Objective:To analyze the data changes of tertiary hospitals,secondary hospitals and primary healthcare institutions in Shandong before and after the reform of Dignosis Related Group(DRG)/Diagnosis-Intervention Packet(DIP)payment method,and to explore the impact of the reform of DRG/DIP payment method on the effect of hierarchical diagnosis and treatment.Methods:Data were collected from 16 cities in Shandong Province for a total of 18 quarters in the first half of 2019-2023,including the percentage of expenditure of the health insurance fund,the percentage of discharges,and the sub-average hospitalization cost.Spatial panel models were constructed to conduct σ-convergence and absolute β-convergence analyses.Results:The convergence analysis showed that the inter-regional differences in the percentage of discharges,the percentage of fund expenditure and the average hospitalization cost of tertiary medical institutions were reduced;the regression coefficients of the three indicators in the absolute convergence analysis were significantly negative(β＜0,P＜0.01),indicating that the level of hierarchical diagnosis and treatment in various cities and regions has been equalized.Conclusion:The reform of DRG/DIP payment method reform has effectively optimized the allocation of medical resources in Shandong and reduced regional differences.It is needed to strengthen the effect of the payment method reform,reinforced the incentive of primary care and construct a full-cycle health management-oriented health insurance system in the future.

BACKGROUND AND PURPOSE: Both genetic factors and smoking are associated with ischemic stroke (IS) risk. However, little is known about the potential interaction of these factors. We aimed to assess whether smoking and a positive family history interact to increase the risk of IS. METHODS: The nationwide prospective study recruited 210,000 men and 300,000 women in 2004 to 2008 at ages 30 to 79 years. During 9.7 years of follow-up, we documented 16,923 and 20,656 incident IS cases in men and women without major chronic diseases at baseline, respectively. Multivariable Cox regression models were used to examine associations between family history and IS. Likelihood ratio tests were used to test the smoking-family history interactions on IS. RESULTS: About 67.8% (n=135,168) of men ever smoked regularly compared with 2.7% (n=7,775) of women. Among men, a significant interaction between family history and smoking on IS was observed (P for interaction=0.03), with more pronounced association between family history and IS among ever-regular smokers (hazard ratio [HR], 1.21; 95% confidence interval [CI], 1.16 to 1.27) than among never-smokers (HR, 1.11; 95% CI, 1.01 to 1.23). The association between family history and IS among ex-smokers after more than 10 years of cessation (HR, 1.01; 95% CI, 0.85 to 1.20) appeared similar to that among never-smokers. Among women, a similar but not significant interaction between family history and smoking on IS was observed. Ever-regular smokers who had a family history of stroke had the highest risk of IS. CONCLUSIONS: Among Chinese men, the association of family history with IS was accentuated by smoking, and such accentuation tended to be lowered by cessation.

Objective To systematically evaluate the relationship between atherosclerotic renal artery stenosis (ARAS) and cor‐onary artery disease (CAD) and peripheral arterial disease (PAD) .Methods We gathered all case‐control studies about the correla‐tion of ARAS with CAD and PAD in the following databases:Cochrane library ,PubMed ,EMBASE ,Web of science until April , 2014 .Two reviewers extracted all relevant datas from the screened documents independently according to exclusion and inclusion criteria ,RevMan 5 .2 software were used to conduct Meta‐analysis .Results Fourteen trials were included .Meta‐analysis showed that :the OR (95% CI)of CAD with 1 vascular lesions ,2 vascular lesions ,3 vascular lesions and left main stenosis ,PAD and ARAS were 0 .70(0 .59-0 .82) ,1 .28(1 .10 -1 .48) ,2 .09(1 .69 -2 .59) ,1 .82(1 .40 -2 .36) ,3 .68(2 .21 -6 .10) with statistical signifi‐cance (P<0 .05) .Conclusion CAD with 2 vascular lesions ,3 vascular lesions and left main stenosis ,PAD were connected with ARAS ,CAD with 1 vascular lesions has little relationship with ARAS .
