Lung cancer， with persistently high incidence and mortality rates， remains a significant global health challenge. By taking the study on the experience in diagnosis and treatment of lung cancer with phlegm-dampness and blood stasis syndrome by distinguished traditional Chinese medicine physicians of the Sichuan School as an example， the diagnosis and treatment system for lung cancer with phlegm-dampness and blood stasis syndrome， which was formed in response to the humid and foggy environment of the Sichuan Basin， possesses unique value. However， traditional inheritance modes face challenges such as fragmentation， lack of standardization， and insufficient quantification， which hinder the promotion and application of this experience. This research focused on how to leverage multimodal data and artificial intelligence-generated content （AIGC） to achieve precise analysis， intelligent inheritance， and clinical innovation of the experience in diagnosis and treatment of lung cancer with phlegm-dampness and blood stasis syndrome by distinguished traditional Chinese medicine physicians of the Sichuan School. By integrating multimodal data （encompassing four diagnostic methods of traditional Chinese medicine， modern medical imaging， clinical laboratory tests， molecular biology， and regional environmental information）， a precise diagnosis and treatment system integrating macro and micro perspectives for the "disease， syndrome， and pathogenesis" was constructed. The research yielded the following results： （1） In precise syndrome differentiation， the objective quantification of the phlegm-dampness and blood stasis syndrome was achieved. By constructing a "four diagnostic methods， imaging， and molecule" correlation model， the study revealed intrinsic links between tongue and pulse parameters and the tumor microenvironment， as well as between regional climatic factors and syndrome characteristics， enabling real-time dynamic monitoring of efficacy. （2） In elucidating patterns， the study systematically explored the syndrome differentiation thoughts of Sichuan School physicians， such as the timing of purgation and tonification. A "pathogenesis， syndrome complex， and prescriptions and herb" network model was constructed， which accurately elucidated the synergistic action mechanisms of core herb pairs and quantified the dynamic compatibility patterns of reinforcing healthy Qi and eliminating pathogenic factors. （3） In intelligent empowerment， an auxiliary system integrating intelligent syndrome differentiation， treatment plan generation， and efficacy evaluation was built. This system can fuse regional characteristics with individual data， dynamically generate and optimize personalized prescriptions aligned with the experience of Sichuan School， and predict efficacy trends and potential adverse reactions. The integration of multimodal data and AIGC can effectively facilitate the structured inheritance and clinical translation of distinguished physicians' experience. The established intelligent diagnosis and treatment model integrating traditional Chinese medicine and Western medicine demonstrates clear potential in prolonging patients' progression-free survival， alleviating symptoms， and reducing adverse reactions to treatment. This study provides a referential methodological framework for the traditional Chinese medicine experience in diagnosis and treatment of lung cancer， especially the empirical inheritance and modernized development of regional academic schools. It contributes to advancing clinical diagnosis and treatment toward greater precision and personalization.

Hepatic fibrosis（HF） is a common pathological link of a variety of chronic hepatic diseases， and its complex pathological mechanism and prolonged clinical course pose a major challenge to modern medicine. Modern conventional therapies for HF cannot reverse the pathological vascular remodeling of the liver， and targeted vascular treatment for HF is a current research hotspot. There is a contradiction between the inhibition of pathological repair and the promotion of physiological regeneration with a single targeted therapy. The dynamic equilibrium concept of "achieving equilibrium of Yin and Yang" of traditional Chinese medicine can provide a new treatment strategy， and multi-target traditional Chinese medicine compounds can achieve two-way regulation of pathological mechanisms. According to the research on the modernization of traditional Chinese medicine， the "collaterals and vascular system" are highly compatible in structure and function， and they can guide the treatment of HF at different stages by identifying their common pathological links in HF. The intrahepatic collaterals are an important component of the hepatic collaterals， and the theory of "hepatic collateral disease" based on this physiology has important guiding significance for the clinical diagnosis and treatment of HF. Hepatic sinusoidal obstruction caused by endothelial dysfunction in the early stage of HF is a pathological manifestation of stagnant nutrient Yin in collateral passages. It can be treated by diffusing Qi to resolve stagnation and promoting circulation to unblock collaterals. Repeated stimulation of angiogenesis by hypoxia and inflammation in the medium stage is the pathological manifestation of lingering stagnation of damp and heat in collateral passages. It can be treated by clearing and draining damp and heat， eliminating turbidity， and unblocking collaterals. Pathological vascular remodeling induced by hemodynamic abnormalities in the later stage is a pathological manifestation of the consumption of collateral passages by pathogenic toxins. At this stage with excessive pathogenic factors and deficient healthy Qi， combined therapy of dredging and nourishing is adopted to eliminate toxins， resolve blood stasis， nourish Yin， and supplement Qi simultaneously. Moreover， the holistic concept of harmony between human and nature in traditional Chinese medicine emphasizes the time， place， and treatment based on individual conditions， so the practical application of the theory should consider the specific regional characteristics. This paper aims to discuss the characteristics of pathogenesis， treatment principles， prescriptions， and medicines in different stages of HF based on the correlation between "collaterals and vascular system" as well as the theory of "hepatic collateral disease". It was proposed that Qi deficiency and collateral obstruction were the core pathogenesis of HF， and that hepatic collateral damage was the core pathological basis for the deterioration and prognosis of HF. The scientific connotation and pathogenesis evolution of collateral damage and mass generation in HF were discussed. Sichuan was taken as an example to investigate the treatment of HF according to local conditions， providing new ideas for the treatment of HF.

