    Abstract In this research, polyethylenimine-functionalized gold nanoclusters (PEI-AuNCs) were synthesized for the delivery of plasmid CMTM5 (pCMTM5) to prostate cancer (PCa) cells, with the objective of elucidating the mechanism underlying its anticancer efficacy. The PEI-AuNCs loaded with pCMTM5 (PEI-AuNCs@pCMTM5) tumor-targeting drug delivery system was established. Subsequently, both the obtained PEI-AuNCs and PEI-AuNCs@pCMTM5 underwent characterization through a transmission electron microscope (TEM) and dynamic light scattering (DLS). Employing RT-qPCR, western blot, flow cytometry, immunofluorescence, and co-immunoprecipitation (co-IP) assays, the consequences of CMTM5 overexpression on the expression of EGFR were investigated. Moreover, the influence of PEI-AuNCs@pCMTM5 on PC-3 cells was assessed through CCK-8, wound healing assay, and Transwell experiments. As a result, the PEI-AuNCs and PEI-AuNCs@pCMTM5 were presented as uniformly dispersed spherical with stable particle sizes and positive charges, showcasing favorable dispersion within the solution. In comparison to Lip2000, the PEI-AuNCs demonstrated superior transfection efficiency and lower cellular toxicity. Following the overexpression of CMTM5, the proliferative capacity of PC-3 cells was markedly suppressed, while both migratory and invasive abilities exhibited noteworthy reduction, with the efficacy of PEI-AuNCs@pCMTM5 consistently outperforming that of free pCMTM5. Subsequent mechanistic investigations unveiled that CMTM5 does not directly inhibit the synthesis of EGFR or facilitate its degradation, but rather influences the endocytic process of EGFR. In conclusion, the PEI-AuNCs nano-delivery system exhibits good biocompatibility and efficaciously conveys pCMTM5 to PCa cells. Crucially, pCMTM5 does not directly interact with EGFR, and CMTM5 governs the malignant progression of PC3 cells by promoting EGFR endocytosis.

    Abstract The rapid development of flexible electronics brings forward more requirements for self-healing substrate materials. Siloxane elastomers as an ideal substrate is widely used in the flexible electronics. However, self-healing siloxane elastomers still need to be improved in terms of mechanical properties. Herein, methacrylate/epoxy groups terminated hyperbranched polysiloxanes (HPBSi) as core was prepared to improve the mechanical properties via providing hierarchical permanent chemical cross-linked networks. A series of room-temperature self-healing siloxane elastomers are constructed by HPBSi with a linear dual-epoxy siloxane monomer through an amino disulfide compound (AFD) with reversible dynamic bonds. Especially, the content of HPBSi and AFD is systematically researched and proved to play a key role in adjusting the mechanical and self-healing properties of the siloxane elastomers. For the P1-5 containing 5 wt% HPBSi, its tensile strength is as high as 0.87 MPa that is improved about 410% compared with an elastomer without HPBSi. P11-5 elastomer with more AFD can obtain the same healing efficiency at room temperature in a shorter time (12 h) compared with 48 h of P1-5 elastomer. Finally, the self-healing siloxane is used as a flexible substrate to fabricate a strain sensor for monitoring multiple human motions, demonstrating a promising potential use in the flexible electronics.

    Abstract Background: Aberrant activation of androgen receptor (AR) signaling plays a crucial role in the progression of prostate adenocarcinoma (PRAD) and contributes significantly to the development of enzalutamide resistance. In this study, we aimed to identify a novel AR-driven signature that can predict prognosis and endows potentially reveal novel therapeutic targets for PRAD.
    Methods: The Seurat package was used to preprocess the single-cell RNA sequencing (scRNA-seq). Differentially expressed genes were visualized using limma and pheamap packages. LASSO and multi-variate Cox regression models were established using glmnet package. The package "Consensus Cluster Plus" was utilized to perform the consensus clustering analysis. The biological roles of origin recognition complex subunit 1 (ORC1) in PRAD were determined by gain- and loss-of-function studies
    Result: We characterized the scRNA-seq data from GSE99795 and identified 10 AR-associated genes (ARGs). The ARGs model was trained and validated in internal and external cohorts. The ARGs were identified as an independent hazard factor in PRAD and correlated with clinical risk characteristics. In addition, the ARGs were found to be correlated with somatic tumor mutation burden (TMB) levels. Two groups that have distinct prognostic and molecular features were identified through consensus clustering analysis. ORC1 was identified as a critical target among these ARGs, and it ORC1 promoted proliferation and stem-like properties of PRAD cells. Chromatin immunoprecipitation (ChIP)-qPCR assay confirmed that AR could directly bind the promoter of ORC1. Activated AR/ORC1 axis contributed to enzalutamide resistance, and targeting ORC1 rendered PRAD cells more susceptible to enzalutamide.
    Conclusions: This study defines an AR-driven signature that AR activates ORC1 expressions to promote PRAD progression and enzalutamide resistance, which may provide novel targets for PRAD treatment.

