Objective:To summarize medication safety assessment tools for clinical nurses both domestically and internationally.Methods:Guided by the Joanna Briggs Institute (JBI) scoping review methodology, a systematic search was conducted across CINAHL, Embase, PubMed, Web of Science, SinoMed, China National Knowledge Infrastructure, and WanFang Data. The search period was from the establishment of database to January 1, 2025. Medication safety assessment tools for clinical nurses were extracted, relevant content was systematically analyzed, and the retrieval results were reported in a standardized manner.Results:A total of 28 studies were included, involving 15 medication safety assessment tools for clinical nurses. Assessment methods employed multidimensional and graded self-assessment formats. Based on evaluation perspectives, these tools were categorized into six types, including operational standardization monitoring, cognitive bias calibration, environmental stress testing, capability threshold identification, reporting barrier analysis, and medication information systems. The assessment tools had high reliability and validity, multiple types, and diverse evaluation perspectives.Conclusions:Researchers should carefully select and use assessment tools based on research characteristics. It is necessary to enhance the autonomy of nursing research on medication safety, develop comprehensive and accurate clinical nurse medication safety assessment tools that are adapted to China's clinical context, and promote the improvement of nurse medication safety.

Objective:To investigate the differential impact of ultra-high-resolution photon-counting detector CT (UHR PCD-CT) and energy-integrating detector CT (EID-CT) on image quality and calcified plaque-induced luminal stenosis in coronary CT angiography (CCTA).Methods:This retrospective analysis was conducted on patients who underwent both EID-CT and UHR PCD-CT CCTA at the Geriatric Hospital of Nanjing Medical University between January 2021 and November 2024. A total of 141 patients were included in the study, within 46 patients having scans within a 12-month interval. Image quality of all coronary artery segments was subjectively evaluated. Patients with paired scans (interval≤12 months) were included for calcified plaque analysis. Subjective visualization of calcified plaques evaluated. The blooming artifact was calculated as an objective evaluation index for assessing the calcified plaques. Additionally, the degree of coronary artery lumen stenosis resulting from calcified plaques was assessed, along with the measurement of plaque volume and the Agatston score. Changes in lumen stenosis between the two scans were also evaluated. The Wilcoxon signed-rank test was used to compare the subjective scores of coronary artery image quality and calcified plaques between the two groups, and paired-sample t-tests were used to compare the blooming artifact and lumen stenosis degree. Results:The PCD-CT image quality score was significantly higher than that of EID-CT [PCD-CT : 5 (4,5), EID-CT: 4 (4,5); Z=-21.38, P<0.001]. Compared to EID-CT, PCD-CT reduced the blooming artifact (PCD-CT: 38.88%±9.09%, EID-CT: 50.11%±11.52%; t=-12.97, P<0.001), significantly improving the subjective score for visualization of calcified plaques [PCD-CT: 5 (4,5), EID-CT: 3 (2,3); Z=-9.68, P<0.001], and the measured lumen stenosis was notably lower in PCD-CT(PCD-CT:34.88%±18.20%, EID-CT:45.31%±23.42%; t=-9.93, P<0.001). Among 129 analyzed calcified plaques, luminal stenosis was reduced on PCD-CT in 110 plaques (85.3%) and increased in 19 (14.7%), including 4 plaques that had unclear boundaries with the adjacent lumen in EID-CT CCTA images, making the stenosis difficult to assess. Conclusion:Compared to EID-CT, UHR PCD-CT for CCTA significantly improves coronary artery image quality, provides clearer visualization of calcified plaques and adjacent lumen details, and it can reduce the overestimation of coronary artery caleified plaque stenosis.

Objective:To identify the serotype and genotype characteristics of the first cluster infection of Brucella in Nujiang Lisu Autonomous Prefecture of Yunnan Province. Methods:The information of seven suspected cluster brucellosis cases reported in Lanping County, Nujiang Lisu Autonomous Prefecture in April 2023 were collected, blood samples were collected, and the strains were isolated and cultured. Serological methods were employed for brucellosis diagnosis, bacterial species identification was performed using BCSP31-PCR and AMOS-PCR. Multilocus locus variable-number tandem repeat analysis (MLVA) was conducted for strain genotyping, followed by phylogenetic analysis comparing the strains with those from other regions of China.Results:All seven cases were diagnosed with brucellosis, they were all villagers from the same village and had daily contact with sheeps. Four suspected Brucella strains were isolated, identified as Brucella melitensis biotype by BCSP31-PCR and AMOS-PCR. The four isolated strains exhibited identical MLVA-16 genotype, with MLVA-8 genotype 42 and MLVA-11 genotype 180, belonging to the Eastern Mediterranean lineage. Compared with the MLVA-16 of the isolated strains from other regions of China, the four isolated strains formed an independent cluster. Conclusion:The first cluster infection of Brucella in Nujiang Lisu Autonomous Prefecture of Yunnan Province is caused by Brucella melitensis biotype, and the four isolated strains have showed unique MLVA genotype.

