Objective To explore the safety and feasibility of mechanical thrombectomy as the first-line endovascular strategy in patients with non-acute symptomatic long-segment internal carotid artery occlusion(ICAO)undergoing revascularization.Methods This study retrospectively and consecutively enrolled non-acute symptomatic long-segment ICAO patients treated in the Department of Neurology,First Hospital of Jilin University,between January 2019 and August 2023,with mechanical thrombectomy as the preferred endovascular modality.Baseline and clinical data were collected,including sex,age,stroke-related risk factors(hypertension,diabetes,dyslipidemia,coronary artery disease,prior stroke,smoking and alcohol use history),admission National Institutes of Health stroke scale(NIHSS)score,pre-operative modified Rankin scale(mRS)score,time from last symptom onset to femoral puncture,time from imaging confirmation to femoral puncture,high-resolution MRI,right-sided ICAO,stump morphology(absent,tapered,flat/blunt,irregular),distal backfilling patterns(above ophthalmic segment,cavernous/clinoid segment,below cavernous segment),pathogenesis(atherosclerosis,dissection),types of anesthesia(local,general),procedure time(time frame from femoral puncture to recanalization or final angiography),site of the original occlusion in successfully recanalized cases,surgical techniques(aspiration+balloon angioplasty,aspiration+balloon angioplasty+stent-retriever thrombectomy,aspiration+balloon angioplasty+stent placement,aspiration+balloon angioplasty+stent-retriever thrombectomy+stent placement),stent placement(yes/no),number of stents implanted,and number of cases with retrieved thrombus,observed indicators.Observed indicators including ratio of technical successful recanalization(immediately post-procedure most severely stenosed site stenosis rate<50%,expanded thrombolysis in cerebral infarction[eTICI]grade≥2c),intraoperative complications(distal embolization,symptomatic intracranial hemorrhage,arterial perforation)rate,perioperative mortality rate,30-day stroke recurrence,and 90-day mRS score.Compare the baseline data,clinical data and observational indicators of the patients with successful and unsuccessful recanalization.Base on the original occlusion site,successfully recanalized patients were subclassified into isolated extracranial,isolated intracranial,and tandem lesions patients,and their baseline characteristics and observation indicators were compared.Results(1)A total of 65 patients were enrolled(57 men,8 women;age 39-80 years;median 59[52,65]years)in this study.Technical success was achieved in 52cases(80%).Perioperative complications occurred in 4 patients(6.2%),with 3 distal embolization cases(4.6%),1(1.5%)developed symptomatic intracranial hemorrhage,and no arterial perforations were observed.There was no perioperative mortality.The 30-day stroke recurrence rate was 7.7%(5/65).90-day mRS scores ranged from 0 to 4,with a median of 1.0(0.0,1.5).(2)Baseline and clinical characteristics as well as outcome indicators did not differ significantly between patients with successful versus unsuccessful recanalization in the cohort undergoing mechanical thrombectomy for non-acute symptomatic long-segment intracranial carotid artery occlusion(all P>0.05).(3)Among successfully recanalized patients,17(32.7%)had isolated extracranial lesions,18(34.6%)had isolated intracranial lesions,and 17(32.7%)had tandem lesions.All cases in the extracranial lesions group had original lesion site at the origin of internal carotid artery(C1,17/17).The intracranial group most often had orginal lesion sites at the C4 segment(9/18),whereas tandem lesions predominantly involved C1 plus C4-C5(16/17).Among the three groups,patients with isolated intracranial lesions were younger(57[48,61]years vs.60[52,64],63[58,69]years,P=0.050),and had a lower proportion of right-sided ICAO(4/18 vs.11/17 vs.11/17,P=0.032),while patients with tandem lesions required a greater number of stents(2.0[1.0,2.0]vs.1.0[1.0,1.5],1.0[0.8,2.0],P=0.013).Significant differences were observed in the proportion of patients with retrieved thrombus decreased progressively from patients with isolated extracranial,isolated intracranial to tandem lesions(17/17 vs.17/18 vs.12/17,P=0.024).No significant differences were observed among lesion-site groups with respect to medical history,stump morphology,distal retrograde flow,procedural technique,procedure duration,anesthesia method,or outcome indicators(all P>0.05).Conclusions This study suggested that utilizing mechanical thrombectomy as the first-line endovascular therapy for non-acute symptomatic long-segment ICAO is safe and feasible.The original occlusive sites of non-acute symptomatic long-segment ICAO predominantly involve the cervical origin and the cavernous segment of the internal carotid artery.The conclusions of this study require further validation.

Objective:To analyze the characteristics of articles published in Chinese Journal of Trauma (hereinafter referred to as the "Journal") from 1985 to 2024, so as to provide insights for further clarifying its academic orientation and improving its quality. Methods:Data of articles published from 1985 to 2024 in the Journal were retrieved and extracted from the Wanfang Database (retrieval cut-off date: April 10, 2025). Statistical analysis was performed on the publication count, total citation frequency, number of cited articles, number of highly cited articles, proportion of fund-supported articles and their citation rate, distribution of article categories, author distribution, and keyword frequency.Results:Over the 40-year period, the Journal published a total of 10 687 articles, with the total citation frequency of 45 242. Among them, 7 497 articles (70.15%) were cited and 389 (3.64%) were highly cited. A total of 2450 articles (22.93%) were supported by research funds, with a citation rate of 80.29%. The clinical researoh column showed the largest number of publications, accounting for 7 996 articles (74.82%). First authors were distributed across 31 provincial-level regions, contributing 5 878 articles and 29 583 total citations. Thirty-five corresponding authors published more than 30 articles each, 17 of whom were from medical institutions in Chongqing Municipality.

Epigenetic modifications of RNA play a crucial role in the initiation and progression of tumors.Among these modifications,N6-methyladenosine(m6A)modification catalyzed by the METTL3 methyltransferase is one of the most common RNA modifications.It is essential for regulating RNA transcription,stability,and translation.At the same time,long non-coding RNAs(lncRNAs)also serve as important regulatory molecules and play a significant role in the development and progression of tumors.However,the reciprocal interaction between lncRNAs and METTL3,as well as their functional mechanisms within tumors,are not fully understood.This paper aims to provide a comprehensive over-view of the mutual regulation between lncRNAs and METTL3 in tumors.The goal is to offer new insights and theoretical foundations for a better understanding of tumor pathogenesis.

With the continuous evolution of minimally invasive surgical concepts,operative techniques are progressively advancing from"minimal injury"toward"scarless"approaches.Super-minimally laparoscopic surgery(SMLS)is a novel surgical modality developed on the basis of conventional laparoscopic techniques through the innovation and recombination of operative elements,aiming to achieve smaller trauma and improved cosmetic outcomes.Utilizing the umbilical skin fold as a natural scar-concealing site,SMLS establishes no more than two primary operating channels(maximum diameter≤15 mm),supplemented by auxiliary ports≤2 mm in diameter on the abdominal wall.Combined with innovative separable surgical instruments and high-definition visualization systems,this approach provides a systematic solution to key issues such as residual access-site scarring.This review summarizes the development,technical innovations,current clinical applications,and potential aesthetic value of SMLS in the evolution of minimally invasive surgery,aiming to offer theoretical insights and research reference for its future promotion and technical refinement.
