Objective To explore the relationship between the intraoperative plasma transfusion volume,the changes of blood coagulation test values and the clinical prognosis of surgical patients,so as to provide a theoretical basis for guiding the rational use of blood during the operation.Methods The clinical data of 556 surgical patients who received plasma in-fusion from January 2017 to December 2020 in Sun Yat-sen Memorial Hospital were collected.Patients were divided into low plasma dose group(＜15 mL/kg)and high plasma dose group(≥15 mL/kg).The univariate regression analysis,logistic multivariate regression analysis and linear regression analysis were used to explore the relationship of plasma dose,the chan-ges of coagulation indicators and the clinical prognosis.Results A total of 556 surgical patients were included in the study and the median(interquartile range)of plasma transfusion volume for all patients during the operation was 10.5(8.5～14.0)mL/kg.In multivariate regression analysis,an increase of 1 mL/kg of intraoperative plasma dose resulted in an in-creased risk of red blood cell infusion within 24 hours after surgery[OR(95%CI)1.16(1.01,1.33),P＜0.05],an in-crease in the ICU stays[Mean(95%CI)0.19(0.03,0.35),P＜0.05]and an increase in the hospitalization days[Mean(95%CI)0.55(0.27,0.81),P＜0.05].The preoperative INR value increased the risk of red blood cell infusion within 24 hours after surgery[OR(95%CI)1.82(1.33,2.50),P＜0.05],and increased the hospital mortality of postoperative pa-tients[OR(95%CI)2.15(1.09,4.24),P＜0.05];the decrease in INR reduced the risk of red blood cell infusion in pa-tients 24 hours after surgery[OR(95%CI)0.47(0.27,0.84),P＜0.05]and reduced hospital mortality[OR(95%CI)0.23(0.13,0.50),P＜0.05].Conclusion In surgical patients undergoing intraoperative plasma infusion,abnormal preopera-tive INR value and high intraoperative plasma infusion are related to poor clinical prognosis,while INR decrease(preopera-tive-postoperative)was related to better clinical results.

[Objective]To assess the impact of intraoperative plasma infusion dose and coagulation test value INR on the clinical prognosis of patients undergoing cardiac surgery,providing a basis for guiding rational blood use during cardi-ac surgery.[Methods]The clinical data of 305 surgical patients who received fresh frozen plasma transfusion during cardiac surgery were collected in Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2014 to December 2022.The patients were divided into low-dose group(plasma infusion dose<15 mL/kg,n=214)and high-dose group(plasma infusion dose≥15 mL/kg,n=91)based on the intraoperative plasma dose.Univariate analysis,correlation analysis and logistic multivariate regression analysis were used to analyze the relationship between plasma infusion dose,changes in INR before and after plasma transfusion,and the clinical prognosis of patients undergoing cardiac surgery.[Results]The median plasma infusion dose for all patients was 11.11(8.17-19.05)mL/kg,while the median plasma infusion dose in the high-dose group and the low-dose group was 17.78(15.69-20.91)mL/kg and 9.52(7.77-11.43)mL/kg,respectively,with a statistically significant difference(P<0.001).The median INR decrease in the high-dose and low-dose groups was 0.98(0.60-1.26)and 0.50(0.35-0.76),respectively,with a statistically significant difference(P<0.001).Logistic multi-variate regression analysis revealed that abnormally elevated preoperative INR values increased the risk of postoperative red blood cell transfusion within 24 hours in cardiac surgery patients(P<0.001),with an OR 95%CI of 6.757(3.068,14.822).Additionally,it also increased the risk of postoperative in-hospital mortality(P<0.001),with an OR 95%CI of 5.441(2.193,13.499).INR decrease reduced the risk of postoperative red blood cell transfusion within 24 hours in cardi-ac surgery patients(P=0.001),with an OR 95%CI of 0.244(0.107,0.558).Correlation analysis showed positive correla-tion between plasma infusion dose and postoperative ICU days(rs=0.569,P<0.001)and hospital days(rs=0.302,P<0.001)in cardiac surgery patients.[Conclusion]Among patients undergoing cardiac surgery who receive intraoperative plasma transfusion,high plasma infusion dose and abnormally elevated preoperative INR values are associated with poorer clinical outcomes,while patients who show a greater degree of INR correction after plasma transfusion exhibit better clini-cal results.

