Objective To compare the cost-effectiveness between sodium valproate and levetiracetam in the treatment of childhood epilepsy and provide an economic basis for clinical medication choices. Methods A cost-effectiveness analysis was conducted using a decision tree model to compare the effectiveness and drug costs of sodium valproate and levetiracetam in treating childhood epilepsy. Single-factor sensitivity analysis and probabilistic sensitivity analysis were used to assess the impact of parameter variations on the study results. Results The treatment cost of levetiracetam was significantly higher than that of sodium valproate. The incremental cost-effectiveness ratio （ICER） of levetiracetam compared to sodium valproate was ¥8 628.43. Sensitivity analysis results were consistent with the base-case analysis. The probabilistic sensitivity analysis showed that, over a 6-month treatment period, levetiracetam became a more cost-effective option when the willingness-to-pay （WTP） threshold was ¥9,000 or higher. One-way sensitivity analysis revealed that the price of levetiracetam was the most influential factor affecting the ICER. Conclusion When the WTP per effective pediatric epilepsy case is ¥9,000 or higher, levetiracetam demonstrates a cost-effectiveness advantage.

Objective:To study the expression of the Homeobox C6(HOXC6)gene in the homeobox family in PCa,its effect on the biological behavior of PCa cells and its action mechanism.Methods:Based on the studies of HOXC6 retrieved from the data-base of Gene Expression Profiling Interactive Analysis(GEPIA),we analyzed the expression of HOXC6 in PCa and the relationship of its expression level with the survival prognosis of the patients.We detected the expression of the HOXC6 protein in PCa tissues and cells by Western blot,stably interfered with the expression of the HOXC6 gene in human PCa DU145 and PC-3 cells and normal prosta-tic epithelial RWPE-1 cells using the siRNA plasmid,and determined the effects of HOXC6 on the proliferation,migration and inva-siveness of PCa cells by CCK8,plate cloning and scratch healing and Transwell invasion assays.Using the GEPIA database,we ana-lyzed the correlation of the Wnt tumor inhibitory factor-secreted frizzled-related protein 1(SFRP1)gene with HOXC6,and detected the expressions of HOXC6,SFRP1,Wnt and β-catenin in PC-3 cells after siRNA-HOXC6 transfection by Western blot.Results:The expression of HOXC6 was dramatically higher in the PCa than in the normal prostate tissue(P<0.01),and in the PCa cells than in the normal prostatic epithelial cells(P<0.01).Bioinformatics analysis indicated a lower survival rate of the PCa patients with a high than those with a low HOXC6 expression(P=0.011).The relative expression of the HOXC6 protein,absorbance value,number of clones formed and number of invaded cells were significantly lower in the siRNA group than in the negative controls(P<0.05).Ac-cording to the GEPIA database,highly expressed SFRP1 was associated with a good prognosis of PCa,and the protein expressions of Wnt and β-catenin were markedly increased while that of SFRP1 decreased in the PCa PC-3 cell line(P<0.05).The expressions of the Wnt and β-catenin proteins were decreased and that of SFRP1 increased significantly in the siRNA-HOXC6 transfection group com-pared with those in the siRNA negative control and PCa PC-3 groups(P<0.05).Conclusion:HOXC6 is highly expressed in PCa tissues and related to the proliferation,migration and invasiveness of PCa cells.HOXC6 promotes the growth of DU145 and PC-3 cells in PCa by inhibiting the SFRP1/Wnt/β-catenin signaling pathway,and may be a potential target for clinical treatment of PCa.

Objective:To investigate the safety, feasibility and accuracy of esophageal sponge cytology in esophageal carcinoma screening in high-incidence districts.Methods:Opportunistic screening for esophageal carcinoma was conducted on individuals aged 40-75 years with high-risk factors for esophageal carcinoma and visited out-patient clinic in Lianshui People's Hospital from May 2021 to June 2022. A new esophageal cell collector independently developed in China was used for esophageal sponge cytology sampling followed by cytopathological analysis. Atypical squamous cells or more severe lesions were defined as positive esophageal sponge cytology. Then gastroscopy was performed, and all suspicious areas under the endoscopy were biopsied for histopathological examination. Gastroscopy, biopsy histopathology and esophageal sponge cytology were conducted blindly in pairs. Outcome measures included adverse reactions during sampling, subject tolerability (using a visual simulation score), sampling quality, and diagnostic efficacy of esophageal sponge cytology using gastroscopy plus biopsy histopathology as the gold standard.Results:A total of 1 590 patients completed the screening program. During esophageal sponge cytology sampling, no serious adverse events were observed, and the adverse reactions were mainly manifested as vomiting during sampling [0.31% (5/1 590)] and sore throat after sampling [2.45% (39/1 590)], all of which resolved spontaneously without further medical intervention. The majority of subjects [98.62% (1 568/1 590)] reported good tolerance during the procedure. After sampling, 1 526 (95.97%) subjects had completely expanded sponge material, meeting the standard of good sampling quality. The scanning analysis of the digital pathology system showed that the number of sampled cells in 1 590 subjects ranged (2.01-4.00)×10 6, with a median of 3.48×10 6 cells, which could meet the requirements for interpreting cytological results. Using the positive esophageal sponge cytology for the diagnosis of esophageal carcinoma including high-grade intraepithelial neoplasia, esophageal squamous cell carcinoma and adenocarcinoma of esophagogastric junction, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 98.57% (69/70), 91.51% (1 391/1 520), 34.85% (69/198), 99.93% (1 391/1 392), and 91.82% (1 460/1 590), respectively. Conclusion:Esophageal sponge cytology presents promising diagnostic efficacy for esophageal carcinoma screening, offering a simple, safe, convenient, and effective approach in high-incidence esophageal carcinoma regions.

