Objective:To explore the typology and influencing factors of nursing undergraduates'career willingness to care for terminally ill elderly patients.Methods:Using a convenience sampling method,a survey was conducted among 488 nursing undergraduates from three universities in Hunan Province between May and June 2024.Latent profile analysis(LPA)was employed to classify career willingness to care for terminally ill elderly patients,and logistic regression analysis was used to analyze factors influencing the career willingness.Results:Heterogeneity was observed in nursing undergraduates'career willingness,which was categorized into three groups:low positive attitude-low care awareness group(24.8%),high positive attitude-low care awareness group(56.7%),and high positive attitude-high care awareness group(18.5%).Logistic regression analysis revealed that gender,cohabitation with terminally ill elderly patients,only-child status,experience in caring for terminally ill patients,geriatric nursing training,and hospice care education were statistically significant factors influencing career willingness(P＜0.05).Conclusions:Nursing undergraduates'career willingness to care for terminally ill elderly patients exhibits distinct categorical characteristics.Individualized educational strategies should be developed to enhance their professional identity and career intention in this field.

Objective:To investigate the effects of scalp acupuncture of Baihui and Qubin acupoints combined with running track exercise on the neurological function of rats with middle cerebral artery occlusion(MCAO)cerebral ischemia and its regulatory effect on the Nrf2/HO-1 pathway by focusing on oxidative stress injury.Methods:A total of 40 male SD rats of SPF grade were selected and the cerebral ischemia model was established by ligation method.Among them,30 rats with successful modeling were randomly divided into the model group,the scalp-acupuncture group,and the combined group,with 10 rats in each group.Another 10 SPF male SD rats were used as the sham operation group.In the scalp-acupuncture group,electroacupuncture was applied to Baihui and Qubin acupoints.In the combined group,both electroacupuncture and running track exercise were applied.The treatment was carried out 6 times/week for a total of 4 weeks.The neurobehavioural function of rats was evaluated by Bederson Neurological Function Assessment.Pathological changes of rat brain tissue were observed by HE staining.SOD,serum MDA and GSH-px levels were detected by kit.The protein expression levels of Nrf2 and HO-1 in the rat brain tissue were detected by Western blot.Results:Compared with the sham-operated group,Bederson's neurological function score in the model group was significantly higher(P＜0.05),the pathological damage of HE-stained brain tissue was obvious,the level of MDA significantly increased(P＜0.05),the levels of SOD and GSH-px decreased(P＜0.05),and the protein expression levels of Nrf2 and HO-1 were significantly reduced(P＜0.05).Compared with the model group,Bederson neurological function scores were reduced in each treatment group(P＜0.05),the brain histopathological damage was alleviated,the level of MDA was reduced(P＜0.05),the levels of SOD and GSH-px was elevated(P＜0.05),and the protein expression levels of Nrf2 and HO-1 were significantly increased(P＜0.05).The Bederson neurological function score and MDA level in the combined group were lower than those in the scalp-acupuncture group(P＜0.05),and the levels of SOD and GSH-px and the expression levels of Nrf2 and HO-1 proteins were significantly higher than those in the scalp-acupuncture group(P＜0.05).Conclusions:Scalp acupuncture can improve the neurobehavioural dysfunction and pathological damage caused by cerebral ischemia,increase the antioxidant capacity,and the specific mechanism may be related to the activation of the Nrf2/HO-1 pathway.And scalp acupuncture combined with running track exercise has a synergistic effect and is more advantageous for treatment.

Objective:To elucidate the effects of different morphologies and sizes of micro/nanomaterial on luminescence properties.Methods:Lu2O3:Eu3+micro-/nanocrystals with different morphologies were synthesized hydrothermally,and the effects of precursor concentration,reaction time,pH,and alkali source on morphology and photoluminescence were investigated.Products were calcined and then characterized for morphology and photoluminescence.Spectra were collected with 250 nm excitation,focusing on the O2-→Eu3+charge-transfer band(CTB)and Eu3+f-f transitions.Results:The use of NaOH,aqueous ammonia,or triethylamine yielded monodisperse square nanosheets after calcination,while the use of urea produced monodisperse and uniform nanospheres.Fluorescence measurements showed a strong CTB near 250 nm.Under 250 nm excitation,the emission comprised multiple peaks,with the the strongest being the 5D?→7F2 hypersensitive transition at 614 nm.Conclusions:In the hydrothermal system,alkali source and reaction parameters provide significant control over the morphology and size of Lu2O3:Eu3+micro-/nanocrystals.The morphology-dependent emission is dominated by red light at 614 nm(5D?→7F).

