Objective:To translate the English version of the Attitude Tool of Delirium (ATOD) into Chinese and test the reliability and validity of its application in Chinese nurses, and to provide an assessment tool for assessing nurses ′ attitudes towards delirium patients. Methods:After obtaining authorization from the source scale developer, the English version of the ATOD scale was translated, back-translated, expert-consulte, pre-surveyed and cross-culturally adapted according to the Brislin translation model. A questionnaire survey was conducted among 298 nurses with experience in caring for patients with delirium in three tertiary hospitals in Jiangsu Province using a convenience sampling method. The critical ratio value and correlation coefficient were used to analyze the scale items. Exploratory factor analysis was used to evaluate the structural validity of the scale, and experts were invited to evaluate the content validity of the scale. Cronbach α coefficient and test-retest reliability were used to evaluate the reliability of the scale. Results:The Chinese version of the ATOD scale contains 3 dimensions of cognitive attitudes, behavioral attitudes, and emotional attitudes toward patients with delirium, with a total of 23 entries. The Cronbach α coefficient for the entire scale was 0.896, with each dimension′s Cronbach α coefficient ranging from 0.614 to 0.912. The retest reliability of the scale was 0.868, with each dimension ′s retest reliability ranging from 0.603 to 0.927. Exploratory factor analysis extracted three eigenvalues with common factors greater than 1, and the cumulative variance contribution rate was 63.812%. Conclusions:The Chinese version of the ATOD scale has good reliability and validity, and can be used as an evaluation tool for evaluating nurses ′ attitudes towards delirium patients in China, so as to provide an effective basis for the formulation of corresponding interventions.

Objective:To explore the mediating effect of intrinsic motivation of nurses between empowering leadership and job performance, with the aim of providing a reference basis for managers to develop a scientific and effective intervention programme to improve nurses′ job performance.Methods:Convenience sampling method was used to select 1 213 clinical nurses from four tertiary general hospitals in Shandong Province, Henan Province, Yunnan Province, and Fujian Province from November to December 2023, and General Information Questionnaire, Empowering Leadership Scale, Intrinsic Motivation Scale, and Job Performance Scale were used to conduct a cross-sectional survey. AMOS26.0 software was used to test the mediating effect of intrinsic motivation of nurses between empowering leadership and job performance.Results:A total of 1 100 nurses completed the survey finally. Among them, there were 58 males and 1 042 females, 474 under 31 years old, 448 between 31-40 years old, and 178 over 40 years old.The total scores of the Empowering Leadership Scale, Intrinsic Motivation Scale, and Job Performance Scale were 49.44 ± 10.04, 82.35 ± 13.54 and 46.27 ± 6.20 in that order. Nurses' job performance were positive correlation with the empowered leadership and intrinsic motivation ( r=0.486, 0.703, both P<0.01), there was a positive correlation between nurse empowerment leadership and intrinsic motivation ( r=0.452, P<0.01). Nurses′ intrinsic motivation partially mediates the relationship between empowering leadership and job performance, accounting for 62.69% of the total effect. Conclusions:Intrinsic motivation of nurses is a mediating variable between empowered leadership and job performance. Nursing managers should focus on nurses' participation in autonomous decision-making to enhance nurses′ sense of competence and meaning at work, and mobilise their motivation to improve job performance.

Objective The monosaccharide composition of Abelmoschus Manihot Radix polysaccharide was identified and then we evaluated the therapeutic effect on slow transit constipation.Finally,the pharmacodynamic substances and molecular mechanisms in the polysaccharide from Abelmoschus Manihot Radix to improve slow transit constipation were explored by network pharmacology and molecular docking techniques.Methods The polysaccharide from Abelmoschus Manihot Radix has been prepared by aqueous-alcoholic precipitation and has been determined by HPAEC method;The mice model of slow transit constipation was made by sc loperamide(10 mg?kg-1)and the therapeutic effect for the treatment of constipation was evaluated by two indicators:fecal water content and small intestinal propulsion rate;Pathological changes in the colon tissue of STC mice were observed by HE.Immunohistochemical method was used to detect zonula occludens-1(ZO-1)and claudin-1 expression in colon tissue of STC mice;qRT-PCR method was used to detect mRNA expressions of AQP3,AQP4,TNF-α,IL-1β and IL-6 in each group;Network pharmacology and molecular docking technology were used to explore the potential targets and pathways of the polysaccharide from Abelmoschus Manihot Radix in treating slow transit constipation.Results The Polysaccharide from Abelmoschus Manihot Radix significantly increased fecal water content and intestinal propulsion rate in mice caused by slow transit constipation,decreased the expressions of AQP3,AQP4,TNF-α,IL-1β and IL-6 mRNA(P<0.01,P<0.001),protected the integrity of the colonic barrier in STC mice,and increased the protein expressions of ZO-1 and claudin-1 in colon tissues of STC mice.By network pharmacology,it was found that monosaccharides such as rhamnose,fucose and glucuronic acid could mainly act on key targets such as STAT3,JUN,CASP3,HSP90AA1,VEGFA and IL-1β and regulate the Inflammatory mediator regulation of TRP channels,EGFR tyrosine kinase inhibitor resistance and AGE-RAGE signaling pathway in diabetic complications to improve the symptoms of constipation in mice.Western blot results showed that intervention with polysaccharides from the roots of Solanum palmatum significantly reduced the expression of CASP3,VEGFA and IL-1β protein in the colon tissue of constipated mice.Conclusion The polysaccharide from Abelmoschus Manihot Radix can treat slow transit constipation through multi-component,multi-target and multi-pathway therapy.It provides a scientific basis for the further clinical application of Abelmoschus Manihot and drug development(National patent ZL202310894613.3.has been authorized)and it is expected to promote the efficient utilisation of resources from the non-medicinal parts of Abelmoschus Manihot.

