BackgroundIn recent years， the incidence of depression among adolescents has been increasing steadily， posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time， the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria， they have significantly affected their quality of life， and their persistence over time may further develop into depression. Therefore， in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However， up to now， no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region， in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method， 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale （SDS） were used for on-site investigation. ResultsA total of 6 058 （96.45%） children and adolescents completed the valid questionnaire survey， and 2 728 cases （45.03%） were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders， ages， whether they were only children， different family types， family monthly income， parents' educational levels， and whether the mother was employed （χ²=33.769， 40.618， 48.593， 29.972， 142.648， 195.999， 168.190， 5.445， P<0.05 or 0.01）.The results of the Logistic regression analysis showed that for children and adolescents， being female， aged between 12 and 16， over 16 years old， not being an only child， living in a reconstituted family， having a monthly family income of less than 5 000 yuan， and having parents with an education level of primary school or below were predictors of depressive symptoms （OR=1.241， 1.427， 1.273， 1.177， 1.549， 1.278， 1.462， 1.417， 1.514， 1.929， 1.660， 1.528， P<0.05 or 0.01）. ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender， ages between 12 and 16， ages over 16 years old， non-only children， families with a restructured structure， monthly family income of less than 5 000 yuan， and parents with an education level of primary school or below. ［Funded by Science and Technology Planning Project of the Inner Mongolia Autonomous Region （number， 2022YFSH0119）］

Objective To analyze the related factors of retinopathy in elderly patients with type 2 diabetes mellitus (T2DM) and explore the discriminant efficiency. Methods A retrospective analysis was conducted on 314 elderly patients with T2DM who were treated in Beijing Aerospace General Hospital between April 2022 and April 2025. The related factors of retinopathy in elderly patients with T2DM were explored by logistic regression analysis. ROC curve was drawn to analyze the discriminant efficiency of related factors. Results Compared with the patients in the non-concurrent group, the patients in the concurrent group had a longer course of diabetes mellitus, a higher level of glycosylated hemoglobin (HbA1c), and higher proportions of diabetic peripheral neuropathy, hypertension history, high myopia history and smoking history (P<0.05). After logistic regression analysis, the course of diabetes mellitus, HbA1c, diabetic peripheral neuropathy, history of hypertension and history of high myopia were found to be related factors of retinopathy in elderly patients with T2DM (P<0.05). Based on the above related factors, a model was established for ROC curve analysis, and it was found that the area under the curve was 0.935, with sensitivity, specificity, and 95%CI being 0.867, 0.916, and 0.890-0.979, respectively. Conclusion Course of diabetes mellitus, HbA1c, diabetic peripheral neuropathy, history of hypertension, and history of high myopia are related factors of retinopathy in elderly patients with T2DM. These related factors demonstrate good discriminant efficiency on retinopathy in elderly patients with T2DM.

Uveal melanoma(UM)is the most common primary intraocular malignancy in adults, characterized by high invasiveness and unique metastatic biological features. Although local treatments(such as proton beam therapy and brachytherapy)can effectively control the primary lesion, approximately 50% of patients eventually develop distant metastasis, with the liver being the primary target organ(occurring in 90% of cases). This highlights a paradigm shift in treatment focus from mere local control to systemic prevention and management. For metastatic UM(mUM), current treatment strategies encompass biomarker-guided molecular targeted therapy, immunotherapy(including Tebentafusp, vaccines, and oncolytic virus therapy), and liver-directed therapy. Focusing on the synergy between local and systemic prevention and control, this article systematically elaborates on the precision local treatment for primary UM, the decision-making pathway for systemic treatment of metastatic UM based on molecular subtyping, the integration of local and systemic therapies for liver metastases, and the translational value of nanomedicine in addressing therapeutic bottlenecks. It provides insights for optimizing clinical management of mUM and developing novel therapeutic strategies.

