Objective:To analyze the characteristics of highly cited articles on spine and spinal cord injuries published in Chinese Journal of Trauma (hereinafter referred to as the "Journal") from 1985 to 2024. Methods:All the articles related to spine and spinal cord injuries published in the Journal from 1985 to 2024 were retrieved from the Wanfang Database and the articles with citation frequency ≥15 times were defined as highly cited, with the retrieval cut-off date of April 15, 2025. For articles related to spine and spinal cord injuries, the total publication count, number of cited articles, total citation frequency, average citation frequency per article, number of fund-supported articles were recorded and analyzed. For the highly cited articles among them, the total number of articles, types of literature, distribution periods, number of fund-supported articles, core authors, institution distribution, region distribution, frequency of and key words were also statistically analyzed.Results:From 1985 to 2024, the Journal published 1 182 articles on spinal and spinal cord injuries, of which 993 (84.01%) were cited, with a total citation frequency of 10 739 and an average of 10.81 citations per article. A total of 388 articles (32.83%) were supported by research funds. There were 184 highly cited articles on spinal and spinal cord injuries, with the following characteristics: (1) The most common type of highly cited literature was original articles (150 articles, 81.52%), while consensus and guideline articles achieved the highest average citation rate (44.75 citations per article). (2) The period 2015-2019 had the highest number of highly cited articles, accounting for 33.70%. (3) Fifty-four highly cited articles (29.35%) were supported by research funds, including 19 by national-level funds and 35 by funds of other levels. (4) Among the highly cited articles, 8 (4.35%) were authored by one person, and 176 (95.65%) were co-authored by two or more persons. Sixty-two authors who published ≥3 highly cited articles were identified as core authors. (5) A total of 123 highly cited articles (66.85%) were authored by researchers affiliated with a single institution, whereas 61 articles (33.15%) were the result of inter-institutional collaboration. Fifteen first-author institutions published≥3 highly cited articles. (6) Regions with ≥15 highly cited articles were Zhejiang Province (28 articles), Chongqing Municipality (23 articles), Guangdong Province (18 articles), Shaanxi Province (18 articles), Jiangsu Province (16 articles), and Shanghai Municipality (15 articles). (7) The top five key words in the highly cited articles were "spinal fractures" (71 times), "thoracic vertebrae" (45 times), "lumbar vertebrae" (44 times), "spinal cord injuries" (27 times), and "vertebroplasty" (27 times).Conclusions:Over the 40-year period, original articles constitute the majority of highly cited articles on spine and spinal cord injuries in the Journal, while consensus and guideline articles demonstrate the highest average citation frequency. Nearly 30% of the highly cited articles receive research funding support. Core authors and institutions show a relatively concentrated distribution, with spinal fractures, spinal cord injuries, and vertebroplasty emerging as research hotspots in the field.

For middle-aged and elderly patients with conditions such as spinal fractures and degenerative spinal diseases, spinal internal fixation is a core surgical procedure for reconstructing spinal stability, heavily relying on the biomechanical stability provided by pedicle screw systems. Whereas, these patients are often complicated by osteoporosis that can significantly compromise the stability of the bone-pedicle screw interface, leading to a marked increase in pedicle screw loosening and surgical failure rates. The bone cement-augmented pedicle screw technique, which involves injecting bone cement into the vertebral body or screw trajectory to optimize the mechanical properties of the bone-pedicle screw composite, has been proven to significantly enhance fixation strength and effectively prevent screw-related failures, thereby reducing the incidence of internal fixation failure in high-risk populations undergoing spinal fusion. However, the widespread clinical application of this technique has faced challenges such as inaccurate clinical decision-making (indication and contraindication selection), non-standardized operative practices, and insufficient awareness of complication prevention, resulting in considerable variability in clinical outcomes and even severe complications. To address this, Prof. Luo Fei from First Affiliated Hospital of Army Medical University initiated the project and the Chinese Association Orthopaedic Surgeons organized relevant experts to develop the Evidence-based clinical practice guideline for bone cement-augmented pedicle screw technique ( version 2025), based on current evidence. The guidelines put forward 8 recommendations regarding the clinical value, scope of application, and operational standards of the technique, aiming to provide evidence-based medical support and technical standardization for clinical decision-making.

