Objective To explore the prevalence and relationship of urinary incontinence and depression among elderly female patients.Methods A total of 118 female patients older than 60 years old were interviewed face to face.The prevalence of urinary incontinence and depression were estimated using the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form-Chinese (ICIQ-SF-Chinese) and Geriatric Depression Scale-15 (GDS-15).Linear regression and Spearman correlation were used to identify the relationship between urinary incontinence and depression.Results Urinary incontinence was found in 27.1％ (32/118),and depression was in 39.0％ (46/118) of the survey population.Urinary incontinence with depression was found in 13.6％ (16/118) of the overall population.Urinary incontinence was positively correlated with depression,r=0.211,P＜0.05.The frequency of entertainment and urinary incontinence were significantly related to depression symptoms,P＜0.05.Conclusions Urinary incontinence appears to possess an additive effect on incidence of depression,which seriously affects both physical and mental health of patients.Clinicians should give patients health education and intervention measures at early stage.

ObjectiveTo study the relation between white blood cell(WBC) count and left ventricular (LV) remodeling after emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).MethodsA total of 117 ST segment elevation AMI patients having underwent emergency PCI were enrolled.WBC count,cardiac troponin Ⅰ (cTnI),high-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide(NT-proBNP) were obtained at admission before PCI.According to the WBC count level,patients were divided into normal WBC group(WBC count ≤ 10 ×109/L,60 cases) and elevated WBC group(WBC count＞ 10 × 109/L,57 cases).Two-dimensional echocardiography was applied after PCI.The relation between WBC count and LV remodeling prognosis including LV ejection fraction(LVEF),LV end diastolic diameter(LVEDD) and LV aneurysm were compared after AMI.ResultsAdmission NT-proBNP,hs-CRP and cTnI peak in elevated WBC group were higher than those in normal WBC group [ (2408.83 ± 3173.39) pg/L vs.(713.11 ± 636.82) pg/L,(39.64 ± 59.51) mg/L vs.(11.23 ± 14.14) mg/L,(107.76 ± 107.71) pg/L vs.(62.23 ± 87.79) pg/L,P ＜0.05].Admission WBC count was positively correlated with LVEDD and negatively correlated with LVEF(P ＜0.01 ).Patients with LV aneurysm had higher WBC count than those without LV aneurysm[ ( 12.59 ± 5.22) × 109/L vs. (9.27 ± 2.60) × 109/L,P =0.001 ].Multivariate analyses showed that admission WBC count ≥ 10.5 × 109/L was an independent determinant of LV aneurysm(OR =22.5,95％ CI:2.69-187.83,P ＜ 0.01 ),and this cut-off value yielded sensitivity of 76.9％ and specificity of 69.7％ respectively.Conclusion Admission WBC count may be considered as a prognostic biological tag in the prediction of the development of LV remodeling after emergency PCI in patients with AMI.

Objective To understand the incidence of common geriatric syndromes in hospitalized patients,and analyze the relationship between different kinds of geriatric syndromes.Methods A crosssectional study was conducted by five well-trained investigators-300 patients were chosen from geriatric department and medical department within 3 top three hospitals in Chengdu.Results 300 copies of questionnaires were distributed in total,and 300 questionnaires were returned (response rate 100％).Among those,277 questionnaires were considered valid (valid response rate 92.3％).Among those elderly which were above 65 years old,having risk of falling accounted for 91.3％,feeling pain accounted for 79.1％,chronic constipation accounted for 59.2％,having risk of malnutrition accounted for 49.1％,malnutrition accounted for 28.2％,having risk of pressure ulcers accounted for 32.5％,incontinence accounted for 25.3％,and dysphagia accounted for 17％.The correlation among these syndromes was signifcant.Conclusions The overall incidence of geriatric syndromes in hospitalized patients is higher than that in the community.These syndromes are correlated with each other.One can be a risk factor of other geriatric syndromes and also could affect each other.

Objective:To explore the mechanism of interleukin-1?(IL-1?) induced AHR.Methods:The authors work out an original model of AHR induced by IL-1? administered intratracheally to guinea pigs,and investigate the effects of neurokinin released from intrinsic airway neurons on the development of this airway hyperresponsiveness,PC 20 values were significantly lower in animals given IL-1? than that in controls( P 0 05),showing complete inhibition of IL-1? induced AHR by capsaicin pretreatment.PC 20 values were significantly higher in animals with NK 1 receptor antagonist pretreatment than that in animals exposed to IL-1?( P

Objective:To construct a new nurse pre-job training program based on transformative learning and explore its preliminary application effect.Methods:A quasi-experimental study was conducted, and 52 new nurses enrolled in 2019 in a three-A hospital of Hangzhou were randomly divided into experimental group ( n=26) and control group ( n=26). The experimental group adopted transformative learning based pre-job training program for new nurses, while the control group adopted traditional pre-job training program for new nurses. SPSS 20.0 and Microsoft Excel 2010 were performed for data processing, and t test and Fisher's exact probability test were used for statistical analysis. Results:After the training, the comparison of two groups of new nurses showed that, the total score of clinical core competence of the experimental group (226.62±32.84) was higher than that of the control group (197.00±29.54), the total score of self-efficacy of the experimental group (28.46±4.94) was higher than that of the control group (24.31±4.76), the total score of the transition shock of the experimental group (77.23±14.13) was lower than that of the control group (91.27±17.98), and the mean value of clinical assessment of the experimental group (73.16±17.05) was higher than that of the control group (61.58±14.24), all with statistical significance ( P<0.05). Conclusion:The pre-job training program for new nurses based on transformative learning can improve the clinical ability and self-efficacy of new nurses, reduce the transition shock of new nurses, and have a profound impact on their career.

Mammals exhibit limited heart regeneration ability, which can lead to heart failure after myocardial infarction. In contrast, zebrafish exhibit remarkable cardiac regeneration capacity. Several cell types and signaling pathways have been reported to participate in this process. However, a comprehensive analysis of how different cells and signals interact and coordinate to regulate cardiac regeneration is unavailable. We collected major cardiac cell types from zebrafish and performed high-precision single-cell transcriptome analyses during both development and post-injury regeneration. We revealed the cellular heterogeneity as well as the molecular progress of cardiomyocytes during these processes, and identified a subtype of atrial cardiomyocyte exhibiting a stem-like state which may transdifferentiate into ventricular cardiomyocytes during regeneration. Furthermore, we identified a regeneration-induced cell (RIC) population in the epicardium-derived cells (EPDC), and demonstrated Angiopoietin 4 (Angpt4) as a specific regulator of heart regeneration. angpt4 expression is specifically and transiently activated in RIC, which initiates a signaling cascade from EPDC to endocardium through the Tie2-MAPK pathway, and further induces activation of cathepsin K in cardiomyocytes through RA signaling. Loss of angpt4 leads to defects in scar tissue resolution and cardiomyocyte proliferation, while overexpression of angpt4 accelerates regeneration. Furthermore, we found that ANGPT4 could enhance proliferation of neonatal rat cardiomyocytes, and promote cardiac repair in mice after myocardial infarction, indicating that the function of Angpt4 is conserved in mammals. Our study provides a mechanistic understanding of heart regeneration at single-cell precision, identifies Angpt4 as a key regulator of cardiomyocyte proliferation and regeneration, and offers a novel therapeutic target for improved recovery after human heart injuries.
