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 assess the value of serum tumor specific protein 70 (SP70) for prognostic stratification in acute myeloid leukemia (AML).Methods:A cohort study design was adopted. 129 newly diagnosed AML patients from September 2022 to January 2024 at the Hematology Department of the First Affiliated Hospital of Nanjing Medical University were included, as well as a control group consisted of 120 healthy individuals and 7 cases with benign hematologic diseases during the same period (total 127 cases). Clinical data were collected from Electronic Medical Records. According to the 2023 edition of the Chinese Leukemia Diagnosis and Treatment Guidelines, AML patients with good or moderate prognosis were categorized as low-to-intermediate risk, while those with poor prognosis were high-risk group. Univariate and multivariate logistic regression analyses were used to identify variables significantly associated with AML prognostic risk. ROC analysis was used to evaluate diagnostic performance. A nomogram for predicting patient prognostic risk was constructed by R 4.0.2 software, and the internal validation was performed using bootstrapping.Results:Among 129 AML patients, there were 71 males (55.0%) and 58 females (45.0%), with 42 (32.6%) classified as high-risk and 87 (67.4%) as low-intermediate risk. The high-risk group had a significantly higher median age [62 (48, 67) years] compared to the low-intermediate risk group [50 (35, 63) years, Z=-2.381, P=0.017], and a significantly higher proportion of males (30 patients, 71.4%) compared to the low-intermediate risk group (41 patients, 47.1%, χ 2=6.760, P=0.009). Multivariate logistic regression analysis indicated that serum SP70 ( OR=2.54, 95% CI: 1.68-3.84, P<0.001), hemoglobin (HB) ( OR=0.96, 95% CI: 0.93-0.99, P<0.05), and bone marrow blast (BM blast) ( OR=1.07, 95% CI: 1.02-1.13, P<0.05) were independent risk factors for high-risk prognosis in AML patients. ROC analysis showed that the area under the curve (AUC) for SP70 predicting high-risk patients was 0.908 (cut-off value of 5.74 ng/ml, 95% CI: 0.845-0.952, sensitivity 90.5%, specificity 82.8%). The combined model of serum SP70, HB, and BM blasts had an AUC of 0.931 (95% CI: 0.890-0.973); C-index=0.925 (95% CI: 0.876-0.963),with no statistically significant difference compared to serum SP70 alone ( Z=1.693, P>0.05). Conclusion:Serum SP70 may be a promising non-invasive molecular biomarker for prognostic stratification in AML.

Objective:To compare the eradication rate and incidence of adverse reactions between cefuroxime-containing and amoxicillin-containing bismuth quadruple regimen in the treatment of Helicobacter pylori ( H. pylori), and to evaluate the efficacy and safety of cefuroxime in the H. pylori infection patients with positive penicillin skin test results. Methods:From December 2020 to December 2021, a total of 498 patients who received initial H. pylori eradication treatment at the H. pylori Specialized Outpatient Clinic of the First Affiliated Hospital of Soochow University were selected to participate in this prospective cohort study. According to the history of penicillin allergy or positive penicillin skin test results, the patients were divided into amoxicillin group and cefuroxime group. A total of 394 patients were included in the amoxicillin group, and the treatment regimen was esomeprazole 20 mg, bismuth 220 mg, amoxicillin 1 g and clarithromycin 500 mg orally twice a day. A total of 104 patients were included in the cefuroxime group, and the treatment regimen was esomeprazole 20 mg, bismuth 220 mg, cefuroxime 500 mg and clarithromycin 500 mg orally twice a day. The treatment period was 14 days. 13C-urea breath test was conducted during 4 to 8 weeks after the treatment. The eradication rates of the 2 groups were compared by intention-to-treat (ITT) analysis and per-protocol (PP) analysis. The incidence of adverse reactions was compared between the 2 groups. Chi-square test was used for statistical analysis. Results:The results of ITT analysis and PP analysis indicated that the eradication rates of amoxicillin group were 84.3% (332/394, 95% confidence interval (95% CI) 80.6% to 87.6%) and 90.5% (332/367, 95% CI 87.2% to 93.3%), respectively, and the eradication rates of cefuroxime group were 62.5% (65/104, 95% CI 52.7% to 71.7%) and 69.1% (65/94, 95% CI 58.8% to 78.7%), respectively. The eradication rates of amoxicillin group in ITT and PP analysis were both higher than those of cefuroxime group, and the differences were statistically significant ( χ2=24.11 and 28.44, both P<0.001). The incidence of adverse reactions of amoxicillin group and cefuroxime group was 10.9% (43/394) and 14.4% (15/104), respectively, and there was no significant difference ( P>0.05). Conclusion:Cefuroxime and clarithromycin containing bismuth quadruplex regimen failed to achieve a satisfactory eradication rate in patients with H. pylori infection and penicillin allergy.
