Diabetic cardiomyopathy (DCM) is one of the most common complications of diabetes mellitus and is a major threat to global health. As a key mechanism in the occurrence and progression of DCM, the inflammatory response persists throughout the entire course of the DCM. The Gaozhuo theory suggests that the basic pathogenesis of inflammatory injury in DCM is the Qi deficiency of spleen and kidney and Gaozhuo invasion, and divides the pathological process into three phases: Gaozhuo invasion, turbid heat damage to the channels, and turbid blood stasis and heat junction. Among them, the Qi deficiency of spleen and kidney and the endogenous formation of Gaozhuo represent the process of inflammatory factor formation induced by glucose metabolism disorders. Turbid heat damage to the channels refers to the process of myocardial inflammatory injury mediated by inflammatory factors, and turbid blood stasis and heat junction are the process of myocardial injury developing toward myocardial fibrosis and ventricular remodeling. As the disease continues to progress, it eventually develops into a depletion of the heart Yang, leading to the ultimate regression of heart failure. According to the theory of Gaozhuo, traditional Chinese medicine (TCM) should regulate inflammatory injury in DCM by strengthening the spleen and tonifying the kidney to address the root cause, and resolving dampness and lowering turbidity to treat the symptoms. If the turbidity has been stored for a long time and turns into heat, strengthening the spleen and tonifying the kidney, and clearing heat and resolving turbidity should be the therapy. If the turbidity, stasis, and heat are knotted in the heart and collaterals, strengthening the spleen and tonifying the kidney, and resolving stasis and lowering turbidity should be the therapy. TCM compounds and monomers can regulate the inflammatory response in DCM. TCM compounds can be divided into the categories for benefiting Qi to resolve turbidity, benefiting Qi and clearing heat to resolve turbidity, and benefiting Qi and activating blood to reduce turbidity. The compounds can inhibit upstream signals of inflammation and expression of inflammatory factors, improve the inflammatory damage to myocardium and blood vessels, myocardial fibrosis, and cardiac systole and diastole, and thus slow down the onset and progression of DCM.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common complications of type 2 diabetes mellitus (T2DM), and hepatic stellate cell (HSC) activation is the key link in the progression of NAFLD to liver fibrosis. According to the theory of "Gaozhuo", spleen deficiency and Qi stagnation, along with Gaozhuo invasion, are the causes of NAFLD progression to liver fibrosis, which reveals the pathogenesis essence of HSC activation in traditional Chinese medicine (TCM). Among them, spleen deficiency and Qi stagnation are the root causes of the endogenous formation of Gaozhuo. Spleen deficiency indicates the insulin sensitivity decrease and glucose metabolism disorders, and Qi stagnation means the dysregulation of hepatic glucose and lipid metabolism, which creates the preconditions for HSC activation. Gaozhuo invasion is the direct cause of HSC activation, including three stages: Internal retention of Gaozhuo, turbidity and stasis stagnation, and toxic stasis and consolidation. Internal retention of Gaozhuo refers to the abnormal metabolism and deposition of hepatic lipids, as well as the microcirculatory disorders. Turbidity and stasis stagnation is the process by which lipotoxicity stimulates the transformation of HSC into myofibroblast (MFB), and toxic stasis and consolidation represent the secretion of a large amount of extracellular matrix (ECM) by MFB to promote the fibrosis. According to the theory of Gaozhuo and the activation process of HSC, syndromes for T2DM combined with NAFLD can be classified into spleen deficiency and Qi stagnation with internal retention of Gaozhuo, spleen Qi deficiency with turbidity and stasis stagnation, and spleen Qi deficiency with toxic stasis and consolidation. Clinically, the treatment principle is to strengthen the spleen and promote Qi, resolve turbidity, and eliminate blood stasis. Both TCM compounds and monomers can effectively inhibit the HSC activation. TCM compounds can be classified into categories for regulating spleen and harmonizing liver, resolving turbidity and removing stasis, and detoxifying and removing stasis. They mainly work by improving lipid metabolism, reducing lipid accumulation in the liver, alleviating inflammatory and oxidative stress responses, inhibiting the activation and proliferation of HSC, and reducing ECM deposition, thereby delaying the progression of liver fibrosis.