Chinese scientists have successfully developed two live attenuated vaccines for Japanese encephalitis (JE) using the SA14 strain of the Japanese encephalitis virus as the parent virus: the SA14-14-2 strain and the SA14-2-8 strain. The former has been widely publicized for its successful use in preventing and controlling JE in humans, while the latter′s success in immunizing hundreds of thousands of horses is less well-known. The successful result of large-scale immunization of large mammals with the SA14-2-8 attenuated strain provide scientific data for the use of live attenuated vaccines for JE in humans, which is of significant importance. This paper introduces the attenuation process of the SA14-2-8 strain and its large-scale immunization in horses, in commemoration of the contributions made by the older generation of virologists to the study of virology and vaccinology in China. It also offers insights into the technical routes for developing live attenuated vaccines for arboviruses, as the attenuation pathway and technical route of the SA14-2-8 strain differ completely from those of SA14-14-2.

The Culex tritaeniorhynchus mosquito and pigs are well-known as the primary vectors and amplification hosts of the Japanese encephalitis virus (JEV), a fact that has become common knowledge in the field of virology and infectious disease. However, 70 years ago, researchers in China and other countries isolated the JEV from various species of mosquitoes and different animal specimens, leading to no consensus on which mosquito is the main vector for JEV and which mammal serves as its principal amplification host. Since the 1950s, a research team led by Professor Wang Yimin from Institute of Virology, the Chinese Academy of Medical Sciences, collaborated with local epidemic prevention departments to investigate the vectors and host animals of JEV in China. Through extensive field and laboratory investigation, they conclusively identified the Culex tritaeniorhynchus mosquito and pigs as the primary vectors and amplification hosts for the JEV. The research findings provided strong scientific evidence for the prevention and control of Japanese encephalitis and were at the forefront or advanced level internationally at that time. This article presents the main research result of this project, offering insights into historical facts regarding the prevention and control of JEV in China, while also commemorating the significant contributions made by the pioneers of virology in our country towards the prevention and control of JE.

To investigate the role of the DPP4-nestin axis in liver fibrosis induced by alveolar cyst infection,a murine model was established using C57BL/6 mice via hepatic portal vein injection.Liver histopathological changes were assessed using HE staining,while immunohistochemistry and immunofluorescence were employed to evaluate the expression levels of nestin and DPP4 in infected mouse livers.In vitro,J S1 cell line was stimulated with recombinant DPP4 protein to es-tablish a cellular model,and qPCR,Western blot,and shRNA lentivirus interference techniques were utilized to examine the involvement of the DPP4-nestin axis in hepatic stellate cell activation.The findings demonstrated that compared to the Sham group,liver tissue structure disruption and collagen deposition were evident along with significantly increased expressions of nestin and DPP4(P＜0.050 0),which colocalized with nesin and α-SMA.Furthermore,stimulation with recombi-nant DPP4 protein significantly enhanced JS1 cell activation(P＜0.050 0)as well as upregulated nestin expression(P＜0.050 0)when compared to control group cells.Notably,shRNA lentivirus-mediated inhibition of nestin expression effectively suppressed the activating effects exerted by re-combinant DPP4 protein on JS1 cells(P＜0.050 0).Collectively,these results highlight the crucial regulatory role played by the DPP4-nestin axis in hepatic stellate cell activation triggered by alveo-lar infection;thus,targeting this axis may represent a novel therapeutic strategy for treating alveo-lar infection-induced liver fibrosis.

