ObjectiveTo establish an animal model of atrial fibrillation(AF) that accurately reflects the phlegm-heat and blood stasis(TRYZ) pathogenesis in traditional Chinese medicine. MethodsForty SPF-grade SD rats were randomly assigned using a random number table to the following groups:the control group, the TRYZ+AF group,the AF group and the TRYZ group, with ten rats in each group. The TRYZ+AF and TRYZ groups underwent a high-fat diet combined with intraperitoneal lipopolysaccharide(LPS) injection to simulate the pathological alterations of TRYZ syndrome. Groups TRYZ+AF and AF were induced with acetylcholine-calcium chloride(Ach-CaCl2) via caudal vein injection to induce AF. The control group received no intervention and was maintained under normal conditions. The modeling period lasted 3 weeks. Electrocardiography was used to assess AF episodes and duration, echocardiography evaluated left atrial dimensions and cardiac function, fully automated biochemical analyzer measured the levels of total cholesterol(TC), triglycerides(TG), high-density lipoprotein cholesterol(HDL-C) and low-density lipoprotein cholesterol(LDL-C), hemoreometer analyzed the whole blood viscosity, plasma viscosity, and whole blood reduced viscosity, a coagulation analyzer assessed prothrombin time(PT), activated partial thromboplastin time(APTT), thrombin time(TT), and fibrinogen(FIB), enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of C-reactive protein(CRP), interleukin(IL)-1β, IL-6, IL-17, tumour necrosis factor(TNF)-α, matrix metalloproteinase-9(MMP-9), galectin-3(Gal-3), Collagen Ⅰ, and α-smooth muscle actin(α-SMA). Hematoxylin-eosin(HE) staining and Masson's trichrome staining were used to analyze pathological changes in atrial myocardium, Western blot was employed to detect MMP-9, Collagen Ⅰ and α-SMA protein expression in myocardial tissue, real-time quantitative polymerase chain reaction(Real-time PCR) evaluated fibrous factor gene expression levels. Changes in the TRYZ syndrome were assessed via body weight, tongue color[red(R), green(G), and blue(B)], and rectal temperature. Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to detect differential metabolites between the control group and the TRYZ+AF group. ResultsFollowing three weeks of sustained modeling, compared with the control group, rats in the TRYZ+AF and the TRYZ groups exhibited reduced body weight, dry faeces, elevated rectal temperature, dark red tongue, decreased RGB values on the tongue surface, and markedly elevated TC and LDL-C levels(P<0.05, P<0.01). The TRYZ+AF, TRYZ, and AF groups exhibited significantly decreased TT, APTT and PT, along with markedly elevated whole blood viscosity and FIB(P<0.05, P<0.01). Rats in the TRYZ+AF and AF groups exhibited AF rhythm, markedly decreased heart rate, prolonged RR intervals, enlarged left atrium, and significantly reduced ejection fraction and shortening fraction(P<0.05, P<0.01). Serum levels of CRP, IL-1β, IL-6, IL-17, TNF-α, MMP-9, Gal-3, Collagen Ⅰ, and α-SMA were elevated in rats from the TRYZ+AF, TRYZ, and AF groups compared to the control group, with the most pronounced increase observed in the TRYZ+AF group(P<0.05, P<0.01). Histopathology revealed that the collagen fiber deposition in the atrial of rats in the TRYZ+AF, TRYZ and AF groups was higher than that in the control group(P<0.05, P<0.01). Western blot and Real-time PCR results further demonstrated that the protein and mRNA expression levels of MMP-9, Collagen Ⅰ and α-SMA in the myocardial tissue of the TRYZ+AF group were higher than those in the other three groups(P<0.05, P<0.01). Metabolomic analysis revealed 173 differentially expressed metabolites in the TRYZ+AF group and the control group, primarily enriched in pathways such as glycerophospholipid metabolism and glycolysis/gluconeogenesis. ConclusionThis study successfully establishes a rat model of AF integrated with the TRYZ syndrome, demonstrating the pathological process where the interactions of phlegm, heat and stasis jointly trigger tremor, this provides a reliable experimental tool for in-depth research into the biological basis of this disease syndrome.

