RESUMO
Since the last decade, iatrogenic injuries of ureter are increasingly common. We describe a case of 36-year-old young female, who underwent emergency cesarean section, presented to us after 3 weeks, with clear vaginal discharge. After evaluated with clinical examination and radiological investigations, she was found to have left uretero-uterine fistula and was successfully treated with robotic-assisted left uretero-uterine fistula repair by Lich-Gregoir technique.

OBJECTIVE: Endometrial polyp (EP) is a type of pathology that is quite common in clinical practice. Although its exact etiology is not fully known, there is evidence to support that it is sensitive to hormonal stimuli. We aimed to investigate the relationship between kisspeptin (KP) and EP by comparing the genetic (tissue-blood) and immunohistochemical (IHC) expression of KP in EP lesions in patients with normal endometrial findings. MATERIALS AND METHODS: A prospective case-control study of 50 patients with EP (N = 25) and normal endometrial findings (N = 25) on biopsy and/or excision material was performed. Blood and biopsy samples obtained from all patients were stored at -80 °C. KP gene expression levels were determined from paraffin blocks, and peripheral venous blood samples obtained from biopsy specimens and IHC-H-score analysis were performed from paraffin blocks. EP and matched controls were compared for KP. RESULTS: After IHC, the KP H-score of the control group was higher than the EP group, and this difference was statistically significant; H-score: control: 5 (++; 1-15); polyp: 1 (+; 0-12) (P < 0.05). Although KP expression in both tissue and blood was higher in the control group than in the EP group, this difference was not statistically significant (P > 0.05). No significant correlation was found between IHC H-score and KP expression levels in tissue and blood. According to the ROC analysis, the tissue and blood KP expression cut-off value and area under the curve (AUC) predicting the likelihood of developing EP were not significant (tissue KP: 1.04, AUC: 0.570, P = 0.388, sensitivity 56%, specificity 60%, Blood KP: 1.06, AUC: 0.569, P = 0.401, sensitivity 80%, specificity 40%). CONCLUSIONS: Decreased KP expression level in EP lesions may predict the diagnosis of EP, and in the future, KP may have therapeutic potential for benign gynecological pathologies such as polyps.

IL-33 belongs to the inflammatory factor family and is closely associated with the inflammatory response. However, its role in the development of intrauterine adhesions (IUAs) remains unclear. In this study, the role of IL-33 in the formation of IUAs after endometrial injury was identified via RNA sequencing after mouse endometrial organoids were transplanted into an IUA mouse model. Major pathological changes in the mouse uterus, consistent with the expression of fibrotic markers, such as TGF-ß, were observed in response to treatment with IL-33. This finding may be attributed to activation of the phosphorylation of downstream MAPK signaling pathway components, which are activated by the release of IL-33 in macrophages. Our study provides a novel mechanism for elucidating IUA formation, suggesting a new therapeutic strategy for the prevention and clinical treatment of IUAs.

Endometrial polyps commonly contribute to female infertility, and hysteroscopic resection is the established surgical approach for their treatment. Numerous resection methods are available, with the most used and cost-effective options being cold resection employing micro-scissors or hot resection using an electric loop. However, both methods involve sharp resection, posing a challenge in achieving complete polyp removal while avoiding damage to the uterine endometrium. To address this issue, this study proposes an innovative approach: the combined use of the 6 Fr micro-scissors and forceps under hysteroscopy. The method entails utilizing 6 Fr micro-scissors to initially remove large polyps, followed by using 6 Fr micro-forceps to extract the remaining polyp tissue expeditiously and bluntly near the basal layer of the endometrium. This approach not only prevents surgical damage to the basal layer of the endometrium but also mitigates the risk of residual polyps resulting from incomplete resection. This method is particularly suitable for women with fertility requirements, offering additional considerations for the selection of treatment options for endometrial polyp resection.

