Chronic heart failure (CHF) is a complex clinical syndrome caused by ventricular dysfunction, with mitochondrial energy metabolism disorder being a critical factor in disease progression. Heart-Yang deficiency syndrome, as the core pathogenesis of CHF, persists throughout the disease course. Insufficiency of heart-Yang leads to weakened warming and propelling functions, resulting in the accumulation of phlegm-fluid, blood stasis, and dampness. This eventually causes Qi stagnation with phlegm obstruction and blood stasis with water retention, forming a vicious cycle that exacerbates disease progression. According to the theory of reinforcing Yang, the clinical experience of the traditional Chinese medicine (TCM) master Tang Zuxuan in treating CHF with heart-Yang deficiency syndrome, and achievements from molecular biological studies, this study innovatively proposes an integrated research framework of "TCM syndrome differentiation and staging-mitochondrial metabolism mechanisms-intervention with Yang-reinforcing prescriptions" which is characterized by the integration of traditional Chinese and Western medicine. Heart-Yang deficiency syndrome is classified into mild (Stage Ⅰ-Ⅱ), severe (Stage Ⅲ), and critical (Stage Ⅳ) stages. The study elucidates the precise correlations between the pathogenesis of each stage and mitochondrial metabolism disorders from theoretical, pathophysiological, and therapeutic perspectives. The mild stage is characterized by impaired biogenesis and substrate-utilization imbalance, corresponding to heart-Yang deficiency and phlegm-fluid aggregation. Linggui Zhugantang and similar prescriptions can significantly improve the expression of peroxisome proliferator-activated receptor gamma co-activator-1α(PGC-1α)/silent information regulator 2 homolog 1 (SIRT1) and ATPase activity. The severe stage centers on oxidative stress and structural damage, reflecting Yang deficiency with water overflow and phlegm-blood stasis intermingling. At this stage, Zhenwu Tang and Qiangxin Tang can effectively mitigate oxidative stress damage, increase adenosine triphosphate (ATP) content, and repair mitochondrial structure. The critical stage arises from calcium overload and mitochondrial disintegration, leading to the collapse of Yin-Yang equilibrium. At this stage, Yang-restoring and crisis-resolving prescriptions such as Fuling Sini Tang and Qili Qiangxin capsules can inhibit abnormal opening of the mitochondrial permeability transition pore (MPTP), reduce cardiomyocyte apoptosis rate, and protect mitochondrial function. By summarizing the characteristics of mitochondrial energy metabolism disorders at different stages of CHF, this study explores the application of the theory of reinforcing Yang in treating heart-Yang deficiency syndrome and provides new insights for the clinical diagnosis and treatment of CHF.

ObjectiveTo explore the mechanism of ventricular remodeling mediated by the p38 mitogen-activated protein kinase (MAPK)/nuclear factor kappa B (NF-κB) signaling pathway in the rat model of chronic heart failure (CHF) with heart-blood stasis syndrome, as well as the intervention effect of Danhong injection. MethodsIn vivo experiment: SPF-grade male SD rats were assigned via the random number table method into 4 groups: Sham operation, model, captopril (8.8 mg·kg-1), and Danhong injection (6.0 mL·kg-1). The model of CHF with heart-blood stasis syndrome was established by abdominal aortic constriction, and the sham operation group only underwent laparotomy without constriction. All the groups were treated continuously for 15 days. The tongue color of rats was observed. Echocardiography, hemorheology, heart mass index (HMI), and left ventricular mass index (LVMI) were measured. Hematoxylin-eosin (HE) staining and Masson staining were performed to observe the pathological and fibrotic changes of the myocardial tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to quantify the levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), interleukin-6 (IL-6), angiotensin Ⅱ (AngⅡ), tumor necrosis factor-α (TNF-α), and Creactive protein (CRP) in the serum, as well as the levels of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in the myocardial tissue. Western blot was used to quantify the protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 in the myocardial tissue. In vitro experiment: H9C2 cardiomyocytes were treated with 1×10-6 mol·L-1 AngⅡ to establish a model of myocardial hypertrophy. H9C2 cardiomyocytes were allocated into normal, model, inhibitor + Danhong injection, Danhong injection (20 