ObjectiveTo observe the changes in the levels of different subtypes of epidermal growth factor receptor （ErbB）， namely ErbB1， ErbB2， ErbB3， and ErbB4， in the spinal dorsal horn of inflammatory pain model rats， and to explore their mechanism of mediating hyperalgesia as well as the intervention mechanism of electroacupuncture at "Zusanli （ST 36）" and "Kunlun （BL 60）". MethodsThe study was divided into five parts. In experiment 1， 14 Sprague Dawley （SD） rats were randomly divided into control and inflammatory pain group （7 rats each group） to observe the pain behavior and the protein expression of different ErbB receptor subtypes in the spinal dorsal horn. In experiment 2， 30 rats were randomly divided into control group 1， inflammatory pain group 1， and low-， medium-， and high-concentration TX1-85-1 groups， with 6 rats in each group， to observe the effect of inhibiting spinal ErbB3 on inflammatory pain. In experiment 3， 12 rats were randomly divided into control virus group and ErbB3 knockdown virus group， with 6 rats in each group， to observe the effect of knocking down ErbB3 in the spinal dorsal horn on inflammatory pain. In experiment 4， 44 rats were randomly divided into control group 2， inflammatory pain group 2， electroacupuncture group， and sham electroacupuncture group， with 11 rats in each group， to observe the effect of electroacupuncture. In experiment 5， 40 rats were randomly divided into control group 3， inflammatory pain group 3， electroacupuncture group 1， and electroacupuncture + NRG1 group， with 10 rats in each group， to observe the effect of activating ErbB3 on electroacupuncture. A rat model of inflammatory pain was established by subcutaneous injection of 100 μl of complete Freund's adjuvant into the sole of the unilateral hind foot of SD rats. Rats in the low-， medium-， and high-concentration TX1-85-1 groups were intrathecally injected with ErbB3 inhibitor TX1-85-1 on day 5 to day 7 after modeling. Rats in the ErbB3 knockdown virus group were injected with ErbB3 knockdown virus packaged with adenovirus vector-based short hairpin RNA （shRNA） into the spinal dorsal horn in situ 3 weeks before modeling. Rats in each electroacupuncture group received electroacupuncture at bilateral "Zusanli （ST 36）" and "Kunlun （BL 60）" from day 1 to day 7 after modeling， with dense-sparse waves at a frequency of 2 Hz/100 Hz and a current of 0.5-1.5 mA for 30 minutes once a day. Rats in the electroacupuncture + NRG1 group were intrathecally injected with ErbB3 ligand recombinant human neuregulin-1 （NRG1） after electroacupuncture intervention from day 5 to day 7 after modeling. The mechanical withdrawal threshold and thermal withdrawal latency of rats were measured on day 1， 3， 5， and 7 after modeling to evaluate behavior， and Western Blot was used to detect the protein and phosphorylation levels of each ErbB subtype in the spinal dorsal horn. ResultsCompared with the control group， rats in the inflammatory pain group showed decreased mechanical withdrawal threshold and thermal withdrawal latency of rats， and increased expression of phosphorylated ErbB3 （p-ErbB3） protein in the spinal dorsal horn on days 1， 3， 5， and 7 after modeling （P＜0.01）. On day 5 and day 7 after modeling， compared with the inflammatory pain group 1， the mecha-nical withdrawal threshold and thermal withdrawal latency of rats in the medium- and high-concentration TX1-85-1 groups increased， and the expression of p-ErbB3 protein decreased （P＜0.05）. On day 1， 3， 5， and 7 after modeling， compared with the control virus group， the mechanical withdrawal threshold and thermal withdrawal latency of rats in the ErbB3 knockdown virus group increased （P＜0.05）. On day 5 and day 7 after modeling， compared with the inflammatory pain group 2 and the sham electroacupuncture group， the mechanical withdrawal threshold and thermal withdrawal latency of rats in the electroacupuncture group increased， and the expression of p-ErbB3 protein decreased （P＜0.05）. On day 5 and day 7 after modeling， compared with the electroacupuncture + NRG1 group， the mechanical withdrawal threshold and thermal withdrawal latency of rats in the electroacupuncture group 1 increased （P＜0.05）. ConclusionThe p-ErbB3 in the spinal dorsal horn involved in hyperalgesia in rats with inflammatory pain， and electroacupuncture at "Zusanli （ST 36）" and "Kunlun （BL 60）" can alleviate inflammatory pain by inhibiting the expression of p-ErbB3 protein in the spinal dorsal horn of rats.

