Objective To investigate the prevalence, distribution characteristics, and influencing factors of mental health problems among the elderly, and to provide a scientific basis for policy-making.  Methods A convenience sampling method was used to investigate depression, anxiety, and cognitive function among permanent residents aged 65 and older at 59 mental health care sites for the elderly in Hubei Province. Multinomial logistic regression was employed to analyze influencing factors. Results The screening rates for depression, anxiety, and cognitive function at critical/high-risk levels among the elderly in Hubei Province were 9.7%, 5.4%, and 12.2%, respectively. Urban elderly had lower risks of depression and cognitive function at critical/high-risk levels compared to rural elderly (OR for critical depression = 0.640, P < 0.001; OR for high-risk depression = 0.595, P = 0.012; OR for critical cognitive function = 0.448, P < 0.001; OR for high-risk cognitive function = 0.188, P < 0.001). Six key population groups had higher risks of depression, anxiety, and cognitive function at critical/high-risk levels than others (OR for critical depression = 1.463, P < 0.001; OR for high-risk depression = 1.912, P < 0.001; OR for critical anxiety = 1.462, P < 0.001; OR for high-risk anxiety = 2.882, P < 0.001; OR for critical cognitive function = 1.381, P < 0.001; OR for high-risk cognitive function = 2.345, P < 0.001). A higher number of chronic diseases was associated with increased risks of critical and high-risk depression (OR for critical = 1.316, P < 0.001; OR for high-risk = 3.677, P < 0.001) and cognitive impairment (OR for critical depression = 1.316, P < 0.001; OR for high-risk depression = 3.677, P < 0.001; OR for critical anxiety = 1.512, P < 0.001; OR for high-risk anxiety = 1.801, P < 0.001). Conclusion It is recommended to expand mental health care sites in rural areas, improve the layout of mutual-support elderly care facilities, and explore sustainable models for rural elderly care. Efforts should also focus on enhancing social participation among the elderly through community-based activities, and strengthening cognitive screening and emotional regulation interventions, with particular attention to the mental health needs of older, isolated, and chronically ill individuals.

Background The association between occupational physical activity (OPA) and cardiometabolic risk factors remains controversial, potentially due to differences in the associations between OPA and various cardiometabolic indicators, as well as the lack of a clearly defined optimal OPA range for multiple-indicator synergistic benefits. Objective To investigate the relationship between OPA and cardiometabolic risk factors in individuals at high risk of cardiovascular disease (CVD) in Hubei Province, and to explore an optimal OPA range for multi-indicator improvements. Methods Data were derived from the Hubei Province dataset of the China Health Evaluation And Risk Reduction Through Nationwide Teamwork from 2015 to 2023, including 19028 high-risk CVD individuals. OPA (metabolic equivalent·h·d⁻¹, MET·h·d⁻¹) was assessed using the China Kadoorie Biobank physical activity questionnaire, anthropometric measurements (height, weight, waist circumference) and cardiometabolic indicators (blood pressure, fasting blood glucose, lipid profiles) were measured. Multivariate logistic regression was used to analyze the association between logOPA quartiles (Q1-Q4) and abnormal cardiometabolic indicators, while restricted cubic spline (RCS) models were employed to explore their dose-response relationships. Subgroup and interaction analyses were also conducted by gender. Results The median OPA of all participants was 12.86 MET·h·d⁻¹ (male: 14.40 MET·h·d⁻¹, female: 11.14 MET·h·d⁻¹). After adjusting for confounders, compared with the Q1 group, logOPA in the Q4 group was associated with 20% (OR=0.80, 95%CI: 0.72, 0.89), 14% (OR=0.86, 95%CI: 0.78, 0.96), and 13% (OR=0.87, 95%CI: 0.79, 0.95) reduction in the risk of abdominal obesity, low high-density lipoprotein cholesterol (HDL-C), and metabolic syndrome (MS), respectively, and 33% (OR=1.33, 95%CI: 1.18, 1.49), 33% (OR=1.33, 95%CI: 1.18, 1.50), and 38% (OR=1.38, 95%CI: 1.21, 1.57) increase in the risk of high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), and high non-HDL-C, respectively. Similar trends were observed in males and females, with significant positive associations of logOPA with high TC and high non-HDL-C in males (P_interaction<0.05). The risk of low HDL-C decreased rapidly when logOPA was more than 2.213 (OPA>9.14 MET·h·d⁻¹), showing an inverted L-shaped trend. The risk of high TC, high LDL-C, and high non-HDL-C increased beyond logOPA thresholds of 3.244, 2.476, and 3.377 (OPA >25.64, 11.89, and 29.28 MET·h·d⁻¹), respectively, showing a J-shaped trend. However, logOPA exhibited a U-shaped nonlinear dose-response relationship with blood pressure and fasting blood glucose abnormalities (P_non-linear<0.05) , with minimal risks at logOPA 2.969 and 2.372 (OPA of 19.47 and 10.72 MET·h·d⁻¹). Conclusion OPA exhibits heterogeneous dose-response patterns across cardiometabolic indicators. Integrating the inverted L-, J-, and U-shaped association patterns, we suggest an optimal OPA range of 9.14−25.64 MET·h·d⁻¹ for multiple cardiometabolic indicators in total individuals at high-risk of CVD, with ranges of 9.61−31.34 MET·h·d⁻¹ for males and 8.97−22.87 MET·h·d⁻¹ for females. These findings provide critical evidence for developing OPA interventions strategies targeting high-risk population for CVD.

