ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-electrostatic field orbital trap-linear ion-trap mass spectrometry（UPLC-Orbitrap Fusion Lumos Tribrid-MS）， the plasma concentration of ziyuglycoside Ⅰ was determined at different time points after oral administration， and its pharmacokinetic characteristics in normal rats and rats with acute kidney injury were compared. MethodsRats were randomly divided into normal group and model group， the model group received intraperitoneal cisplatin（10 mg·kg^-1） to establish the acute kidney injury model， the normal group was given the same volume of saline. After successful modeling， rats in the normal and model groups were randomly divided into the normal low， medium and high dose groups（2.5， 5， 7.5 mg·kg^-1） and the model low， medium and high dose groups（2.5， 5， 7.5 mg·kg^-1）， 6 rats in each group， and the plasma was collected at different time points after receiving the corresponding dose of ziyuglycoside Ⅰ. Then， the concentration of ziyuglycoside Ⅰ in rat plasma was determined by UPLC-Orbitrap Fusion Lumos Tribrid-MS， and the drug-time curve was poltted. The pharmacokinetic parameters were calculated by Kinetica 5.1 software， and the differences in pharmacokinetic parameters between different administration groups were compared by independent sample t-test with SPSS 22.0. ResultsThe pharmacokinetic results showed that after receiving the different doses of ziyuglycoside Ⅰ， its concentration increased first and then decreased， and all of them reached the maximum plasma concentration at about 0.5 h. The area under the curve（AUC_0-t） and mean retention time（MRT_0-t） of normal and model rats increased with the increased dose， and the clearance（CL） decreased with the increasing dose. Compared with the normal group， the AUC_0-t was significantly increased（P<0.01）， peak concentration（C_max） and CL decreased in model rats at different doses， indicating that the physiological state of the rats could affect the absorption and elimination of ziyuglycoside Ⅰ in vivo. ConclusionThe pharmacokinetic characteristics of ziyuglycoside Ⅰ are quite different in normal rats and acute kidney injury model rats， which may be due to the change of the body environment in the pathological state， then lead to changes in absorption and metabolic processes.

Viral pneumonia is an infectious disease caused by virus invading the lung parenchyma and interstitial tissue and causing lung inflammation， with the incidence rising year by year. Traditional Chinese medicine （TCM） can treat viral pneumonia in a multi-component， multi-target， and holistic manner by targeting the core pathogenesis of pneumonia caused by different respiratory viruses， demonstrating minimal side effects and significant advantages. According to the theory of healthy Qi and pathogenic Qi in TCM， the struggle between healthy Qi and pathogenic Qi and the imbalance between immunity and inflammation run through the entire process of viral pneumonia， and the immunity-inflammation status at different stages of the disease reflects different relationships between healthy Qi and pathogenic Qi. Immune dysfunction leads to the deficiency of healthy Qi， causing viral infections. The struggle between healthy Qi and pathogenic Qi causes immunity-inflammation imbalance， leading to the onset of viral pneumonia. Inflammatory damage causes persistent accumulation of phlegm and stasis， leading to the progression of viral pneumonia. The cytokine storm causes immunodepletion， leading to the excess of pathogenic Qi and diminution of healthy Qi and the deterioration of viral pneumonia. After the recovery from viral pneumonia， there is a long-term imbalance between immunity and micro-inflammation， which results in healthy Qi deficiency and pathogenic Qi lingering. Healthy Qi deficiency and pathogenic Qi excess act as common core causes of pneumonia caused by different respiratory viruses. Clinical treatment should emphasize both replenishing healthy Qi and eliminating pathogenic Qi， helping to restore the balance between healthy Qi and pathogenic Qi as well as between immunity and inflammation， thus promoting the recovery of patients from viral pneumonia. According to the TCM theory of healthy Qi and pathogenic Qi， this article summarizes the immunity-inflammation mechanisms at different stages of viral pneumonia， and explores the application of the method of replenishing healthy Qi and eliminating pathogenic Qi in viral pneumonia. The aim is to probe into the scientific connotation of the TCM theory of healthy Qi and pathogenic Qi in viral pneumonia and provide ideas for the clinical application of the method of replenishing healthy Qi and eliminating pathogenic Qi to assist in the treatment of viral pneumonia.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Background Prenatal exposure to chlorinated polyfluorinated ether sulfonic acid (Cl-PFESA, commercially known as F-53B) during pregnancy has been associated with fetal growth restriction and adverse birth outcomes. These effects may be mediated by structural and functional impairments of the placenta, potentially resulting from disrupted placental angiogenesis. However, the underlying mechanisms remain unclear. Objective To explore the impact of prenatal F-53B exposure on fetal development, placental pathology, and the expression of genes involved in angiogenesis by establishing an F-53B exposure animal model. Methods A total of 48 sexually mature female SD rats aged 8 weeks were selected, along with 24 proven male breeders. The rats were acclimatized for one week before mating. Pregnant rats were assigned to four groups: control (0 mg·kg⁻¹), low-dose (0.1 mg·kg⁻¹), medium-dose (1 mg·kg⁻¹), and high-dose (5 mg·kg⁻¹). Half of the pregnant rats in each group were administered the test substance by oral gavage once daily from gestational day (GD) 5.5 to GD17.5. The fetuses and placentas were dissected and weighed, and placental efficiency was calculated as the ratio of fetal weight to placental weight, reflecting the placenta’s capacity to supply nutrients to the fetus. Placental histopathological alterations were assessed after hematoxylin and eosin (HE) staining. Quantitative real-time polymerase chain reaction (qPCR) was conducted to assess the mRNA expression levels of angiogenesis-related genes, including hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor A (VEGFA) and its receptor (VEGFR2), as well as downstream genes in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway. To evaluate the potential impact of prenatal F-53B exposure on birth outcomes, including birth weight and gestational age, the remaining half of the pregnant rats in each group were continuously exposed to the test substance until delivery. Results F-53B exposure significantly reduced fetal weight across all exposure groups (P<0.05) and markedly increased the incidence of intrauterine growth restriction (P<0.01). Although placental weights did not differ significantly among groups, placental efficiency was significantly decreased in the high-dose group (P<0.05). The histological analysis after HE staining revealed disorganized trophoblast cell structure and a significant reduction in labyrinthine blood sinus area in the medium- and high-dose groups. The qPCR analysis showed that HIF-1α expression was significantly upregulated in the low-dose group (P<0.001), while VEGFA (P<0.01), PI3K (P<0.001), and AKT (P<0.05) expression levels were significantly downregulated in the medium- and high-dose groups. Conclusion Maternal exposure to F-53B during pregnancy may impair placental angiogenesis via VEGFA and its downstream PI3K/AKT signaling pathway, leading to placental pathological damage and increasing the risk of intrauterine growth restriction and reduced birth weight in fetuses.

