ObjectiveTo introduce visual teaching into the course design of medical humanistic care based on the concept of implementation science， evaluate the teaching implementation effect and feedback， and provide references for optimizing course teaching outcomes and improving students’ humanistic care competence. MethodsA visual teaching program for medical humanistic care was designed， with key steps including clarifying teaching objectives， content， methods， and curriculum assessment. This program was implemented in the medical humanistic care course teaching involving 50 elective students. Multi-dimensional evaluation of teaching effectiveness was conducted through course grades， visual teaching evaluation， and humanistic workshop assessment， combined with inductive content analysis of students’ learning experiences in the workshops. ResultsThe 50 students achieved above-average course grades （89.60±3.41） and demonstrated high satisfaction with the overall course and visual teaching. All the 6 groups obtained relatively high scores in the medical humanistic care workshops. Four themes were extracted， namely， enhancing humanistic care competencies， deepening familial and interpersonal relationships， realizing emotional expression and self-growth， and strengthening integration of humanistic care concepts with practice. ConclusionThe teaching of medical humanistic care course has achieved favorable effects， which contributes to deepening students’ understanding of humanistic care and enhancing their humanistic care competence. Students demonstrate high levels of recognition and satisfaction with the course.

ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work， thereby providing a theoretical basis for the improvement of education and training， incentive mechanisms， and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method， semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest， empathy， and a sense of professional responsibility， while the negative was low psychological resilience. External positive driving forces included high work support， professional identity， mutual benefits for nurses and patients， and positive patient attitudes， whereas negative driving forces comprised busy routine clinical work， lack of a reward and incentive system， and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care， intensify the publicity of palliative care and death education； intervene and guide nurses’ negative emotions， improve and implement relevant incentive systems， and standardize the job recognition and scope of responsibilities of palliative care nurses.

Endometriosis （EMT） is a common disease with frequent occurrence and difficult to be cured in modern clinical practice of obstetrics and gynaecology. It is characterized by progressively worsening dysmenorrhoea， pelvic mass， and infertility. The incidence of EMT is growing and increasingly younger patients are diagnosed with this disease， which poses a serious threat to the reproductive and psychological health of women of childbearing age and adolescent females. However， the pathogenesis of EMT is still not completely clear， and the disease has a long course. Therefore， developing new therapies is an urgent clinical problem to be solved. Great progress has been achieved in the treatment of EMT with traditional Chinese medicine （TCM）， while the underlying mechanism remains in exploration. Programmed cell death （PCD） is a cell death mode mediated by a variety of bio-molecules with specific signaling cascades. The known PCD processes include apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis， which all play a pivotal role in the development of EMT. Researchers have made achievements in the treatment of EMT with TCM， which regulates PCD via multiple pathways， routes， targets， and mechanisms. However， the progress in the regulation of PCD in the treatment of EMT with TCM remains to be reviewed. This paper reviews the research progress in the treatment of EMT with TCM from five PCD processes （apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis）， with the aim of providing a theoretical basis for the clinical prevention and treatment of EMT.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Elderly end-of-life patients often experience distress due to being caught in dilemmas of contemplation and decision-making. Narrative wills， grounded in life values and premised on respecting individual wishes and needs， present an individual’s unique life story through narrative forms， conveying their overall experience， interpretation of meaning， and understanding of life. They are preserved and passed on in a way that meets individual expectations， thereby promoting human exploration， reflection， and growth regarding the meaning of life through interpersonal interactions that transcend space and time. This paper explored the concept of narrative wills among elderly end-of-life patients， the ethical value and ethical principles of narrative wills， and the moral and ethical risks. It also provided specific ethical interpretations， assisting in the application and development of narrative wills in elderly end-of-life patients.