IgA nephropathy（IgAN）is the most prevalent primary glomerulonephritis worldwide and exhibits a particularly high incidence in Asian populations.Despite advances in understanding its clinical and pathological features，the precise pathogenesis of IgAN remains incompletely elucidated.Emerging evidence highlights the complement lectin pathway as a critical contributor to IgAN progression，influencing both disease initiation and advancement.Key components of this pathway may serve as promising biomarkers for evaluating disease severity and prognosis，as well as potential therapeutic targets.This review focuses on the activation，regulation，and roles of diverse lectin pathway components in IgAN，aiming to deepen the understanding of the lectin pathway's contribution to IgAN pathogenesis and facilitating the identification of effective targeted therapies for this condition.

Objective:To explore the status quo of pediatric nurses' cognition of death education, and analyze its influencing factors, so as to provide experience and reference for carrying out death education in pediatric wards.Methods:In this study, 827 nurses from 15 children's hospitals in China were investigated by using the scale for evaluating the cognition of death education in medical staff prepared by Zhang Yan-gai, and the related factors affecting the cognition of death education were analyzed. SPSS 23.0 was used for independent-samples t-test and ANOVA analysis, and multiple regression equation was used to further analyze the relationship between the cognitive factors of death education in pediatric nurses. Results:The total score of death education cognition of pediatric nurses was (35.61±5.64) points, which was lower than the median score of 36 points. The degree of death education cognition of pediatric nurses was at the medium-low level. The results of correlation analysis showed that the professional title of nurses (regression coefficient: 0.064, P=0.045), the training demand for death education (regression coefficient: 0.300, P<0.001), and the way of understanding (regression coefficient: 0.018, P=0.003) were independent influencing factors of the death education cognition level of pediatric nurses. Conclusions:Pediatric nurse death education related theoretical knowledge should be improved through various professional trainings. The hospitals should include death education in pediatric nurse continuing education training plan to improve pediatric nurses' cognitive level of death education through a variety of ways and means, promote the application of death education activities carried out in pediatric ward in the hospice care, reduce deaths impact to nurse their own emotions, and alleviate parents' anxiety and painful experience, thereby improving medical satisfaction.

