METHODS: A chronic asthma rat model was established using ovalbumin(OVA) combined with aluminum hydroxide sensitization and OVA nebulization stimulation. Lung tissue pathology was assessed via hematoxylin and eosin staining and periodic acid-Schiff staining. Lung tissue ultrastructure was observed using transmission electron microscopy. Serum cytokine levels were measured by enzyme-linked immunosorbent assay. Malondialdehyde(MDA), glutathione, and tissue ferrous ion content in rat lung tissues and cells were detected using commercial kits. Immunohistochemical staining was used to determine the expression levels of interleukin-13(IL-13) and interleukin-6(IL-6) in lung tissue. Western blotting was employed to detect the expression levels of transferrin receptor 1(TFR1), transferrin receptor 2(TFR2), acyl-Co A synthetase longchain family member 4(ACSL4), glutathione peroxidase 4(GPX4), and solute carrier family 7 member 11(SLC7A11). Cell proliferation, apoptosis and reactive oxygen species(ROS) were evaluated using a cell counting kit-8 assay and flow cytometry. Intracellular lipid peroxidation was detected using a C11-BODIPY 581/591(C11-BODIPY) probe. RESULTS: SFYC formula effectively alleviates airway inflammation in asthmatic rats in a dose-dependent manner. It improves airway epithelial cell integrity, reduces alveolar wall thickening and expansion, inhibits goblet cell proliferation and mucus secretion, and decreases the expression of IL-6 and IL-13 in lung tissue, as well as the serum levels of IL-6, IL-13, interleukin-4(IL-4), and immunoglobulin E(Ig E). SFYC formula mitigates ferroptosis in lung tissue of asthmatic rats. At the cellular level, it promotes proliferation of rat airway epithelial cells, inhibits cell apoptosis, suppresses ROS, MDA, and lipid accumulation, reduces the expression of TFR1, TFR2, and ASCL4, and increases the expression of GPX4 and SLC7A11 to mitigate ferroptosis. CONCLUSION: SFYC formula alleviates asthma airway inflammation by inhibiting ferroptosis in airway epithelial cells, providing new insights and potential therapeutic targets for the development of new asthma treatment drugs.展开更多

摘要A Cu-1.9Ni-1.9Co-0.9Si(mass fraction,%)alloy with high strength and electrical conductivity was designed by cluster formula approach.The microstructure evolution of the alloy during thermomechanical treatment was systematically investigated.The strengthening mechanism and electrical conductivity of the alloy were discussed in detail.The optimal thermomechanical treatment process was as follows:solid solution→80%cold rolling→(450℃,4 h)aging→50%cold rolling→(400℃,4 h)aging.The designed alloy achieved excellent comprehensive properties with a microhardness of HV 260,a yield strength of 843 MPa,a tensile strength of 884 MPa,and an electrical conductivity of 42.6%(IACS).Compared to direct aging treatment,the designed alloy subjected to multi-stage thermomechanical treatment had refined grains,high density of dislocations,and accelerated of precipitation of(Ni,Co)2Si precipitates.High strength was mainly attributed to the combined effect of dislocation strengthening,work hardening and sub-grain strengthening,while good electrical conductivity was maintained through the precipitation of the large number of nanoparticles.
