Objective To explore potential categories of post-stroke depression in acute-phase stroke patients and its correlation with the degree of neurological deficits,and to provide references for healthcare professionals in developing targeted interventions.Methods Using convenience sampling,patients with acute stroke who were hospitalized in neurological ward of 2 tertiary general hospitals in Henan Province from January to April 2024 were selected as the survey participants.The investigation was conducted using the General Information Questionnaire,the National Institute of Health Stroke Scale,and the Patient Health Questionnaire-9.The correlation between potential categories of post-stroke depression and the degree of neurological deficit was analysed using unordered multiclassified logistic regression.Results Post-stroke depression score was 10.22±3.61 in 193 acute-phase stroke patients,and post-stroke depression could be categorized into 3 potential categories,namely"low depressive symptoms"(44.6％),"melancholic depression"(15.0％),and"atypical depression"(40.4％).There was a significant difference in the degree of neurological deficits(H=38.074,P＜0.001).Compared with severe neurological deficits,patients with mild deficits were more likely to be categorized as"melancholic depression"(OR=0.016,P=0.001)and"atypical depression"(OR=0.040,P＜0.001),and patients with moderate deficits were more likely to be classified as"atypical depression"(OR=0.085,P=0.001).Conclusion Post-stroke depression in acute-phase stroke patients has obvious categorization characteristics,and it is recommended that healthcare professionals should pay more attention to patients with different degrees of neurological deficits and adopt targeted interventions according to the different categories of post-stroke depression in order to alleviate their depressive symptoms.

Objective To understand the changing profiles of antimicrobial susceptibility of the bacterial strains isolated from patients at Liuzhou Workers'Hospital in Guangxi from 2020 to 2022.Methods The bacteria were isolated,identified,and underwent antimicrobial susceptibility testing using VITEK 2 Compact,disk diffusion method,or E-test.The results were interpreted according to the breakpoints recommended by CLSI M100 32nd Edition in 2022.The data were analyzed using WHONET 5.6 software.Results A total of 26 254 nonduplicate strains were collected from 2020 to 2022,including Gram-positive bacteria(27.9％)and gram-negative bacteria(72.1％).The prevalence of methicillin-resistant strains was 20.0％in SS.aureus(MRSA),and 72.2％in coagulase-negative Staphylococcus(MRCNS).Methicillin-resistant staphylococcal strains were more resistant to most antimicrobial agents than methicillin-susceptible strains(MSSA and MSCNS).None of the staphylococcal strains was resistant to vancomycin,linezolid or tigecycline.Enterococcus faecium strains showed higher resistance rates to most antimicrobial agents than Enterococcus faecalis.None of enterococcal strains was resistant to vancomycin.A few enterococcal strains were resistant to linezolid.Overall,691 strains of the non-meningitis Streptococcus pneumoniae were isolated from children and 123 strains were isolated from adults.The prevalence of penicillin-resistant SS.pneumoniae(PRSP)was 0.4％in the strains from children and 1.6％in the strains from adults.None of S.pneumoniae strains was intermediate to penicillin.The prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKpn)was 1.2％,1.2％,and 13.8％in 2020,2021,and 2022,respectively.The prevalence of carbapenem-resistant P.aeruginosa(CRPae)and carbapenem-resistant Acinetobacter baumannii(CRAba)was 10.7％and 68.4％in 2020,17.5％and 75.2％in 2021,14.3％and 77.3％in 2022,respectively.About 84.6％of the 1 269 strains of Haemophilus influenzae were isolated from children and 15.4％isolated from adults.The prevalence of beta-lactamase-producing strains was 39.4％in the isolates from children and 46.8％in the isolates from adults.The β-lactamase-producing H.influenzae was resistant to ampicillin.Furthermore,some β-lactamase-nonproducing ampicillin-resistant(BLNAR)H.influenzae strains(27.0％)were also identified.Conclusions Antimicrobial resistance is still serious in this hospital,especially high prevalence of carbapenem-resistant organisms(CRO).Hospital infection prevention and control measures,antibiotic stewardship,and proactive CRO screening should be strengthened.More clinical specimens should be collected for suspected infections.Antimicrobial treatment should be prescribed empirically in time and adjusted when the results of antimicrobial susceptibility testing are available.

