Objective To investigate the variance of cost-effectiveness when treat acute myocardial infaretion of different severe extents with different pattern.Methods Acute myocardial infarction patients were selected from emergency eommand center of Guangzhou from October 2003 to December 2005.These patients wew assigned by the center to First-Class Hospitals at Grade 3 and First-class Hospital at Grade 2,and were followed up after 6 months after post-discharge.Cost in hospital and mortality in hospital were registered.The health of all patients were quantificated using SF-36.According to the assigned hospitals,the patients were divided into single infarction group and complex infarction group.Cost in hospital,mortality in hospital,short-term quality of life were compared between the them.Results Compared with and First-Class Hospital at Grade 2 (101 cases),the single infarction patients in First-Class Hospitals at Grade 3 had higber costs in hospital (P=0.016),better society function,affection role,mental health and health status (P

Objective To investigate glycemic control,changes of inflammatory factors and their clinical significance in severe sepsis patients.Methods One hundred and three severe sepsis patients with abnormal hyperglycemia were randomly divided into the two groups and receive intensive insulin therapy (IIT) and conventional insulin therapy (CIT) respectively.According to glycosylated hemoglobin level,the two groups were further divided into stress hyperglycaemia and diabetes mellitus subgroups.The mortality and incidence of hypoglycemia were compared between the groups and subgroups.Enzyme linked immunosorbent assay was used to detect TNF-α,IL-6 levels before treatment,3 and 7 days after treatment.Results In IIT group,the mortality in diabetes mellitus subgroup was significantly higher than that in stress hyperglycaemia subgroup (66.7％ vs.30.8％,P ＜ 0.05),while the mortality in stress hyperglycaemia subgroup significantly higher than that in diabetes mellitus subgroup (54.1％ vs.25.0％,P ＜ 0.05) in CIT group.Multivariate Logistic regression analysis revealed IIT increased the risk for death in diabetes mellitus subgroup (OR =1.221,95％ CI:1.075-1.434),while decreased the risk for death in stress hyperglycaemia subgroup (OR =0.872,95％ CI:0.714-0.975).The incidence of hypoglycemia was significantly higher in IIT group than that in CIT group (13.7％ vs.1.9％,P ＜0.05).Before treatment,the levels of TNF-α,IL-6 in stress hyperglycaemia patients were significantly higher than those in diabetes mellitus patients.After 7 day treatment,The levels of TNF-α,IL-6 decreased significantly in stress hyperglycaemia patients (P ＜ 0.01),and decreased more significantly in IIT group than that in CIT group.Conclusion Severe sepsis patients with stress hyperglycaemia can attain better glycemia control and inhibition of inflammatory factors,and clinical benefit from IIT.