基金Supported by Natural Science Foundation-funded Project:the Study on the Mechanism of Soufeng Yuchuan Formula in Regulating Airway Remodeling in Asthmatic Rats Based on Epithelial-Mesenchymal Transition(No. 82174438)。
摘要OBJECTIVE: To explore whether Soufeng Yuchuan(搜风愈喘, SFYC) formula alleviates asthma by promoting ferroptosis of airway epithelial cells. METHODS: A chronic asthma rat model was established using ovalbumin(OVA) combined with aluminum hydroxide sensitization and OVA nebulization stimulation. Lung tissue pathology was assessed via hematoxylin and eosin staining and periodic acid-Schiff staining. Lung tissue ultrastructure was observed using transmission electron microscopy. Serum cytokine levels were measured by enzyme-linked immunosorbent assay. Malondialdehyde(MDA), glutathione, and tissue ferrous ion content in rat lung tissues and cells were detected using commercial kits. Immunohistochemical staining was used to determine the expression levels of interleukin-13(IL-13) and interleukin-6(IL-6) in lung tissue. Western blotting was employed to detect the expression levels of transferrin receptor 1(TFR1), transferrin receptor 2(TFR2), acyl-Co A synthetase longchain family member 4(ACSL4), glutathione peroxidase 4(GPX4), and solute carrier family 7 member 11(SLC7A11). Cell proliferation, apoptosis and reactive oxygen species(ROS) were evaluated using a cell counting kit-8 assay and flow cytometry. Intracellular lipid peroxidation was detected using a C11-BODIPY 581/591(C11-BODIPY) probe. RESULTS: SFYC formula effectively alleviates airway inflammation in asthmatic rats in a dose-dependent manner. It improves airway epithelial cell integrity, reduces alveolar wall thickening and expansion, inhibits goblet cell proliferation and mucus secretion, and decreases the expression of IL-6 and IL-13 in lung tissue, as well as the serum levels of IL-6, IL-13, interleukin-4(IL-4), and immunoglobulin E(Ig E). SFYC formula mitigates ferroptosis in lung tissue of asthmatic rats.

摘要Chronic heart failure(CHF)impairs cognitive function.Xijiaqi Formula(XJQ),a traditional Chinese medicine(TCM)used clinically to treat CHF,demonstrates potential for improving cognition in CHF patients.However,its precise mechanism in treating post-CHF cognitive dysfunction remains unclear.This study systematically investigates XJQ’s effects on post-CHF cognitive dysfunction and the underlying mechanisms.The components of XJQ were identified through liquid chromatography-mass spectrometry.CHF was induced in rats via ligation of the left anterior descending coronary artery,followed by six weeks of XJQ treatment.Cardiac function was evaluated through echocardiography and hemodynamic parameters,while cognitive function was assessed using Morris water maze(MWM)and open field tests(OFT).XJQ treatment enhanced both cardiac and cognitive functions in CHF rats.Network pharmacology identified 12 core active components of XJQ and indicated its effect on cognitive dysfunction involved regulating synapses,inflammation,and phosphodiesterase 4(PDE4)-dependent cyclic adenosine monophosphate(cAMP)signaling.XJQ inhibited microglial and astrocyte activation,decreased proinflammatory cytokines,and mitigated neuronal damage.Notably,XJQ promoted synaptic repair and dendritic growth by downregulating PDE4 and upregulating cAMP,protein kinase A(PKA),cAMP-response element binding protein(CREB),brain-derived neurotrophic factor(BDNF),PSD95,and synapsin I levels.Molecular docking and Bio-layer interferometry assays confirmed direct binding of quercetin,kaempferol,isorhamnetin,and darutoside to PDE4.In conclusion,XJQ alleviates neuroinflammation and enhances synaptic plasticity to improve cognitive dysfunction in CHF rats via the PDE4/cAMP/PKA/CREB signaling pathway.These findings provide valuable insight into the heart-brain axis.

