Objective:To evaluate the clinical efficacy of transoral robotic surgery (TORS) in the treatment of malignant tongue base tumors.Methods:A multicenter study was conducted to collect and analyze the clinical data of patients with malignant tongue base tumors who underwent TORS at five otolaryngology-head and neck surgery centers in China, including Eye Ear Nose and Throat Hospital of Fudan University, Sun Yat-sen University Cancer Center, Tongji Hospital of Huazhong University of Science and Technology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, and the First Affiliated Hospital of China Medical University between January 2017 and January 2023. Among the patients, 38 were males and 11 were females, with a mean age of 59.0±8.8 years. Baseline characteristics, complications, and follow-up data were compared between groups. Independent sample t-tests or Mann-Whitney U tests was used for comparisons of continuous variables; chi-square tests or Fisher′s exact tests was applied for categorical variables. Survival analysis was performed using the Kaplan-Meier method to calculate overall survival and disease-free survival, and differences between groups were compared using the log-rank test. Results:Among the 49 patients, 41 (83.7%) were diagnosed with squamous cell carcinoma (SCC), with a p16 positive rate of 51.2% (21/41). There were no statistically significant differences between the p16-positive group ( n=21) and the p16-negative group ( n=20) in age, sex, or postoperative bleeding (all P>0.05). However, there was a significant difference in TNM stage between the two groups ( χ2=14.556, P=0.020), with the p16-positive group predominantly in stage I (66.7%) and the p16-negative group primarily in stages Ⅲ and Ⅳ (40.0% and 30.0%, respectively). The postoperative tracheotomy rate was 30.6% (15/49), and the incidence of postoperative bleeding was 6.1% (3/49). The 1-year and 3-year overall survival rates were 98.0% and 92.5%, respectively, while, the 1-year and 3-year disease-free survival rates were 89.2% and 84.9%, respectively. No significant differences were observed between the p16-positive and p16-negative groups in 3-year overall survival (100% vs. 83.8%, χ2=1.093, P=0.518) or 3-year disease-free survival (68.2% vs. 88.9%, χ2=2.161, P=0.382). Conclusion:TORS for malignant tongue base tumors demonstrates high clinical safety and favorable oncological outcomes.

Objective:To investigate the efficacy and feasibility of transoral robotic surgery (TORS) for resection of tumors in the parapharyngeal spaces.Methods:The clinical data of 57 patients who underwent TORS for parapharyngeal space tumors from September 2018 to February 2024 were retrospectively analyzed. These patients were treated at five medical institutions: The First Affiliated Hospital of China Medical University, Eye & ENT Hospital of Fudan University, Sun Yat-sen Memorial Hospital, Sun Yat-sen University, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, and Sun Yat-sen University Cancer Center. The patients were 28 males and 29 females, aged 17-77 years (median age, 47 years). The pathological types, locations, and sizes of the tumors, operation time, intraoperative bleeding volumes, postoperative hospital stays, and postoperative complications were evaluated. The data were analyzed using SPSS 27.0 software.Results:Postoperative pathological examination revealed 11 types of benign tumors. Among 57 cases, 27 cases had their tumors in the prestyloid spaces, predominantly with pleomorphic adenoma ( n=17), and 30 cases in the retrostyloid spaces, predominantly with schwannoma ( n=22). The tumor volumes ranged from 0.6 to 130.1 cm3, the intraoperative bleeding volumes ranged from 5 to 1 000 ml, the operation time ranged from 20 to 390 min, and the postoperative hospital stays ranged from 2 to 25 days. The total costs for individual cases were 36 000-100 000 yuan, with the highest cost in the case suffering from cerebrovascular accident. Four patients(7.0%) had tracheotomy and 36(63.2%) had nasogastric tube placement. Among the 57 patients, 5 had postoperative cavity effusion, 2 had wound dehiscence, 2 had cerebrovascular accidents, 1 had Horner syndrome, and 2 had other complications. The patients were followed up for 1-67 months, with only 1 patient with intracranial and extracranial communication relapsed. Conclusion:TORS is a safe and feasible approach for treating parapharyngeal space tumors, offering advantages such as minimal invasiveness, reduced blood loss, and faster recovery. It is suitable for parapharyngeal space tumors of various pathological types and locations. The postoperative complications are manageable, with favorable long-term follow-up results and low recurrence rates.

Objective:Based on bioinformatics analysis, this study aimed to identify the complement component 5a receptor 1(C5aR1)and chemokine C-C motif ligand-2(CCL2)genes in vascular dementia(VaD)and to explore the expression and clinical significance of serum C5aR1 and CCL2 levels in VaD patients.Methods:The GSE122063 dataset was selected from the Gene Expression Omnibus(GEO)database to screen for consistently differentially expressed genes in the frontal and temporal lobes of VaD patients and non-dementia patients.The Matascape database was used to analyze the functions and pathways of differentially expressed genes, and the STRING network and Cytoscape software were used to identify key genes.In this case-control study, 53 VaD patients seeking care at the Department of Neurology of the Affiliated Hospital of Jiangsu University between January 2022 and December 2022 were included in the VaD group, and 50 non-dementia individuals were included in the control group.General information, Montreal Cognitive Assessment(MoCA)scores, Mini-Mental State Examination(MMSE)scores, and scores of the total cerebral small vessel disease(CSVD)burden were collected for both groups, and serum C5aR1 and CCL2 expression was detected.The correlation of serum C5aR1 and CCL2 levels with MoCA scores, MMSE scores, and scores of the total CSVD burden in the VaD group was analyzed.Receiver operating characteristic(ROC)curve analysis was used to assess the diagnostic value of serum C5aR1 and CCL2 levels in VaD.Results:In the GSE122063 dataset, compared with non-dementia patients, there were 43 upregulated genes and 63 downregulated genes simultaneously in the frontal and temporal lobes in the VaD group.After importing 106 genes into the Cytoscape software and using the Stress and Betweenness algorithms in the cytoHubba plugin, two key genes, C5aR1 and CCL2, were identified.Serum levels of C5aR1[(57.25±10.34)μg/L vs.(43.26±8.24)μg/L, t=7.607, P<0.001]and CCL2[(210.42±42.19)ng/L vs.(151.73±36.04)ng/L, t=7.570, P<0.001]in the VaD group were higher than those in the control group.Serum levels of C5aR1 and CCL2 were negatively correlated with MoCA scores( r=-0.691, -0.668, P<0.001)and MMSE scores( r=-0.736, -0.729, P<0.001), and positively correlated with scores of the total CSVD burden( r=0.598, 0.582, P<0.001).The areas under the ROC curve for serum C5aR1 and CCL2 levels in diagnosing VaD was 0.838 and 0.845, respectively.The area under the ROC curve with the combination of C5aR1 and CCL2 for the diagnosis of VaD was 0.896. Conclusions:Serum levels of C5aR1 and CCL2 are elevated in VaD patients and closely related to their cognitive function and the total CSVD burden, and may be used as an auxiliary diagnostic tool for VaD patients.

