Objective To explore the effectiveness of safety management strategies and nursing quality control measures for in-hospital emergency transfers of patients with acute cerebral hemorrhage.Methods A total of 100 patients with acute cerebral hemorrhage were divided into control group(be-fore implementation,n=50)and observation group(after implementation,n=50)based on the tim-ing of implementation of the standard and measures.The preparation time for transfer,incidence of ad-verse events,personnel allocation for transfer,equipment completeness,changes in Glasgow Coma Scale(GCS)scores,and length of hospital stay were compared between the two groups.Results The prepa-ration time for transfer in the observation group was shorter than that of the control group[(15.2±3.5)min versus(23.7±5.8)min,P＜0.05];the incidence of adverse events was lower in the observation group than that in the control group(6.0％versus 22.0％,P＜0.05);personnel allocation complete-ness rate was reasonable in the observation group compared to that in the control group(68.0％versus 100％,P＜0.05);equipment completeness was higher in the observation group than that in the con-trol group(98.0％versus 82.0％,P＜0.05);GCS score was less in the observation group than that in the control group[(0.5±0.3)points versus(1.1±0.9)points,P＜0.05];the length of hospi-tal stay in the observation group was shorter than that in the control group[(14.5±3.2)days versus(18.3±4.1)days,P＜0.05].Conclusion Implementing standardized in-hospital emergency transfer safety management strategies and nursing quality control measures can improve the safety of pa-tient transfers,reduce occurrence of adverse events,and improve short-term prognosis for patients with acute cerebral hemorrhage.

Objective To explore the influencing factors of cognitive impairment in non-dialysis patients with chronic kidney disease(CKD).Methods A total of 60 hospitalized non-dialysis patients with CKD in the Department of Nephrology of Northern Jiangsu People's Hospital Affiliated to Yangzhou University from September 2022 to September 2023 were enrolled as research objects.According to the estimated glomerular filtration rate(eGFR),they were divided into stage 1 to 2 of CKD group[eGFR ≥60 mL/(min·1.73 m2)]with 23 cases,the stage 3 of CKD group[eGFR 30～＜60 mL/(min·1.73 m2)]with 20 cases,and stage 4 to 5 of CKD group[eGFR＜30 mL/(min·1.73 m2)]with 17 cases.The Montreal Cognitive Assessment Scale(MoCA)was used to evaluate the cognitive function of the patients.Basic data and common clinical laboratory in-dicators on hospital admission were collected to analyze the differences in cognitive function levels under different renal function statuses and to explore the influencing factors of cognitive impairment.Results The incidence rates of cognitive impairment in the stage 1 to 2 of CKD group,stage 3 of CKD group,and stage 4 to 5 of CKD group were 47.8％,85.0％,and 94.1％respectively,the median MoCA scored 26,24 and 20 respectively,with statistically significant between-group differ-ences(P＜0.05).Cognitive function was significantly negatively correlated with age(r=-0.634,P＜0.001),blood urea nitrogen(BUN)(r=-0.574,P＜0.001),serum creatinine(Cr)(r=-0.417,P＜0.001),cystatin C(Cys-C)(r=-0.327,P=0.011),serum β2-microglobulin(β2-MG)(r=-0.259,P=0.046),and N-terminal pro-brain natriuretic peptide(NT-proBNP)(r=-0.474,P＜0.001),and was significantly positively correlated with hemoglobin(HB)(r=0.401,P=0.001)and eGFR(r=0.485,P＜0.001).Multivariate Logistic regression analysis showed that age(P=0.006)and NT-proBNP(P=0.041)were influencing factors of cognitive im-pairment in non-dialysis patients with CKD.Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC),sensitivity,and specificity of age for prediction were 0.860,0.864 and 0.812 respectively,the AUC,sensitivity,and specificity of NT-proBNP for pre-diction were 0.808,0.795 and 0.875 respectively,and the combined prediction of age and NT-proBNP had an AUC,sensitivity,and specificity of 0.893,0.955,and 0.750,respectively.Conclusion As renal function deteriorates,the incidence rate and severity of cognitive impairment in non-dialysis patients with CKD tend to increase.Advanced age,renal function deterioration,high NT-proBNP level,and anemia are associated with the occurrence of cognitive impairment in non-di-alysis patients with CKD,among which age and NT-proBNP are influencing factors for cognitive im-pairment.

