ObjectiveRetinal vein occlusion （RVO） is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear， current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor （VEGF） agents or corticosteroids， laser photocoagulation， and pars plana vitrectomy. However， these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine （TCM） has unique advantages in the clinical diagnosis and treatment of RVO， and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study， based on the clinical manifestations of RVO， systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI， Wanfang Data， PubMed， and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation， photodynamic therapy， diathermy， intravitreal drug injection， and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations， mainly reflecting disease characteristics. However， they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations， while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research， which make it a scientifically valuable and necessary endeavor.

Objective:In the context of China's cardiovascular disease(CVD)high-risk population screening and intervention project,this study systematically evaluates the applicability of the EQ-5D-5L and SF-6Dv2 instruments among individuals at high risk of CVD.Methods:Convergent validity was assessed using Spearman's correlation coefficient.Measurement agreement was evaluated through intraclass correlation coefficients(ICC)and Bland-Altman plots.Factors influencing utility differences were explored using multiple linear regression analysis.Kruskal-Wallis test and t-test were used to examine discriminant validity.Sensitivity was compared by effect size(ES),relative efficiency(RE),and the area under the receiver operating characteristic curve(ROC-AUC).Floor and ceiling effects were also compared.Results:Among 5,415 individuals at high risk of CVD,the two instruments showed moderate overall correlation and acceptable convergent validity,but dimension-specific correlations were weak,and measurement consistency was low(ICC=0.367).Both instruments effectively distinguished different health states,yet the SF-6Dv2 demonstrated superior sensitivity and a milder ceiling effect.Conclusion:When measuring the health utility value of CVD patients,scale selection should be cautious,especially for high-risk groups,and SF-6Dv2 is more appropriate.

Objective To explore the correlation between serum hypoxia-inducible factor-1α(HIF-1α)levels and cerebral microbleeds(CMBs)and cognitive impairment and to assess the predictive value of HIF-1α for CSVD-related cognitive impairment.Methods A total of 104 patients with CSVD who attended the Department of Neurology,First Affiliated Hospital of Xinxiang Medical University from June 2022 to November 2023 were enrolled.All enrolled patients were subjected to basic statistics,cranial nuclear magnetic resonance examination,cognitive function assessment,and serum HIF-1α test,and the number and location of CMBs were counted.Based on the above data the enrolled patients were grouped.The correlation between HIF-1α and cognitive function and CMBs was studied the influencing factors of CMBs and cognitive impairment were analyzed,and the predictive value of HIF-1α on the occurrence of cognitive impairment was evaluated.Results There were statistically significant differences in HIF-1α levels and cognitive function among different CMBs groups.Serum HIF-1α levels were significantly negatively correlated with overall cognitive function,visuospatial and executive function,attention,and delayed recall,and serum HIF-1α was positively correlated with the number of CMBs.HIF-1α may be a risk factor for CMBs and cognitive impairment associated with CSVD,and serum HIF-1α has potential in predict the cognitive impairment caused by CSVD.Conclusion Serum levels of HIF-1α were associated with the number of CMB and CSVD-related cognitive impairment,and serum levels of HIF-1α may have a predictive value for CSVD-related cognitive impairment.

As the base of the three-tier rural health service network,primary health-care institutions are facing major bottlenecks,such as mismatches with residents'health service needs,shrinking capacity and serious patient losses.The formation of supply and demand service'stickiness'is a key path to promote patient primary care,maintain the sustainable development of the primary health service system,and improve the health of rural residents from a micro perspective,and it is also an important means to address the many challenges of the development of rural primary health care in the new era.Through the case study of X Township Health Center in Qianjiang District,Chongqing,this study found that the health centre was once caught in the difficulties of patient outflow,backward assessment and development restrictions,but in recent years,the institution has turned passivity into initiative,and gradually formed the service'stickiness'between supply and demand by optimizing the service contact process and improving the perceived quality of the residents.The formation of supply and demand'stickiness'is not only conducive to the retention of patients and the enhancement of health management,but also increases the income of primary health care institutions and promotes their sustainable development,which provides valuable practical experience for the transformation and development of primary health care.

Objective:To analyze the factors associated with long-term survival after radical resection of hepatitis B virus(HBV)-associated hepatocellular carcinoma(HCC),and to construct random forest and Cox regression models,to evaluate the two models.Methods:A total of 368 patients with HBV-infected HCC who underwent radical resection were selected retrospectively.These patients were categorized as having a good prognosis(n=266)or a poor prognosis(n=102)based on their survival and mortality status.Univariate and Cox regression analysis were used to identify fac-tors that predict poor prognosis in HCC patients after surgery,and Cox regression and random forest prediction models were constructed and evaluated.Results:There were significant differences in smoking history,Child-Pugh classifica-tion,cirrhosis,microvascular invasion,TNM staging,tumor capsule integrity,platelet-to-lymphocyte ratio(PLR),regular antiviral therapy,HBV-DNA load,alpha-fetoprotein(AFP),neutrophil-to-lymphocyte ratio(NLR),systemic immune in-flammatory index(SII),and albumin-to-globulin ratio(AGR)between the two groups(P<0.05);Cox regression showed that cirrhosis,microvascular invasion,regular antiviral treatment,HBV-DNA load,NLR,PLR,SII,and AGR were related factors that negatively affected the prognosis of patients with HBV-infected HCC after surgery(P<0.05),with an AUC of 0.870 for predicting prognosis;the importance ranking obtained by the random forest model was HBV-DNA load,cirrho-sis,regular antiviral therapy,microvascular invasion,NLR,PLR,AGR,and SII,with an AUC of 0.926 for predicting prog-nosis;the AUC predicted by the random forest model was greater than that predicted by the Cox regression model(Z=2.411,P=0.016).Conclusion:HBV-DNA load,cirrhosis,regular antiviral therapy,microvascular invasion,NLR,PLR,AGR,and SII are factors that affect the poor prognosis of patients with HBV-related HCC after surgery.The random for-est prediction model constructed based on these factors has high predictive value and is superior to the Cox regression prediction model.

