OBJECTIVE
The study aimed to examine the clinical profile, surgical management, and outcomes of patients admitted for ectopic pregnancy.
A five-year retrospective study of ectopic pregnancies admitted in a tertiary training hospital in the Philippines was performed. Data from admission and operating room records were used to obtain the annual cumulative incidence of ectopic pregnancy. Subjects were divided into laparotomy versus laparoscopy groups, and salpingostomy versus salpingectomy groups; differences in the means/medians/mean-ranks and proportions of the different clinical and outcome variables of interest were compared by Student t test/Mann-Whitney U test and chisquare/Fisher exact test of homogeneity, respectively.
RESULTSThe cumulative incidence of ectopic pregnancy ranged from 2.30% to 4.01% from 2017 to 2021. A total of 128 patients were included in the final analysis with a mean age of 27.8 ± 5.73 years. The most common identified risk factors were smoking (17.97%), previous ectopic pregnancy (17.19%), and previous tubal surgery (15.62%). The ampulla was the most common site of tubal involvement. Of the 128 patients, 45.31% underwent laparotomy while 54.69% underwent laparoscopy. Salpingectomy was performed in 76.56% of patients. Tubal rupture was noted in 42.97% of cases. Patients with abdominal pain, back pain, shoulder pain, and dizziness were more likely to undergo laparotomy than laparoscopy (p < 0.05). A lower β-hCG value was noted in patients who underwent salpingostomy compared to salpingectomy (5,569.80 mIU/mL vs 10,555.47, p < 0.05). Salpingostomy was more likely to be performed on patients with previous ectopic pregnancy (p < 0.05) and previous tubal surgery (p < 0.05) than salpingectomy.
CONCLUSIONThe cumulative incidence of ectopic pregnancy in our institution was higher than global estimates. Risk factors and anatomic site of tubal involvement were similar to those reported in literature. Laparoscopy seemed to be underutilized for cases of ruptured ectopic pregnancy. Training on minimally invasive procedures should be provided to point-ofcare trainees or residents for patients to be afforded the benefits of laparoscopy.

Caesarean scar pregnancy (CSP) is a pregnancy where embryo is implanted in the myometrium of a previous caesarean scar and it is a rare type of ectopic pregnancy. Diagnosis and management of CSP is a challenge because caregivers lack awareness about the possibility of implantation in previous caesarean surgery scar. We present here six CSP cases. All patients presented with abdominal pain and/or bleeding per vaginum with history of previous caesarean section. On ultrasonography, caesarean scar pregnancy was diagnosed. We managed them endoscopically at an endoscopic surgery and training center during the year 2019 till the year 2022. The pre-operative and post-operative periods were uneventful and they were discharged on day 2 or 3 of surgery. Hystero-laparoscopic combined approach is a good option for managing CSP in expert hands. Although there are no clear guidelines for managing CSP, we suggest individualizing each patient's treatment plan, depending on their personal characteristics and available facilities at the managing center.

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.

Introduction:
Steroid cell tumors are rare sex cord-stromal tumors,
accounting for <0.1% of ovarian neoplasms. Extraovarian
steroid cell tumors are exceptionally rare, often androgensecreting, and pose significant diagnostic challenges. Early
recognition is essential to prevent prolonged morbidity
from hyperandrogenism.
Case:
A 60-year-old female, 15 years after total hysterectomy
and bilateral salpingo-oophorectomy for a large ovarian
mass with massive ascites, presented with deranged liver
function tests on routine follow-up. Ultrasonography
and computed tomography imaging revealed multiple
hypervascular lesions in the liver, retroperitoneum,
and peritoneum, suggestive of metastatic disease, with
normal-appearing adrenal glands. Biopsy of a liver lesion
demonstrated a metastatic neoplasm with morphology and
immunoprofile favoring a steroid cell tumor. However,
metastasis from the adrenal cortex or an ovarian primary
could not be excluded.
Given the prior bilateral oophorectomy, metastatic adrenocortical carcinoma was initially suspected, prompting
endocrine evaluation. Further history revealed a 1-year
history of progressive virilization, including increased
facial hair and frontal balding. Hormonal studies
demonstrated elevated testosterone (12.2 mmol/L and
reference range 0.1–1.42) and dehydroepiandrosterone
sulfate (15.9 µmol/L and reference range 0.510–5.560)
and the adrenocorticotropic hormone level of 11.7
pmol/L (reference range 1.60–13.9) with suppressed
gonadotrophins. Additional workup for catecholamine,
cortisol, and aldosterone excess was unremarkable. The discordance between androgen excess and normal adrenal
imaging, despite absent ovarian tissue, suggested an extraadrenal androgen-secreting steroid cell tumor. A second
histopathology review and multidisciplinary discussion
with radiology, gynecologic oncology, and pathology teams
were undertaken. As the disease was deemed inoperable,
repeat retroperitoneal lesion biopsy confirmed metastatic
steroid cell tumor and guided palliative chemotherapy.
She was subsequently referred to gynecologic oncology
for systemic chemotherapy.
Conclusion
Extra-adrenal steroid cell tumors, though rare, should be
considered in patients with hyperandrogenism long after
bilateral oophorectomy, especially when adrenal imaging
is normal. Multidisciplinary evaluation and repeat biopsy
are often crucial for establishing the diagnosis and guiding
treatment.

