Objective:To establish a health economics evaluation-based adjustment mechanism for the medical insurance fund package in compact county-level medical community.Methods:A health risk assessment system was designed,with weights determined using the Delphi method.Population health risks were evaluated via rapid assessment methods to calculate health risk scores for each county(city,district),which were then used to determine the medical insurance fund package adjustment amount.Results:The county-level health risk evaluation index system encompassed four dimensions:health risk influencing factor,health protection resource,population health risk,and health level.Through information collection and field surveys,health risk scores for counties(cities,districts)in a case prefecture-level city were obtained,serving as a tool for allocating medical consortium package adjustment funds.Conclusion:The health economics evaluation-based medical insurance fund adjustment mechanism enhances the equity of total medical insurance fund allocation,activates the incentive role of medical insurance in healthcare delivery,and transmits intervention pressure to reduce residents'health risks to public management departments at the county level.This approach realizes mutual benefits among medical insurance,residents,and healthcare providers.

Objective To explore the value of a clinical diagnostic model of heart failure(HF)based on disulfidptosis-related genes.Methods The differentially expressed disulfidetosis-related genes from the training set of Gene Expression Omnibus Series(GSE)57345 were obtained,and then analyzed with Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)en-richment analysis,and Metascape disease enrichment analysis.Six male C57BL/6J mice were ran-domly divided into control group(intraperitoneal injection of normal saline)and HF group(intra-peritoneal injection of isoproterenol),with 3 mice in each group.Real-time quantitative PCR was applied to detect the expression levels of key genes.Results GO enrichment analysis revealed that the differentially expressed disulfidetosis-related genes were mainly involved in platelet aggrega-tion and other aspects.KEGG showed they were significantly enriched in tight junctions,vascular smooth muscle contraction and other signaling pathways.Metascape enrichment analysis indicated that these genes were mainly related to focal glomerulosclerosis,glomerular disease,platelet dis-ease,tumor infiltration,nephrotic syndrome and other diseases.The HF group had significantly higher heart weight-to-body weight ratio,and lower ejection fraction,fractional shortening,cardiac output and stroke volume than the control group(P＜0.05,P＜0.01).The cardiac mRNA levels of BNP and MYH10 were significantly higher[1.026±0.501 vs 0.686±0.187,P=0.038;1.469(1.782,2.670)vs 0.360(0.786,1.117),P=0.000],while those of MYL6 and TLN1 was obviously lower(0.575±0.105 vs 1.000±0.202,P=0.027;0.429±0.114 vs 1.000±0.109,P=0.000)in the HF group than the control group.Conclusion Our constructed HF diagnostic model has better di-agnostic performance.

Objective:This study aims to clarify the role of family and community health environments in improving the health status of elderly patients with chronic diseases,and provide recommendations and references for optimizing and enhancing chronic disease management capabilities.Methods:Based on data from the 2018 China Health and Retirement Longitudinal Study(CHARLS),this study analyzes a sample of 9,388 elderly patients with chronic diseases.A hierarchical linear model(HLM)is employed to examine the effects of family and community health environments on chronic disease management outcomes,as well as their variations across urban-rural settings and disease types.Results:The findings indicate that a supportive family health environment significantly improves both self-rated health(β=0.097,P<0.001)and disease control outcomes(β=0.033,P<0.05)among elderly patients with chronic diseases.In contrast,community health environments contribute positively only to self-rated health(β=0.062,P<0.001)but do not significantly affect disease control outcomes.Moreover,no moderating effect of community health environments was observed on the relationship between family health environments and either self-rated health or disease control.The effects of family and community health environment on self-rated health and control results were different between urban and rural areas,while the effects of family health environment on control results were different in disease types.Conclusion:The explanatory power of the family health environment on the health status of elderly patients with chronic diseases is higher than that of the community health environment.However,the two have not been effectively integrated.It is recommended to incorporate the health needs of elderly patients with chronic diseases into the optimization of healthy family construction and to establish a four-in-one comprehensive chronic disease management system involving"patients,families,communities,and primary healthcare institutions."new models for chronic disease management should be explored and innovated.