[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

Objective:To investigate the application and clinical efficacy of customized, 3D-printed femoral bone marrow stems in the revision of tumor prostheses.Methods:A retrospective analysis was performed for the data of 11 patients (7 males and 4 females) aged 53.1±11.7 years (range, 38-75 years), who underwent 3D-printed customized revision of femoral intramedullary stems due to loosening of femoral tumor prostheses at the 960th Hospital of the Joint Support Force of the PLA from June 2021 to June 2023. The pathological types of tumors associated with the initial surgeries included 4 cases of giant cell tumor of bone, 5 cases of osteosarcoma, 1 case of chondrosarcoma, and 1 case of plasma cell tumor. The tumor was located at the distal femur in 8 cases and the proximal femur in 3 cases. The procedures included 3 initial revisions, 7 secondary revisions, and 1 tertiary revision. The average limb shortening measured 4.6±2.2 cm (range, 2.5-9.0 cm). Prior to revision, all prostheses were fixed with bone cement, revealing enlargement of the femoral medullary cavity and cortical bone thinning. Among them, 5 cases had intramedullary stems permeabilizing the femoral cortex, and 1 case had femoral cleavage fractures. All 11 patients received personalized data for the design and 3D printing of femoral bone marrow stems.Results:The lengths and diameters of the 3D-printed porous femoral bone marrow stems ranged from 80 to 160 mm and 20 to 22 mm, respectively. Ten patients were fitted with cylindrical intramedullary handles, while one received a conical intramedullary handle. A successful revision with the 3D-printed stems was achieved in 10 patients; however, 1 case failed to accommodate the conical handle and was instead revised with a bone cement prosthesis. During the implantation of the intramedullary stems, three patients experienced minor cortical splitting, which was managed with bundling and fixation during the procedure. Immediate stability was attained for all prostheses during surgery, yet postoperative limb shortening did not undergo significant correction. All patients exhibited normal healing of their postoperative incisions. The visual analog scale for limb pain decreased significantly from 8.0±0.8 points before surgery to 1.0±0.4 points three months postoperatively ( t=25.957, P<0.001). By six months after the surgery, none of the patients reported any limb pain. Follow-up data for all 11 patients indicated an average follow-up duration of 25.2±7.5 months (range, 16-36 months), during which limb function improved satisfactorily. The Musculoskeletal Tumor Society (MSTS) score increased from 7.9±1.4 points preoperatively to 20.9±2.7 points at the last follow-up, with this change also being statistically significant ( t=14.229, P<0.001). Imaging evaluations revealed normal lower limb force lines, no rotation or longitudinal displacement of the prosthetic stem, and successful integration with the femur. Conclusion:Personalized intramedullary stems produced through 3D printing demonstrate significant clinical effectiveness in femoral tumor prosthesis revision surgery, making them a viable option for such procedures.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

OBJECTIVE: To investigate the expression and potential mechanism of calcium/calmodulin-dependent protein kinase II gamma (CaMKIIγ) in patients with acute myeloid leukemia (AML). METHODS: Peripheral blood samples were collected from 90 AML patients, and mononuclear cells were isolated. The expression of CaMKIIγ was measured using real-time quantitative PCR and Western blot. The diagnostic value of CaMKIIγ for AML was assessed, and its correlation with clinical characteristics was analyzed using the clinical data of patients. Additionally, the molecular mechanisms of CaMKIIγ were preliminarily explored. RESULTS: Compared with the control group, the expression of CaMKIIγ was significantly upregulated in AML patients. Receiver operating characteristic (ROC) curve analysis showed that CaMKIIγ could serve as a promising biomarker for distinguishing AML patients from healthy individuals. Furthermore, CaMKIIγ was significantly correlated with white blood cell (WBC) count and FLT3-ITD mutation. CaMKIIγ was highly expressed in both newly diagnosed and relapsed AML patients, while decreased during remission. In AML cell lines, the expression levels of CaMKIIγ were all elevated. Inhibition of phosphorylated CaMKIIγ by berbamine led to a decrease in pAKT and pSTAT5 expression. CONCLUSION CaMKIIγ is significantly upregulated in AML patients, and is associated with poor clinicopathological features and unfavorable prognosis. It may serve as a prognostic marker and potential therapeutic target in AML. Its expression may be related to the activation of pAKT and pSTAT5, suggesting that CaMKIIγ may contribute to the development and progression of AML through the activation of the AKT/STAT5 signaling pathway.