摘要Background:Hua-Yi-Jie-Du formula(HYJD)is a traditional Chinese medicine that has proven effective against viral pneumonia and was extensively used during the COVID-19 pandemic.This study investigates how HYJD influences group 2 innate lymphoid cell(ILC2)and nucleotide oligomerization domain(NOD)-like receptor protein 3(NLRP3)inflammasome activation in a mouse model of viral pneumonia.Methods:A mouse model of viral pneumonia was established through the administration of polyinosinic-polycytidylic acid(poly(I:C))via nasal drops.Histopathological analysis of lung tissue was conducted,alongside enzyme-linked immunosorbent assay to quantify cytokine levels in serum and bronchoalveolar lavage fluid(BALF).Flow cytometry was employed to detect ILC2 cells in lung tissue and spleen,while immunofluorescence techniques were utilized to visualize ILC2 cells in lung tissue.Transcriptomic sequencing was performed,and the results were validated using qRT-PCR and western blot analysis.Results:HYJD significantly ameliorated inflammatory infiltration in lung tissue,decreased mucus protein secretion,and reduced the serum levels of inflammatory cytokines interleukin(IL)-1β,IL-6,and tumor necrosis factor-alpha(TNF-α).Additionally,it lowered the expression of cytokines IL-4,IL-5,IL-13,IL-25,thymic stromal lymphopoietin(TSLP),and IL-33 in BALF,and reduced the differentiation of ILC2 cells in both lung tissue and spleen.Transcriptomic analysis and experimental validation revealed that HYJD downregulated the expression of NLRP3 related genes and proteins within the NOD-like receptor signaling pathway.Conclusion:The mechanism by which HYJD intervenes in acute lung injury associated with viral pneumonia may involve the reduction of ILC2 cells differentiation and the inhibition of NLRP3 activation.
摘要BACKGROUND Infantile colic(IC)is a common,self-limiting condition marked by excessive,unexplained crying.Evidence on the use of extensively hydrolyzed formulas(eHFs)as a dietary intervention remains fragmented.AIM To systematically review and meta-analyze the effectiveness of eHFs in managing symptoms of IC.METHODS A comprehensive literature search of MEDLINE,Cochrane and Web of Science databases(1980-2025)identified randomized controlled trials and crossover studies assessing the efficacy of eHF in infants diagnosed with IC based on Wessel’s or ROME III criteria.Studies were included if they involved infants≤6 months old on partial or exclusive formula diets,and were excluded if the diagnosis was unclear.Data were synthesized qualitatively and through meta-analysis using odds ratios(OR)and 95%confidence intervals(CI).RESULTS Six studies met the inclusion criteria,with a total of 340 infants across intervention and comparator arms.In all studies,eHF significantly reduced crying duration and colic symptoms compared to regular formula or dicyclomine.The meta-analysis showed a pooled OR of 4.8(95%CI:2.53-9.11,P<0.05).Secondary outcomes such as stool consistency and parental quality of life were variably reported but tended to favor eHF.CONCLUSION eHF appear significantly more effective than standard formulas and pharmacologic comparators in reducing colicrelated symptoms.These findings support eHF as a viable dietary intervention for IC,though larger,wellcontrolled trials are warranted to confirm long-term outcomes.

摘要OBJECTIVE:To confirm the efficacy of Yiqi Huoxue formula(益气活血方,YQHX)on heart failure with reduced ejection fraction(HFr EF),and elucidate its potential effect on calcium homeostasis.METHODS:Cardiac specific calcium/calmodulindependent protein kinase II delta C isoform(Ca MKⅡδC)-overexpression transgenic mice(C-Ca MKⅡδC+/-Tg mice)and calcium/calmodulin-dependent protein kinase II delta B isoform(Ca MKⅡδB)-overexpression transgenic mice(C-Ca MKⅡδB+/-Tg mice)were established by clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9 technique,and their genotypes and phenotypes were identified thereafter.C57BL/6 mice and transgenic mice were divided into seven groups in random,each containing eight mice.The groups were Control group,Ca MKⅡδB model group,Ca MKⅡδB treatment group(B Treated),Ca MKⅡδB inhibitor group(B Inhibitor),Ca MKⅡδC model group(C Model),Ca MKⅡδC treatment group(C Treated),Ca MKⅡδC inhibitor group(C Inhibitor).B and C Treated groups were given YQHX once a day for 4 weeks by gavage.The cardiac function and structure were evaluated using echocardiogram.The myocardial cellular status and fibrosis were detected by hematoxylin and eosin staining and Masson staining.Calcium transients and calcium leakage from cardiac ventricular myocytes were detected to reflect calcium homeostasis,and the expressions of Ca MKⅡδB,Ca MKⅡδC,hypertrophy