Objective: To investigate the factors influencing the co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia, so as to provide a data foundation and theoretical basis for developing targeted intervention measures. Methods: In September and October 2024, a stratified cluster random sampling method was employed to select 139 102 students from 539 schools across 12 leagues/cities and 103 banners/counties in Inner Mongolia Autonomous Region. Participants who were diagnosed with allergic rhinitis by a doctor at least once within one year and had a body mass index ≥ 28 kg/m 2 were considered to have comorbid conditions. Results: The coprevalence rate of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia was 6.4% (8 931 cases). Lasso-Logistic regression revealed that nonboarding status, higher maternal education, consuming high protein foods ≥1 time daily, occasionally or never eating breakfast, engaging in moderate to vigorous physical activity for ≥60 minutes on fewer than half of holidays, and having been exposed to second hand smoke in person within the past seven days were associated with higher odds ratios for co-prevalence of allergic rhinitis and obesity( OR = 1.23 , 1.22-1.63, 1.20, 1.19, 1.38, 1.35); being female, higher grade level, residence in flag/county/district areas, non only child status, never having consumed a full glass of alcohol, non hypertensive status, and households without pets were associated with lower co-prevalence risks ( OR =0.65, 0.67-0.77, 0.81, 0.87, 0.73, 0.41, 0.68) (all P <0.05). The ROC curve indicated an area under the curve of 0.64 for the predictive model, demonstrating satisfactory discriminatory ability. The calibration curve showed consistency between predicted and actual occurrence probabilities. Conclusions The co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia is closely associated with demographic characteristics, dietary behaviours, and lifestyle habits. Future prevention and control strategies should prioritize these factors to implement targeted interventions.

Cancer remains a leading cause of global mortality, necessitating the development of advanced therapeutic strategies with enhanced efficacy and reduced systemic toxicity. Among promising bioactive agents, lactoferrin (LF)—a multifunctional iron-binding glycoprotein abundantly found in mammalian milk and exocrine secretions—has garnered significant interest for its potent and multifaceted anti-cancer properties. This review provides a comprehensive analysis of the current understanding of LF’s role in oncology, encompassing its structural biology, diverse mechanisms of action, and groundbreaking advancements in its application through nano-engineering. LF exerts anti-tumor effects through multiple pathways, including extracellular action, intracellular action, and immune regulation. It demonstrates a remarkable affinity for cancer cell membranes, binding to overexpressed anionic components such as glycosaminoglycans and sialic acids, as well as to specific receptors including the low-density lipoprotein receptor-related protein-1 (LRP-1). This selective binding facilitates targeted uptake. Upon internalization, LF orchestrates a direct assault by inducing cell-cycle arrest in phases such as G0/G1 or S phase through the modulation of key regulators including cyclins, CDKs, and p53. Furthermore, it promotes programmed cell death via apoptotic pathways, involving caspase activation and downregulation of anti-apoptotic proteins such as survivin. A more recently elucidated mechanism is the induction of ferroptosis, an iron-dependent form of cell death characterized by overwhelming lipid peroxidation. Beyond direct cytotoxicity, LF acts as a potent immunomodulator. It enhances natural killer (NK) cell activity, modulates T-lymphocyte populations, and crucially reprograms tumor-associated macrophages (TAMs) from a pro-tumor M2 state to an anti-tumor M1 state, thereby reversing the immunosuppressive tumor microenvironment (TME). The translation of LF’s potential has been significantly accelerated by nanotechnology. The inherent biocompatibility and natural tumor-targeting capabilities of LF make it an ideal platform for sophisticated drug-delivery systems. This review details various fabrication strategies for LF-based nanoparticles (NPs), including self-assembly, sol-in-oil emulsion, and electrostatic