A unicornuate uterus with a non-communicating rudimentary horn is a rare Müllerian duct anomaly that is frequently underdiagnosed because of its variable clinical presentation and the limitations of conventional imaging modalities. Although not considered a direct cause of infertility, it may coexist with other reproductive pathologies and contribute to adverse reproductive outcomes. Presented here is a case series of three infertile women aged 30–36 years who were diagnosed with a unicornuate uterus and non-communicating rudimentary horn during fertility evaluation. Patient A presented with primary infertility, cyclic pelvic pain, endometriosis, and bilateral tubal disease; Patient B had a seven-year history of primary infertility and was initially suspected to have unilateral tubal obstruction; and Patient C was referred with a presumed diagnosis of uterine didelphys and was subsequently found to have a unicornuate uterus with a non-communicating rudimentary horn and ipsilateral renal agenesis. In all three cases, preoperative imaging failed to establish the definitive diagnosis, which was confirmed intraoperatively through laparoscopy, chromotubation, and hysteroscopy. Patients A and B underwent laparoscopic excision of the rudimentary horn with ipsilateral salpingectomy, while Patient C underwent only ipsilateral salpingectomy. Hysteroscopic transillumination was utilized in one case to facilitate safe laparoscopic dissection and delineation of the hemiuterine anatomy. All patients had uneventful postoperative recovery and were subsequently counseled regarding fertility options. This case series highlights the diagnostic challenges posed by unicornuate uterus with a non-communicating rudimentary horn, emphasizes the importance of a high index of suspicion during infertility work-up, and demonstrates the value of minimally invasive surgical management and hysteroscopic transillumination in selected cases. Early recognition and individualized treatment may help reduce reproductive complications and improve fertility counseling and management.

BACKGROUND: Hyperthermia (HT), while a cancer treatment approach, isn't always effective alone. Therefore, identifying hyperthermia enhancers is crucial. We demonstrated that Mito-TEMPO ([2-[(1-Hydroxy-2,2,6,6-tetramethylpiperidin-4-yl) amino]-2-oxoethyl]-triphenylphosphanium, MT) acts as a potent thermosensitizer, promoting cell death in human cervical cancer (HeLa) cells. METHODS: Cells were pretreated with 0.4 mM MT for 5 minutes, followed by exposure to hyperthermia (42 °C for 60 minutes). The impacts of MT/HT on cell viability, proliferation, apoptosis, endoplasmic reticulum (ER) stress, apoptosis-related proteins and autophagy, autophagy-related proteins expression were measured. The relationships between autophagy and apoptosis were further investigated using the specific autophagy inhibitor chloroquine (CQ) and the autophagy inducer rapamycin (Rapa). RESULTS: The combined treatment reduced the mitochondrial membrane potential (MMP) and increased ROS production. It also upregulated the pro-apoptotic protein Bax and downregulated anti-apoptotic proteins such as Bcl-2 and MCL-1. As a result, Caspase-3 was activated. Additionally, the combined treatment upregulated the expression of p-PERK/PERK, ATF-4, CHOP proteins. Moreover, the combined treatment also increased the expression of LC3 II and p62, decreased expression of LAMP 1 and Cathepsin D and increased lysosomal pH, indicating coordinated changes in autophagy regulation. Notably, intensification of apoptosis induced by the combined treatment was observed with CQ, whereas attenuation was seen with Rapa. CONCLUSIONS MT effectively enhanced HT-induced apoptosis in HeLa cells. Elevated ER stress and interruption of autophagy flux are the possible underlying molecular mechanisms for this phenomenon. These findings suggested MT can act as a potential thermosensitizer, highlighting its versatility in cancer treatment strategies.

