Objectives:To assess the impact of intravascular ultrasound(IVUS)guidance for drug-eluting stent(DES)implantation on the long-term outcomes in coronary artery disease(CAD)patients with chronic kidney disease(CKD).Methods:A retrospective study was conducted on 1 800 CAD and CKD patients who underwent coronary DES implantation at Nanjing First Hospital from January 2018 to December 2022.Patients were divided into IVUS-guided group(IVUS group,n=333)and angiography-guided group(angiography group,n=1 467).Propensity score matching(PSM)was performed at a 1:2 ratio to adjust for differences in baseline clinical and angiographic characteristics between the two groups.Major adverse cardiovascular events(MACE),including cardiac death,target vessel myocardial infarction,and clinically driven target vessel revascularization,were evaluated over a 2-year follow-up.Cox proportional hazards regression was performed to identify independent predictors of MACE.Results:After propensity score matching,333 patients in the IVUS group were matched with 666 patients in the angiography group.Following matching,there were no significant differences in clinical characteristics and angiographic data between the two groups(all P>0.05).Regarding procedural data,IVUS group had a higher number of stents implanted,longer total stent length,larger average stent diameter,more frequent use of post-dilation balloons,larger post-dilation balloon diameter,and greater contrast agent usage(all P<0.05).MACE rate was significantly higher in the angiography group than that in the IVUS group(23.9%vs.18.0%,P=0.037).The difference was mainly attributed to a higher rate of cardiac death in the angiography group(16.1%vs.10.8%,P=0.013).Additionally,patients in angiography group had a significantly higher all-cause mortality rate compared to IVUS group(19.7%vs.13.8%,P=0.022).Multivariate cox regression analysis showed that IVUS guidance(HR=0.73,95%CI:0.55-0.99,P=0.042)was an independent protective factor,while hypertension(HR=1.60,95%CI:1.13-2.26,P=0.008),type 2 diabetes(HR=1.56,95%CI:1.19-2.05,P=0.001),acute coronary syndrome(HR=1.92,95%CI:1.12-3.30,P=0.018),and moderate to severe calcification(HR=1.55,95%CI:1.18-2.04,P=0.002)were independent risk factors for MACE at 2 years after DES implantation in CKD patients.Conclusions:Patients with CAD and CKD,IVUS-guided DES implantation is associated with a reduced risk of MACE and all-cause mortality at 2 years post-procedure compared to coronary angiography-guided implantation.

Objective:To investigate the association between the triglyceride-glucose(TyG)index and the incidence and mortality of cardiovascular disease(CVD)in a large population-based cohort.Methods:Participants aged 40-79 years without a history of CVD at baseline were drawn from the CHi-nese Electronic health Records Research in Yinzhou(CHERRY)study between January 1,2010,and May 31,2020.The TyG index was calculated using baseline triglyceride and fasting blood glucose.Cox proportional hazards models were used to assess the association between the TyG index and the composite outcome of CVD(incidence and mortality),adjusting for age,gender,education,region,smoking sta-tus,body mass index,systolic blood pressure,and total cholesterol.Hazard ratios(HR)and 95％confi-dence intervals(CI)were calculated.Nonlinear associations between the TyG index and CVD were fur-ther evaluated using restricted cubic splines,and subgroup analyses by gender and age were conducted to explore potential differences.Results:A total of 226 406 individuals were included,with a mean age of(55.0±9.7)years at baseline,46.8％of whom were men,and a median TyG index of 8.68.Over a median follow-up of 7.99 years,9 815(4.34％)participants experienced CVD incidence or mortality.After adjusting for age,gender,education,region,smoking status,body mass index,systolic blood pressure and total cholesterol,the risk of CVD increased with higher TyG index levels(P＜0.001).The risk in the highest TyG quartile(TyG＞9.10)was 42％higher than in the lowest quartile(TyG ≤8.32)(HR=1.42,95％CI:1.34-1.51).Individuals under 60 years had a higher HR for CVD compared with those aged 60 years and above(HR:1.71 vs.1.27,P＜0.05).Restricted cubic spline analysis revealed a reverse L-shaped association between the TyG index and CVD risk in the overall population(P＜0.001 for nonlinear trend),with risk increasing after the TyG index exceeded 8.67.However,the threshold varied by gender,with a lower threshold in women(8.51)than in men(8.67).Conclusion:A significant nonlinear relationship was revealed between the TyG index and CVD risk,with a threshold effect.The risk of CVD increased once the TyG index surpassed a certain threshold,with a lower threshold in women than in men.These findings suggest that cardiovascular risk prediction and interven-tions based on the TyG index should be gender-stratified,and early intervention for individuals under 60 years old might have important public health implications.

