Objective To explore the effect of health education on the blood glucose controlling target in patients with type 2 diabetes. Methods 598 cases of patients with type 2 diabetes were randomly divided into the control group (given conventional treat- ment and medication guide) and the intervention group (besides the above-mentioned treatment, also given diabetes health management program including the systemic health education and promotion, and with stress on behavioral, psychological, dietary intervention) and observed for 7 months. Results After 7 months intervention, there were differences in the levels of glycosylated hemoglobin, fasting plasma glucose and 2h postprandial blood glucose between two groups (P

Objective To evaluate right ventricular (RV)systolic function in type-2 diabetes mellitus (T2DM)patients.Methods Fifty T2DM patients and fifty normal controls were included in the study and underwent echocardiographic examinations.The following parameters were measured:1 ) Right heart dimensions,pulmonary artery (PA)diameter,pulmonary acceleration time (AT)and PA systolic pressure (PASP);2)RV systolic function:RV fractional area change (RVFAC),tissue Doppler-derived tricuspid lateral annular systolic velocity (S'),tricuspid annular plane systolic excursion (TAPSE),longitudinal strain of six RV segments by 2-dimensional speckle tracking imaging (2D-STI);3 )RV diastolic function:E,A ratio of the tricuspid inflow spectrum (E/A),E,E'(peak early diastolic velocity of the tricuspid annulus) ratio (E/E');4)RV Tei index.Results Statistic analysis showed that T2DM patients had thicker RV walls,wider PAs and shorter AT than the control group (P =0.000,0.001 and 0.000),while their right heart chamber sizes and PASP remained unchanged.Among systolic parameters,absolute values of RV longitudinal strain at the lateral wall-mid (lat-m),septum-mid (sep-m)and septum-basal (sep-b)segments were significantly lower in the diabetic group than the control group (P =0.001 ,0.000 and 0.005),whereas strain of the other three RV segments and RVFAC,TAPSE.S'were not significantly different.Moreover, E/A,E/E'and Tei index were all significantly different between the two groups (P = 0.000,0.000 and 0.006),indicating declined diastolic and general function of RV in the T2DM group.Conclusions RV myocardial strain by 2D-STI is more sensitive in detecting RV systolic dysfunction than TAPSE,S' and RVFAC.Among the six segments of RV walls,lat-m,sep-m and sep-b are better locations for 2D-STI than the other three.

Objective:To explore teaching methods to improve the teaching effect in view of many difficulties in learning medical statistics for clinical medical students.Methods:Taking the clinical medical students of the same grade as the research objects, the students were randomly divided into two groups by cluster sampling in class, i.e. control group and experimental group. The traditional teaching methods and the scenario-based interactive learning software teaching methods were used respectively. The scores of medical statistics courses examinations and the statistical errors in responding to projects of extracurricular research activities were compared between the two groups. SPSS 19.0 was performed for statistical analysis.Results:The results of subject achievements of the students in the experimental group (74.08±11.19) were higher than those in the control group (63.82±10.10) ( t=3.926, P<0.001), especially the comprehensive capabilities of the innovative analysis questions and the multiple-choice questions. The statistical errors of the students in the experimental group was less than those in the control group. There were significant differences between the two groups in the estimation of sample size ( χ2=4.189, P=0.041), statistical design ( χ2=5.558, P=0.018) and data analysis ( χ2=3.971, P=0.046). Conclusion:The results suggest that scenario-based interactive learning software is helpful to improve teaching efficiency, and enhance students' ability to analyze and solve practical problems by using medical statistics knowledge.

Objective　To investigate the correlation between red cell distribution width to platelet ratio and short-term prognosis in acute ischemic stroke.Methods　The patients with ischemic stroke admitted in the First Affiliated Hospital of Zhengzhou University during the initial 24 hours after the onset of disease between 2015-2017 were recruited prospectively.Red cell distribution width (RDW),platelet and clinical characteristics were recorded.Functional outcome at 90 days after ischemic stroke was evaluated by the modified Rankin Scale (mRS).Results　Totally 1106 patients were included.Patients with poor functional outcome were older (P＜0.001=and had more frequent histories of hypertension (P=0.015),diabetes (P=0.001),atrial fibrillation (P＜0.001=,coronary heart disease (P=0.041),stroke (P＜0.001=and higher National Institutes of Health Stroke Scale (NIHSS)(P＜0.001=,white blood cell count (P＜0.001=,RDW (P＜0.001=and RDW to platelet ratio (RPR) (P=0.034).Higher RPR levels were associated with poor functional outcome at 90 days after ischemic stroke［(odds ratio,OR) 1.09,(confidence interval,CI) 1.03~1.16，P=0.005］. Conclusion　Higher RPR levels were associated with poor short-term outcome after acute ischemic stroke.
