Objective: To analyze the characteristics and key risk factors of abnormal blood disposal throughout the 2024-2025 blood collection and supply process based on nationwide multi-site monitoring data, develop a comprehensive prevention and control strategy across the entire chain, reduce preventable blood waste, and ensure clinical blood safety. Methods: According to the Guidelines for Haemovigilance (T/CSBT 001-2026), we extracted 74 cases of abnormal blood disposal events reported by the China Blood Transfusion Association′s Blood Safety Monitoring System from January 1 2024, to December 31 2025, and conducted descriptive statistical analysis on the distribution of events, types of deviations, root causes, and classifications of disposal manifestations. Results: A total of 664 adverse events related to blood collection and supply were reported over two years, with 74 cases involving discarded abnormal blood units, accounting for 11.1% of the total. Among these, blood component preparation (40.5%) and blood collection (37.8%) remained traditional high-risk stages. The proportion of blood waste occurring during storage, distribution, and transportation increased from 7.7% in 2024 to 34.3% in 2025. Deviations from standard operating procedures (SOP) by personnel were the primary cause, accounting for 74.3% of cases. Discarded blood units were categorized into four types: compromised closed blood bag systems (40 cases), mainly due to inadequate heat sealing, physical damage, or dropped bags; blood out of the cold chain (12 cases), primarily resulting from blood being left at work sites; imbalanced proportion of preservation solution (10 cases), mostly caused by blood collection volumes exceeding the standard capacity of blood bags; and other causes (12 cases). Conclusion: Human operational errors are the core cause of abnormal blood waste. The collection and preparation stages have long been at high-risk, and the risks in the storage and transportation stages have been increasing year by year. We should focus on standardizing personnel management, improving specialized operation norms such as heat sealing, transportation, and storage, establishing a full-process intelligent cold chain monitoring and multi-node visual verification mechanism, and systematically reducing the occurrence rate of abnormal blood waste through a closed-loop quality intervention system, thereby improving the utilization efficiency of voluntary blood donation resources.

Objective: To identify the latent classes of acceptance and striving and their associated factors among nursing students, and to examine the mediating role of positive acceptance and striving in the association between self transcendence and subjective well being, so as to provide evidence for targeted interventions to improve subjective well being among nursing students. Methods: From July to October 2025, a convenience sample of 861 nursing students was recruited from five schools in Sichuan and Chongqing, China. Participants were surveyed using the Self transcendence Scale, the Positive Acceptance and Striving Scale, and the General Well being Scale. Latent profile analysis was conducted to identify profiles of positive acceptance and striving. Logistic regression analysis was used to examine associated factors, and relative mediation analysis was performed to assess differences in the mediating effect across latent profiles. Results: Three latent classes of acceptance and striving were identified: the low acceptance-low striving profile (46.34%, n =399), the moderate acceptance-moderate striving profile (40.88%, n =352), and the high acceptance-high striving profile (12.78%, n =110). Multivariable Logistic regression analysis showed that, with the low acceptance-low striving profile as the reference, nursing students with higher self transcendence scores ( OR =151.85) and those who studied nursing because of personal preference ( OR =14.72) or parental expectations ( OR =11.16) were more likely to be classified into the high acceptance-high striving profile (all P <0.05). Male students ( OR =0.19), those perceiving nurses social status as average ( OR =0.35), and those receiving moderate teacher support ( OR =0.23) were less likely to be classified into the high acceptance-high striving profile (all P <0.05). Positive acceptance and striving partially mediated the association between self transcendence and subjective well being, with a total effect of β =0.97 and a mediating effect of β =0.48; the mediating effect accounted for 49.34% of the total effect. Relative mediation analysis showed that the mediating effect was statistically significant only in the low acceptance-low striving profile ( β =0.21), whereas the direct effects were stronger in the moderate acceptance-moderate striving and high acceptance-high striving profiles ( β =0.39, 1.06)(all P <0.05). Conclusions Positive acceptance and striving among nursing students exhibit substantial heterogeneity. Its predictive effect on subjective well being and the underlying mediating mechanism vary across latent profiles. Profile specific interventions should therefore be implemented to improve subjective well being among nursing students.

