ObjectiveTo analyze the research hotspots and development trends in the field of spinal cord stimulation (SCS) for spinal cord injury (SCI). MethodsLiterature about SCS for SCI was retrieve from the Web of Science (WOS) Core Collection database, with a time range from January, 1999 to July, 2025. VOSviewer 1.6.20 and CiteSpace 6.4.R2 were used to analyze the annual publication volume, countries, authors, institutions, journals and keywords. ResultsA total of 636 literatures were included. From 1999 to 2025, the overall publication trend in this field showed an upward trajectory, with recent years fluctuating but tending to stabilize. The country with the most publications was the United States (429 papers), followed by Russia (98 papers) and China (70 papers). The institution with the highest number of publications was the University of California, Los Angeles (76 papers), the author with the most publications was V. Reggie Edgerton (70 papers), and the journal with the most publications was Journal of Clinical Medicine (31 papers). The most frequently cited study focused on exploring the combination of epidural spinal cord stimulation with task-specific training to restore motor function in patients with complete SCI. Keyword analysis showed that the research hotspots in this field were mainly focused on neuroregulation mechanisms, recovery of motor and autonomic nervous dysfunction, artificial intelligence, closed-loop stimulation and brain-computer interface technology innovations. In recent years, the research focus gradually shifted from basic mechanisms to personalized and precise multifunctional rehabilitation strategies. ConclusionThe field of SCS for SCI has undergone phases of basic mechanism exploration and clinical application expansion. Current research hotspots and future trends focus primarily on the development of new stimulation paradigms and combined innovative technologies.

Objective:The objective of this study is to analyze the detection rate, the pathogenic fungus distribution, risk factors and drug sensitivity of fungal infection of external auditory canal in patients diagnosed with chronic otitis media. Methods:The data of a total of 419 patients with chronic suppurative otitis media or middle ear cholesteatoma who were admitted from January 2019 to February 2023 were retrospectively analyzed. Results:A total of 419 patients were included, and 71 patients（16.9%） were positive for fungal culture. The disease mostly occurred in subjects aged 51-60 years old, and patients over 60 years old（47 cases, 66.2%）. From the fungal culture of external auditory canal secretions, 48 cases（11.4%） of Aspergillus and 14 cases（3.3%） of Candida were identified. The prevalence of fungal cultures in patients with chronic suppurative otitis media（20.8%） was significantly higher than that in patients with middle ear cholectestoma（4.9%）. The detection rate of Fungal was significantly increased after topical treatment with antibiotic ear drops（47.0% vs 13.6%）. Most of the isolated fungal strains are wild-type, and they are the sensitivity to voriconazole and fluconazole was the highest（97.2%）. For patients with positive fungal culture, iodoform gauze with triamcinolone acetonide and econazole cream was used to fill the external auditory canal during surgery. There was no significant difference in the tympanic membrane healing rate between patients with positive fungal culture and patients with negative fungal culture at 3 weeks after surgery（98.6% vs 97.7%）. Conclusion:Fungal infections of external auditory canal in patients with chronic otitis media tend to occur in older patients, which is more common in patients with chronic suppurative otitis media. Long-term topical treatment with antibiotic ear drops is an independent risk factor for fungal infection of external auditory canal in patients with chronic otitis media. The isolated fungal strains were highly sensitive to antifungal drugs. Therefore, it is advisable to refrain from employing topical antibiotic treatment for elderly patients with chronic suppurative otitis media/middle ear cholesteatoma, abuse of local antibiotic therapy should be avoided, and Fungal-related pathogenic examinations should be actively performed and anti-fungal drugs should be added if necessary.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.

Algorithmic systems based on artificial intelligence(AI)and machine learning(ML)have undergone rapid advancement in recent years, demonstrating extensive application across diverse ophthalmic disorders. Owing to the public availability of multiple global databases, significant progress has been achieved in the training and development of AI-integrated algorithms utilizing multimodal ophthalmic imaging modalities, including fundus photography and optical coherence tomography(OCT). These advancements have established a foundation for precision medicine and efficient healthcare delivery. The diagnosis of macular diseases relies on the identification of subtle alterations in tissue anatomy, where AI demonstrated exceptional performance in detecting intraocular biomarkers and evaluating anatomical changes during disease progression, with particularly prominent utility in the field of macular pathologies. This article provides a comprehensive review of the current applications of AI in macular diseases, aiming to synthesize existing research achievements and current challenges, while proposing visionary prospects for the broader implementation of AI in ophthalmology and even systemic medicine in the future.

