OBJECTIVE To explore a new model of intelligent medication education for pharmaceutical outpatient clinics by constructing dynamic HTML web pages through the DeepSeek-V3-0324 large-scale model. METHODS Clinical pharmacists integrated key clinical information such as patients’ basic information， medication history and medication precautions in real time， and generated a standardized medication education list through the DeepSeek-V3-0324 large-scale model and manual review. RESULTS The DeepSeek-V3-0324 large-scale model was applied in the pharmaceutical outpatient clinics to generate a personalized medication education list， which could effectively solve the disunity of pharmacy guidance caused by the lack of standardization of medication education and the difference of individualized experience of pharmacists in the traditional pharmaceutical outpatient clinics in the face of complex cases， and medication errors caused by forgetting or misremembering information among certain special patient populations after receiving medication education. CONCLUSIONS The transformation and application of artificial intelligence technology in pharmaceutical outpatient clinics is an innovation of pharmaceutical outpatient service means， which can provide patients with immediate and personalized medication education and improve the quality of pharmaceutical care. However， it is also necessary to face the lag of database update and the lack of risk management， as well as the lack of diversification of medication education lists.

Ferroptosis, a programmed cell death modality discovered and defined in the last decade, is primarily induced by iron-dependent lipid peroxidation. At present, it has been found that ferroptosis is involved in various physiological functions such as immune regulation, growth and development, aging, and tumor suppression. Especially its role in tumor biology has attracted extensive attention and research. Breast cancer is one of the most common female tumors, characterized by high heterogeneity and complex genetic background. Triple negative breast cancer (TNBC) is a special type of breast cancer, which lacks conventional breast cancer treatment targets and is prone to drug resistance to existing chemotherapy drugs and has a low cure rate after progression and metastasis. There is an urgent need to find new targets or develop new drugs. With the increase of studies on promoting ferroptosis in breast cancer, it has gradually attracted attention as a treatment strategy for breast cancer. Some studies have found that certain compounds and natural products can act on TNBC, promote their ferroptosis, inhibit cancer cells proliferation, enhance sensitivity to radiotherapy, and improve resistance to chemotherapy drugs. To promote the study of ferroptosis in TNBC, this article summarized and reviewed the compounds and natural products that induce ferroptosis in TNBC and their mechanisms of action. We started with the exploration of the pathways of ferroptosis, with particular attention to the System X_c^--cystine-GPX4 pathway and iron metabolism. Then, a series of compounds, including sulfasalazine (SAS), metformin, and statins, were described in terms of how they interact with cells to deplete glutathione (GSH), thereby inhibiting the activity of glutathione peroxidase 4 (GPX4) and preventing the production of lipid peroxidases. The disruption of the cellular defense against oxidative stress ultimately results in the death of TNBC cells. We have also our focus to the realm of natural products, exploring the therapeutic potential of traditional Chinese medicine extracts for TNBC. These herbal extracts exhibit multi-target effects and good safety, and have shown promising capabilities in inducing ferroptosis in TNBC cells. We believe that further exploration and characterization of these natural compounds could lead to the development of a new generation of cancer therapeutics. In addition to traditional chemotherapy, we discussed the role of drug delivery systems in enhancing the efficacy and reducing the toxicity of ferroptosis inducers. Nanoparticles such as exosomes and metal-organic frameworks (MOFs) can improve the solubility and bioavailability of these compounds, thereby expanding their therapeutic potential while minimizing systemic side effects. Although preclinical data on ferroptosis inducers are relatively robust, their translation into clinical practice remains in its early stages. We also emphasize the urgent need for more in-depth and comprehensive research to understand the complex mechanisms of ferroptosis in TNBC. This is crucial for the rational design and development of clinical trials, as well as for leveraging ferroptosis to improve patient outcomes. Hoping the above summarize and review could provide references for the research and development of lead compounds for the treatment for TNBC.

