Objective To explore the effects of Yin Yang 1(YY1)on the proliferation and migration of bladder cancer cells and investigate the underlying mechanisms,so as to provide reference for the prevention and treatment of this disease.Methods The expression patterns of YY1 in common genitourinary tumors and their associations with the prognosis were analyzed using data from The Cancer Genome Atlas(TCGA)and the Gene Expression Omnibus(GEO).The efficiency of YY1 knockdown and overexpression in bladder cancer cell lines(T24 and UM-UC-3)was confirmed with quantitative reverse transcription PCR(qRT-PCR)and Western blotting.Cell proliferation and migration were assessed using methylthiazolyldiphenyl-tetrazolium bromide(MTT)and Transwell assays.RNA sequencing followed by bioinformatics analyses,including Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),and Gene Set Enrichment Analysis(GSEA),was conducted to predict potential mechanisms.The qRT-PCR and rescue experiments were performed to validate whether YY1 exerted its effects via the E2F1 signaling pathway.Results YY1 was significantly overexpressed in bladder cancer compared to other genitourinary tumors and was associated with higher tumor grade and poorer prognosis(P＜0.05).Functional assays demonstrated that YY1 promoted the proliferation and migration of bladder cancer cells.Transcriptome analyses revealed that YY1 might regulate these processes through the E2F signaling pathway.Moreover,overexpression of E2F1 partially reversed the inhibitory effects of YY1 knockdown on bladder cancer cell proliferation and migration.Conclusion YY1 is upregulated in bladder cancer and is closely associated with tumor grade and unfavorable prognosis.It may facilitate tumor cell proliferation and migration by modulating the E 2F1 signaling pathway.

Objective:To investigate brain damage and treatment efficacy in patients with first-episode schizophrenia with comorbid auditory and visual hallucinations and cognitive decline based on brain magnetic resonance imaging (MRI).Methods:This study adopted a retrospective cohort design. Eighty patients with first-episode schizophrenia who received treatment at Wenzhou Seventh People's Hospital from January to June 2024 were included in this study. The patients were divided into an observation group (40 cases of first-episode schizophrenia with comorbid auditory and visual hallucinations) and a control group (40 cases of first-episode schizophrenia without comorbid auditory and visual hallucinations) based on whether they had symptoms of comorbid auditory and visual hallucinations. Forty healthy individuals who concurrently underwent physical examinations were included in the normal group. All patients received standardized treatment. Cranial MRI data were collected from all subjects. Cranial MRI data, Positive and Negative Syndrome Scale (PANSS) score, Global Assessment of Functioning (GAF) score, and changes in cognitive function were compared among the three groups. Additionally, the changes in cranial MRI data, PANSS score, GAF score, and the score of MATRICS Consensus Cognitive Battery (MCCB) in the observation group were compared between before and after treatment.Results:The horizontal distance between the corpus callosum and the underside of the cingulate gyrus, the vertical distance between the corpus callosum and the underside of the cingulate gyrus, and PANSS and GAF scores in the observation group were all significantly higher than those in the normal and control groups (all P < 0.05). The scores on all MCCB scales in the observation group were significantly lower than those in the normal and control groups (all P < 0.05). After treatment, the left horizontal distance between the corpus callosum and the underside of the cingulate gyrus [(5.72 ± 0.71) mm] and the right horizontal distance [(5.13 ± 0.55) mm], as well as the left vertical distance [(6.37 ± 0.69) mm] and the right vertical distance [(5.61 ± 0.67) mm], were all significantly lower than the pre-treatment values [(6.98 ± 0.83) mm, (6.07 ± 0.49) mm, (7.54 ± 0.58) mm, and (6.52 ± 0.51) mm, t = 7.30, 8.07, 8.21, 6.84, all P < 0.05]. Post-treatment PANSS scores [(39.95 ± 6.65)] were significantly lower than pre-treatment scores [(97.47 ± 18.47)], while post-treatment GAF scores [(71.26 ± 8.87)] were significantly higher than pre-treatment scores [(34.68 ± 7.71), t = 18.53, 19.69, both P < 0.05]. Post-treatment scores for the MCCB [(8.57 ± 2.45), (2.25 ± 0.47), (25.16 ± 2.43), (24.10 ± 2.64), (17.08 ± 2.25), (20.43 ± 3.76), (2.07 ± 0.36), (22.16 ± 3.24), (57.81 ± 7.69), (0.28 ± 0.05)] were significantly higher than pre-treatment scores [(5.65 ± 1.37), (1.62 ± 0.34), (21.21 ± 2.27), (20.27 ± 1.78), (12.16 ± 2.08), (14.56 ± 2.34), (1.71 ± 0.25), (17.92 ± 1.64), (40.29 ± 6.56), (0.21 ± 0.03), t = 6.58, 6.87, 7.51, 7.61, 10.15, 8.38, 5.19, 7.38, 10.96, 7.59, all P < 0.05]. Conclusions:The comorbid auditory and visual hallucinations in patients with first-episode schizophrenia, based on brain MRI findings, are closely related to cognitive decline and brain damage. After treatment, both cognitive function and cranial damage in these patients have considerably improved, which is worthy of clinical consideration.