OBJECTIVE To evaluate the current status of bacterial contamination control and prevention measures and construction of quality control laboratory in Chinese blood station,and find out the problems and put forward the improvement suggestions.METHODS A total of 41 questionnaires were sent out for performance comparison by secretariat of working group of Chinese blood collection and supply institutions from May 2024 to Jun.2024,and 40 questionnaires were received(14 blood centers and 26 central blood stations),39 of which were valid.The questionnaire survey covered four aspects,including disinfection and surveillance,construction of quality control laboratory,sterility test for blood component and monitoring of blood transfusion reactions.The data were pro-cessed through itemized statistics and descriptive analysis.RESULTS Totally 84.62％of the blood stations used io-dine-containing disinfectants for arm disinfection of the blood donors,and the monthly monitoring was the primary frequency.Among the quality control laboratories,43.59％were registered as biosafety level 2,while 35.90％lacked biosafety registration.As for the pressure settings of the laboratories,64.10％were under normal pres-sure,15.38％under negative pressure and 17.95％under positive pressure.In the sterility test,the utilization rate of ultra clean operating tables and biological safety cabinets was 48.72％,the blood stations that did not have the indoor quality control accounted for 79.49％,and only 35.90％participated the external quality assessment.Regarding the approaches to confirm the positive result,25.64％of the blood stations adopted the re-peated tests,and 15.38％adopted the combination with positive culture bottle.The shortage of fund was the ma-jor restricted factor for the sterility test,and the confirmation of positive result was the fundamental difficulty.The blood stations with the feedback of insufficient transfusion reactions reported from hospitals ac-counted for 53.85％,while the blood stations that encountered suspected bacterial transfusion reactions with nega-tive culture results accounted for 25.64％.CONCLUSIONS The infeciton control and prevention measures and the construction of quality control laboratory vary significantly in Chinese blood stations.The incomplete biosafety registration,non-standardized sterility test operation and weak surveillance of blood transfusion reactions are the major existing problems.It is suggested that the investment should be increased to push forward the standardi-zation and complete the laboratory biosafety system,and a hospital-blood station closed loop coordination mecha-nism should be established so as to raise the blood safety.

This study draws on embedding theory and incentive mechanism theory to construct a multi-dimensional framework for analyzing the integration of county-level health insurance into primary healthcare.Using Qianjiang District,Chongqing,as a case study,it analyses how horizontally bundled funding and service transformation embed insurance into local health governance.The study finds that health insurance is embedded into primary governance through a systemic process driven by values,shaped by social structures,and supported by institutions,involving the reconfiguration of resources,relationships,and interests.Establishing primary care groups as budget units improves alignment between payment and service needs;linking budget limits,surplus incentives,and performance feedback strengthens provider motivation;and coordinated inter-agency mechanisms facilitate integration of fund management and service delivery.

Objective:To evaluate the cost-effectiveness and impact on mortality of health management services for the elderly aged 65 years and older in national essential public health service project.Methods:Based on the data of county-level medical institutions in Henan Province from 2019 to 2024,the Random Forest Method was used to construct a counterfactual framework to predict the hospitalization expenses under the unmanaged scenario,and then the cost-benefit ratio(BCR)and net income were calculated.Time-dependent Cox proportional hazards model was used to evaluate the effect of health management on all-cause mortality and cardiovascular and cerebrovascular disease mortality in the elderly.Results:A total of 962 955 elderly patients were included,451 119(46.85%)were included in the management group.The average hospitalization cost of the management group was significantly lower than that of the non-management group(P<0.05).Except for 2020-2021,BCRS in 2019 and 2022-2024 were 6.34,2.05,4.45 and 6.60,respectively.The risk of all-cause death was reduced by 76.96%,and the risk of cardiovascular and cerebrovascular death was reduced by 75.57%in the elderly patients included in the management group compared with those not included in the management group.Suggestions:It is necessary to establish a health outcomes-based evaluation system and promote the transformation and upgrading of the service model from single chronic disease management to"integrated health services with multi-disease management".

Objective:To investigate the selection preference and heterogeneity of intervention measures for high-risk population of Cardiovascular Disease in rural areas,and to provide new empirical evidence and path reference for evidence-based CVD intervention strategies.Methods:Using cluster sampling method,a discrete choice experiment was designed to conduct an offline survey on 345 CVD high-risk subjects in one of the CVD high-risk screening sites in Hubei Province.Mixed logit model was used for data analysis.Results:The attributes of"Primary medical staff+County-level medical staff+Experts above county-level","Monthly or longer","Non-drug intervention","Drug intervention+non-drug intervention","One hour",all significantly increased the probability of high-risk population to choose the project,and"Online"mode and"Personalized service package"will significantly reduce the probability of respondents to choose a solution,there were significant differences in the selection preferences of high-risk population with different gender,age,education level,income level and health status.Conclusion:The rural CVD high-risk population obviously prefer the intervention model with high level of service subject,off-line implementation,low frequency,medium intensity,non-drug intervention or combined with drug intervention,and free basic service content.It is necessary to explore a more efficient and suitable intervention scheme for CVD in rural high-risk population according to the demand-side preference and its heterogeneity.