ObjectiveTo investigate the mechanism of danshenol A （DA） pretreatment in alleviating myocardial ischemia-reperfusion injury （MIRI） by regulating cardiomyocyte ferroptosis by in vivo and in vitro experiments. MethodsA MIRI model was established in SD rats， and an in vitro oxygen-glucose deprivation/reoxygenation （OGD/R） model was constructed with H9C2 cells. Both models were treated with DA. H9C2 cells were allocated into blank， model （OGD/R）， DA， ferroptosis inducer （erastin）， and ferroptosis inhibitor （Fer-1） groups. Cell viability was assessed by the methyl thiazolyl tetrazolium （MTT） assay. Biochemical assays were performed to measure the superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione （GSH）， and ferrous ion （Fe²⁺） levels. Dihydroethidium （DHE） fluorescence assay was adopted to quantify the reactive oxygen species （ROS） level. Real-time PCR and Western blot were employed to quantify the mRNA and protein levels， respectively， of prostaglandin-endoperoxide synthase 2 （PTGS2）， glutathione peroxidase 4 （GPX4）， ferritin heavy chain 1 （FTH1）， and acyl-coA synthetase long-chain family 4 （ACSL4）. Sixty SPF-grade healthy male SD rats were randomly assigned to control， model （MIRI）， DA， erastin， and Fer-1 groups. Enzyme-linked immunosorbent assay （ELISA） was adopted to measure the serum levels of cardiac troponin I （cTnI）， lactate dehydrogenase （LDH）， and creatine kinase （CK）. Histopathological changes in the myocardial tissue were observed by hematoxylin-eosin （HE） staining. Cardiomyocyte apoptosis was detected by terminal deoxynucleotidyl transferase-mediated nick end labeling （TUNEL）. The effect of DA on cardiomyocyte ferroptosis were observed and analyzed by in vivo and in vitro experiments. ResultsIn vitro experiment： compared with the blank group， the OGD/R model group showed reduced cell viability， elevated levels of ROS， MDA， and Fe²⁺， up-regulated mRNA and protein levels of ACSL4， lowered levels of SOD and GSH， and down-regulated mRNA and protein levels of PTGS2， GPX4， and FTH1 （P<0.05，P<0.01）. The DA and Fer-1 groups exhibited consistent trends： cell viability， SOD and GSH levels， and the mRNA and protein levels of PTGS2， GPX4， and FTH1 were significantly restored， while the ROS， MDA， and Fe²⁺ levels， and the mRNA and protein levels of ACSL4 were reduced （P<0.05，P<0.01）. In vivo experiment： Compared with the control group， the MIRI model group showed elevated serum levels of cTnI， LDH， and CK， increased cardiomyocyte apoptosis rate， risen levels of ROS， MDA， and Fe²⁺， and up-regulated mRNA and protein levels of ACSL4. However， both DA and Fer-1 groups exhibited reductions in the indicators above （P<0.05）. Compared with the control group， the MIRI model group demonstrated reduced levels of SOD and GSH and down-regulated mRNA and protein levels of PTGS2， GPX4， and FTH1 （P<0.05）. In contrast， both DA and Fer-1 upregulated these indicators （P<0.05）， effectively reversing the trends in the model group. In addition， the MIRI model group showed swelling of cardiomyocytes， disarrangement of cardiac muscle fibers， and massive inflammatory cell infiltration， which were alleviated in the DA and Fer-1 groups. ConclusionDA alleviates MIRI by inhibiting ferroptosis and inflammation， demonstrating therapeutic potential in acute myocardial infarction.

Bongkrekic acid(BA)is a toxin with stable properties and no distinctive smell.It exists in common foods such as fermented edible grain products,potato products,spoiled tremella fuciformis and auricularia polytricha,as well as auricularia polytricha that has been soaked too long.It can easily cause food poisoning.At present,there is still a lack of complete method to detect BA,and no spe-cific antidote of BA has been found.Therefore,BA poisoning is easy to be misdiagnosed or missed diagnosed,and its mortality rate remains high.In recent years,studies have revealed the toxic mecha-nism of BA and found that BA can inactivate some enzymes containing thiol groups(-SH)and in-hibit the synthesis and transport of adenosine triphosphate(ATP),causing damage to liver,kidney,brain and other parenchymal organs.This article reviews the autopsy cases and literature of deaths caused by BA poisoning at home and abroad,systematically summarizes the epidemiology,clinical manifestations,pathological changes,toxicological mechanisms,detection methods,forensic diagnostic key points and challenges of BA in forensic medicine,with the aim of providing a reference for foren-sic identification of related cases.