Objective:To observe the changes in choroidal morphology and blood perfusion in patients with macular edema secondary to retinal vein occlusion (RVO) after intravitreal injections of ranibizumab.Methods:A cohort study was performed.A total of 157 patients (157 eyes) with macular edema secondary to monocular acute retinal vein occlusion (RVO) were enrolled in the Third People's Hospital of Dalian from January 2022 to March 2023.There were 66 cases (66 eyes) with central retinal vein occlusion (CRVO) and 91 cases (91 eyes) with branch retinal vein occlusion (BRVO).All patients were treated with 3+ pro re nata (PRN) regimen of ranibizumab.Before and 1 month after each injection, the central retinal thickness of the macula was measured by optical coherence tomography (OCT).Clear images of the choroid were obtained using the OCT enhanced depth scan mode.Subfoveal choroidal thickness (SFCT), the nasal choroidal thickness at 1 500 μm of macula (CT N1.5 mm), the temporal choroidal thickness at 1 500 μm of macula (CT T1.5 mm) were measured and mean macular thickness (CT Mean) was calculated.Binarization of choroidal images processed by ImageJ software was used to analyze luminal area (LA), stromal area (SA) and total choroidal area (TCA), and choroidal vascularity index (CVI) was calculated.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the Third People's Hospital of Dalian (No.2023-145-001).Results:SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI of RVO eyes were higher than those of the contralateral eyes and the differences were statistically significant (all P<0.01).CT Mean in CRVO group was (326.99±64.92)μm, which was higher than (299.80±73.08)μm in BRVO group, with a statistically significant difference ( t=2.41, P=0.02).Baseline CVI values in CRVO group and BRVO group were (72.50±5.62)% and (72.33±5.85)%, respectively, with no significant difference ( t=0.187, P=0.85).In eyes with RVO, CRVO and BRVO, SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI after every injection were lower than the baseline and the differences were statistically significant (all P<0.05).In eyes with CRVO, there was no significant difference in LA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with BRVO, there was no significant difference in SA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with RVO, CRVO and BRVO, there was no significant difference in SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA, TCA and CVI between second and third injections (all P>0.05). Conclusions:After intravitreal injection of ranibizumab, the choroidal thickness becomes thinner and CVI decreases in eyes with macular edema secondary to RVO, and remain relatively stable after the second injection.