Traditional Chinese medicine(TCM), with diverse structural types of active components and remarkable clinical efficacy, holds a significant position in the pharmacological research. As the key substances, active components of TCM are of great importance in revealing the material basis of TCM efficacy and mechanism of action. However, the conventional approaches of discovering active components in TCM are characterized by tedious procedures, lengthy cycles, and unclear mechanisms, which struggle to meet the current demands for drug development. In recent years, major breakthroughs have been made in target discovery technologies, and new drug targets are constantly being discovered, which has facilitated the development of target-driven approaches. The target-guided active component discovery strategy provides a new paradigm for discovering active components in TCM. This article systematically summarizes two mainstream target-based technologies-virtual screening and ligand fishing-for TCM active component discovery. By analyzing relevant application cases, this article evaluates the strengths and limitations of each technology. The review aims to provide frameworks for expediting bioactive component discovery in complex systems like TCM, so as to accelerate the development of innovative drugs based on the active components of TCM and promote the modernization and internationalization of TCM.

This study aimed to explore the mechanisms and molecular targets of total flavones of Abelmoschus manihot(TFA) plus empagliflozin(EM) in attenuating diabetic tubulopathy(DT) by targeting mitochondrial homeostasis and pyroptosis-apoptosis-necroptosis(PANoptosis). In the in vivo study, the authors established the DT rat models through a combination of uninephrectomy, administration of streptozotocin via intraperitoneal injections, and exposure to a high-fat diet. Following modeling successfully, the DT rat models received either TFA, EM, TFA+EM, or saline(as a vehicle) by gavage for eight weeks, respectively. In the in vitro study, the authors subjected the NRK52E cells with or without knock-down Z-DNA binding protein 1(ZBP1) to a high-glucose(HG) environment and various treatments including TFA, EM, and TFA+EM. In the in vivo and in vitro studies, The authors investigated the relative characteristics of renal tubular injury and renal tubular epithelial cells damage induced by reactive oxygen species(ROS), analyzed the relative characteristics of renal tubular PANoptosis and ZBP1-mediatted PANoptosis in renal tubular epithelial cells, and compared the relative characteristics of the protein expression levels of marked molecules of mitochondrial fission in the kidneys and mitochondrial homeostasis in renal tubular epithelial cells, respectively. Furthermore, in the network pharmacology study, the authors predicted and screened targets of TFA and EM using HERB and SwissTargetPrediction databases; The screened chemical constituents and targets of TFA and EM were constructed the relative network using Cytoscape 3.7.2 network graphics software; The relative targets of DT were integrated using OMIM and GeneCards databases; The intersecting targets of TFA, EM, and DT were enriched and analyzed signaling pathways by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG) software using DAVID database. In vivo study results showed that TFA+EM could improve renal tubular injury, the protein expression levels and characteristics of key signaling molecules in PANoptosis pathway in the kidneys, and the protein expression levels of marked molecules of mitochondrial fission in the kidneys. And that, the ameliorative effects in vivo of TFA+EM were both superior to TFA or EM. Network pharmacology study results showed that TFA+EM treated DT by regulating the PANoptosis signaling pathway. In vitro study results showed that TFA+EM could improve ROS-induced cell injury, ZBP1-mediatted PANoptosis, and mitochondrial homeostasis in renal tubular epithelial cells under a state of HG, including the protein expression levels of marked molecules of mitochondrial fission, mitochondrial ultrastructure, and membrane potential level. And that, the ameliorative effects in vitro of TFA+EM were both superior to TFA or EM. More importantly, using the NRK52E cells with knock-down ZBP1, the authors found that, indeed, ZBP1 was mediated PANoptosis in renal tubular epithelial cells as an upstream factor. In addition, TFA+EM could regulate the protein expression levels of marked signaling molecules of PANoptosis by targeting ZBP1. In summary, this study clarified that TFA+EM, different from TFA or EM, could attenuate DT with multiple targets by ameliorating mitochondrial homeostasis and inhibiting ZBP1-mediated PANoptosis. These findings provide the clear pharmacological evidence for the clinical treatment of DT with a novel strategy of TFA+EM, which is named "coordinated traditional Chinese and western medicine".