Objective To explore the efficacy of Yishen Yangyin Gujing Prescription[derived from Zuogui Wan(Bolus for Replenishing Kidney-Yin)]for the treatment of diabetic nephropathy in type 2 diabetes mellitus(T2DM)with qi and yin deficiency syndrome,and to observe its effects on inflammatory responses,pancreatic β-cell function and renal function.Methods A total of 162 T2DM patients with diabetic nephropathy of qi and yin deficiency syndrome who admitted to the Affiliated Hospital of Shaanxi University of Chinese Medicine from May 2020 to July 2023 were randomly divided into an observation group and a control group according to the random number table method,with 81 cases in each group.The control group was given conventional western medicine treatment for lowering blood pressure and renal protection,while the observation group was treated with Yishen Yangyin Gujing Prescription on the basis of treatment for the control group.The course of treatment for the two groups covered 12 weeks.Before and after the treatment,the changes in the outcomes of the two groups were observed,and the outcomes included the total scores of traditional Chinese medicine(TCM)syndrome,insulin sensitivity index,insulin secretion index,24-h urine total protein quantification(24hUTP),and serum levels of glycosylated hemoglobin(HbA1c),fasting insulin(FINS),fasting blood glucose(FBG),serum creatinine(SCr),blood urea nitrogen(BUN),transforming growth factor β1(TGF-β1),NLRP3 inflammasome,interleukin 6(IL-6),superoxide dismutase(SOD)and sphingosine-1-phosphate(S1P).After treatment,the clinical efficacy of the two groups of patients was compared.Results(1)After 12-week treatment,the total effective rate of the observation group was 93.83%(76/81),and that of the control group was 83.95%(68/81).The intergroup comparison showed that the efficacy of the observation group was significantly superior to that of the control group(χ2=9.163,P<0.05).(2)After treatment,the insulin sensitivity index and insulin secretion index in the two groups of patients were increased(P<0.05)and the total scores of TCM syndromes were decreased(P<0.05)when compared with those before treatment,and the increase of insulin sensitivity index and insulin secretion index as well as the decrease of the total scores of TCM syndrome in the observation group was significantly superior to that in the control group(P<0.05).(3)After treatment,the serum levels of HbA1c,FINS,FBG,SCr,BUN and 24hUTP in the two groups of patients were decreased when compared with those before treatment(P<0.05),and the decrease of the above indicators in the observation group was significantly superior to that in the control group(P<0.05).(4)After treatment,the serum TGF-β1,IL-6,and NLRP3 inflammasome levels in the two groups of patients were decreased(P<0.05)and the serum S1P and SOD levels were increased(P<0.05)when compared with those before treatment,and the decrease of serum TGF-β1,IL-6,and NLRP3 inflammasome levels as well as the increase of serum S1P and SOD levels in the observation group was significantly superior to that in the control group(P<0.05).Conclusion For T2DM patients with diabetic nephropathy of qi and yin deficiency syndrome,the combined use of western medicine and Yishen Yangyin Gujing Prescription treatment is helpful to alleviate inflammatory response,improve the function of pancreatic β-cells,regulate the blood glucose level,improve renal function,and enhance the clinical efficacy.

Public health laboratory testing involves a wide range of sample types,complex matrices,diverse target analytes with varying concentrations,and multiple application contexts with different analytical requirements.As a critical step in public health laboratory analysis and testing,sample pretreatment plays a decisive role in ensuring the reproducibility and efficiency of the analytical methods.It directly affects the accuracy,sensitivity,and reliability of testing results,as well as the feasibility of downstream analyses.Traditional sample pretreatment techniques face persistent challenges,including low efficiency,limited throughput,restricted universal applicability,high organic solvent consumption,and poor compatibility with downstream analytical procedures.These limitations constrain their capacity to meet the evolving demands of research and practice in public health and preventive medicine.In recent years,technological advances have focused on improving efficiency and automation,enhancing selectivity and sensitivity,facilitating online testing capabilities,and promoting environmental sustainability.Sample pretreatment techniques in public health laboratory testing have been undergoing progressive upgrades,and numerous novel technologies have emerged.The paper provides a comprehensive review of new technologies and applications in the field.We focused on the development of new materials,the application of artificial intelligence,connections for online processing,and the approaches tailored to the demands of specific testing settings.We also discussed sample processing for omics analyses and mass spectrometry imaging methods relevant to public health laboratory testing.These advances are expected to support the development of greener and higher-throughput sample pretreatment and foster innovation in the public health laboratory testing system.

BACKGROUND: Preclinical studies have indicated that Angong Niuhuang Pills (ANP) reduce cerebral infarct and edema volumes. This study aimed to investigate whether ANP safely reduces cerebral infarct and edema volumes in patients with moderate to severe acute ischemic stroke. METHODS: This randomized, double-blind, placebo-controlled pilot trial included patients with acute ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores ranging from 10 to 20 in 17 centers in China between April 2021 and July 2022. Patients were allocated within 36 h after onset via block randomization to receive ANP or placebo (3 g/day for 5 days). The primary outcomes were changes in cerebral infarct and edema volumes after 14 days of treatment. The primary safety outcome was severe adverse events (SAEs) for 90 days. RESULTS: There were 57 and 60 patients finally included in the ANP and placebo groups, respectively for modified intention-to-treat analysis. The median age was 66.0 years, and the median NIHSS score at baseline was 12.0. The changes in cerebral infarct volume at day 14 were 0.3 mL and 0.4 mL in the ANP and placebo groups, respectively (median difference: -7.1 mL; interquartile range [IQR]: -18.3 to 2.3 mL, P = 0.30). The changes in cerebral edema volume of the ANP and placebo groups on day 14 were 11.4 mL and 4.0 mL, respectively ( median difference: 3.0 mL, IQR: -1.3 to 9.9 mL, P = 0.15). The rates of SAE within 90 days were similar in the ANP (3/57, 5%) and placebo (7/60, 12%) groups ( P = 0.36). Changes in serum mercury and arsenic concentrations were comparable. In patients with large artery atherosclerosis, ANP reduced the cerebral infarct volume at 14 days (median difference: -12.3 mL; IQR: -27.7 to -0.3 mL, P = 0.03). CONCLUSIONS: ANP showed a similar safety profile to placebo and non-significant tendency to reduce cerebral infarct volume in patients with moderate-to-severe stroke. Further studies are warranted to assess the efficacy of ANP in reducing cerebral infarcts and improving clinical prognosis. TRAIL REGISTRATION Clinicaltrials.gov , No. NCT04475328.