Diabetes, hyperlipidemia, and hyperuricemia have emerged as global chronic metabolic disorders posing significant public health challenges. Edible medicinal plants demonstrate multitarget regulatory effects and favorable safety profiles in the management of chronic metabolic diseases, owing to their bioactive compounds and nutritional synergy. Radix Astragali (RA), a traditional Chinese medicine with medicine–food homology, has a long history of application in China. Based on a review of relevant literature, this article discusses the historical background, modern research, therapeutic functions, and mechanisms of RA in the treatment of chronic metabolic diseases. Modern studies have shown that RA contains a variety of bioactive components and demonstrates efficacy in managing diabetes, hyperlipidemia, and hyperuricemia. Its mechanisms of action involve modulation of the insulin signaling pathway, regulation of lipid metabolism-related enzyme activity, promotion of uric acid excretion, and other processes. Notably, RA exhibits certain common therapeutic effects across hyperglycemia, hyperlipidemia, and hyperuricemia. Through modulation of the gut microbiota and inhibition of inflammatory pathways, RA exerts synergistic, multitarget effects that improve metabolic disorders associated with chronic metabolic diseases.

ObjectiveTo evaluate the clinical efficacy of modified Zhishi Daozhi decoction in treating patients with metabolic associated fatty liver disease （MAFLD） due to dampness-heat and stasis obstruction. MethodsA randomized controlled trial design was adopted， with patients diagnosed with MAFLD due to dampness-heat and stasis obstruction treated in the Department of Endocrinology， Metabolism， and Gastroenterology at the Third Affiliated Hospital of Changchun University of Chinese Medicine between November 2023 and November 2024 as the study subjects. A total of 126 patients who met the inclusion criteria were randomized into an observation group and a control group， with 63 patients in each group. The observation group was administered the granule preparation of modified Zhishi Daozhi decoction， while the control group received Xuezhikang capsules orally. Both groups underwent a 12-week treatment course. The two groups before and after treatment were compared in terms of obesity indicators ［body weight， body mass index （BMI）， waist circumference （WC）， weight-adjusted waist circumference index （WWI）， and waist-to-hip ratio （WHR）］， lipid indicators ［total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C）］， liver function indicators ［alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and gamma-glutamyl transpeptidase （GGT）］， liver ultrasound imaging， traditional Chinese medicine （TCM） symptom scores， and Patient-Reported Outcome （PRO） scale scores at follow-up. Results① After treatment， the body weight， BMI， and levels of TC， TG， and LDL-C declined in both groups （P<0.05， P<0.01）， and the observation group demonstrated larger reductions in BMI， WC， LDL-C （P<0.05）， and WHR （P<0.01）. The levels of ALT， AST， and GGT declined in the observation group after treatment （P<0.05）， whereas no statistically significant differences in the three indicators were observed in the control group before and after treatment. Subgroup analysis based on normal vs. abnormal liver function revealed intergroup differences only in the abnormal liver function cohort. After treatment， the observation group demonstrated greater reductions in ALT （P<0.01） and AST （P<0.05） than the control group. ② The total response rate of liver ultrasound imaging was 79.24% （42/53） in the observation group and 62% （31/50） in the control group. Post-treatment comparison showed that the observation group （χ²=21.311， P<0.01） achieved greater alleviation of fatty liver disease severity. ③ The total response rate of TCM syndrome was 94.34% （50/53） in the observation group and 66% （33/50） in the control group， with the observation group demonstrating superior efficacy （χ²=26.78， P<0.01）. Compared with the control group post-treatment， the observation group showed enhanced reductions in the total TCM symptom score （P<0.01） and individual symptom scores of rib distension and pain， sticky and unsmooth stools， obesity with abdominal distension， sticky sensation in the mouth， and yellowish-red urine （P<0.01）. ④ After treatment， the PRO score improved in both groups （P<0.01）， and the increase was larger in the observation group （P<0.01）， primarily reflected in the physiological dimension （P<0.01）. ConclusionModified Zhishi Daozhi decoction shows definite efficacy in treating MAFLD patients with the syndrome of dampness-heat and stasis obstruction， with effects of alleviating abdominal obesity and regulating blood lipids. Additionally， it positively impacts patients quality of life， as evidenced by the changes in TCM symptom and PRO scores.

