Objective:To analyze the changes in the variables of venous thromboembolism (VTE) management among inpatients after implementing clinical care classification (CCC) system, and to explore the impacts.Methods:This was a quasi experimental study. Based on the network monitoring data in Zhongshan Hospital, Fudan University, all the inpatients were included in this study from January 2022 to June 2023. According to the date of implementing CCC, we took July 2022 as the intervention cut-off point, and two phases of pre-CCC (January 2022 to June 2022) and post-CCC (July 2022 to June 2023) were defined. The interrupted time series (ITS) analysis was used to evaluate the impacts of implementing CCC system on VTE management among inpatients.Results:ITS analysis showed that in the period of post-CCC (August 2022 to June 2023), the slope of VTE evaluation rate was 0.000 415 5, with a significant upward trend ( t=2.49, P<0.05). In the month of CCC system launched (July 2022), the implementation rate of VTE preventive measures increased significantly, with a significant statistical difference ( t=3.10, P<0.05). In the post-CCC phase (August 2022 to June 2023), the slope of VTE preventive measures implementation rate was -0.012 876, with no significant statistical difference ( P>0.05). The implementation of CCC system had no significant impacts on the overall and high-risk incidence of VTE among inpatients. Conclusions:After the implementation of the CCC system, the VTE evaluation rate of inpatients increased significantly, which suggesting that the CCC system standardized the clinical VTE management among inpatients.

Objective:To explore the predictive value of the prognostic nutritional index (PNI) in concurrently infected patients with acute-on-chronic liver failure (ACLF).Methods:220 cases with ACLF diagnosed and treated at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2016 were selected. Patients were divided into an infection and non-infection group according to whether they had co-infections during the course of the disease. Clinical data differences were compared between the two groups of patients. Binary logistic regression analysis was used to screen out influencing factors related to co-infection. The receiver operating characteristic curve was used to evaluate the predictive value of PNI for ACLF co-infection. The measurement data between groups were compared using the independent sample t-test and the Mann-Whitney U rank sum test. The enumeration data were analyzed using the Fisher exact probability test or the Pearson χ2 test. The Pearson method was performed for correlation analysis. The independent risk factors for liver failure associated with co-infection were analyzed by multivariate logistic analysis. Results:There were statistically significant differences in ascites, hepatorenal syndrome, PNI score, and albumin between the infection and the non-infection group ( P ?

Objective To analyze the consistency between computer tomography angiography(CTA)and digital subtraction angiography(DSA)in evaluating the global limb anatomic staging system(GLASS)stage of patients with chronic limb-threatening ischemia(CLTI).Methods The clinical data of patients with CLTI,who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University of China to receive treatment between January 2017 and December 2020,were retrospectively analyzed.Taking the DSA assessment as the gold standard,the consistency of CTA and DSA in evaluating the GLASS stage of patients with CLTI was analyzed.Results In the assessment of GLASS stage of CLTI,CTA showed strong agreement with DSA.The weighted Kappa coefficient of CTA and DSA for the staging of femoropopliteal segment was 0.798(95％CI=0.722-0.873,P＜0.01),and the weighted Kappa coefficient of CTA and DSA for the staging of infrapopliteal artery segment was 0.785(95％ CI=0.725-0.845,P＜0.0l).For the overall staging of GLASS,the weighted Kappa coefficient of CTA and DSA was 0.832(95％ CI=0.752-0.91 1,P＜0.01).All the above results indicated that a very strong consistency existed between CTA and DSA in evaluating the GLASS stage of patients with CLTI.Conclusion CTA examination of lower limb can accurately evaluate GLASS score and stage of CLTI patient's target lesions,which is helpful in diagnosing lower extremity arteriosclerosis occlusion disease as well as in assessing the technical difficulty degree of its revascularization operation.(J Intervent Radiol,2024,33:300-303)

