OBJECTIVES: Stress urinary incontinence (SUI) is a common condition among women that severely impairs quality of life. Pelvic floor proprioceptive training (PFPT) has attracted increasing attention for its potential to enhance pelvic floor muscle function and alleviate SUI symptoms. This study aims to observe and compare the clinical efficacy of PFPT combined with electroacupuncture, electrical stimulation, and biofeedback therapy versus conventional therapy consisting of electroacupuncture, electrical stimulation, and biofeedback alone in women with SUI, and to explore the role of PFPT in improving symptom and functional outcomes. METHODS: In this randomized controlled trial, 72 women with mild to moderate SUI were recruited from the Department of Rehabilitation Medicine at Third Xiangya Hospital, Central South University, between December 2021 and October 2023. Participants were randomly assigned to an experimental group (n=36) or a control group (n=36). Both groups received health education. The control group underwent electroacupuncture combined with electrical stimulation and biofeedback therapy, while the experimental group additionally received PFPT 3 times per week for 4 weeks. The primary outcome was assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Secondary outcomes included pelvic floor muscle strength, bladder neck mobility, and balance ability. The ICIQ-SF was reassessed at 1, 3, 6, and 12 months post-treatment. RESULTS: Both groups showed statistically significant improvements in all parameters after treatment (all P<0.05). However, there were no statistically significant differences between groups in most measures (all P>0.05). The experimental group demonstrated longer single-leg stance duration with eyes closed than the control group (left leg: P=0.026; right leg: P=0.006), with a significant increase from baseline (P<0.001). At 6 months post-treatment, the cure rate in the experimental group was significantly higher than that in the control group (P=0.037). CONCLUSIONS Conventional therapy effectively improves SUI symptoms, but adding PFPT provides notable additional benefits, including enhanced balance ability and sustained mid-term cure rates. These findings suggest that PFPT is a valuable adjunct to standard SUI management strategies.

Objective:To investigate the therapeutic efficacy of programmed death-1(PD-1)inhibitors in combination with drug-eluting beads transcatheter arterial chemoembolization(DEB-TACE)and radiofrequency ablation(RFA), as well as their impact on the prognosis of older patients with primary hepatocellular carcinoma(HCC).Methods:In this prospective cohort study, 120 patients aged 65 years and older with HCC at stage Ⅱb-Ⅲb were randomly assigned to an observation group (n=60)and a control group (n=60)between January 2021 and January 2024.The control group received DEB-TACE followed by RFA, while the observation group received a PD-1 inhibitor in combination with DEB-TACE followed by RFA, with both interventions lasting for 12 weeks.The clinical efficacy of the treatments in both groups was assessed, and changes in serum tumor markers before and after treatment were compared between the two groups.Safety was evaluated, survival data were recorded during follow-up, and the effects of different therapeutic regimens on patient prognosis were analyzed.Results:The disease control rate(DCR)and objective response rate(ORR)in the observation group were 88.33% and 78.33%, respectively, which were higher than those in the control group (71.67% and 28.33%, χ2=5.208, 30.134, P=0.022, <0.001). After treatment, levels of serum tumor markers (alpha fetoprotein, carbohydrate antigen 125, vascular endothelial growth factor)decreased in both groups (all P<0.05), with levels in the observation group being lower than those in the control group (all P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (all P>0.05). By the end of follow-up, which ranged from 2 to 33 months, there were 15 death cases in the observation group, resulting in a cumulative survival rate of 75.00%(45/60) and a mean survival of 25.95 months.In the control group, there were 25 death cases, with a cumulative survival rate of 58.33%(35/60)and a mean survival of 20.33 months.The results of the Kaplan-Meier function analysis were as follows: Log-rank χ2=5.747, P=0.017; Breslow χ2=3.124, P=0.077.The results of the multivariate Cox regression analysis indicated that PD-1 inhibitor combined with DEB-TACE sequential RFA was a protective factor against death in older patients with primary HCC( HR=0.680, 95% CI: 0.463-0.998, P=0.014). Conclusions:The curative effect and safety of PD-1 inhibitor combined with DEB-TACE and RFA are favorable in older patients with advanced HCC.