ObjectiveTo explore the molecular mechanisms by which serum containing Gegen Qinlian Tang (GQT) inhibits glycolysis and enhances chemotherapy sensitivity in 5-fluorouracil (5-FU)-resistant colorectal cancer (CRC) cells based on the cyclin-dependent kinase 16 (CDK16)/MYC proto-oncogene (MYC) pathway. MethodsHCT-116/5-FU cells were treated with different concentrations (5%, 10%, 20%, 30%) of GQT-containing serum. Cell viability and 5-FU sensitivity were assessed using the cell counting kit-8 (CCK-8) assay, and the experimental concentrations of 5-FU and GQT for subsequent experiments were determined. Cell proliferation and apoptosis under individual 5-FU, GQT, and combined 5-FU + GQT treatments were evaluated using 5-ethynyl-2′-deoxyuridine (EDU) staining and annexin V-FITC/PI double staining, respectively. Glucose consumption, adenosine triphosphate (ATP) production, and lactate levels were measured by colorimetric assays. Expression levels of glycolysis-related proteins, CDK16, MYC, and phosphorylated MYC were detected by Western blot. Co-immunoprecipitation (CoIP) was used to examine the protein interaction between CDK16 and MYC, and cycloheximide (CHX) treatment was applied to assess the effect of CDK16 overexpression on MYC protein stability. ResultsCCK-8 assays showed that 2.5 mg·L-1 5-FU significantly inhibited HCT-116 cell viability in a dose-dependent manner. In HCT-116/5-FU cells, significant inhibition was observed only at 5 mg·L-1 5-FU (P<0.05), which was used for model establishment. Compared with 5-FU alone, addition of 5% GQT-containing serum significantly suppressed HCT-116/5-FU cell viability (P<0.05), with stronger inhibition at higher serum concentrations. Thus, 5% GQT-containing serum was used in subsequent experiments. Compared with the control group, 5-FU, GQT, and 5-FU + GQT treatments all significantly reduced cell proliferation (P<0.05) and increased apoptosis (P<0.01). The 5-FU + GQT combination showed superior inhibition of proliferation compared with 5-FU or GQT alone (P<0.01), accompanied by more pronounced reductions in glucose consumption, ATP production, and lactate generation (P<0.01). Additionally, compared with control, 5-FU, and GQT groups, the 5-FU + GQT group exhibited stronger suppression of MYC and its phosphorylated forms (P<0.01) and greater inhibition of glycolytic enzymes, including hexokinase 2 (HK2), 3-phosphoinositide-dependent protein kinase 1 (PDK1), lactate dehydrogenase A (LDHA), and pyruvate kinase M2 (PKM2) (P<0.01). CDK16, MYC, and MYC phosphorylation expression levels were significantly downregulated in the 5-FU + GQT group compared with the 5-FU group (all P<0.01). MYC protein stability decreased in a time-dependent manner in the 5-FU + GQT group (P<0.05), which was rescued by CDK16 overexpression (P<0.05). ConclusionGQT significantly enhances the sensitivity of HCT-116/5-FU cells to 5-FU, potentially by inhibiting CDK16 and thereby reducing MYC-mediated glycolysis.

Objective: To investigate the current knowledge status of transfusion medicine among pediatricians/postgraduates and the reliability of large language models (LLMs) for assisted learning, and to assess changes in pediatricians' transfusion medicine knowledge before and after the implementation of the "Pediatric Transfusion Guideline" (hereafter referred to as the "Guideline"). Methods: In January 2022 (prior to the implementation of the "Guideline"), a questionnaire was developed based on the "Guideline" content and distributed to pediatricians. Subsequently, in July 2025 (after the implementation of the "Guideline"), the "Pediatric Transfusion Medicine Knowledge Questionnaire" was designed based on the content of the January 2022 questionnaire. This questionnaire survey was conducted on pediatricians/postgraduates and LLMs. We analyzed the level of transfusion medicine knowledge among pediatricians/postgraduates and the reliability of LLMs for assisted learning, and compared the accuracy of pediatricians' responses before and after "Guideline" implementation. Results: The survey results after the implementation of the "Guidelines" revealed that pediatricians/postgraduates achieved response accuracy rates exceeding 80% on the topic of "Patient Blood Management". However, response accuracy rates were below 30% for topics including "Types and Indications of Blood Components/Products" and "E-valuation of Transfusion Efficacy". The pediatricians' accuracy rates for related questions before and after the implementation of the "Guidelines" were 14.7%-68.9% and 3%-38%, respectively, and the comparison of accuracy rates for each question showed significant differences (P<0.001). The accuracy rates of the LLMs on the questionnaire were all below 90%. Among them, Doubao (81.1%) and Kimi (86.4%) achieved relatively higher accuracy rates, while Tencent Yuanbao (Hunyuan) had the lowest accuracy rate at only 59.5%. Conclusion: The implementation of the "Guideline" may have improved pediatricians' knowledge level of pediatric transfusion medicine. However, their knowledge level of pediatric transfusion remains low, and LLMs cannot yet provide absolutely reliable guidance. Systematic training in pediatric transfusion medicine is urgently needed.

Objective To analyze the influenza-like illness (ILI) data in Ordos City from 2017 to 2023 and conduct nucleic acid detection of the virus to understand the local influenza epidemic situation, and to provide a reliable basis for influenza prevention and control in the city. Methods Real-time quantitative polymerase chain reaction (qPCR) was used to identify virus subtypes in ILI throat swab samples. Comparisons of positive rates were conducted using the chi-square test, with a significance level of α=0.05. Results From 2017 to 2023, a total of 3,283,434 outpatient and emergency visits were recorded at the Ordos City Central Hospital, including 74,159 ILI cases, with an ILI proportion of 2.26%. The majority of ILI cases (74.43%) occurred in children aged 0~14 years old. The overall positive rate of influenza virus nucleic acid detection was 10.87%, with the highest proportion being subtype A (seasonal H3) at 43.03%. The highest detection rate was observed in the 5~14 years age group, with statistically significant differences in positive rates across age groups (χ2=155.638, P<0.001). Influenza peaks occurred mainly from November to March of the following year. From January to April, three types of influenza were prevalent alternately or mixed, while from October to December, subtype A (seasonal H3) predominated. Positive rates varied significantly across months (χ2=250.923, P<0.001). The temporal trends of ILI proportions and PCR-positive rates were consistent. Conclusion Influenza in Ordos City exhibits distinct seasonal and age distribution characteristics, with alternating or mixed circulation of three virus types. Continued efforts are needed to strengthen influenza surveillance, especially the prevention and control of influenza in infants and adolescents.