factors,calcium pathway-related genes,and the level of calcium handling proteins were assessed by western blotting and reverse transcription-quantitative polymerase chain reaction.RESULTS:We found Ca MKⅡδB and Ca MKⅡδC transgenic mice showed HFr EF phenotype.YQHX improved the systolic function of the Ca MKⅡδB transgenic mice,reduced the cross-sectional area of cardiomyocytes,inhibited the overexpression of Ca MKⅡδB and hypertrophy-related genes(B-type natriuretic peptide,myocyte enhancer factor 2,and atrial natriuretic factor),and increased calcium handling protein sarcoendoplasmic reticulum Ca^(2+)adenosine triphosphatase 2a(SERCA2a)and calcium capacity.YQHX improved the cardiac systolic function of Ca MKⅡδC transgenic mice,reduced the ventricular diameter and cardiomyocyte cross-sectional area,alleviated myocardial fibrosis,increased SERCA2a expression and calcium capacity,and reduced calcium leakage.CONCLUSION:Our results suggest that YQHX improved HFr EF by inhibiting Ca MKIIδB overexpression,which may be related to reduced expression of hypertrophyrelated factors,and increased SERCA2a expression to increase calcium reserve.In addition,YQHX improved HFr EF by inhibiting Ca MKIIδC overexpression,which may be related to reduce calcium leakage,and increase SERCA2a expression to increase calcium reserve.

摘要Triacylglycerol(TAG)components in human milk,infant formulas with different fat sources,and plant oils(palm oil,flaxseed oil,sunflower oil,corn oil,soybean oil,coconut oil,low erucic acid rapeseed oil,and high oleic acid rapeseed oil)were analyzed and compared using ultraperformance supercritical fluid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPSFC-Q-TOF-MS).Distinct TAG profiles were identified by lipidomics,principal component analysis(PCA),and heatmap visualization.Human milk was characterized by a high abundance of medium-and long-chain triacylglycerols(MLCTs),saturated-unsaturated-unsaturated(SUU)-type TAGs(sn-2 palmitic acid).In contrast,plant oils lacked MLCTs and SUU-type TAGs,containing mainly TAGs esterified long-chain polyunsaturated fatty acid.Breast milk contains about 27%MLCT,about 50%SUU-type triacylglycerols(which contain about 34%UPU-type triacylglycerols),which is significantly different from plant oils,structured fats and infant formulas.These findings provide a clear basis for optimizing the fat blend in infant formula to better mimic the unique TAG profile of human milk,thereby improving energy delivery and nutrient absorption for infants.

摘要BACKGROUND Colitis-associated colorectal cancer(CAC)is a common type of malignant tumor that occurs in the digestive tract and poses a significant threat to human health.The traditional Chinese medicine preparation Hua-Zhuo-Jie-Du formula(HZJDF)has shown clinical efficacy in preventing CAC;however,the potential therapeutic mechanisms of this formula for treating CAC remain under explored.AIM To investigate the therapeutic efficacy and mechanism of HZJDF against CAC through applying an integrated research approach.METHODS We first established a CAC mouse model using the azoxymethane/dextran sulfate sodium induction method and then assessed the therapeutic effects of various doses of HZJDF on the CAC mice.Subsequently,we utilized a combination of network pharmacology and transcriptomics analyses to help predict the potential mechanisms by which HZJDF acts against CAC.Finally,we sought to validate these prediction findings through animal and cell experiments.RESULTS HZJDF significantly mitigated weight reduction and colon length shortening in a dose-dependent manner,enhanced the mice survival rates,lowered the disease activity index scores,diminished the tumor incidence and burden,and improved the pathological condition of the colon tissues in the CAC mice.The findings from the network pharmacology and transcriptomics analyses suggested that the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)signaling pathway might be the potential mechanism through which HZJDF exerts its protective effects against CAC.In vivo studies showed that HZJDF diminished the quantity of Ki67-positive cells within the colon tissues of the CAC mice and lowered the levels of phosphorylated PI3K and AKT proteins.Meanwhile,in vitro studies indicated that serum containing HZJDF decreased the viability,proliferation,and migration of HT-29 and HCT116 cells in a dose-dependent manner,while also lowering the expression of key proteins linked to the PI3K/AKT signaling pathway.CONCLUSION HZJDF effectively alleviated CAC tumorigenesis by suppressing the PI3K/AKT signaling pathway,providing reliable evidence to support the appropriate utilization of HZJDF in CAC treatment.

