ObjectiveTo investigate the mechanism of Xiaozhi Qinggan decoction （XQD） in preventing and treating metabolic dysfunction-associated steatotic liver disease （MASLD） by regulating ferroptosis， network pharmacology， in vitro and in vivo experiments. MethodsIn the in vivo experiment， mouse MASLD models were established by high-fat diet （HFD） induction. The model mice were randomly assigned to a positive control group （silybin， 50 mg·kg^-1）， low-， medium- and high-dose XQD groups （4.725， 9.45， 18.9 g·kg^-1）， with a normal control group. After 4 weeks of modeling， mice except the normal group were administered intragastrically for 8 consecutive weeks. Liver function， serum lipid levels， hepatic histopathology， as well as the levels of malondialdehyde （MDA）， superoxide dismutase （SOD）， reduced glutathione （GSH） and oxidized glutathione （GSSG） and Fe²⁺ were detected. The mRNA and protein expression of p53， SLC7A11 and GPX4 were determined by quantitative Real-time quantitative polymerase chain reaction（Real-time PCR） and Western blot. In the network pharmacology analysis， active components and potential targets of XQD for MASLD were screened， followed by functional and pathway enrichment analyses， and molecular docking was performed to verify the target binding activity. In the in vitro experiment， the optimal concentration of XQD-containing serum was screened by cytotoxicity assay. HepG2 cells were transfected with ov-NC or ov-p53 plasmid， and a lipid accumulation model was induced by free fatty acid （FFA， 1.0 mmol·L^-1）. Cells were divided into a normal group， FFA model group， ov-NC+XQD （15%） group and ov-p53+XQD （15%） group. Intracellular Fe²⁺ level and lipid accumulation were evaluated， and the protein expression of p53， SLC7A11 and GPX4 was measured by Western blot. ResultsCompared with the normal group， the model group exhibited markedly elevated body weight， liver weight， liver index， fasting blood glucose， AUC of glucose tolerance test， serum liver function and blood lipid levels at week 12 （P<0.01）. Hepatic steatosis and inflammatory infiltration were observed by pathological staining. Additionally， hepatic levels of MDA， SOD and Fe²⁺ were increased （P<0.01）， while GSH， GSSG and the GSH/GSSG ratio were decreased （P<0.01）. The mRNA and protein expression of hepatic p53 was upregulated （P<0.01）， whereas the expression of SLC7A11 and GPX4 was downregulated （P<0.01）. Compared with the model group， the low- and medium-dose XQD groups showed significantly decreased body weight at week 12 （P<0.05）. The silybin group， together with the medium- and high-dose XQD groups， presented reduced liver weight and liver index （P<0.05）. Fasting blood glucose and the AUC of glucose tolerance test were lowered in all four treatment groups （P<0.05， P<0.01）. Pathological staining revealed alleviated hepatic steatosis and inflammation， accompanied by decreased serum liver function and blood lipid levels （P<0.05， P<0.01）. Moreover， hepatic MDA and SOD levels were markedly reduced， while GSH， GSSG and the GSH/GSSG ratio were significantly elevated （P<0.05， P<0.01）. Hepatic Fe²⁺ level was decreased （P<0.01）. The mRNA and protein expression of hepatic p53 was downregulated， and the expression of SLC7A11 and GPX4 was upregulated （P<0.05， P<0.01）. Network pharmacology analysis identified quercetin， kaempferol， luteolin， tanshinone IIA and isorhamnetin as the core active components of XQD， with p53 serving as the key target. Stable binding was verified between these active components and the p53 protein. The optimal concentration of XQD-containing serum in vitro was determined to be 15%. Compared with the normal group， the model group showed increased intracellular Fe²⁺ and lipid accumulation， significantly upregulated p53 protein expression （P<0.01）， and markedly downregulated SLC7A11 and GPX4 protein expression （P<0.01）. Compared with the model group， the ov-NC group exhibited reduced Fe²⁺ and lipid accumulation， downregulated p53 expression， and upregulated SLC7A11 and GPX4 expression. In the ov-p53 group， p53 expression was upregulated （P<0.01）， while SLC7A11 and GPX4 expression was downregulated （P<0.01）. ConclusionXQD inhibits ferroptosis by downregulating p53 and upregulating SLC7A11 and GPX4， thereby alleviating oxidative stress and lipid peroxidation in hepatocytes and improving MASLD.