Objective:To provide a theoretical foundation for improving the evaluation of ideological and political education within medical curricula by comparing and analyzing the teaching effectiveness of AI-empowered ideological and political case teaching with conventional case teaching.Methods:Utilizing a cluster sampling method,two administrative classes who received the course of Preventive Medicine were selected,and randomly divided into the AI-empowered ideological and political case group(case 1 group)and the common case group(case 2 group).During the medical course instruction,each group received teaching sessions incorporating their respective case study content.A questionnaire survey was subsequently administered to compare the students'levels of acceptance and perception towards the ideological and political case teaching.Results:The students'recognition rates for"whether the ideological education cases could achieve the teaching objectives","the close combination of ideological education cases and preventive medicine professional knowledge"and"case teaching deepened students'understanding of doctors'social services"in Case 1 group were all higher than those in Case 2 group(P＜0.05).There was no significant difference in the recognition rate for"the case content has practical guiding significance(such as response to public health events)","the case enhanced my sense of mission in the field of public health",and"the lecture process of the case impressed me"between the two groups(P＞0.05).Conversely,the recognition rate of the Case 2 group for"the integration of ideological education cases had more warmth"was higher than that of the Case 1 group(P＜0.05).Conclusion:Correctly evaluating and utilizing AI-empowered ideological and political case teaching in medical course education can more efficiently achieve the goals of ideological and political education.

Objective:To explore the correlation of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)parameters and serum level of proprotein convertase subtilisin/kexin type 9(PCSK9)with pathological characteristics and chemotherapy sensitivity of breast cancer patients.Methods:The clinical data of 102 breast cancer patients admitted to our hospital from Feb 2022 to May 2024 were respectively analyzed.Based on the principle of 1∶1 selection,102 patients with benign breast tumors during the same period were selected as the control group.The DCE-MRI parameters[transport constant(Ktrans),rate constant(Kep),volume ratio of the external space(Ve),and apparent diffusion coefficient(ADC)]and serum PCSK9 level were compared between the two groups and patients with different pathological characteristics,and the correlation was analyzed.The value of DCE-MRI parameters(Ktrans,Kep,Ve,ADC)combined with serum PCSK9 level in assessing the sensitivity of chemotherapy in breast cancer patients was analyzed.Results:The Ktrans,Kep,Ve,ADC values,and serum PCSK9 level in breast cancer group were higher than those in the benign breast tumor group(P＜0.01).Breast cancer patients with low-to-moderate differentiation,pathological stage Ⅲ,and lymph node metastasis had higher Ktrans,Kep,Ve,ADC values,and serum PCSK9 level compared to those with high differentiation,pathological stage Ⅰ-Ⅱ,and no lymph node metastasis(P＜0.05).The degree of differentiation,pathological stage,and lymph node metastasis were positively correlated with Ktrans,Kep,Ve,ADC values,and serum PCSK9 level(P＜0.01).The Ktrans,Kep,Ve,ADC values,and serum PCSK9 level in breast cancer patients with chemotherapy resistance were higher than those in patients with chemotherapy sensitivity(P＜0.01).Patients with chemotherapy resistance had a higher proportion of low-to-moderate differentiation,pathological stage Ⅲ,and lymph node metastasis than patients with chemotherapy sensitivity(P＜0.05).After adjusting the degree of differentiation,pathological stage and lymph node metastasis,Ktrans,Kep,Ve,ADC values and serum PCSK9 level were still the influencing factors of chemotherapy sensitivity in breast cancer patients(P＜0.05).Conclusion:DCE-MRI parameters and serum PCSK9 level are correlated with the clinical pathological characteristics of breast cancer patients,and the combination of these indicators can provide certain reference value for clinical evaluation of chemotherapy sensitivity in breast cancer patients.

Objective:To evaluate the current status of satisfaction with community and home-based integrated elderly care and medical services in Chengdu and explore its influencing factors,providing policy recommendations for service optimization.Methods:A purposive sampling method was used to conduct a satisfaction survey among elderly in seven institutions in Chengdu with community and home-based integrated elderly care and medical services.Binary logistic regression were employed to analyze influencing factors of satisfaction with the services.Results:The overall satisfaction score for community and home-based integrated elderly care and medical services was(4.19±0.41).The highest satisfaction was reported for traditional Chinese medicine appropriate techniques healthcare services,whereas the lowest satisfaction was observed for rehabilitation knowledge training services for family members or other caregivers.Binary logistic regression analysis revealed that ethnicity,living arrangement,and depressive status were significant influencing factors(P＜0.05).Conclusions:The elderly in Chengdu exhibit relatively high overall satisfaction with community and home-based integrated elderly care and medical services.More attention should be paid to improving service accessibility for the elderly with mental health issues,promoting TCM services,strengthening rehabilitation nursing service systems,encouraging family or community participation in caregiving,and optimizing the social support network for community and home-based integrated elderly care and medical services.