BACKGROUND:Ca2+expression in astrocytes has been found to be closely related to cognitive function,and the Ca2+signaling pathway regulated by inositol 1,4,5-trisphosphate receptors(IP3R2)and ryanodine receptor(RYR)2 receptors has become a hot spot in the study of cognitive disorder-related diseases. OBJECTIVE:To investigate the expression of Ca2+signals mediated by IP3R2 and RYR2 in hippocampal astrocytes in animal models of delayed encephalopathy after acute carbon monoxide poisoning,and to explore the possible pathogenesis of delayed encephalopathy after acute carbon monoxide poisoning. METHODS:C57BL mice with qualified cognitive function were selected by Morris water maze experiment and randomly divided into control group and experimental group.An animal model of delayed encephalopathy after acute carbon monoxide poisoning was established by static carbon monoxide inhalation in the experimental group,and the same amount of air was inhaled in the control group.Behavioral and neuronal changes,astrocyte specific marker glial fibrillary acidic protein,IP3R2,RYR2 receptor and Ca2+concentration in astrocytes of the two groups were detected using Morris water maze,hematoxylin-eosin staining,western blot,immunofluorescence double labeling and Ca2+fluorescence probe at 21 days after modeling. RESULTS AND CONCLUSION:In the Morris water maze,the escape latency of the experimental group was significantly longer than that of the control group(P<0.05).Hematoxylin-eosin staining results showed that in the experimental group,the number of hippocampal pyramidal cells decreased,the cell structure was disordered,and the nucleus was broken and dissolved.Immunofluorescence results showed that IP3R2 and RYR2 were co-expressed with glial fibrillary acidic protein in the hippocampus,and the expressions of IP3R2,RYR2 and glial fibrillary acidic protein were up-regulated in the hippocampus of the experimental group(P<0.05).Western blot analysis showed that the expressions of IP3R2,RYR2,and glial fibrillary acidic protein in the hippocampus of the experimental group were increased(P<0.05).Ca2+concentration in hippocampal astrocytes increased significantly in the experimental group(P<0.05).To conclude,astrocytes may affect Ca2+signals by mediating IP3R2 and RYR2 receptors,then impair the cognitive function of mice with carbon monoxide poisoning,and eventually lead to delayed encephalopathy after acute carbon monoxide poisoning.