Objective To test the reliability and validity of the Chinese version of the Nine-Item Avoidant/Restrictive Food Intake Disorder Scale (NIAS) in patients with inflammatory bowel disease (IBD). Methods Based on convenience sampling method, 304 patients from the Treatment Center for Inflammatory Bowel Disease of two Grade Ⅲ Level hospitals A in Jiangsu Province were selected as the research objects, and they were investigated by a general information questionnaire, NIAS, and the Satisfaction with Food-Related Life (SWFL). Item analysis (discrimination analysis, correlation coefficient) and reliability analysis of the total scale and subscales (Cronbach's α coefficient) were performed. Exploratory factor analysis, confirmatory factor analysis, criterion-related validity, convergent validity, and discriminant validity were used to test the validity of the scale. Results The Chinese version of NIAS contained 9 items, including 3 subscales of picky eating, appetite and fear; the confirmatory factor analysis indicated a good construct validity in 3-factor model[χ²/df=2.340, root mean square error of approximation (RMSEA)=0.078, standardized root mean square residual (SRMR)=0.046, incremental fit index (IFI)=0.969, comparative fit index (CFI)=0.969, normed fit index (NFI)=0.948, goodness of fit index (GFI)=0.951, the Tucker-Lewis index (TLI)=0.951]; the correlation coefficient between the total score of the Chinese version of NIAS and the SWFL scale was -0.353, indicating a strong correlation; the aggregated validity CR values for each dimension of the scale were 0.821 to 0.855, and the AVE values were 0.606 for appetite, 0.621 for picky eating, and 0.664 for fear. The total Cronbach's α coefficient of the Chinese version of the NIAS scale was 0.82, and the Cronbach's α coefficients for dimensions of picky eating, appetite and fear were 0.87, 0.71 and 0.92 respectively, indicating the Chinese version of the NIAS scale had good internal consistency and stability. Conclusion The Chinese version of the NIAS scale has good reliability and validity, and can be used to evaluate avoidant and restrictive food intake disorder behaviors in IBD patients.

Objective To investigate the correlation between the total CSVD burden and fundus vasculopathy,and evaluate significance of fundus vasculopathy for cognitive impairment in CSVD patients.Methods A total of 290 inpatients who taking physical examination in our department from May 2021 to August 2022 were consecutively recruited,and according to their score of CSVD,they were divided into group 0(129 cases),group 1(51 case),group 2(42 cases),group 3(44 cases),and group 4(24 cases).All the subjects underwent brain magnetic resonance imaging,fundus fluorescein angiography,and cognitive function assessment.The total CSVD burden and fundus vasculopathy were evaluated.The general clinical data,results of laboratory tests,fundus vascularization,and cognitive function were compared among the groups with different CSVD burden scores.Spearman correlation analysis and linear correlation analysis were used to explore the correlation between total CSVD burden score and fundus vascular disease.Results Significant differences were observed in terms of age,years of education,cerebral infarction/TIA,total cho-lesterol,LDL-C,creatinine,MoC A and MMSE scores,positive results of connectivity test,digit-symbol conversion test,Stroop colour-word interference test and verbal fluency test,values of CRAE,CRVE,AVR,Scheie grade,DWMH and PVWMH,enlarged perivascular space in the basal ganglia(BG-EPVS),lacunar infarct and cerebral microbleeds(CMB)in different CSVD total bur-den groups(P＜0.05,P＜0.01).Spearman correlation analysis showed that total CSVD burden was negatively correlated with CRAE and AVR(r=-0.655,P=0.000;r=-0.679,P=0.000),and positively with CRVE and Scheie grade(r=0.560,P=0.000;r=0.685,P=0.000).Multivari-ate linear analysis showed that the total CSVD burden after adjusting for relevant risk factors was significantly correlated with CRAE,CRVE,AVR and Scheie grades(P＜0.01).Conclusion Fun-dus vasculopathy is strongly associated with increased total CSVD burden,and it can be regarded as a valid predictor of CSVD-related cognitive impairment.