Diabetes mellitus(DM)is a disease syndrome characterized by chronic hyperglycaemia.A long-term high-glucose environment leads to reactive oxygen species(ROS)production and nuclear DNA damage.Human umbilical cord mesenchymal stem cell(HUcMSC)infusion induces significant antidiabetic effects in type 2 diabetes mellitus(T2DM)rats.Insulin-like growth factor 1(IGF1)receptor(IGF1R)is important in promoting glucose metabolism in diabetes;however,the mechanism by which HUcMSC can treat diabetes through IGF1R and DNA damage repair remains unclear.In this study,a DM rat model was induced with high-fat diet feeding and streptozotocin(STZ)administration and rats were infused four times with HUcMSC.Blood glucose,interleukin-6(IL-6),IL-10,glomerular basement membrane,and renal function were examined.Proteins that interacted with IGF1R were determined through coimmunoprecipitation assays.The expression of IGF1R,phosphorylated checkpoint kinase 2(p-CHK2),and phosphorylated protein 53(p-p53)was examined using immunohistochemistry(IHC)and western blot analysis.Enzyme-linked immunosorbent assay(ELISA)was used to determine the serum levels of 8-hydroxydeoxyguanosine(8-OHdG).Flow cytometry experiments were used to detect the surface markers of HUcMSC.The identification of the morphology and phenotype of HUcMSC was performed by way of oil red"O"staining and Alizarin red staining.DM rats exhibited abnormal blood glucose and IL-6/10 levels and renal function changes in the glomerular basement membrane,increased the expression of IGF1 and IGF1R.IGF1R interacted with CHK2,and the expression of p-CHK2 was significantly decreased in IGF1R-knockdown cells.When cisplatin was used to induce DNA damage,the expression of p-CHK2 was higher than that in the IGF1R-knockdown group without cisplatin treatment.HUcMSC infusion ameliorated abnormalities and preserved kidney structure and function in DM rats.The expression of IGF1,IGF1R,p-CHK2,and p-p53,and the level of 8-OHdG in the DM group increased significantly compared with those in the control group,and decreased after HUcMSC treatment.Our results suggested that IGF1R could interact with CHK2 and mediate DNA damage.HUcMSC infusion protected against kidney injury in DM rats.The underlying mechanisms may include HUcMSC-mediated enhancement of diabetes treatment via the IGF1R-CHK2-p53 signalling pathway.

Objective To explore the mechanism of dendrobine in the treatment of diabetic kidney disease(DKD)by intervening immunity using network pharmacology,bioinformatics and Western blot.Methods The targets of dendrobine were screened by Pharmmaper,Superpred and other databases.The disease targets of DKD were screened from GeneCards,OMIM and other databases.The immune-related targets were searched in Immport,In-nateDB and other databases.The intersection of the above three was obtained via Venn diagram.The PPI map of intersection targets was constructed by STRING software combined with Cytoscape software,and the core targets in the interaction network were mined by CytoHubba plug-in.The data set GSE142025 was obtained from GEO,and immune infiltration and WGCNA analysis were performed using the R language CIBERSORT package.GSE1009,GSE30122 and GSE142025 were used for gene differential expression analysis and ROC verification.The correla-tion between core targets and immune cell phenotype was analyzed.Molecular docking and molecular dynamics sim-ulation analysis were used to test the binding force of dendrobine to key targets.Western blot was used to detect the expression of HSP90AA1 in HK-2 cells.Results A total of 128 intersecting genes,including HSP90AA1,LCK and EGFR,were obtained,and the core targets involved HSP90AA1,LCK and STAT3;molecular docking and molecular dynamics simulation analyses showed that the protein of HSP90AA1 could bind well with dendrobine.Western blot experiments showed that compared with the control group,HSP90AA1 was significantly down-regula-ted in the high glucose group.Compared with the high glucose group,HSP90AA1 was significantly up-regulated in the dendrobine group.Conclusion Dendrobine can intervene in diabetic kidney disease by regulating the expres-sion of HSP90AA1.