OBJECTIVES: Endometrial tuberculosis, which commonly affects women of reproductive age, is a significant cause of intrauterine adhesions (IUA), potentially leading to hypomenorrhea, amenorrhea, and infertility. Hysteroscopic adhesiolysis is the primary treatment for IUA; however, studies specifically addressing its efficacy in tuberculosis-induced IUA remain scarce. This study aims to evaluate the therapeutic outcomes of hysteroscopic adhesiolysis for IUA caused by endometrial tuberculosis. METHODS: This retrospective cohort study included patients diagnosed with tuberculosis-induced IUA who underwent hysteroscopic adhesiolysis at the Third Xiangya Hospital of Central South University between May 2014 and October 2022. Clinical data including age, medical history, adhesion severity, surgical treatment, and reproductive outcomes were analyzed. RESULTS: Among 39 patients identified, 2 were lost to follow-up. A total of 37 patients were included, with a follow-up duration ranging from 6 months to 9 years. Hypomenorrhea was reported in 24 (64.9%) patients, secondary amenorrhea in 10 (27.0%) patients, and normal menstruation in 3 (8.1%) patients. Most patients presented with primary infertility (59.5%), and only 2 (5.4%) had secondary infertility. The median American Fertility Society (AFS) score at initial assessment was 10 (range, 8-12); 8 (21.6%) patients had moderate IUA, and 29 (78.4%) had severe IUA. A total of 86 surgical procedures were performed across 37 patients, with 27 patients undergoing 2 or more surgeries. Postoperatively, 25 (67.6%) patients achieved normalization of the uterine cavity, while 12 (32.4%) still had a reduced cavity. Only 7 (18.9%) patients had a grossly normal endometrium at the final surgery, all of whom had moderate adhesions at the initial procedure. Menstrual flow returned to normal in 12 (32.4%) patients, while 25 (67.6%) continued to experience hypomenorrhea. Of 29 patients who attempted in vitro fertilization and embryo transfer (IVF-ET), only 6 (20.7%) conceived. Among these, 4 (13.8%) delivered at term via cesarean section; one case was complicated by postpartum hemorrhage due to uterine atony and another by placental adhesion. CONCLUSIONS Endometrial tuberculosis can lead to severe IUA. Hysteroscopic adhesiolysis facilitates cavity restoration and improvement of menstrual conditions, but the overall reproductive outcomes remain suboptimal.

Atypical placental site nodules (APSN) are a rare form of trophoblastic disease in pregnancy. There is limited research on APSN, and treatment methods are controversial, with unclear prognosis. This study collected clinical and prognostic data of 5 patients diagnosed with APSN at Xiangya Hospital of Central South University from June 2008 to June 2023, aiming to provide a better understanding of the prognosis of APSN patients and offer scientific evidence for clinical treatment. The average age of the 5 APSN patients was 32.60 years, and all patients underwent dilation and curettage or hysteroscopic surgery or hysteroscopic surgery without hysterectomy. Except for one patient who was lost to follow-up after 30 days, the remaining 4 patients were followed up for 1.36 to 4.61 years. During the follow-up, gynecological ultrasound did not show abnormalities, and serum human chorionic gonadotropin (HCG) tests were negative, with no evidence of malignancy. A search of both English and Chinese databases yielded 8 articles reporting the diagnosis, treatment, and follow-up outcomes of APSN, with 37 cases cumulatively followed up. Among them, 2 (5.41%) cases developed epithelial trophoblastic tumors or placental site trophoblastic tumors during follow-up, but there is insufficient evidence to determine whether these tumors directly originated from APSN or were secondary to APSN. Currently, there is no direct evidence suggesting that APSN has the potential for malignant transformation. Patients with APSN who have completed their childbearing may consider preserving their uterus, but close follow-up is needed to further evaluate the prognosis.