AIM To study the effects of total flavonoids of Dracocephalum Moldavica L.(TFDM)on reducing the inflammatory response of RAW264.7 macrophages induced by ox-LDL via the nuclear factor κB(NF-κB)/NOD-like receptor 3(NLRP3)signaling pathway.METHODS The RAW264.7 macrophages cultured in vitro were divided into the normal group,the model group(50 μg/mL ox-LDL),the TFDM group(100 μg/mL TFDM+50 μg/mL ox-LDL),the NF-κB inhibitor group(10 μmol/L Bay11-7821+50 μg/mL ox-LDL)and the TFDM+NF-κB inhibitor group(100 μg/mL TFDM+10 μmol/L Bay11-7821+50 μg/mL ox-LDL).The cells had their viability assessed by CCK-8 method;their ROS expression detected by the ROS kit;their mRNA expressions of NF-κB p65,NLRP3,Caspase-1,IL-18 and IL-1β detected by RT-qPCR;their protein expressions of NF-κB p65,IκBα,NLRP3,pro-Caspase-1,Caspase-1,IL-18 and IL-1β by Western blot;their protein expressions of NF-κB p65 and NLRP3 detected using immunofluorescence method.RESULTS Compared with the normal group,the model group showed increased ROS expression(P＜0.01);increased mRNA expressions of NF-κB p65,NLRP3,Caspase-1,IL-18 and IL-1β(P＜0.05,P＜0.01);decreased protein expressions of IκBα and cytoplasmic NF-κB p65(P＜0.01);increased protein expressions of nuclear NF-κB p65,NLRP3,Caspase-1,IL-1 β and IL-18(P＜0.01);and increased fluorescence intensity of NF-κB p65 and NLRP3(P＜0.01).Compared with the model group,the groups intervened with either TFDM or TFDM+inhibitor displayed decreased ROS expression(P＜0.01);the groups administrated with TFDM or NF-κB inhibitor,or TFDM+inhibitor showed decreased mRNA expressions of NF-κB p65,NLRP3,Caspase-1,IL-18 and IL-1β(P＜0.05,P＜0.01),increased protein expressions of IκBα and cytoplasmic NF-κB p65(P＜0.05,P＜0.01),decreased protein expressions of nuclear NF-κB p65,NLRP3,Caspase-1,IL-1β and IL-18(P＜0.05,P＜0.01),and decreased fluorescence intensity of NF-κB p65 and NLRP3(P＜0.01).There existed no significant group difference between the TFDM group and the NF-κB inhibitor group(P＞0.05).The TFDM+inhibitor group demonstrated decreased mRNA expressions of IL-1βand IL-18(P＜0.05),increased IκBα protein expression(P＜0.05),decreased protein expressions of nuclear NF-κB p65,NLRP3,Caspase-1,IL-1 β and IL-18(P＜0.05),and decreased fluorescence intensity of NLRP3 protein(P＜0.05).CONCLUSION TFDM can inhibit the ox-LDL-induced inflammatory response of RAW264.7 macrophages,and the mechansism may be associated with the reduced ROS expression and inflammatory factors due to the inhibited activation of the NF-κB/NLRP3 signaling pathway.

Objective To evaluate the safety and efficacy of valve-in-valve transcatheter mitral valve replacement(ViV-TMVR)in patients with bioprosthetic valve degeneration who are at high surgical risk.Methods This study is a multi-center,retrospective cohort analysis of 20 consecutive patients who underwent transseptal ViV-TMVR using the Edwards SAPIEN 3 transcatheter heart valve(THV).The primary endpoints include technical success and procedural success,both defined according to the Mitral Valve Academic Research Consortium(MVARC)criteria,as well as mortality and functional change assessed based on New York Heart Association(NYHA)classification at 30-days and six months post-procedure.Clinical follow-up assessments are conducted at 30-days and six months.Results From February 2021 to October 2022,a total of 20 patients with symptoms of bioprosthetic valve degeneration were enrolled across nine sites in China.The patients had a mean age of(73.5±5.5)years,with 85.0％being females and 70.0％classified as NYHA class Ⅲ/Ⅳ.The study achieved a 100.0％technical success rate and a 90.0％procedural success rate finally.All patients remained alive during the 30-day follow-up period.However,six months post-intervention,two patients(10.0％)were re-hospitalized due to heart failure,and sadly,one of them(5.0％)died.None of the patients reported any adverse events related to ViV-TMVR during the follow-up period.Notably,there was a significant improvement in NYHA class compared to baseline(P=0.0004)at six-month follow-ups.Conclusions The transseptal ViV-TMVR technique proved to be highly successful and was associated with significant improvement in NYHA class function.These findings strongly suggest that it serves as a safe and efficient treatment alternative for high-risk patients suffering from bioprosthetic valve degeneration.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.
