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.

ObjectiveTo investigate the current status of assistive device use and unmet needs among persons with disabilities in Sichuan-Chongqing region, and to identify the key factors associated with satisfaction with these devices. MethodsFrom October, 2024 to February, 2025, quota sampling was adopted to recruit 1 040 persons with disabilities in Sichuan and 260 persons with disabilities in Chongqing. Telephone and online questionnaires were used to collect data on demographic characteristics, status of assistive device utilization and unmet assistive device needs, as well as satisfaction with assistive device use. Correlation analysis, multiple linear regression analysis and structural equation modeling were performed to identify key factors associated with satisfaction. ResultsA total of 1 186 valid responses were collected, of which 942 were from Sichuan Province and 244 from Chongqing Municipality. The utilization rate of assistive devices among persons with disabilities in Sichuan-Chongqing region was 61.9%, and the rate of unmet assistive device needs was 30.6%. The assistive device utilization rate of participants with agricultural household registration (57.98%) was lower than that of participants with non-agricultural household registration (66.86%). The utilization rate showed a J-shaped upward trend with the increase of educational attainment. Educational attainment (P = 0.002), perceived usefulness of assistive devices (P < 0.001), home living environment (P < 0.001), public environment (P < 0.001) and disability type (significant differences were found in visual and hearing disabilities compared with physical disability, P < 0.05) were key predictors of satisfaction with assistive device use. The impact of public environment on satisfaction was exerted through two indirect mediating paths: mediating effect via perceived usefulness of assistive devices (ind₁ = 0.357, 95%CI 0.279 to 0.437, P < 0.001), contributing approximately 70% of the total indirect effect; mediating effect via home living environment (ind₂ = 0.129, 95%CI 0.006 to 0.242, P = 0.038), contributing approximately 25% of the total indirect effect. ConclusionThere is a structural imbalance between assistive device use and demand in Sichuan-Chongqing region. People with psycho-intellectual disabilities are most likely to be excluded from the service chain because they neither perceive need nor access information. Education exerts a robust positive effect on both adoption and satisfaction, so training content must be tailored to different educational levels. Satisfaction is shaped by disability type, device usefulness and environmental factors. Future product development should therefore integrate functional and psychosocial dimensions. Priority should be given to micro-scale home-and-community accessibility retrofits before extending upward to public transportation and employment settings, to maximize the cost-effectiveness of limited funds.

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.