BACKGROUND: This study aimed to determine the effect and mechanism of the Decoction of Yougui Wan combined with Wuzi Yanzong Wan (DYWWYW), a traditional Chinese herbal formula, in a mouse model with thin endometrium induced by 95% ethanol. METHODS: Thin endometrium mice were treated with progynova (0.002 mg) as well as a low and high dose of DYWWYW (0.05 and 0.5 mL DYWWYW, respectively, diluted in 2 mL normal saline). Western blotting and qRT-PCR analyses were performed to determine the protein and mRNA expression levels, respectively, of integrin αγß3 and leukaemia inhibitor factor (LIF) in uterus tissues. Serum oestradiol and progesterone concentrations were determined via ELISA. The remaining thin endometrium mice were mated with male mice, and the number of embryos implanted in the different groups was calculated. RESULTS: A high dose of DYWWYW effectively ameliorated the injury of endometrium caused by 95% ethanol. The levels of oestradiol, progesterone, αγß3 and LIF in thin endometrium mice treated with a high dose of DYWWYW were also significantly elevated. Additionally, a high dose of DYWWYW remarkably increased the number of embryo implantations in mice with thin endometrium. CONCLUSION: DYWWYW has improvement effects on thin endometrium by elevating the levels of endogenous oestradiol, progesterone, αγß3, and LIF in a mouse model.
During the reproductive cycle, endometrium thickness of more than 7 mm is considered as a cut-off value for successful embryo implantation. Currently, although therapies for the improvement of endometrium thickness such as sildenafil, endometrial scraping, granulocyte colony-stimulating factor and low dose of aspirin have been tried, the effects on patients are not consistent. Consequently, it is necessary to seek novel therapies to increase endometrium thickness effectively. A 95% ethanol-induced thin endometrium female ICR mouse model was established in this study. High dose of Decoction of Yougui Wan combined with Wuzi Yanzong Wan (DYWWYW) effectively ameliorated the injury of endometrium and remarkably increased the number of embryo implantations in thin endometrium mice. Additionally, the levels of some key indicators including oestradiol, progesterone, αγß3, and LIF were also increased in thin endometrium mice treated with high dose of DYWWYW. Therefore, DYWWYW was feasible in increasing endometrium thickness in a mouse model.

OBJECTIVE: To assess the efficacy of mechanical resection through TruClear™ hysteroscopy in patients with endometrial polyps and submucosal fibroids. STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Obstetrics and Gynaecology, Shifa International Hospital, Islamabad, Pakistan, from June 2018 to 2022. METHODOLOGY: Patients diagnosed with endometrial polyps and submucosal fibroids confirmed by abdominal or transvaginal ultrasonography were included. Patients having a history of congestive cardiac failure, chronic kidney disease, and bleeding diathesis were excluded from the study. Data about the complete removal of pathology (endometrial polyps and submucosal fibroids), mean operating time, and postoperative complications such as bleeding and perforation were extracted. The follow-up was set up to 6 months after the procedure. RESULTS: The average age of the 45 patients was 35.62 ± 7.46 years. Heavy menstrual bleeding was the most prevalent symptom, seen in 73.3% of cases, followed by irregular vaginal bleeding (IVB) in 11.1% of cases. The most frequent disease identified by sonography was a polyp in 21 (47%) instances, followed by submucosal fibroids in 12 (27%) cases, mixed pathology in 10 (22%), and malignancy in 2 (4%) cases. The overall average operative time was 36.46 ± 24.94 minutes. A hundred percent removal of lesions was observed in this study. Persistent symptoms were observed in 13% of patients after the surgery so they were treated with other interventions. The most common intervention was an intrauterine hormonal device. Intraoperative bleeding was observed in only one patient and was managed by intraoperative intrauterine balloon insertion. The recurrence rate was 8.9% (4/45). CONCLUSION: TruClear™ hysteroscopy showed a major advantage in the successful and complete removal of the pathology, low operation time, and complications. KEY WORDS: Fibroids, Hysteroscopy, Polyps, Endometrial resection, Menstrual bleeding.

