OBJECTIVE: To explore the effect of Euonymus alatus on the blood glucose and hemorheology in rat model of Type 2 diabetes mellitus with blood stagnation (DMBS). METHODS: High fat diet with streptozocin was used to establish the rat model of Type 2 diabetes mellitus, followed by the prednisolone and adrenaline muscle injection to obtain DMBS. DMBS rats were divided into a DMBS group (treated with saline gavage), an Euonymus alatus group (treated with Euonymus alatus gavage), and a glybenzoylamide group (treated with glybenzoylamide gavage).A blank group was treated with saline gavage. The experiment lasted 4 weeks, followed by the evaluation of rats' behavior, and detection of fasting blood glucose and hemorheology. RESULTS: Compared with DMBS rats, the symptoms of polydipsia and diuresis in Euonymus alatus rats were improved, with increased body weight (P<0.05), better fur and mental state, increased resistance for being caught, and reduced tongue stagnation. Compared with DMBS group, though body weight increased, resistance for being caught decreased in the glybenzoylamide group with bad fur and mental state,and tongue stagnation. As to the fasting blood glucose, there was significant difference between the Euonymus alatus group and the DMBS group (P<0.05). As to the hemorheology, including whole blood viscosity (shear rates 1,5,50, and 100 s(-1)), plasma viscosity, and hematocrit, the Euonymus alatus rats had a better efficacy than DMBS rats and glybenzoylamide rats (P<0.05 or P<0.01). CONCLUSION Euonymus alatus can reduce the fasting blood glucose of DMBS and improve blood stagnation.

Objective This study aims to examine the potential mechanism of Shenfu Yixin Granules on heart failure(HF)based on network pharmacology,molecular docking,and experimental verification.Methods(1)The active components of herbs in Shenfu Yixin Granules were screened and retrieved through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP).PubChem database and Swiss Target Prediction platform were used to predict targets.GeneCards and OMIM databases were used to screen HF-related targets.The intersection of active ingredient targets of Shenfu Yixin Granules and HF-related targets was performed by using Venny 2.1.0 platform to obtain common targets,which were the potential targets for anti-HF effect of Shenfu Yixin Granules.The potential targets were imported into the STRING database to construct a protein-protein interaction(PPI)network and screen the core targets of Shenfu Yixin Granules for the treatment of HF.GO functional and KEGG pathway enrichment analysis of potential targets were carried out by using DAVID database.AutoDock Vina software was used for molecular docking validation of key active ingredients and core targets.(2)SD rats were randomly allocated into sham operation group,model group,Shenfu Yixin Granules(5.28 g·kg-1)group,and positive control group(sacubitril-valsartan,20.8 mg·kg-1),with eight rats in each group.A rat model of HF after myocardial infarction was established by ligating the left anterior descending coronary artery.The rats were subsequently administered orally with the corresponding drugs once daily for a period of four weeks.Cardiac function including left ventricular ejection fraction(LVEF)and left ventricular fraction shortening(LVFS)in rats was assessed by echocardiography.Additionally,the histopathological alterations in rat heart tissue were examined using hematoxylin-eosin(HE)staining and Masson staining.The serum levels of brain natriuretic peptide(BNP),artial natriuretic peptide(ANP),and aldosterone(ALD)were determined by enzyme-linked immunosorbent assay(ELISA).Furthermore,real-time quantitative PCR and Western Blot were employed to detect mRNA and protein expressions of CAV1、F2 and MAPK1 in heart tissue.Results(1)A total of 210 active ingredients and 1 196 targets of Shenfu Yixin Granules,as well as 801 HF-related targets were obtained.Venny 2.1.0 platform was used to acquire 97 potential targets(common targets)of Shenfu Yixin Granules for the treatment of HF.Key active ingredients,such as quercetin,luteolin,arachidonic acid,kaempferol,and tanshinaldehyde were screened by"drugs-active ingredients-disease-targets"network analysis.The core targets including MAPK1、F2、CAV1、EDN1 and GJA1 were identified through PPI network analysis.The potential targets are mainly concentrated in multiple biological processes,namely,the positive regulation of gene expression,cardiac development,and the positive regulation of MAPK cascade,and involve multi key pathways including MAPK signaling pathway,HIF-1 signaling pathway and PI3K/Akt signaling pathway etc.Good binding activities were observed between MAPK1,CAV1,EDN1,F2 and quercetin,luteolin,kaempferol,tanshinaldehyde,as well as MAPK1,F2 and arachidonic acid.(2)Compared with sham operation group,LVEF and LVFS of rats significantly reduced(P＜0.01),heart mass index obviously increased(P＜0.05)in the model group.Myocardial tissue appears obvious pathological damage,and the degree of interstitial fibrosis was serious.The collagen volume fraction of the heart significantly increased(P＜0.01).The levels of serum BNP,ANP and ALD significantly increased(P＜0.01).The mRNA and protein expressions of CAV1、F2 and MAPK1 in heart tissue significantly increased(P＜0.05,P＜0.01).Compared with the model group,LVEF and LVFS of rats obviously increased(P＜0.01),but the decrease in heart mass index was not significant(P＞0.05)in Shenfu Yixin Granules group and positive control group.The pathological damage in myocardial tissues was significantly improved,the degree of interstitial fibrosis was significantly reduced.The collagen volume fraction of the heart significantly decreased(P＜0.01).The levels of serum BNP,ANP and ALD significantly decreased(P＜0.01).The mRNA and protein expressions of CAV1、F2 and MAPK1 in heart tissue significantly decreased(P＜0.05,P＜0.01).Conclusion Shenfu Yixin Granules may improve heart function and myocardial fibrosis in heart failure rats through the interaction between the active ingredients(quercetin,luteolin,arachidonic acid,kaempferol,and tanshinaldehyde)and targets(MAPK1,F2,CAV-1,and EDN1),so as to regulate MAPK signaling pathway and PI3K/Akt signaling pathway.

