ObjectiveTo explore the mechanism by which the Shenfu Xiongze prescription regulates autophagy in rats with myocardial remodeling through the adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway. MethodsA rat model of myocardial remodeling induced by isoprenaline (ISO) was established. Rats were divided into the blank group,the model group,the low-,medium-, and high-dose groups of Shenfu Xiongze prescription,and the captopril group, 6 rats in each group. Except for the blank group,the rat model of myocardial remodeling was established in the other groups by intraperitoneal injection of 2.5 mg·kg-1 ISO for 3 consecutive weeks. At the same time of modeling, the low-,medium-, and high-dose groups of Shenfu Xiongze prescription were administered the corresponding doses of Shenfu Xiongze prescription solution (8.4,16.8,and 33.6 g·kg-1),and the captopril group was administered captopril solution (25 mg·kg-1). As for the blank group and the model group, the same volume of normal saline was given. The treatment was continued for 3 weeks. Echocardiography was used to observe the cardiac structure and function,and the heart weight index was detected. Masson staining and hematoxylin-eosin (HE) staining were used to observe the pathological morphology changes of myocardial tissue. The levels of interleukin-6 (IL-6) and B-type natriuretic peptide (BNP) in serum were detected by enzyme-linked immunosorbent assay (ELISA). The expression of type Ⅰ collagen (Collagen Ⅰ),type Ⅲ collagen (Collagen Ⅲ),and microtubule-associated protein 1 light chain 3 (LC3) proteins in myocardial tissue was determined by immunohistochemistry. Autophagy was observed by transmission electron microscopy. The mRNA expression of Collagen Ⅰ,Collagen Ⅲ,α-smooth muscle actin (α-SMA),LC3,yeast Atg6 homolog protein (Beclin-1),AMPK,and mTOR in myocardial tissue was detected by quantitative real-time polymerase chain reaction (real-time PCR). The protein expression of Collagen Ⅰ,α-SMA,transforming growth factor-β1 (TGF-β1),LC3,Beclin-1,p62, phosphorylation(p)-AMPK,p-mTOR,AMPK,and mTOR was detected by Western blot. ResultsCompared with the normal group,rats in the model group exhibited significantly decreased values of ejection fraction (EF) and left ventricular fractional shortening (FS) (P<0.01), significantly increased values of left ventricular end-diastolic diameter (LVIDd) and left ventricular end-systolic diameter (LVIDs) (P<0.01). Additionally, the model group also showed increased degrees of inflammatory infiltration and fibrosis of myocardial tissue, significantly elevated levels of serum IL-6 and BNP (P<0.01), significantly increased mRNA and protein levels of Collagen Ⅰ,Collagen Ⅲ,α-SMA,and mTOR (P<0.01),and markedly decreased mRNA and protein levels of LC3,Beclin-1,and AMPK (P<0.05,P<0.01). Compared with the model group, the low-,medium-, and high-dose groups of Shenfu Xiongze prescription presented significantly elevated EF and FS values (P<0.01) and lowered LVIDd and LVIDs (P<0.05). In these groups, the inflammation and fibrosis were alleviated significantly. They also exhibited decreased serum levels of IL-6 and BNP (P<0.01), significantly reduced protein expression of Collagen Ⅰ, α-SMA, TGF-β1, p62, and p-mTOR (P<0.01), significantly decreased mRNA expression of Collagen Ⅰ, Collagen Ⅲ, α-SMA, and mTOR (P<0.01), and significantly increased mRNA and protein levels of LC3, Beclin-1, and AMPK (P<0.05,P<0.01). ConclusionThe Shenfu Xiongze prescription can improve the myocardial remodeling induced by ISO in rats by regulating the autophagy level,enhance cardiac function,and reduce inflammatory and fibrotic levels. This effect may be achieved through the AMPK/mTOR signaling pathway.