Objective:To investigate the effect of subacute exposure of Di(2-ethylhexyl)phthalate(DEHP)on endometrial decidualization and early pregnancy miscarriage in mice.Methods:CD1 mice were orally administrated with 300(low-dose group),1000(medium-dose group),or 3000 mg·kg-1·d-1 DEHP(1/10 LD50,high-dose group)for 28 days,respectively.An early natural pregnancy model and an artificially induced decidualization model were established.The uterine tissues were collected on D7 of natural pregnancy and D8 of artificially induced decidualization,respectively.The effects of a subacute exposure to DEHP on the decidualization of mice were detected by HE staining,Masson staining,TUNEL assay,and Western blotting.A model of spontaneous abortion was constructed in mice after subacute exposure to 300 mg·kg-1·d-1 DEHP,and the effect of impaired decidualization on pregnancy was investigated by observing the pregnancy outcome on the 10th day of gestation.Results:Compared with the control group,the conception rate was significantly decreased in the high-dose DEHP subacute exposure group(P＜0.05).HE staining showed that,compared with the control group,the decidual stromal cells in the low-and medium-dose exposure groups were disorganized,the nuclei of the cells were irregular,the cytoplasmic staining was uneven,and the number of polymorphonuclear cells was significantly reduced.Masson staining showed that compared with the control group,the collagen fibers in the decidua region of the DEHP low-dose group and the medium-dose group were more distributed,more abundant and more disorderly.TUNEL assay showed increased apoptosis in the decidua area compared to the control group.Western blotting showed that the expression of BMP2,a marker molecule for endometrial decidualization,was significantly reduced(P＜0.05 or P＜0.01).The abortion rate and embryo resorption rate were increased,and the number of embryos,uterine wet weight,uterine area and placenta wet weight were decreased in DEHP low-dose group compared to the control group stimulated by mifepristone,an abortifacient drug(P＜0.05 or P＜0.01).Conclusion:Subacute exposure to DEHP leads to impaired endometrial decidualization during early pregnancy and exacerbates the risk of adverse pregnancy outcomes in mice.

Objective:To explore the experience of self-management dilemma ofadults with emerging ankylosing spondylitis, and to provide reference for the construction of self-management intervention strategies for emerging adults with ankylosing spondylitis.Methods:Descriptive phenomenology was used to conduct in-depth interviews with 14 adults with emerging ankylosing spondylitis in the Rheumatology and Immunology Department of Drum Tower Hospital Affiliated to Medical College of Nanjing University from August 2022 to March 2023. The interview data were analyzed by Colaizzi′s seven-step analysis method.Results:A total of 14 patients completed the interview,10 males, 4 females, aged 21-30 years. In adults with emerging ankylosing spondylitis, there were dilemmas of role maladjustment and disease management disorder, including role maladjustment of disease management and social role maladjustment. Barriers to disease management included weak self-management awareness, insufficient support for self-management information, inadequate self-management skills, and poor compliance with self-management behaviors.Conclusions:The role adaptation and self-management ability of adults with emerging ankylosing spondylitis are seriously inadequate. It is urgent to construct health management strategies for adults with emerging ankylosing spondylitis to help them improve the level of role adaptation and disease management.

Transcatheter arterial chemoembolization (TACE) is recommended by domestic and international guidelines for the treatment of patients with unresectable hepatocellular carcinoma (uHCC), and it is one of the most common treatment methods for patients with uHCC. The chemotherapy drugs commonly used in TACE for HCC include epirubicin, cisplatin, and fluorouracil, while it is still unclear which chemotherapy drug has a better clinical effect. This article summarizes the studies of different TACE regimens using different chemotherapy drugs in the treatment of patients with uHCC in the recent five years. TACE combined with sorafenib can significantly improve the survival of patients with advanced HCC and has been recommended for the treatment of such patients by Chinese Society of Clinical Oncology guidelines, and the efficacy of TACE combined with other tyrosine kinase inhibitors (TKI) has become a research hotspot. Studies have shown that compared with TACE combined with sorafenib in the treatment of patients with advanced HCC, TACE combined with lenvatinib can achieve a significantly longer progression-free survival time and a tendency of increase in median overall survival time. However, due to the variation of target receptors or downstream signals, resistance to molecular-targeted agents is still a challenging problem. TKI combined with immune checkpoint inhibitors may be a promising strategy for the treatment of patients with uHCC. Some studies suggest that triple therapy using TACE combined with TKIs and anti-PD-1/PD-L1 monoclonal antibody has better efficacy in improving the survival of patients with uHCC. This article reviews the studies of the efficacy and safety of TACE combined with targeted agents and TACE combined with anti-PD-1/PD-L1 monoclonal antibody in the treatment of patients with uHCC in the recent five years.

Gut dysbiosis,a well-known risk factor to triggers the progression of Alzheimer's disease(AD),is strongly associated with metabolic disturbance.Trimethylamine N-oxide(TMAO),produced in the dietary choline metabolism,has been found to accelerate neurodegeneration in AD pathology.In this study,the cognitive function and gut microbiota of TgCRND8(Tg)mice of different ages were evaluated by Morris water maze task(MWMT)and 16S rRNA sequencing,respectively.Young pseudo germ-free(PGF)Tg mice that received faecal microbiota transplants from aged Tg mice and wild-type(WT)mice were selected to determine the role of the gut microbiota in the process of neuropathology.Excessive choline treatment for Tg mice was used to investigate the role of abnormal choline metabolism on the cognitive functions.Our results showed that gut dysbiosis,neuroinflammation response,Aβ deposition,tau hyper-phosphorylation,TMAO overproduction and cyclin-dependent kinase 5(CDK5)/transcription 3(STAT3)activation occurred in Tg mice age-dependently.Disordered microbiota of aged Tg mice accelerated AD pathology in young Tg mice,with the activation of CDK5/STAT3 signaling in the brains.On the contrary,faecal microbiota transplantation from WT mice alleviated the cognitive deficits,attenuated neuro-inflammation,Aβ deposition,tau hyperphosphorylation,TMAO overproduction and suppressed CDK5/STAT3 pathway activation in Tg mice.Moreover,excessive choline treatment was also shown to aggravate the cognitive deficits,Aβ deposition,neuroinflammation and CDK5/STAT3 pathway activation.These findings provide a novel insight into the interaction between gut dysbiosis and AD progression,clarifying the important roles of gut microbiota-derived substances such as TMAO in AD neuropathology.
