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.

OBJECTIVE To quantitatively assess the compatibility risk of commonly used intravenous drugs in intensive care unit (ICU) patients with severe pneumonia, and provide a reference for reducing the incidence of adverse events caused by incompatibility. METHODS The PASS clinical pharmacy management system was used to retrospectively collect the data of patients diagnosed with “severe pneumonia” in the ICU of Hebei General Hospital from January 2023 to June 2025, and the commonly used intravenous drugs and medication frequency were extracted. Based on authoritative databases such as Micromedex and Stabilis as well as relevant literature, the compatibility data of commonly used intravenous drugs with 0.9% Sodium chloride injection and 5% Glucose injection were summarized. The theoretical and actual compatibility risk values were calculated using formulas, and high-risk drugs were screened and the compatibility query table was drawn. RESULTS A total of 158 ICU patients with severe pneumonia were treated with 89 intravenous drugs, and 24 drugs with high compatibility risk were identified. The drug with the highest theoretical compatibility risk value was Amphotericin B for injection (risk value 146), and the drug with the highest actual compatibility risk value was Propofol medium and long chain fat emulsion injection (risk value 8 740). Among the 24 high-risk drugs, six drugs, namely Esomeprazole sodium for injection, Ambroxol hydrochloride injection, Midazolam injection, Methylprednisolone sodium succinate for injection, Furosemide injection, and Cefoperazone sodium and sulbactam sodium for injection, simultaneously ranked among the top 15 in both theoretical and actual compatibility risk rankings. Among 650 pairwise compatibility combinations of the 24 drugs, 24.62% were compatible, 11.23% were incompatible, 6.77% had conflicting evidence, and 57.38% had missing evidence. CONCLUSIONS This study quantitatively analyzed the medication safety of commonly used intravenous drugs in ICU patients with severe pneumonia, identified 24 drugs with high compatibility risk, and established a compatibility query table for high-risk drugs, which helps reduce the risk of ICU compatibility adverse events.

Objective To explore the biomechanical difference between bilateral pedicle screws fixation and unilateral pedicle screw combined with contralateral translaminar facet screw fixation under two endo-scopic approaches(interlaminar approach and transforaminal approach)through finite element analysis.Meth-ods The fusion model of simple fusion device(CAGEF model),interlaminar approach and transforaminal ap-proach models for bilateral pedicle screw fixation(BPSP model and BPSL model),and interlaminar approach and transforaminal approach for unilateral pedicle screw fixation combined with contralateral translaminar fac-et screw fixation(TLFSP model and TLFSL model)were established.The peak value of spinal displacement,maximum stress of the intervertebral fusion device,maximum stress of the internal fixation device,and maxi-mum stress of the L3 and L4 intervertebral disc of each model under six motion states:forward flexion,back-ward extension,left/right flexion,and left/right rotation were compared among the models.Results Com-pared with the CAGEF model,the peak spinal displacement and the maximum stress of the interbody fusion cage in the other four models were significantly reduced,and the values of the four fixed models were close to each other.The maximum stress of the internal fixation device in the three motion states of left flexion,left rotation,and right rotation in the BPSP model was greater than that in the BPSL model,while the maximum stress of the internal fixation device in TLFSP model was less than that in the TLFSL model only under the forward flexion motion state.Compared with the TLFSP model and TLFSL model,the maximum stress of the internal fixation devices in the BPSP model and BPSL model was greater only in the two motion states of flex-ion and extension,while which in the other four cases was smaller.Except for the maximum stress on the L3 and L4 intervertebral disc during rotation in the CAGEF model was higher than the other 4 models,the maxi-mum stress on the L3 and L4 intervertebral disc was similar in all other models under other motion states.Conclusion Under both interlaminar and foraminal approaches,the bilateral pedicle screws fixation and uni-lateral pedicle screw combined with contralateral translaminar facet screw fixation are both effective minimally invasive spinal fusion operations,and their biomechanical conditions are satisfactory.If choosing the interlami-nar approach,it is recommended to perform bilateral pedicle screw fixation,meanwhile decreasing the forward flexion and backward extension movements.Alternatively,a unilateral pedicle screw combined with contralat-eral interlaminar screw fixation can also be considered,while reducing left/right flexion movements.Howev-er,the specific treatment choice still needs to consider the patient's personalized treatment and the surgical operation ability of the clinical physician.