OBJECTIVE To investigate the mechanism by which resveratrol improves renal injury in rats with uric acid nephropathy （UAN） through inhibition of the protein kinase R-like endoplasmic reticulum kinase （PERK）/eukaryotic translation initiation factor 2α （eIF2α） pathway.METHODS A UAN rat model was established via oral administration of adenine plus potassium oxonate， and the rats were divided into a UAN model group， a positive control group （allopurinol 10 mg/kg）， a resveratrol group （100 mg/kg）， and a resveratrol+tunicamycin group [resveratrol 100 mg/kg+tunicamycin （PERK activator） 1 mg/kg]. A control group （without modeling） was also established， with 6 rats in each group. Rats in each group were administered the corresponding drug solution and/or normal saline via gavage or intraperitoneal injection once daily for 28 consecutive days. The contents of renal function-related parameters （24-hour urinary total protein， and uric acid， creatinine and blood urea nitrogen in serum）， the levels of inflammation-related markers [interleukin-6 （IL-6）， IL-18， tumor necrosis factor-α （TNF-α）， IL-10， and nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3）]， and pathological changes in renal tissue were determined， and the score for tubular damage， the score for inflammatory infiltration， and the degree of mesangial proliferation were assessed. The mRNA expressions of neutrophil gelatinase-associated lipocalin （NGAL） and kidney injury molecule-1 （KIM-1）， as well as the expressions of proteins associated with the PERK/eIF2α pathway， were measured in renal tissue from each group.RESULTS Compared with the control group， rats in the UAN model group exhibited marked tubular damage， inflammatory cell infiltration， and mesangial proliferation. The contents of renal function-related parameters， levels of IL-6， IL-18， TNF-α and NLRP3， scores for tubular damage and inflammatory infiltration， degree of mesangial proliferation， mRNA expressions of NGAL and KIM-1， and phosphorylation levels of PERK and eIF2α， as well as the expressions of activating transcription factor 4 and C/EBP homologous protein， were all significantly increased or upregulated， while IL-10 levels were significantly decreased （ P ＜0.05）. Compared with the UAN model group， the resveratrol group and the positive control group showed significant improvements in all of the aforementioned parameters （ P ＜0.05）. Tunicamycin could significantly reverse the beneficial effects of resveratrol on all quantitative parameters （ P ＜0.05）.CONCLUSIONS Resveratrol can reduce inflammatory responses in renal tissue of UAN rats， and improve tubular damage and renal function. These effects may be related to the inhibition of endoplasmic reticulum stress mediated by the PERK/eIF2α pathway.

Objective:To explore the effect of preoperative gamma-glutamyl transferase to albumin ratio (GAR) on prognosis of patients with Barcelona clinic liver cancer (BCLC)stage 0-A hepatocellular carcinoma (HCC) after microwave ablation (MWA).Methods:The clinical data of 201 patients with BCLC stage 0 to A who underwent MWA at two centers of Jiaxing Second Hospital and Shengjing Hospital of China Medical University from January 2011 to December 2018 were retrospectively analyzed, including 152 males and 49 females, aged (57.5±9.6) years. X-tile software was used to divide patients into a low GAR group ( n=84, GAR<0.9) and a high GAR group ( n=117, GAR≥0.9). Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival comparison. Univariate and multivariate Cox regression analysis was used to evaluate the relationship between GAR and prognosis. Results:The cumulative survival rates at 1, 3 and 5 years postoperatively were 98.7%, 93.8%, 78.5% for the low GAR group, which were superior to that 97.2%, 87.1%, 70.2% for the high GAR group, and the difference was statistically significant ( χ2=11.89, P=0.001). The recurrence-free survival rates at 1, 3 and 5 years after surgery between the two groups was no significant difference ( χ2=1.70, P=0.192). Multivariate analysis revealed that high GAR ( HR=2.723, 95% CI: 1.508-4.914, P=0.001) was independent risk factors for overall survival after MWA in patients with BCLC stages 0 to A HCC. Male gender ( HR=1.959, 95% CI: 1.127-3.305, P=0.017) and tumor diameter ≥2 cm ( HR=1.547, 95% CI: 1.008-2.373, P=0.046) were independent risk factors for recurrence after MWA in patients with BCLC stages 0 to A HCC. Univariate analysis, GAR≥0.9 was not associated with postoperative recurrence ( HR=1.315, 95% CI: 0.869-1.989, P=0.195). Conclusion:Preoperative GAR (≥0.9) is an independent risk factor affecting overall survival in patients with BCLC stages 0 to A HCC after MWA.