Objective To evaluate the diagnostic value of cardiac magnetic resonance(CMR)in patients with severe connective tissue disease-associated pulmonary hypertension(CTD-PAH).Methods A total of 48 patients diagnosed with CTD-PAH by right heart catheterization(RHC)in Tianjin Medical University General Hospital from June 2018 to July 2021 were retrospectively included.The parameters of right ventricular(RV)morphology,function and ventricular septum(IVS)were obtained by manual delineation on CMR images and corrected by body surface area.The late gadolinium enhancement(LGE)myocardial mass(MM)and its percentage in left ventricular(LV)MM were manually sketched and calculated on LGE images.The patients were divided into the mild-moderate group and the severe group according to mean pulmonary arterial pressure(mPAP).CMR parameters were compared between the two groups.The diagnostic value of CMR for severe CTD-PAH was analyzed by receiver operating characteristic(ROC)curve.Results A total of 48 patients with CTD-PAH were included in this study.The curvature of interventricular septum(CIVS)and RV ejection fraction(EF)were lower in the severe group than those in the mild-moderate group,and the time proportion of IVS deformation,RV end-diastolic volume index(EDVI),RV end-systolic volume index(ESVI)and RV MM were higher than those in the mild-moderate group(P＜0.05).ROC curve analysis showed that RV MM,time proportion of IVS deformation and RV ESVI had better diagnostic efficacy in severe CTD-PAH patients(AUC was 0.792,0.766 and 0.731,respectively).The combined AUC of the three parameters was 0.840,specificity was 85.7%and sensitivity was 79.4%.Conclusion The parameters of RV and IVS measured by CMR can effectively evaluate patients with severe CTD-PAH and directly reflect serverity of cardiac impairment in patients with severe CTD-PAH from the morphological and functional perspective.

Objective To establish a scoring system based on the preoperative serum levels of alpha-fetoprotein (AFP) and alkaline phosphatase (ALP), and to investigate its value in predicting the prognosis of patients with resectable hepatocellular carcinoma (HCC). Methods A retrospective analysis was performed for 154 HCC patients who underwent hepatectomy as the initial treatment in Tianjin First Central Hospital from January 2016 to August 2019. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off values of serum AFP and ALP; the Kaplan-Meier curve and the log-rank test were used for survival analysis to evaluate the relationship between the AFP-ALP score and disease-free survival (DFS); univariate and multivariate Cox regression analyses were used to identify the independent prognostic factors for HCC patients. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. Results The ROC curve analysis showed that serum AFP had an optimal cut-off value of 250.0 ng/mL and an area under the ROC curve (AUC) of 0.674 (95% confidence interval [ CI ]: 0.580-0.767) in predicting DFS, while serum ALP had an optimal cut-off value of 95.5 U/L and an AUC of 0.745 (95% CI : 0.652-0.838). The survival analysis showed that high preoperative serum levels of AFP (≥250.0 ng/mL) and ALP (≥95.5 U/L) were significantly associated with the poor prognosis of HCC patients ( P < 0.001). Based on the AFP-ALP score, all HCC patients were further divided into 0-point group (AFP < 250.0 ng/mL and ALP < 95.5 U/L), 1-point group (AFP≥250.0 ng/mL, ALP < 95.5 U/L; or AFP < 250.0 ng/mL, ALP ≥95.5 U/L), and 2-point group (AFP≥250.0 ng/mL and ALP≥95.5 U/L). The survival curves showed that the 0-, 1-, and 2-point groups had a median DFS of 60.0 (56.7-67.3) months, 20.0 (1.4-36.6) months, and 13.0(7.9-18.0) months, respectively, and there were significant survival differences between the three groups ( P < 0.05). Serum AFP-ALP score (1 point vs 0 point: hazard ratio [ HR ]=4.060, 95% confidence interval [ CI ]: 2.050-8.039, P < 0.001; 2 points vs 0 point: HR =4.583, 95% CI : 2.385-8.805, P < 0.001) was an independent prognostic factor for HCC patients. Conclusion The scoring system based on the serum levels of AFP and ALP can effectively identify HCC patients with poor prognosis, and therefore, it might be used as a simple and reliable tool for prognostic assessment in the clinical treatment of HCC.