Objective: To investigate the effect of autologous platelet-rich plasma (PRP) perfusion on the levels of cytokines in uterine drainage fluid in patients with moderate to severe intrauterine adhesions (IUA) following hysteroscopic adhesiolysis. Methods: Thirty patients with moderate to severe IUA who underwent hysteroscopic adhesiolysis at Beijing Obstetrics and Gynecology Hospital, Capital Medical University from November 2020 to March 2021 were randomly divided into two groups: the PRP group (15 patients with placement of intrauterine-suitable balloons and PRP infusion) and the control group (15 patients with placement of intrauterine-suitable balloons only). For all patients, the channel switch was opened 48 hours after the surgery. The drainage fluid of the uterine cavity was collected using syringes through the proximal end of the drainage channel switch at 24 hours after the surgery and through the drainage channel directly at 48, 72, 96, and 120 hours after the surgery, and the levels of related cytokines including platelet-derived growth factor BB (PDGF-BB), vascular endothelial growth factor A (VEGF-A), insulin-like growth factor 1 (IGF-1) and transforming growth factor-ß1 (TGF-ß1) in the drainage fluid of the uterine cavity were evaluated, respectively. Results: (1) The changes in volumes of uterine cavity drainage fluid: the total drainage fluid volumes of the PRP group and the control group in 120 hours after the surgery were (21.8±2.9) and (22.7±2.7) ml, respectively, and there was no statistically significant difference between the two groups (t=-0.847, P>0.05). No significant differences were found in the volumes of drainage fluid between the two groups at 72, 96, and 120 hours after the surgery (all P>0.05). (2) Variation in cytokine levels in the uterine cavity drainage fluid: â PDGF-BB: median PDGF-BB levels at 24 and 48 hours after the surgery in the PRP group (6.6 and 9.6 µg/L, respectively) were significantly higher than those in the control group (4.7 and 2.7 µg/L, respectively; all P<0.05). There were no significant differences in PDGF-BB levels between the two groups at 72, 96, and 120 hours after the surgery (all P>0.05). â¡ VEGF-A: median VEGF-A levels at 24 and 48 hours after the surgery in the PRP group (3.5 and 2.8 µg/L, respectively) were significantly higher than those in the control group (1.6 and 1.2 µg/L, respectively; all P<0.05). There were no significant differences in VEGF-A levels between the two groups at 72, 96, and 120 hours after the surgery (all P>0.05). ⢠IGF-1: median IGF-1 level at 48 hours after the surgery in the PRP group was significantly higher than that in the control group (39.5 vs 8.6 µg/L, P<0.05). No significant differences were found in IGF-1 levels at 24, 72, 96, and 120 hours after the surgery between the two groups (all P>0.05). ⣠TGF-ß1: There were no significant differences in TGF-ß1 levles between the two groups at 24, 48, 72, 96, and 120 hours after the surgery (all P>0.05). Conclusions: PRP perfusion following hysteroscopic adhesiolysis may increase the levels of PDGF-BB, VEGF-A, and IGF-1 in the uterine cavity drainage fluid, which plays a beneficial role in improving wound microvascular formation, reducing adhesion reformation, and promoting endometrial regeneration and repair.

A G4P4 woman in her 30s with a type II vesicouterine fistula, as defined by the Jozwik classification system, presented with symptoms of menouria, vaginal menses and urinary incontinence 8 years after caesarean delivery, the time of probable origination of the fistula tract. Transvaginal ultrasound identified a fistula tract communicating between the bladder and uterus, a rare finding that many years remote from caesarean delivery. Traditional surgical technique includes laparoscopic, abdominal and endoscopic methods of repair, sometimes using a transvesical approach. Transvesical repair can be associated with subsequent inpatient hospital stays and prolonged catheterisation. Our technique proposes a transvaginal surgical approach as an outpatient procedure with decreased operating time (40 min), postoperative pain and catheterisation requirement. It is the authors' belief that a transvaginal approach is less invasive and allows for better preservation of the uterus for future pregnancies and vaginal deliveries, as desired by the patient.

BACKGROUND: Intrauterine adhesions (IUA) are a challenging clinical problem in reproductive infertility. The most common causes are intrauterine surgery and abortions. We aimed to investigate whether early second-look office hysteroscopy can prevent IUA. METHODS: A single-center, prospective, two-armed, randomized controlled trial was designed to explore the efficacy of early office hysteroscopy after first-trimester induced abortion (suction dilatation and curettage [D&C]) and to further analyze fertility outcomes. Women aged 20-45 years undergoing suction D&C and desiring to conceive were recruited. Between October 2019 and September 2022, 66 women were enrolled, of whom 33 were allocated to group A (early hysteroscopy intervention). The women in intervention group A were planned to receive 2 times of hysteroscopies (early and late). In group B, women only underwent late (6 months post suction D&C) hysteroscopy. RESULTS: The primary outcome was the IUA rate assessed using office hysteroscopy 6 months after artificial abortion. Secondary outcomes included menstrual amount/durations and fertility outcomes. In intervention group A, 31 women underwent the first hysteroscopy examination, and 15 completed the second. In group B (late hysteroscopy intervention, 33 patients), 16 completed the hysteroscopic exam 6 months after an artificial abortion. Twenty-one women did not receive late hysteroscopy due to pregnancy. The IUA rate was 16.1% (5/31) at the first hysteroscopy in group A, and no IUA was detected during late hysteroscopy. Neither group showed statistically significant differences in the follow-up pregnancy and live birth rates. CONCLUSIONS: Early hysteroscopy following suction D&C can detect intrauterine lesions. IUA detected early by hysteroscopy can disappear on late examination and become insignificant for future pregnancies. Notably, the pregnancy outcomes showed a favorable trend in the early hysteroscopy group, but there were no statistically significant differences.