Objective:To explore the effectiveness and safety of different anticoagulation strategies during continuous blood purification (CBP) treatment,providing a reference for anticoagulation strategies in critically ill children undergoing CBP.Methods:A retrospective study was conducted,including children admitted to the PICU of Children's Hospital of Fudan University from January 2019 to December 2024.According to the anticoagulation methods used during CBP treatment,patients were divided into the sodium citrate group and the heparin group.CBP was performed using continuous venovenous hemofiltration or continuous venovenous hemodialysis filtration mode,with a blood flow rate of 3-5 mL/(kg·min),replacement fluid rate of 30-50 mL/(kg·h),and dialysis fluid rate of 20-30 mL/(kg·h).The filter lifespan,28-day all-cause mortality,total length of hospital stay,PICU stay duration,adverse events,and associated costs were compared between the two groups.Results:A total of 221 children were included (105 in the sodium citrate group and 116 in the heparin group),with a cumulative use of 666 filters (284 in the sodium citrate group and 382 in the heparin group).(1) There were no statistically significant differences in general data,including age,sex ratio,underlying diseases,the ratio and duration of invasive mechanical ventilation,vasopressor scores at baseline,and indications for CBP between the two groups (all P>0.05).(2) The filter lifespan was 20(14,32) hours for the sodium citrate group and 21(13,35) hours for the heparin group,with no statistically significant difference between the two groups ( P>0.05); the proportion of accidental downstroke was 2.8% and 6.5%,respectively,with a statistically significant difference ( P=0.029); among the 221 children,86 died,with 38 deaths (35.2%) in the sodium citrate group and 49 deaths (38.9%) in the heparin group,showing no statistically significant difference.(3) The sodium citrate group had a higher incidence of metabolic alkalosis,hypocalcemia,and sodium citrate accumulation (44.4% vs. 1.6%,32.7% vs 9.4%,7.7% vs 0,all P<0.01); the heparin group had a greater proportion of bleeding (6.0% vs. 2.9%) and was more likely to develop heparin-induced thrombocytopenia (10.2% vs. 0, P<0.01).(4) The total hospitalization costs for the sodium citrate group were significantly higher than for the heparin group (200 327 yuan vs. 152 077 yuan, P=0.05); costs related to the use of anticoagulants and monitoring indicators during CBP treatment were also higher in the sodium citrate group (2 479 yuan vs. 682 yuan, P<0.01). Conclusions:Sodium citrate is a safe and effective anticoagulation method for critically ill children undergoing CBP,which can reduce the risk of filter clotting compared to systemic heparin anticoagulation.

Objective:To investigate the current self-compassion levels in hematologic malignant tumor patients and analyze the influencing factors, providing a basis for clinical interventions.Methods:A convenience sampling method was used to select 120 patients with hematologic malignant tumors treated at the First Affiliated Hospital of Wenzhou Medical University from January to December 2022. Clinical data, self-compassion levels, social support, and adult attachment status were assessed using general data questionnaires, the Self-Compassion Scale (SCS) , the Perceived Social Support Scale (PSSS) , and the Experiences in Close Relationship Scale-Short Form (ECR-S) . Pearson correlation analysis was performed to analyze the correlation between SCS scores and PSSS, ECR-S scores. Multiple linear regression analysis was conducted to explore the influencing factors of self-compassion levels.Results:A total of 120 questionnaires were distributed, and 114 valid questionnaires were returned, resulting in an effective response rate of 95.00%. The average SCS score of hematologic malignant tumor patients was (80.54±5.80) . Univariate analysis showed that self-compassion levels differed significantly among patients of different ages, education levels, per capita family monthly income, disease duration, and the first diagnosis or not of hematologic malignant tumors ( P<0.01) . Pearson correlation analysis revealed a positive correlation between SCS scores and PSSS scores ( r=0.659, P<0.001) , and a negative correlation with the attachment anxiety and avoidance dimensions of the ECR-S ( r=-0.152, -0.588, P<0.001) . Multiple linear regression analysis showed that education level, the first diagnosis or not, PSSS score, ECR-S attachment anxiety dimension, and ECR-S attachment avoidance dimension scores entered the regression equation. Conclusions:The influencing factors of self-compassion levels in hematologic malignant tumor patients include education level, the first diagnosis or not, social support level, and adult attachment status. Healthcare providers should strengthen psychological support for patients with low education, disease recurrence/treatment failure, and insecure attachment types, while also improving patients' social support levels to enhance their self-compassion status.