Objective:To explore the correlation between elderly education and health status of elderly people in urban and rural areas.Methods:A cross-sectional survey was conducted from Jul 2024 to Dec 2024 involving 200 elderly people aged 60 and above in Shenyang.Among them,62 participated in elderly education and 138 did not.The psychological and health status of the two groups were evaluated using the Satisfaction with Life Scale(SWLS),Hamilton Anxiety and Depression Scale,Montreal Cognitive Assessment Scale,and a self-designed questionnaire on health status.Results:There were statistically significant differences in age,years of education,occupation(before retirement),living conditions,and residential location between the two groups(P＜0.05).There were statistically significant differences in life satisfaction,delayed recall ability,and occurrence of physical limitations between the two groups(P＜0.05).Conclusion:Conducting elderly education for the elderly population is of great significance in promoting their physical and mental health,promoting the construction of a positive aging concept,and establishing a comprehensive elderly health system.

Objective:To conduct a scoping review of financial toxicity assessment tools both domestically and internationally,and to summarize their scoring methods,evaluation content,development approaches,reliability/validity,and application status,aiming to provide references for selecting or developing such tools.Methods:Following scoping review methodology,databases including CNKI,VIP,Wanfang,PubMed,Web of Science,Embase,and CINAHL were searched for studies on financial toxicity assessment tools,with the search period spanning from database inception to Oct 8,2024.Results:A total of 34 eligible studies were included,covering 14 financial toxicity assessment tools.These tools primarily focused on economic status,psychosocial responses,or coping behaviors.Tools developed by domestic scholars exhibited strong specificity but lacked generalizability.Conclusions:Existing financial toxicity assessment tools are diverse,yet their reliability and validity in Chinese patient populations require further validation.Most scales lack comprehensive dimensions,and domestically developed tools are overly specific.A universal assessment tool suitable for China's cultural and policy environment needs to be developed.

Objective:To investigate the influencing factors of post-treatment recurrence in children with hemangioma and construct a nomogram prediction model.Methods:A total of 280 children with hemangioma treated with propranolol in our hospital from May 2021 to May 2023 were enrolled and divided into the recurrence group(71 cases)and the non-recurrence group(209 cases)based on post-treatment outcomes.Multivariable logistic regression was performed to analyze the factors influencing the recurrence of hemangioma.R package 4.0'rms'was used to construct a nomogram model for predicting the recurrence.Calibration and decision curves were used to internally validate the nomogram model and evaluate the clinical prediction effectiveness.Results:Multivariable logistic regression analysis showed that hemangioma type(OR=1.754,95%CI:1.102-3.565),medication dosage(OR=1.774,95%CI:1.132-4.993),treatment duration(OR=1.841,95%CI:1.142-5.845),age at initial medication(OR=1.695,95%CI:1.104-3.450),and age at treatment discontinuation(OR=1.889,95%CI:1.218-5.254)were independent risk factors of post-treatment recurrence of hemangioma among the children(P＜0.05).The calibration curve of the nomogram model closely aligned with the original and ideal curves,with a C-index of 0.810(0.746-0.873).The decision curve showed that the threshold value of the nomogram model was＞0.17,with high net clinical benefit for all of them,and was higher than the hemangioma type,medication dosage,treatment duration,age at initial medication,and age at treatment discontinuation.Conclusions:The factors affecting post-treatment recurrence in children with hemangiomas are hemangioma type,medication dosage,treatment duration,age at initial medication,and age at treatment discontinuation.A nomogram model constructed using these factors as predictors can help to predict and evaluate post-treatment recurrence in children with hemangiomas,enabling early intervention and improved prognosis.

Objective:To investigate the clinical significance and predictive efficacy of serum homocysteine(Hcy)and interleukin-6(IL-6)in women with early-pregnancy recurrent spontaneous abortion(RSA).Methods:From Aug 2021 to Aug 2024,35 women with early-pregnancy RSA were selected from Changzhi People's Hospital and designated as the RSA group,and 44 women with no history of recurrent miscarriage in early pregnancy were chosen as the control group.Enzymatic cycling assay was used to determine the serum Hcy level,and immunofluorescence assay was used to detect the serum IL-6 level.Binary logistic regression model was applied to assess the potential impact of serum Hcy and IL-6 levels on RSA.Receiver operating characteristic(ROC)curve was utilized to evaluate the diagnostic value of serum Hcy and IL-6 levels for RSA.Results:RSA group exhibited significantly higher Hcy levels(P＜0.01)and lower IL-6 levels(P＜0.01)compared to the control group.High level of serum Hcy(OR=1.628,95%CI:1.169-2.266)and low level of serum IL-6(OR=0.478,95%CI:0.289-0.791)significantly affected recurrent miscarriage(P＜0.05).ROC analysis showed AUC values of 0.765(Hcy),0.851(IL-6),and 0.919(combined),with sensitivities of 65.7%,91.4%,and 77.1%,and specificities of 86.4%,59.1%,and 100%,respectively.Conclusions:There are significant differences in the levels of serum Hcy and IL-6 between RSA patients and healthy controls.Serum Hcy combined with IL-6 detection has certain diagnostic value for predicting RSA.