Objective To observe the effects of tetrandrine on the proliferation,migration,and invasion of melanoma cell B16,and to explore its effects on epithelial mesenchymal transition(EMT)and potential regulatory mechanisms.Methods(1)The proliferation of B16 cells was detected by CCK-8 assay after 0,2,4,6,8 and 10 μmol·L-1 of tetrandrine intervention for 24 and 48 hours.The colony formation ability of B16 cells was detected by plate clone formation assay after 1,2 and 4 μmol·L-1 of tetrandrine intervention;the migration and invasion ability of B16 cells was detected by cell scratch assay and Transwell invasion assay;the expressions of N-cadherin,Vimentin and E-cadherin related to EMT in B16 cells were detected by Western Blot assay.The mouse melanoma lung metastasis model was replicated by tail vein injection of B16 cells to observe the effects of tetrandrine(50 and 100 mg·kg-1)administered by gavage on the number of metastatic tumor nodules in the lungs of mice.(2)The CTD,SwissTargetPrediction and Similarity Ensemble Approach databases were used to predict the targets of tetrandrine;the GeneCards database was used to search for targets related to melanoma disease;the intersection of these two databases was taken as the potential target of tetrandrine for melanoma treatment.The intersected targets were imported into STRING database to construct protein-protein interaction(PPI)network and screen the core targets;the intersected targets were imported into DAVID database for GO function and KEGG pathway enrichment analysis;and molecular docking between tetrandrine and the core targets was verified by Autodock software.(3)In vivo experimental validation:after intervention of 1,2 and 4 μmol·L-1 tetrandrine,Western Blot method was used to detect the expression of the key pathway AKT/NF-κB/CREB pathway-related proteins;and AKT agonist SC79 was used to validate the replication experiments.Results(1)The IC50 of B16 cells intervened by tetrandrine was 4.273 and 4.085 μmol·L-1 at 24 and 48 hours.Compared with the control group,the colony forming ability,scratch healing rate and invasion rate of cells in the 1,2 and 4 μmol·L-1 tetrandrine group were all significantly reduced(P＜0.05,P＜0.01,P＜0.001);the expressions of cellular Vimentin and N-cadherin protein expressions were significantly down-regulated(P＜0.01,P＜0.001),and E-cadherin protein expression was significantly up-regulated(P＜0.01,P＜0.001).Compared with the model control group,the number of melanoma lung metastatic nodules was significantly reduced in the mice in the high-dose group of tetrandrine(P＜0.05).(2)A total of 60 potential targets were obtained for the treatment of melanoma with tetrandrine;core targets such as AKT1,TNF,CCND1,RELA,CASP9,CHUK,and CREBBP were further screened,among which AKT1 was the most strongly interacting target;the signaling pathways such as apoptosis,FoxO,TNF,PI3K-AKT,and NF-κB were mainly involved.The molecular docking showed that tetrandrine had strong binding activity with AKT1,TNF,RELA and other core targets.Compared with the control group,protein expressions of p-AKT/AKT,p-NF-κB p65/NF-κ B p65,and p-CREB/CREB were significantly down-regulated in the cells of the tetrandrine 1,2,and 4 μmol·L-1 groups(P＜0.05,P＜0.01);protein expressions of p-AKT and p-NF-κB p65 were significantly up-regulated in the cells of the SC79 group(P＜0.001).Compared with the SC79 group,protein expressions of p-AKT,p-NF-κB p65,and p-CREB were significantly down-regulated in the cells of the 2 μmol·L-1 tetrandrine+ SC79 group(P＜0.001).Conclusion Tetrandrine may inhibit the proliferation,migration,invasion and EMT of mouse melanoma by regulating the AKT/NF-κB/CREB pathway,and thus inhibit the lung metastasis of mouse melanoma.

【Objective】 To discuss the practice of emergency recruitment of blood donors through TikTok by shooting short videos, and evaluate the recruitment effect. 【Methods】 The completed short videos about blood donor emergency recruitment were released by major media official accounts on TikTok on New Year′s Day, May Day and National Day in 2022. Blood collection data within 10 days before and after the release were collected, and data within 7 days after the release were selected as the experimental group and the same period in last year as the control group to compare the blood collection units, donation frequency, gender and age of blood donors. 【Results】 The units of daily blood collection was the largest on day 1 after the release of TikTok short video, which was 3 times that of the previous day, and then decreased day by day, until to the same level as before the release on day 7. The daily blood collection, the proportion of first-time blood donors, donors aged 26 to 55 years old in the experimental group were all higher than those of the control group, but the proportion of blood donors aged 18 to 25 years old was lower than that of the control group. There was no significant difference in gender between the two groups. 【Conclusion】 Releasing short videos of blood donor emergency recruitment through TikTok, with fast dissemination and wild audience, can increase the blood inventory in a short time and is worthy of promotion.