Objective To define the conceptual connotation of network dynamic collaboration capacity in medical surge response and construct its theoretical model.Methods A mixed concept analysis method was employed,integrating multidisciplinary literature and collecting empirical evidence through semi-structured expert interviews to extract the concept of network dynamic collaboration capacity in medical surge response.By integrating complex systems,network science,synergetics,and dynamic capability theory,and combining the interview results,the study used the analogy of flood control in hydraulic engineering to develop a"network-dynamic-collaboration"triangular capacity theoretical model.Results It reveals one antecedents(sudden external shocks have led to an abnormal and continuous surge in medical demand),six core attributes(information interconnection accessibility,dynamic resource adaptability,risk perception responsiveness,multi-party collaborative interactivity,service process adaptability elasticity,and learning iterative evolution),and four consequences(mitigation of crowding risk,protection of service continuity,minimization of crisis spillover,and enhancement of system resilience)for the network dynamic collaboration capacity in medical surge response.The theoretical model elucidates the coupling mechanisms among network structural resilience,dynamic regulation processes,and collaborative co-evolution in resisting medical surge.Conclusion The new concept and theoretical model proposed in this study deepen the understanding of medical surge response system mechanisms and offer a theoretical framework and practical guidance for strengthening the full-chain resilience of health emergency systems.

Objective To empirically analyze multiple pathways for enhancing medical surge response capacity and provide useful references for improving the resilience of health systems.Methods A comprehensive theoretical analysis framework for improving medical surge response capacity was constructed based on the 4S theory and collaborative governance theory.68 interview texts on medical surge response capacity conducted in July 2024 were selected as analysis samples.Using fuzzy-set Qualitative Comparative Analysis(fsQCA),7 conditional variables were selected from four dimensions:management system,information system,materials,and personnel to analyze their impact on medical surge response capacity.Results(1)A single conditional variable does not constitute a necessary condition for improving medical surge response capacity;(2)After the combination of conditions,8 specific configuration paths for capacity improvement were identified.Through systematic and comprehensive refinement,they were summarized into three modes of comprehensive configuration capacity improvement paths,namely:rapid response and collaborative operation mode,information empowerment and precise response mode,and resource conditions and resilience construction mode.Conclusion It is necessary to explore and construct systematic,combined,modularized and path-oriented capacity building strategies,refine the operational implementation paths for improving China's medical surge response capacity,target the linkage and configuration modes of different conditional variables,promote the formulation and implementation of modular construction schemes oriented by key capacity,and make efforts from multiple aspects to enhance the resilience of the health system.