nanocomplexes, among others. Research demonstrates that nano-formulations not only protect LF from degradation but also enhance its bioactivity and anti-cancer potency. More importantly, LF NPs serve as versatile carriers for a wide array of therapeutic agents, including conventional chemotherapeutics, natural compounds, and imaging agents. These engineered systems enable synergistic therapy and facilitate site-specific delivery. Notably, the ability of LF to bind to receptors on the blood-brain barrier (BBB) has been leveraged to develop nano-systems for glioblastoma treatment. Other innovative designs utilize LF to modulate the TME—for instance, by alleviating tumor hypoxia to sensitize cells to radiotherapy and chemotherapy. Despite compelling pre-clinical evidence, the clinical translation of LF and its nano-formulations remains nascent. While early-phase trials have established a favorable safety profile for recombinant human LF, larger Phase III studies have yielded mixed results, underscoring the complexity of its action in humans. Key challenges include enhancing drug targeting, optimizing loading efficiency, ensuring batch-to-batch reproducibility, and achieving deep tumor penetration. Future research must focus on the rational design of next-generation LF-NPs. This entails developing standardized manufacturing protocols, engineering “smart” stimuli-responsive systems for targeted drug release in the TME, and constructing multi-targeting platforms. A concerted interdisciplinary effort is paramount to bridge the gap between bench and bedside. In conclusion, LF, particularly in its nano-engineered forms, represents a highly promising and versatile agent in the oncological arsenal, holding immense potential for precise and effective cancer therapy.

Objective To construct and evaluate a prognostic model for clear cell renal cell carcinoma(ccRCC)based on preoperative lipid ratios, cM0(i+)staging, and other clinical characteristics, so as to provide a precise tool for clinical prognosis assessment. Methods A retrospective analysis was conducted on the clinical data of 215 ccRCC patients treated in our hospital during May 2014 and May 2023. Lipid ratios were calculated using preoperative lipid data, and patients were divided into cM0(i+)stage or cM0 stage according to postoperative circulating tumor cells(CTCs)test results. The optimal lipid ratio and cutoff value were selected using receiver operating characteristic(ROC)curves and the X-tile method. Patients were subdivided into three groups based on the level of the low-density lipoprotein cholesterol to non-low-density lipoprotein cholesterol ratio(LNLR)and cM0(i+)staging:Group A [LNLR＞1.68 and diagnosed with cM0(i+)], Group B [LNLR＞1.68 or diagnosed with cM0(i+)], and Group C(LNLR ≤1.68 and diagnosed with cM0). Kaplan-Meier survival analysis was used to plot survival curves for patients in different groups. The log-rank test was employed to compare differences in recurrence-free survival(RFS)among the subgroups. Multivariate Cox regression analysis was conducted to identify the independent risk factors influencing RFS, and a nomogram prediction model was constructed based on these results. The predictive performance of the model was validated using ROC curves, calibration curves, and decision curves. Results ROC curves were plotted for lipid markers, and LNLR was identified as the most predictive for RFS. Its optimal cutoff point was 1. 68. Patients in Group A experienced a significantly shorter postoperative RFS. Multivariate Cox regression analysis identified preoperative LNLR, cM0(i+)staging, pathological grade, and stage as independent risk factors for RFS. A nomogram model was constructed based on these risk factors. The area under the ROC curve(AUC)for 1-, 3-, and 5-year RFS was 0.896(95% CI:0.8121-0.9627), 0.890(95%CI:0.7879-0.9641), and 0.870(95%CI:0.7697-0.9526), indicating good discriminatory ability and predictive performance. Calibration plots demonstrated good agreement between predicted and actual outcomes. Clinical decision curve analysis showed high clinical net benefit. Conclusion Preoperative LNLR level is an independent risk factor for RFS in ccRCC patients. The prognostic prediction model based on LNLR, cM0(i+)staging, patient pathological grade, and staging demonstrates good predictive performance for RFS and holds potential clinical application value.

