Objective: To establish an accurate and rapid typing method for Rh typing of samples from patients who have received recent blood transfusions by utilizing the difference in osmotic fragility between fresh and old red blood cells. Methods: A lysing solution suitable for destroying old RBCs was prepared. Sixty-one samples collected in our hospital in 2024 with Rh typing of double groups were treated with the lysing solution to remove the old allogeneic red blood cells while preserving the patient's own fresh red blood cells, followed by repeat Rh typing tests. Results: For 61 samples with Rh typing in double groups, 41 were accurately detected identified through the red blood cell lysis method, yielding an identification rate of 67.21%. No significant difference was observed compared to the detection rate of the commonly used capillary centrifugation modified method (χ =0.103, P>0.05). Conclusion: The red blood cell lysis method provides a novel and rapid experimental approach for clinical use in processing Rh-typed samples that are of double groups, thereby offering a basis for Rh compatibility blood transfusion.

BackgroundStressful life events are associated with subclinical depressive and anxious symptoms， which may increase the risk of subsequent depressive and anxiety disorders. However， the mechanisms linking stressful life events to subclinical emotional symptoms remain unclear. ObjectiveTo explore the clinical characteristics of individuals with subclinical depression and anxiety following stressful events， and to analyze the mechanisms by which stressful events affect subclinical depressive and anxious symptoms， so as to provide a reference for the early identification and intervention of emotional symptoms in individuals under stress. MethodsFrom December 2024 to April 2025， 80 individuals with subclinical depression and/or anxiety （study group） and 80 healthy controls were recruited via the online official accounts of Beijing Anding Hospital， Capital Medical University and Beijing Huilongguan Hospital， Capital Medical University. Participants completed the Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， the Generalized Anxiety Disorder Scale-7 item （GAD-7）， the Life Event Scale （LES）， the Self-rating Idea of Suicide Scale （SIOSS）， and the Dysfunctional Attitude Scale （DAS）. Spearman rank correlation analysis was used to examine the associations in the study group. Serial mediation analyses were conducted using model 6 of Process version 4.1， to test whether cognitive distortion and hopelessness mediated the associations of stressful life events with subclinical depressive and anxious symptoms. ResultsCompared with healthy controls， participants with subclinical depressive and anxious symptoms had higher scores on PHQ-9， GAD-7， LES， SIOSS hopelessness subscale， and DAS scores （Z/t=10.294， 9.197， 4.659， 6.918， 3.517， P<0.01）. In the study group， GAD-7 score was positively correlated with LES， DAS， and SIOSS hopelessness subscale scores （r_s=0.233， 0.465， 0.588， P<0.05）； SIOSS hopelessness subscale score was positively correlated with DAS and LES scores （r_s=0.393， 0.309， P<0.01） and cognitive distortion was positively correlated with stressful life events（r_s=0.432， P<0.01）. Stressful life events were directly associated with subclinical anxiety symptoms （β=0.040， 95% CI： 0.015–0.065， P<0.05）， and showed a significant serial indirect association with subclinical anxiety symptoms （indirect effect=0.006， 95% CI： 0.001–0.017， P<0.01）， accounting for 7.15% of the total effect. Stressful life associated with subclinical depressive symptoms （β=0.087， 95% CI： 0.060–0.115， P<0.01）， however， the indirect effect through cognitive distortion and hopelessness were not statistically significant. ConclusionAfter experiencing stressful events， individuals with subclinical depression and anxiety exhibit more pronounced cognitive distortions and hopelessness. Stressful events can both directly affect subclinical anxiety symptoms and indirectly affect them through the serial mediating effects of cognitive distortion and hopelessness. Stressful events have a direct effect on subclinical depressive symptoms， whereas the mediating effects of cognitive distortion and hopelessness are no statistically significant. ［Funded by the Training Program for the Development of High-level Public Health Technical Talents （number， Academic Leader-01-22）； www.chictr.org.cn number， ChiCTR2400093516］

The “reciprocal work-family benefits” demonstrate that experiences from either professional or family roles enhance the performance and qualities of the other. A total of 4，431 narrative literacy questionnaires were returned from medical and nursing staff across seven provinces and municipalities in China. The results showed a positive correlation between professional development and family interaction （r=0.794， P<0.001）， namely， the improvement of medical and nursing staff’s professional narrative competence can facilitate family narrative interaction， and vice versa. Stemming from the viewpoint of reciprocal work-family enrichment from conservation of resources theory， this paper elaborated on why family and professional roles are taken into account during the development of the Chinese Medical Professionals’ Narrative Competence Scale. Traditional views regarded profession and family as opposing relationships in resource competition， whereas Chinese narrative medicine regarded medical professionals， who simultaneously occupy multiple roles， as a “whole.” The latter advocated for the construction of multidimensional positive narrative connections between medical professionals and themselves， families， workplaces， and society， to prevent medical professionals from suffering narrative closure and occupational burnout confined to a single professional identity. This paper analyzed the mediating effect of the improvement of medical professionals’ overall narrative competence in the formation of reciprocal work-family enrichment， and further proposed benefit-enhancing strategies at both individual and organizational levels， thereby improving medical professionals’ comprehensive capabilities and advancing high-quality development of hospitals.

As an extension of the central nervous system, the retina is the only tissue in the body that allows direct in vivo observation of both neural and vascular structures, offering a unique non-invasive window for the assessment of cerebral neurovascular diseases. Recent studies have shown that multimodal imaging techniques—such as fundus photography, optical coherence tomography(OCT), and OCT angiography(OCTA)—enable quantitative analysis of retinal indicators including vascular caliber, fractal dimension, retinal nerve fiber layer thickness, and microvascular density. These metrics can, to some extent, reflect the severity and progression risk of cerebrovascular and neurodegenerative diseases such as stroke, Alzheimer's disease, and Parkinson's disease. Consequently, retinal imaging holds promise as a powerful tool for early screening, risk stratification, and treatment monitoring. This article systematically reviews the application of retinal imaging technologies in the diagnosis and management of cerebral neurovascular disorders, with a particular focus on the important role of artificial intelligence(AI)-driven image analysis in enhancing screening efficiency, improving risk assessment accuracy, and promoting multidisciplinary collaborative care, thereby providing insights for clinical translation.