Objective:To construct a classification management model on the basis of Kraljic matrix for electrocardiogram(ECG)monitoring equipment in emergency intensive care unit(ICU),so as to explore its application value in the management for ECG monitoring equipment in emergency ICU.Methods:The classification management model on the basis of index for ECG monitoring equipment in emergency ICU was constructed.According to two classification dimensions included the market supply risk and the self-value,an indicator system of classification management,which aimed at strategic materials with high value and high risk,leverage materials with high value and low risk,bottleneck materials with low value and high risk,and conventional materials with low value and low risk,was constructed.A total of fifty-one ECG monitoring equipment in the emergency ICU of The People's Hospital of Longhua of Shenzhen from January to December 2023 were selected,and they were managed respectively by conventional management mode(25 sets)and classification management mode(26 sets)according to different management modes.The standardization level of operation management for equipment,the occurrence of safety risk and the level of management for equipment of the two management modes were compared,and the satisfaction of 30 relative personnel,who used and managed these equipment,for classification management of equipment also were compared.Results:The average values of the percentage of standardization level of normality of equipment operation,disinfection and sterilization,maintenance and fault repair of using classification management mode were respectively(91.58±4.33)%,(92.1±3.28)%,(91.49±3.54)%and(92.58±3.32)%,all of which were higher than those of conventional management mode,and the differences were statistically significant(t=12.537,15.706,14.196,18.946,P<0.05),repsectively.The average incidences of the risk of pressure injury,electrical injury and body fluid extravasation of adopting classification management mode were respectively(2.54±0.87)%,(3.02±0.82)%and(1.29±0.65)%,all of which were lower than those of adopting conventional management mode,and the differences were statistically significant(t=22.825,17.453,24.424,P<0.05),respectively.The satisfaction scores of 30 relative management personnel,who used equipment on the process rationality,system standardization and quality effectiveness,of adopting classification management mode were respectively(94.26±3.54),(92.57±4.36)and(91.87±3.69),all of which were higher than those of conventional management mode,and the differences were statistically significant(t=14.052,13.991,13.551,P<0.05),respectively.The reasonable placement rate,recording rate of standardization,and intact rate of equipment in the 26 equipment by adopting classification management mode were respectively 92.31%,92.31%and 88.46%,all of which were significantly higher than those by adopting conventional management mode,and the differences were statistical significant(x2=12.052,10.398,11.338,P<0.05).Conclusion:The classification management model of ECG monitoring equipment in emergency ICU can increase the management efficiency for the equipment in operating room of hospital,and improve the operation quality of equipment,and enhance the safety of equipment in clinical use,and the standardization of operation management for equipment.

Objective To explore the clinical value of the platelet count(PLT)to high-density lipoprotein cholesterol(HDL-C)ratio(PHR)in predicting poor prognosis after intravenous thrombolysis in patients with acute cerebral infarction(ACI).Methods A total of 304 patients with ACI who received intravenous thrombolytic therapy in this hospital from January 2021 to December 2023 were selected as the research sub-jects.According to the modified Rankin scale score at 6-month follow-up,the 304 patients with ACI were di-vided into the good prognosis group(n=216)and the poor prognosis group(n=88).Clinical data of all pa-tients were collected.The levels of PLT,HDL-C and PHR were compared between the two groups.The pre-dictive value of PLT,HDL-C and PHR for the prognosis of ACI patients was analyzed by using the receiver operating characteristic(ROC)curve.Binary Logistic stepwise regression analysis was used to explore the in-fluencing factors of prognosis in ACI patients.Results Compared with the good prognosis group,the HDL-C level in the poor prognosis group decreased,while the PLT level and PHR increased(P＜0.05).The results of the ROC curve showed that the area under the curve(AUC)and 95％CI of PLT,HDL-C,and PHR for pre-dicting poor prognosis after intravenous thrombolysis in ACI patients was 0.829(0.784-0.874),0.743(0.693-0.788),and 0.918(0.873-0.968),respectively.The AUC of PHR in predicting poor prognosis af-ter intravenous thrombolysis in ACI patients was higher than that of PLT and HDL-C alone(Z=13.239,10.776,P＜0.001).The proportions of National Institutes of Health Stroke Scale(NIHSS)score ≥8 points at admission,transformation of previous symptomatic hemorrhage,combined hypertension,and combined dia-betes in the poor prognosis group were all higher than those in the good prognosis group(P＜0.05).The re-sults of binary Logistic stepwise regression showed that the NIHSS score at admission(OR=2.565,95％CI:1.292-5.094),the transformation of previous symptomatic hemorrhage(OR=2.073,95％CI:1.179-8.645),and PHR(OR=3.732,95％CI:2.037-6.839)were risk factors for poor prognosis in ACI patients(P＜0.05).Conclusion PHR is expected to become an important reference index for predicting the prognosis of ACI patients after intravenous thrombolysis therapy.PHR,NIHSS score at admission,and the transforma-tion of previous symptomatic hemorrhage are all influencing factors for the prognosis of ACI patients after in-travenous thrombolysis therapy.