BACKGROUND: Both the trauma of endometrium and hysteroscopic adhesiolysis can lead to a high rate of placenta accreta spectrum (PAS) in women with intrauterine adhesion (IUA). This study analysed the impact of time interval from adhesiolysis to pregnancy on PAS in IUA women. METHODS: Patients diagnosed with IUA who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020 were included in this case-series study. Clinical data were obtained from electronic medical records and telephone interviews. RESULTS: Among a total of 102 IUA women with successful pregnancies, 8 (7.8%) suffered from miscarriages with PAS, and 94 (92.2%), 47 with PAS and 47 without PAS, had successful delivery. The total prevalence of PAS in pregnant women with IUA was 53.9% (55/102). The average time from adhesiolysis to pregnancy in the PAS group was significantly longer than in the non-PAS group (14.2 ± 5.7 vs. 10.3 ± 4.4 months, p = 0.000). Regression analysis showed that AFS grade (OR = 7.40, 95% CI 1.38-39.73, p = 0.020) and adhesiolysis to pregnancy interval time between 12 and 24 months (OR = 12.09, 95% CI 3.76-38.83, p = 0.000) were closely related to PAS. A Kaplan-Meier analysis showed the median interval time to PAS was 16.00 months (95% CI 15.11-16.89). CONCLUSIONS: We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for PAS in IUA women.
Both the trauma of endometrium and hysteroscopic adhesiolysis can result in a high rate of placenta accreta spectrum in women with intrauterine adhesion.

The integration of barrier materials with pharmacological therapy is a promising strategy to treat intrauterine adhesions (IUAs). However, most of these materials are surgically implanted in a fixed shape and incongruence with the natural mechanical properties of the uterus, causing poor adaptability and significant discomfort to the patients. Herein, an injectable, biodegradable, and mechanically adaptive hydrogel loaded with platelet-rich plasma (PRP) is created by Lserine and allyl functionalized chitosan (ACS) to achieve efficient, comfortable, and minimally invasive treatment of IUAs. Lserine induces fast gelation and mechanical reinforcement of the hydrogel, while ACS introduces, imparting a good injectability and complaint yet strong feature to the hydrogel. This design enables the hydrogel to adapt to the complex geometry and match the mechanical properties of the uterine. Moreover, the hydrogel exhibits proper degradability, sustained growth factors (GFs) of PRP release ability, and good biocompatibility. Consequently, the hydrogel shows promising therapeutic efficacy by reducing collagen fiber deposition and facilitating endometrium cell proliferation, thereby restoring the fertility function of the uterus in an IUAs model of rats. Accordingly, the combination of Lserine and ACS-induced hydrogel with such advantages holds great potential for treating IUAs. STATEMENT OF SIGNIFICANCE: This research introduces a breakthrough in the treatment of intrauterine adhesions (IUAs) with an injectable, biodegradable and mechanically adaptive hydrogel using Lserine and allyl functionalized chitosan (ACS). Unlike traditional surgical treatments, this hydrogel uniquely conforms to the uterus's geometry and mechanical properties, offering a minimally invasive, comfortable, and more effective solution. The hydrogel is designed to release growth factors from platelet-rich plasma (PRP) sustainably, promoting tissue regeneration by enhancing collagen fiber deposition and endometrium cell proliferation. Demonstrated efficacy in a rat model of IUAs indicates its great potential to significantly improve fertility restoration treatments. This advancement represents a significant leap in reproductive medicine, promising to transform IUAs treatment with its innovative approach to achieving efficient, comfortable, and minimally invasive therapy.