Objective: To analyze the impact of parental sports concept and behavior on physical activity in preschool children, so as to provide a foundation for future guidance on fostering childrens physical activity within the family context. Methods: From November to December 2020, a clustered convenience sampling method was employed to conduct surveys, and a total of 283 children were selectal from one kindergarten each in Beijing, Shenyang, and Xian. Participating children wore ActiGraph GT9X accelerometers continuously for one week to collect data on different intensity levels of physical activity. Physical Activity afterschool Questionnaire for Preschooler (P-PAQ) was utilized to assess parental sports concept and behavior. The gender differences in physical activity level and physical activity compliance rate were analyzed by using ttest, Mann-Whitney U test, and Chisquare test; and the relationship between parental exercise concepts and behaviors and physical activity of preschool children was analyzed using Spearman rank correlation analysis and multiple linear regression analysis. Results: Parental sports concept was significantly positively correlated with average daily moderatetovigorous physical activity (MVPA) and total physical activity (TPA) in children (r=0.12-0.16, P<0.05). Parental sports behavior was significantly positively correlated with childrens average daily TPA (r=0.25, P<0.05). Multiple linear regression revealed that parental sports concept was positively correlated with average daily MVPA and TPA in both boys and girls (B=0.65-0.83), while parental sports behavior only was positively correlated with boys average daily MVPA and TPA (B=0.24-0.25)(P<0.05). Conclusions Parental sports concept and behavior can impact physical activity levels in preschool children, exhibiting gender differences. Future guidance on physical activity in family upbringing should consider both parental sports concept and behavior, and pay attention to the influence of childrens gender.

[Abstract] [Objective] To investigate the therapeutic effect of platelet-rich plasma (PRP) subcutaneous injection combined with gypenosides (GPs) oral administration on BALB/c mouse psoriatic inflammation and explore its mechanism of action. [Methods] The 6-8 week-old female SPF BALB/c mice were randomly divided into five groups: control, model, PRP, GPs and PRP+GPs group, with 5 mice in each group. Imiquimod (IMQ) was used to induce psoriasis-like skin inflammation on the back of mice except the control group. The onset and severity of psoriasis-like inflammation in different treatment groups were evaluated by observing skin lesions, skin thickness and measuring PASI score. HE staining and Ki67 staining were used to evaluate the pathological changes and proliferation of keratinocytes in psoriasis-like skin lesions. Blood cell count, enzyme-linked immunosorbent assay and Western blot were used to explore the changes in circulating white blood cell count, cytokines IL-17A and TNF-α, and related signaling pathway proteins p-STAT3 and p-P38. [Results] At the end of the experiment (on day 6), scale scores of model, PRP, GPs and PRP+GPs group were 3.6±0.49, 1.8±0.75, 1.8±0.75, 1.2±0.40, respectively; the ratios of skin thickness (μm) were 0.86±0.18, 0.59±0.10, 0.56±0.07 and 0.42±0.09; PASI scores were 10.6±1.02, 4.0±0.63, 4.0±1.10 and 3.2±0.75. Compared with the model group, the number of scales (P<0.01), patch thickness (P<0.01) and PASI score decreased (P<0.0001) showed a certain therapeutic effect, and PRP+GPs group had the best effect. Pathological examination showed that both the epidermal layer thickness (P<0.01) and epidermal cell proliferation (P<0.05) decreased in all treatment groups; IL-17A expression levels were 9.02±2.54, 16.56±3.49, 10.01±1.83, 11.12±2.48 and 10.50±2.16, and TNF-α expression levels were 223.36±70.34, 377.36±58.47, 265.42±45.14, 262.94±33.29 and 268.94±26.80 respectively. The expression of skin tissue IL-17A (P<0.05) and TNF-α (P<0.05) decreased, along with the decreased expression of related signaling pathway proteins p-STAT3 and p-P38. [Conclusion] PRP combined with GPs can reduce the expression of IL-17A and TNF-α through the STAT3 and P38 signaling pathways, thereby alleviating inflammation and inhibiting the overproliferation of keratinocytes, thus improving psoriasis-like skin inflammation in BALB/c mice.

Objective To investigate the relationships of pre-radiotherapy body weight,gender,age,EBVDNA,hemoglobin,plasma albumin,and induction chemotherapy regimen with the changes of target area and lymph node volume in adaptive radiotherapy,so as to provide a reference for the timing and population selection of adaptive radiotherapy.Methods A retrospective analysis was conducted on 34 patients who received the first course of radiotherapy at Sun Yat-sen University Cancer Center from January 2022 to November 2022.All patients underwent CT scans again after 20 sessions of radiotherapy for developing the secondary radiotherapy plans.The body weight,gender,age,tumor stage,hemoglobin,plasma albumin,induction chemotherapy regimen,and EBVDNA were collected.Results The tumor volume reduction in the primary focus was more evident in patients with pre-treatment plasma albumin≥40 g/L than in those with pre-treatment plasma albumin<40 g/L(t=3.971,P=0.001),and in patients with pretreatment EBVDNA≤4000 copies/mL than in those with pretreatment EBVDNA>4000 copies/mL(t=4.080,P=0.001).Pearson analysis showed that GTVnx volume difference was positively correlated with pre-radiotherapy GTVnx volume(r=0.444,P=0.009),right parotid gland volume difference(r=0.737,P<0.001),left parotid gland volume difference(r=0.435,P=0.010),and hemoglobin(r=0.722,P<0.001).Conclusion The reduction in tumor volume during radiotherapy is more pronounced in nasopharyngeal cancer patients with normal plasma albumin level and those with pretreatment EBVDNA≤4000 copies/mL.The pre-radiotherapy treatment volume of primary focus,parotid gland volume change before and after radiotherapy,and pre-radiotherapy EBVDNA,hemoglobin and plasma albumin levels can be used to predict the degree of tumor volume shrinkage during radiotherapy,providing a reference for the selection of the timing of adaptive radiotherapy for nasopharyngeal carcinoma.

