Objective To explore the effect of sequential organ failure assessment (SOFA) combined with soluble programmed death factor-1 (sPD-1) level on the prognosis of patients with sepsis. Methods A total of 86 patients with sepsis in our hospital from March 2019 to March 2021 were selected and divided into survival group (59 cases) and death group (27 cases) according to their prognosis (28-day outcome). The levels of sPD-1, inflammatory cytokines, SOFA and APACHEⅡ scores of two groups were recorded. The risk factors of 28-day mortality were analyzed. The prognostic values of SOFA+sPD-1 in patients with sepsis were analyzed by ROC curve. Results Age, C-reactive protein (CRP), procalcitonin (PCT) and sPD-1 levels and SOFA, APACHEⅡ scores of death group were higher than those of survival group (P＜0.05). By Logistic regression analysis, sPD-1 level, SOFA and APACHEⅡ scores were identified as independent predictors of 28-day death in patients with sepsis (P＜0.05). After combining prediction, the area under the ROC curve of SOFA+sPD-1 was the largest (0.862), and the sensitivity and specificity were 88.89% and 88.14% respectively. Conclusion In the prognosis evaluation of patients with sepsis, both sPD-1 level and SOFA score were independent predictors of 28-day mortality, and SOFA+sPD-1 was more effective in predicting the prognosis of patients with sepsis.

Objective To analyze the distribution characteristics of death causes and influence of major death causes on life expectancy of Shiqi district in 2019, and provide support to develop strategies for disease prevention and control. Methods The 2019 death causes of residents in Shiqi district were classified by International Classification of Diseases-10 (ICD-10). The life expectancy, mortality rate, cause eliminated life expectancy, standardized mortality rate, potential years of life lost rate (PYLLR), and potential years of life lost (PYLL) were calculated. Results The mortality of residents of Shiqi district in 2019 was 636.88/10⁵. The male mortality and female mortality were 706.39/10⁵and 569.86/10⁵, respectively. The top five causes of death in Shiqi district were malignant tumors, heart diseases, cerebrovascular diseases, respiratory diseases, and endocrine nutrition and metabolic diseases. The malignant tumors with top three death rates were lung cancer, liver cancer, and colorectal and anal cancer. The highest death rate of heart disease was ischemic heart disease. The top three causes shortening life expectancy were malignant tumors(4.40 years), heart diseases(2.76 years), and cerebrovascular diseases (1.79 years). The PYLL was 10 001.32 person-year, the PYLLR was 58.64‰ in Shiqi distric,2019. The top three causes of life loss were malignant tumors, injury and cerebrovascular diseases. The PYLLR of those three death causes were 27.80‰, 7.72‰, and 5.18‰, respectively. Conclusion Malignant tumors, heart disease and cerebrovascular diseases were the main death causes and the major diseases for life lost of residents in Shiqi district, which caused heavy disease burden and should be focused in the future. For protecting the residents from the harm due to chronic non-communicable diseases, comprehensive preventive and controling measures should be taken by government.

Objective To explore the risk factors for acute exacerbation (AE) in patients with idiopathic pulmonary fibrosis (IPF) and connective tissue disease associated with fibrotic interstitial lung disease (CTD-fILD). Methods We retrospectively reviewed 25 patients with AE-CTD-fILD and 26 patients with AE-IPF, and Kaplan-Merier was used to analyze the survival of the two groups of patients. The impact of age,gender, smoking,WBC,CRP,ESR and tumor markers on acute exacerbation death were performed by Cox regression analysis. Results The AE-IPF patients had a higher proportion of men,age and smoking,and a lower ESR compared with AE-CTD-fILD patients(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 ). 11 cases of 26 patients with AE-IPF and 5 cases of 25 patients with AE-CTD-fILD died within 90 days, Log-rank tests showed patients with CTD-fILD had similar mortality rate compared with IPF patients after AE(42.3% vs 20%,P=0.073). The WBC count was negatively correlated with survival and the independent predictors for patients with AE-IPF and AE-CTD-fILD after adjusting for other clinical variates in Cox regression models(HR=1.305,P=0.001;HR=1.529,P=0.009). CA15-3 may be a risk factor for death of AE-IPF patients(HR=1.015,P=0.005). Conclusion AE-CTD-fILD and AE-IPF were associated with similar poor short-term survival, WBC count and plasma CA15-3 may be the independent survival predictors respectively for patients with acute exacerbation of pulmonary fibrosis in short term.