OBJECTIVES: Transcervical resection of adhesions (TCRA) under hysteroscopy is the mainstay treatment for intrauterine adhesions (IUA), but its effectiveness varies depending on the surgical approach. This study aims to investigate the impact of different surgical techniques on endometrial repair and pregnancy outcomes in patients with secondary infertility and moderate-to-severe IUA. METHODS: A retrospective analysis was conducted on 225 patients who underwent TCRA followed by in vitro fertilization and embryo transfer between January 2021 and December 2022. Patients were grouped based on the surgical method: A cold knife group (n=127) and an electrosurgical group (n=98). Adhesions were separated using either cold knife or electrosurgical instruments. Postoperative visualization of uterine angle and tubal ostia, endometrial restoration, vascular endothelial growth factor (VEGF) expression in adhesion tissues, and clinical pregnancy outcomes were compared. Univariate and multivariate Logistic regression analyses were performed to identify factors influencing pregnancy outcomes. A LightGBM model was constructed to predict pregnancy outcomes. RESULTS: Compared with the electrosurgical group, patients in the cold knife group had significantly greater postoperative endometrial thickness [(8.86±0.53) mm vs (8.10±0.87) mm, P<0.05], higher live birth rates (64.57% vs 30.61%, P<0.05), and lower VEGF expression (1.31±0.09 vs 1.53±0.16, P<0.05). Logistic regression analyses identified age, number of visible tubal ostia postoperatively, and surgical method as significant factors affecting pregnancy outcomes (P<0.05). The LightGBM model based on surgical method had an area under the curve (AUC) of 0.882 (0.838-0.926), with internal validation AUC of 0.817 (0.790-0.840). CONCLUSIONS Cold knife surgery promotes faster recovery of the endometrial microenvironment and earlier improvement of fertility in patients with secondary infertility and IUA Surgical method is a key factor influencing pregnancy outcomes, and the LightGBM model based on surgical approach shows good predictive performance for pregnancy outcomes in patients with moderate-to-severe IUA.

OBJECTIVES: Hysterectomy remains the only definitively effective treatment for diffuse uterine leiomyomatosis (DUL). However, no standardized management strategy exists for DUL patients wishing to preserve fertility. This study summarizes and analyzes 5 cases of individualized treatment in DUL patients desiring fertility preservation, aiming to provide a clinical reference for personalized management of similar patients. METHODS: We retrospectively analyzed the clinical data of 5 DUL patients with fertility intentions admitted to the Department of Obstetrics and Gynecology at Third Xiangya Hospital of Central South University. To preserve fertility, individualized treatment plans were selected based on clinical manifestations and fibroid distribution. One patient received high-intensity focused ultrasound (HIFU); one underwent hysteroscopic myomectomy (HM) combined with laparoscopic myomectomy (LRM); one underwent HIFU combined with HM and LRM; one received drug therapy combined with staged HM; and one underwent HIFU combined with staged HM and drug therapy. Treatment outcomes and pregnancy results were analyzed. RESULTS: After treatment, all 5 patients showed marked improvement in menstrual volume or dysmenorrhea symptoms and significant reduction in uterine volume; mild intrauterine adhesions occurred in 3 cases. All 5 patients achieved successful pregnancy. One patient with chronic hypertension developed severe preeclampsia at 34 weeks and underwent cesarean section, while the remaining 4 delivered at term by cesarean section. Three cases of placenta accreta and 2 cases of postpartum hemorrhage occurred. During long-term follow-up, one patient underwent hysterectomy 2 years postpartum due to increased menstrual volume, while the other 4 remained stable. CONCLUSIONS Individualized treatment tailored to DUL patients' conditions can preserve fertility, support successful pregnancy, and achieve favorable pregnancy outcomes.

OBJECTIVES: To investigate the regulatory effects of Aurora-A in regulating proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of cervical cancer cells and the role of actin-related protein 2/3 complex subunit 4 (ARPC4) in mediating its effects. METHODS: The plasmids pCDH-NC, pCDH-Aurora-A, and shRNA-ARPC4 were used for inducing Aurora-A overexpression or ARPC4 knockdown in HeLa cells. The cells were divided into vector group, Aurora-A overexpression group, Aurora-A overexpression+ARPC4 knockdown group, and Aurora-A overexpression+NF‑κBp65 inhibitor group and transfected with the corresponding plasmids. The proliferation, colony-forming ability, migration and invasion of the treated Hela cells was evaluated using EdU immunofluorescence assay, crystal violet staining, scratch assay, Transwell assay, and Matrigel assay. Western blotting was performed to detect the changes in cellular expressions of EMT-related proteins and expression levels of NF-κBp65 and ARPC4. RESULTS: The expression of ARPC4 was significantly decreased in HeLa cells with Aurora-A knockdown and increased in Aurora-A-overexpressing cells. Aurora-A overexpression obviously promoted proliferation, migration, and invasion abilities of HeLa cells, and these effects was significantly antagonized by ARPC4 knockdown. In Aurora-A-overexpressing cells, the phosphorylation level of NF-κBp65 and the expression level of ARPC4 were increased significantly, and application of the NF‑κBp65 inhibitor obviously lowered the expression level of ARPC4. CONCLUSIONS Aurora-A overexpression upregulates the expression of ARPC4 by activating the NF-κBp65 signaling pathway, thereby promoting migration, invasion and EMT of HeLa cells.