OBJECTIVE:
To investigate the effect of human adipose-derived mesenchymal stem cells (hASCs) exosomes on osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) extracted from osteoporotic mice, and to evaluate the effect of hASCs exosomes on preventing bone loss induced by estrogen deficiency.
METHODS:
hASCs exosomes were extracted by ultracentrifugation. The osteoporotic mice were established by bilateral ovariectomy (OVX). BMSCs were isolated from osteo-porotic mice and cultured for further analysis. In the experimental group, these BMSCs were exposed to an osteogenic induction medium supplemented with hASCs exosomes to evaluate their potential effects on osteogenesis. In contrast, the control group was treated with the same osteogenic induction medium, but without the addition of hASCs exosomes, to serve as a baseline comparison for the study. To comprehensively assess the osteogenic differentiation of BMSCs influenced by hASCs exosomes, alkaline phosphatase (ALP) staining, ALP activity quantitative analysis and quantitative reverse transcription polymerase chain reaction (qPCR) were performed. These evaluations provided critical insights into the role of hASCs exosomes in promoting osteoblast differentiation and bone formation in osteoporotic conditions. The fluorescence labeled hASCs exosomes were injected via the tail vein to observe the biodistribution of exosomes. Two weeks after OVX, the mice were divided into three groups: The experimental group consisted of estrogen-deficient mice receiving hASCs exosome injections; the negative control group consisted of estrogen-deficient mice receiving phosphate-buffered saline (PBS) injections; and the positive control group consisted of mice that underwent Sham surgery and received PBS injections.The injections were administered once every 3 days, for a total of 8 injections. Afterward, the femurs were collected from the mice, and micro-computed tomography (micro-CT) was performed to measure bone mineral density and conduct bone morphometric analysis.
RESULTS:
hASCs exosomes were successfully extracted using ultracentrifugation. After the induction by hASCs exosomes, ALP staining and ALP activity in the BMSCs extracted from osteoporotic mice were significantly enhanced, the expression of osteogenesis related genes in BMSCs were significantly up-regulated. More trabecular bone and higher bone mineral density were observed in estrogen-deficient mice injected with hASCs exosomes compared with estrogen-deficient mice injected with PBS, and there was no significant decrease in bone mineral density compared with the Sham operation group.
CONCLUSION
hASCs exosomes promoted the osteogenic differentiation of BMSCs extracted from osteoporotic mice. hASCs exosomes prevented bone loss induced by estrogen deficiency.

OBJECTIVE:
To investigate the Wnt signaling pathway and miRNAs mechanism of extracts of Plastrum Testudinis (PT) in the treatment of osteoporosis (OP).
METHODS:
Thirty female Sprague Dawley rats were randomly divided into 5 groups by random number table method, including sham group, ovariectomized group (OVX), ovariectomized groups treated with high-, medium-, and low-dose PT (160, 80, 40 mg/kg per day, respectively), with 6 rats in each group. Except for the sham group, the other rats underwent bilateral ovariectomy to simulate OP and received PT by oral gavage for 10 consecutive weeks. After treatment, bone mineral density was measured by dual-energy X-ray absorptiometry; bone microstructure was analyzed by micro-computed tomography and hematoxylin and eosin staining; and the expressions of osteogenic differentiation-related factors were detected by immunochemistry, Western blot, and quantitative polymerase chain reaction. In addition, Dickkopf-1 (Dkk-1) was used to inhibit the Wnt signaling pathway in bone marrow mesenchymal stem cells (BMSCs) and miRNA overexpression was used to evaluate the effect of miR-214 on the osteogenic differentiation of BMSCs. Subsequently, PT extract was used to rescue the effects of Dkk-1 and miR-214, and its impacts on the osteogenic differentiation-related factors of BMSCs were evaluated.
RESULTS:
PT-M and PT-L significantly reduced the weight gain in OVX rats (P<0.05). PT also regulated the bone mass and bone microarchitecture of the femur in OVX rats, and increased the expressions of bone formation-related factors including alkaline phosphatase, bone morphogenetic protein type 2, collagen type I alpha 1, and runt-related transcription factor 2 when compared with the OVX group (P<0.05 or P<0.01). Meanwhile, different doses of PT significantly rescued the inhibition of Wnt signaling pathway-related factors in OVX rats, and increased the mRNA or protein expressions of Wnt3a, β-catenin, glycogen synthase kinase-3β, and low-density lipoprotein receptor-related protein 5 (P<0.05 or P<0.01). PT stimulated the osteogenic differentiation of BMSCs inhibited by Dkk-1 and activated the Wnt signaling pathway. In addition, the expression of miR-214 was decreased in OVX rats (P<0.01), and it was negatively correlated with the osteogenic differentiation of BMSCs (P<0.01). MiR-214 mimic inhibited Wnt signaling pathway in BMSCs (P<0.05 or P<0.01). Conversely, PT effectively counteracted the effect of miR-214 mimic, thereby activating the Wnt signaling pathway and stimulating osteogenic differentiation in BMSCs (P<0.05 or P<0.01).
CONCLUSION
PT stimulates bone formation in OVX rats through β-catenin-mediated Wnt signaling pathway, which may be related to inhibiting miR-214 in BMSCs.

