This study establishes an integrated research paradigm based on traditional Chinese medicine （TCM） theory， guided by pathological characteristics， centered on formula compatibility principles， and supported by multidisciplinary technologies， to systematically analyze the mechanisms of hepatotoxicity induced by toxic Chinese herbal medicinals and strategies for reducing toxicity through compatibility. The findings revealed that the pathomechanism aligns closely with the "liver aversion to acute irritation" theory from Inner Canon of Yellow Emperor （《黄帝内经》）. The core pathology involves an imbalance between liver's form and function， which is characterized by malnourishment of liver form due to yin-blood depletion and dysfunction in ascending-dispersing and free-flowing activities， and closely linked to modern pathological mechanisms such as microcirculatory disturbances， oxidative stress， inflammatory response， metabolic disorder and gut-liver axis dysregulation. Based on this， a multi-layered compatibility strategy for toxicity reduction is put forward， which involves using sweet medicinals to alleviate urgency， balancing the liver form and its function， and pre-regulating other organs. This provides a theoretical basis for the safe application of toxic Chinese herbal medicinals.

Given the limitations of traditional scientific research methods in revealing the complex and dynamic evolution of disease pathomechanisms， this paper analyzes the current state and challenges of the traditional Chinese medicine （TCM） pathomechanism syndrome differentiation system within the framework of systems thinking. The challenges include insufficient experimental models， low data standardization， complex nonlinear characteristics， and difficulties in integrating expert experience. By leveraging qualitative-quantitative comprehensive integration methods， this paper proposes specific research strategies， including constructing qualitative models of pathomechanism evolution， employing mathematical models for validation and quantitative analysis to reveal pathomechanism patterns， and incorporating a "human-centered" approach to achieve human-machine collaboration. These strategies aim to provide insights for the modernization and development of a new TCM pathomechanism syndrome differentiation system.

ObjectiveTo observe the clinical efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia. MethodsIn this study， hyperlipidemia patients treated in the Hospital of Chengdu University of Traditional Chinese Medicine （TCM） from September 2022 to December 2023 were randomly assigned into a control group and an observation group. Finally， 162 valid cases were included， encompassing 74 cases in the control group and 88 cases in the observation group. The control group was treated with atorvastatin calcium tablets， and the observation group with atorvastatin calcium tablets + Zhuyuwan extract granules. Both groups were treated for 8 weeks. The efficacy in terms of blood lipid level recovery， blood lipid levels， TCM syndrome distribution， efficacy in terms of TCM syndrome， and TCM symptom scores were compared between the two groups as well as between before and after treatment. Liver and kidney functions were monitored for safety assessment. ResultsIn terms of blood lipid level recovery， the total response rate in the observation group was 86.36% （76/88） and that in the control group was 86.49% （64/74）， with no statistically significant difference between the two groups. After treatment， both groups showed declines in levels of triglyceride （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C） （P<0.05） and elevations in the level of high-density lipoprotein cholesterol （HDL-C） （P<0.05）. Moreover， the observation group outperformed the control group in recovering the levels of TG， LDL-C， and HDL-C （P<0.05， P<0.01）. In terms of TCM syndrome， hyperlipidemia was mostly caused by phlegm turbidity and obstruction. The total response rate in terms of TCM syndrome in the observation group was 87.30% （55/63）， which was higher than that （63.46%， 33/52） in the control group （χ²=9.102， P<0.01）. After treatment， the scores of total TCM symptoms， primary symptoms， and secondary symptoms decreased in both groups （P<0.05）， and the observation group had lower scores than the control group （P<0.01）. The observation group was superior to the control group in alleviating obesity， chest tightness， and low food intake （P<0.05）. In terms of safety， the level of aminotransferase was slightly elevated in the control group， and no obvious adverse reaction was observed in the observation group， with no statistical significance in the incidence of adverse reactions. ConclusionZhuyuwan combined with atorvastatin can not only recover blood lipid levels and alleviate TCM symptoms but also reduce the occurrence of adverse reactions.