ObjectiveTo observe the clinical efficacy of Sanren Runchang formula in treating constipation-predominant irritable bowel syndrome (IBS-C) by regulating the brain-gut axis and the effects of the formula on serum levels of 5-hydroxytryptamine (5-HT), vasoactive intestinal peptide (VIP), and substance P (SP). MethodsA randomized controlled design was adopted, and 72 IBS-C patients meeting Rome Ⅳ criteria were randomized into observation and control groups (36 cases).The observation group received Sanren Runchang formula granules twice daily, and the control group received lactulose oral solution daily for 4 weeks. IBS Symptom Severity Scale (IBS-SSS), IBS Quality of Life Scale (IBS-QOL), and Bristol Stool Form Scale (BSFS) were used to assess clinical symptoms, and bowel movement frequency was recorded. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were employed to evaluate psychological status. ELISA was employed to measure the serum levels of 5-HT, VIP, and SP. ResultsThe total response rate in the observation group was 91.67% (33/36), which was higher than that (77.78%, 28/36) in the control group (χ2=4.50, P<0.05). After treatment, both groups showed increased defecation frequency and BSFS scores, decreased IBS-SSS total score, abdominal pain and bloating scores, IBS-QOL health anxiety, anxiety, food avoidance, and behavioral disorders scores, SAS and SDS scores, serum 5-HT and VIP levels, and increased SP levels (P<0.05, P<0.01). Moreover, the observation group showed more significant changes in the indicators above than the control group (P<0.05, P<0.01). The SP level showed no significant difference between the two groups. During the 4-week follow-up, the recurrence rate was 5.88% in the observation group and 31.25% in the control group. No adverse events occurred in observation group, and 2 cases of mild diarrhea occurred in the control group. ConclusionSanren Runchang formula demonstrated definitive efficacy in alleviating gastrointestinal symptoms and improving the psychological status and quality of life in IBS-C patients, with a low recurrence rate. The formula can regulate serum levels of neurotransmitters such as 5-HT and VIP, suggesting its potential regulatory effect on the brain-gut axis through modulating neurotransmitters and neuropeptides. However, its complete mechanism of action requires further investigation through detection of additional brain-gut axis-related biomarkers.

ObjectiveTo address the challenges of unstructured classical Chinese expressions, nested entity relationships, and limited annotated data in famous traditional Chinese medicine(TCM) case records, this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping, aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction(CasRel) model for TCM semantics was designed, integrating a pre-trained bidirectional encoder representations from transformers(BERT) layer for classical TCM texts to enhance semantic representation, and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model, combining data augmentation and entity mapping, outperformed the pipeline-based Bert-Radical-Lexicon(BRL)-bidirectional long short-term memory(BiLSTM)-Attention model. The overall precision, recall, and F1-score across 12 relation types reached 65.73%, 64.03%, and 64.87%, which represent improvements of 14.26%, 7.98%, and 11.21% compared to the BRL-BiLSTM-Attention model, respectively. Notably, the F1-score for tongue syndrome relations increased by 22.68%(69.32%), and the prescription-syndrome relations performed the best with the F1-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts, offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation, prescription optimization, and drug compatibility, providing a methodological reference for TCM artificial intelligence research.