Objective:To analyze the expression of cell division cycle associated protein 5 (CDCA5) in pancreatic cancer tissues and its correlation with prognosis based on the bioinformatics.Methods:The RNA sequencing data (HTSeq-FPKM) and corresponding clinical information of 168 pancreatic cancer samples from January to December 2021 were downloaded from the Cancer Genome Atlas (TCGA) database, and the data of 179 pancreatic patients from January to December 2021 were downloaded from the GEPIA2 database, and 171 normal pancreatic tissues from TCGA and GTEx databases were simultaneously integrated. The relative expression level of CDCA5 mRNA in pancreatic cancer patients in GEPIA2 database and its relationship with overall survival (OS) and disease-free survival (DFS) were explored. Combined with the clinical data of the patients, univariate and multivariate Cox regression model analysis was used to analyze the factors influencing the OS of pancreatic cancer patients. Gene set enrichment analysis (GSEA) was performed to investigate the possibly involved signal pathways of CDCA5 in pancreatic cancer.Results:In the GEPIA2 database, the relative expression level of CDCA5 mRNA in pancreatic cancer tissues was higher than that in normal pancreatic tissues, and the difference was statistically significant ( P < 0.05). The pancreatic cancer patients were divided into the high CDCA5 mRNA expression group (89 cases) and the low CDCA5 mRNA expression group (89 cases) according to the median of relative expression level of CDCA5 mRNA (the case equal to the median value was not subgrouped). Survival analysis showed that patients with high CDCA5 mRNA expression had shorter OS ( P = 0.024) and DFS ( P = 0.025) compared with those with low CDCA5 mRNA expression. Multivariate Cox analysis showed that in TCGA database, N staging ( HR = 2.15, 95% CI 1.24-3.72, P = 0.006) and CDCA5 expression ( HR = 1.71, 95% CI 1.23-2.38, P = 0.001) were independent influencing factors of OS for pancreatic cancer patients. The results of GSEA enrichment analysis indicated that high CDCA5 mRNA expression was enriched in 13 biological pathways [all P < 0.05, false discovery rate (FDR) < 0.005] including cell cycle, DNA replication, homologous recombination, pyrimidine metabolism, mismatch repair, pentose phosphate pathway, glycolysis gluconeogenesis and p53. The expression of CDCA5 mRNA was positively correlated with the expressions of HK2, PKM, PGK1, ALDOA, EN01 and LDHA (all P < 0.05). Conclusions:CDCA5 is highly expressed in pancreatic cancer tissues and is associated with poor prognosis of patients, and it can be used as a prognostic marker for pancreatic cancer.

This article reviews the status quo, related reasons, influencing factors and interventions of unplanned readmission of renal transplant recipients for reference in clinical practice.

Objective:To investigate the effect of early external diaphragm pacing on the diaphragm function and prognosis of patients with mechanical ventilation.Methods:A total of 47 patients receiving invasive mechanical ventilation in the Emergency Intensive Care Unit of Hunan Provincial People's Hospital (The First Affiliated Hospital of Hunan Normal University) from October 2019 to July 2021 were selected and randomly divided into the treatment group ( n=23) and control group ( n=24). The patients in the control group received routine clinical treatment. On this basis, the treatment group received external diaphragm pacing treatment every day from the third day of mechanical ventilation until weaning, and was followed up to 30 days after discharge. The diaphragm thickness, diaphragm excursion, diaphragm thickening fraction, mechanical ventilation time, number of weaning failures, length of hospital stay and death toll were compared between the two groups. Results:Compared with the control group, the diaphragm thickness [(0.21±0.05) cm vs. (0.16±0.05) cm], diaphragm excursion [(1.38±0.37) cm vs. (1.11±0.48) cm], and diaphragm thickening fraction [26% (19%, 32%) vs. 18.5% (10.25%, 20%)] in the treatment group increased significantly (all P<0.05). The mechanical ventilation time was shorter in the treatment group [10 (7, 15) d vs. 13 (10.25, 19) d], and the difference was statistically significant ( P<0.05). There were no significant differences in the number of weaning failures (7 vs. 9), length of hospital stay [22 (15 , 30) d vs.. 24 (17.25, 34.25) d] and deaths (8 vs. 8) (all P>0.05). Conclusions:Early application of external diaphragm pacing can improve the diaphragm function of patients with mechanical ventilation, delay the decline in diaphragm function, increase diaphragm excursion and diaphragm thickening fraction, and shorten the mechanical ventilation time.