Objective To analyze the differences in bone serum protein between patients with osteoporosis accompanied by obstructive sleep apnea syndrome(OSAS)and those with osteoporosis only using proteomics.Methods A total of 80 osteoporosis patients who attended our hospital between June 2022 and June 2024 were enrolled.Based on their polysomnography results,the participants were divided into an OSAS and osteoporosis comorbidity(OSAS-osteoporosis)group(n=42)and an osteoporosis only group(n=38).Propensity score matching was applied to incorporate covariates in logistic regression so that the individual characteristics of the two groups of patients were generally balanced.Following the matching procedure,a final cohort of 20 matched pairs was obtained and subsequently utilized for further analysis.The mass spectrum was obtained using laser desorption ionization mass spectrometry.Principal component analysis(PCA)was performed to assess differences in metabolic patterns between groups.Partial least squares discriminant analysis(PLS-DA)and orthogonal PLS-DA(OPLS-DA)were employed for further data analysis.Variable importance in projection(VIP)scores of each substance were calculated with OPLS-DA to screen the metabolites showing inter-group differences.Heatmaps were generated to visualize metabolic profile differences between the OSAS-osteoporosis group and the osteoporosis group.Enrichment pathway analysis was conducted on the differential identified metabolites.Results After propensity score matching,individual characteristics between the groups were well balanced.Mass spectrometry revealed significant differences between the OSAS-osteoporosis and osteoporosis groups.In the PCA score plot,the separation trend of the two groups was not significant.The PLS-DA score plot showed a discernible separation trend,with R2 and Q2 lower than those of the corresponding results of the real model,confirming the reliability of the model.OPLS-DA showed that the total R2X of the model was 0.635,R2Y was 0.879,and O2Y was 0.728,showing obvious separation trends between the two groups.A total of 16 differential metabolites were identified,including stearyl-oleyl-glycerol phosphate choline,phosphate choline,L-histidine,erucamide,2'-deoxyuridine,1-palmitoyl glycerol,thymine,tyramine,L-pyroglutamic acid,L-glutamic acid,myristate,glycerol-3-phosphate,caprylic acid,pregnenolone,L-arginine,D-4-hydroxyphenylglycine,and isobutyric acid.Heatmaps showed significant differences in metabolic profiles between the OSAS-osteoporosis group and the osteoporosis group.Pathway enrichment analysis showed that 27 metabolic pathways were involved.27 metabolic pathways.Under the conditions of P<0.05 and pathway impact>0.2,the three most significant metabolic pathways identified included mainly alanine,aspartate,and glutamate metabolism,arginine biosynthesis,and histidine metabolism.Conclusion Significant differences were observed in the metabolic profiles between patients with both OSAS and osteoporosis and those with osteoporosis alone.