ObjectiveTo screen for and validate key differentially expressed proteins in serum of patients with metabolic dysfunction‑associated fatty liver disease （MAFLD）， and to provide a basis for identifying diagnostic biomarkers and developing intervention strategies for this disease. MethodsA total of 20 patients who were diagnosed with MAFLD in the third affiliated hospital of Chengdu University of Traditional Chinese Medicine from December 2024 to January 2025 were enrolled as MAFLD group， and 20 healthy controls were enrolled as HC group. Demographic data and serum biochemical parameters were collected from both groups. Data-independent acquisition （DIA） quantitative proteomics was used to measure the relative expression levels of serum proteins， and related methods were used to obtain significantly differentially expressed proteins， including the gene ontology functional enrichment analysis， the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis， protein-protein interaction （PPI） network， Hub node interaction， and weighted gene co-expression network analysis （WGCNA）. Rats were given a high-fat diet to establish a model of MAFLD， and randomly assigned to the control group and model group. Serum biochemical parameters and inflammatory factors were measured， liver histopathological changes were observed， and the protein expression levels of MER proto-oncogene tyrosine kinase （MERTK） and matrix metalloproteinase-9 （MMP-9） in liver tissue were verified. The independent-samples t test was used for comparison of normally distributed continuous data between groups， while the Mann-Whitney U test was used for comparison of non-normally distributed continuous data or data with heterogeneity of variance between groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsCompared with the HC group， the MAFLD group had significant increases in the serum levels of aspartate aminotransferase （t=-7.348， P<0.05）， alanine aminotransferase （Z=5.088， P<0.05）， alkaline phosphatase （t=-3.943， P<0.05）， triglyceride （Z=2.070， P<0.05）， and high-density lipoprotein cholesterol （t=3.867， P<0.05）. A total of 3 559 proteins were identified by DIA serum proteomics， among which 160 differentially expressed proteins were mainly enriched in pathways including metabolic disorders， immune inflammatory response， and extracellular matrix remodeling. The PPI network and the Hub node analysis showed that serpin family E member 1， MMP-9， and intercellular cell adhesion molecule-1 were core regulatory proteins. WGCNA showed that the MEyellow module was significantly positively correlated with MAFLD phenotype （cor=0.55， P<0.001）， which was functionally enriched in the efferocytosis pathway. MERTK （P<0.001） and MMP-9 （P<0.001） showed the most significant differential expression in this module. A rat model of MAFLD was successfully established using a high-fat diet， and compared with the control group， the model group had enlarged， yellowish， and greasy liver and disordered structure of hepatic lobules， hepatocyte fatty degeneration， and inflammatory cell infiltration based on HE staining， as well as massive lipid droplet deposition based on oil red O staining， while no obvious fibrous cords were observed in Masson staining. Compared with the control group， the model group had significant increases in the serum levels of aspartate aminotransferase （t=-5.148， P<0.05）， alanine aminotransferase （t=-5.663， P<0.05）， total bilirubin （t=-13.061， P<0.05）， triglyceride （Z=-2.722， P<0.05）， total cholesterol （t=3.588， P<0.05）， and tumor necrosis factor-α （t=-16.741， P<0.05）， as well as significant increases in the protein expression levels of MERTK （t=-11.448， P<0.001） and MMP-9 （t=-10.875， P<0.001） in liver tissue. ConclusionMMP-9 and MERTK are abnormally expressed in MAFLD and may be used as potential diagnostic biomarkers for this disease.

Objective:To analyze the current status and trend of the mortality burden of cardiovascular disease in China from 2010 to 2021.Methods:Data related to cardiovascular disease mortality and disability-adjusted life year (DALY) were extracted from the Global Burden of Disease Study 2021 (GBD2021) database. The age-standardized mortality rate and DALY rate were calculated, using the 2021 world standard population estimated by GBD2021. Joinpoint 5.2.0 software was used to calculate the mortality rate, standardized mortality rate, DALY rate, standardized DALY rate, annual percent change (APC), average annual percent change (AAPC), and 95% CI of cardiovascular disease in China from 2010 to 2021. Results:The mortality rate of cardiovascular disease was 357.44/100 000, and the age-standardized mortality rate was 280.11/100 000 in China in 2021. The DALY rate was 7 043.33/100 000, and the age-standardized DALY rate was 5 120.06/100 000. From 2010 to 2021, the mortality rate and DALY rate of cardiovascular disease in China showed an upward trend (AAPC was 1.58% and 0.83%, respectively, both P<0.05), and the standardized mortality rate and standardized DALY rate showed a downward trend (AAPC was -2.13% and -2.02%, respectively, both P<0.05). The mortality burden of cardiovascular disease was higher in males (mortality rate 392.80/100 000, DALY rate 8 156.19/100 000) than in females (mortality rate 320.38/100 000, DALY rate 5 876.87/100 000). With the increase older in age, the mortality burden of cardiovascular disease in China decreased first and then increased. China ranked high in the mortality burden of cardiovascular disease among G20 member countries. Conclusions:The death burden of cardiovascular disease is serious in China. The mortality rate and DALY rate of cardiovascular disease in China showed an increasing trend from 2010 to 2021, and the standardized mortality rate and standardized DALY rate of cardiovascular disease ranked high in G20 member countries. The death burden of cardiovascular disease was more serious in men and the elderly. It is necessary to develop more comprehensive prevention, treatment, and rehabilitation measures for men and the elderly to reduce mortality and disability rates, decrease the disease burden, and improve the quality of life.
