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:To investigate the clinical features and predictive indicators of children with recurrent simple febrile seizures, providing theoretical guidance for the early identification of such patients in clinical practice.Methods:This study is a single-center, retrospective analysis. It included 152 children with febrile seizures who were admitted to Department of Emergency, Hangzhou Children's Hospital from January 2021 to December 2023. Based on whether multiple episodes of simple febrile seizures occurred within 24 hours, the children were divided into a recurrent simple febrile seizure group ( n = 44) and a simple febrile seizure group ( n = 108). Demographic characteristics, clinical data, and laboratory test results were collected. Statistical analysis was performed using univariate and multivariate logistic regression, correlation analysis, and receiver operating characteristic curves. Results:Among the 152 children with febrile seizures included in this study, 44 (28.95%) were diagnosed with recurrent simple febrile seizures. Children with recurrent simple febrile seizures had lower temperatures upon admission, were younger at the time of their first febrile seizure, and had a higher proportion of cases where the time interval from fever to seizure was < 12 hours ( t = 2.84, 4.25, 8.45, all P < 0.05). Pearson correlation analysis showed that recurrent simple febrile seizures were negatively correlated with admission temperature and age at first febrile seizure ( r = -0.599, -0.609, both P < 0.001) and positively correlated with the time interval from fever to seizure ( r = 0.568, P = 0.004). Logistic regression analysis indicated that age at first febrile seizure and a time interval from fever to seizure of ≥ 12 hours were influential factors of recurrent simple febrile seizures ( OR = 2.864, 2.145, P = 0.004, 0.007). Receiver operating characteristic curve analysis revealed that admission temperature, age at first febrile seizure, a time interval from fever to seizure of ≥ 12 hours, and their combination were all effective in detecting recurrent simple febrile seizures. However, the combined assessment had higher sensitivity and specificity than any single assessment, with a sensitivity of 88.60%, specificity of 89.80%, a cutoff value of 0.840, and an area under the curve of 0.886. Conclusions:Lower admission temperatures, younger age at the time of the first febrile seizure, and a time interval of < 12 hours from fever to seizure are associated with an increased likelihood of simple febrile seizures developing into recurrent simple febrile seizures.

Objective To investigate the effect of forsythigenin on the malignant progression of lung cancer cells by regulating the cyclic adenosine monophosphate/exchange protein directly activated by cAMP1/Ras-associated protein 1(cAMP/EPAC1/RAP1)signaling pathway.Methods Lung cancer cell line A549 was cultured in vitro and grouped into the control group,the low dose forsythigenin group(25 mg/L),the medium dose forsythigenin group(50 mg/L),the high dose forsythigenin group(100 mg/L),the high dose forsythigenin+specific increase in intracellular cAMP content(pertussis toxin PTX)group(100 mg/L forsythigenin+5 μmol/L PTX)and high dose forsythigenin+EPAC1 antagonist(ESI-09)group(100 mg/L forsythigenin+1.5 μmol/L ESI-09).CCK-8 experiment was applied to detect cell proliferation.Scratch test was applied to detect cell migration.Flow cytometry was applied to detect cell apoptosis.Transwell was applied to detect cell invasion.ELISA method was applied to detect cAMP level in cell supernatant.Western blot assay was applied to detect expression levels of cAMP/EPAC1/RAP1 signaling pathway proteins and apoptotic proteins[B lymphoblastoma-2(Bcl-2)and Bcl-2 associated X protein(Bax)].Results Compared with the control group,the OD450 value of A549 cells,number of cell invasions,scratch healing rate,level of cAMP,expression levels of Bcl-2,EPAC1 and RAP1 proteins were significantly reduced in the low dose,medium dose and high dose forsythigenin groups,and the expression of Bax protein and the rate of cell apoptosis were significantly increased in a dose-dependent manner(P＜0.05).Compared with the high-dose forsythigenin group,the OD450 value of A549 cells,scratch healing rate,number of cell invasions,level of cAMP,expression levels of Bcl-2,EPAC1 and RAP1 proteins were obviously increased in the high-dose forsythigenin+PTX group,the expression of Bax protein and the apoptosis rate were obviously reduced(P＜0.05).Levels of all indexes in the high dose forsythigenin+ESI-09 group were opposite.Conclusion Forsythigenin inhibits proliferation,migration,and invasion of A549 cells and promotes apoptosis by down-regulating the cAMP/EPAC1/RAP1 signaling pathway.

Objective To explore the clinical efficacy of different mucosal incision methods in endoscopic submucosal dissection(ESD)for the treatment of gastric submucosal tumors.Methods A retrospective analysis was conducted on the clinical data of 30 patients with gastric submucosal tumors treated with ESD from July 2022 to March 2024.They were divided into a circular group(n=15)and a longitudinal group(n=15)based on different mucosal incision methods.Then compare the pathological data,clinical efficacy,surgical outcomes,and complications between the two groups.Results There were no statistically significant differences between the two groups in length of hospital stay,hospitalization costs,lesion diameter,lesion location and lesion nature(P＞0.05).The surgical time of the longitudinal group was significantly shorter than that of the circular group,and the difference was statistically significant(P＜0.05);There was no statistical significant in the incidence of intraoperative complications in the longitudinal group and the circular group(P＞0.05);The complete resection rate of the longitudinal group was lower than that of the circular group,but the difference was not statistically significant(P＞0.05).Conclusion ESD treatment for gastric submucosal tumors is safe and effective,and the longitudinal incision can shorten the surgical time compared to the circular incision.Both methods have the characteristics of low incidence of complications and high complete resection rate,and are worthy of clinical application.

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: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.