Objective:To investigate the correlation between the timing of minimally invasive puncture drainage and the outcome of patients with hypertensive intracerebral hemorrhage (HICH) in the basal ganglia region.Methods:Patients with HICH in the basal ganglia region underwent minimally invasive puncture and drainage at Hanchuan People's Hospital from January 2019 to September 2023 were selected. According to the timing of surgery, the patients were divided into onset to surgery time ≤12-hour group and >12-hour group. According to the modified Rankin Scale score at 90 days after onset, they were divided into a good outcome group (0-2) and a poor outcome group (>2). Multivariate logistic regression analysis was used to evaluate the independent influencing factors of functional outcome. Results:A total of 150 patients were included, with 78 males (52.00%), aged 53.15±4.35 years (range, 40-75 years). Eighty-six patients (57.33%) underwent surgery within 12 hours after onset, while 64 (42.67%) underwent surgery after 12 hours; 97 patients (64.67%) had good outcome, while 53 (35.33%) had poor outcome. Univariate analysis showed that compared with the onset to surgery time ≤12-hour group, the onset to surgery time >12-hour group had a longer time from onset to admission, a larger postoperative hematoma volume, longer hospitalization time, lower postoperative hematoma clearance rate, and a higher proportion of patients with poor outcome and deaths within 90 days (all P<0.05). Compared with the good outcome group, the poor outcome group had a longer time from onset to admission, higher baseline National Institutes of Health Stroke Scale (NIHSS) scores, larger baseline and postoperative hematoma volumes, and a higher proportion of patients with onset to surgery time >12 hours. However, the postoperative hematoma clearance rate, baseline Glasgow Coma Scale (GCS) score, and the proportion of patients with baseline GCS score >8 was lower in the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that the higher baseline NIHSS score (odds ratio [ OR] 1.847, 95% confidence interval [ CI] 1.362-2.503; P=0.001) and the time from onset to surgery >12 hours (compared with ≤12 hours: OR 1.347, 95% CI 1.058-1.715; P=0.016) were the independent risk factors for poor outcome, while higher baseline GCS scores ( OR 0.723, 95% CI 0.558-0.937; P=0.006) and higher postoperative hematoma clearance rates ( OR 0.615, 95% CI 0.462-0.819; P=0.004) were the independent protective factors for good outcome. Conclusion:In patients with HICH in basal ganglia, it is ideal to perform minimally invasive puncture and drainage within 12 h after onset, and the postoperative recovery is relatively better.

OBJECTIVES: To analyze the efficacy and safety of concomitant left atrial appendage clipping during heart valve surgery for valvular heart disease patients with atrial fibrillation. METHODS: Fifty-eight patients who underwent concomitant left atrial appendage clipping during cardiac valve surgery in the Second Affiliated Hospital of Nanchang University from January 2017 to June 2023 were included in the analysis, including 1 case who underwent aortic valve replacement, 49 cases who underwent mitral valve replace-ment (or valvuloplasty)+tricuspid valvuloplasty, and 8 cases who underwent double valve replacement+tricuspid valvuloplasty (3 cases combined with coronary artery bypass grafting). The patients were followed up for 3-36 months [(16.69±6.61) months] after operation, and the changes of cardiac function and the occurrence of serious adverse complications were evaluated. RESULTS: The cardiopulmonary bypass time ranged from 75 to 145 min [(102.50±21.03) min], and the aortic cross-clamp time ranged from 35 to 80 min [(58.02±14.63) min]. The length of postoperative intensive care unit stay was 1 to 5 days [(2.47±0.82) d], and the length of postoperative hospital stay was 7 to 22 days [(10.84±2.69) d]. Cardiac ultrasound indicated complete closure of the left atrial appendage in all cases. During the follow-up, New York Heart Association (NYHA) functional classifications were improved in 54 patients. No left atrial appendage-related bleeding events or other perioperative complications were observed; and no cerebral infarction, limb embolism events, or mortality cases occurred during the follow-up. CONCLUSIONS For valvular heart disease patients with atrial fibrillation, concomitant left atrial appendage clipping during cardiac valve surgery demonstrates efficacy and safety, with no severe adverse events during a medium-term follow-up.
