F2α (PGF2α); Western blot method was used to detect the protein expression of NLRP3, apoptosis related spot like protein (ASC), caspase-1, GSDMD, GSDMD-N and inflammatory factors (interleukin [IL]-1β, IL-18) in uterine tissue.@*RESULTS@#In the model group, a large number of vacuolar degeneration and death of endometrial epithelial cells, spiral arterioles congestion in lamina propria and neutrophil infiltration were observed. In the EA group, there was a small amount of vacuolar degeneration and death of endometrial epithelial cells, a small amount of spiral arterioles congestion in the lamina propria, and a small amount of neutrophils infiltration. In the ibuprofen group, there was very small number of degeneration and death of endometrial epithelial cells, and no obvious arterial congestion was found in lamina propria, and neutrophil infiltration was occasionally seen. Compared with the control group, in the model group the number of writhing was increased (P<0.01), the writhing reaction score and serum level of PGF2α and PGF2α/PGE2 value were increased (P<0.01), the level of PGE2 was decreased (P<0.01). Compared with the model group, in the EA group and the ibuprofen group the number of writhing were decreased (P<0.05), the latency of writhing was prolonged (P<0.01), the writhing reaction scores and serum levels of PGF2α and PGF2α/PGE2 values were decreased (P<0.05, P<0.01), the levels of PGE2 were increased (P<0.01). Compared with the control group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was increased in the model group (P<0.01). Compared with the model group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was decreased in the EA group and the ibuprofen group (P<0.01, P<0.05). There was no significant difference between the EA group and the ibuprofen group in the above indexes (P>0.05).@*CONCLUSION@#EA could alleviate pain and uterine tissue injury in rats with PDM. The mechanism may be related to the inhibition of the activation of NLRP3 inflammasome in rat uterine tissues, thereby inhibiting pyroptosis and its inflammatory factors release.

Intrauterine Device Totally Embedded in the Bladder Wall:Report of One Case / 中国医学科学院学报

Intrauterine device(IUD)migrating to the bladder is rare,especially the migration far away from the uterus into the bladder wall.Due to no obvious clinical symptom in the early stage and being far away from the uterus,the IUD totally embedded in the bladder wall is prone to misdiagnosis and delay in treatment.We reported one case of such migration,aiming to improve the clinical management of the IUD totally embedded in the bladder wall.

Changes of uterine morphology and endometrial T2 signal intensity in the fibrotic repair secondary to endometrial injury / 中华妇产科杂志

Objective: To investigate the value of uterine morphological parameters and endometrial T2 signal intensity (T2-SI) in evaluating the degree of the fibrotic repair secondary to endometrial injury. Methods: From Sep. 2018 to Feb. 2023, this study prospectively enrolled 29 patients with fibrotic repair secondary to severe endometrial injury (severe group), 17 patients with fibrotic repair secondary to mild to moderate endometrial injury (mild to moderate group), and 40 healthy women of reproductive age (control group) in Nanjing Drum Tower Hospital. The length of uterine cavity (LUC), length of cervix and isthmus (LCI), width of upper uterine cavity (WUUC) and width of lower uterine cavity (WLUC) were measured using magnetic resonance imaging. T2-SI of endometrium and subcutaneous fat of buttocks were measured, and endometrial normalized T2-SI (nT2-SI; T2-SI of endometrium/T2-SI of subcutaneous fat of buttocks) was calculated. Statistical analyses of data were performed using one-way analysis of variance, Mann-Whitney U test, intraclass correlation coefficient, Spearman rho test, area under the receiver operating characteristic curve (AUC). Results: LUC, WUUC, WLUC and endometrial nT2-SI of severe group [(19.7±3.5) mm, (26.9±6.4) mm, (7.9±1.4) mm, 0.73±0.11, respectively] were significantly lower than those of the control group (all P<0.01), while LCI and WUUC/LUC [(51.3±7.3) mm and 1.38±0.34] were significantly higher than those of the control group (all P<0.001). LUC and WLUC of severe group were significantly lower than those of mild to moderate group [(32.4±5.1) mm and (8.8±1.2) mm; all P<0.05], while LCI and WUUC/LUC were significantly higher than those of mild to moderate group [(41.8±8.6) mm and 0.94±0.16; all P<0.001]. LUC and endometrial nT2-SI of mild to moderate group were significantly lower than those of the control group [ (32.4±5.1) vs (35.3±3.5) mm, 0.68±0.13 vs 0.80±0.12; all P<0.01]. LUC, WUUC, WLUC and endometrial nT2-SI were significantly negatively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho:-0.794, -0.441, -0.471 and -0.316, respectively; all P<0.05), while LCI and WUUC/LUC were significantly positively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho: 0.481 and 0.674, respectively; all P<0.05). LUC and WUUC/LUC showed high value in distinguishing severe group from the control group or mild to moderate group (all AUC>0.9, all P<0.001). Conclusion: As noninvasive and quantitative biomarkers, uterine morphological parameters and endometrial nT2-SI could evaluate the degree of the fibrotic repair secondary to endometrial injury.