Objectives:To investigate the effect of circular RNA (circRNA) hsa_circ_0019217 on the biological function of chorionic trophoblast cell line (HTR8/SVneo) and its mechanism in the occurrence of pre-eclampsia (PE).Methods:The circRNA expression database was used to analyze the differentially expressed circRNA in placental tissues of PE women. The expression levels of hsa_circ_0019217 and miR-526b-5p were detected by reverse transcription real-time fluorescent quantitative PCR (RT-qPCR), and the subcellular localization of hsa_circ_0019217 was detected by fluorescence in situ hybridization. The proliferation, migration and invasion of trophoblast cells were detected by cell counting kit-8 (CCK-8) assay and transwell assay. Western blot and enzyme-linked immunosorbent assay (ELISA) were used to verify the effects of hsa_circ_0019217, miR-526b-5p and decorin (DCN) on matrix metalloproteinase 2 (MMP2), tissue inhibitor of metalloproteinase 2 (TIMP2), placental growth factor (PlGF) and human chorionic gonadotropin (hCG) protein expression levels. Dual luciferase reporter gene assay and RNA immunoprecipitation (RIP) assay were used to verify the interaction between hsa_circ_0019217, miR-526-5p and DCN.Results:(1) The analysis of circRNA expression database showed that the expression level of hsa_circ_0019217 was significantly increased in the placental tissues of PE women (fold change=67, P<0.05), and it was mainly located in the cytoplasm. (2) Knockdown of hsa_circ_0019217 promoted the proliferation, migration and invasion of HTR8/SVneo cells, increased the expression levels of MMP2 and PlGF, and decreased the expression levels of TIMP2 and hCG in HTR8/SVneo cells. (3) Hsa_circ_0019217 targeted adsorption of miR-526b-5p, and inhibition of miR-526b-5p reduced the proliferation, migration and invasion of HTR8/SVneo cells. The expression levels of MMP2 and PlGF in HTR8/SVneo cells were increased, and the expression levels of TIMP2 and hCG were decreased. Hsa_circ_0019217 knockdown and inhibiting miR-526b-5p could reverse the effect of hsa_circ_0019217 knockdown on promoting the proliferation, migration and invasion of HTR8/SVneo cells, and reversed the effect of hsa_circ_0019217 knockdown on the protein expression levels of MMP2, PlGF, TIMP2 and hCG. (4) miR-526b-5p targeted DCN in HTR8/SVneo cells, hsa_circ_0019217 knockdown reduced the expression level of DCN, and inhibiting miR-526b-5p increased the expression level of DCN. When hsa_circ_0019217 and miR-526b-5p were inhibited simultaneously, there was no significant change in the protein expression level of DCN. (5) Overexpression of miR-526b-5p promoted the proliferation, migration and invasion of HTR8/SVneo cells, while overexpression of DCN inhibited the proliferation, migration and invasion of HTR8/SVneo cells. Simultaneous overexpression of miR-526b-5p and DCN reversed the effects of miR-526b-5p overexpression on cell proliferation, migration and invasion. Overexpression of miR-526b-5p increased the expression levels of MMP2 and PlGF and decreased the expression levels of TIMP2 and hCG in HTR8/SVneo cells. Overexpression of DCN reduced the expression levels of MMP2 and PlGF and increased the expression levels of TIMP2 and hCG. Overexpression of miR-526b-5p and DCN reversed the effects of miR-526b-5p on the expression of these proteins. Conclusion:Hsa_circ_0019217 regulates the expression of DCN by adsorption of miR-526b-5p, thereby affecting the proliferation, migration and invasion of trophoblast cells and regulating the protein expression levels of MMP2, TIMP2, PlGF and hCG, which might be used as a target for early prevention of PE.

Emotional blunting leads to significant declines in cognitive function and activities of daily living in patients with Parkinson's disease, thereby impacting their quality of life and increasing the caregiver burden. Emotional blunting is a progressive condition, and early detection and intervention can slow its progression, making it necessary to assess emotional blunting in patients early. Currently, there are various tools for assessing emotional blunting, but there is a lack of evidence to guide tool selection. This review discusses the impact of emotional blunting on patients with Parkinson's disease and reviews existing assessment tools for emotional blunting, including their content, applications, advantages, and limitations. It also summarizes issues in the application of these tools and offers future directions, aiming to provide a basis for the identification and assessment of emotional blunting in Parkinson's disease patients.

Objective:To develop and validate a Self-care Ability Scale for Arteriovenous Fistula (AVF) in Maintenance Hemodialysis (MHD) patients.Methods:Guided by Orem's self-care theory, the initial item pool of the scale was developed through a literature review, semi-structured interviews, and group discussions. The initial scale was finalized after two rounds of expert consultation using the Delphi method. A convenience sampling method was used to recruit 418 MHD patients using AVF in January 2024 for item analysis, exploratory factor analysis and reliability testing. Another 293 MHD patients using AVF were recruited in March 2024 for confirmatory factor analysis.Results:The self-care ability scale for AVF in MHD patients included four dimensions: knowledge and skills of AVF self-care, willingness and attitude toward AVF self-care, recognition and prevention of AVF complications, and patient self-adjustment and adaptation, comprising 38 items. The content validity index at the scale level was 0.98. Exploratory factor analysis extracted four common factors with a cumulative variance contribution rate of 84.706%. Confirmatory factor analysis indicated good model fit, strong convergent validity, and ideal discriminant validity. The total Cronbach's α coefficient of the scale was 0.987; the split-half reliability coefficient was 0.902, and the test-retest reliability coefficient was 0.979.Conclusions:The Self-care Ability Scale for AVF in MHD patients demonstrates excellent reliability and validity, making it a suitable tool for assessing patients' ability to self-care for their AVF.

