Objective To analyze the value of combined prediction of peripheral blood CD4+,CD3-CD16+CD56+,CD8+,CD19+for the risk of death in patients with Epstein-Barr virus-associated hemophagocytic syn-drome(EBV-HLH).Methods A total of 84 patients with EBV-HLH who were treated in Beijing Friendship Hospital Affiliated to Capital Medical University and Peking University First Hospital from May 2021 to A-pril 2023 were selected and divided into a death group(17 cases)and a survival group(67 cases)according to their survival outcomes within 6 months.The general information and peripheral blood T lymphocyte subsets of the two groups were compared,multivariate Logistic regression analysis was conducted to investigate the influencing factors of death in EBV-HLH patients,and receiver operating characteristic(ROC)curve was used to evaluate the predictive value of peripheral blood T lymphocyte subsets on death in EBV-HLH patients.Results The platelet count,hemoglobin,CD4+and CD3-CD16+CD56+levels in the death group were lower than those in the survival group,while the levels of CD8+and CD19+were higher than those in the survival group(P＜0.05).Multivariate Logistic regression analysis showed that platelet count,hemoglobin,CD4+,and CD3-CD16+CD56+were all independent protective factors for the death of EBV-HLH patients,while CD8+and CD19+were independent risk factors for the death of EBV-HLH patients(P＜0.05).The ROC curve results showed that the area under the curve of combined prediction of CD4+,CD8+,CD19+,CD3 CD16+CD56+for death in EBV-HLH patients was 0.923,with sensitivity and specificity of 94.12％and 80.60％,respectively,which were significantly higher than those predicted by each individual indicator(P＜0.05).Conclusion The abnormal expression of CD4+,CD3-CD16+CD56+,CD8+,and CD19+in peripheral blood of EBV-HLH patients is associated with their survival outcomes,and the combined prediction of CD4+,CD3-CD16+CD56+,CD8+,and CD19+has high reference value for predicting patients'death.

Objective:To explore the longitudinal trajectory of sleep disorders and their influencing factors in newly diagnosed breast cancer patients, and provide theoretical basis for formulating intervention measures to improve sleep quality of breast cancer patients.Methods:A longitudinal study was conducted using convenience sampling to select newly diagnosed breast cancer patients from Shandong Provincial Third Hospital and Shandong First Medical University Affiliated Provincial Hospital from April 2023 to June 2024. General information questionnaires, the Pittsburgh Sleep Quality Index (PSQI), the Concerns About Recurrence Scale (CARS), and the Distress Disclosure Index (DDI) were used for the survey. The Kruskal-Wallis H test and generalized estimating equation models were used to examine sleep disorders and their influencing factors. Results:A total of 473 valid questionnaires were collected. Among the 473 newly diagnosed breast cancer patients, 435 were female and 38 were male, aged (49.5 ± 11.0) years old. The CARS score at admission was (3.00 ± 1.12) points, with concerns about death (0.71 ± 0.67) points and concerns about female characteristics (0.81 ± 0.72) points. The DDI score at admission was (27.00 ± 10.03) points. The PSQI scores at admission, discharge, and one month after discharge were (15.34 ± 3.05), (12.12 ± 3.01), and (10.13 ± 1.78) points, respectively, the difference was statistically significant ( H =33.19, P<0.05). The PSQI scores at these three time points were positively correlated with the CARS score and concerns about death and female characteristics ( r values were 0.42-0.79, all P<0.05), and negatively correlated with the DDI score ( r =-0.41, -0.37, -0.31, all P<0.05). The generalized estimating equation model showed that female gender ( β=1.35, 95% CI 0.27-2.30), education level of junior high school or below ( β=1.89, 95% CI 0.24-3.19), severe pain ( β=1.72, 95% CI 0.32-3.12), moderate pain ( β=2.51, 95% CI 0.37-4.66), invasive special cancer ( β=2.57, 95% CI 1.67-4.07), invasive non-special cancer ( β=2.11, 95% CI 1.98-3.12), partial understanding of the condition ( β=1.91, 95% CI 1.23-3.01), concerns about death ( β=1.61, 95% CI 0.17-2.78), and concerns about femininity ( β=1.34, 95% CI 0.37-2.15) positively predicted the sleep quality index in newly diagnosed breast cancer patients (all P<0.05). Non-invasive cancer ( β=-3.82, 95% CI -6.79--3.36), lack of understanding of the condition ( β=-3.96, 95% CI -7.09--4.62), and DDI score ( β=-1.45, 95% CI -2.14--0.15) negatively predicted the sleep quality index (all P<0.05). Conclusions:The overall sleep quality of newly diagnosed breast cancer patients is low, with the lowest at admission and gradual improvement at discharge and one month after discharge. Medical staff should pay attention to high-risk patients who are female, have lower education levels, higher pain scores, poorer pathological types, and partial understanding of their condition.

