Objective To analyze the clinical characteristics and risk factors of noninfectious fever after endovascular repair of aortic dilatation diseases, and to explore management strategies. Methods A retrospective analysis was conducted on the clinical data of patients who underwent endovascular aortic repair for aortic dilatation diseases from January 2021 to October 2023. Based on inclusion and exclusion criteria, the enrolled patients were divided into a febrile group and an afebrile group according to the presence of postoperative fever. Clinical data, including demographics and surgical details, were compared between the two groups. Multivariate logistic regression analysis was performed on indicators with P≤0.05 in the univariate analysis, and receiver operating characteristic (ROC) curves were generated to analyze the predictive value of risk factors for postoperative noninfectious fever. Results A total of 305 patients were included in the final analysis. Postoperative noninfectious fever occurred in 75.08% (229/305) of the patients, with 98.25% of cases occurring within the first two postoperative days. The febrile group (n=229) had a median age of 65.0 (IQR: 53.0, 73.0) years with 83.4% males, while the afebrile group (n=76) had a median age of 71.0 (IQR: 65.0, 76.7) years with 84.2% males. Univariate analysis showed that the age, prevalence of coronary heart disease, preoperative statin use, and prevalence of aortic aneurysm were significantly lower in the febrile group compared to the afebrile group. Logistic regression analysis indicated that age, surgical site, disease type, preoperative elevated body temperature, and stent type were significantly associated with noninfectious fever, while preoperative statin use was negatively correlated. ROC curve analysis demonstrated that age, surgical site, preoperative elevated body temperature, and stent type had significant predictive value for postoperative noninfectious fever (P<0.01). Conclusion Noninfectious fever is highly prevalent following aortic repair. The relationship between fever and infection should be comprehensively evaluated based on risk factors and changes in the patient's condition to promote the rational use of antibiotics.

OBJECTIV E To develop the infor mation-based pharmaceutical care pathway of anticoagulant therapy in patients with atrial fibrillation and improve the efficacy and safety of treatment for them. METHODS The“anticoagulant pharmaceutical care”module was developed on the basis of medical intelligent and decision system. Patients with atrial fibrillation were taken pharmaceutical care in the whole anticoagulant treatment by evaluating the thromboembolism and bleeding risks ，pre-reviewing antithrombotic prescriptions ，monitoring efficacy and drug interactions ，and warning adverse reactions. RESULTS A total of 1 228 patients receiving anticoagulant therapy were enrolled. It was found after analysis of their doctor ’s orders that 9.27％ of the patients adjusted the improper antithrombotic therapies ，3.99％ modulated treatments according to the effects of potential drug interactions or the risk of adverse reactions ，and 70.29％ of the wrong prescriptions were intervened successfully. After the information-based pharmaceutical care ，the anticoagulation treatment rate increased from 88.73％ to 97.40％，the rate of patients ’achievements to warfarin’s international normalized ratio in hospital increased from 38.64％ to 66.67％，and the incidence of serious bleeding events decreased from 2.94％ to 0.37％ （P＜0.05）. CONCLUSIONS The information-based pharmaceutical care path of anticoagulant therapy achieved comprehensive ，efficient and accurate management of patients with atrial fibrillation ，and improved the rationality ，effectiveness and safety of anticoagulant therapy.

Objective To study the antidepressant-like effect of Butanol Extract from Stevia (BEFS) and its possible corresponding mechanisms.Methods Forty-five mice were randomly divided into control group,model group,model + Fluoxetine group,model + BEFS-3 g/kg group and model + BEFS-6 g/kg group.The chronic unpredictable mild stress(CUMS) for 3 weeks was used to make up depressive animal model.It was based on body weight,crossing numbers,rearing numbers and sucrose preference to assess whether the model was a success.After continuous lavage giving BEFS and fluoxetine for 2 weeks and subsequent behavioral test,the mRNA transcription of Single immunoglobulin interleukin-1 receptor-related molecule (SIGIRR) and nuclear factor kappa-B (NF-κB) in liver tissue of mice were detected by using quantitative real time-PCR.Results Three weeks after CUMS,behavior parameters were significantly decreased in mice exposed to CUMS compared with control group[(17.28 ±0.49) g vs (22.47 ± 0.82) g,P =0.000;(43.35 ± 1.68) scores vs (125.25 ± 3.07) scores,P =0.000;(3.92 ± 0.18) scores vs (15.92 ± 1.78) scores,P =0.000;(49.39 ± 2.05) ％ vs (67.18 ± 4.46) ％,P =0.001].However,2 weeks after dosing,body weight,crossing numbers,rearing numbers and sucrose preference were (19.03 ± 0.44) g,(70.50 ± 6.56) scores,(3.08 ± 0.77) scores and (41.27 ± 7.59) ％,respectively in model group.Compared to model group,behavior parameters of BEFS (3 and 6 g/kg BEFS) groups were significantly increased [BEFS-6 g/kg group:(24.42 ± 1.46) g,(99.75 ± 5.07) scores,(13.08 ± 1.60) scores,(64.31 ± 1.92) ％,all P ＜ 0.05;BEFS-3 g/kg group:(23.82 ± 1.72) g,(91.67 ± 5.69) scores,(6.92 ± 1.05) scores,(59.56 ± 5.31) ％,respectively,all P ＜ 0.05].Correspondingly,BEFS could reverse the mRNA expression of SIGIRR lowering and NF-κB rising in the liver of mice exposed to CUMS(BEFS-6 g/kg group:1.208 1 ± 0.102 2,1.437 7 ± 0.352 9;BEFS-3 g/kg group:0.768 0 ± 0.108 6,2.186 2 ± 0.203 8,all P ＜ 0.05).Conclusions BEFS can remarkably improve depression-like behaviors in CUMS mice and its antidepressant activity is mediated,at least in part,by upregulating SIGIRR and downregulating NF-κB in the liver.