By integrating cutting-edge technologies including single-cell multi-omics, spatial transcriptomics and novel animal models, significant breakthroughs have been achieved in the evolutionary dynamics of drug-resistant infections, molecular mechanisms of immune regulation, programmed cell death, optimization of donor lung protection strategies and early warning of chronic lung allograft dysfunction. This article systematically reviews the representative advances in basic lung transplantation research worldwide in 2025, and deeply analyzes the implications of mechanistic breakthroughs for optimizing diagnosis and treatment strategies, aiming to anchor the direction for innovative breakthroughs and clinical translation in basic lung transplantation research.

With the accelerating aging of the population, the proportion of elderly patients with lung cancer continues to rise, presenting multiple challenges to perioperative management. This paper systematically reviews the clinical characteristics of elderly lung cancer patients. Based on the comprehensive geriatric assessment, it proposes incorporating seven major geriatric syndromes—frailty, delirium, sarcopenia, cognitive impairment, malnutrition, dysphagia, and mood disorders—into the core evaluation system. By integrating multimorbidity management with complication prevention and control, an integrated "geriatric syndrome-multimorbidity-complication" perioperative management model is constructed. Furthermore, this paper outlines stratified intervention strategies for geriatric syndromes, a "five-step" workflow for comorbidity management, and a comprehensive intervention pathway for complications across the preoperative, intraoperative, and postoperative phases. Multidisciplinary team (MDT) collaboration serves as the core mechanism to achieve individualized comprehensive treatment. This paper aims to provide a novel perioperative comprehensive treatment model for elderly lung cancer patients, which is centered on geriatrics, supported by multidisciplinary collaboration, and guided by precision medicine.

BackgroundPatients with colorectal cancer are frequently comorbid with depression， which severely affects the quality of life and treatment compliance， while compromising the efficacy of anticancer treament and prognosis. Current therapeutic strategies still have notable limitations， particularly the lack of systematic and targeted synergistic regimens that integrate oncological management and anti-depressive intervention. It is of great clinical significance to explore a safe and effective new comprehensive intervention protocol and clarify its underlying mechanism of action. ObjectiveTo explore the effectiveness and safety of Shugan Yunpi Decoction in alleviating depressive and anxiety symptoms in colorectal cancer patients with depressive disorder through the PI3K-AKT signaling pathway， in order to provide references for the comprehensive treatment of colorectal cancer and depressive disorder. MethodsThis study was a randomized controlled trial. A total of 106 patients admitted to the Baoding No.1 Hospital of traditional Chinese medicine from November 2023 to July 2025 were enrolled， who met the diagnostic criteria for the Chinese protocol of diagnosis and treatment of colorectal cancer （2023 edition） and the diagnostic criteria for depressive disorder as specified in the Chinese Classification and Diagnostic Criteria of Mental Disease， third edition （CCMD-3）. Patients were divided into the study group and the control group using a random number table， with 53 cases in each group. The control group received conventional chemotherapy combined with traditional Chinese medicine five-element music therapy， while the study group received conventional chemotherapy combined with Shugan Yunpi Decoction therapy. Both groups were treated for 8 weeks. Depressive and anxiety symptoms were assessed using the Hamilton Depression Scale-17 item（HAMD-17） and Hamilton Anxiety Scale （HAMA）， respectively. Western blot protein immunoblotting was used to detect the expression levels of PI3K， AKT， and pAKT. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （qRT-PCR） was used to detect the expression levels of PI3K mRNA and AKT mRNA. Adverse reactions were recorded using a self-designed adverse reaction record form. ResultsRepeated measures analysis of variance showed that the time effects （F=139.336， 234.747）， group effects （F=43.900， 101.266）， and time-group interaction effects （F=13.409， 43.216） for HAMD-17 and HAMA scores in both groups were statistically significant （P<0.01）. After 4 and 8 weeks of treatment， the HAMD-17 and HAMA scores in both groups were lower than those before treatment， with statistically significant differences （P<0.05）. HAMD-17 and HAMA scores in the study group were lower than those in the control group （P<0.05）. The time effects （F=571.356， 309.266， 414.492）， group effects （F=6.901， 26.361， 39.362）， and time-group interaction effects （F=18.592， 19.266， 33.484） for the protein expression levels of PI3K， AKT， and pAKT in both groups were all statistically significant （P<0.01）. After 8 weeks of treatment， the protein expression levels of PI3K and pAKT in the study group were lower than those in the control group， while the AKT protein expression level was higher than that in the control group（P<0.01）. The time effects （F=338.555， 225.059）， group effects （F=5.429， 9.726）， and time-group interaction effects （F=12.953， 21.214） for PI3K mRNA and AKT mRNA expression levels in two groups were all statistically significant （P<0.01）. After 8 weeks of treatment， the expression levels of PI3K mRNA and AKT mRNA in the study group were lower than those in the control group （P<0.05）. The incidence of adverse reactions in the study group was lower than that in the control group （χ²=4.810， P<0.05）. ConclusionShugan Yunpi Decoction may help to ameliorate depressive and anxiety symptoms in colorectal cancer patients with depressive disorder by regulating the PI3K-AKT signaling pathway， decreasing the levels of PI3K， pAKT， PI3K mRNA， and AKT mRNA， with a favorable safety profile. ［Funded by Baoding City Science and Technology Planning Project （number， 2341ZF291）］

Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

ObjectiveTo observe the effect of heat-sensitive moxibustion on quality of life and immune function in non-small cell lung cancer （NSCLC） patients undergoing chemotherapy. MethodsSeventy NSCLC patients with qi deficiency and phlegm stasis syndrome were randomly divided into an intervention group and a control group， with 35 cases in each group. The control group received chemotherapy combined with routine symptomatic treatment， while the intervention group additionally received heat-sensitive moxibustion since the first day of chemotherapy. Acupoints included Dazhui （GV14）， bilateral Feishu （BL13）， Zhongwan （CV12）， Qihai （CV6）， and Guanyuan （CV4）. The site exhibiting the strongest heat-sensitization response was selected for moxibustion. Treatment was administered for 45 minutes per session， three times weekly for three consecutive weeks， totaling nine sessions. Before and after treatment， quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire （EORTC QLQ-C30）， and traditional Chinese medicine （TCM） syndrome scores were evaluated. Peripheral blood levels of natural killer （NK） cells and T-lymphocyte subsets including CD3⁺， CD4⁺， and CD8⁺， and CD4⁺/CD8⁺ ratio were measured. Levels of programmed cell death protein-1 （PD-1）， including PD-1⁺CD4⁺ and PD-1⁺CD8⁺ cells， were also assessed. Liver and renal function were monitored before and after treatment， and adverse events were recorded. ResultsIn the intervention group， 1 participant withdrew and 1 was excluded， while in the control group， 2 participants withdrew. Ultimately， 33 participants in each group were included in the final analysis. The intervention group showed significant improvements in physical， role， emotional， cognitive， and social functioning， as well as global health status after treatment， while scores for fatigue， nausea and vomiting， dyspnea， appetite loss， diarrhea， and TCM syndrome scale were significantly decreased （P＜0.05）. Moreover， the intervention group demonstrated higher scores in physical functioning， role functioning， and global health status， as well as lower scores for fatigue， nausea and vomiting， dyspnea， appetite loss， diarrhea， and the TCM syndrome scale than the control group （P＜0.05）. After treatment， the levels of peripheral NK cells and PD-1⁺CD8⁺ T cells in the intervention group increased significantly； furthermore， the intervention group exhibited higher peripheral NK cell levels and lower PD-1⁺CD8⁺ T cell levels than the control group （P＜0.05）. No significant differences were found in liver or renal function between the two groups （P＞0.05）. In addition， no adverse events such as burns or moxibustion-induced syncope occurred during the study. ConclusionHeat-sensitive moxibustion as an adjunctive therapy may enhance immune function， alleviate clinical symptoms， and improve quality of life， while demonstrating a favorable safety profile in NSCLC patients with qi deficiency and phlegm stasis.