Objective To construct an animal model of post-stroke depression(PSD)based on the theory of"depression,stasis,phlegm",with the aim of developing and validating an objective assessment system.Methods Rats were divided randomly into five groups:control,depression,stroke,PSD,and Baishile decoction groups.A PSD syndrome-based animal model was established in rats using a combination of middle cerebral artery occlusion(MCAO)and chronic unpredictable mild stress(CUMS)."Depression,stasis,phlegm"were then evaluated in the model rats using the Morris water maze,open field,forced swimming,and sucrose preference tests,and by detection of neurotransmitter levels,brain tissue pathology,tongue and forepaw color RGB values,and blood rheology.Results PSD rats exhibited significantly shorter target quadrant dwelling times,platform crossings,and climbing and rearing frequencies,a significantly lower sucrose preference,and a significantly higher immobility time in the forced swim test compared with control rats.Hematoxylin and eosin and Nissl staining revealed brain tissue damage in PSD rats.Serum and cerebrospinal fluid levels of 5-hydroxytryptamine(5-HT)were significantly decreased,glutamate levels were significantly increased,and tongue and forepaw RGB values were all decreased.Blood rheology showed a hypercoagulable state and blood lipid metabolism-related indicators were significantly abnormal.Rats in the Baishile decoction group showed significant improvements compared with the PSD group,including increased target quadrant dwelling times,number of platform crossings,and climbing and rearing frequencies,increased sucrose preference,decreased immobility time in the forced swim test,improved brain tissue pathology,increased serum and cerebrospinal fluid levels of 5-HT,decreased glutamate levels,increased tongue and claw RGB values,and varying degrees of improvement in blood rheology and blood lipid metabolism-related indicators.Conclusions The combination of MCAO and CUMS successfully established a syndrome-based animal model of PSD exhibiting the characteristics of"depression,stasis,phlegm",with corresponding objective assessment criteria.

Objective To analyze the influence of Dapagliflozin on ventricular remodeling,soluble suppression of tumorigenicity-2(sST2)and brain natriuretic peptide(BNP)in patients with elderly ST-segment elevation myocardial infarction(STEMI)complicated with type 2 diabetes mellitus(T2DM)after percutaneous coronary intervention(PCI).Methods From April 2021 to March 2023,118 elderly patients with STEMI complicated with T2DM treated by PCI were selected from People's Hospital of Hengshui.They were divided into conventional hypoglycemic therapy control(Con,n=59)group and conventional hypoglycemic therapy combined with Dapagliflozin(Dap,n=59)group according to the treatment strategy.All the participants were treated for 24 weeks.The general data,biochemical indexes,BNP,N-terminal pro-B-type natriuretic peptide(NT-proBNP),soluble growth stimulating expression factor 2(sST2)and lipoprotein-associated phospholipase A2(LP-PLA2),left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and left ventricular mass index(LVMI)were compared between the two groups.Results After 24 weeks of treatment,the BNP,NT-proBNP,fasting plasma glucose(FPG),2 h postprandial blood glucose(2 hPG),glycosylated hemoglobin(HbA1c),LVEDD,LVESD,LVMI,serum sST2 and LP-PLA2 were lower in Dap group than in Con group(P<0.05),while the LVEF was higher in Dap group than in Con group(P<0.05).The total incidence rate of major adverse cardiovascular events was significantly lower in Dap group than in Con group(P<0.05).The incidence rates of adverse drug reactions were 6.78%and 5.08%in the two groups respectively(P>0.05).Conclusions Dapagliflozin can improve the cardiac function and glucose metabolism status in elderly patients with STEMI and T2DM after PCI,and alleviate the ventricular remodeling,with good safety.

Objective:To investigate the correlation between the density and volume of left atrial-epicardial adipose tissue(LA-EAT)and the occurrence and severity of atrial fibrillation(AF)in elderly patients.Methods:This was a retrospective case-control study.A total of 197 elderly patients with AF and 82 patients with sinus rhythm who were hospitalized in the Department of Cardiology and Geriatric Cardiology of the First Affiliated Hospital of Nanjing Medical University from June 2023 to July 2024.were selected.The AF group was further divided into paroxysmal AF(PAF)subgroup(111 cases)and persistent AF(PeAF)subgroup(86 cases). The density and volume of LA-EAT in all patients were meansured by coronary artery enhanced CT or left atrial enhanced CT.The differences in LA-EAT density, volume and related data among the 3 groups were compared, and their relationship with different severity of senile AF was analyzed.Logistic regression was used to analyze whether LA-EAT density and volume were risk factors for senile AF.The predictive value of LA-EAT density and volume for AF in the elderly was compared throuh restricted cubic spline analysis.Results:The average LA-EAT density in the sinus rhythm group, PAF group and PeAF group was -82.75(-87.15, -79.63), -81.70(-85.55, -75.85)and -80.45(-83.40, -76.10)HU, respectively; the standard deviation of density was 34.70(31.93, 36.28), 36.20(34.30, 37.65)and 35.45(33.63, 37.28)HU, respectively; the LA-EAT volume was 23 483.40(13 964.10, 31 645.53), 25 112.20(18 479.10, 36 917.50)and 37 836.50(25 933.80, 45 537.90)mm 3, respectively.The LA-EAT density and volume in the PAF group and PeAF group were higher than those in the sinus rhythm group(all P<0.05). The LA-EAT volume in the PeAF group was greater than that in the PAF group( P<0.001), but there was no significant difference in LA-EAT density between the two groups( P>0.05). Multivariate logistic regression analysis showed that LA-EAT density and volume, left atrial diameter(LAD)and body mass index(BMI)were the independent risk factors for AF in the elderly( P<0.05). Conclusions:LA-EAT density and volume are significantly correlated with occurrence of senile AF, and show a positive dose-response relationship.LA-EAT volume is significantly related to the severity of AF( P<0.05), while the density is not significantly related to it( P>0.05).