    Abstract Objective: Despite advancements in spinal metastasis surgery techniques and the rapid development of multidisciplinary treatment models, we aimed to explore the clinical efficacy of spinal metastasis surgery performed by a combined NOMS decision system-utilizing multidisciplinary team and Revised Tokuhashi scoring system, compared with the Revised Tokuhashi scoring system.
    Methods: Clinical data from 102 patients with spinal metastases who underwent surgery at three affiliated hospitals of Zunyi Medical University from December 2017 to June 2022 were analysed. The patients were randomly assigned to two groups: 52 patients in the treatment group involving the combined NOMS decision system-utilizing multidisciplinary team and Revised Tokuhashi scoring system (i.e., the combined group), and 50 patients in the treatment group involving the Revised Tokuhashi scoring system only (i.e., the revised TSS-only group). Moreover, there were no statistically significant differences in preoperative general data or indicators between the two groups. Intraoperative and postoperative complications, average hospital stay, mortality rate, and follow-up observation indicators, including the visual analogue scale (VAS) score for pain, Eastern Cooperative Oncology Group (ECOG) performance status, Karnofsky Performance Status (KPS) score, negative psychological assessment score (using the Self-Rating Anxiety Scale, [SAS]), and neurological function recovery score (Frankel functional classification) were compared between the two groups.
    Results: All 102 patients successfully completed surgery and were discharged. The follow-up period ranged from 12 to 24 months, with an average of (13.2 ± 2.4) months. The patients in the combined group experienced fewer complications such as surgical wound infections 3 patients(5.77%), intraoperative massive haemorrhage 2 patients(3.85%), cerebrospinal fluid leakage 2 patients(3.85%), deep vein thrombosis 4 patients(7.69%),and neurological damage 1 patient(1.92%), than patients in the revised TSS-only group (wound infections,11 patients(22%); intraoperative massive haemorrhage, 8 patients(16%);cerebrospinal fluid leakage,5 patients(10%);deep vein thrombosis,13 patients (26%); neurological damage,2 patients (4%). Significant differences were found between the two groups in terms of surgical wound infections, intraoperative massive haemorrhage, and deep vein thrombosis (P < 0.05). The average postoperative hospital stay in the combined group (7.94 ± 0.28 days) was significantly shorter than that in the revised TSS-only group (10.33 ± 0.30 days) (P < 0.05). Long-term follow-up (1 month, 3 months, 6 months, and 1 year postoperatively) revealed better clinical outcomes in the combined group than in the revised TSS-only group in terms of VAS scores, overall KPS%, neurological function status Frankel classification, ECOG performance status, and SAS scores.(P < 0.05).
    Conclusion: A multidisciplinary team using the NOMS combined with the Revised Tokuhashi scoring system for spinal metastasis surgery showed better clinical efficacy than the sole use of the Revised Tokuhashi scoring system. This personalized, precise, and rational treatment significantly improves patient quality of life, shortens hospital stay, reduces intraoperative and postoperative complications, and lowers mortality rates.

    Abstract Background: Multivisceral en bloc resection with the ipsilateral kidney is commonly performed in patients with retroperitoneal liposarcoma (RLPS). We evaluated the effect of nephrectomy on short- and long-term outcomes in patients with RLPS.
    Methods: Data from a prospectively maintained database of the Peking University Cancer Hospital Sarcoma Center between April 2011 and August 2022 were analyzed. We classified the RLPS patients who underwent surgery into nephrectomy group (NP) and non-nephrectomy group (non-NP). Patients were matched using a 1:1 propensity score to eliminate baseline differences between groups. Postoperative renal function outcomes, major morbidity, and mortality were analyzed to compare short-term outcomes after nephrectomy. Differences in local recurrence-free survival (LRFS) and overall survival (OS) were compared by Kaplan-Meier analysis with respect to oncological benefits.
    Results: In the matched cohort, patients in the NP group had significantly higher postoperative eGFR and CKD stages, but none required dialysis. Patients between NP and non-NP had a comparable major morbidity (p = 0.820) and 60-day mortality (p = 0.475). Patients in the NP group had a higher 5-year LRFS rates than those in the non-NP group (34.5 vs. 17.8%, p = 0.015), and similar 5-year OS rates (52.4 vs. 47.1%, p = 0.401). Nephrectomy was an independent risk factor for LRFS, but not for major morbidity or OS.
    Conclusions: RLPS resection with nephrectomy is related to a mild progression of renal impairment; however, dialysis is rare. En bloc nephrectomy for complete resection of RLPS is safe and improves local control.
