Tumor-associated macrophages(TAM)are a current focus in the study of the tumor microenvironment.To achieve their functionally distinct roles,macrophages undergo phenotypic polarization resulting in two major subgroups:M1 macrophages with pro-inflammatory and anti-tumor effects,and M2 macrophages with anti-inflammatory and pro-tumor effects.Of these,M2 polarization,as the main manifestation of TAMs,has been associated with a poor prognosis in various cancers and has been shown to support malignancies.Gastric carcinoma has a low early-diagnosis rate,late disease stage,and poor prognosis,with biological behavioral characteristics of easy recurrence and metastasis.Drug resistance and toxic side effects currently limit the application and effectiveness of treatments,and there is thus an urgent need to explore new therapeutic drugs and targets.This review summarizes recent progress in studies of TAM in relation to the occurrence,development,and drug resistance of gastric carcinoma,providing new ideas for clinical treatment and prognosis prediction in patients with gastric carcinoma.

Ergonomic Principle for the Prevention of Work-Related Musculoskeletal Disorders Part 1: General Principles (T/WSJD 14.1-2020) is the first guideline standard for the prevention of work-related musculoskeletal disorders provided to employers and occupational health technical service institutions in China, which covers ergonomic risk factors and their hazard definition, ergonomic prevention principles, risk assessment process, risk control process and risk evaluation principles. The standard specifically clarify the specific types of adverse ergonomic risk factors and control strategies and the standard process of systematic ergonomic risk assessment, providing implementation paths and practical guidance for eliminating/reducing adverse ergonomic risks and enhance workplace environments to prevent work-related musculoskeletal disorders. This paper interprets and analyzes the background of standard establishment, formulation process, fundamental basis, and main content, etc., to provide scientific and accurate technical support for enterprise managers, labours and technical personnel of occupational health institutions to optimize the use of this standard.

Perioperative rehabilitation aims to alleviate symptoms,restore function,and improve quality of life.These goals largely involve subjective patient experiences,which are not fully captured by traditional outcome measures.In recent years,patient-reported outcomes(PROs)have emerged as essential tools to quantify patients'perceptions of health and have been widely used in drug and device clinical trials.This review summarizes the current applications of PROs in general surgery,including symptom description,comparison of surgical methods,complication warning,and patient management.Practical cases and evidence from domestic and international studies are discussed.With the integration of electronic PROs(ePROs),artificial intelligence,and natural language processing,future efforts should focus on developing localized,specialty-specific tools and establishing stronger correlations between PROs and clinical outcomes to support the transition from disease-centered to patient-centered surgical care.

Background and Aims:Surgical treatment is a cornerstone of breast cancer management;however,the physical trauma and psychological burden associated with surgery may adversely affect patients'quality of life(QoL).Based on data from a prospective cohort,this study was conducted to evaluate changes in postoperative QoL among breast cancer patients and to identify mediating factors influencing QoL,thereby providing evidence for perioperative rehabilitation strategies.Methods:Female breast cancer patients who underwent local surgical treatment at Suining Central Hospital between June 2024 and January 2025 were enrolled.The Constant-Murley Shoulder Score,EORTC QLQ-C30,and QLQ-BR23 questionnaires were used pre-and postoperatively to assess shoulder joint function,and QoL.Paired t-tests were used to analyze changes in scores before and after surgery.A mediation model was applied to explore the indirect pathways through which surgery impacts QoL.Additionally,subgroup analyses were conducted to compare QoL changes across different surgical modalities.Results:A total of 148 patients were included,with median age of 54(46-60)years old Postoperative psychological health significantly improved,while shoulder function and overall QoL scores markedly declined(all P<0.001).According to QLQ-C30,functional domains such as physical and role functioning worsened,while symptom burden increased.The QLQ-BR23 revealed significantly higher scores for breast and upper limb symptoms postoperatively(both P<0.001).Subgroup analyses showed that patients undergoing axillary lymph node dissection experienced greater declines in shoulder function and QoL compared to those receiving sentinel lymph node biopsy(both P<0.05).QoL deterioration was comparable between mastectomy and breast-conserving surgery,although the former was associated with more prominent pain and breast symptoms.Mediation analysis indicated that shoulder function,breast symptoms,and physical functioning served as mediators in the impact of surgery on QoL,while better psychological health exerted a protective effect.Conclusion:Surgical treatment significantly affects postoperative QoL in breast cancer patients,with local functional impairment and symptom exacerbation serving as key mediators.Different surgical approaches have varying impacts on QoL.Enhancing postoperative shoulder rehabilitation,symptom management,and psychological support may improve patients'QoL.

Objective To explore the relationship between thyroid function and hyperactivity behavior(HB)in children with attention deficit hyperactivity disorder(ADHD),and further understand the potential factors contributing to increased risk of ADHD,and provide references for the treatment of ADHD in children.Methods A total of 134 pediatric ADHD patients who were treated and followed up at Huzhou Central Hospital from February 2018 to August 2023 were selected as the research subjects.According to the hyperactivity index(HI),they were divided into non HB group(n=71)and HB group(n=63).General information and routine laboratory parameters were compared between two groups.HB-related factors were evaluated by using binary Logistic regression analysis.Finally,Pearson linear correlation analysis and receiver operating characteristic curve were used to study the relationship between HB and thyroid stimulating hormone(TSH)and the potential diagnostic value of TSH levels in distinguishing ADHD children with HB.Results The differences in lactic acid and TSH levels between two groups of cases were statistically significant,with HB group significantly higher compared to non HB group(P＜0.05).Among them,TSH level was independently associated with HB and positively correlated with HI score(r=0.668,P＜0.00 1).Additionally,TSH level had a certain value in distinguishing ADHD children with HB,with a cut-off point of 2.57 μIU/ml(sensitivity was 65.1％,specificity was 74.7％).Conclusion This study revealed a positive correlation between serum TSH level and HB in children with ADHD,and it can be used to differentiate ADHD children with HB.