To explore the advantages of traditional Chinese medicine (TCM) and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications (DMC), refine key pathophysiological insights and treatment principles, and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine, hosted by the China Association of Chinese Medicine, was held in Beijing, 2024. Experts in TCM, Western medicine, and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis, diagnostic and treatment challenges, and mechanism research related to DMC, ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development, research prioritization, and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM, strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Chronic liver diseases are a group of diseases in which the liver is subjected to a variety of injuries over a long period of time, resulting in irreversible pathological changes that last longer than 6 months. Emodin (EMO) is a natural anthraquinone derivative derived from Rheum officinale, and its pharmacological effect has been extensively studied, exhibiting a variety of biological properties and involving multiple signaling molecules and pathways. Western medicine or surgical treatment is currently the main treatment regimen for chronic liver diseases, and the advance in treatment is limited by various reasons such as side effects and high costs. Due to its natural origin and efficacy, EMO has unique advantages in the treatment of chronic liver diseases and has now become a research hotspot. This article summarizes the therapeutic effect of EMO on chronic liver diseases and its mechanism, in order to provide a certain scientific basis for the traditional Chinese medicine treatment of chronic liver diseases and the development of drugs in clinical practice.

ObjectiveTo investigate the effects of modified Buyang Huanwu Tang on cerebral ischemia-reperfusion injury (CI/RI) in mice via the PTEN-induced putative kinase 1/E3 ubiquitin ligase (PINK1/Parkin) signaling pathway-mediated mitophagy, and to explore the underlying mechanism by which modified Buyang Huanwu Tang improves CI/RI. MethodsSeventy-two male C57BL/6J mice were randomly divided into six groups (n = 12 per group): Sham-operated group, middle cerebral artery occlusion/reperfusion (MCAO/R) model group, low-, medium-, and high-dose modified Buyang Huanwu Tang groups (8.84, 17.68, 35.36 g·kg-1·d-1), and an aspirin group (13.00 mg·kg-1·d-1). Neurological deficit scores were assessed using the Zea-Longa method. Cerebral infarct volume ratio was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Histopathological changes and neuronal injury in brain tissues were observed using hematoxylin-eosin (HE) staining and Nissl staining. Apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Mitochondrial ultrastructure in brain tissue was observed by transmission electron microscopy (TEM). Serum levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were determined by enzyme-linked immunosorbent assay (ELISA). The mRNA and protein expression levels of PINK1, Parkin, microtubule-associated protein 1 light chain 3B (LC3B, LC3Ⅱ/Ⅰ), and p62 in brain tissues were detected by real-time quantitative reverse transcription PCR (Real-time PCR) and Western blot, respectively. ResultsCompared with the sham-operated group, the MCAO/R model group showed significantly increased neurological deficit scores and cerebral infarct volume ratios (P<0.01). Severe cortical injury on the infarct side was observed, characterized by decreased neuronal density, cytoplasmic vacuolation, nuclear pyknosis, a marked reduction in Nissl bodies, dissolution of Nissl bodies in the cytoplasm of some pyramidal neurons, and blurred cellular boundaries. The number of TUNEL-positive cells increased significantly (P<0.01). Mitochondria exhibited cristae membrane rupture and matrix vacuolation, with rupture of the outer mitochondrial membrane and formation of autophagosomes, the number of which increased significantly. Serum SOD activity decreased significantly (P<0.01), while MDA content increased significantly (P<0.01). In infarcted brain tissues of model mice, the relative mRNA expression and protein levels of PINK1, Parkin and LC3B were