The theory of constitution in traditional Chinese medicine （TCM） has emerged as a new discipline in recent years. Constitution plays a vital role in the onset，progression，transformation，and prognosis of diseases. At present，some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation"，in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology，onset，pathogenesis，syndrome differentiation，and treatment. Against this background，the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution，aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models，thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions，diseases，and syndromes，but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods，the study evaluates the model's validity，reliability，and practicality，with the aim of opening new avenues for future research in TCM and promoting the development of the field.

Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components， characterized by recurrent episodes of wheezing， shortness of breath， chest tightness， and coughing， significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway， as a crucial hub in intracellular signaling， is widely involved in the regulation of cell growth， proliferation， survival， metabolism， and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant， specifically in promoting airway inflammation， mediating epithelial mesenchymal transition， accelerating airway remodeling， regulating cell autophagy， inducing mucus hypersecretion， and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway， including activators such as cysteine proteinase inhibitor 1（CST1）， found in inflammatory zone 1（FIZZ1） and free fatty acid receptor 1（FFAR1）， and inhibitors such as human β-defensin-3（hBD-3）， disintegrins， metalloproteinase 33（ADAM33） and interleukin-27（IL-27）， and initially revealed the potential molecular mechanisms of traditional Chinese medicine（TCM） in asthma intervention. Based on this， the authors systematically summarized the efficacy and specific mechanisms of TCM monomers， compounds， and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis， aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment， offering innovative insights for clinical research and drug development of asthma.

Objective To analyze the impact of chronic obstructive pulmonary disease(COPD)on coronary plaque burden in elderly patients.Methods A total of 120 COPD patients admitted to the Hongqi Hospital Affiliated to Mudanjiang Medical University from January 2022 to December 2024 were prospectively enrolled and served as the COPD group.Another 120 healthy volunteers were recruited as the control group during the same period.The general clinical data and coronary plaque burden were compared between the two groups.Pearson linear correlation analysis was used to investigate the correlation between forced expiratory volume in the first second(FEV1)and coronary plaque burden as well as left ventricular ejection fraction(LVEF).Multiple linear regression analysis was employed to identify the influencing factors of total coronary plaque bur-den and calcified plaque burden.Results The COPD group had significantly larger smoking ratio and higher levels of high-sensitivity C-reactive protein(hs-CRP)and IL-6,but obviously lower LVEF and FEV1 levels than the control group(P＜0.01).Notably increased total coronary plaque burden(38.30±8.22 vs 24.61±5.56,P＜0.01),calcified plaque burden(21.11±6.57 vs 12.54±3.65,P＜0.01)and non-calcified plaque burden(17.19±5.39 vs 12.07±3.92,P＜0.01)were observed in the COPD group than the control group.FEV1 was negatively correlated with coro-nary plaque burden,calcified plaque burden,and non-calcified plaque burden,and positively corre-lated with LVEF(P＜0.01).Multiple linear regression analysis showed that FEV1 and IL-6 were influencing factors for both total coronary plaque burden(P＜0.01)and coronary calcified plaque burden(P＜0.01),and FEV1 was an influencing factor of non-calcified plaque burden in coronary arteries(P＜0.01).Conclusion COPD promotes the development of coronary plaque burden.So,for COPD patients,it is necessary to strengthen the monitoring and early prevention of coronary plaque burden.

Objectives:To evaluate the hemodynamic impact of different bypass grafting methods on the left anterior descending(LAD)artery using computational fluid dynamics,providing a theoretical basis for optimizing coronary artery bypass grafting.Methods:A patient-specific 3D coronary model was constructed using SimVascular software,including an in-situ internal mammary artery graft(model 1)and three free grafts of varying diameters(model 2:2 mm internal mammary artery free graft;model 3 and model 4:3 mm and 4 mm great saphenous vein free grafts).The hemodynamic parameters of the native artery and grafts were compared among the four bypass grafting models.Results:All four bypass grafting models supply sufficient blood flow for the severely stenosed LAD.LAD flow was slightly lower in the model 1.Free internal mammary artery grafts showed higher flow and wall shear stress.4 mm great saphenous vein free grafts presented with maximum flow but lowest shear stress,3 mm great saphenous vein free grafts offered better hemodynamic stability.Conclusions:Computational fluid dynamics analysis indicates that free internal mammary grafts could provide superior hemodynamics,while larger grafts result in lower shear stress,which might affect long-term graft patency.These findings thus provide experimental evidences useful for optimizing LAD bypass strategies.

Objective To investigate the factors influencing the persistence of residual low back pain following percutaneous vertebroplasty(PVP)in patients with osteoporotic vertebral fractures(OVF),in order to provide a scientific basis for clinical intervention strategies.Methods A retrospective analysis was conducted on data from 1 120 patients diagnosed with OVF who received PVP treatment between July 2020 and June 2025.Among them,61 patients who experienced residual low back pain in the early postoperative period(defined as 2 days to 1 month after surgery)with a postoperative visual analog scale(VAS)score greater than 3 points were selected as the observation group.An additional 61 control subjects were matched to the observation group at a 1∶1 ratio based on age(±5 years),gender,and preoperative bone mineral density(±0.5 standard deviation).Univariate and logistic regression analyses were subsequently performed to evaluate potential influencing factors.Results Univariate analysis revealed statistically significant differences between the two groups with respect to preoperative thoracolumbar fascia injury(TFI),MRI-detected liquefaction signals in the affected vertebrae,the number of involved vertebrae(≥2),and suboptimal bone cement distribution(P<0.05).Multivariate regression analysis confirmed that these factors were independent risk factors,with corresponding odds ratios(ORs)of 5.378,6.111,3.245,and 2.890(all P<0.05).The area under the curve(AUC)of the predictive model was 0.929,indicating a high level of predictive accuracy.Conclusion Preoperative TFI,MRI-demonstrated liquefaction signals in the affected vertebrae,the presence of multiple responsible vertebrae,and suboptimal bone cement distribution may contribute to an increased risk of early residual low back pain following PVP.
