Objective To explore the effectiveness of the generative large language model MedGo in nursing decision-making for elderly patients with multimorbidity. Methods A quasi-randomized controlled trial study was conducted involving 6 junior nurses, 6 senior nurses and the MedGo model from January 1, 2025 to March 31, 2025 at the Emergency Internal Medicine Ward of Shanghai East Hospital Affiliated to Tongji University. Clinical data of 120 elderly patients with multimorbidity were analyzed to compare the performance of the three groups in four tasks (nursing diagnosis assessment, nursing intervention formulation, complication identification, and complication prevention) from three evaluation dimensions: decision-making time consumption, decision accuracy, and decision-making quality. Results In terms of decision-making time, the senior nurse group completed all four tasks faster than the junior nurse group (P＜0.01), and the MedGo group completed all four tasks faster than the junior nurse group (P＜0.001) and the senior nurse group (P＜0.001). In terms of decision-making accuracy, senior nurse group scored higher than junior nurse group in all four tasks (P＜0.001), while the MedGo group outperformed the senior nurse group only in complication identification (P＜0.001). In terms of decision-making quality, the MedGo group scored higher than junior nurse group (P＜0.001) and senior nurse group (P＜0.001) in all four tasks. Conclusions The MedGo model demonstrates advantages of high efficiency, accuracy, and quality in nursing decision-making for elderly patients with multimorbidity; senior nurses outperform junior nurses in decision-making, providing diverse references for clinical nursing decision-making.

This article presented the diagnosis and treatment of three patients from the first imported familial clustering of clonorchiasis in Shanghai Municipality, and evaluated the value of different stool examination methods in non-endemic areas of clonorchiasis. In February 2026, the first case of clonorchiasis in this family was confirmed, and subsequent epidemiological surveys revealed that four family members all had a history of traveling to Guangdong Province and consuming raw freshwater fish. Stool samples were collected from all four individuals and detected for Clonorchis sinensis eggs using both machine smear method and the modified Kato-Katz thick smear method. C. sinensis infection was detected among three individuals using the Kato-Katz method, with severe [20 448 eggs per gram (EPG)], moderate (2 376 EPG), and mild infections (960 EPG) identified, respectively, and no C. sinensis eggs were identified in the remaining one stool sample. In contrast, only one infection was detected with the machine smear method, resulting in a underdiagnosis rate of 66.67% (2/3). All three confirmed cases were cured following standardized therapy. This article indicates that imported familial clustering clonorchiasis cases are highly occult in non-endemic areas, and the machine smear method has a high risk of underdiagnosis during initial screening. A two-tier diagnostic model combining “machine smear method for initial screening + Kato-Katz method for confirmation” is recommended.

Against the backdrop of digital transformation in higher education， the traditional teaching model has become inadequate to meet the demands for cultivating new-quality nursing talents. Nursing ethics teaching confronts several dilemmas， such as unbalanced regional development， disconnection between theory and practice， scattered teaching resources， and fragmented knowledge points. With the iterative update of modern digital technologies， the knowledge graph， due to its structured， semantic， scalable， and multi-source integrative characteristics， offers a technological pathway to address these issues. Based on the construction foundation of the Ministry of Education’s first batch of virtual teaching and research platforms for humanistic nursing courses， the nursing ethics artificial intelligence（Al）course was developed around the“thinking-research-teaching-learning”framework. By strengthening ideological and political guidance， constructing a curriculum knowledge graph， and promoting the deep integration of humanistic care and professional knowledge，the course realized intelligent support for research，learning，and teaching. This innovative education model provides a replicable paradigm for cultivating outstanding nursing talents equipped with humanistic literacy， digital competence， and advanced ethical thinking， while also offering references for the digital transformation of higher nursing education.

After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Objective To explore the clinical efficacy of dual plasma molecular adsorption(DPMAS)sequential plasma exchange(PE)artificial liver mode in the treatment of liver failure(LF).Methods Eighty-five patients with LF receiving the artificial liver treatment in the Affiliated Hospital of Zunyi Medical Univer-sity from January 2020 to December 2023 were selected as the study subjects and divided into the study group(n=52)and the control group(n=33)according to the different treatment modes.The study group conduc-ted DPMAS sequential PE treatment and the control group underwent the PE treatment.The liver function[total bilirubin(TBIL),alanine aminotransferase(ALT),aspartate aminotransferase(AST),serum albumin(ALB),globulin(GLO),prealbumin(PAB)],Hb,coagulation function[platelet(PLT),plasminogen activity(PTA),international normalized ratio(INR),fibrinogen(FIB)]before treatment and at 24 h after treatment were compared between the two groups.Results Compared with before treatment,the levels of TBIL,ALT,AST,GLO and Hb after the first and second treatment in the two groups were decreased,ALB level in the control group and PAB level after the second time treatment was increased(P＜0.05).Compared with after the first treatment,the levels of TBIL,ALT and GLO after the second treatment in the two groups and the levels of AST and Hb in the study group were decreased,ALB level in the study group and PAB level in the two groups were increased(P＜0.05).Compared with before treatment,the levels of PLT and FIB after the first treatment in the two groups and INR level in the control group were decreased,PTA level in the control group was increased(P＜0.05).Compared with before treatment,the levels of PLT,INR and FIB after the second treatment in the two groups were decreased,PTA level was increased(P＜0.05).Compared with be-fore treatment,the levels of PLT,INR and FIB after the second treatment in the two groups were decreased,and PTA level was increased(P＜0.05).Compared with after the first treatment,PTA level after the second treatment in the study group was increased and INR level was decreased.Conclusion PE and DPMAS sequen-tial PE all could improve the liver function in the patients with LF,moreover the two times treatment has more significant effect.