significantly increased (P<0.05, P<0.01), whereas p62 mRNA and protein expression were significantly decreased (P<0.05, P<0.01), showing statistical significance. Compared with the model group, all treatment groups showed significantly decreased neurological deficit scores and cerebral infarct volume ratios (P<0.01). Neuronal density increased significantly, cytoplasmic vacuolation was alleviated, nuclear morphology tended to be more regular and clearer, Nissl body density increased significantly with reduced dissolution and improved contour clarity. The mitochondrial cristae structure was partially restored, with some mitochondria showing autophagosome encapsulation, and the degree of mitochondrial damage was alleviated. Serum SOD activity increased significantly (P<0.01), while MDA content decreased significantly. The mRNA and protein expression levels of PINK1, Parkin, and LC3Ⅱ/Ⅰ were significantly increased (P<0.05, P<0.01), while p62 mRNA and protein expression in the low- and medium-dose modified Buyang Huanwu Tang groups were significantly decreased (P<0.05, P<0.01), showing statistical significance. ConclusionModified Buyang Huanwu Tang can upregulate the protein expression levels of PINK1, Parkin, and LC3Ⅱ/Ⅰ and downregulate p62 protein expression, suggesting that it may improve CI/RI by regulating the expression of proteins related to the PINK1/Parkin signaling pathway. Regulation of the mitophagy pathway may be one of the mechanisms by which modified Buyang Huanwu Tang alleviates CI/RI in mice.

ObjectiveTo investigate the protective effect of α-ketoglutarate (α-KG) on hepatic lipid deposition in offspring caused by arsenic exposure during pregnancy. Methods8-week-old institute of cancer research (ICR) mice were mated in a ratio of 2∶1 between females and males, and the detection of vaginal plugs confirmed pregnant. A total of 32 pregnant mice were randomly divided into four groups: control group, arsenic group, α-KG group, arsenic+α-KG group. On gestational day 0-16 (GD0-GD16), the arsenic and arsenic+α-KG groups were exposed to sodium arsenite (NaAsO2 ,15 mg/L) in drinking water everyday, and the α-KG and arsenic+α-KG groups were gavaged with α-KG (2 g/kg) everyday. On GD16, pregnant mice were euthanized to collect fetal liver, and fetal body weight and crown-rump length were measured. Gene expression differences between the control group and the arsenic group were analyzed by transcriptome. The total triglycerides (TGs) and subtypes in fetal liver were detected by liquid chromatography tandem mass spectrometry (LC-MS/MS). Oil red O staining was used to observe the histopathological changes in the liver. Quantitative polymerase chain reaction (qPCR) was used to detect the expression level of genes related to lipid synthesis, transport, and degradation, and phosphatidylinositol 3' -kinase/ protein kinase B (PI3K/AKT) in the liver of fetus. ResultsTranscriptomics analysis showed that 2 144 genes were downregulated and 1 675 genes were upregulated in the arsenic exposed fetal liver; body weight and crown-rump length were reduced (PTuKey<0.05); the level of hepatic TGs was elevated in arsenic group (PTuKey<0.05); oil-red O staining showed a significant increase in lipid droplets in arsenic group (PTuKey<0.01); the expression of lipid synthesis-related genes were significantly upregulated (PTuKey<0.05); the expression of β-oxidation-related genes and lipid degradation-related genes were downregulated (PTuKey<0.05); the expression of PI3K, AKT decreased(PTuKey<0.05). Compared with the arsenic group, the body weight and crown-rump length of fetus increased in the arsenic+α-KG group (PTuKey<0.05); the level of hepatic TGs decreased in the arsenic+α-KG group (PTuKey<0.05); oil red O staining showed lipid droplets significantly decreased (PTuKey<0.01); the expression of lipid synthesis-related genes were downregulated (PTuKey<0.05), the expression of β-oxidation-related genes and lipid degradation-related genes were upregulated (PTuKey<0.05); the expression levels of PI3K and AKT increased (PTuKey<0.05). Conclusionα-KG alleviated hepatic lipid deposition in offspring exposed to arsenic during pregnancy through activating PI3K/AKT signaling pathway.