OBJECTIVE To investigate the effects of potassium channel Kv1.3knockout(Kv1.3 KO)on neurological dysfunction and neuroinflammation in C57BL/6 mice following traumatic brain injury(TBI).METHODS C57BL/6 mice and homozygous Kv1.3 KO C57BL/6 mice were subjected to the classic controlled cortical impact model to establish a TBI model.The experimental groups included the sham surgery group,C57BL/6 TBI model group(TBI group),and a Kv1.3 KO C57BL/6 TBI model group(TBI+Kv1.3 KO group).At 1,2,and 3 weeks post-modeling,real-time quantitative PCR was used to measure the mRNA expression levels of Kv1.3,interleukin-1β(IL-1β),IL-6,tumor necrosis factor-α(TNF-α),and IL-10 in hippocampal tissues.At 1 and 3 weeks post-modeling,Western blotting was performed to detect Kv1.3 protein expressions in the hippocampus.At 3 weeks post-modeling,Western blotting was used to assess the protein levels of IL-1β,IL-6,TNF-α,and IL-10 in hippocampal tissues.Additionally,immunofluorescence was employed to quantify cells co-labeled with the microglial marker ionized calcium-binding adapter molecule 1(IBA1)and Kv1.3,IL-1β,or TNF-α in the hippocampus.Patch-clamp recordings were conducted to measure Kv1.3 channel currents in primary microglia at 3 weeks post-modeling.Neurological function was evaluated at 1 and 3 weeks post-modeling using the neurological severity score(NSS),pole climbing,and rotarod tests.Cognitive function was assessed at 3 weeks post-modeling via open field,Morris water maze,and Y-maze tests.RESULTS Compared with the sham group,the TBI group exhibited significantly elevated mRNA expression levels of Kv1.3 and IL-1β in the hippocampus at 1,2 and 3 weeks post-modeling,while IL-6 and IL-10 mRNA levels showed no significant changes.Notably,TNF-α mRNA expressions demonstrated a significant increase only at 2 and 3 weeks post-modeling.At 1 and 3 weeks post-modeling,Kv1.3 protein expres-sions in the hippocampus were significantly higher in the TBI group.At 3 weeks post-modeling,hippo-campal IL-1β and TNF-α protein levels were markedly increased in the TBI group,whereas IL-6 and IL-10 protein levels did not change significantly.Moreover,Kv1.3 current density in primary microglia was signifi-cantly enhanced in the TBI group at 3 weeks post-modeling.Immunofluorescence analysis revealed that the number of IBA1-positive microglia co-labeled with Kv1.3,IL-1β,or TNF-α in the hippocampus was significantly larger in the TBI group than in the sham group at 3 weeks post-modeling.Behaviorally,the TBI group exhibited significantly higher NSS scores,lower success rates in full turn attempts,and longer times taken to descend the pole at 1 and 3 weeks post-modeling compared with the sham group.At 3 weeks post-modeling,TBI mice also demonstrated reduced total movement distance in the open field,decreased time spent in the central zone,fewer platform crossings,less time in the target quadrant,and lower spontaneous alternation rates.In contrast,the TBI+Kv1.3 KO group showed signifi-cantly improved outcomes compared with the TBI group:lower NSS scores,higher success rates in full turns,and shorter time taken to descend the pole at 1 and 3 weeks post-modeling.At 3 weeks post-modeling,the TBI+Kv1.3 KO group displayed longer rotarod endurance,increased total movement dis-tance in the open field,more time spent in the central zone,higher platform crossings,greater target quadrant exploration time,and improved spontaneous alternation rates.Furthermore,at 1 and 3 weeks post-modeling,the TBI+Kv1.3 KO group exhibited significantly reduced mRNA expression levels of the inflammatory cytokines IL-1β and TNF-α in the hippocampus compared with the TBI group.CONCLU-SION Potassium channel Kv1.3 knockout mitigates neurological dysfunction and neuroinflammation in C57BL/6 mice following TBI.