mL·L-1), and inhibitor (SB203580, 5 μmol·L-1) groups. CCK-8 assay was used to detect the viability of H9C2 cardiomyocytes. Rhodamine-labeled phalloidin staining was used to reveal the area of cardiomyocytes. Real-time PCR was performed to determine the mRNA levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). Western blot was used to assess the protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65. ResultsIn vivo experiment: Compared with the sham operation group, the model group showed purplish-dark tongue with decreased R, G, B values of the tongue surface (P<0.01), increased whole blood viscosity (at low, medium, and high shear rates) (P<0.01), decreased left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) (P<0.01), increased left ventricular end-diastolic diameter (LVIDd), left ventricular end-systolic diameter (LVIDs), and left ventricular posterior wall thickness at end-diastole (LVPWd) (P<0.01), raised LVMI and HMI (P<0.01), and elevated levels of NT-proBNP, TNF-α, IL-6, and CRP in the serum and MMP-2 and MMP-9 in the myocardial tissue (P<0.01). The HE and Masson staining of the myocardial tissue showed compensatory myocardial hypertrophy, fibrosis, and massive inflammatory cell infiltration in the model group. Additionally, the model group presented up-regulated protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 in the myocardial tissue (P<0.01). Compared with the model group, each administration group showed increased R, G, B values of the tongue surface (P<0.05, P<0.01), decreased whole blood viscosity (at low, medium, and high shear rates) (P<0.05, P<0.01), increased LVEF and LVFS (P<0.01), decreased LVIDd, LVIDs, and LVPWd (P<0.05, P<0.01), declined LVMI and HMI (P<0.05, P<0.01), and lowered levels of NT-proBNP, TNF-α, IL-6, and CRP in the serum and MMP-2 and MMP-9 in the myocardial tissue (P<0.01). HE and Masson staining showed alleviated compensatory myocardial hypertrophy, reduced fibrosis, and decreased expression of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 in the myocardial tissue (P<0.01). In vitro experiment: When the concentration of Danhong injection reached 20 mL·L-1, the survival rate of H9C2 cardiomyocytes was the highest (P<0.01). Compared with the normal group, the model group showed up-regulated mRNA levels of ANP and BNP (P<0.01), increased relative cell surface area (P<0.01), and raised protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 (P<0.01). Compared with the model group, each administration group showed down-regulated mRNA levels of ANP and BNP (P<0.01), reduced relative cell surface area (P<0.05, P<0.01), and down-regulated protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 (P<0.05, P<0.01). ConclusionDanhong injection can regulate ventricular remodeling through the p38 MAPK/NF-κB pathway, thereby exerting a protective effect on the rat model of CHF with heart-blood stasis syndrome.

Hepatic fibrosis is a reversible pathological process in various chronic liver diseases and is closely associated with the development and progression of severe liver diseases such as liver cirrhosis and hepatocellular carcinoma, and it has emerged as a significant global health challenge. In recent years, studies have shown that histone lactylation, a newly discovered epigenetic modification, actively participates in regulating the progression of hepatic fibrosis. This article systematically reviews the core regulatory effect of histone lactylation modification in the interaction between inflammatory microenvironment and hepatic fibrosis, in order to clarify the cascade regulatory mechanism of “inflammation-hepatic fibrosis” and provide new insights for early diagnosis, targeted intervention, and prevention of malignant transformation in hepatic fibrosis.

Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Objective:
This study compared the effects of personalized exercise versus acupuncture on multidimensional cognitive function in individuals at high risk for stroke with mild cognitive impairment (MCI).
Methods:
A randomized controlled trial enrolled 200 stroke-risk adults aged 50−80 years. Ninety participants diagnosed with MCI (MMSE, HIS, CDR criteria) were randomly assigned to exercise (n = 30), acupuncture (n = 30), or control (n = 30) groups. Interventions lasted 6 months. Cognitive outcomes (MMSE, Raven’s Progressive Matrices, Digit Symbol Substitution Test, Animal Fluency, Rey-Osterrieth test, Stroop test) were assessed before and after intervention. Multivariate regression identified risk factors for MCI. ANOVA was used for group comparisons.