LIU Wansu， as the foremost of the four great masters of the Jin-Yuan period， established the "theory of fire-heat'' and extended the fire-heat pathogenesis framework to the field of stroke， thereby forming the theory of ''fire-heat inducing stroke''. This achieved a paradigmatic shift in stroke etiology from ''exogenous wind inducing stroke'' to ''fire-heat inducing stroke''. This paper systematically reviews the developmental trajectory of LIU Wansu's ''fire-heat inducing stroke'' theory and explores the social background， academic origins， and core connotations of its theoretical construction. The study found that， based on the ''Nineteen Pathomechanisms'' in the Huangdi's Internal Classic （Huang Di Nei Jing） and combined with clinical practice， LIU Wansu proposed that fire-heat is the fundamental cause of stroke， and that the Six Climatic Factors and the Five Zhi-Emotions can all transform into fire. He further constructed a stratified syndrome differentiation and therapeutic system centered on clearing heat and purging fire， emphasizing differentiated treatment of exterior and interior syndromes， Six Meridians syndrome differentiation， and seasonally adjusted medication. This theory not only resolved the diagnostic and therapeutic dilemmas of febrile epidemic diseases during the Jin-Yuan period， but also exerted a profound influence on later physicians such as ZHANG Zihe and ZHU Danxi， thereby promoting the pluralistic development of stroke theory in traditional Chinese medicine （TCM）. Modern pharmacological research provides solid scientific evidence， confirming that the ''fire-heat'' pathological state is highly associated with key mechanisms such as excessive inflammatory responses， oxidative stress， and excitatory amino acid toxicity following cerebral ischemia. Heat-clearing and fire-purging prescriptions and agents， such as Huanglian Jiedu Tang and baicalin， can exert multi-target neuroprotective effects by regulating inflammatory signaling， enhancing antioxidant enzyme activity， and balancing neurotransmitters. This not only verifies the scientific basis of the ''fire-heat inducing stroke'' theory from a modern biological perspective but also provides conclusive evidence for the clinical application of heat-clearing and fire-purging therapy. LIU Wansu's ''fire-heat inducing stroke'' theory represents a major milestone in the historical understanding of stroke pathogenesis， and its academically transitional insights continue to hold core guiding value for the pattern identification and treatment of ischemic stroke today.

Objective: To explore human papillomavirus (HPV) and vaccination related knowledge and vaccination willingness of college students in Guizhou Province and their related factors, so as to provide a basis for formulating targeted intervention strategies. Methods: From May to June 2025, by applying convenience sampling method,4 567 college students were selected from 8 universities in Guizhou Province to conduct a questionnaire survey. Awareness of HPV and vaccination related knowledge, vaccination willingness as well as related factors among college students were also analyzed. The t test and Chi square test were used for comparison between groups, and multifactor Logistic regression was employed to analyze the related factors of HPV vaccination willingness among college students. Results: The HPV and vaccine knowledge score of college students in Guizhou Province was ( 10.50 ±2.09), and the score of girls (10.81±1.82) was higher than that of boys (10.19±2.30) ( t=10.09, P <0.01). The HPV vaccination willingness rate of college students was 65.6%, and the rate was higher in girls than in boys (67.1%,64.1%, χ 2=4.75, P <0.05). Multi factor Logistic regression analysis showed that ethnicity and HPV testing were related factors that affected college students willingness to vaccinate (minority: OR boy =1.23, OR girl =1.35; previous HPV testing: OR boy =0.56, OR girl =0.59); boys willingness to vaccinate was related to the number of sexual partners ( OR =0.60), family history of cancer ( OR =0.65), and sexual behavior related HPV knowledge scores ( OR =0.89), while girls willingness to vaccinate was related to bisexual sexual orientation ( OR =0.59), previous HIV testing ( OR =0.60), and HPV and vaccine basic knowledge scores ( OR =0.86) (all P <0.05). Conclusions College students in Guizhou Province have higher HPV vaccine related knowledge scores and are more willing to vaccinate, and those above are higher in girls than in boys. Health education content should be optimized based on gender differences, and promote the willingness and behavior of HPV vaccination among college students.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