Objective To establish and validate a ferroptosis model in human aortic vascular smooth muscle cells(HAVSMCs).Methods HAVSMCs were obtained from aortic arch tissues of donors who underwent heart transplantation at the Cardiothoracic and Vascular Surgery Department,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology.Ferroptosis was induced through imidazole ketone erastin(IKE)and cystine-deficient medium(CD)in HAVSMCs.Cell counting kit-8(CCK-8),human lactate dehydrogenase(LDH)assay kit,flow cytometry and cell immunofluores-cence staining were used to evaluate whether ferroptosis was successfully induced in HAVSMCs.Results After the induction of ferroptosis in HAVSMCs for a certain period of time,obvious morphological changes of HAVSMCs were observed under the optical microscope,and the flow cytometry analysis showed that the proportion of propidium iodide(PI)positive stained cells was significantly increased under the induction of IKE/CD.The results of CCK-8 and LDH assays showed that the cell viability of HAVSMCs was significantly reduced,and the level of cell damage was markedly increased under IKE/CD induction.Ferrostatin-1,an inhibitor of ferroptosis,was able to reverse the toxic effects of ferroptosis induction on the cells.The flow cytometry analysis of BODIPY-C11 and immunofluorescence staining of 4-hydroxynonenal(4-HNE)showed a notable increase in lipid peroxidation levels in IKE/CD-induced HAVSMCs.Conclusion In this study,a ferroptosis model was successfully established in human aor-tic vascular smooth muscle cells with IKE and cystine-deficient medium,which provided an experimental basis for subsequent researches.

Objective To analyze the risk factors and survival status of Epstein-Barr virus(EBV)infection in pa-tients with aplastic anemia(AA)after haploid allogeneic hematopoietic stem cell transplantation(Haplo-HSCT).Methods Clinical data of 78 AA patients who underwent Haplo-HSCT in the hematology department of a hospital from January 1,2019 to October 31,2022 were analyzed retrospectively.The occurrence and onset time of EBV viremia,EBV-related diseases(EBV diseases),and post-transplant lymphoproliferative disorders(PTLD)were ob-served,risk factors and survival status were analyzed.Results Among the 78 patients,38 were males and 40 were females,with a median age of 33(9-56)years old;53 patients experienced EBV reactivation,with a total inci-dence of 67.9％,and the median time for EBV reactivation was 33(13,416)days after transplantation.Among pa-tients with EBV reactivation,49 cases(62.8％)were simple EBV viremia,2 cases(2.6％)were possible EBV di-seases,and 2 cases(2.6％)were already confirmed EBV diseases(PTLD).Univariate analysis showed that age 1＜40 years old at the time of transplantation,umbilical cord blood infusion,occurrence of acute graft-versus-host disease(aGVHD)after transplantation,and concurrent cytomegalovirus(CMV)infection were independent risk fac-tors for EBV reactivation in AA patients after Haplo-HSCT.Multivariate analysis showed that concurrent CMV in-fection was an independent risk factor for EBV reactivation in A A patients after Haplo-HSCT(P=0.048).Ritu-ximab intervention before stem cell reinfusion was a factor affecting the duration of EBV reactivation(P＜0.05).The mortality of EBV viremia,EBV diseases,and PTLD alone were 8.2％,50.0％,and 100％,respectively.The 2-year overall survival rate of patients with and without EBV reactivation were 85.3％,and 90.7％,respectively,difference was not statistically significant(P=0.897).However,patients treated with rituximab had 2-year lower survival rate than those who did not use it,with a statistically significant difference(P=0.046).Conclusion EBV reactivation is one of the serious complications in AA patients after Haplo-HSCT,which affects the prognosis and survival of patients.

Purpose To establish and validate an ultrasound-based radiomics nomogram for predicting ipsilateral axillary lymph node metastasis in stage T1 breast cancer.Materials and Methods 443 stage T1 breast cancer patients in the First Affiliated Hospital of Wannan Medical College from January 2012 to June 2021 were retrospectively collected.All patients were randomly divided into training(n=310)and validation(n=133)group.ITK-SNAP was used to delineate the tumor margins,and Pyradiomics software was used to extract features.Image omics models and Rad-scores were constructed after feature screening.Clinical model,radiomics model and combined diagnostic models were developed,with the combined model's nomogram constructed.The models'predictive values were assessed via receiver operating characteristic curves.Results Multivariate Logistic regression analysis showed that the positive axillary ultrasonography,high echo halo and abundant internal blood supply were the independent risk factors of axillary lymph node metastasis.Then the clinical model was constructed,and imaging omics model was also constructed by feature screening.The combined model,which incorporated clinical and imaging features,demonstrated superior predictive performance.In the training group,the area under the curve for the combined model was 0.822,which was significantly higher than that of the clinical model(0.765)and radiomics model(0.723)(P=0.002 1,P=0.001 8).In the validation group,the area under the curve for the combined model was 0.846,outperforming the imaging omics model(0.686,P=0.001 8)and the clinical model(0.783),though the latter difference was not statistically significant(P=0.111 3).Conclusion Ultrasound-based radiomics combined diagnostic model effectively predicts ipsilateral axillary lymph node metastasis in stage T1 breast cancer,demonstrating high clinical predictive efficiency.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
