Objective:In order to apply the index system for clinical evaluation of implementation effect in hospitals.Methods:A total of 862 patients with vaginal delivery from 9 hospitals were randomly divided into an clinical pathway group (n=496) and a control group (n=366).The patients in the control group received traditional treatment procedure while the patients in the clinical pathway group experienced procedure of the clinical treatment.The index system was used for clinical evaluation of implementation effect.Results:There were obvious advantages in 15 indicators in the clinical pathway group than those in the control group (P＜0.05).The comprehensive score of the clinical pathway group was higher than the control group of the corresponding grade and nature of the hospital.The comprehensive score for secondary hospitals (Ci=0.7967) were higher than that for the tertiary hospitals (Ci=0.2033).The comprehensive score for the general hospitals (Ci=0.8948) were higher than that for the specialized hospitals (Ci=0.1052).As for clinical implementation effect,the secondary hospitals were better than the tertiary hospital,and the general hospitals were better than the specialized hospitals.Conclusion:The index system for clinical evaluation could quantify the implementation effect,and compare the implementation effect in different hospitals,which provides reference for the management of clinical pathway.

BACKGROUND:A pathophysiological feature of septic organ failure is endothelial dysfunction in sepsis(EDS).The physiological and pathological mechanism of sepsis is considered to be vascular leakage caused by endothelial dysfunction.These pathological changes lead to systemic organ injury.However,an analysis using bibliometric methods has not yet been conducted in the field of EDS.This study was conducted to provide an overview of knowledge structure and research trends in the field of EDS. METHODS:Based on previous research,a literature search was performed in the Web of Science Core Collection(WoSCC)for publications associated with EDS published between the year 2003 and 2023.Various types of data from the publications,such as citation frequency,authorship,keywords and highly cited articles,were extracted.The"Create Citation Report"feature in the WoSCC was employed to calculate the Hirsch index(h-index)and average citations per item(ACI)of authors,institutions,and countries.To conduct bibliometric and visualization analyses,three bibliometric tools were used,including R-bibliometrix,CiteSpace(co-citation analysis of references),and VOSviewer(co-authorship analysis of institutions,co-authorship analysis of authors,co-occurrence analysis of keywords). RESULTS:After excluding invalid records,the study finaly included 4,536 publications with 135,386 citations.Most of these publications originated in the USA,China,Germany,Canada,and Japan.Harvard University emerged as the most prolific institution,while professor Jong-Sup Bae and his research team at Kyungpook National University emerged as authors with the greatest influence.The"protein C","tissue factor","thrombin","glycocalyx","acute kidney injury","syndecan-1"and"biomarker"were identified as prominent areas of research.Future research may focus on molecular mechanisms(such as as vascular endothelial[VE]-cadherin regulation)and therapeutic interventions to enhance endothelial repair and function. CONCLUSION:Our findings show a growing interest in EDS research.Key areas for future research include signaling pathways,molecular mechanisms,endothelial repair,and interactions between endothelial cells and other cell types in sepsis.

OBJECTIVE: To investigate the effect of social support and coping style on the stress and mental health in relatives of patients with traumatic brain injury. METHODS: The stress, mental health, social support and coping style were investigated in 300 relatives of patients with traumatic brain injury by Relative Stress Scale, Symptom Checklist-90, Social Support Rating Scale and Simplified Coping Style Questionnaire in Changsha City. RESULTS: The mental health problems in relatives of patients with traumatic brain injury were closely related to the levels of stress, the ways of coping and the social support. In addition to the direct eff ect of stress on mental health in relatives of patients, the ways of coping and social support functioned as a mediator in this regard. The value of mesomeric eff ect for coping styles and social support ranged from 23.6% to 43.0%, and social support had an advantage over the coping styles. CONCLUSION Social support and coping styles should be considered in psychological nursing program to prevent and adjust the mental distress in relatives of patients with traumatic brain injury, which is beneficial to the treatment and recovery for patients.

OBJECTIVE: To analyze the relationship between the ischemic ST-T changes in electrocardiogram (ECG) and the coronary artery diseases based on the perspective of diagnostics.
 METHODS: A total of 341 patients, who underwent coronary angiography in Department of Cardiology of Xiangya Hospital, Central South University from June 2013 to April 2014, were enrolled for this study. The internationally recognized diagnostic criteria for ischemic ST-T changes in ECG and the Judkins diagnostic criteria for coronary angiography were applied, respectively. The sensitivity and specificity of ECG were analyzed.
 RESULTS: There were more ischemic ST-T changes in women than that in men (P<0.01). Ischemic changes in coronary angiography were not significantly different between male and female patients (P>0.05). For ischemic diagnostic tests by ECG ST-T, the total sensitivity and specificity was 83.6% and 54.4%, respectively. The sensitivity and specificity was 82.3% and 68.0% or 85.0% and 28.2% in the male or female group, respectively. 
 CONCLUSION Ischemic ST-T changes in ECG possess important value in the diagnosis of the coronary artery diseases. The sensitivity of ECG in the diagnosis of myocardial ischemia in women was higher than that in men, whereas the specificity of ECG in the diagnosis of myocardial ischemia in men was higher than that in women.
