OBJECTIVE To develop the quality evaluation standard indicator system for hospital cough and wheeze pharmaceutical care clinic （CWPC） pharmacist training within the layered learning practice model （LLPM）， and apply it in clinical practice. METHODS Our teaching team established an LLPM model to train cough and wheeze pharmacists， according to the actual conditions of our college. Using qualitative interview methods， expert questionnaires were compiled with literature research； the expert correspondence methods were employed to conduct two rounds of consultation with 10 domestic respiratory medicine experts， thus constructing an evaluation index system for the teaching quality of cough and wheeze pharmacists. The experts’ positive coefficient， authority coefficient， Kendall’s harmony coefficient， and the degree of concentration of opinions were calculated. The analytic hierarchy process （AHP） was used to determine the weight of each indicator within the index system. From June 2023 to June 2024， the teaching team enrolled 21 pharmacists in the training program. The teaching team assessed and scored the trial group （LLPM） and control group （traditional teaching model） based on the benefit indicators for pharmacists and patients in the evaluation index system， and compared the results. RESULTS This study explored the establishment of a training system for cough and wheeze pharmacists under the LLPM model， and initially established an evaluation index system using the Delphi method. In two rounds of Delphi method questionnaires， the recovery rate was 100%， with an authority coefficient exceeding 0.8， Kendall’s harmony coefficient ranging from 0.235 to 0.459， and all P-values being less than 0.05. Four primary （comprising trainee feedback， learning gains， behavioral improvements， and training performance）， 12 secondary and 33 tertiary indicators were finalized. In the empirical evaluation， the results of the two groups showed a significant benefit to the pharmacists in the trial group. Specifically， the percentage of patients receiving corticosteroids for COPD or wheeze service patients per month （80.5%）， an average increase in the number of cough and wheeze team service outpatient visits per month （compared to the same period of the previous year） of 14.8 visits per month， and the patient satisfaction score （4.9） were all significantly higher than those in the control group （P＜0.05）. CONCLUSIONS The application of the LLPM in competency training for pharmacists specializing in cough and wheeze care yields multiple benefits and holds significant guiding value. The constructed training quality evaluation index system under this model is scientific and reliable.

Exercise-induced metabolic remodeling is a fundamental adaptive process whereby the body reorganizes systemic and cellular metabolism to meet the dynamic energy demands posed by physical activity. Emerging evidence reveals that such remodeling not only enhances energy homeostasis but also profoundly influences immune function through complex molecular interactions involving glucose, lipid, and protein metabolism. This review presents an in-depth synthesis of recent advances, elucidating how exercise modulates immune regulation via metabolic reprogramming, highlighting key molecular mechanisms, immune-metabolic signaling axes, and the authors’ academic perspective on the integrated “exercise-metabolism-immunity” network. In the domain of glucose metabolism, regular exercise improves insulin sensitivity and reduces hyperglycemia, thereby attenuating glucose toxicity-induced immune dysfunction. It suppresses the formation of advanced glycation end-products (AGEs) and interrupts the AGEs-RAGE-inflammation positive feedback loop in innate and adaptive immune cells. Importantly, exercise-induced lactate, traditionally viewed as a metabolic byproduct, is now recognized as an active immunomodulatory molecule. At high concentrations, lactate can suppress immune function through pH-mediated effects and GPR81 receptor activation. At physiological levels, it supports regulatory T cell survival, promotes macrophage M2 polarization, and modulates gene expression via histone lactylation. Additionally, key metabolic regulators such as AMPK and mTOR coordinate immune cell energy balance and phenotype; exercise activates the AMPK-mTOR axis to favor anti-inflammatory immune cell profiles. Simultaneously, hypoxia-inducible factor-1α (HIF-1α) is transiently activated during exercise, driving glycolytic reprogramming in T cells and macrophages, and shaping the immune landscape. In lipid metabolism, exercise alleviates adipose tissue inflammation by reducing fat mass and reshaping the immune microenvironment. It promotes the polarization of adipose tissue macrophages from a pro-inflammatory M1 phenotype to an anti-inflammatory M2 phenotype. Moreover, exercise alters the secretion profile of adipokines—raising adiponectin levels while reducing leptin and resistin—thereby influencing systemic immune balance. At the circulatory level, exercise improves lipid profiles by lowering pro-inflammatory free fatty acids (particularly saturated fatty acids) and triglycerides, while enhancing high-density lipoprotein (HDL) function, which has immunoregulatory properties such as endotoxin neutralization and macrophage cholesterol efflux. Regarding protein metabolism, exercise triggers the expression of heat shock proteins (HSPs) that act as intracellular chaperones and extracellular immune signals. Exercise also promotes the secretion of myokines (e.g., IL-6, IL-15, irisin, FGF21) from skeletal muscle, which modulate immune responses, facilitate T cell and macrophage function, and support immunological memory. Furthermore, exercise reshapes amino acid metabolism, particularly of glutamine, arginine, and branched-chain amino acids (BCAAs), thereby influencing immune cell proliferation, biosynthesis, and signaling. Leucine-mTORC1 signaling plays a key role in T cell fate, while arginine metabolism governs macrophage polarization and T cell activation. In summary, this review underscores the complex, bidirectional relationship between exercise and immune function, orchestrated through metabolic remodeling. Future research should focus on causative links among specific metabolites, signaling pathways, and immune phenotypes, as well as explore the epigenetic consequences of exercise-induced metabolic shifts. This integrated perspective advances understanding of exercise as a non-pharmacological intervention for immune regulation and offers theoretical foundations for individualized exercise prescriptions in health and disease contexts.