Objective:To compare demographic characteristics,clinical characteristics,therapeutic characteris-tics and physiological indicators of patients with bipolar Ⅰ disorder and bipolar Ⅱ disorder.Methods:A total of 381 patients with bipolar disorder(BD)diagnosed by the Diagnostic and Statistical Manual of Mental Disorders 5 th Edi-tion(DSM-5)were selected,including 302 patients with BD-Ⅰ(79.27％),74 patients with BD-Ⅱ(19.42％)and 5 patients with other specific and related disorders(1.31％).Demographic and clinical characteristics were collected with self-designed clinical information questionnaire.Multivariate logistic regression and multivariate linear regres-sion analysis were used for analysis.Results:Compared with patients with BD-Ⅱ,patients with BD-Ⅰ had more risk to have psychotic features(OR=5.75,95％CI:2.82-11.76),longer disease duration,and more repeated transcra-nial magnetic therapy(OR=3.09,95％CI:1.02-9.35),higher uric acid,total cholesterol and high-density lipo-protein.BD-Ⅰ in Han nationality was more common(OR=11.50,95％CI:1.76-75.30),and had lower education level(OR=10.22,95％CI:1.16-89.77),and less family history of psychosis(OR=2.34,95％CI:1.01-5.42).Conclusion:There are significant differences between BD-Ⅰ and BD-Ⅱ in demographic and clinical charac-teristics,treatment status,and physiological indicators,which could provide clues for exploring the pathogenesis of bipolar disorder.

Background With the aging of China's population, cognitive impairment in the elderly is receiving increasing public attention. Screening and intervention of people with mild cognitive impairment (MCI) are of great significance to prevent and reduce the occurrence of cognitive impairment. Objective To understand the prevalence and explore potential influencing factors of MCI in the elderly in Songjiang District, Shanghai, and to provide scientific basis for promoting early screening of cognitive impairment and precise intervention of MCI in the elderly in this area. Methods A cross-sectional study design was adopted. From August to October 2022, using multi-stage random sampling, 1800 elderly residents aged 60 years and above were screened for cognitive impairment in 6 neighborhood/village committees in 6 towns in Songjiang District. The survey questionnaires included a sociodemographic questionnaire, a health status and lifestyle questionnaire, the Instrumental Activities of Daily Living (IADL), the Patient Health Questionnaire (PHQ-9), and the Mini-Mental State Examination (MMSE). Prevalence rates of MCI among the elderly by selected social demographic characteristics, health status, and lifestyle were estimated, and potential influencing factors of MCI were evaluated by binary logistic regression. Results A total of 209 elderly residents with MCI and 1591 healthy elderly residents were detected, and the prevalence of MCI in the elderly aged 60 and above was 11.6% in Songjiang District. Being physically active (OR=0.556, 95%CI: 0.399, 0.774) reduced the risk of MCI. Illiteracy (OR=1.810, 95%CI: 1.239, 2.644), primary school education level (OR=3.454, 95%CI: 2.342, 5.092), non-participation in social activities (OR=1.945, 95%CI: 1.360, 2.781), IADL damaged (OR=3.173, 95%CI: 2.137, 4.712), and depression (OR=1.957, 95%CI: 1.112, 3.443) increased the risk of MCI (P＜0.05). Conclusion The prevalence of MCI among the elderly in Songjiang District is lower than the national average. Educational level, physical activity, participation in social activities, IADL, and depression may be the influencing factors of MCI in the elderly. It is recommended to carry out early screening, early detection, and early intervention for cognitive impairment in the elderly. Improving involvement in physical exercise and increasing participation in social activities are encouraged. Special attention should be paid to the needs of vulnerable groups such as low education level and disabled elderly during a community MCI intervention program.
