Objective:To investigate the effects of thoracolumbar vertebral fracture with incomplete spinal cord injury on male sexual function and postoperative prognosis.Methods:A retrospective review was conducted on data from 144 male patients with thoracolumbar vertebral fractures and incomplete spinal cord injuries treated between May 2009 and May 2021 in the Department of Traumatology and Orthopedics at Peking University Third Hospital. Patients ranged in age from 19 to 55 years (mean: 38.6±10.6 years) and underwent posterior incision and reduction internal fixation. The International Index of Erectile Function-5 (IIEF-5), the Premature Ejaculation Diagnostic Tool (PEDT), and the International Spinal Cord Injury Male Sexual Function Basic Data Set were used for sexual function evaluation. Based on the American Spinal Injury Association (ASIA) Spinal Cord Injury classification, changes in neurological and sexual function were assessed at the pre-injury stage, 3 months post-injury, 2 years postoperatively, and at the final follow-up. Factors influencing sexual dysfunction and recovery were analyzed. Spearman correlation analysis was used to identify factors affecting sexual function injury and recovery.Results:A total of 117 patients were included in the final analysis. Follow-up duration ranged from 26.2 to 161.7 months (mean: 74.6±40.5 months). After injury, ASIA grades were distributed as follows: 43 patients with grade B, 41 with grade C, and 33 with grade D. At the 2-year follow-up, 30 patients were grade E, 63 grade D, 19 grade C, and 5 grade B. Improvement in ASIA classification was observed in 90.6% (106/117) of patients: 79 improved by one grade, 27 by two grades, 8 remained unchanged, 1 worsened by one grade, and 2 worsened by two grades. Mean IIEF-5 scores were 19.5±6.4 pre-injury, 8.7±8.0 at 3 months post-injury, and 17.5±7.1 at 2 years postoperatively, with statistically significant differences ( F=123.247, P<0.001). Differences between 3 months post-injury vs. pre-injury and 2 years postoperatively vs. 3 months post-injury were statistically significant ( P<0.05). Mean PEDT scores were 5.3±3.1 pre-injury, 6.9±5.2 at 3 months post-injury, and 6.4±5.1 at 2 years postoperatively, with statistically significant differences ( F=17.014, P<0.001). The difference between 3 months post-injury and pre-injury was statistically significant ( P<0.05), but not between 2 years postoperatively and 3 months post-injury ( P>0.05). At the 2-year follow-up, 96 patients had their IIEF-5 classification restored to pre-injury levels, 85 restored PEDT classifications, and 83 restored both. Post-injury ASIA classification was positively correlated with a decrease in IIEF-5 score and an increase in PEDT score at 3 months post-injury ( P<0.05). Injury segment was positively correlated with the decrease in IIEF-5 score ( P<0.05). Time from injury to surgery showed a positive correlation with increased PEDT score at 3 months ( P<0.05). Post-injury ASIA grade, injury segment, time to surgery, age, intraoperative decompression, and spinal cord function recovery all showed significant correlations with changes in IIEF-5 and (or) PEDT scores at 2 years postoperatively ( P<0.05). According to the International Spinal Cord Injury Male Sexual Function Basic Data Set, the proportion of patients willing to discuss sexual issues increased from 29.9% at 3 months post-injury to 47.9% at 2 years postoperatively ( P<0.05). The proportion of patients with absent or diminished psychogenic erections remained stable (48.7% vs. 48.9%, P>0.05), while those with normal reflexive erections increased from 34.2% to 65.0% ( P<0.05). Conclusion:Thoracolumbar fractures with incomplete spinal cord injury result in reduced erectile function and increased incidence of premature ejaculation. The degree of spinal cord injury and the level of the injured segment are strongly correlated with the extent of sexual dysfunction. At the 2-year postoperative follow-up, 70.9% of patients had recovered sexual function to pre-injury levels.

