Objective To investigate the intervention of trans-theoretical model on the risk factors in the patients with prediabetes.Methods One hundred and twenty-two patients with pre-diabetes in a tertiary hospital of Zhengzhou City were selected and randomly assigned to control group and intervention group.The control group received the routine diabetic health education,while in addition to the routine health education,the intervention group was assisted by TTM interventional measures.The blood glucose,body mass index(BMI) and negative emotion were compared between the two groups.Results The blood glucose and BMI after intervention in the two groups were decreased,moreover the decrease level of fasting blood glucose and BMI in the intervention group was higher than that in the control group,and the difference was statistically significant(t=4.963、2.061,P＜0.05).The anxiety and depression emotion scores after intervention in the intervention group were [(3.47 ±1.07) and (0.30 ± 0.46)],before intervention were (7.74 ± 4.00) and(7.25 ± 4.50),The difference was statistically significant(P＜0.05),Moreover the anxiety and depression emotion scores after intervention in the intervention group were lower tghan those in the control group with statistical difference(t=3.300、2.054,P＜0.05).Conclusion The intervention measures based on TTM has significant advantage for controlling the risk factors of pre-diabetes and preventing diabetes than the conventional health education.

Objective To explore the molecular mechanism of blood_stasis syndrome (BSS) by studying the changes of gene expression of endothelin (ET) and constit utive nitric oxide synthase (cNOS) in vascular endothelial cells (VEC) cultured w ith BSS rabbit serum. Methods ET_1 mRNA expression and cNOS mRNA expression were analyzed by semi_quantitative reverse transcription and polymerase chain re action method. Results ET_1 mRNA expression level was increased and cNOS mRN A expression level was decreased in VEC cultured with BSS rabbit serum (Group A) as compared with VEC cultured with normal rabbit serum (Group B) or without rab bit serum (Group C) (P

Objective To investigate the knowledge and influencing factors of diabetes in middle-aged and elderly patients with prediabetes, and to provide evidence for public education in those patients. Methods According to convenient sampling, the questionnaire survey was conducted in 234 middle-aged and elderly patients with prediabetes who had a physical examination in a class Ⅲ grade A hospital in Zhengzhou from July to December 2014.Results There were significant differences in knowledge points of diabetes, diet dimension and total points in middle-aged patients compared with elderly patients (P<0.05), however, there was no significant difference in risk factors, treatment and exercise knowledge dimension (P>0.05). The multivariable linear regression analysis showed that the main factors for knowledge were marital status and educational level in middle-aged participants, and educational level and family history of diabetes in elderly participants.Conclusions The knowledge of diabetes should be strengthened in middle-aged patients with prediabetes who have low education level and no spouse, and in elderly patients with low education level and no family history of diabetes.