Journal of Central South University(Medical Sciences) 2025;50(1):52-60
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.

Retained products of conception (RPOC) represent a common pregnancy-related condition that may lead to complications such as abnormal uterine bleeding, infection, secondary arteriovenous fistula, intrauterine adhesions, and infertility. Currently, the main clinical treatments for RPOC include surgical intervention, medical therapy, and expectant management, sometimes supplemented by high-intensity focused ultrasound or uterine artery embolization when necessary. However, no standardized treatment guidelines exist. Medical and expectant management may help some patients avoid or reduce the need for surgery, though these approaches often involve a prolonged disease course. While surgery yields rapid results, patients with large lesions may require multiple procedures, increasing the risk of endometrial damage and intrauterine adhesions. There is still a lack of robust evidence-based guidance for selecting the optimal or individualized treatment approach. This review explores recent advances in the management of RPOC, with an emphasis on strategies that effectively preserve the endometrium, safeguard fertility, and support more precise, minimally invasive, and efficient personalized treatment.

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.

Journal of Central South University(Medical Sciences) 2025;50(7):1126-1136
OBJECTIVES:
The core pathology of osteoporosis lies in bone resorption exceeding bone formation; thus, promoting osteogenesis is a key therapeutic strategy. The osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) forms the biological basis of bone formation. Astragaloside IV (A-IV), a major active component of Astragalus membranaceus, is known to enhance osteogenesis, but its precise molecular mechanisms remain unclear. This study aims to investigate the effects of A-IV on the proliferation and osteogenic differentiation of BMSCs from osteoporotic rats and to elucidate its molecular mechanism through the regulation of microRNA-21 (miR-21) and Notch2 expression.
METHODS:
After 1 week of adaptive feeding, mature female SD rats were randomly divided into a sham-operated (Sham) group (n=4) and an ovariectomized (OVX) group (n=8) to establish an osteoporosis model. Twelve weeks after surgery, BMSCs were isolated from femoral bone marrow and cultured. Cells were divided into a S-BMSCs group (from Sham), an O-BMSCs group (from OVX), and an A-BMSCs group (from OVX-derived BMSCs treated with A-IV). S-BMSCs and O-BMSCs were induced for osteogenic differentiation using osteogenic induction medium, whereas A-BMSCs were treated with A-IV before induction. Flow cytometry was used to identify mesenchymal stem cell surface markers (CD29) and hematopoietic stem cell marker (CD34) to confirm BMSC characteristics. Cell proliferation was assessed using the methyl thiazolyl tetrazolium (MTT) assay. Alizarin red staining was performed to quantify calcium nodule formation, and alkaline phosphatase (ALP) activity assays were used to evaluate osteogenic differentiation. Real-time reverse transcription PCR (real-time RT-PCR) was used to detect changes in osteogenic-related genes, runt-related transcription factor 2 (Runx2) and osteopontin (OPN), as well as miR-21 expression. Western blotting was performed to assess Runx2, OPN, and Notch2 protein expression.
RESULTS:
Flow cytometry confirmed that O-BMSCs retained the phenotypic characteristics of mesenchymal stem cells. A-IV significantly enhanced the proliferation of BMSCs from osteoporotic rats (P<0.05), increased ALP activity, and upregulated the mRNA and protein expression of Runx2 and OPN (P<0.05). Bioinformatic and experimental analyses demonstrated that miR-21 directly targeted Notch2. A-IV treatment increased miR-21 expression while suppressing Notch2 protein expression and inhibiting activation of the Notch signaling pathway (P<0.05).
CONCLUSIONS
Astragaloside IV promotes the osteogenic differentiation of BMSCs derived from osteoporotic rats by upregulating miR-21 expression and inhibiting the key Notch signaling protein Notch2, thereby relieving the Notch2-mediated suppression of osteogenesis.