摘要OBJECTIVE:To investigate the pharmacological effects and underlying mechanisms of Pinggan Yuyin Qingre formula(平肝育阴清热方,PGYYQR)in the treatment of meibomian gland dysfunction(MGD)through network pharmacology and in vivo validation.METHODS:A mouse model of MGD was induced using the stearoyl-coenzyme a desaturase 1 inhibitor,followed by PGYYQR treatment for 2 weeks.MGD sign scoring,hematoxylin and eosin(HE)staining,oil red o(ORO)staining,and serum inflammatory cytokine analysis were conducted to assess the effects of PGYYQR on meibomian gland(MG)function,histopathology,and associated inflammation.Network pharmacology was employed to identify the active compounds and potential targets of PGYYQR.Molecular mechanisms were further investigated using Western blotting,reverse transcription quantitative real-time polymerase chain reaction,and reactive oxygen species(ROS)assays.RESULTS:PGYYQR treatment significantly reduced the scores of MG orifice obstruction and meibum quality in MGD mice.HE and ORO staining further demonstrated that PGYYQR ameliorated glandular damage and lipid dysfunction.Enzyme-linked immunosorbent assay results revealed that PGYYQR markedly decreased the serum levels of key inflammatory cytokines,including interleukin(IL)-1β,IL-6,and tumor necrosis factor-α.Network pharmacology identified 162 active compounds and 598 target genes in PGYYQR.Among these,IL-6,IL-1β,matrix metalloproteinase-9,and C-X-C motif chemokine ligand 8 were recognized as core targets related to MGD and were mainly enriched in the IL-17uclear factor kappa B(NF-κB)signaling pathway.Further molecular analyses confirmed that PGYYQR significantly inhibited the IL-17/NF-κB axis by downregulating IL-17 expression and reducing phosphorylated NF-κB p65 levels at both the protein and m RNA levels in MG tissues.PGYYQR also effectively reduced ROS levels in the conjunctival tissues of MGD mice.CONCLUSION:PGYYQR effectively improves MG function and preserves local tissue morphology in MGD model mice,primarily by suppressing the inflammatory response through coordinated modulation of the IL-17/NF-κB signaling pathway and oxidative stress.

摘要BACKGROUND Glycolipid metabolic disorder includes a series of chronic diseases that are closely associated with disturbances in both glucose and lipid metabolism.Jiangtang Tiaozhi formula(JTTZF)demonstrating significant hypoglycemic,lipidmodifying,and anti-inflammatory effects.However,the specific molecular mechanisms underlying JTTZF’s hepatoprotective effects and its ability to ameliorate glycolipid metabolic disorder remain largely unexplored.AIM To investigate how JTTZF improves glycolipid metabolic disorder using hepatic transcriptome and metabolome analyses.METHODS To induce glycolipid metabolic disorder,male C57BL/6J mice were fed a high-fat diet(HFD)for 12 weeks,after which they received an 8-week administration of JTTZF.Liver tissues were analyzed using transcriptomics and metabolomics.Real-time quantitative polymerase chain reaction validated key gene expression.RESULTS Metabolomics data revealed that JTTZF significantly regulated HFD-induced alterations in glycolipid metabolism,with notable changes in pathways such as the pentose phosphate pathway,steroid hormone biosynthesis,and purine metabolism.Transcriptomics profiles indicated that JTTZF exerted regulatory effects on lipid and glucose metabolism,primarily through pathways including peroxisome proliferators-activated receptor signaling,drug metabolism other enzymes,and regulation of lipolysis in adipocytes.Real-time quantitative polymerase chain reaction confirmed that JTTZF modulated pivotal genes associated with fatty acid synthesis,lipolysis,insulin resistance,energy metabolism,and inflammation.These findings suggest that JTTZF may act through multiple pathways to improve glycolipid metabolic disorder.CONCLUSION JTTZF can ameliorate the glycolipid metabolic disorder induced by HFD-diet by regulating lipid metabolism and improving insulin tolerance.