Objectives:To describe the use of antihypertensive, antidiabetic and lipid-lowering drugs, and evaluate the effects on blood pressure, blood glucose and blood lipids controls required by Chinese Guideline on the Primary Prevention of Cardiovascular Diseases (the guideline) in a community-based cohort of individuals at high risk for cardiovascular disease. To analyze the association of the uses of antihypertensive, antidiabetic and lipid-lowering drugs, and the comprehensive control of blood pressure, blood glucose and blood lipids with cardiovascular disease. Methods:From the CHinese Electronic health Records Research in Yinzhou (CHERRY), those who were at high risk for cardiovascular disease and aged 40-75 years as of January 1, 2013 in in Yinzhou District of Ningbo, Zhejiang Province were selected as study subjects. The information about their antihypertensive, antidiabetic, and lipid-lowering drug uses between 2013 and 2015 was collected, and blood pressure, blood glucose, and blood lipid measurements were conducted during the follow-up. The study constructed two kinds of comprehensive scores: the comprehensive medication score based on the guideline requirement for the treatment of hypertension, diabetes and hyperlipidemia, dividing the study participants into the compliancy group and non-compliancy group; and the comprehensive control score based on the guideline requirement for blood pressure, blood glucose, and blood lipids control, dividing the study participants into better control group, moderate control group, and poor control group. Cox proportional hazards regression model was used to analyze the association of the comprehensive medication score and comprehensive control score with cardiovascular disease. The incidence data of cardiovascular disease were collected from January 1, 2015 (baseline time) to August 31, 2020 (follow up end time).Results:A total of 79 734 participants at high risk for cardiovascular disease were included in the study, in whom 68.4%, 27.4%, and 4.2% had 1, 2, or 3 cardiometabolic conditions (hypertension, diabetes, or hyperlipidemia), respectively. In the participants with hypertension, diabetes, and hyperlipidemia from 2013 to 2015, the proportions of those who had two years of medication compliancy records were 66.0%, 67.4%, and 13.9%, respectively. In the hypertension patients, 59.2% had better blood pressure control, in the diabetes patients, 28.7% had better blood glucose control, and in the patients with hyperlipidemia, 27.4% had better blood lipid control. After a median follow-up of 5.66 years, 4 088 cardiovascular disease cases or deaths occurred. After multivariate adjustment, compared with the non-compliancy group, the compliancy group had lower risk for cardiovascular disease ( HR=0.91, 95% CI: 0.85-0.96). Compared with the better control group, the poor control group had an increased risk for cardiovascular disease ( HR=1.67, 95% CI: 1.53-1.81). In the moderate control group, the risk increased significantly in the diabetes patients ( HR=1.29, 95% CI: 1.07-1.56), while no additional risk for cardiovascular disease was observed in non-diabetes patients ( HR=1.06, 95% CI: 0.97-1.16). Conclusions:Compliancy to the medication required by the guideline is associated with lower risk for cardiovascular disease. However, it is still necessary to improve the medication compliancy in people at high risk in primary prevention, especially in the patients with hyperlipidemia, due to their low taking rate of lipid-lowering drugs. Additionally, as the requirement of the guideline becomes more stringent, the management of disease has met more challenges. Notably, diabetes patients who have not met the guideline requirement are at high risk for cardiovascular disease, to whom the disease management should be strengthened.

Objective:To explore the causes of lack of compliance with life care in hematopoietic stem cell transplantation recipients while living alone in the transplant warehouse, and to provide a basis for developing targeted promotion measures.Methods:Using purposive sampling method, from June to December 2023, on-site observations were conducted on the voluntary completion of life care by hematopoietic stem cell transplant patients (with a 30 day observation period) admitted to the Blood Transplantation Center of the First Affiliated Hospital of Wenzhou Medical University. The compliance was calculated after the observation period. Patients with a compliance of less than 80% were selected, and semi-structured interviews were conducted with 17 of them after informed consent. The Colaizzi 7-step analysis method was applied to organize and analyze the interview data.Results:Three core themes on lack of compliance were distilled, namely physical factors impeding compliance (somatic specific symptoms leading to distraction, somatic non-specific symptoms leading to activity intolerance), psychological factors impeding compliance (negative emotions, comfort zone dilemmas, regression phenomena, constraints of personality psychological traits), and cognitive factors impeding compliance (subjective cognitive unperceived benefit, poor modeling resulting in cognitive biases, limited perceived attention) .Conclusions:The behavioral causes of lack of compliance with life care of hematopoietic stem cell transplant patients while living alone in the transplant warehouse are due to multiple factors of the body and mind, among which psychologically mediated mechanisms are key to compliance. Healthcare professionals should pay attention to both the physiological and psychological needs of patients, actively alleviate physical symptoms, appropriately provide psychological care to remove psychological barriers, help them actively seek family and social support, and promote cognitive improvement, thereby improving compliance.