Objective:To discuss the optimal doping concentration of vanadium(V)and silicon(Si)co-doped TiO? coating(V-Si TiO?)formed on titanium surface by electrochemical treatment,to evaluate its antibacterial effect under visible light irradiation,and to clarify its visible light response mechanism.Methods:The medical pure titanium sheets were subjected to micro-arc oxidation followed by high-temperature calcination,and V-Si TiO2 coatings with different doping concentrations were prepared by adjusting the ratio of V to Si in the electrolyte.The experiment was divided into 1V:10Si(V5Si50)group,2V:10Si(V10Si50)group,and 3V:10Si(V15Si50)group;control group was set up(contains only bacterial culture medium).The optimal doping concentration was screened based on comprehensive evaluation of surface morphology,ion release,photocatalytic ability,and biocompatibility;cell counting kit-8(CCK-8)method was used to detect the proliferation activities and the survival rates of the cells in various group.Subsequently,the optimized coating was characterized and compared by scanning electron microscope(SEM),atomic force microscopy(AFM),digital eddy current coating thickness gauge,X-ray diffraction(XRD),X-ray photoelectron spectroscope(XPS),and ultraviolet-visible absorption spectroscopy(UV-vis).The experiment was divided into PT group(blank control),PEO group(no element doping),V10 group(V doping),Si50 group(Si doping),and V10Si50 group(2V:10Si).The ability of the coating materials to degrade methylene blue(MB)and generation of reactive oxygen species(ROS)under visible light were detected.For antibacterial experiments,Staphylococcus aureus(S.aureus)and Escherichia coli(E.coli)were used.The colony counts on plates in various groups were recorded after visible light irradiation for 2 h and dark treatment for 2 h,respectively.The ROS levels were detected using 2',7'-dichlorofluorescein diacetate(DCFH-DA)ROS probe.ROS scavenging experiment was performed using the optimal doping concentration V10Si50 group,and the two kinds of bacteria were divided into blank control group,N-acetylcysteine(NAC)group,V10Si50 group,and NAC+V10Si50 group.The colony counts on plates in various groups were recorded after visible light irradiation for 2 h.Results:The V concentration of 0.01 mol·L?1 and Si concentration of 0.05 mol·L?1 in the electrolyte solution were the optimal doping concentrations for the V-Si TiO? coating.The SEM observation results showed that compared with V5Si50 group and V15Si50 group,the surface pore size of the coating material in V10Si50 group was significantly decreased(P<0.05),and the coating thickness was significantly increased(P<0.05);its crystal structure was mainly anatase type,and the MB degradation rate of the coating material in V10Si50 group after 9 h of visible light catalysis was significantly increased(P<0.05).Compared with control group,the cell proliferation activity and cell survival rate in V10Si50 group were significantly increased at 1,2,and 4 d of cell culture(P<0.05);at 2 and 4 d of cell culture,the cell proliferation activity and cell survival rate in V5Si50 group and V15Si50 group were significantly decreased(P<0.05).Compared with PT,PEO,and Si50 groups,the colony counts of two kinds of the bacteria in V10 group and V10Si50 group after visible light irradiation for 2 h were significantly decreased(P<0.05).Compared with PT group and PEO group,the ROS levels in two kinds of the bacteria in V10Si50 group after 2 h of irradiation were significantly increased(P<0.05).Compared with V10Si50 group,the colony counts of two kinds of the bacteria in NAC+V10Si50 group were significantly increased(P<0.05).Conclusion:A reasonably loaded V-Si TiO? coating material(V10Si50)was screened out,which maintained good biological activity and significantly enhanced the antibacterial effect under visible light irradiation.

OBJECTIVES: To investigate the protective effect of catalpol against triptolide-induced liver injury and explore its mechanism to test the Fuzheng Zhidu theory for detoxification. METHODS: C57BL/6J mice were randomized into blank control group, catalpol group, triptolide group and triptolide+catalpol group. After 13 days of treatment with the agents by gavage, the mice were examined for liver tissue pathology, liver function, hepatocyte subcellular structure, lipid peroxidation, ferrous ion deposition and expressions of ferroptosis-related proteins in the liver. In a liver cell line HL7702, the effect of catalpol or the ferroptosis inhibitor Fer-1 on triptolide-induced cytotoxicity was tested by examining cell functions, Fe²⁺ concentration, lipid peroxidation, ROS level and the ferroptosis-related proteins. RESULTS: In C57BL/6J mice, catalpol significantly alleviated triptolide-induced hepatic injury, lowered the levels of ALT, AST and LDH, and reversed the elevation of Fe²⁺ concentration and MDA level and the reduction of GP_X level. In HL7702 cells, inhibition of ferroptosis by Fer-1 significantly reversed triptolide-induced elevation of ALT, AST and LDH levels. Western blotting and qRT-PCR demonstrated that catalpol reversed abnormalities in expressions of SLC7A11, FTH1 and GPX4 at both the mRNA and protein levels in triptolide-treated HL7702 cells. CONCLUSIONS The combined use of catalpol can reduce the hepatotoxicity of triptolide in mice by inhibiting excessive hepatocyte ferroptosis through the SLC7A11/GPX4 pathway.

