There is a high degree of information asymmetry in medical services.Public hospitals are characteristic of the nature of multi-layer principal-agent relationships.Asymmetric information can lead to inconsistent value goals between the principal and the agent,giving birth to the government regulation capture as a result.Such capture ranks a fundamental cause for diluted public welfare nature of public hospitals.To offset such capture at public hospitals calls for reconstruction of government regulation system within the framework of public hospital corporate governance at an institution level.It is also necessary to eliminate the information asymmetry and its negative results,bringing public hospitals back on track to public welfare.

ObjectiveTo study the relationship between fasting plasma glucose (FPG) level and the first cerebral infarction event in the population with diabetes.Methods This was a prospective cohort stndy.8 306 diabetic subjects who determined FPG ≥ 7.0 mmol/L or treated with insulin or hypoglycemic drugs and FPG <7.0 mmool/L as the observation population and were followed-up for (48.01 ± 3.14) months.During the course,cerebral infarction events were determined every 6 months.Results( 1 ) By the end of following-up,with the increasing levels of the baseline FPG,the total cholesterol (TC),triglyceride (TG) levels were gradually increased in the diabetic population,the differences were significant [ TC:( 4.93 ± 1.15,5.10 ± 1.20,5.15 ± 1.28,5.33 ± 1.35 ) mmol/L,TG:( 1.70 ± 1.26,1.83 ± 1.29,2.18 ± 1.76,2.41 ± 2.08 ) mmol/L,P<0.05 ] ; the plasma low density lipoprotein-cholesterol (LDL-C),systolic blood pressure ( SBP),diastolic blood pressure ( DBP),and body mass index (BMI) levels were also increased significantly ( P<0.05 ).(2) The ineidence of cerebral infarction event in the group of patients with 7.0 mnol/L ≤ FPG < 9.0 mmol/L was the lowest,the differences were significant ( 2.1%,P <0.01 ).Compared with the group of 7.0 mmol/L≤ FPG<9.0 mmol/L,after adjusting for age,sex,BMI,SBP,DBP,TC,TG,low density lipoprotein-cholesterol,high density lipoprotein-cholesterol,smoking,diabetic duration and treatment,the relative risk for cerebral infarction events were 1.85 (95% CI 1.09-3.15,P<0.05) and 1.54 (95%CI 1.16-2.05,P < 0.01 ) for those groups with 6.1 mmol/L ≤ FPG < 7.0 mmol/L and FPG ≥ 9.0 mmol/L respectively.ConclusionThe risk of new in cidence of cerebral infarction events seems to be the lowest in the group of diabetic patients whose FPGs are wihin 7.0-9.0 mmol/L range.

Objective To investigate the relationship between waist circumference and new-onset non-alcoholic fatty liver disease in non-obese patients with diabetes mellitus. Methods A total of 1 950 patients with diabetes mellitus, who determined fasting plasma glucose(FPG)≥7.0 mmol/L or who were using hypoglycemic drugs and FPG<7.0 mmol/L,and body mass index (BMI)< 25 kg/m2, was selected in this study using prospective cohort method. Patients were divided into five groups according to the baseline data of waist circumference, including waist circumference<78 cm (A group, n=387), 78 cm