Objective:To establish a highly sensitive indirect competitive ELISA(icELISA)method for detecting ribavirin in chicken.Methods:Based on the obtained monoclonal antibodies against ribavirin,a chessboard test was employed to determine the optimal working concentration of artificial antigen and antibody,and then established an icELISA method.Furthermore,performance of the detection method was evaluated.Results:The established icELISA method has a linear range of 0.44～32.71 ng/ml,IC50 of which was 3.78 ng/ml,and the limit of detection(LOD)was 0.20 ng/ml.Except for specific reaction with ribavirin,there were no cross reactions with other antiviral drugs.Recovery rate of sample spiking was between 91.60%and 100.76%,and coefficient of variation was between 7.29%and 10.63%.Conclusion:A highly sensitive and specific icELISA method for detection of ribavirin has been estab-lished,which can be used to determine the residue of ribavirin in chicken.

Objective:To explore the application of the O-PIRTAS flipped classroom in teaching the course of "developmental psychology".Methods:This study involved second-year undergraduate students majoring in clinical psychology. The 26 undergraduate students enrolled in 2023 who participated in the late adulthood section of the course were selected as the experimental group (O-PIRTAS teaching), while the 25 undergraduate enrolled in 2022 in the same course were selected as the control group (traditional teaching). Assessments were conducted through closed-book tests and questionnaires. The student questionnaire evaluated their theoretical knowledge, class assessment, and class engagement. The teacher questionnaire assessed the completeness of the lecture, logical flow, and student engagement. SPSS 22.0 was used for t test. Results:In the theoretical examination, the experimental group showed significantly higher scores compared to the control group in knowledge application [(13.09±1.59) vs. (10.54±0.77)] and practical problem-solving ability [(8.27±0.57) vs. (6.95±0.32)]. In the questionnaire survey, 24 (92.00%) students in the experimental group expressed recognition of the flipped classroom mode. Teachers reported greater improvement in satisfaction with the classroom performance of the experimental group compared to the control group.Conclusions:O-PIRTAS flipped classroom improves the quality of teaching "developmental psychology", enhances student learning outcomes, and stimulates learning motivation.

Objective:To investigate the therapeutic effects of the copper chelator ammonium tetrathiomolybdate (TTM) on rheumatoid arthritis (RA) in a mouse model.Methods:Twenty-four male dilution brown non-Agoutia/1 mice were randomly divided into 4 groups: a blank control group (Ctrl group, n=6), a collagen-induced arthritis (CIA) + phosphate buffer saline (PBS) treatment group (PBS group, n=6), a CIA+TTM treatment group (TTM group, n=6), and a CIA+Elesclomol treatment group (Eles group, n=6). Eles, a copper ion carrier, served as a control for administration of TTM, a copper ion chelator. One week after treatment, the swelling of mouse paw was observed, and the clinical scoring of the arthritis in mice was evaluated once a week. Paw mechanical pain detection was performed and photographs were taken to observe the severity of paw swelling before the mice were sacrificed. Catwalk gait analysis system was used to evaluate the gait changes in mice. HE and saffron O solid green staining were used to evaluate pathomorphologic changes in the mice knee joints and paws. Immunostaining techniques were used to detect the protein expression of MMP3, CD31, and VEGF in the mice paws. Luminex technology was used to detect alterations in the serum inflammatory factors. Results:Compared with the Ctrl group, in the PBS and Eles groups, the joints were red, swollen and deformed; the arthritis clinical scores were significantly higher; the bone destruction, synovial hyperplasia and inflammatory cell infiltration and pathological changes in the joint tissues were obvious; the expression levels of inflammatory factors, such as serum MCP-1, IL-1 β, IL-9, and IFN- γ, were significantly higher while the expression level of IL-10 was significantly lower. Simultaneously, the expression of CD31 and VEGF factors was significantly enhanced. Compared with the PBS group, in the TTM group, the joint swelling and deformation were significantly improved, the arthritis clinical score was reduced, and the joint bone destruction, inflammatory cell infiltration and synovial hyperplasia were alleviated, and the levels of serum MCP-1, IL-1 β, IL-9 and IFN- γ were significantly decreased while the level of anti-inflammatory factor IL-10 was increased. There was no significant difference in the expression of MMP-3, CD31 or VEGF factors between the CTRL group and the TTM group. Conclusion:TTM can block synovial inflammation, angiogenesis, and bone destruction multiple times by simultaneously targeting multiple inflammatory factors, VEGF factors, and bone destruction mediators, thereby alleviating the pathological damage to the joint tissues induced by CIA in RA mice.

Conclusions:Compliancy to the medication required by the guideline is associated with lower risk for cardiovascular disease. However, it is still necessary to improve the medication compliancy in people at high risk in primary prevention, especially in the patients with hyperlipidemia, due to their low taking rate of lipid-lowering drugs. Additionally, as the requirement of the guideline becomes more stringent, the management of disease has met more challenges. Notably, diabetes patients who have not met the guideline requirement are at high risk for cardiovascular disease, to whom the disease management should be strengthened.