Objective To explore the features of sleep quality and its relationship with perceived stress and occupational stress in military personnel serving in high-altitude regions.Methods Cross-sectional study design was adopted in this study.In February 2023,self-designed demographic data questionnaire,Pittsburgh sleep quality index(PSQI),perceived stress scale(PSS-10)and job content questionnaire(JCQ)were applied to survey 3 784 soldiers from a unit stationing in plateau subjected by cluster sampling.Results The total score of PSQI was 5.37±2.78 in the participants,and the total score and the scores of each dimension of PSQI were significantly higher than the national norms for Chinese(P＜0.001).There were significant differences in PSQI scores among different age,length of military service,nationality,length of stationing in plateau,education level and family structure(P＜0.001).The low perceived stress group had significantly lower PSQI scores than the high perceived stress group(t=-12.108,P＜0.001).Regulatory effect analysis showed that the length of stationing in plateau,work autonomy,work psychological requirements,and social support in the work environment could modulate the relationship between perceived stress and sleep quality(t=8.326,-3.788,-2.145,-6.656,P＜0.05),and explained 14.6％,7.6％,7.0％and 7.9％of the variance of sleep quality,respectively.Conclusion The military personnel serving in high-altitude regions have a poor sleep quality.Age,time of military service,time of stationing in plateau,nationality,family structure,education level,perceived stress,and occupational stress are important factors affecting their sleep quality.The length of stationing in plateau time and occupational stress,can modulate the relationship between perceived stress and sleep quality.

Objective:To explore the effects of long non-coding RNA (lncRNA) FAM224A on the proliferation and migration of ovarian cancer cells by regulating the expression of miRNA-590-3p (miR-590-3p).Methods:Human ovarian cancer cell lines OC3, SKOV-3, HO-8910, A2780 and human normal ovarian epithelial cell line IOSE80 were selected, and the relative expression of FAM224A in each cell line was detected by real-time quantitative polymerase chain reaction (qRT-PCR). The cell line with the lowest relative expression level of FAM224A was screened for follow-up experiment. The cells were divided into FAM224A group (transfected with FAM224A mimic gene) and control group (transfected with control mimic gene). CCK-8 method and cell scratch test were used to detect the cell proliferation and migration ability of the two groups. The bioinformatics website LncBase v.2 predicted that the target gene that FAM224A might complementarily bind to was miR-590-3p. qRT-PCR was used to detect the relative expression levels of miR-590-3p and forkhead box protein A2 (FOXA2) mRNA, and the expressions of related proteins were detected by Western blot.Results:The relative expression levels of FAM224A in ovarian cancer cell lines OC3, SKOV-3, HO-8910, A2780 and normal ovarian epithelial cell line IOSE80 were 0.23±0.04, 0.65±0.05, 0.45±0.03, 0.63±0.08 and 1.02±0.11, respectively, and the difference was statistically significant ( F = 14.78, P < 0.01), and the cell line with the lowest relative expression level of FAM224A was OC3. The results of CCK-8 method showed that the proliferation ability of OC3 cells in the FAM224A group was lower than that in the control group on the 2nd, 3rd, 4th and 5th day of culture (all P < 0.05). The scratch healing rates of OC3 cells in the FAM224A group and the control group were (18.6±2.3)% and (71.7±7.2)%, respectively, and the difference was statistically significant ( t = 6.99, P < 0.01). The relative expression levels of FAM224A in OC3 cells in the FAM224A group and the control group was 12.36±1.45 and 1.14±0.24, respectively ( t = 13.08, P < 0.01); the relative expression levels of miR-590-3p were 0.19±0.06 and 1.04±0.20, respectively ( t = 4.01, P < 0.01); the relative expression levels of FOXA2 mRNA were 6.37±1.37 and 1.05±0.08, respectively ( t = 3.86, P < 0.01). Compared with the control group, the expression of FOXA2 protein in OC3 cells in the FAM224A group was increased, the expressions of cell proliferation protein cyclin-dependent kinase 2 (CDK2) and cyclin D3 were decreased, and the expression of cell migration protein Snail was decreased. Conclusions:FAM224A is low expressed in ovarian cancer cell lines. FAM224A reduces the proliferation and migration ability of ovarian cancer OC3 cells by inhibiting the expression of miR-590-3p.
