Aim To investigate the protective effect of Vaccarin(Va)on epithelial-mesenchymal transition(EMT)in renal fibrosis model mice through regulating STAT3,and the underlying mechanism.Methods Left ureter ligation was used to establish a mouse model of unilateral ureteral obstruction(UUO);human kid-ney tubular epithelial(HK2)cells were induced to differentiate by transforming growth factor-β(TGF-β)in vitro.HE and Masson staining were used to observe the morphological changes of renal tissue;kits were used to detect the levels of BUN,Cr,IL-1β and IL-7 in mouse serum;CCK-8 was used to detect the effect of Va on the viability of HK2 cells;RT-PCR was used to detect the levels of inflammatory factors in HK2 cells;Western blot was used to detect the expression of STAT3,p-STAT3,E-cadherin,and α-SMA proteins in renal tissue and HK2 cells;to further investigate the regulation of Va on STAT3,JAK/STAT3 pathway acti-vator RO8191 was used to treat TGF-β-induced HK2 cells,and functional loss was detected.Results Va improved the pathological damage in UUO mice,inhibi-ted the levels of BUN,Cr and inflammatory factors;Va inhibited the phosphorylation of STAT3,upregulated E-cadherin,and downregulated α-SMA protein expres-sion;RO8191 counteracted the inhibitory effect of Va on the phosphorylation of STAT3.Conclusions Va inhibits the phosphorylation of STAT3 and the release of inflammatory factors,improves EMT,thus exerting an anti-renal fibrosis effect.

OBJECTIVE: To explore the potential effects and mechanisms of Liang-Ge-San (LGS) for the treatment of acute respiratory distress syndrome (ARDS) through network pharmacology analysis and to verify LGS activity through biological experiments. METHODS: The key ingredients of LGS and related targets were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. ARDS-related targets were selected from GeneCards and DisGeNET databases. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed using the Metascape Database. Molecular docking analysis was used to confirm the binding affinity of the core compounds with key therapeutic targets. Finally, the effects of LGS on key signaling pathways and biological processes were determined by in vitro and in vivo experiments. RESULTS: A total of LGS-related targets and 496 ARDS-related targets were obtained from the databases. Network pharmacological analysis suggested that LGS could treat ARDS based on the following information: LGS ingredients luteolin, wogonin, and baicalein may be potential candidate agents. Mitogen-activated protein kinase 14 (MAPK14), recombinant V-Rel reticuloendotheliosis viral oncogene homolog A (RELA), and tumor necrosis factor alpha (TNF-α) may be potential therapeutic targets. Reactive oxygen species metabolic process and the apoptotic signaling pathway were the main biological processes. The p38MAPK/NF-κ B signaling pathway might be the key signaling pathway activated by LGS against ARDS. Moreover, molecular docking demonstrated that luteolin, wogonin, and baicalein had a good binding affinity with MAPK14, RELA, and TNF α. In vitro experiments, LGS inhibited the expression and entry of p38 and p65 into the nucleation in human bronchial epithelial cells (HBE) cells induced by LPS, inhibited the inflammatory response and oxidative stress response, and inhibited HBE cell apoptosis (P<0.05 or P<0.01). In vivo experiments, LGS improved lung injury caused by ligation and puncture, reduced inflammatory responses, and inhibited the activation of p38MAPK and p65 (P<0.05 or P<0.01). CONCLUSION LGS could reduce reactive oxygen species and inflammatory cytokine production by inhibiting p38MAPK/NF-κ B signaling pathway, thus reducing apoptosis and attenuating ARDS.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective Responding to the imperative to modernize vocational education and establish competency-oriented systems,this study investigates the development of on-campus training bases for speech and hearing rehabilitation(SHR)programs within Chinese higher vocational colleges(HVC).It analyzes their functional role and essential compo-nents,and propose a competency-oriented,modular framework for on-campus training based on World Health Organization(WHO)rehabilitation competency framework(RCF),and professional education standards.Methods This research synthesized theories of higher vocational education and practical pedagogy(e.g.,situated learn-ing,experiential learning and constructivism)with analyses of domestic and international SHR educational poli-cies and standards.It examined the strategic importance and essential components(hardware,software,human re-sources,management)of on-campus training bases in the context of higher vocational education.Synthesizing RCF with standards from ASHA(knowledge and skills acquisition,KASA),International Association of Logope-dics and Phoniatrics(IALP),and Teaching Standards for Higher Vocational Schools from Ministry of Education of the People's Republic of China,a core SHR professional competency model tailored for HVC was developed.This model subsequently guided the design of a modular on-campus training curriculum and associated pedagogi-cal approaches.Results On-campus training bases were pivotal platforms that bridge theory and practice,facilitating'teaching-learning-doing'integration within HVC SHR programs.Effective base construction necessitated synergistic integration across four key domains:hardware facilities(meeting specialized acoustic/equipment needs),software resources(case libraries,standard operating procedure and digital tools),'dual-role'human resources and robust manage-ment systems(operations,evaluation,industry-education linkages).Derived from RCF and related standards,a core SHR competency framework was developed,encompassing dimensions such as foundational knowledge and ethics,assessment(audiological;speech-language),intervention(audiological rehabilitation and technology;speech-language),and communication and collaboration.Consequently,eight core training modules were de-signed,including basic operations of hearing testing,introduction to objective hearing testing,preliminary hear-ing aid fitting,application of standardized speech-language assessment tools,simulation of articulation and voice disorder assessment and intervention,simulation of swallowing disorder screening and basic training,comprehen-sive case analysis and rehabilitation plan development,and practice of professional literacy and communication skills;detailing objectives,activities,and resources,and intended for seamless integration with theoretical cours-es and off-campus practicum,establishing a cohesive'curriculum-training-practicum'continuum.Furthermore,a suite of adaptable pedagogical models,including problem-based learning,case-based learning,simulation-based training,project-based learning and the flipped classroom,were recommended for implementing these modules.Conclusion The effective development of on-campus training bases for SHR programs in HVC necessitates establishing a systematic,competency-oriented practical teaching environment.Grounded in RCF,and essential SHR knowl-edge,skills and abilities,this study proposes a framework incorporating eight core training modules and comple-mentary pedagogical models,providing a theoretically grounded,practically applicable blueprint for enhancing the educational quality and substance of these bases within HVC.Successful realization hinges upon the synergis-tic development of the four key elements(hardware,software,human resources,management),deep integration between training activities,the curriculum,and practicum experiences,and the application of innovative pedago-gy to cultivate student potential.