Intrauterine adhesion (IUA) is manifestations of endometrial fibrosis and excessive extracellular matrix deposition. C1q/tumor necrosis factor-related protein-6 (CTRP6) is a newly identified adiponectin paralog which has been reported to modulate the fibrosis process of several diseases; however, the endometrial fibrosis function of CTRP6 remains unknown. Our study aimed to assess the role of CTRP6 in endometrial fibrosis and further explore the underlying mechanism. Here, we found that the expression of CTRP6 was downregulated in the endometrial tissues of IUA. In vitro experiments demonstrated the reduced level of CTRP6 in facilitated transforming growth factor-ß1 (TGF-ß1)-induced human endometrial stromal cells (HESCs). In addition, CTRP6 inhibited the expression of α-smooth muscle actin (α-SMA) and collagen I in TGF-ß1-treated HESCs. Mechanistically, CTRP6 activated the AMP-activated protein kinase (AMPK) and protein kinase B (AKT) pathway in HESCs, and AMPK inhibitor (AraA) or PI3K inhibitor (LY294002) pretreatment abolished the protective effect of CTRP6 on TGF-ß1-induced fibrosis. CTRP6 markedly decreased TGF-ß1-induced Smad3 phosphorylation and nuclear translocation, and AMPK or AKT inhibition reversed these effects. Notably, CTRP6-overexpressing treatment alleviated the fibrosis of endometrium in vivo. Therefore, CTRP6 ameliorates endometrial fibrosis, among which AMPK and AKT are essential for the anti-fibrotic effect of CTRP6 via the Smad3 pathway. Taken together, CTRP6 may be a potential therapeutic target for the treatment of intrauterine adhesion.

OBJECTIVE: To analyze the efficacy of levonorgestrelintrauterine system, Drospirenone & ethinylestradiol tablets (II), and dydrogesterone in preventing the recurrence of endometrial polyps after hysteroscopic endometrial polypectomy. METHODS: One hundred seventy patients who underwent hysteroscopic endometrial polypectomy in the Gynecology Department of Tianmen First People's Hospital in Hubei Province from January 2022 to June 2023 were randomly divided into the levonorgestrelintrauterine system group, Drospirenone & ethinylestradiol tablets (II) group, dydrogesterone group, and a control group. The recurrence rates, endometrial thickness, and menstrual volume changes at 6 and 12 months post-operation were compared among these four groups. RESULTS: The recurrence rates in the levonorgestrelintrauterine system group, Drospirenone & ethinylestradiol tablets (II) group, and dydrogesterone group were lower than the control group, with statistical significance (P < 0.01), with the levonorgestrelintrauterine system group having the lowest recurrence rate. The endometrial thickness at 6 and 12 months post-operation in the levonorgestrelintrauterine system group, Drospirenone & ethinylestradiol tablets (II) group, and dydrogesterone group was thinner than that of the control group and thinner than pre-operation, with statistical significance (P < 0.01). The menstrual volume at 3 months post-operation in the levonorgestrelintrauterine system group, Drospirenone & ethinylestradiol tablets (II) group, and dydrogesterone group was significantly less than the control group, and less than the pre-operation volume. CONCLUSION: Dydrogesterone, drospirenone & ethinylestradiol tablets (II), and levonorgestrelintrauterine system all play a role in preventing the recurrence of endometrial polyps, but levonorgestrelintrauterine system is significantly better than dydrogesterone and Drospirenone & ethinylestradiol tablets (II) in terms of postoperative recurrence rate, endometrial thickness, menstrual changes, and compliance, and is worth promoting in clinical application.