Effect of Liangfang Wenjing Decoction on expression of key glycolytic enzymes in uterus and ovaries of rats with coagulating cold and blood stasis syndrome / 中国中药杂志

This study aimed to investigate the relationship between coagulating cold and blood stasis syndrome and glycolysis, and observe the intervention effect of Liangfang Wenjing Decoction(LFWJD) on the expression of key glycolytic enzymes in the uterus and ovaries of rats with coagulating cold and blood stasis. The rat model of coagulating cold and blood stasis syndrome was established by ice-water bath. After modeling, the quantitative scoring of symptoms were performed, and according to the scoring results, the rats were randomly divided into a model group and LFWJD low-, medium-and high-dose groups(4.7, 9.4, 18.8 g·kg~(-1)·d~(-1)), with 10 in each group. Another 10 rats were selected as the blank group. After 4 weeks of continuous administration by gavage, the quantitative scoring of symptoms was repeated. Laser speckle flowgraphy was used to detect the changes of microcirculation in the ears and uterus of rats in each group. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of uterus and ovaries of rats in each group. The mRNA and protein expressions of pyruvate dehydrogenase kinase 1(PDK1), hexokinase 2(HK2) and lactate dehydrogenase A(LDHA) in the uterus and ovaries of rats were examined by real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot, respectively. The rats in the model group showed signs of coagulating cold and blood stasis syndrome, such as curl-up, less movement, thickened veins under the tongue, and reduced blood perfusion in the microcirculation of the ears and uterus, and HE staining revealed a thinning of the endometrium with disorganized arrangement of epithelial cells and a decrease in the number of ovarian follicles. Compared with the model group, the treatment groups had alleviated coagulating cold and blood stasis, which was manifested as red tongue, reduced nail swelling, no blood stasis at the tail end as well as increased blood perfusion of the microcirculation in the ears and uterus(P<0.05 or P<0.01). Among the groups, the LFWJD medium-and high-dose groups had the most significant improvement in coagulating cold and blood stasis, with neatly arranged columnar epithelial cells in uterus, and the number of ovarian follicles was higher than that in the model group, especially mature follicles. The mRNA and protein expressions of PDK1, HK2, LDHA in uterus and ovaries were up-regulated in the model group(P<0.05 or P<0.01), while down-regulated in LFWJD medium-and high-dose groups(P<0.05 or P<0.01). The LFWJD low-dose group presented a decrease in the mRNA expressions of PDK1, HK2 and LDHA in uterus and ovaries as well as in the protein expressions of HK2 and LDHA in uterus and HK2 and PDK1 in ovaries(P<0.05 or P<0.01). The therapeutic mechanism of LFWJD against coagulating cold and blood stasis syndrome is related to the down-regulation of key glycolytic enzymes PDK1, HK2 and LDHA, and the inhibition of glycolytic activities in uterus and ovaries.

Value of basal luteinizing hormone level combined with uterine volume measurement in the early diagnosis of central precocious puberty in girls with different Tanner stages / 中国当代儿科杂志

OBJECTIVES@#To study the value of basal luteinizing hormone (LH) level combined with uterine volume measurement in the early diagnosis of central precocious puberty (CPP) in girls with different Tanner stages.@*METHODS@#A retrospective analysis was performed on the girls who presented with breast development before the age of 8 years and attended the Third Affiliated Hospital of Zhengzhou University from January 2017 to September 2022. According to the results of gonadotropin-releasing hormone (GnRH) agonist test, the girls with peak LH ≥5.0 IU/L and peak LH/follicle stimulating hormone ≥0.6 were enrolled as the positive group, and the other girls were enrolled as the negative group. The two groups were compared in terms of the basal LH level and uterine volume. The receiver operating characteristic (ROC) curve was used to analyze their value in the early diagnosis of CPP.@*RESULTS@#For the girls with Tanner B2 and B3 stages, the positive group had significantly higher basal LH level and uterine volume than the negative group (P<0.05). The basal LH level had an optimal cut-off value of 0.325 IU/L and 0.505 IU/L respectively in the diagnosis of Tanner stage B2/B3 CPP, while uterine volume had an optimal cut-off value of 1.639 mL and 2.158 mL respectively. Basal LH level combined with uterine volume measurement had a significantly larger area under the ROC curve than uterine volume measurement alone (P<0.001), but with no significant difference compared with that of basal LH level measurement alone (P>0.05).@*CONCLUSIONS@#Basal LH level combined with uterine volume measurement is valuable in the early diagnosis of CPP in girls with different Tanner stages, which provides a basis and guiding significance for clinical diagnosis of CPP.