Objective To understand the current status of work-related musculoskeletal disorders (WMSDs) among operating room doctors,thereby analyzing its effect on mental health. Methods A total of 1013 doctors in the operating rooms of 30 hospitals in 24 provinces from September to December 2022 were selected by cross-sectional survey method. The domestic musculoskeletal disease questionnaire was used to investigate the occurrence of WMSDs in operating room doctors,the symptom check list-90 (SCL-90) was used to evaluate the psychological status of operating room doctors,the relationship between WMSDs related items and SCL-90 scores was analyzed,the correla-tion between the rest time of each shift and SCL-90 factors was analyzed by Pearson method,and the influencing factors of mental health of operating room doctors were analyzed by multivariate Logistic regression.Results A total of 1100 questionnaires were distributed and 1013 valid questionnaires were recovered,with an effective rate of 92.10％. The incidence of WMSDs among operating room doctors in the past 1 year was 95.06％. The body parts with incidences of WMSDs from high to low were as follows:waist (36.92％),neck (35.54％),shoulder (33.56％),and upper back (32.77％). In the past 1 year,the SCL-90 scores and total scores of patients with musculoskeletal pain in various body parts,keeping the same back posture for a long time while work,bending the back at the same time of turning frequently while working,bowing the head for a long time while working,and bending the knee for a long time while working were significantly higher than those who were without the above conditions (P<0.05). Shorter rest time of each shift and longer periods of keeping the same back posture were the risk factors for the development of mental illness in operating room doctors. Conclusion The incidence of WMSDs in operating room doctors is high,which can influence the mental health of operating room doctors. Therefore,operating room doctors should avoid keeping the same back posture for a long time,bending the back at the same time of turning frequently,bowing the head for a long time,and bending the knee for a long time while working,and increase the rest time of each shift,in order to improve the mental condition of the operating room doctors.

Objective:To design a vest-type breast dressing bra and explore its application effect in the external application of traditional Chinese medicine therapy for patients with granulomatous lobular mastitis(GLM).Methods:A randomized controlled study was conducted, utilizing convenience sampling to select female patients with 122 GLM who underwent their first topical medication treatment in the Breast Department of Guangdong Provincial Hospital of Traditional Chinese Medicine between January and May 2023. The patients were divided into a control group and an observation group, with 61 patients in each, using a random number table. Following medication application, patients in the control group used a regular sports bra to secure the medication, while patients in the observation group used a custom-designed vest-style breast medication bra for the same purpose. Three hours after the intervention, comparisons were made between the two groups in terms of the incidence of medication detachment, medication displacement, clothing contamination, patient satisfaction, and safety.Results:Both groups of patients completed the study. The age of the observation group was (32.18 ± 5.50) years old, while the age of the control group was (33.66 ± 5.20) years old. Three hours after the intervention, the incidence of medication detachment, medication displacement, clothing contamination in the observation group were 3.28% (2/61), 6.56% (4/61), and 8.20% (5/61), which were lower than those in the control group with 18.03% (11/61), 26.23% (16/61), and 67.21% (41/61), respectively. The differences were statistically significant ( χ2=6.97, 8.61, 45.23; all P<0.05). The satisfaction level of patients towards the bra in the observation group was (4.43 ± 0.85) points, higher than that of the control group (3.85 ± 1.08) points, with a statistically significant difference ( t=3.30, P<0.05). The incidence rates of skin allergic reactions were 3.28%(2/61) and 4.92%(3/61) in the observation group and the control group, respectively, with no statistically significant difference ( P>0.05). Conclusions:The vest-type breast dressing bra designed in this study can properly secure the medicinal paste, reduce the rate of medication detachment, medication displacement, clothing contamination, and enhance patient satisfaction. It facilitates the external application of traditional Chinese medicine for patients with GLM and is worthy of clinical promotion.

Objective:To explore the relationship between suicide attempts,school bullying,and psychological resilience in children and adolescents with major depressive disorder(MDD)and school bullying and psychological resilience.Methods:A total of 784 patients with MDD aged 10 to 18 years were included.The Chinese version of the Olweus Bullying Victimization Questionnaire,Adolescent Psychological Resilience Scale,and a suicide attempt assessment were utilized to evaluate school bullying,psychological resilience,and suicide attempt.Stepwise logistic regression was applied to identify the associated factors of suicide attempts.Results:The occurrence of suicide at-tempts in children and adolescents with MDD was positively associated with physical bullying(OR=1.85,95％CI:1.14-3.02)and indirect bullying(OR=1.48,95％CI:1.06-2.04),and negatively associated with higher levels of goal focus(OR=0.62,95％CI:0.45-0.85)and positive cognition(OR=0.62,95％CI:0.45-0.85)at higher levels.Conclusion:Bullying significantly increases the risk of suicide attempts in children and adolescents with MDD,while higher psychological resilience could mitigate this risk.