Results:
Hypertension (aOR = 1.5) and diabetes (aOR = 1.3) were significant risk factors for MCI. After intervention, the exercise group showed the largest MMSE improvement (Δ = 5.0), compared with acupuncture (Δ = 3.0) and control (Δ = 1.0) (p < 0.001). Exercise produced greater gains in non-verbal reasoning (31.8% vs. 26.1% in acupuncture, p < 0.01). Acupuncture more effectively enhanced processing speed and attention (DSST: Δ = 26 vs. Δ = 20 in exercise, p = 0.03) and executive function (Stroop interference time: Δ = 16 vs. Δ = 15 seconds in exercise, p = 0.04). Both interventions significantly improved verbal fluency (p < 0.001), with larger benefits in those with baseline MMSE ≤ 20.
Conclusion
Hypertension and diabetes are key risk factors for MCI in stroke-prone individuals. Exercise yields greater improvement in global cognition and memory, whereas acupuncture is more effective for enhancing attention and executive function. Both modalities benefit verbal fluency, particularly in lower-functioning participants.

Purpose:
The genomic characteristics of uterine sarcomas have not been fully elucidated. This study aimed to explore the genomic landscape of the uterine sarcomas (USs).
Materials and Methods:
Comprehensive genomic analysis through RNA-sequencing was conducted. Gene fusion, differentially expressed genes (DEGs), signaling pathway enrichment, immune cell infiltration, and prognosis were analyzed. A deep learning model was constructed to predict the survival of US patients.
Results:
A total of 71 US samples were examined, including 47 endometrial stromal sarcomas (ESS), 18 uterine leiomyosarcomas (uLMS), three adenosarcomas, two carcinosarcomas, and one uterine tumor resembling an ovarian sex-cord tumor. ESS (including high-grade ESS [HGESS] and low-grade ESS [LGESS]) and uLMS showed distinct gene fusion signatures; a novel gene fusion site, MRPS18A–PDC-AS1 could be a potential diagnostic marker for the pathology differential diagnosis of uLMS and ESS; 797 and 477 uterine sarcoma DEGs (uDEGs) were identified in the ESS vs. uLMS and HGESS vs. LGESS groups, respectively. The uDEGs were enriched in multiple pathways. Fifteen genes including LAMB4 were confirmed with prognostic value in USs; immune infiltration analysis revealed the prognositic value of myeloid dendritic cells, plasmacytoid dendritic cells, natural killer cells, macrophage M1, monocytes and hematopoietic stem cells in USs; the deep learning model named Max-Mean Non-Local multi-instance learning (MMN-MIL) showed satisfactory performance in predicting the survival of US patients, with the area under the receiver operating curve curve reached 0.909 and accuracy achieved 0.804.
Conclusion
USs harbored distinct gene fusion characteristics and gene expression features between HGESS, LGESS, and uLMS. The MMN-MIL model could effectively predict the survival of US patients.