Ischemic stroke(IS)is a devastating neurological disease commonly around the world.Although modern medicine has recognized the confined mechanisms in the pathological process of cerebral ischemia,it has never been enough for the treatment of IS.Recent studies have confirmed the vital role of mitochondrial dysfunction in neuronal injury after cerebral ische-mia,thereby exerting a potential target for prevention and treat-ment of IS.Herein,we review the main molecular mechanisms of neuronal injury and death by mitochondrial dyshomeostasis under the condition of ischemia/hypoxia,especially mitochon-drial permeability transition pore opening,oxidative stress and apoptotic signaling.Given remodeling of mitochondrial function as a new idea for the management of IS,some emerging strate-gies containing mitochondrial antioxidant,mitophagy regulation and mitochondrial transfer also raise concern in this paper.

Objective To explore the value of serum D-dimer(D-D),fibrinogen(FIB),platelet(PLT),C-reactive pro-tein(CRP)and tissue plasminogen activator inhibitor(PAI)-1 levels in predicting lower extremity deep vein thrombosis(DVT)after hip joint surgery in the elderly.Methods A retrospective analysis was performed on 165 elderly patients with hip joint surgery admitted from February 2020 to May 2022,including 89 males and 76 females,aged from 60 to 75 years old with an average of(66.43±5.48)years,and there were 102 cases of femoral neck fracture and 63 cases of femoral head necrosis.Serum levels of D-D,FIB,PLT,CRP and PAI-1 tests were performed in all patients within 24 hours after admission,and the patients were divided into DVT group and non-DVT group according to whether they developed DVT.Results The levels of D-D,FIB,PLT,CRP,and PAI-1 in the DVT group were higher than those in the non-DVT group(P＜0.001).Spearman analysis showed that DVT was positively correlated with PLT,CRP,D-D,FIB,and PAI-1 levels(r=0.382,0.213,0.410,0.310,0.353,all P＜0.001).The results of binary Logistic regression analysis showed that D-D and PLT were independent factors affecting the occurrence of DVT(OR=0.038,0.960,P=0.032,0.011).The area under curve(AUC)of D-D,FIB,PLT,CRP,PAI-1,and the five combined predictions for DVT were 0.843,0.692,0.871,0.780,0.819,and 0.960,respectively.The AUC of the five combined predictions was higher than that of the single prediction(P＜0.05).Conclusion D-D,FIB,PLT,CRP and PAI-1 are effective in predicting DVT after hip surgery in the elderly,and the combined prediction of the five factors has higher effi-cacy.