[摘 要] 目的：探究外周血1型辅助性T细胞（Th1）/Th2/Th17细胞相关细胞因子IL-2、IL-4、IL-6、IL-10、IFN-γ、TNF-α、IL-17A对Ⅲ~Ⅳ期肺鳞状细胞癌（LSCC）患者一线免疫治疗联合化疗疗效和预后的预测价值及其动态变化的意义。方法：回顾性分析2020年1月至2023年12月在内蒙古医科大学附属医院接受一线免疫治疗联合化疗的58例Ⅲ~Ⅳ期LSCC患者的临床资料，采集基线及治疗2、4、6周期后和疾病进展时的外周血，用流式细胞术检测Th1/Th2/Th17细胞分泌的细胞因子水平，用受试者工作特性曲线（ROC）确定各细胞因子基线的最佳截断值，据此将患者分为高、低表达组；根据RECIST 1.1标准，将患者分为客观缓解（ORR）[完全缓解（CR） + 部分缓解（PR）]组、非ORR[（疾病稳定（SD） + 疾病进展（PD）]组、疾病控制（DCR）（CR + PR + SD）组和非DCR（即PD）组；根据PD-L1表达评分将患者分为PD-L1 ≥ 1%组和PD-L1 < 1%或未知组。比较组间疗效的差异；分析临床病理特征与疗效的相关性；用广义估计方程（GEE）评估细胞因子动态变化与疗效的关系；用Kaplan-Meier法绘制生存曲线，Log-Rank检验比较组间差异，COX比例风险回归模型进行单因素及多因素预后分析。结果：IL-2和IFN-γ高表达组患者的客观缓解率（ORR）显著高于低表达组患者（P < 0.001）。IL-2、IFN-γ高表达组和IL-10、TNF-α低表达组患者的疾病控制率（DCR）均显著高于对应低/高表达组（P < 0.001）。PD-L1 ≥ 1%组DCR显著高于PD-L1 < 1%或未知组（P < 0.001）。动态分析显示，在4周期及6周期时，有效组患者血清中IL-6表达水平显著低于无效组（P < 0.05），控制组IL-6表达水平显著低于未控制组（P < 0.001）；治疗前及6周期时有效组IFN-γ表达水平显著高于无效组（P < 0.05），治疗前控制组IFN-γ表达水平显著高于未控制组（P < 0.05）。生存分析显示，IL-2低表达组、IL-10高表达组、TNF-α高表达组和IFN-γ低表达组患者的中位PFS显著缩短（均P < 0.05）。COX多因素分析证实，治疗前IL-2 < 2.45 pg/mL和IL-10 ≥ 3.52 pg/mL 是PFS的独立危险因素。结论：外周血Th1/Th2/Th17细胞相关细胞因子的基线水平及动态变化对Ⅲ~Ⅳ期LSCC患者一线免疫治疗联合化疗的疗效和预后具有预测价值。

Hepatocellular carcinoma (HCC) develops within a profoundly immunosuppressive tumor immune microenvironment (TIME), which limits the efficacy of immunotherapy. Polarization of tumor-associated macrophages (TAMs) toward a pro-tumorigenic M2 phenotype is a major driver of immune escape. Ferroptosis, an iron-dependent regulated cell death program, intersects with hepatic iron metabolism and immune regulation and thus offers promising points of therapeutic intervention. This review systematically elucidates the mechanistic role of TAM ferroptosis in HCC immune evasion and highlights a “bidirectional regulation” intervention strategy grounded in the Traditional Chinese medicine (TCM) principle of “fortifying healthy qi and eliminating pathogens” (Fuzheng Quxie). This strategy employs “eliminating pathogens” (Quxie) approaches to exploit the metabolic vulnerability of M2-like TAMs and precisely induce their ferroptosis. Moreover, it utilizes “fortifying healthy qi” (Fuzheng) approaches to protect M1-like TAMs and CD8⁺ T cells from oxidative damage. This parallel “induction-protection” paradigm demonstrates the unique advantages of TCM in systemically remodeling TIME through multitarget synergistic actions. Accordingly, precision regulation of TAM ferroptosis based on the Fuzheng Quxie theory represents a promising integrative Chinese-Western medicine strategy for overcoming current bottlenecks in HCC immunotherapy, although its clinical translational potential warrants further validation.

The red doctor spirit is the advanced culture of the Communist Party of China formed under a specific historical and cultural background. It can be summarized as “political firmness， excellent technology， working hard， and healing the wounded and rescuing the dying.” This content has many hidden similarities and integrations with the goal of cultivating humanistic literacy for medical students in military medical universities. This paper aimed to identify the important connection points between the red doctor spirit and the contents and goals of medical humanities teaching， as well as integrate the red doctor spirit into medical humanities teaching by various dimensions， including systematic reconstruction of textbook content， immersive innovation in teaching form， three-dimensional support in resource construction， and innovative implementation of narrative medicine teaching. It also further explored the extension of the red doctor spirit in military medical humanistic literacy， namely， revolutionary humanism and revolutionary heroism， thereby enhancing the effectiveness of medical humanistic teaching.