Background and Aims:Aortic aneurysm,a major cardiovascular disease with high mortality and disability rates,has emerged as a critical global public health challenge.Elevated body mass index(BMI)has been confirmed as an independent risk factor for aortic aneurysm.However,the long-term trends and heterogeneity of the disease burden attributable to high BMI in China-across sex,age,and region-remain insufficiently studied.This study,based on the Global Burden of Disease(GBD)database,aimed to analyze the changes in the disease burden of high BMI-related aortic aneurysm in China from 1990 to 2021 and compare these trends with those in global and socio-demographic index(SDI)-stratified regions.Methods:Data from GBD 2021 were used to extract mortality rates and disability-adjusted life years(DALY)due to aortic aneurysm attributable to high BMI in China from 1990 to 2021.Age-standardized mortality rate(ASMR)and age-standardized DALY rate(ASDR)were calculated.Long-term trends were assessed using the estimated annual percentage change(EAPC)and Joinpoint regression models.An autoregressive integrated moving average model was applied to project trends from 2022 to 2036.Results:During the study period,deaths and DALY from aortic aneurysms attributable to high BMI in China increased nearly sevenfold.ASMR rose from 1 to 3 per 100 000 population(EAPC=3.91),and ASDR increased from 23 to 74 per 100 000(EAPC=4.11),both showing a marked upward trend.Males consistently bore a higher burden across all age groups,particularly among those aged≥65 years.Decomposition analysis revealed that the increased burden in males was mainly driven by epidemiological improvements,while that in females was primarily attributable to population aging.Compared with the United States and global trends,China exhibited a faster increase in high BMI-related aortic aneurysm burden,which is projected to remain elevated over the next 15 years.Conclusion:The disease burden of aortic aneurysm attributable to high BMI continues to rise in China,with pronounced differences across sex and age.Targeted weight management,health interventions,and early screening strategies are urgently needed for high-risk populations to curb the upward trend and optimize public health resource allocation.

Objective To compare the distribution characteristics of retinal capillary non-perfusion areas(NPAs)across different layers and regions in patients with neovascular glaucoma(NVG)secondary to proliferative diabetic retinop-athy(PDR)versus those with PDR alone through wide-field swept-source optical coherence tomography angiography(SS-OCTA)and to analyze the impacts of NPAs on the development of NVG.Methods This prospective cross-sectional study enrolled 33 patients with PDR(33 eyes,the PDR group)and 30 patients with NVG(30 eyes,the PDR+NVG group)diag-nosed at Affiliated Hospital of Shandong Second Medical University(formerly Weifang Medical University)from January 2022 to June 2023.The fundus examination was performed using SS-OCTA,and the NPA boundaries of the superficial capil-lary plexus(SCP)and deep capillary plexus(DCP)of the retina were manually delimited with the aid of ImageJ.The reti-na was divided based on two methods.Specifically,according to different concentric circles,the retina could be divided in-to the foveal area,parafoveal area,perifoveal area,annulus6-9,annulus9-12,annulus12-retinal boundary;besides,the ret-ina could also be divided into four quadrants(supratemporal,infratemporal,supranasal,and infranasal quadrants)based on the horizontal and vertical lines centered on the macular fovea.Based on that,the NPA area and ischemia index(ISI)in each layer and subdivision of the two groups of patients were counted.Additionally,the NPA and ISI in different concentric circles and different quadrants of the SCP and DCP were compared between the two groups.Moreover,the distribution characteristics of NPAs as well as the effect of NPAs on NVG were analyzed.Results(1)The NPA area and ISI in the DCP were larger than those in the SCP in both groups(all P＜0.001);the NPA area and ISI in the SCP and DCP of patients in the PDR+NVG group were larger than those in the PDR group(all P＜0.001).(2)In the supratemporal,infratemporal,supranasal,and infranasal quadrants,the NPA area and ISI in the SCP and DCP of patients in the PDR+NVG group were larger than those in the PDR group(all P＜0.01).The NPA area in the inferotemporal quadrant was the largest in the SCP and DCP,respectively,within each group(all P＜0.01).(3)The differences in the NPA area and ISI between the two groups were statistically significant in the annulus6-9,annulus9-12,and annulus12-retinal boundary in the SCP and DCP(all P＜0.01).The differences in the NPA area and ISI were statistically significant between different annular subdivisions in the SCP and DCP within each group(all P＜0.001).The multiple comparison results showed that the NPA area and ISI of the annulus12-retinal boundary in the SCP and DCP were larger than those in other annuli in both groups(all P＜0.05).The NPA area and ISI of the annulus9-12 were larger than those of the parafoveal and perifoveal areas;the NPA area and ISI of the annulus6-9 were larger than those of the parafoveal area(all P＜0.05).There was no statistically significant differ-ence in the NPA area and ISI in the remaining annuli(all P＞0.05).(4)The multivariate logistic regression analysis showed that the NPA area and ISI in the subnasal quadrant of the SCP were negatively correlated with the risk of NVG sec-ondary to PDR(P=0.036 and 0.038).The increased NPA area and ISI in the subnasal quadrant of the DCP were risk fac-tors for NVG secondary to PDR,and they may increase the risk of NVG(P=0.029 and 0.028).Conclusion The in-creased NPA area and ISI in the subnasal quadrant of the DCP were risk factors for secondary NVG in patients in the PDR group.