Objective:To investigate the influence of different sensory learning style preferences of officers and soldiers on satisfaction with military continuing education online courses, understand their diversified and personalized learning needs, and provide a reference for online course construction.Methods:VARK (Visual, Aural, Read/Write, Kinesthetic) questionnaire and a self-designed satisfaction questionnaire were distributed to naval officers and soldiers who participated in online courses of military continuing education. Of the 10 000 questionnaires distributed, 8 124 (81.24%) valid responses were collected. SPSS 22.0 was used for statistical analysis. The satisfaction was expressed by ( x± s). The satisfaction of participants with different sensory learning style types, tendency multiplicity, intensity, and distribution was compared using analysis of variance. Pairwise comparisons for significant differences were conducted using the Student-Newman-Keuls test at a significance level of 0.05. Results:①Significant differences were observed in the satisfaction of officers and soldiers with different types of sensory learning styles on the 14 aspects of military continuing education online courses ( F=3.41, 3.33, 1.82, 2.22, 1.84, 2.67, 2.37, 2.27, 2.68, 2.20, 2.61, 3.37, 2.86, and 2.38; all P<0.05), and the satisfaction with each aspect was in the same column. ②Significant differences were observed in the satisfaction of officers and soldiers with different tendency multiplicity in the 14 aspects of military continuing education online courses ( F=12.21, 11.92, 6.15, 6.14, 5.85, 8.29, 7.47, 8.62, 9.10, 6.51, 8.81, 12.18, 9.27, and 9.00; all P<0.05), and the officers and soldiers with quadruple styles showed relatively high satisfaction. ③Significant differences were observed in the satisfaction of officers and soldiers with different intensities of sensory learning styles in the 12 aspects of military continuing education online courses ( F=4.18, 5.27, 3.06, 2.76, 3.54, 4.23, 4.68, 2.95, 4.85, 7.66, 5.75, and 2.69; all P<0.05), except for the 2 aspects of job promotion courses as well as the richness, scientificity, novelty, and refinement of course content ( F=1.68 and 1.79; P=0.169 and 0.147). ④Significant differences were observed in the satisfaction of officers and soldiers with different distribution of sensory learning styles in the 12 aspects of military continuing education online courses ( F=4.33, 5.16, 4.57, 2.84, 3.51, 3.70, 4.24, 2.71, 4.29, 6.07, 5.19, and 2.47; all P<0.05), except for the 2 aspects of job promotion courses as well as the richness, scientificity, novelty, and refinement of course content ( F=1.61 and 2.35, P=0.168 and 0.052). Conclusions:The satisfaction with military continuing education online courses was influenced by the sensory preferences of learners, and the satisfaction of officers and soldiers with multiple styles was relatively high. The overall satisfaction of officers and soldiers was generally high, but special attention should be paid to groups with low satisfaction. The advantage of personalized teaching in online education should be utilized and multiple measures should be taken to improve the quality of online education.

Objective:To construct a machine learning model based on serum indicators and lung ultrasound features for the prediction of respiratory failure in children with severe pneumonia.Methods:Case-control study.The clinical data of 208 children with severe pneumonia admitted to the Pediatric Intensive Care Unit of Jiujiang Maternal and Child Health Hospital from January 2019 to January 2024 were analyzed.According to whether respiratory failure occurred 3 months after admission, the patients were divided into a respiratory failure group (131 cases) and a non-respiratory failure group (77 cases).Logistic regression, classification regression tree (CRT) and back propagation neural network (BPNN) algorithms based on machine learning were used to construct the prediction models of respiratory failure in children with severe pneumonia by SPSS software.The predictive value of models was analyzed by the receiver operating characteristic (ROC) curve.Results:The univariate analysis showed that there were significant differences in age, history of pulmonary infection, pediatric critical illness score (PCIS), congenital airway malformation, congenital heart disease, lung ultrasound score (LUS), Krebs von den Lungen-6 (KL-6) and soluble triggering receptor expressed on myeloid cells 1 (sTREM-1) between the two groups (all P<0.05).The multivariate Logistic regression analysis showed that age, PCIS score, LUS, congenital heart disease, KL-6 and sTREM-1 were independent risk factors for respiratory failure in children with severe pneumonia (all P<0.05).The analysis results of the CRT model showed that age, congenital heart disease, KL-6 and congenital airway malformation were factors influencing the development of respiratory failure in children with severe pneumonia.The analysis results of the BPNN model indicated that KL-6 was the most important factor that affected the occurrence of respiratory failure in severe pneumonia, followed by age, sTREM-1, LUS, PCIS score, congenital heart disease, congenital airway malformation, and history of pulmonary infection successively.Among the models constructed by the three machine learning algorithms, the Logistic model had the best prediction performance, with an area under the ROC curve of 0.981, a sensitivity of 0.962, and a specificity of 0.909. Conclusions:The risk factors of respiratory failure in children with severe pneumonia include age, LUS, KL-6, sTREM-1, etc.Machine learning models based on serum indicators and lung ultrasound features are effective in predicting respiratory failure in children with severe pneumonia, especially the Logistic model, which has the best prediction efficiency.