OBJECTIVES: To study the effect of CDC20 knockdown on proliferation, migration and invasion of cervical cancer cells and its underlying mechanism. METHODS: CDC20 expression in cervical cancer tissues was analyzed using the TCGA database, and the protein expressions of CDC20 and β-Catenin in clinical specimens of cervical cancer and adjacent tissues were detected using immunohistochemistry. A dual target sgRNA2&7 sequence for CDC20 gene was designed for CDC20 gene knockdown in cervical cancer C33A cells using CRISPR/Cas9 technology, and CDC20 mRNA and protein expression levels in the transfected cells were detected using qRT-PCR and Western blotting. The changes in proliferation, cell cycle, apoptosis, migration and invasiveness of the transfected cells were evaluated using colony-forming assay, fluorescence activated cell sorting (FACS) and Transwell assay. In the animal experiment, naïve C33A cells and the cells with CDC20 knockdown were injected subcutaneously into the left and right axillae of nude mice (n=5) to observe tumor growth. The expressions of CDC20 and β-Catenin proteins in transfected cells and the xenograft were analyzed using Western blotting, and their interaction was confirmed by co-immunoprecipitation (CoIP) and immunofluorescence co-localization assays. RESULTS: Cervical cancer tissues expressed significantly higher CDC20 and β‑Catenin levels than the adjacent tissues. C33A cells with CDC20 knockdown showed reduced proliferation, increased apoptosis, and lowered migration and invasion abilities. CDC20 knockdown significantly suppressed the growth of C33A cell xenograft in nude mice, and the tumor-bearing mice did not exhibit obvious body mass changes. CDC20 and β-Catenin levels were both significantly lowered in C33A cells with CDC20 knockdown. Co-immunoprecipitation and co-localization assays confirmed the interaction between CDC20 and β‑Catenin. CONCLUSIONS CDC20 is highly expressed in cervical cancer tissues, and CDC20 knockdown can suppress proliferation, invasion, and metastasis while enhancing apoptosis of C33A cells, which is closely related with the regulation of the Wnt/β-Catenin signaling pathway.

OBJECTIVES: To explore the therapeutic mechanism of Guizhi Fuling (GZFL) Pellets against cervical cancer. METHODS: Publicly available databases were used to identify the targets of GZFL Pellets and cervical cancer to construct the protein-protein interaction (PPI) network, followed by GO biological process and KEGG pathway enrichment analysis of the hub genes. The "Traditional Chinese Medicine-Active Ingredients-Targets-Pathways" network for GZFL Pellets in cervical cancer treatment was generated using Cytoscape v10.0.0, and molecular docking of the drug and potential targets was performed to predict the specific targets of active components in Guizhi Fuling Pellets. The inhibitory effects of hederagenin, an active ingredient in GZFL Pellets, was tested in cultured cervical cancer cells and in nude mice bearing cervical cancer xenografts. RESULTS: GZFL Pellets contain 338 active components targeting 247 action sites. A total of 10127 cervical cancer-related targets were obtained, and among them 195 were identified as potential therapeutic targets of GZFL Pellets for cervical cancer treatment, including the key targets of GABRA1, PTK2, JAK2, HTR3A, GSR, and IL-17. Molecular docking study showed low binding energies of the active components such as hederagenin, campesterol, and stigmasterol for protein-molecule interaction. GO enrichment analysis suggested that GZFL Pellets inhibited cervical cancer primarily by regulating responses to steroid hormones, oxidative stress, and lipopolysaccharides. Among the active components of GZFL Pellets, hederagenin was found to inhibit cervical cancer cells in vitro and significantly reduced STAT3 phosphorylation level in the cancer cells. In nude mice bearing cervical cancer xenografts, hederagenin effectively inhibited tumor growth rate without causing obvious adverse effects. CONCLUSIONS GZFL Pellets inhibit cervical cancer cell growth through its multiple active components that target different pathways. Among these components, hederagenin inhibits tumor cell growth possibly by directly binding to JAK2 protein to inhibit STAT3 phosphorylation.