Exosomes, as crucial mediators of intercellular communication, exhibit a wide range of biological functions in the onset and treatment of atherosclerosis (AS). Recent studies have indicated that exosomes can carry various active substances, including miRNA, lncRNA, proteins, and lipids. By regulating inflammatory responses, lipid metabolism, vascular endothelial function, and the immune microenvironment, they mediate the formation, progression, and reversal of AS at multiple levels. Specifically, miRNAs within exosomes can target and regulate the expression of inflammatory factors, inhibiting macrophage activation and foam cell formation. Meanwhile, exosomes derived from endothelial cells (EC) or stem cells can enhance vascular endothelial integrity and suppress endothelial dysfunction (ED). Furthermore, exosomes have been extensively explored as natural carriers for delivering drugs and nucleic acid molecules. Their membrane structure possesses excellent biocompatibility and targeting capabilities, showcasing significant potential as a novel therapeutic tool. Starting from basic mechanistic studies, this article summarizes the molecular pathways and key biological effects of exosomes in AS intervention, and further explores their current clinical application and multiple challenges they face, aiming to provide theoretical support and research directions for novel cardiovascular disease intervention strategies.

Among the 135 patients, 122 (90.4%) were distal pancreatectomies, 8 (5.9%) were pancreaticoduodenectomies, 4 (3.0%) were total pancreatectomies and 1 (0.7%) was resection for local recurrence after distal pancreatectomy. There were 120 (88.9%) celiac axis resections, 11 (8.1%) hepatic artery resections, 1 (0.7%) superior mesenteric artery resection and 3 (2.2%) other artery resections. Simultaneous portal vein-superior mesenteric vein or organ resection accounted for 26.7% (36/135) and 29.6% (40/135),respectively. The median blood loss was 300 (300) ml and the median operation time was 275 (105) minutes. The 90-day mortality rate was 7.4% (10/135). The overall morbidity rate was 70.4% (95/135) while the major morbidity rate was 18.5% (25/135). Postoperative hemorrhage occurred in 8.9% (12/135), clinically relevant postoperative pancreatic fistula in 57.0% (77/135), bile leak in 0.74% (1/135), delayed gastric emptying in 9.6% (13/135), liver failure in 3.7% (5/135) and transient liver enzyme elevation in 44.4% (60/135). All of the 135 cases were confirmed as pancreatic cancer histologically, including 54.6% (71/130) moderately differentiated, 45.4% (59/130) poorly differentiated and no for well differentiated. The median tumor size was 4.5 (2.3) cm. The median number of harvested lymph nodes was 14 (13) and the percentage of N0, N1 and N2 according to AJCC 8th staging system was 27.1% (36/133), 52.6% (70/133) and 20.3% (27/133), respectively. The R 0 resection was achieved in 40 of 123 cases (32.5%), whose margins of specimens were assessed circumferentially based on the 1mm rule. The median overall survival time (MST) after surgery was 22.5 months, and the median progress-free survival time was 16.1 months. The overall survival rate at 1-, 2- and 5-year was 71.5%, 45.1% and 11.3%, respectively. The MST of patients who received no adjuvant therapy, chemotherapy after surgery was 8.4 months, 25.3 months, respectively. Conclusions:Pancreatectomy with arterial resection is generally safe and feasible. Survival outcome improves significantly when combined with adjuvant chemotherapy.