ObjectiveTo investigate the ameliorative effects and related mechanisms of the Zuogui Jiangtang Shuxin prescription (ZJSP) on glucose and lipid metabolism disorders in MKR mice with diabetic cardiomyopathy (DCM), with a focus on elucidating its regulatory role on the adenosine monophosphate-activated protein kinase (AMPK)/forkhead box protein O1 (FoxO1)/cluster of differentiation 36 (CD36) signaling pathway and lipid deposition. MethodsFifty 8-week-old male MKR mice were fed a high-fat diet for four weeks and then intraperitoneally injected with streptozotocin (STZ) while maintaining a high-fat diet to establish a DCM model. The mice were randomly divided into the model group, the low-dose(14.43 g·kg-1)and high-dose(28.86 g·kg-1) ZJSP groups, and the metformin group (0.25 g·kg-1), with age-matched FVB mice as a normal control group. Each group received intragastric administration of normal saline or corresponding concentrations of ZJSP at equal volumes. After four weeks, fasting blood glucose (FBG) and cardiac function were measured. Blood was collected from the eyeballs under anesthesia to detect fasting insulin (FINS) and blood lipid levels. Myocardial tissue morphology was observed by hematoxylin-eosin (HE) staining, and lipid deposition in the heart was assessed using oil red O staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression levels of AMPK, FoxO1, and CD36 in myocardial tissues. Western blot was employed to detect the protein expression levels of AMPK, p-AMPK, FoxO1, p-FoxO1, and CD36. ResultsCompared with the control group, the model group showed significantly increased levels of FBG and FINS (P<0.01), elevated levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (P<0.01), and significantly decreased left ventricular ejection fraction (EF) and fractional shortening (FS) values (P<0.01). HE staining revealed marked cardiomyocyte hypertrophy, disarray, and widened intercellular spaces in myocardial tissues. Oil Red O staining showed extensive red deposition areas and fine lipid droplet accumulation in the myocardial tissue. AMPK mRNA expression was decreased, while FoxO1 and CD36 mRNA expressions were significantly increased (P<0.01). The p-AMPK/AMPK protein expression ratio in myocardial tissues was significantly reduced, while the p-FoxO1/FoxO1 protein expression ratio and CD36 protein expression levels were significantly increased (P<0.01). Compared with the model group, all treatment groups exhibited significantly reduced FBG (P<0.01), decreased FINS and blood lipid levels (TG, TC, LDL-C) (P<0.05, P<0.01), improved cardiac function (P<0.05), noticeable amelioration of myocardial histopathological morphology and lipid deposition, increased AMPK mRNA expression (P<0.01), with significantly downregulated FoxO1 and CD36 mRNA expressions (P<0.01), elevated p-AMPK/AMPK protein expression levels in myocardial tissue (P<0.05), significantly decreased p-FoxO1/FoxO1 ratios (P<0.01), and downregulated CD36 protein expression levels (P<0.05, P<0.01). ConclusionZJSP exerts a protective effect on the heart in type 2 DCM of MKR mice, and its mechanism may be associated with the regulation of the AMPK/FoxO1/CD36 signaling pathway.

ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription (BSTDP). MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry (UPLC-LIT-Orbitrap-MS). Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction (PPI) network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg (mpx: GFP). At three days post-fertilization (3 dpf), larvae of zebrafish were randomly assigned to blank group, model group, positive drug dexamethasone acetate group (75 μmol·L-1), and BSTDP groups with low, medium, and high doses (500, 1 000, and 2 000 mg·L-1). The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor kappa-B (NF-κB) signaling pathway and inflammatory factors including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) were detected by Real-time quantitative polymerase chain reaction (Real-time PCR). ResultsA total of 120 chemical components were identified in BSTDP, among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis (RA) and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine, vomicine, sinapine, rehmannioside, cinnamyl alcohol glycoside, and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 (Akt1), signal transducer and activator of transcription 3 (STAT3), tumor necrosis factor (TNF), TLR4, mitogen-activated protein kinase 14 (MAPK14), and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (PIK3CA), thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L-1. Compared to those in the blank group, zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region (P<0.01) and rising mRNA levels of TLR4, MyD88, NF-κB, TNF-α, IL-6, and IL-1β (P<0.01). Compared to that in the model group, the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses, as well as the dexamethasone acetate group (P<0.05, P<0.01). There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4, MyD88, NF-κB, TNF-α, IL-6, and IL-1β were significantly down-regulated (P<0.05, P<0.01). ConclusionThis paper identifies the material basis of the efficacy of BSTDP, demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.