Traditional development of small protein scaffolds has relied on display technologies and mutation-based engineering, which limit sequence and functional diversity, thereby constraining their therapeutic and application potential. Protein design tools have significantly advanced the creation of novel protein sequences, structures, and functions. However, further improvements in design strategies are still needed to more efficiently optimize the functional performance of protein-based drugs and enhance their druggability. Here, we extended an evolution-based design protocol to create a novel minibinder, BindHer, against the human epidermal growth factor receptor 2 (HER2). It not only exhibits super stability and binding selectivity but also demonstrates remarkable properties in tissue specificity. Radiolabeling experiments with ^99mTc, ⁶⁸Ga, and ¹⁸F revealed that BindHer efficiently targets tumors in HER2-positive breast cancer mouse models, with minimal nonspecific liver absorption, outperforming scaffolds designed through traditional engineering. These findings highlight a new rational approach to automated protein design, offering significant potential for large-scale applications in therapeutic mini-protein development.

Objective To analyze the trends in the disease burden of schistosomiasis in China from 1992 to 2021, and to project the disease burden of schistosomiasis in China from 2022 to 2030, so as to provide insights into the elimination of schistosomiasis in China. Methods The prevalence, age-standardized prevalence, disability-adjusted life year (DALYs) rate and age-standardized DALYs rate of schistosomiasis, as well as the years lost due to disability (YLDs) rate and age-standardized YLDs rate of anemia attributable to Schistosoma infections in China, the world and different socio-demographic index (SDI) regions were captured from the Global Burden of Disease Study 2021 (GBD 2021) data resources, and the trends in the disease burden due to schistosomiasis were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI). In addition, the age, period and cohort effects on the prevalence of schistosomiasis were examined in China using an age-period-cohort (APC) model, and the disease burden of schistosomiasis was predicted in China from 2022 to 2030 using a Bayesian age-period-cohort (BAPC) model. Results The age-standardized prevalence and DALYs rate of schistosomiasis, and the age-standardized YLDs rate of anemia attributable to Schistosoma infections were 761.32/10⁵, 5.55/10⁵ and 0.38/10⁵ in China in 2021. These rates were all lower than the global levels (1 914.30/10⁵, 21.90/10⁵ and 3.36/10⁵, respectively), as well as those in the medium SDI regions (1 413.61/10⁵, 12.10/10⁵ and 1.93/10⁵, respectively), low-medium SDI regions (2 461.03/10⁵, 26.81/10⁵ and 4.48/10⁵, respectively), and low SDI regions (5 832.77/10⁵, 94.48/10⁵ and 10.65/10⁵, respectively), but higher than those in the high SDI regions (59.47/10⁵, 0.49/10⁵ and 0.05/10⁵, respectively) and high-medium SDI regions (123.11/10⁵, 1.20/10⁵ and 0.12/10⁵, respectively). The prevalence and DALYs rate of schistosomiasis were higher among men (820.79/10⁵ and 5.86/10⁵, respectively) than among women (697.96/10⁵ and 5.23/10⁵, respectively) in China in 2021, while the YLDs rate of anemia attributable to Schistosoma infections was higher among women (0.66/10⁵) than among men (0.12/10⁵). The prevalence of schistosomiasis peaked at ages of 30 to 34 years among both men and women, while the DALYs rate of schistosomiasis peaked among men at ages of 15 to 19 years and among women at ages of 20 to 24 years. The age-standardized prevalence of schistosomiasis showed a moderate decline in China from 1992 to 2021 relative to different SDI regions [EAPC = -1.51%, 95% CI: (-1.65%, -1.38%)], while the age-standardized DALYs rate [EAPC = -3.61%, 95% CI: (-3.90%, -3.33%)] and age-standardized YLDs rate of anemia attributable to Schistosoma infections [EAPC = -4.16%, 95% CI: (-4.38%, -3.94%)] appeared the fastest decline in China from1992 to 2021 relative to different SDI regions. APC modeling showed age, period, and cohort effects on the trends in the prevalence of schistosomiasis in China from 1992 to 2021, and the prevalence of schistosomiasis appeared a rise followed by decline with age, and reduced with period and cohort. BAPC modeling revealed that the age-standardized prevalence and age-standardized DALYs rate of schistosomiasis, and age-standardized YLDs rate of anemia attributable to Schistosoma infections all appeared a tendency towards a decline in China from 2022 to 2030, which reduced to 722.72/10⁵ [95% CI: (538.74/10⁵, 906.68/10⁵)], 5.19/10⁵ [95% CI: (3.54/10⁵, 6.84/10⁵)] and 0.30/10⁵ [95% CI: (0.21/10⁵, 0.39/10⁵)] in 2030, respectively. Conclusions The disease burden of schistosomiasis appeared a tendency towards a decline in China from 1992 to 2021, and is projected to appear a tendency towards a decline from 2022 to 2030. There are age, period and cohort effects on the prevalence of schistosomiasis in China. Precision schistosomiasis control is required with adaptations to current prevalence and elimination needs.