Sesquiterpenes are natural terpenes containing 15 carbon atoms. They are widely used in the perfume, pharmaceutical, and biofuel industries due to their remarkable biological activities. The traditional production of sesquiterpenes relies on chemical synthesis or plant extraction, which has the disadvantages of low yields and waste of resources. The construction of microbial cell factories for the efficient synthesis of sesquiterpenes by means of synthetic biology provides a new option. In recent years, with the development of metabolic engineering and synthetic biology, the heterologous synthesis of a variety of sesquiterpenes has been successfully achieved by metabolic engineering of the oleaginous yeast, Yarrowia lipolytica. In this paper, we review the research progress in the heterologous synthesis of different sesquiterpenes by Y. lipolytica, discuss the synthetic biology strategies commonly used in this field, and make an outlook on the research directions and engineering approaches to further enhance the sesquiterpene yield in this host. This paper provides a reference for strategies such as synergistic optimization of synthetic biology and metabolic engineering, enhanced precursors, and opens up new directions for the application of synthetic biology in green chemistry and sustainable production.

Objective To investigate the relationship between platelet distribution width(PDW)and coronary artery calcification(CAC)in overweight and obese populations.Methods Clinical and chest CT data of 10 838 subjects with overweight or obesity(body mass index[BMI]≥24 kg/m2)were retrospectively analyzed.The subjects were divided into CAC group(n=4 237)and non-CAC group(n=6 601)based on CAC scores obtained from chest CT.The relationship between PDW and CAC in overweight and obese populations was analyzed after controlling confounding variables.A threshold effect analysis was conducted using a two-stage logistic model to find the non-linear inflection point.Subgroup analyses and interaction tests were conducted to validate the stability of the relationship between PDW and CAC.Results Non-linear relationship was observed between PDW and CAC risk in overweight and obese populations.The risk of CAC decreased with the increase of PDW which ≤17.80％(OR=0.82),but increased with the increase of PDW(OR=1.04)which＞17.80％.Subgroup analysis showed that the relationship between PDW and CAC remained stable in subgroups of different genders,BMI(＜28 kg/m2,≥28 kg/m2)and hypertension(all P＞0.05).Compared with aged＜40 years or ≥60 years subgroups,under the same PDW,aged≥40 and＜60 years subgroups had higher risk of CAC(interaction P=0.015).Conclusion Nonlinear relationship existed between PDW and CAC in overweight and obese populations.Both excessively high and low PDW were risk factors of CAC.

Evidence-based public health, as the forefront of modern public health practice, has increasingly important in public health field. However, a significant gap remains between the available evidence and its practical application. Effectively disseminating and implementing evidence-based public health practice in real-world settings has become a key challenge in contemporary public health research. In this context, Implementation Science has emerged as a vital discipline. This paper explores the critical role of Implementation Science in public health, reviews the origins and core components of the Consolidated Framework for Implementation Research (CFIR), and analyzes the current application of CFIR in public health through bibliometric methods. Additionally, it discusses specific examples to further elucidate the steps involved in using the CFIR and its application contexts. The findings indicate that since 2015, research on CFIR in public health has progressively increased, showing a continuous upward trend. CFIR applications mainly address context-specific facilitators, health decision-making, barrier and facilitator identification, and community-based participatory evaluation, predominantly employing qualitative and mixed-methods research. This paper not only reviews and analyzes the current use of CFIR in public health but also provides a detailed discussion on its application. The goal is to offer valuable insights for the development of Implementation Science research within China's public health sector.

Objective To assess the intervention effect of nicotinamide mononucleotide (NMN) on the mouse model of hematotoxicity induced by subacute benzene exposure. Methods Benzene exposure and NMN intervention were adopted in a 2×2 factorial design, as benzene exposure and non-exposure, and NMN intervention and non-intervention. Male specific pathogen-free C57BL/6J mice were randomly assigned to negative control group, NMN control group, simple benzene exposure group and NMN intervention group, with 12 mice in each group. Benzene exposure of mice in simple benzene exposure group and NMN intervention group was conducted by dynamic inhalation of benzene at a concentration of 325 mg/m³ for six hours per day, five days per week for four weeks (28 days). Mice in the negative control and NMN control group inhaled clean air. During benzene exposure, mice in the NMN control group and NMN intervention group received NMN in drinking water at a dose of 300 mg/kg body weight. Peripheral blood samples of mice were collected for complete blood count analysis and calculation of composite inflammatory indices after 28 days. Results Interaction analysis showed that the counts of peripheral white blood cell, neutrophil, lymphocyte, and platelet of mice in the simple benzene exposure group were lower than those in the negative control group (all P<0.05). Neutrophil and platelet counts in the NMN intervention group were higher than those in the simple benzene exposure group (all P<0.05). The results of main effect analysis showed that the monocyte count of peripheral blood, systemic inflammatory index, systemic inflammatory response index, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio of mice in the benzene exposure group increased (all P<0.05), and the basophil count and lymphocyte/monocyte ratio decreased (all P<0.05), compared with the control group. Conclusion Oral NMN alleviates subacute benzene-induced decreases in peripheral neutrophil and platelet counts in mice. This protective effect may be related to the targeted intervention of NMN on mitochondrial energy metabolism disorder and oxidative damage induced by benzene exposure in male mice.