ObjectiveTo investigate the influencing factors for the prognosis of patients with acute－on－chronic liver failure （ACLF）， and to establish a short－term prognostic model. MethodsA retrospective analysis was performed for the baseline clinical data of 247 patients with ACLF who were hospitalized in Department of Infectious Diseases， The First Affiliated Hospital of Xi’an Jiaotong University， from January 2011 to December 2016， and the patients were divided into survival group and death group. The two groups were compared to identify the influencing factors for prognosis； a prognostic model was established， and the receiver operating characteristic （ROC） curve was used to assess its predictive efficacy and determine the optimal cut－off value. The independent－samples t test was used for comparison of normally distributed continuous data between groups， and the Mann－Whitney U rank sum test was used for comparison of non－normally distributed continuous data between groups； the Fisher’s exact test or the Pearson’s chi－square test was used for comparison of categorical data between groups. The univariate and multivariate logistic regression analyses were used to investigate the independent risk factors for 28－ and 90－day prognosis， and the Kaplan－Meier method was used to plot the 28－day survival curves. ResultsA total of 220 patients with ACLF were included based on the inclusion and exclusion criteria； there were 148 patients in the 28－day survival group and 72 patients in the 28－day death group， with a 28－day transplantation－free survival rate of 67.27%； there were 115 patients in the 90－day survival group and 105 patients in the 90－day death group， with a 90－day transplantation－free survival rate of 52.27%. The logistic regression analysis showed that female sex （odds ratio ［OR］=2.149， P=0.030）， high Model for End－Stage Liver Disease （MELD） score （OR=1.120， P<0.001）， and low lymphocyte count （OR=0.411， P=0.002） were independent risk factors for 28－day prognosis， and an LS－MELD model for 28－day prognosis was established as Logit （28－day prognosis）=－3.432+0.765×sex－0.890×lymphocyte count×10^－9+0.113×MELD（1 for male sex and 2 for female sex）. The ROC curve analysis showed that this model had an optimal cut－off value of 0.35， and then the patients were divided into low LS－MELD group （≤0.35） and high LS－MELD group （>0.35）； the low LS－MELD group had a significantly higher 28－day survival rate than the high LS－MELD group （P<0.001）. ConclusionPeripheral blood lymphocyte count combined with sex and MELD score has a certain value in predicting the short－term prognosis of ALCF patients.

Objective? To understand the attitude and behavioral status quo of obstetric nursing staff in caring for maternal women with fetal loss, so as to provide effective reference for the establishment of obstetric grief nursing model. Methods? By convenience sampling, nurses and midwives working in the obstetrics department in a ClassⅢ Grade A obstetrics and gynecology hospital of Beijing from March 1st to 31st of 2017 were selected. Self-designed "Questionnaire on Attitude and Behavior of Obstetric Nurses on Grief Nursing" was used to investigate the attitude and behaviour status of the obstetric nurses and midwives on grief nursing. The questionnaires were distributed collected by 2 charge nurses in obstetric department. The data were analyzed using SPSS 23.0 software. Results? A total of 165 questionnaires were distributed and 165 ones were retrieved. The score of grief nursing attitudes of obstetric ward nurses was (37.03±7.01), and the score of grief nursing behaviors was (27.08±5.61); the score of grief nursing attitudes of obstetric ward midwives was (39.15±7.22), and the score of grief nursing behaviors was (16.76±4.51).There were significant differences in the scores of grief nursing attitudes among nurses of different ages, working years and professional titles (P＜ 0.05); there were statistical difference in scores of grief nursing behaviors from nurses with different working years and professional titles(P＜0.05). The highest score of grief nursing attitudes was (4.25±0.85), and the lowest was (2.81±1.05); the highest score of grief behaviors was (4.33±0.98), and the lowest was (1.79±1.04). Conclusions? Obstetric nurses' perception of grief nursing is relatively limited and lack of standardized obstetric grief nursing mode. It is necessary to further improve the education and training of sensitive culture of medical staff in grief nursing consultation. A standardized grief nursing model should be established according to the psychological status and actual psychological needs of the mothers with lost fetuses in China.
