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 explore the effect of NOD-like receptor thermal protein 3 ( NLRP3) knockout in γ-aminobutyric acid (GABA)-ergic neurons in the hippocampal CA1 area on improving cognitive dysfunction in mice after traumatic brain injury (TBI). Methods:Forty-eight healthy male NLRP3 flox/flox mice weighing 25-28 g were randomly divided into 4 groups ( n=12): sham-operated+control virus group (SV group), sham-operated+ NLRP3 specific knockout group (SG group), TBI+control virus group (TV group), TBI+ NLRP3 specific knockout group (TG group). TBI in the TV and TG groups was established by free-fall method, while surgical procedures such as scalp incision and cranial window opening without impact were given to the SV and SG groups. Adenovirus was injected into the hippocampal CA1 area of SG and TG groups 21 d before TBI to induce NLRP3 specific knockout in GABA-ergic neurons in the hippocampal CA1 area; empty virus was injected into the CA1 area of SV and TV groups. Cognitive function was evaluated using novel object recognition test 30 and 31 d after TBI, and learning and memory functions were assessed using Morris water maze test 32-36 d after TBI. Field potentials in the hippocampal CA1 area were recorded during novel object recognition 31 d after TBI. After behavioral tests, these mice were sacrificed. Immunofluorescent staining was used to detect the fluorescent intensity of microtubule-associated protein2 (MAP2), glutamic acid decarboxylase 67 (GAD67), and postsynaptic density protein 95 (PSD95) in the hippocampal CA1 area, as well as percentage of pyroptosis-associated inflammatory factor interleukin-18 (IL-18)/GAD67 double-positive neurons in total GAD67 positive neurons. Results:Compared with the SV and SG groups, the TV and TG groups had decreased novel object recognition index, decreased number of platform crossings during the experimental period, increased escape latency on day 3 and day 4 of the training period in Morris water maze test, decreased θ and γ oscillation power in the hippocampal CA1 area during novel object recognition, decreased fluorescent intensity of MAP2, GAD67, and PSD95 in the hippocampal CA1 area, increased percentage of IL-18/GAD67 double-positive neurons, with significant differences ( P<0.05). Compared with the TV group, the TG group had increased novel object recognition index, increased number of platform crossings in Morris water maze test, decreased escape latency during the training period, increased θ and γ oscillation power in the hippocampal CA1 area during novel object recognition, increased fluorescence intensity of MAP2, GAD67, and PSD95 in the hippocampal CA1 area, decreased percentage of IL-18/GAD67 double-positive neurons, with significant differences ( P<0.05). Conclusion:Specific inhibition of NLRP3 expression in GABA-ergic neurons in the hippocampal CA1 area can improve cognitive dysfunction in mice after TBI, whose mechanism may be related to inhibited GABA-ergic neuronal pyroptosis in the hippocampal CA1 area.

Objective:To compare the efficacy and safety of Castor single-branch stent and in vitro fenestration stent in treating thoracic aortic diseases with insufficient landing zone.Methods:The clinical data of patients with thoracic aortic diseases treated with Castor single-branch stent or in vitro fenestrated stent between December 2017 and June 2021 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. A total of 184 patients were included, 99 patients were treated with Castor branch stent, and 85 patients with in vitro fenestration stent. All patients′ general clinical data, surgical data, perioperative and follow-up clinical and imaging data, and postoperative complications were collected. The χ2 test was used to compare the incidence of complications between the two groups, and the Kaplan-Meier method was used to plot the survival rate without adverse events between the two groups. Results:Stent placement was successful in all patients, and the success rate of the technique was 100%. Other branches were reconstructed in 2 patients in the Castor group and double fenestrated stent were reconstructed in 12 patients in the fenestrated group. The mean operation time of the Castor group was significantly shorter than that of the fenestrated group, the number of patients who received local anesthesia was significantly lower than that of the fenestrated group, and the endoleak rate during follow-up was significantly lower than that of the fenestrated group ( P<0.05). There was no significant difference in the postoperative hospital stay, the incidence rate of perioperative complications, mortality, the incidence rate of neurological complications, new dissection or aneurysm rate, branch stent stenosis rate, second surgical intervention rate, and false lumen thrombosis between the two groups ( P>0.05). The adverse event-free survival rate of the Castor group was slightly higher than that of the fenestrated group, but its difference was not statistically significant ( P>0.05). Conclusion:Castor branch stent and in vitro fenestration stent have good short-term and mid-term efficacy in the treatment of aortic diseases with insufficient landing zone, which are safe and effective options for reconstruction of LSA and other branch arteries.

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.

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.