Objective: To explore the application effectiveness of healthcare failure mode and effect analysis (HFMEA) in optimizing intelligent blood logistics transport pathways for safety assurance. Methods: Data from 1 851 cases of intelligent blood logistics transport were collected between September 2023 and March 2025. Based on the implementation phases of HFMEA measures, the cases were divided into a control group (n=120), observation group 1 (n=219), and observation group 2 (n=1 512). Through systematic analysis of the transport processes, hazard scoring and decision tree analysis were conducted for each process, and phased optimization measures were implemented for high-risk failure modes. Results: The transport duration of intelligent blood logistics was 35.5 (20.8, 71.1) min in the control group, 25.1 (10.9, 40.7) min in observation group 1, and 9.9 (4.2, 44.5) min in observation group 2. Observation group 2 exhibited significantly shorter transport time compared to both observation group 1 and the control group, with statistically significant differences between groups (P<0.000 1). Conclusion: The implementation of HFMEA-driven measures significantly reduced intelligent blood logistics transport duration, thereby fostering the evolution of smart hospital ecosystems while enhancing healthcare service quality and operational efficiency.

ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and the severity of intrauterine adhesions (IUA). MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions (TCRA) from December 2019 to March 2025. Based on the American Fertility Society (AFS) classification, patients were divided into mild (n=61), moderate (n=225), and severe (n=94) groups. NLR, PLR, and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR, PLR, and SII were significantly higher in the severe IUA group compared to the mild group (P<0.05), with SII showing the strongest predictive ability (OR=1.004, P=0.001). The number of intrauterine procedures was an independent risk factor (OR=1.27/level, P=0.016). The predictive model [Logit(P)=-0.676+0.241×operation times+0.004×SII] effectively identified severe IUA cases. ConclusionInflammatory markers (particularly SII) are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

Objective:
To explore the latent profile characteristics of regulatory emotional self-efficacy and its relationship with non-suicidal self-injurious (NSSI) behavior among junior and senior high school students, so as to provide a basis for effectively reducing NSSI behaviors.
Methods:
From April to October 2023, a total of 1 217 junior and senior high school students were selected from Tongren City, Zunyi City and Qiannan Prefecture of Guizhou Province by stratified cluster random sampling method. The Scale of Regulatory Emotional Self-efficacy and the Adolescent Self-injury Scale were administered. Latent profile analysis (LPA) was employed to explore distinct profiles of regulatory emotional self-efficacy, and the Lanza, Tan, and Bray s method (LTB) was used to analyze the relationship between these profiles and NSSI behavior.
Results:
The prevalence rate of NSSI behavior among junior and senior high school students was 28.6%. Among males, regulatory emotional self-efficacy was categorized into two types: moderate positive expression-low negative management group (59.1%, n =353) and high efficacy group (40.9%, n =244); among females, regulatory emotional self-efficacy was classified into three categories: low efficacy group (18.4%, n =114), high positive expression-low negative management group (56.3%, n =349), and high efficacy group (25.3%, n =157). There were statistically significant differences in total NSSI scores across different potential categories of regulatory emotional self-efficacy within both males and females ( Z/H = -5.75 , 57.58, both P <0.01). The differences in NSSI prevalence rates across the potential categories of regulatory emotional self-efficacy were statistically significant for both males and females ( χ 2=38.00, 69.14, both P <0.01), and among females, the differences in NSSI prevalence rates between the high efficacy group and the low efficacy group ( χ 2=60.01) and between the high efficacy group and the high positive expression-low negative management group ( χ 2=31.34) were also statistically significant (both P < 0.016 7 ). Binary Logistic regression analysis revealed that, compared with the high efficacy group within each gender, the moderate positive expression-low negative management group among males ( OR =2.36), and both the low efficacy group and the high positive expression-low negative management group among females ( OR =6.19, 2.97), were at an increased risk of engaging in NSSI (all P <0.01).
Conclusion
Different latent profiles of regulatory emotional self efficacy among junior and senior high school students are associated with NSSI behavior.
