ObjectiveTo systematically identify the main chemical components of Linggui Zhugan granules （LGZGG）， and to explore the pharmacodynamic substance basis for the treatment of metabolic dysfunction-associated steatohepatitis （MASH）. MethodsThe chemical components of LGZGG were systematically analyzed by ultra-performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry （UPLC-Q-TOF-MS/MS）. The protein-protein interaction （PPI） network and "compound prescription-disease-component-target" network were constructed by network target analysis to predict the potential pharmacodynamic substances and core targets of LGZGG in the treatment of MASH. The potential pharmacodynamic substances were enriched by macroporous adsorption resin， and the chemical composition of the LGZGG-50% ethanol elution fraction （LGZGG-50） was analyzed by UPLC-Q-TOF-MS/MS. The mouse model of MASH was established by feeding a high-fat， high-cholesterol， and high-fructose diet for 12 weeks. Mice were randomly allocated into normal， model， positive drug （MGL-3196， 1 mg·kg^-1）， LGZGG （crude drug， 34 g·kg^-1·d^-1）， LGZGG-50 （crude drug， 34 g·kg^-1·d^-1） groups. The levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） in the serum were measured， and the pathological changes in the liver tissue were observed by hematoxylin-eosin （HE） and Sirius red staining. The in vivo efficacy of LGZGG and LGZGG-50 in the treatment of MASH was evaluated on the basis of the findings. The expression levels of adenosine monophosphate-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， silent information regulator 2-related enzyme 1 （SIRT1）， peroxisome proliferator-activated receptor α （PPARα）， and carnitine palmitoyltransferase 1A （CPT1A） in the liver tissue were determined by Western blot to verify the regulatory effects of core targets. ResultsA total of 83 chemical components were identified from LGZGG， including 20 flavonoids， 13 terpenoids， 17 organic acids， 7 amino acids， 11 glycosides， 3 nucleosides， 3 aromatics， 3 alkaloids， 2 phenylpropanoids， 2 sugars， 1 nucleic acid， and 1 steroid. A total of 134 common targets were obtained by network target analysis. The core targets included SIRT1， PPARα， nuclear factor-kappa B subunit 1 （NF-κB1）， and interleukin-6 （IL-6）. Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis revealed that the targets were mainly enriched in the AMPK， PPAR and other signaling pathways. The topological analysis of the "compound prescription-disease-component-target" network showed that the potential pharmacodynamic substances of LGZGG against MASH were flavonoids and terpenoids. The relative content of flavonoids and terpenes in LGZGG-50 were 74.00% and 62.41% in positive and negative ion modes， respectively， indicating that LGZGG-50 effectively enriched total flavonoids and total terpenoids. The results of in vivo efficacy showed that compared with the model group， LGZGG and LGZGG-50 reducef the body weight， liver weight， serum TG， GLU， and ALT levels of MASH mice （P<0.05，P<0.01）， and LGZGG additionally increased the HDL-C level （P<0.01）. Both groups alleviated the pathological damage in the liver tissue. The results of Western blot showed that compared with the model group， the protein levels of p-AMPK/AMPK， SIRT1， PPARα， and CPT1A were up-regulated in the LGZGG group （P<0.05，P<0.01）， and those of p-AMPK/AMPK and CPT1A were up-regulated in the LGZGG-50 group （P<0.01）. ConclusionLGZGG ameliorates MASH， with the main pharmacodynamic substances being flavonoids and terpenoids. The mechanism may be related to the regulation of AMPK/SIRT1/PPARα signaling pathway， improvement of lipid metabolism， and alleviation of pathological damage in the liver tissue.

[Objective] : To predict the potential targets of Qingfu Juanbi Decoction (青附蠲痹汤, QFJBD) in treating rheumatoid arthritis (RA) using an improved Transformer model and investigate the network pharmacological mechanisms underlying QFJBD’s therapeutic effects on RA. Methods: First, a traditional Chinese medicine herb-target interaction (TCMHTI) model was constructed to predict herb-target interactions based on Transformer improvement. The performance of the TCMHTI model was evaluated against baseline models using three metrics: area under the receiver operating characteristic curve (AUC), precision-recall curve (PRC), and accuracy. Subsequently, a protein-protein interaction (PPI) network was built based on the predicted targets, with core targets identified as the top nine nodes ranked by degree values. Gene Ontology (GO) functional and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using the targets predicted by TCMHTI and the targets identified through network pharmacology method for comparison. Then, the results were compared. Finally, the core targets predicted by TCMHTI were validated through molecular docking and literature review. Results: The TCMHTI model achieved an AUC of 0.883, PRC of 0.849, and accuracy of 0.818, predicting 49 potential targets for QFJBD in RA treatment. Nine core targets were identified: tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-10, IL-17A, cluster of differentiation 40 (CD40), cytotoxic T-lymphocyte-associated protein 4 (CTLA4), IL-4, and signal transducer and activator of transcription 3 (STAT3). The enrichment analysis demonstrated that the TCMHTI model predicted 49 targets and enriched more pathways directly associated with RA, whereas classical network pharmacology identified 64 targets but enriched pathways showing weaker relevance to RA. Molecular docking demonstrated that the active molecules in QFJBD exhibit favorable binding energy with RA targets, while literature research further revealed that QFJBD can treat RA through 9 core targets. Conclusion The TCMHTI model demonstrated greater accuracy than traditional network pharmacology methods, suggesting QFJBD exerts therapeutic effects on RA by regulating targets like TNF-α, IL-1β, and IL-6, as well as multiple signaling pathways. This study provides a novel framework for bridging traditional herbal knowledge with precision medicine, offering actionable insights for developing targeted TCM therapies against diseases.

Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.

ObjectiveTo investigate the effect of alcohol extract of Oroxylum indicum （MHD-80） on reducing uric acid （UA） and protecting the kidney in the hyperuricemia （HUA） model in vivo. MethodPotassium oxazine （350 mg·kg^-1） and adenine （80 mg·kg^-1） were used to construct an HUA model of mice in vivo to evaluate the mechanism related to UA reduction and the protective effect of renal function of MHD-80. Seventy male ICR mice were randomly divided into seven groups， including the normal group， model group， allopurinol group （5 mg·kg^-1）， febusotan group （5 mg·kg^-1）， and MHD-80 low-， medium-， and high-dose groups （3， 6， 12 mg·kg^-1）， with 10 in each group. Except for the normal group， the other groups were given intragastric administration of potassium oxazine and adenine for 14 consecutive days to establish the HUA model. On the 8^th to 14^th day after modeling， each group was given corresponding drugs by intragastric administration， once a day. 1 h after the last administration， blood was collected from the eyeballs， and kidney and liver tissues of mice were collected. Serum levels of UA， urea nitrogen （BUN）， and creatinine （Cr） and liver activity of xanthine oxidase （XOD） were determined by enzyme colorimetry. Serum contents of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） were determined by enzyme-linked immunosorbent assay （ELISA）. Hematoxilin-eosin （HE） staining was used to observe the pathological changes in kidney tissues. The protein expression levels of ATP-binding box transporter G2 （ABCG2） and glucose-facilitating transporter 9 （GLUT9） in kidney tissues were detected by Western blot. ResultIn vivo experiment shows that compared with the normal group， the serum levels of UA， Cr， BUN， inflammatory factors TNF-α， IL-1β， and liver XOD activity in the serum of mice in the model group were significantly increased （P<0.05， P<0.01）， and the expression of GLUT9 in kidney tissues was significantly up-regulated （P<0.05）. ABCG2 protein expression was significantly down-regulated （P<0.05）， and renal injury was obvious. Compared with the model group， the levels of UA， BUN， Cr， TNF-α， IL-1β， and liver XOD activity in the serum of mice in the high-dose group of MHD-80 were decreased to different degrees （P<0.05， P<0.01）， GLUT9 protein expression was significantly down-regulated （P<0.01）， ABCG2 protein expression was significantly up-regulated （P<0.05） in the high-dose group of MHD-80， and the degree of renal injury was reduced. ConclusionMHD-80 has certain uric acid reduction， anti-inflammatory， and anti-renal injury effects， which are related to inhibiting XOD activity and regulating the expression of ABCG2 and GLUT9 uric acid transporter.

Objective    To investigate the predictive value of right atrial myocardial fibrosis in the prognosis of isolated tricuspid regurgitation surgery after left heart valve surgery. Methods    The patients who underwent tricuspid valvuloplasty by the same operator in Guangdong Provincial People's Hospital from April 2016 to August 2021 due to long-term isolated severe tricuspid regurgitation after left heart valve surgery were included in the study. According to the degree of right atrial myocardial fibrosis, the patients were divided into three groups: a mild group, a moderate group, and a severe group. The clinical data of these patients were compared and analyzed. Results    A total of 75 patients were enrolled, including 16 males and 59 females with an average age of 57.0±8.4 years. There were 30 patients in the mild group, 29 patients in the moderate group and 16 patients in the severe group. In terms of the preoperative data, there were statistical differences in cardiac function grade, right atrial diameter, tricuspid incompetence area among the three groups (P<0.05). In terms of the postoperative data, there were statistical differences among the three groups in the cardiopulmonary bypass time, mechanical ventilation time, ICU monitoring time, complication rate and mortality (P<0.05). Further pairwise comparison showed that, compared with the mild group, the severe group had longer mechanical ventilation time (P=0.024), longer ICU monitoring time (P=0.003) and higher incidence of postoperative complications (P=0.024), while the moderate group had no statistical difference in all aspects (P>0.05); compared with the moderate group, the severe group had longer ICU monitoring time (P=0.021) and higher incidence of complications (P=0.006). Conclusion    The early outcome of tricuspid valvuloplasty in patients with isolated tricuspid regurgitation after left heart valve surgery with severe right atrial myocardial fibrosis is worse than that in the patients with mild and moderate fibrosis, suggesting that the degree of myocardial fibrosis in the right atrium can be a predictor of the effect of tricuspid regurgitation surgery and a judgement indicator of the surgery timing.

Objective: To elucidate the anti-inflammatory mechanism of Reduning Injection (RDN) by analyzing the potential biomarkers and metabolic pathways of the carrageenan-induced inflammatory model from the overall metabolic level. Methods: Rat inflammatory model was established by carrageenan. UPLC-Q-TOF/MS was used to detect and analyze changes of endogenous metabolites in the serum and urine of carrageenan-induced inflammatory rats. Combined with multivariate analysis and databases analysis, inflammatory-related potential biomarkers were screened and identified to analyze possible metabolic pathways. The reliability and biological significance of these biomarkers was verified by metabolic network analysis and correlation analysis with pharmacodynamic indicators. Results: A total of 16 potential biomarkers were screened and identified by multivariate analysis and metabolite databases, among which 13 species could be adjusted by RDN. The metabolism pathway analysis revealed that histidine metabolism, sphingolipid metabolism, and tyrosine metabolism were greatly disturbed. Their biomarkers involved urocanic acid, sphingosine, and norepinephrine, all of which showed a callback trend after RDN treatment. The three biomarkers had a certain correlation with some known inflammatory-related small molecules (histamine, arachidonic acid, Leukotriene B4, and PGE
