It points out that the core pathogenesis of the disease is the invasion of wind-cold-damp pathogens into the exterior region, leading to stagnation of defensive Yang and obstruction of orifices and collaterals. Through three typical clinical cases (involving symptoms such as nasal itching, nasopharyngeal tube obstruction, nasal congestion with headache), modified ephedra-based formulas such as Mahuang Decoction, Maxing Shigan Decoction, and Xiaoqinglong Decoction are used, combined with drugs for inducing resuscitation, resolving dampness, and promoting blood circulation, to expel pathogens through diaphoresis. Clinical observations show that expelling pathogens with the “diaphoresis method” can effectively relieve symptoms with significant curative effect. This study provides new ideas and methods for expanding the application of the “diaphoresis method” in the treatment of sinusitis.展开更多

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

文摘As cataract surgery progresses from “restoration of sight” to “refractive correction”, precise prediction of intraocular lens (IOL) power is critical for enhancing postoperative visual quality in patients. IOL power calculation methods have evolved and innovated throughout time, from early theoretical and regression formulas to nonlinear formulas for estimating effective lens position (ELP), multivariable formulas, and innovative formulas that use optical principles and AI-based online formulas. This paper thoroughly discusses the development and iteration of traditional IOL calculation formulas, the emergence of new IOL calculation formulas, and the selection of IOL calculation formulas for different patients in the era of refractive cataract surgery, serving as a reference for “personalized” IOL implantation in clinical practice.

文摘Based on Liu Shaowu’s “Exterior Region” theory in the “Three Regions and Six Diseases” doctrine, combined with Zhang Zhongjing’s therapeutic principle of “diaphoresis method”, this paper explores the TCM pathogenesis and treatment methods of cold-damp type allergic rhinitis. It points out that the core pathogenesis of the disease is the invasion of wind-cold-damp pathogens into the exterior region, leading to stagnation of defensive Yang and obstruction of orifices and collaterals. Through three typical clinical cases (involving symptoms such as nasal itching, nasopharyngeal tube obstruction, nasal congestion with headache), modified ephedra-based formulas such as Mahuang Decoction, Maxing Shigan Decoction, and Xiaoqinglong Decoction are used, combined with drugs for inducing resuscitation, resolving dampness, and promoting blood circulation, to expel pathogens through diaphoresis. Clinical observations show that expelling pathogens with the “diaphoresis method” can effectively relieve symptoms with significant curative effect. This study provides new ideas and methods for expanding the application of the “diaphoresis method” in the treatment of sinusitis.

文摘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.

文摘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)_(2)Si 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.

文摘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. 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.

文摘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.

文摘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.