Objective To investigate the independent influences on the occurrence of ICU Acquired Weakness(ICU-AW)in elderly patients undergoing third-and fourth-level surgeries,to construct a prediction model and draw a column-line diagram,and to internally validate the model.Methods A convenience sampling method was used to select 186 elderly patients undergoing tertiary and quaternary surgeries who were hospitalized in 3 tertiary A hospitals in Beijing from May to December 2022 as the study subjects.Single-factor and multifactor logistic regression were used to analyze the risk factors for ICU-AW in elderly patients undergoing third-and fourth-degree surgeries.A risk prediction model was established and the model was visualized by drawing a column-line diagram,and the receiver operator characteristic curve(ROC)and the Hosmer-Lemeshow tests were applied to verify the predictive effect of the model.Results ICU-AW occurred in 40 of 186 cases in the modeling group,with an incidence rate of 21.5％.The results of univariate analysis showed that the 2 groups of preoperative physiology score and surgical severity score included in the physiology and surgical severity scoring system,age,presence of cardiac disease,hemoglobin(within 24 h of admission to the ICU),blood urea nitrogen(within 24 h of admission to the ICU),blood creatinine(within 24 h of admission to the ICU),presence of braking,mode of establishment of mechanical ventilation,presence of nutritional therapy,number of sedative or analgesic drugs used,whether vasoactive drugs were used,whether diuretics were used,and the level of hemoglobin,blood urea nitrogen and blood creatinine within 24 h after admission to ICU the difference is statistically significant(P＜0.05).The results of multifactorial logistic regression analysis showed that preoperative physiology scores included in the physiology and surgical severity scoring system,the presence of cardiac disease,the presence of braking,the presence of nutritional therapy,and the number of sedative or analgesic medications used were the predictors of the occurrence of ICU-AW in elderly patients undergoing third-and fourth-degree surgeries(OR were 1.364,2.344,5.568,5.823,1.109,all P＜0.05).The above 5 factors were plotted as independent variables in a column-line graph,and the area under the ROC curve of the model was 0.859(95％CI 0.793～0.924),with an optimal critical value of 0.156,a sensitivity of 0.875,a specificity of 0.705,and a Hosmer-Lemeshow goodness-of-fit test of x2=3.906,P=0.865,Brier score of 0.109,and a decision analysis curve indicating that patients could benefit.Conclusion The predictive effect of the constructed model is good,and it can be used as a reference for early and rapid identification of the risk of ICU-AW in elderly patients undergoing third-and fourth-degree surgeries by clinical staff,and timely provision of preventive intervention programs.

Objective:To carry out high-risk foot examination and grading combined with two examination methods for inpatients with type 2 diabetes, and explore the influencing factors of the occurrence and development of high-risk foot, and investigate their foot care behavior status.Methods:From July 2021 to January 2022, 409 patients with diabetes who were admitted to the Department of Endocrinology, Department of Geriatrics, Department of Cardiology, Urology Surgery and Department of Ophthalmology of Xuanwu Hospital of Capital Medical University were selected as research subjects by convenience sampling. The General Information Questionnaire, Standardized Process of At-risk Foot Screening and Stratification for Diabetic Patients, InIow's Screening for the High-Risk Diabetic Foot: A 60-Second Tool, and Foot Care Behavior Questionnaire for Diabetic Patients. Single factor analysis and Logistic regression analysis were used to explore the factors influencing the occurrence and development of high-risk foot in type 2 diabetes patients. A total of 409 questionnaires were distributed, and 392 valid questionnaires were collected, with an effective response rate of 95.8% (392/409) .Results:Among 392 patients, the detection rate of high-risk diabetic foot (HRDF) was 76.3% (299/392), and the proportion of high-risk foot grade 2 was the largest (193). Age ( OR=1.042, P<0.01) and years of hypertension ( OR=1.030, P<0.05) were independent influencing factors for the occurrence of HRDF, with statistically significant differences. Taking the high risk foot grade 3 as a reference, cerebrovascular disease [ OR=16.408, 95% CI (1.323, 203.417) ], diabetes course [ OR=1.066, 95% CI (1.008, 1.128) ], education level in middle school [ OR=0.180, 95% CI (0.056, 0.581) ], education level in primary school and below [ OR=0.126, 95% CI (0.019, 0.841) ] were independent influencing factors for the progress of high risk foot. The foot care behavior of high-risk foot patients with high risk levels was not superior to that of patients with low risk levels. Conclusions:The combination of the two screening methods can meet the examination needs of clinical and nursing medical staff for inpatients with type 2 diabetes. Emphasizing the influencing factors of HRDF occurrence and development can provide reference for early identification of high-risk foot.