OBJECTIVES: Pelvic organ prolapse (POP) is a common condition in postmenopausal women, with an increasing prevalence due to aging. Some women experience POP recurrence after surgical treatment, significantly affecting their physical and mental health. The uterosacral ligament is a critical pelvic support structure. This study aims to investigate the molecular pathological changes in the uterosacral ligament of postmenopausal women with recurrent POP using transcriptomic analysis. METHODS: Transcriptomic data of uterosacral ligament tissues were obtained from the public dataset GSE28660, which includes samples from 4 postmenopausal women with recurrent POP, 4 with primary POP, and 4 without POP. Differentially expressed genes (DEGs) were identified between recurrent POP and both primary and non-POP groups. Further analysis included intersection analysis of DEGs, gene ontology enrichment, protein-protein interaction (PPI) network construction, gene set enrichment analysis (GSEA), single-sample GSEA, and xCell immune cell infiltration analysis to explore molecular pathological changes in recurrent POP. Additionally, histological and molecular differences in the uterosacral ligament were compared between simulated vaginal delivery (SVD) rat models with and without ovariectomy. RESULTS: Compared with primary POP and non-POP groups, recurrent POP exhibited activation of adipogenesis and inflammation-related pathways, while pathways related to muscle proliferation and contraction were downregulated in the uterosacral ligament. Nine key DEGs (ADIPOQ, FABP4, IL-6, LIPE, LPL, PCK1, PLIN1, PPARG, and CD36) were identified, with most enriched in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. These genes were significantly correlated with lipid accumulation, monocyte infiltration, and neutrophil infiltration in the uterosacral ligament. Urodynamic testing revealed that the bladder leak point pressure was significantly higher in ovariectomized SVD rats, both of which had higher values than the sham group. Masson staining showed pronounced adipogenesis in the uterosacral ligament of ovariectomized SVD rats, along with reduced collagen and muscle fibers compared to the sham and non-ovariectomized SVD groups. Furthermore, real-time RT-PCR confirmed significantly elevated expression of key DEGs, including ADIPOQ, IL-6, PCK1, and PLIN1, in the uterosacral ligaments of ovariectomized SVD rats. CONCLUSIONS Adipogenesis and inflammation in the uterosacral ligament may contribute to its reduced supportive function, potentially leading to recurrence POP in postmenopausal women.

OBJECTIVES: Pelvic floor sensory training is commonly used in clinical practice for the treatment of stress urinary incontinence (SUI); however, there is a lack of comparative studies evaluating pelvic floor sensation between women with SUI and healthy controls. Additionally, normative data for two-point discrimination thresholds in the female pelvic floor region remain scarce. This study aims to compare the results of 4 sensory tests in the pelvic floor region between women with mild SUI and healthy women, in order to provide reference values for two-point discrimination thresholds in this area. METHODS: From April 1 to October 30, 2023, 108 healthy women [(32.5±3.6) years] and 90 women with mild SUI [(32.9±3.3) years] were recruited from the Third Xiangya Hospital, Central South University. Participants underwent 4 sensory tests in the pelvic floor region: Two-dot discrimination, weight perception, shape recognition, and 9-grid localization. The results were compared between the 2 groups. RESULTS: Compared with healthy women, those with mild SUI had lower sensitivity and higher thresholds in 2-dot discrimination tests in the pelvic floor region (all P<0.001). No significant differences were found between groups in weight perception, shape recognition, or grid localization tests (P>0.05). CONCLUSIONS Women with mild stress urinary incontinence have impaired two-point discrimination ability in the pelvic floor region.

Objective:To investigate the clinicopathological features, immunophenotype, molecular characteristics, and differential diagnosis of primary intracranial DICER1-mutant sarcoma in order to better understand this tumor type.Methods:A retrospective analysis was conducted on 7 cases of primary intracranial DICER1-mutant sarcoma diagnosed in the Department of Pathology, Sun Yat-sen University Cancer Center, Guangzhou, China between 2021 and 2023 using next-generation sequencing. At the same time, 10 gliosarcomas, 4 intracranial FET::CREB fusion-positive mesenchymal tumors, 4 malignant meningiomas, 3 malignant solitary fibrous tumors, 3 malignant peripheral nerve sheath tumors, 3 synovial sarcomas and 3 rhabdomyosarcomas (total 30 cases) were selected as control.Results:Among the 7 patients with primary intracranial DICER1-mutant sarcoma, 6 were male and 1 was female, aged 10-32 years (median, 23 years). The tissue morphology was predominantly spindle or pleomorphic sarcoma-like, with 6 cases exhibiting eosinophilic globules, and 3 cases showing rhabdomyoblastic or rhabdomyosarcoma-like cell differentiation. Immunohistochemistry revealed focal desmin expression in 3 cases (3/7), ATRX loss in 3 cases (3/7), and p53 mutant pattern in 4 cases (4/7). Additionally, 4 cases (4/7) showed focal or diffuse SALL4 expression, whereas the control cases (30 cases) did not exhibit SALL4 protein expression, suggesting that SALL4 may possess certain auxiliary diagnostic value. Next-generation sequencing confirmed that all 7 cases of primary intracranial DICER1-mutant sarcoma harbored mutations in the DICER1 gene, with 5 cases having the mutation site at p.E1813D. Until May 2024, all 7 patients were alive.Conclusions:Primary intracranial DICER1-mutant sarcoma is a rare tumor. Understanding its morphological characteristics, immunohistochemical and molecular markers and differential diagnosis is crucial to avoid misdiagnosis and to improve diagnostic accuracy of this tumor.
