The benefit of postoperative adjuvant therapy for patients with resectable esophageal squamous cell carcinoma (ESCC) is not yet supported by high-level evidence. This review analyzes the role of adjuvant therapy by examining the discrepancy between clinical needs and guidelines, its historical evolution, recent advances in high-risk factors, and future outlooks. We provide a detailed discussion of high-risk factors used for patient selection, including lymph node positivity, and for node-negative patients, features such as tumor length, location, T stage, extent of lymph node dissection, differentiation, vascular and neural invasion, laboratory indices, and molecular markers. The goal is to inform the development of individualized precision treatment strategies for resectable ESCC.

Objective·To detect the expression level of Fas-associated protein with death domain(FADD)in head and neck squamous cell carcinoma(HNSCC)and to explore the molecular mechanisms by which FADD promotes the proliferation of HNSCC cells.Methods·The GEPIA 2 database was utilized to analyze the expression level of FADD in tumor tissues and to evaluate its association with prognosis.Immunohistochemistry staining(IHC)was performed on HNSCC tissues to investigate the changes in FADD expression levels in normal,dysplastic,and tumor tissues.Stable FADD-knockdown Fadu and HSC3 cell lines were constructed and validated using Western blotting and quantitative real-time PCR(qRT-PCR).The regulatory effect of FADD on the proliferation of HNSCC cells was explored using the LiveCyte live-cell tracking system,colony formation assay,and cell viability assay.Proteins interacting with FADD were identified by co-immunoprecipitation mass spectrometry(Co-IP/MS),and further mechanistic studies were conducted using CRISPR/Cas9 technology,LiveCyte live-cell tracking system,and Western blotting.Results·Analysis of the GEPIA2 database indicated that FADD was significantly overexpressed in head and neck cancer and was associated with poor prognosis.IHC staining showed that FADD expression levels progressively increased from normal to dysplastic to tumor tissues in HNSCC patients.Knockdown of FADD in HNSCC cells resulted in significantly reduced proliferation and colony formation compared to the control group.Co-IP/MS results showed that FADD interacted with the CUX1 protein,and FADD knockdown led to increased CUX1 expression.Moreover,CUX1 knockdown significantly promoted HNSCC cell proliferation and reversed the anti-proliferative phenotype caused by FADD knockdown.Conclusion·FADD plays a significant pro-carcinogenic role in HNSCC and is associated with poor prognosis.FADD can further regulate tumor cell proliferation by interacting with CUX1 and suppressing its expression level.

Objective:To understand the coverage and information consistency rate of National Immunization Program (NIP) vaccines among children born during 2020-2021 in Zhejiang Province, Chongqing City, and Shanxi Province (3 provinces) of China .Methods:A simple random sampling method was used to randomly select 3 counties (districts) from each of the 3 provinces, 5 townships from each county (district), and 5 villages from each township. Vaccination information for seven NIP vaccines was collected for children born between 2020 and 2021 in each village. The vaccination coverage, timely coverage, and consistency rates between the survey data and the Immunization Planning Information System data were analyzed.Results:A total of 1 117 children were investigated. The vaccination coverage for each dose of NIP vaccine ranged from 99.10% to 100.00%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 99.19% to 100.00%, 98.92% to 100.00%, and 99.20% to 100.00%, respectively. The timely coverage of each dose of NIP vaccine ranged from 89.79% to 99.82%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 94.09% to 99.73%, 89.52% to 99.73%, and 78.55% to 100.00%, respectively. The consistency rate of information on each dose of NIP vaccine ranged from 94.36% to 99.91%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 97.85% to 99.73%, 98.92% to 100.00%, and 86.06% to 100.00%, respectively.Conclusions:Coverage of NIP vaccines was generally high among children born during 2020-2021 in the 3 provinces of China, but there were regional differences in the timely coverage of some vaccine doses and the vaccination information consistency rate. It is necessary to strengthen the timely vaccination of children's vaccine booster doses and optimize the management of vaccination services.

With the progress of medical insurance reform,the refinement of medical insurance management in pub-lic hospitals still fails to meet the actual demands for medical insurance work.Based on the existing problems of medical insurance management,it emphasizes the necessity of the refined management of medical insurance.By integrating be-havioral economics theory,it divides the refined management of medical insurance into five distinct stages:develop-ment planning,process-oriented platform,organizational framework,staff training programs and regulatory supervi-sion.The behavioral logic of the refined management of medical insurance in public hospitals is analyzed.Building on this analysis,the relevant key insights are summarized to provide a reference for promoting the public welfare-oriented reform of public hospitals and realizing the high-quality development of public hospitals.

This study reported two cases of distal 18q deletions identified through non-invasive prenatal testing (NIPT). Case 1 harbored a de novo 20.4 Mb deletion of 46, XY, del(18) (q21.32q23), classified as pathogenic according to the American College of Medical Genetics and Genomics (ACMG) guidelines. Follow-up at five years of age revealed global developmental delay, congenital heart disease, and distinct facial features. Case 2 had a 5.71 Mb paternal-origin deletion of 46,XX,del(18)(q22.1q22.2), with only mild tricuspid regurgitation detected at eight months of age. These phenotypic discrepancies demonstrated that the clinical manifestations of 18q deletion syndrome were closely associated with the size of the deleted segment and the involved critical genes. Therefore, individualized genetic counseling and long-term follow-up were necessary for the affected children.