Objective To explore the effect of hypoxia-inducible factor-1α(HIF-1α)inhibitor LW6 on ferroptosis in septic cardiomyopathy rats.Methods Rat septic cardiomyopathy model was prepared using cecal ligation and puncture(CLP)method.Thirty-six specific pathogen-free(SPF)6-8 weeks male SD rats were randomly divided into the sham-operated group,CLP group,CLP+solvent group,LW6 group,ferrostatin-1(Fer-1)group,and LW6+Fer-1 group.The degree of myocardial damage in each group was evaluated through hematoxylin-eosin stai-ning and detection of lactate dehydrogenase and creatine kinase content in cardiac tissue.Myocardial mitochondrial damage was observed by transmission electron microscopy.Ferroptosis level was determined by detecting iron ion concentration,reduced glutathione,malondialdehyde,and reactive oxygen species.Protein expression levels of HIF-1α,solute carrier family 7 member 11(SLC7A11),and glutathione peroxidase 4(GPX4)in cardiac tissue were detected by Western blotting.Results Compared with the CLP group and the CLP+solvent group,the LW6 group could ameliorate myocardial damage,alleviate mitochondrial damage,inhibit ferroptosis-related indicators(all P＜0.05),reduce HIF-1α protein expression levels(P＜0.05),and enhance SLC7A11 and GPX4 protein expression levels(both P＜0.05).Conclusion LW6 decreases HIF-1α expression and ferroptosis levels through the SLC7A11/GPX4 pathway,and ameliorates sepsis-induced cardiomyopathy.

The floating thrombus in the brachiocephalic artery is relatively rare and difficult to diagnose,and it is prone to be missed.This article reports a case of a patient with a floating thrombus in the brachiocephalic artery who underwent endovascular treatment via a combined radial artery and femoral artery approach.The patient presented with slurred speech,weakness in the left limbs,and dizziness.A cranial DWI examination revealed acute cerebral infarction in the right cerebral hemisphere and bilateral cerebellum.A neck CTA examination showed a floating thrombus in the brachiocephalic artery.Currently,there is no consensus on the treatment of floating thrombi in the brachiocephalic artery.The effect of conservative medical treatment for this patient was poor,and endovascular treatment was administered.The vertebral artery and carotid artery protection umbrellas were deployed via the radial artery approach to prevent intraoperative embolism events.A stent was deployed via the femoral artery approach to adhere to the thrombus.A follow-up neck CTA examination of the patient after the operation indicated that the stent was in a good position with complete thrombus apposition.

Objective:To investigate the efficacy of blepharoplasty using the "double-line technique" in addressing upper eyelid skin laxity in middle-aged and elderly patients.Methods:A retrospective analysis was conducted on the clinical data of middle-aged and elderly patients with moderate to severe upper eyelid skin laxity who were admitted to the Plastic Surgery Department of Shaanxi Provincial People’s Hospital between January 2020 and January 2023. The same surgeon performed the "double-line" blepharoplasty to excise excess upper eyelid skin for laxity correction. Patients were positioned flat with their eyes closed; an arcuate line a (5-7 mm above the pupil) and a second line b (aligned with the eyelid margin in an upright position) were marked. The skin between these two lines was excised. Postoperatively, the double eyelid shape, improvement in skin laxity, adverse reactions, and patient satisfaction (categorized as satisfied, basically satisfied, unsatisfied) were assessed.Results:A total of 145 patients were included in the study, comprising 27 males and 118 females. Their ages ranged from 38 to 78 years, with an average age of 52 years. All patients’ incisions healed primarily without complications such as hematoma and infection. During the 3 to 12 months of follow-up after surgery, the double eyelid arcs on both sides appeared symmetrical and natural. The upper eyelid laxity was effectively corrected, obscured vision was improved, crow’s feet were reduced, and the periorbital area was rejuvenated. Patient satisfaction with the surgical results was high, with 112 patients reporting satisfaction, 25 reporting basically satisfied, and 8 reporting dissatisfaction. The overall satisfaction rate reached 94.48%(137/145). Among those dissatisfied, 6 cases cited the double eyelid crease as being too narrow, and 2 cases noted asymmetry in the double eyelid crease.Conclusion:The "double-line method" for blepharoplasty is straightforward to perform and effectively removes excess upper eyelid skin. It is suitable for middle-aged and elderly patients with moderate to severe upper eyelid skin laxity, resulting in favorable surgical outcomes.