Aim To investigate the impact of G pro-tein-coupled estrogen receptor 1(GPER1),also known as GPR30 playing a significant role in the nerv-ous system,on neuronal damage and cognitive dysfunc-tion following epileptic seizures.Methods The pro-tein expression levels of GPER1 and the DNA damage marker γ-H2AX in epileptic rats were assessed using Western blot.The hippocampal neuronal damage and apoptosis in pilocarpine-induced epilepsy models were evaluated using Nissl and TUNEL staining techniques,compared with GPER1 knockdown(GPER1-KD)rats with wild-type(WT)controls.The behavioral activi-ties,including memory and spatial learning,were mo-nitored during the chronic phase of epilepsy using the IntelliCage system.Results Compared to the control group,GPER1 protein expression in the cerebral cortex and hippocampus significantly increased 24 hours post-epilepsy onset.In the GPER1-KD+EP group,hipp-ocampal neuronal damage was more severe,with a sig-nificant increase in apoptotic neurons compared to the WT+EP group.The IntelliCage data revealed that during free exploration,nose contact,position learn-ing,and reverse position learning stages in the GPER1-KD+EP group exhibited fewer visits and a higher error rate than in the WT+EP group.Conclu-sions Deficiency in GPER1 impairs memory and spa-tial learning abilities following epilepsy,potentially due to exacerbated neuronal injury,apoptosis,and inflam-mation.GPER1 represents a promising therapeutic tar-get for mitigating post-epileptic nerve damage and cog-nitive impairment.

Objective To analyse the clinical efficacy and safety of acupuncture combined with intermittent catheterisation in treating postoperative urinary retention after radical surgery for cervical cancer,and provide reference for the clinical treatment of postoperative urinary retention.Methods A retrospective analysis was conducted based on the clinical data of patients who underwent radical hysterectomy for cervical cancer at Obstetrics and Gynecology Hospital,Fudan University,from Sept 2019 to Dec 2021 and subsequently developed urinary retention.The patients were treated with a combination of acupuncture and intermittent catheterization.We observed residual urine volume,duration of acupuncture treatment,and urinary tract infection status to evaluate the effectiveness and safety of the acupuncture combined with intermittent catheterization regimen.We examined the relationship between treatment duration and various factors such as age,pathological type,surgical-pathological staging,surgical method,pre-treatment catheter indwelling time,pre-treatment residual urine volume,presence or absence of postoperative radiotherapy and chemotherapy,pre-existing urinary tract infection,and whether ureteral stenting was performed,in order to analyze the factors affecting the treatment duration.Results A total of 156 patients were reviewed.After treatment,132 cases had a post-treatment residual urine volume<100 mL,7 cases had a volume of 100-200 mL,and 15 cases had a volume>200 mL.Two cases still had great difficulty in urination after treatment,resulting in an overall effectiveness rate of 89.1%.No significant adverse events occurred in the patients.The treatment duration ranged from 2 to 17 days,with an average treatment time of 6.2 days.The treatment duration was a correlated with the preoperative indwelling catheter duration,residual urine volume and postoperative radiotherapy.Conclusion Acupuncture combined with intermittent catheterisation in treating urinary retention after radical surgery for cervical cancer has good efficacy,short treatment time and no obvious adverse effects,and can be an option for treating postoperative urinary retention.