Bisphenol S increases cell number and stimulates migration of endometrial epithelial cells / Journal of the ASEAN Federation of Endocrine Societies

Objective@#To determine whether bisphenol S (BPS), a common substitute for bisphenol A (BPA), induces cell proliferation and migration in human endometrial epithelial cells (Ishikawa) and adult mouse uterine tissues.@*Methodology@#Human endometrial Ishikawa cells were exposed to low doses of BPS (1 nM and 100 nM) for 72 hours. Cell proliferation was assessed through the viability assays MTT and CellTiter-Glo®. Wound healing assays were also used to evaluate the migration potential of the cell line. The expression of genes related to proliferation and migration was also determined. Similarly, adult mice were exposed to BPS at a dose of 30 mg/kg body weight/day for 21 days, after which, the uterus was sent for histopathologic assessment.@*Results@#BPS increased cell number and stimulated migration in Ishikawa cells, in association with the upregulation of estrogen receptor beta (ESR2) and vimentin (VIM). In addition, mice exposed to BPS showed a significantly higher mean number of endometrial glands within the endometrium.@*Conclusion@#Overall, in vitro and in vivo results obtained in this study showed that BPS could significantly promote endometrial epithelial cell proliferation and migration, a phenotype also observed with BPA exposure. Hence, the use of BPS in BPA-free products must be reassessed, as it may pose adverse reproductive health effects to humans.

Necrosis uterina tras sutura de compresión hemostática: reporte de caso y revisión de la literatura / Uterine necrosis following hemostatic compression suture: case report and review of the literature

Objetivos: presentar un caso de necrosis uterina tras técnica de sutura hemostática por hemorragia posparto y hacer una revisión de la literatura para determinar la técnica de sutura utilizada, los hallazgos clínicos, la técnica diagnóstica y el tratamiento realizado en los casos clínicos descritos. Materiales y métodos: se presenta el caso de una mujer de 34 años que consultó por dolor abdominal al octavo día tras cesárea por placenta previa, que precisó sutura de B-Lynch por atonía uterina y cuyo diagnóstico fue necrosis uterina. La paciente requirió histerectomía abdominal total, con evolución satisfactoria. Se realizó una búsqueda sistemática de la literatura en las bases de datos Medline vía Pubmed, Embase y Web of Science. Se buscaron series y reportes de casos y cohortes de mujeres con necrosis uterina posterior al uso de suturas de compresión uterina para control de hemorragia posparto. Se analizaron variables sociodemográficas y clínicas al diagnóstico, técnica de sutura, pruebas diagnósticas y tratamiento. Resultados: se incluyeron 23 estudios con 24 pacientes. El 83 % de las necrosis ocurrieron tras cesárea. La técnica más utilizada fue B-Lynch (66 %), seguida de Cho (25 %). Los síntomas más frecuentes fueron fiebre y dolor abdominal. La prueba diagnóstica más utilizada fue la tomografía computarizada (9 de 24 casos). En la mayoría de casos se realizó histerectomía (75 %). Conclusiones: la necrosis de la pared uterina es una complicación infrecuente pero grave. Sería recomendable el diseño de cohortes de seguimiento de mujeres sometidas a estos procedimientos para determinar la incidencia de complicaciones asociadas.

Objectives: To present a case of uterine necrosis following hemostatic suturing to control postpartum bleeding, and to review the literature in order to identify the suture techniques employed, clinical findings, diagnostics and treatment in the clinical cases described. Materials and Methods: A 34-year-old woman presenting with abdominal pain eight days after cesarean delivery due to placenta previa who required B-Lynch compression suture due to uterine atony, and who was diagnosed with uterine necrosis. The patient underwent total abdominal hysterectomy with a satisfactory recovery. A systematic literature search was conducted in the Medline vía Pubmed, Embase and Web of Science databases. The search included case series and reports, and cohorts of women with uterine necrosis following the use of uterine compression sutures for postpartum bleeding. The analysis included sociodemographic and clinical variables at the time of diagnosis, suturing technique, diagnostic tests and treatment. Results: Overall, 23 studies with 24 patients were included. Of all necrosis cases, 83% occurred following cesarean section. B-Lynch was the suturing technique most frequently used (66 %), followed by the Cho suture (25 %). The most frequent symptoms were fever and abdominal pain. The most commonly used diagnostic test was computed tomography (9/24 cases). Hysterectomy was performed in the majority of cases (75 %). Conclusions: Although rare, uterine wall necrosis is a serious complication. It would be advisable to design follow-up cohort studies of women undergoing these procedures in order to determine the incidence of associated complications.