摘要This paper presents new formulas for estimating the translational and rotational time periods of the prevailing reinforced concrete shear-wall multistory buildings(SWMBs)in Egypt.Forty distinct structural plans,featuring varying lateral and torsional stiffness,were rigorously prepared to create a sample of 142 SWMBs,with diverse heights,concrete strengths,and stiffness properties.A three-dimensional finite element modal analysis was conducted on the sample,and the first three vibration modes were identified.Regression analyses were performed using multiple combinations of eighteen geometric and mechanical parameters to derive the most accurate and simplest formulas for the translational and rotational periods.Additionally,lower-bound translational formulas were proposed for code implementation.Compared with reference modal analyses and period estimates calculated using the Egyptian code(ECL 201)alongside three international seismic codes—EC8,IBC,and UBC—the proposed formulas demonstrated superior reliability(95%based on a new criterion),followed by the UBC(61%)and ECL(56%).While the ECL ensured the safety of all buildings,it exhibited excessive conservativeness in underestimating the periods.The proposed formulas mitigated this conservativeness by ensuring only marginal underestimation of the time periods,thereby improving economic viability.Furthermore,the correct order of the first three vibration modes was effectively distinguished.

摘要BACKGROUND Tangwang formula(TWF),a traditional Chinese medicine,has been shown to delay the progression of diabetic retinopathy(DR)over the past 20 years.However,the potential therapeutic mechanisms and effective components of TWF remain unclear.AIM To investigate the effective components of TWF and elucidate the mechanism underlying TWF treatment for DR.METHODS The chemical ingredients of TWF were detected using high-pressure liquid chromatography.Network pharmacology and molecular docking were applied to identify the targets and pathways associated with TWF and DR.A DR mouse model was established by streptozotocin to evaluate the therapeutic effect of TWF in vivo.High glucose treatment was used to induce injury in mouse retinal endothelial cells(mRECs)to verify the mechanism of TWF in vitro.The 16S ribosomal RNA sequencing and untargeted metabolomics were performed to detect intestinal bacteria and fecal metabolites in DR mice.RESULTS Eight important active constituents were identified by high-pressure liquid chromatography.Network pharmacology results showed that Bcl2 and Casp3 were key targets between TWF and DR.Isorhamnetin-3-O-neohespeidoside,naringenin,ononin,and calycosin-7-O-β-D-glucoside from TWF had strong affinities with Bcl2 and Casp3.TWF significantly reduced random blood glucose,inhibited the levels of proinflammatory factors in DR mice and mRECs,and alleviated retinal damage by downregulating the expressions of vascular endothelial growth factor and receptor advanced glycation end products,and upregulating the expressions of zonula occludens-1 and RBP-3.TWF inhibited the apoptosis in mouse retinal tissues and mRECs.Analysis of intestinal bacteria and metabolites revealed that TWF increased the richness and evenness of intestinal microbiota and improved fecal metabolic profiles in DR mice.Importantly,seven genus bacteria were closely correlated with amino acids,fatty acids,glycerophosphocholine,and bile acid,which could participate in ameliorating retinal injury.CONCLUSION These findings suggest that TWF may ameliorate retinal damage in DR mice via anti-inflammatory and antiapoptotic activities,which may be associated with modulation of the intestinal microbiota and metabolic profiles.