Objective To elucidate the mechanisms of trauma-induced coagulopathy(TIC),clarify the specific pathogenic factors and pathophysiological processes,and discover the effective diagnostic indicators and therapeutic targets.Methods Transcriptomic data of traumatic hemorrhagic shock patients were obtained from the Gene Expression Omnibus(GEO)to identify differentially expressed genes(DEGs).Coagulation-related genes(CRGs)from the Kyoto Encyclopedia of Genes and Genomes(KEGG)were intersected with DEGs.Machine learning algorithms,including least absolute shrinkage and selection operator(LASSO)and random forest(RF),were applied to identify key genes.The CIBERSORT algorithm was used to analyze the correlation between key genes and immune cell infiltration.Through consensus clustering,subtype analysis was conducted on trauma patients to compare the infiltration of immune cells.A rat model of traumatic hemorrhagic shock was established to validate coagulation function and the expression of key genes.Results The dataset included samples from 17 healthy controls and 478 patients with traumatic hemorrhagic shock.A total of 6 315 DEGs were identified under the screening criterion of corrected P<0.05.Gene set enrichment analysis(GSEA)showed that the up-regulated DEGs were significantly enriched in the glucose metabolism pathway,while the down-regulated DEGs were enriched in the immune reaction-related pathways.Through cross-analysis of DEGs and CRGs,a total of 65 differentially expressed coagulation-related genes(DE-CRGs)were screened out.GO functional enrichment showed that these genes were mainly located in secreting granular membranes and platelet α-granules,and were involved in physiological processes such as blood coagulation,regulation of body fluid levels,and wound healing.KEGG pathway analysis revealed that these genes were significantly enriched in pathways such as platelet activation,complement and coagulation cascade reactions,Rap1 signaling pathway,and human cytomegalovirus infection.Six key DE-CRGs were identified through machine learning.Receiver operating characteristic(ROC)curve analysis indicated that these genes had good diagnostic efficacy.CIBERSORT analysis revealed a significant correlation between key genes and immune cell infiltration.Patients were classified into two subtypes based on the six key genes:subtype A was rich in CD8+T cells and activated NK cells,presented an immune-active state;subtype B was mainly composed of monocytes and resting NK cells,with insufficient activation of immune pathways.Animal experiments on rats showed that hemorrhagic shock can lead to coagulation dysfunction.The results of qRT-PCR further confirmed that the expression trend of key genes was consistent with the results of bioinformatics analysis.Conclusion In this study,through transcriptomics and machine learning methods,six key genes closely related to TIC were systematically screened out,namely GNA13,PIK3R3,ITGAM,MAPK14,PPP1CC and LYN,and their close connections with coagulation function and immune infiltration were revealed.Animal experiments have further verified the value of these genes as potential diagnostic and therapeutic targets.

Chinese Journal of Tissue Engineering Research 2025;29(35):7589-7600
BACKGROUND:SOX5 is an important transcription factor of the SRY-related HMG-box(SOX)family,which plays a key role in regulating the expression of genes related to bone development and remodeling,especially during osteoblast differentiation and chondrocyte maturation,through its unique HMG box DNA structural domains in concert with SOX6 and SOX9.In addition,the expression and activity of SOX5 and its family are regulated by a variety of diseases and different forms of exercise,among other factors,suggesting that SOX5 and its family have the potential to be effective as drugs and therapeutics to ameliorate related diseases in the future.OBJECTIVE:To provide new perspectives for future research on SOX5 and to provide scientific basis for the application of exercise intervention and drug therapy in the prevention and treatment of bone diseases.METHODS:CNKI and PubMed databases were searched for relevant literature published from 2001 to June 2024,and the search terms were"SRY-related HMG-box5,SOX5,Bone"in Chinese and English,respectively.After screening,analysis and summarization,105 articles were included in the final review.RESULTS AND CONCLUSION:(1)Role of SOX5 in bone development:SOX5 is an important member of the SOX family,which plays a central role in the regulation of skeletal development,bone metabolism and cartilage formation.In synergy with SOX6 and SOX9,SOX5 activates gene expression in osteoblasts and chondrocytes by binding to specific DNA sequences to regulate bone formation and bone remodeling.(2)Abnormal expression of SOX5 is closely related to bone and joint diseases such as chondrodysplasia,osteoporosis and osteoarthritis,suggesting that it may be a key regulator of these diseases.Currently,a variety of drugs may be used to treat bone metabolism-related diseases by regulating SOX5 and its family,and upregulation of SOX5 in mesenchymal stem cells may be effective in improving the symptoms of bone metabolism disease patients in bone tissue engineering.(3)Exercise may effectively prevent osteoporosis and related bone diseases by enhancing bone metabolism and promoting osteoblast differentiation and bone density increase.This mechanism of action may be related to the specific regulatory mechanism of SOX5,especially in different types,intensities and durations of exercise need to be further explored and studied.In conclusion,SOX5 has an important regulatory role in bone development,chondrogenesis,and prevention of bone diseases,and its activity is regulated by a variety of factors,while exercise intervention provides a new scientific basis for the treatment of bone diseases.