ObjectiveTo investigate the influence of empagliflozin combined with donafenib or lenvatinib on the pharmacokinetic parameters of each drug， and to provide a reference for combined medication in clinical practice. MethodsA total of 48 healthy male Sprague-Dawley rats were divided into 8 groups： empagliflozin group 1 and 2， donafenib group， lenvatinib group， donafenib pretreatment+empagliflozin group， lenvatinib pretreatment + empagliflozin group， empagliflozin pretreatment+donafenib group， and empagliflozin pretreatment+lenvatinib group， with 6 rats in each group. The doses of empagliflozin， donafenib， and lenvatinib were 2.5 mg/kg， 40 mg/kg， and 1.2 mg/kg， respectively. The rats in the empagliflozin group， donafenib group， and lenvatinib group were given a blank solvent by gavage for 7 consecutive days， followed by a single dose of empagliflozin， donafenib， or lenvatinib on day 7 after the administration of the blank solvent； the rats in the pretreatment groups were given the pretreatment drug by gavage for 7 consecutive days， followed by a single dose of drug combination on day 7 after administration of the pretreatment drug. Blood samples were collected at different time points， and plasma was separated to measure the concentration of each drug. A validated ultra-performance liquid chromatography-tandem mass spectrometry method was used to measure the plasma concentrations of donafenib， lenvatinib， and empagliflozin， and a non-compartmental model was used to calculate the main pharmacokinetic parameters of each drug （area under the plasma concentration-time curve ［AUC］， time to peak ［T_max］， peak concentration ［C_max］， and half-life time ［t_1/2］）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. ResultsCompared with the empagliflozin group， the donafenib pretreatment+empagliflozin group had significant increases in the AUC_0-t and AUC_0-∞ of empagliflozin （P=0.011 and 0.008）， while the lenvatinib pretreatment+empagliflozin group had no significant change in the AUC of empagliflozin， with a slightly shorter T_max （P=0.019）. Compared with the donafenib group， the empagliflozin pretreatment+donafenib group had significant increases in the AUC_0-t and AUC_0-∞ of donafenib （P=0.027 and 0.025）， as well as a significant increase in C_max （P=0.015） and significant reductions in CLz/F and Vz/F （P=0.005 and 0.004）； compared with the lenvatinib group， the empagliflozin pretreatment+lenvatinib group had a reduction in the t_1/2 of lenvatinib by approximately 5 hours （P=0.002）， with a trend of reduction in AUC_0-t （P0.05）. ConclusionEmpagliflozin combined with donafenib may alter the pharmacokinetic parameters of both drugs， leading to a significant increase in the exposure levels of both drugs， and efficacy and adverse reactions should be monitored during co-administration. There are no significant changes in the exposure levels of empagliflozin and lenvatinib during co-administration.

Objective: To investigate the mediating role of vaccine literacy between vaccine knowledge and vaccine hesitancy and the moderating role of parental education level, so as to provide references for adjusting vaccination strategies. Methods: From May to December 2024, a stratified random sampling method was used to select 10 community hospitals in Guiyang and Zunyi City, Guizhou Province. A total of 1 401 parents of children aged 0-6 years were surveyed regarding their socio demographic characteristics, vaccine knowledge, vaccine literacy, and vaccine hesitancy levels. Data were analyzed using common method bias tests, Spearman correlation analysis, mediation and moderation effects tests. Results: The mean score for vaccine knowledge, vaccine literacy and vaccine hesitancy were (2.96±1.11, 14.25±2.64, 39.12±4.93) among the 1 401 participants. Mediating effect analysis showed that both parental vaccine knowledge ( β =1.28, 95% CI =1.08-1.49) and vaccine literacy ( β =0.75, 95% CI =0.66-0.84) positively predicted vaccine hesitancy (both P <0.01). Meanwhile, vaccine literacy accounted for 28.1% of the total effect of mediation between knowledge and vaccine hesitancy. In the moderated effects analysis, education level positively predicted vaccine literacy ( β =0.40, 95% CI =0.24-0.57), and education level moderated the pathway of vaccine knowledge on vaccine hesitancy ( β = 0.28 , 95% CI =0.05-0.52) (both P <0.01). Conclusions Vaccine literacy partially mediates the relationship between vaccine knowledge and vaccine hesitancy. Parental education level positively moderates the prediction of vaccine knowledge on vaccine hesitancy score.

This paper reviews the published articles of recent years on the application of deep learning methods in automatic localization of acupoint, and summarizes it from 3 key links, i.e. the dataset construction, the neural network model design, and the accuracy evaluation of acupoint localization. The significant progress has been obtained in the field of deep learning for acupoint localization, but the scale of acupoint detection needs to be expanded and the precision, the generalization ability, and the real-time performance of the model be advanced. The future research should focus on the support of standardized datasets, and the integration of 3D modeling and multimodal data fusion, so as to increase the accuracy and strengthen the personalization of acupoint localization.