Objective To investigate the correlation of solute carrier protein 17 family member 1 (SLC17A1) gene single nucleotide polymorphisms (SNPs) and susceptibility to hyperuricemia (HUA) in automotive manufacturing workers. Methods A total of 192 Han male workers diagnosed with HUA were selected as the case group, 192 Han male workers without HUA from the same enterprises were selected as the control group. These workers were determined by the matching factor of age, total length of service, and body mass index by the 1∶1 case-control study method. Peripheral venous blood from the workers was collected for DNA extraction. Two SNPs of SLC17A1 were genotyped by MassArray system. Results The gene frequency distributions of SLC17A1 rs2096386 and rs1183201 of workers in the control group were in consistent with the Hardy-Weinberg equilibrium test (both P>0.05). The allele frequency distribution of rs2096386, and the genotype and allele frequency distribution of rs1183201 were significantly different between workers in the two groups (all P<0.05). There was no significant difference in genotype frequency distribution of rs2096386 between workers in the two groups (P>0.05). The results of conditional logistic regression analysis showed that workers with G allele at rs2096386 increased the risk of HUA [odds ratio (OR)=1.43, 95% confidence interval (CI)=1.01-2.04], workers with T allele at rs1183201 increased the risk of HUA (OR=2.03, 95%CI =1.29-3.19), after adjusting for confounding factors such as serum creatinine, blood urea nitrogen, alanin aminotransferase and aspartate aminotransferase. While workers with TA and TA+AA genotypes at rs1183201 had a lower risk of HUA than those with TT genotype (OR=0.51, 95%CI =0.30-0.85; OR=0.50, 95%CI =0.30-0.83), workers with TA genotype at rs1183201 had a lower risk of HUA than those with TT+AA genotype (OR=0.53, 95%CI =0.32-0.88). Conclusion The polymorphisms at rs2096386 and rs1183201 of SLC17A1 gene may be correlated with HUA susceptibility among automobile manufacturing workers in Guangzhou City.

Objective To investigate the correlation between cytokines and the side effects of estrogen deprivation associated with adjuvant endocrine therapy in female patients with early luminal breast cancer. Methods A retrospective analysis was performed on the data of 70 patients with early-stage breast cancer who underwent both the Endocrine Symptom Scale (FACT-ES) assessment and cytokine testing at the Breast Clinic of the Department of Medical Oncology, Cancer Hospital, Chinese Academy of Medical Sciences, between April 2023 and June 2023. Results Binary logistic regression analysis revealed that breast cancer patients experiencing hot flashes had significantly higher serum levels of IL-5 compared with those without hot flashes (3.17 pg/ml vs. 2.33 pg/ml, OR: 1.307-7.66, P=0.011), and the patients experiencing irritability had significantly lower serum levels of IL-10 (0.83 pg/ml vs. 1.37 pg/ml) and INF-γ (19.91 pg/ml vs. 35.93 pg/ml) compared with those without irritability（OR: 0.855-0.983, P=0.015）. Conclusion The elevated IL-5 may be associated with the occurrence of hot flashes, while lower levels of IL-10 and INF-γ may be linked to irritability in patients with early-stage Luminal breast cancer treated with adjuvant endocrine therapy.

Objective: To investigate the mental health status and related factors among primary and secondary school students in western Yunnan Province, so ao to provide scientific evidences for advancing mental health education. Methods: In June 2024, a stratified cluster sampling method was employed to select 4 584 students from 18 schools across Diqing Tibetan Autonomous Prefecture, Lincang City and Baoshan City three regions in western Yunnan Province. The Mental Health Test (MHT) was used for assessment. Latent class analysis (LCA) and Logistic regression were applied for data classification and related factor analysis respectively. Results: The overall positive detection rate of MHT was 11.81%, with a mean total score of 40.50±19.25. The predominant issues were learning anxiety (58.4%), hypersensitivity tendency (31.1%), and self blame tendency (23.1%). LCA categorized students into four groups:severe psychological problems group (74.4% detection rate), learning anxiety hypersensitivity group ( 16.4 %), learning anxiety physical symptoms group (9.2%), and healthy group (0). Logistic regression revealed that compared with the healthy group, the severe problems group showed higher risks among females ( OR =3.01), junior/senior high school students ( OR =1.88/4.02), and those with authoritarian parenting ( OR =3.54); the anxiety hypersensitivity group had higher risks for females ( OR =1.87), senior high students ( OR =1.54), boarders ( OR =1.31), and authoritarian parenting recipients ( OR = 1.85 ); the anxiety physical symptoms group demonstrated increased risks among females ( OR =2.22), senior high students ( OR =2.58), and authoritarian parenting recipients ( OR =2.74), while lower risks were observed for students with parent/grandparent guardians ( OR =0.38) and non only children ( OR =0.58) (all P <0.05). Conclusions Mental health problems are prominent among students in western Yunnan, with gender, grade level, boarding status, guardian type, and parenting style being key determinants. Recommendations include strengthening mental health education, prioritizing left behind children s psychological well being and promoting healthy development.