BACKGROUND:The role of microRNA-214 in osteoporosis has been reported both at home and abroad,whereas the interrelationship between microRNA-214 and osteoarthritic articular cartilage and subchondral bone degeneration is unclear. OBJECTIVE:To investigate the relationship between microRNA-214 and cartilage and subchondral bone degeneration in mice with knee osteoarthritis. METHODS:Thirty C57BL/6J mice were randomly grouped:Experiment 1:sham operation group and medial meniscus destabilization group (n=3 per group) underwent hematoxylin-eosin staining and qPCR to detect changes in microRNA-214 gene expression;Experiment 2:sham operation group,medial meniscus destabilization group,medial meniscus destabilization+null-loaded adenovirus group (null-loaded group),and medial meniscus destabilization+microRNA-214 antagonist overexpression adenovirus group (antagonist group;n=6 per group). Cartilage tissues were taken from each group 4 weeks after surgery,and stained with hematoxylin-eosin,safranin O-fast green,and toluidine blue. qPCR and western blot were used to detect the expression of related factors in articular cartilage. RESULTS AND CONCLUSION:(1) In Experiment 1,hematoxylin-eosin staining results showed that cartilage degeneration was visible in the medial meniscus destabilization group compared with the sham operation group. qPCR assay results showed that microRNA-214 was expressed in all the samples,and the expression level of microRNA-214 in cartilage samples of the medial meniscus destabilization group was significantly higher than that of the sham operation group (P<0.05). (2) In Experiment 2,the results of hematoxylin-eosin staining,safranin O-fast green staining,and toluidine blue staining showed that the degree of cartilage degeneration in the antagonist group was significantly reduced compared with the medial meniscus destabilization group. Adenovirus-validated PCR assay showed that the microRNA-214 expression level in cartilage tissue was higher in the null-loaded group than in the antagonist group (P<0.05). (3) In Experiment 2,X-ray results showed typical osteoarthritis imaging changes in the medial meniscus destabilization group and null-loaded group,while the degree of degenerative joint lesions was relatively mild in the antagonist group. The results of microcomputed tomography showed that after injection of microRNA-214 antagonist,trabecular structure model index became smaller in the antagonist group,and the data were better than those of the medial meniscus destabilization group and null-loaded group. (4) In Experiment 2,western blot results showed that The relative expression levels of cartilage-associated factor type Ⅱ collagen α1,sex-determining region Y-box 9,Runt-associated transcription factor 2,and osteopontin in cartilage specimens of the medial meniscus destabilization group and the null-loaded group were lower than that in the sham operation group and the antagonist group (P<0.05),whereas the relative expression level of matrix metalloproteinase 13 was higher in the medial meniscus destabilization group and the null-loaded group than the sham operation group and the antagonist group (P<0.05). (5) In Experiment 2,PCR results indicated that the relative mRNA expression of tumor necrosis factor-α and interleukin-6 was relatively higher in the medial meniscus destabilization group and null-loaded group,but relatively lower in the antagonist group,as compared with the sham operation group (P<0.05). The relative mRNA expression of tumor necrosis factor-α and interleukin-6 was also higher in the medial meniscus destabilization group and the null-loaded group compared with the antagonist group (P<0.05). To conclude,the expression level of microRNA-214 in articular cartilage was elevated in the mouse osteoarthritis model,suggesting that the elevated expression level of microRNA-214 is closely related to osteoarthritis;and injection of microRNA-214 antagonist into the knee joint cavity of the mouse osteoarthritis model could delay articular cartilage degradation,promote subchondral bone remodeling,and ameliorate the progression of osteoarthritis.

Neutrophil extracellular traps(NETs)are fibrous web-like structures composed of decondensed chromatin and granular proteins released by neutrophils,with the ability to capture and kill bacteria.Pathogens,such as bacteria and viruses,can trigger the formation of NETs via NETosis,a type of programmed cell death that has two distinct forms:suicidal NETosis and vital NETosis.Numerous studies have found that NETs interact with immune cells in the tumor microenvironment,where they activate macrophages,promote immunosuppressive effects of myeloid-derived suppressor cells,and coat the tumor surface to prevent cytotoxic effects of CD8+T cells and natural killer cells.Recent research has identified a substantial presence of NETs in oral squamous cell carcinoma(OSCC)tissues,indicating a complex re-lationship between NETs and OSCC development.Depending on the phenotype of neutrophils,NETs may exhibit pro-tu-mor or anti-tumor effects.For instance,NETs derived from N1-type neutrophils may exert anti-tumor effects,while TGF-β-induced NETs derived from N2-type neutrophils may exert pro-carcinogenic activity,thereby contributing to the devel-opment of oral squamous metaplasia.Furthermore,NETs likely play a role in OSCC metastasis by capturing circulating tumor cells and inducing a hypercoagulable state,thereby facilitating tumor-related thrombus formation and hematoge-nous metastasis.The involvement of NETs in the occurrence and progression of OSCC opens new avenues for anti-tumor therapy and prognostication.Inhibiting NET formation can significantly suppress the development of chemotherapy-in-duced drug resistance and reduce the risk of thrombosis in OSCC patients,thereby inhibiting tumor metastasis.Current-ly,multiple prognostic models based on NET-related genes have been constructed and validated for head and neck squa-mous cell carcinoma,indicating the potential clinical value of NETs.However,the association between NETs and OSCC treatment is still unclear,necessitating further research on its underlying mechanisms and feasibility.This article attempts to review the relationship between NETs and OSCC,aiming to provide novel perspectives for OSCC treatment.