BACKGROUND: Intrauterine adhesion (IUA) as a prevalent gynecological disease is developed from infection or trauma. However, therapeutic strategies to repair damaged endometrium are relatively limited. Emerging studies have shed light on the crucial role of endometrial stromal cells (EnSCs) in the process of uterine endometrial regeneration. EnSCs isolated from the uterine endometrium have similar characteristics to mesenchymal stem cells (MSCs). However, it is still unknown whether EnSCs could be used as donor cells to treat IUA. The aim of this study was to evaluate the potential efficacy of EnSCs in treating rat IUA. METHODS: Human EnSCs were isolated from the endometrial tissue of healthy female donors and subjected to extensive expansion and culture in vitro. Immunofluorescence, flow cytometry, cell proliferation assay, trilineage differentiation experiment, and decidualization assay were used to characterize the biological properties of EnSCs. We evaluated the immunoregulatory potential of EnSCs by analyzing their secreted cytokines and conducting bulk RNA sequencing after IFN-γ treatment. After EnSCs were transplanted into the uterine muscle layer in IUA rats, their therapeutic effects and underlying mechanisms were analyzed using histological analysis, Q-PCR, fertility and pregnancy outcome assay, and transcriptome analysis. RESULTS: We successfully isolated EnSCs from the endometrium of human donors and largely expanded in vitro. EnSCs exhibited characteristics of mesenchymal stem cells and retained responsiveness to sex hormones. Following IFN-γ stimulation, EnSCs upregulated the anti-inflammatory cytokines and activated immunosuppressive molecules. Xenogeneic transplantation of EnSCs successfully repaired injured endometrium and significantly restored the pregnancy rate in IUA rats. Mechanistically, the therapeutic effects of EnSCs on IUA endometrium functioned through anti-inflammation, anti-fibrosis and the secretion of regeneration factor. CONCLUSIONS: Due to their large expansion ability, immunoregulatory properties, and great potential in treating IUA, EnSCs, as a valuable source of donor cells, could offer a potential treatment avenue for injury-induced IUA.

OBJECTIVE: To compare inpatient hospital costs and complication rates within the 90-day global billing period among routes of hysterectomy. METHODS: The Premier Healthcare Database was used to identify patients who underwent hysterectomy between 2000 and 2020. Current Procedural Terminology codes were used to group patients based on route of hysterectomy. Comorbidities and complications were identified using International Classification of Diseases codes. Fixed, variable, and total costs for inpatient care were compared. Fixed costs consist of costs that are set for the case, such as operating room time or surgeon costs. Variable costs include disposable and reusable items that are billed additionally. Total costs equal fixed and variable costs combined. Data were analyzed using analysis of variance, t test, and χ 2 test, as appropriate. Factors independently associated with increased total costs were assessed using linear mixed effects models. Multivariate logistic regression was performed to evaluate associations between the route of surgery and complication rates. RESULTS: A cohort of 400,977 patients were identified and grouped by route of hysterectomy. Vaginal hysterectomy demonstrated the lowest inpatient total cost ($6,524.00 [interquartile range $4,831.60, $8,785.70]), and robotic-assisted laparoscopic hysterectomy had the highest total cost ($9,386.80 [interquartile range $6,912.40, $12,506.90]). These differences persisted with fixed and variable costs. High-volume laparoscopic and robotic surgeons (more than 50 cases per year) had a decrease in the cost difference when compared with costs of vaginal hysterectomy. Abdominal hysterectomy had a higher rate of complications relative to vaginal hysterectomy (adjusted odds ratio [aOR] 1.52, 95% CI, 1.39-1.67), whereas laparoscopic (aOR 0.85, 95% CI, 0.80-0.89) and robotic-assisted (aOR 0.92, 95% CI, 0.84-1.00) hysterectomy had lower rates of complications compared with vaginal hysterectomy. CONCLUSION: Robotic-assisted hysterectomy is associated with higher surgical costs compared with other approaches, even when accounting for surgeon volume. Complication rates are low for minimally invasive surgery, and it is unlikely that the robotic-assisted approach provides an appreciable improvement in perioperative outcomes.

Uterine pathologies pose a challenge to women's health on a global scale. Despite extensive research, the causes and origin of some of these common disorders are not well defined yet. This study presents a comprehensive analysis of transcriptome data from diverse datasets encompassing relevant uterine pathologies such as endometriosis, endometrial cancer and uterine leiomyomas. Leveraging the Comparative Analysis of Shapley values (CASh) technique, we demonstrate its efficacy in improving the outcomes of the classical differential expression analysis on transcriptomic data derived from microarray experiments. CASh integrates the microarray game algorithm with Bootstrap resampling, offering a robust statistical framework to mitigate the impact of potential outliers in the expression data. Our findings unveil novel insights into the molecular signatures underlying these gynecological disorders, highlighting CASh as a valuable tool for enhancing the precision of transcriptomics analyses in complex biological contexts. This research contributes to a deeper understanding of gene expression patterns and potential biomarkers associated with these pathologies, offering implications for future diagnostic and therapeutic strategies.