ObjectiveTo investigate the antidepressant effects and mechanisms of total flavonoids from Cuscutae Semen （TFCC） in the mouse model of chronic unpredictable mild stress （CUMS）. MethodsFifty male 4-week-old ICR mice were randomized into five groups （n=10 per group）： blank control， model， Cuscutae Semen decoction （10.2 g·kg^-1·d^-1）， paroxetine （2.6 mg·kg^-1·d^-1）， and TFCC （173.2 mg·kg^-1·d^-1）. The other groups except the blank control group underwent chronic unpredictable mild stress （CUMS） for 4 weeks. Behavioral assessments were conducted post-modeling. Then， the model group received distilled water （10 mL·kg^-1·d^-1）， while treatment groups were administrated with respective agents via oral gavage （10 mL·kg^-1） for 4 weeks. Depression-like behaviors were evaluated by the sucrose preference test （SPT）， forced swimming test （FST）， and tail suspension test （TST）. Hippocampal neuronal morphology was observed via hematoxylin-eosin staining， and apoptosis in the brain tissue was assessed via terminal- deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling （TUNEL）. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the hippocampal levels of inflammatory cytokines ［interleukin （IL）-1β， IL-6， and TNF-α）］ and neurotransmitters ［5-hydroxytryptamine （5-HT）， dopamine （DA）， and brain-derived neurotrophic factor （BDNF）］， while the reactive oxygen species （ROS） levels were quantified via the DCFH-DA probe. Real-time PCR was performed to measure the mRNA levels of NOD-like receptor protein 3 （NLRP3）， apoptosis-associated Speck-like protein containing a CARD （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， IL-1β， and inducible nitric oxide synthase （iNOS）. Western blot was employed to evaluate the protein levels of NLRP3， ASC， Caspase-1， uncoupling protein 2 （UCP2）， and thioredoxin-interacting protein （TXNIP）. ResultsCompared with the blank control group， the model group exhibited weight loss （P<0.01）， reduced sucrose preference （P<0.01）， prolonged immobility time in FST and TST （P<0.01）， neuron disarrangement with nuclear pyknosis in hippocampal CA3 region， increased apoptosis in the brain tissue， elevated levels of IL-1β， IL-6， and TNF-α （P<0.01）， declined levels of 5-HT， DA， and BDNF （P<0.01）， increased ROS accumulation （P<0.01）， upregulated mRNA levels of NLRP3， ASC， Caspase-1， IL-1β， and iNOS （P<0.01）， down-regulated protein level of UCP2 （P<0.01）， and up-regulated protein levels of NLRP3， ASC， Caspase-1， and TXNIP （P<0.01）. Compared with the model group， the interventions restored sucrose preference （P<0.01）， shortened immobility time （P<0.01）， repaired hippocampal neuronal structure， reduced apoptosis， lowered the levels of inflammatory cytokines （P<0.01）， restored the levels of neurotransmitters （P<0.01）， alleviated ROS accumulation （P<0.01）， downregulated the mRNA levels of NLRP3， ASC， Caspase-1， IL-1β， and iNOS （P<0.01）， upregulated the protein level of UCP2 （P<0.01）， and reduced the protein levels of NLRP3， ASC， Caspase-1， and TXNIP （P<0.01）. Moreover， TFCC outperformed Cuscutae Semen decoction in ameliorating depressive behaviors. TFCC excelled in neuronal repair， neurotransmitter regulation， anti-inflammatory effects， and modulation of the UCP2/TXNIP/NLRP3 pathway （P<0.05）. ConclusionTFCC modulates the hippocampal UCP2/TXNIP/NLRP3 pathway to inhibit inflammasome activation， reduce oxidative stress， restore neurotransmitters， thus suppressing neuronal apoptosis and promoting the rearrangement and morphology recovery of hippocampal cells. It outperforms Cuscutae Semen decoction in the antidepressant efficacy.