Objective To investigate the expression of the circular RNA circ-PHC3 in cervical cancer tissues and its regulatory mechanisms in the proliferation,migration,and invasion of cervical cancer cells.Methods The expression levels of circ-PHC3 in cervical cancer tissues and adjacent non-tumor tissues were analyzed using the GEO database.The correlation between circ-PHC3 expression and the clinical stage as well as prognosis of cervical cancer patients was also evaluated.The expression of circ-PHC3 in cervical cancer cell lines HCC94,C33A,HeLa,HCC1106,and SiHa was detected by real-time quantitative polymerase chain reaction(qRT-PCR).The cell line with the highest circ-PHC3 expression was selected for transfection with a circ-PHC3 inhibitor.The interaction between circ-PHC3 and miR-1179 was validated using a dual luciferase reporter gene assay.The expression levels of miR-1179 in transfected cells were further assessed by qRT-PCR.Functional assays,including colony formation,flow cytometry,wound healing,and Transwell assays,were conducted to evaluate cell proliferation,cell cycle progression,migration,and invasion,respectively.Western blot analysis was performed to determine the expression of key proteins associated with proliferation,migration,and invasion in circ-PHC3-modulated cells.Finally,in vivo experiments were carried out to investigate the impact of circ-PHC3 silencing on the growth and metastasis of cervical cancer cells in animal models.Results The expression level of circ-PHC3 in cervical cancer tissues was significantly higher than that in adjacent normal tissues(P<0.01).Furthermore,circ-PHC3 expression was significantly associated with the clinical stage of cervical cancer(P<0.01).Patients with high circ-PHC3 expression exhibited a notably lower survival rate compared to those with low circ-PHC3 expression(P<0.01).In cervical cancer cell lines including HCC94,C33A,HeLa,HCC1106,and SiHa,circ-PHC3 expression was markedly upregulated(all P<0.01),with the highest expression observed in HCC1106 cells(P<0.01).Circ-PHC3 was found to directly interact with miR-1179(P<0.01),and silencing circ-PHC3 significantly increased miR-1179 expression(P<0.01).Transfection of HCC1106 cells with a circ-PHC3 inhibitor significantly suppressed cell proliferation,migration,and invasion(all P<0.01),and induced cell cycle arrest(P<0.01);these effects were partially reversed by co-transfection with a miR-1179 inhibitor(all P<0.05).In HCC1106 cells with circ-PHC3 knockdown,the expression levels of key proteins associated with proliferation,migration,and invasion—Cyclin E,CDK2,MMP-9,and N-cadherin—were significantly reduced(all P<0.01),and this reduction was partially attenuated by miR-1179 inhibition(all P<0.01).In vivo experiments further demonstrated that circ-PHC3 knockdown significantly inhibited tumor growth and metastasis of HCC1106 cells(all P<0.01).Conclusions Circ-PHC3 is highly expressed in cervical cancer tissues,and its overexpression is significantly correlated with poor prognosis in patients with cervical cancer.Knockdown of circ-PHC3 upregulates the expression of miR-1179 and suppresses the proliferation,migration,and invasion of cervical cancer cells.

Objective: To investigate the effects of paeoniflorin (Pae) on acute kidney injury ( AKI) and mouse renal tubular epithelial cell ( mRTEC) damage induced by lansoprazole (LPZ) and cisplatin (CIS) through in vivo and in vitro experiments . Methods : The C57BL/6J mice or mRTECs were divided into four groups : normal control (NC) group , NC + LPZ group , CIS group , and CIS + LPZ group . Serum creatinine (CRE) and blood urea nitro- gen (BUN) levels in mice were measured , and kidney pathology was observed with HE staining. Western blot , im- munohistochemistry , and immunofluorescence were used to detect the expression levels of kidney injury molecule-1 (KIM-1) and receptor-interacting protein kinase (RIPK) 1 , RIPK3 , and mixed lineage kinase domain-like protein (MLKL) . Subsequently , C57BL/6J mice or mRTECs were divided into six groups : NC group , NC + Pae group , CIS + LPZ (M) group , and CIS + LPZ + Pae ( M + Pae) group . Serum CRE and BUN levels in each group were measured , kidney pathology was observed with HE staining , and ultrastructural changes in the kidney were observed with transmission electron microscopy. The KIM-1 and necroptosis-related protein expression levels were detected by Western blot , immunohistochemistry , and immunofluorescence . Results: Compared with the NC group , CRE and BUN levels were elevated in the CIS group , and these levels were further increased after LPZ in- tervention (all P < 0. 001) . Compared with the CIS group , renal tubular dilation and brush border loss were evi- dent in the CIS + LPZ group based on HE staining of kidney tissue (P < 0. 001) . Compared with the NC group , the expression levels of KIM-1 , RIPK1 , RIPK3 , and MLKL in the renal tissues of mice in the CIS group increased ( all P < 0. 001) , and compared with the CIS group , The expression levels of KIM-1 , RIPK1 , RIPK3 and MLKL in the renal tissues of mice in the CIS + LPZ group increased (all P < 0. 001) . After Pae treatment , compared with group M , the expression levels of CRE , BUN , KIM-1 , RIPK1 , RIPK3 and MLKL in each group of mice decreased significantly and in a dose-dependent manner (all P < 0. 001) . Conclusion LPZ promotes CIS-induced AKI by enhancing necroptosis in renal tubular epithelial cells , and Pae can improve CIS and LPZ-induced AKI by inhibi- ting necroptosis .