BACKGROUND: Sarcoidosis is a systemic disease that can affect multiple organs. While pulmonary sarcoidosis is most commonly observed, renal sarcoidosis occurs less frequently. We herein report a case of sarcoidosis with an exceptionally rare distribution including renal lesions. CASE PRESENTATION: A 51-year-old Japanese female was referred because of bilateral parotid swelling and renal dysfunction. Computed tomography scan showed the swelling of bilateral kidneys, parotid glands, and uterus. Ga scintigraphy also showed remarkable accumulation in these organs. Renal biopsy and cytological evaluations of parotid gland and uterus were performed and she was diagnosed as sarcoidosis of these organs. Treatment was initiated with prednisolone 40 mg/day and then renal dysfunction subsequently improved. In addition, the swelling of parotid glands and uterus improved and Ga accumulation in each organ had disappeared. CONCLUSION: This is a first case of renal sarcoidosis complicated by parotid glands and uterus lesions. Pathological findings and the reactivity observed in Ga scintigraphy indicated the presence of lesions in these organs.

OBJECTIVES: To observe the effect of electroacupuncture (EA) on the Wnt/ß-catenin signaling pathway and epithelial-mesenchymal transition (EMT)-related proteins in rats with intrauterine adhesions (IUA), so as to explore the possible mechanisms of EA in repairing endometrial damage in IUA. METHODS: Female SD rats were randomly divided into blank, model, EA, and ICG-001 groups, with 10 rats in each group. The IUA model was established by using mechanical scraping combined with lipopolysaccharide infection for double injury. In the EA group, "Guanyuan" (CV4) was needled and EA (2 Hz/15 Hz, 1-2 mA) was applied to "Zusanli" (ST36) and "Sanyinjiao"(SP6) on both sides. In the ICG-001 group, ICG-001 (5 mg/kg), the inhibitor of ß-catenin was intraperitoneally injected. After intervention, samples were taken from 5 rats in each group, and uterine endometrium morphology, endometrial thickness, and gland counts were observed using HE staining. Masson staining was used to assess the degree of fibrosis in the endometrial tissue. Immunohistochemistry was used to detect the positive expression of transforming growth factor ß1 (TGF-ß1), α-smooth muscle actin (α-SMA), fibronectin (FN), connective tissue growth factor (CTGF), type I collagen (Col- â ), glycogen synthase kinase-3ß (GSK-3ß), ß-catenin, E-cadherin, N-cadherin, and Vimentin in the endometrial tissue. Western blot was used to detect the relative expression of GSK-3ß, ß-catenin, E-cadherin, N-cadherin, and Vimentin proteins in the endometrial tissue. Another 5 rats from each group were placed in cages with male rats after intervention to record the number of embryo implantations. RESULTS: Necrosis and loss of endometrial tissue in the model group observed after HE staining were alleviated in the EA group, better than those in the ICG-001 group. Compared with the blank group, the numbers of glands and endometrial thickness in the uterine endometrial tissue, relative expression and positive expression of E-cadherin and GSK-3ß proteins in the uterine endometrial tissue, and embryo implantation numbers were reduced(P<0.000 1, P<0.001, P<0.01) in the model group, while fibrosis area ratio in the uterine endometrial tissue, TGF- ß 1, α -SMA, FN, CTGF, Col- â positive expressions, N-cadherin, Vimentin, and ß-catenin proteins expression and positive expression were increased(P<0.000 1, P<0.001, P<0.01). Compared with the model group, the number of glands and endometrial thickness, E-cadherin and GSK-3ß proteins expression and positive expression, and embryo implantation numbers were increased (P<0.001, P<0.05, P<0.01) in the EA and ICG-001 groups, while the fibrosis area ratio in the uterine endometrial tissue, TGF-ß1, α-SMA, FN, CTGF, Col- â positive expression, and N-cadherin, Vimentin, and ß-catenin proteins expression and positive expression were decreased(P<0.001, P<0.01, P<0.05). Compared with the EA group, the differences of the above-mentioned indicators in the ICG-001 group were not statistically significant. CONCLUSIONS: EA may reverse the EMT process and reduce the degree of fibrosis in endometrial tissue by inhibiting the Wnt/ß-catenin signaling pathway, thereby promoting the repair of endometrial damage in IUA.