Objective:To investigate the risk factors and their predictive efficacy for early postoperative complications in elderly patients with hip fracture.Methods:A retrospective cohort study was conducted on the clinical data of 203 elderly patients with hip fracture admitted to the 908th Hospital of the Joint Logistics Support Force of the PLA and the First Affiliated Hospital of Nanchang University from January 2022 to December 2023, including 54 males and 149 females, aged 65-100 years [(80.5±7.7)years]. There were 96 patients with femoral neck fracture and 107 patients with intertrochanteric fracture. According to the AO/OTA classification, the fracture was classified as type 31A in 107 patients and type 31B in 96. Among them, 81 patients were treated with proximal femoral nail antirotation (PFNA), 65 with semi-hip arthroplasty, 52 with total hip arthroplasty (THA), and 5 with closed reduction and cannulated nail internal fixation. The patients were divided into complication group ( n=65) and non-complication group ( n=138) according to whether complications (mainly including delirium, lung infection, stress ulcer, and deep vein thrombosis of the lower limbs) occurred within 15 days after surgery. The gender, age, age stage, educational level, cause of injury, associated underlying diseases before surgery, AO/OTA classification, American Society of Anesthesiologists (ASA) classification, 5-factor modified frailty index (mFI-5) score, prognostic nutritional index (PNI), anesthesia method, operation method, operation time, intraoperative blood loss, length of hospital stay, etc., were recorded in the two groups. Univariate analysis and multivariate binary logistic regression analysis were used to evaluate the correlation between the above indexes and the occurrence of early postoperative complications in elderly patients with hip fracture and to determine their independent risk factors. The receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive efficacy of each risk factor for the occurrence of early postoperative complications in elderly patients with hip fracture. Results:Univariate analysis showed a certain correlation between age, age stage, associated underlying diseases before surgery, AO/OTA classification, ASA classification, mFI-5 score, PNI, operation method, and length of hospital stay and the occurrence of early postoperative complications in elderly patients with hip fracture ( P<0.05), while gender, educational level, cause of injury, anesthesia method, operation time, and intraoperative blood loss were not correlated with the occurrence of early postoperative complications in elderly patients with hip fracture ( P>0.05). The results of multivariate binary logistic regression analysis showed that the associated underlying diseases before surgery ( OR=5.46, 95% CI 1.33, 22.39, P<0.05), mFI-5 score ( OR=15.90, 95% CI 5.36, 47.15, P<0.01), and PNI ( OR=0.70, 95% CI 0.60, 0.81, P<0.01) were significantly correlated with the occurrence of early postoperative complications in elderly patients with hip fracture. The results of ROC curve analysis showed that mFI-5 score (AUC=0.85, 95% CI 0.80, 0.91) and PNI (AUC=0.87, 95% CI 0.82, 0.93) had moderate predictive efficacy, while the early warning efficacy of associated underlying diseases was low (AUC=0.54, 95% CI 0.45, 0.62). The combination of the above risk factors was more effective in predicting early postoperative complications in elderly patients with hip fracture (AUC=0.95, 95% CI 0.92, 0.98). Conclusions:The mFI-5 score, PNI, and associated underlying diseases before surgery are independent risk factors for early postoperative complications in elderly patients with hip fracture. The mFI-5 score and PNI have a higher predictive efficacy than associated diseases before surgery on the occurrence of early postoperative complications in elderly patients with hip fracture, while the combination of the above risk factors provides a significantly better predictive performance.

Objective:To evaluate the differential expression of RNA in blood monocytes in patients with Juvenile idiopathic arthritis (JIA) treated with TNF antagonists (TNFi), and to explore the effect and mechanism of gene expression on the efficacy of JIA.Methods:A total of 29 children with JIA treated with methotrexate (MTX) and TNFi in Guangzhou Women and Children′s Medical Center of Guangzhou Medical University from April 2021 to November 2023 were enrolled. After 6 months, the children were divided into two groups according to the treatment effect, 13 cases in the ineffective group and 16 cases in the effective group, the peripheral blood of the children was collected, the blood mononuclear cells were isolated for transcriptome sequencing, the differentially expressed genes between the groups were analyzed, the signaling pathways and metabolic pathways related to the efficacy of TNFi were analyzed by GO and KEGG enrichment, and the mechanism related to the efficacy of TNFi was explored. This study was approved by Medical Ethics Committee of the Guangzhou Women and Children′s Medical Center of Guangzhou Medical University (Ethics No.: 2023-330B00).Results:There was a statistically significant difference in the gender and age distribution between the two groups of children ( P<0.05), while no statistically significant differences were observed in disease duration, rheumatoid antibody levels, or JIA subtypes ( P> 0.05). After sequencing data quality control and comparison of reference genomes, a total of 18 523 protein-coding genes were identified in all children′s samples. A total of 705 differentially expressed genes (DEGs) were identified between the effective group and the invalid group through differential analysis, of which 579 were up-regulated in the effective group and 126 in the inactive group. GO function and KEGG pathway enrichment analysis showed that DEG was significantly enriched in 55 GO entries and 32 KEGG metabolic pathways, which were mainly related to IL-1β; production and regulation, cytokine production and regulation, cytokine-cytokine receptor interaction, immune response regulation, and Toll-like receptor signaling pathway. Conclusion:DEG between the effective and ineffective groups of TNFi treatment may be involved in the biological processes such as cytokine production and regulation, cytokine-receptor interaction, and immune response regulation, which will be helpful to predict the efficacy and prognosis of TNFi treatment for JIA.