Objective To analyze and clarify the concept of family communication collective efficacy in hospitalized patients.Methods A systematic search was conducted in databases including China National Knowledge Infrastructure(CNKI),VIP Database,WanFang Database,PubMed Database and Web of Science(WOS)for studies related to family communication efficacy.The search timeframe spanned from the inception of each database to December 2024.Rodgers'evolutionary concept analysis method was applied to analyze the retrieved literature.Results A total of 40 articles were included.The analysis shows that the evolution process of the concept of family collective communication efficacy in hospitalized patients was introduced,encompassing the evolution of the family communication concept and the intersection and integration of family systems theory and collective efficacy theory.Family communication collective efficacy in hospitalized patients was characterized by four attributes:shared beliefs,emotional support,role allocation and coordination,and an integrated communication system.Its antecedents included factors such as sources of efficacy information,family member characteristics,and family team characteristics.The consequences were observed at three levels:individual,family,and healthcare system,including manifesting as bidirectional influences on individual health outcomes,family functioning,and healthcare quality improvement.Conclusions The core attributes of family communication collective efficacy in hospitalized patients were clarified through concept analysis.In the future,localized assessment tools should be developed based on these attributes to facilitate the implementation and evaluation of interventions aimed at enhancing family communication collective efficacy.

Objective To develop a postoperative precision nursing program for children with obstructive sleep apnea-hypopnea syndrome(OSAHS),so as to provide references for the improvement of nursing quality for children with OSAHS.Methods Literature in precision nursing for children with OSAHS was systematically reviewed and summarised based on precision nursing theory and a postoperative precision nursing program was drafted.Using the Delphi's Method,two rounds of expert consultation were conducted and the postoperative precision nursing program for children with OSAHS was revised and finalised.Results The response rates of the two rounds of expert consultation were 100.00%with the expert authority coefficient of 0.875.The Kendall coefficient of concordance(W)of levels 1,2 and 3 indices in the second round of expert consultation were 0.289,0.203,0.187,respectively(all P<0.01).The importance score of each inclicator ranged from 4.50～4.94.The coefficient of variations for the three-level indices ranged from 0.05 to 0.21.The finalised program composed 8 level-1 indices(postoperative position assessment,intervention,prevention and care of bleeding,maintaining postoperative airway patency,postoperative nausea and vomiting care,postoperative pain assessment and care,dietary care,complication prevention and care,discharge guidance),16 level-2 indices,and 22 level-3 indices.Conclusion The postoperative precision nursing program for the children with OSAHS is scientific,innovative and applicable.It provides clinical references for nursing of the children with OSAHS.

Objective The aim of this study was to explore the predictive value of the systemic inflammatory immune nutri-tion score(SIINS)for the prognosis of immunotherapy for advanced gastric cancer.Methods A retrospective analysis was conducted on the clinical data of 202 patients with advanced gastric cancer who received treatment with programmed death-1(PD-1)inhibitors at the Harbin Medical University Cancer Hospital from October 2018 to July 2022.The LASSO regression analysis was used to screen prognostic indicators,construct SIINS indicator,determine the optimal cutoff value for predicting prognosis using subject operating characteristic curves,and divide patients into the high SIINS and low SIINS groups.Independent prognostic factors for overall survival(OS)were determined using univariate and multivariate Cox regression analyses.Results Four indicators,including lymphocyte count,lactate dehydrogenase,and neutrophil lymphocytes,were selected to construct the SIINS index.The prognosis of patients in the high SIINS group was significantly lower than that in the low SIINS group(P<0.05).The results of the multifactorial Cox regression a-nalysis showed that the Eastern Cooperative Oncology Group(ECOG)score,Geriatric Nutritional Risk Index(GNRI),SIINS,treatment regimen,and number of treatment lines(P<0.05)could serve as the independent predictive prognosis of immunotherapy for advanced gastric cancer.Conclusion SIINS can predict the prognosis of patients with advanced gastric cancer treated with PD-1 inhibitors.