BACKGROUND:Research has shown that vanillic acid has anti-inflammatory and anti-oxidative stress effects,but it is unclear whether it has a protective effect on endplate chondrocytes.OBJECTIVE:To explore the effect and mechanism of vanillic acid on endplate chondrocytes under inflammatory microenvironment.METHODS:(1)Primary endplate chondrocytes were isolated from the intervertebral disc of SD rats and identified by toluidine blue staining and collagenⅡ immunofluorescence.(2)The CCK-8 assay was employed to detect the effects of interleukin-1β and vanillic acid on the proliferation activity of endplate chondrocytes,in order to determine the concentration of vanillic acid for subsequent cell treatment.(3)An inflammatory microenvironment was simulated by adding 10 ng/mL interleukin-1β to the culture medium,and the endplate chondrocytes were treated with low,medium,and high mass concentrations of vanillic acid.The expression levels of inflammatory markers and extracellular matrix proteins were detected by western blot assay and immunofluorescence.(4)The expression of nuclear factor κB signaling pathway-related proteins was detected by western blot assay.RESULTS AND CONCLUSION:(1)The morphology of endplate chondrocytes in adherent culture was pike or triangular in shape,positive for toluidine blue staining and immunofluorescence for collagen Ⅱ,indicating that the experimentally extracted cells were endplate chondrocytes.(2)The CCK-8 assay results showed that treatment with 2.5,5,10,and 20 μg/mL vanillic acid for 24 hours did not significantly inhibit the proliferation of endplate chondrocytes.Compared with the interleukin-1β group,the viability of endplate chondrocytes treated with 5,10,and 20 μg/mL vanillic acid for 24 hours was significantly increased(P＜0.05).Therefore,5,10,and 20 μg/mL vanillic acid was selected as the low,medium,and high dose groups for subsequent treatment of endplate chondrocytes.(3)Compared with the model group(complete medium containing 10 ng/mL interleukin-1β),the expression of NOD-like receptor thermal domain associated protein 3(NLRP3),matrix metalloproteinase 13,matrix metalloproteinase 3,and tumor necrosis factor alpha protein in the endplate chondrocytes of the low,medium,and high doses of vanillic acid groups were significantly reduced(P＜0.05).(4)Compared with the model group,the protein expression of aggrecan and collagen Ⅱ in the endplate chondrocytes of the low,medium,and high dose groups of vanillic acid significantly increased(P＜0.05).(5)Compared with the model group,the protein expression of phospho-nuclear factor κB and phospho-inhibitor of nuclear factor κB in the endplate chondrocytes of the low,medium,and high dose groups of vanillic acid was significantly reduced(P＜0.05).(6)The above results indicate that vanillic acid may alleviate the inflammatory response and extracellular matrix degradation induced by interleukin-1β in rat endplate chondrocytes by inhibiting the activation of the nuclear factor κB signaling pathway.

Objective:To explore the mechanism through which the Ginkgo biloba extract(EGb)ameliorates depres-sion-like behaviors in chronic copper-exposed mice.Methods:A mouse model with depression was induced by chronic oral administration of copper sulfate solution(200 mg/L),followed by oral administration of the EGb(120 mg/L)for one month.Elevated plus-maze test,forced swimming test,and sucrose preference test were employed to detect the de-pression-like behaviors of mice.TUNEL staining was utilized to examine apoptosis in the hippocampal region of mice.Immunohistochemistry was adopted to detect the in situ expression of pro-brain-derived neurotrophic factor(proBDNF)and brain-derived neurotrophic factor(BDNF)in the hippocampal region.RT-qPCR was used to measure the expression of the BDNF mRNA.Western blot was utilized to determine the expressions of proteins such as proBDNF,mature BDNF(mBDNF),cAMP response element binding protein(CREB),phospho-CREB(p-CREB),tyrosine kinase receptor B(TrkB),p75 neurotrophin Receptor(p75NTR),furin,proprotein convertase subtilisin/kexin type 1(PCSK1),and matrix metalloproteinase-9(MMP9).Results:Chronic copper exposure led to depression-like behaviors in mice,in-creased neuronal apoptosis in the hippocampal region,enhanced proBDNF expression and reduced mBDNF expression(P＜0.05),decreased the expression of the downstream receptor protein TrkB and increased the expression of p75NTR(P＜0.05),and decreased the level of CREB and p-CREB(P＜0.05).Meanwhile,the expressions of intracellular proteases furin and PCSK1 in the hippocampal region of mice with depression-like behaviors decreased(P＜0.05),while the expression of extracellular protease MMP9 increased(P＜0.05).EGb was capable of alleviating depression-like behaviors and neuronal apoptosis in mice and partially reversing the abnormal expressions of BDNF,proBDNF,TrkB,p75NTR,CREB,p-CREB,furin,and PCSK1 proteins caused by copper exposure.Conclusion:Chronic copper exposure can lead to depression-like behaviors and apoptosis in mice.EGb can reverse these manifestations and corre-late with the balance of proBDNF/BDNF in the hippocampal region,which may offer novel insights for the treatment of depression.