Objective:To construct a home rehabilitation program for patients with rib fractures based on empowerment theory and to evaluate its application effects.Methods:Literature related to rehabilitation of rib fracture patients published between June 2013 and May 2023 was systematically retrieved. After literature screening, clinical investigation, and expert consultation, the final version of the home rehabilitation program based on empowerment theory was developed. A total of 102 rib fracture patients discharged from the Department of Thoracic and Cardiovascular Surgery, Beijing Friendship Hospital, Capital Medical University, between October 2023 and June 2024 were selected as research subjects. According to discharge sequence, 52 patients were assigned to the observation group and 50 patients to the control group. The control group received routine health education and discharge follow-up, while the observation group received the empowerment theory-based home rehabilitation program. Pain levels, pulmonary function [forced vital capacity (FVC) , forced expiratory volume in 1 second (FEV1) ] , and exercise compliance were assessed at discharge and at 2, 4, 8, and 12 weeks post-discharge. Complication incidence and readmission rates were recorded and compared at 12 weeks after discharge.Results:At 4, 8, and 12 weeks post-discharge, pain scores in the observation group were lower than those in the control group, whereas FVC and FEV1 were higher; the differences were all statistically significant ( P<0.05) . At 12 weeks post-discharge, the incidence of complications and unplanned readmission rates in the observation group were lower than those in the control group, the exercise compliance score was higher, and the differences were all statistically significant ( P<0.05) . Conclusions:The home rehabilitation program for rib fracture patients constructed based on empowerment theory can reduce pain during home rehabilitation, promote recovery of pulmonary function, improve exercise compliance, and decrease the incidence of complications and unplanned readmissions.

PURPOSE: To investigate the regulatory role of nerve injury-induced protein 1 (NINJ1) in the anti-inflammatory function of human umbilical cord mesenchymal stem cells (hUC-MSCs) co-stimulated by interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α). METHODS: hUC-MSCs were expanded in vitro using standard protocols, with stem cell characteristics confirmed by flow cytometry and multilineage differentiation assays. The immunomodulatory properties and cellular activity of cytokine-co-pretreated hUC-MSCs were systematically evaluated via quantitative reverse transcription RT-qPCR, lymphocyte proliferation suppression assays, and Cell Counting Kit-8 viability tests. Transcriptome sequencing, Western blotting and small interfering RNA interference were integrated to analyze the regulatory mechanisms of NINJ1 expression. Functional roles of NINJ1 in pretreated hUC-MSCs were elucidated through gene silencing combined with lactate dehydrogenase release assays, Annexin V/Propidium Iodide apoptosis analysis, macrophage co-culture models, and cytokine Enzyme-Linked Immunosorbent Assay. Therapeutic efficacy was validated in a cecal ligation and puncture-induced septic mouse model: 80 mice were randomly allocated into 4 experimental groups (n=20/group): sham group (laparotomy without cecal ligation); phosphate-buffered saline-treated group (cecal ligation and puncture (CLP) + 0.1 mL phosphate-buffered saline); hUC-MSCs (small interfering RNA (siRNA)-interferon-gamma and tumor necrosis factor-alpha co-stimulation (IT))-treated group (CLP + hUC-MSCs transfected with scrambled siRNA); and hUC-MSCs (siNINJ1-IT)-treated group (CLP + hUC-MSCs with NINJ1-targeting siRNA). RESULTS: hUC-MSCs demonstrated compliance with International Society for Cellular Therapy criteria, confirming their stem cell identity. IFN-γ/TNF-α co-pretreatment enhanced the immunosuppressive capacity of hUC-MSCs, accompanied by the reduction of cellular viability, while concurrently upregulating pro-inflammatory cytokines such as interleukin-6 and interleukin-1β. This co-stimulation significantly elevated NINJ1 expression in hUC-MSCs, whereas genetic silencing of NINJ1 effectively suppressed pro-inflammatory cytokine production and attenuated damage-associated molecular patterns release through inhibition of programmed plasma membrane rupture. Furthermore, the NINJ1 interference potentiated the ability of cytokine-pretreated hUC-MSCs to suppress LPS-induced pro-inflammatory responses in RAW264.7 macrophages. In cecal ligation and puncture-induced sepsis model, NINJ1-silenced hUC-MSCs exhibited enhanced therapeutic efficacy, manifested by reduced systemic inflammation and multi-organ damage. CONCLUSION Our findings shed new light on the immunomodulatory functions of cytokine-primed MSCs, offering groundbreaking insights for developing MSC-based therapies against inflammatory diseases via interfering the expression of NINJ1.