ObjectiveTo observe the effects of Yiqi Huoxue Jiedu formula(YHJF) on immune cell exhaustion in the spleen of septic mice and to explore and validate its potential intervention targets. MethodsMice were randomly divided into the sham-operated, model, low-dose YHJF(4.1 g·kg-1), and high-dose YHJF(8.2 g·kg-1) groups. Except for the sham-operated group, a cecal ligation and puncture(CLP) procedure was performed to establish a mouse sepsis model. The treatment groups received oral administration of the corresponding doses, while the sham-operated and model groups received an equal volume of physiological saline. After the intervention, the 7-day survival rate of each group was recorded, and spleen samples were collected 72 h post-intervention, and the spleen index was calculated. Terminal deoxynucleotidyl transferase deoxyuridine triphosphate(dUTP) nick end labeling(TUNEL) staining was used to detect apoptosis in spleen cells. Enzyme-linked immunosorbent assay(ELISA) was performed to measure the levels of interleukin(IL)-4 and IL-10 in the serum. Transcriptomics and metabolomics were used to screen for differentially expressed genes(DEGs) and differential metabolites in the spleen, followed by bioinformatics analysis to identify key targets. Real-time quantitative polymerase chain reaction(Real-time PCR), flow cytometry, and multiplex immunofluorescence were used to verify the expressions of key genes and proteins. ResultsThe high-dose YHJF group significantly improved the 7-day survival rate of septic mice(P0.05). Compared with the sham-operated group, the model group showed a significant increase in apoptosis of spleen cells and a decrease in the spleen index at 72 h post-modeling, with markedly elevated peripheral serum IL-4 and IL-10 levels(P0.01). Compared with the model group, the high-dose YHJF group showed a reduction in apoptosis of spleen cells, an increase in the spleen index, and a significant decrease in peripheral serum IL-4 and IL-10 levels(P0.05). Spleen transcriptomics identified 255 DEGs between groups, potentially serving as intervention targets for YHJF. Gene Ontology(GO) enrichment analysis revealed that DEGs were mainly involved in biological processes such as natural killer(NK) cell-mediated positive immune regulation, cell killing, cytokine production, positive regulation of innate immune cells, and interferon production. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis showed that DEGs were mainly involved in cytokine-cytokine receptor interactions, viral protein interactions with cytokines and cytokine receptors, chemokine signaling pathway, and nuclear transcription factor-κB(NF-κB) signaling pathway. Protein-protein interaction(PPI) network analysis identified CD160, granzyme B(GZMB), and chemokine ligand 4(CCL4) as key targets for YHJF in treating sepsis. Metabolomics identified 46 differential metabolites that were significantly reversed by YHJF intervention, and combined transcriptomics and metabolomics analysis identified 17 differential metabolites closely related to CD160. Pathway enrichment revealed that these metabolites were mainly involved in glycerophospholipid metabolism, arachidonic acid metabolism, glycosylphosphatidylinositol(GPI) anchor biosynthesis, linoleic acid metabolism, and α-linolenic acid metabolism pathways. Verification results showed that, compared with the sham-operated group, the model group exhibited significantly elevated CD160 mRNA expression level in the spleen, along with markedly decreased CCL4 and GZMB mRNA expression, and had a significant increase in CD160 expression on the surface of natural killer T(NKT) cells in the spleen(P0.01). Compared with the model group, the high-dose YHJF group had a significant decrease in CD160 mRNA expression in the spleen, a significant increase in CCL4 and GZMB mRNA expressions. Further flow cytometry and immunofluorescence revealed that compared with the sham-operated group, CD160 expression on the surface of splenic NKT cells in the model group was significantly increased(P0.01), while high-dose YHJF intervention significantly reduced CD160 expression(P0.01). ConclusionYHJF may alleviate NKT cell exhaustion in sepsis by downregulating the expression of the negative co-stimulatory molecule CD160, and this regulatory effect is closely related to fatty acid metabolism pathways. This study provides new insights and targets for further exploration of strengthening vital Qi and detoxifying strategy to improve immune cell exhaustion in acute deficiency syndrome of sepsis.

Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity, and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity, this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine (TCM) herbs that strengthen the spleen, regulate qi, and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation, promoting water-damp metabolism, and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness, internal accumulation of phlegm dampness" and immune dysregulation in obesity, this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Attention deficit hyperactivity disorder (ADHD) is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind, which leads to disharmony between the body and spirit, resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids, calming ministerial fire, and extinguishing endogenous wind (内风). The method of nourishing yin fluids is applied throughout the entire treatment process, commonly using ingredients such as Shudihuang (Rehmanniae Radix Praeparata), Shanzhuyu (Corni Fructus), Gouqizi (Lycii Fructus), Wuweizi (Schisandrae Chinensis Fructus), and Tusizi (Cuscutae Semen). These are combined with approaches to harmonize the zang-fu organs, primarily including extinguishing liver wind, clearing heart fire, nourishing kidney water, and strengthening spleen earth, thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally, emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

Autoimmune liver diseases (AILD) are a group of chronic liver diseases caused by abnormal activation of the immune system, mainly including autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, IgG4-related sclerosing cholangitis, and overlap syndrome. Clinical studies have shown that patients with AILD are often comorbid with thyroid diseases, especially autoimmune thyroid diseases (AITD), such as Graves’ disease and Hashimoto’s thyroiditis. This article systematically reviews the epidemiological association, potential shared pathogenesis, and overlapping features between AILD and thyroid diseases. A deeper understanding of the immunological links between AILD and AITD may provide a theoretical basis for precision medicine and future research.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors (DTIs) in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital (the Affiliated Hospital of UESTC), a multidisciplinary working group was established. Through literature review and the Delphi method, clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework; systematic searches were conducted in CNKI, Medline, Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment,Development and Evaluation (GRADE) approach, and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations (each with an expert consensus rate exceeding 90%) on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection, dosing ranges, key monitoring points, and safety management strategies for parenteral DTIs in various scenarios, including the perioperative period of ventricular assist device implantation, the perioperative period of cardiac surgery, perioperative patients with lower-extremity atherosclerotic disease, the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome, the perioperative period of carotid artery stenting in patients with carotid stenosis, the perioperative period of patients with right heart thrombosis, and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition, warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus, which is formulated based on the best available evidence, provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

OBJECTIVE To systematically evaluate the quality of the Heat-clearing and symptom-relieving formula and screen potential marker components that influence the quality of the formula. METHODS The contents of 11 components (calycosin-7- O - β -D-glucoside, ononin, hyperoside, isoquercitrin, baicalin, baicalein, cryptotanshinone, tanshinone Ⅱ A , tanshinone Ⅰ, senkyunolide A, ferulic acid) in the Heat-clearing and symptom-relieving formula were determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Using the contents of the aforementioned components as variables, cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were conducted using OriginPro 2024 software and SIMCA 14.1 software; marker components affecting the quality of the Heat-clearing and symptom-relieving formula were then screened based on the criteria of variable importance in the projection (VIP) value>1 and P <0.05. The comprehensive evaluation of 20 batches of samples was carried out using the entropy weight-technique for order preference by similarity to ideal solution(TOPSIS) and grey correlation analysis (GCA) methods. RESULTS The contents of the above 11 components were 7.993-72.866, 4.542-31.228, 727.666-1 901.884, 496.846-1 293.279, 1 995.501-6 779.150, 54.500-241.280, 150.302-304.339, 79.698-189.206, 257.118-682.418, 5.498-21.687, 7.524-26.935 μg/g. CA, PCA and OPLS-DA results showed that 20 batches of samples were grouped into 2 categories. Q1, Q3, Q4, Q7-Q9, Q12, Q15, Q16 were grouped into one category, and the rest were grouped into another category; VIP values of ferulic acid, tanshinone Ⅱ A , baicalin, cryptotanshinone, calycosin-7- O - β -D-glucoside and ononin were all greater than 1 ( P <0.05). Both the entropy weight-TOPSIS and GCA methods showed that the samples ranked in the top 11 according to the euclidean distance and relative correlation degree were Q2, Q5, Q6, Q10, Q11, Q13, Q14, Q17-Q20. CONCLUSIONS The established HPLC-MS/MS method is rapid, accurate and highly sens itive. Combined with chemical pattern recognition analysis, entropy weight-TOPSIS and GCA methods, this method can be used to evaluate the quality of the Heat-clearing and symptom-relieving formula. Ferulic acid, tanshinone Ⅱ A , baicalin, cryptotanshinone, calycosin-7- O - β -D-glucoside and ononin may be the marker components that affect the quality of this formula. The overall quality of 11 batches of the Heat-clearing and symptom-relieving formula, including Q17, is relatively superior.