BACKGROUND:The imbalance between proliferation and apoptosis of chondrocytes plays an important role in the occurrence and development of osteoarthritis. Previous studies have found that hsa-miR-3202 is involved in regulating the proliferation and apoptosis of various cells. However,no studies have explored the correlation between hsa-miR-3202 and osteoarthritis.OBJECTIVE:To investigate the expression of hsa-miR-3202 in osteoarthritic chondrocytes and its effect on the proliferation and apoptosis of chondrocytes. METHODS:(1) MicroRNAs differentially expressed in osteoarthritic chondrocytes were screened by biogenic analysis. Based on the current research situation at home and abroad,hsa-miR-3202 was selected for follow-up studies,and its target genes were predicted by gene ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. (2) Human normal chondrocyte cell lines C28/I2 in logarithmic growth phase were selected and randomly divided into four groups for culture:in normal group,cells were cultured in normal medium for 24 hours,the medium was then changed to normal medium for another 6 hours of culture,and changed to normal medium for subsequent culture;in lipopolysaccharide group,cells were cultured in lipopolysaccharide-containing medium for 24 hours,the medium was then changed to normal medium for another 6 hours,and changed to normal medium for subsequent culture;in lipopolysaccharide+NC group,cells were cultured in lipopolysaccharide-containing medium for 24 hours,and then transfected with has-miR-3202 mimics control for 6 hours,and the medium was change to normal medium for subsequent culture;in lipopolysaccharide+hsa-miR-3202 mimics group,cells were cultured in lipopolysaccharide-containing medium for 24 hours and then transfected with has-miR-3202 mimics for 6 hours,and the medium was changed to normal medium for subsequent culture. After further 48 hours of culture,the expression level of hsa-miR-3202 was detected by fluorescence quantitative PCR and cell apoptosis was detected by flow cytometry. After further culture of 0-72 hours,cell proliferation activity was detected by cell counting kit-8. RESULTS AND CONCLUSION:Bioinformatics analysis results indicated that hsa-miR-3202 was significantly down-regulated in osteoarthritic chondrocytes. GO functional enrichment and KEGG pathway enrichment showed that the function of hsa-miR-3202 target gene was closely related to cell growth and apoptosis. The results of in vitro cell experiments showed that compared with the normal group,the expression level of hsa-miR-3202 and proliferation ability of chondrocytes were significantly decreased in the lipopolysaccharide group (P<0.05),while the apoptotic rate was significantly increased (P<0.05). Compared with the lipopolysaccharide group,the expression level of hsa-miR-3202 and proliferation ability of chondrocytes were significantly increased in the lipopolysaccharide+hsa-miR-3202 mimics group (P<0.05),while the apoptotic rate was significantly decreased (P<0.05). To conclude,the expression of hsa-miR-3202 is down-regulated in osteoarthritic chondrocytes to inhibit cell proliferation and promote cell apoptosis,thus affecting the occurrence and development of osteoarthritis.
