Abstract
Background: One of the important indicators of diabetes treatment and control is enhancement of quality of life in patients with diabetes. Therefore, in recent years, quality of life in these patients regarded by therapists and researchers and increased studies in this field. The aim of this study was collection and integration of these studies results to investigate the effect size of sport and psychological interventions on quality of life in patients with type 2 diabetes by meta-analysis method. Methods: For this purpose, 25 acceptable studies (15 psychological interventions, 10 sport interventions) in terms of methodology (hypothesis, research method, statistic population, volume of sample, sampling method, instrument measure & statistic analysis method) selected, and meta-analysis performed on them. Research instrument was checklist of meta-analysis. Results: The study findings showed that the rate of effect size of psychological interventions on quality of life in patients with type 2 diabetes was d=0.95 (p<0.00001) and the effect size of sport interventions on quality of life in this patients was d=2.2(p<0.00001). According to Cohen’s chart both effect sizes of sport and psychological interventions were high. Conclusion: psychological and sport interventions can be effective on improvement of quality of life in patient with 2 diabetes.

Abstract
Background:Diabetes mellitus is regarded as a major health problem due to its complications that these,nonetheless could be prevented or delayed with changes and modifications in the patients’ behavior and dietby understanding their beliefs..The objective of this study was to explore the utility of the Theory of PlannedBehavior (TPB)and complications of diabetes perceived risk to find modifiable diabetes-related believes inorder to make behavior changes feasible.
Methods: The presentdescriptive-analytical cross sectional study was conducted in Semirom Diabetes Clinicbased on the TPBand complications of diabetes perceived risk, using a self-administered questionnaire. Atotal of 154 diabetic patients without complications of diabetes were participated in the study. Measured variables were patients’ attitude, subjective norm, perceived behavioral control, complications of diabetesperceived risk, intention to eat a healthful diet and nutritional style. Structural equation modeling was used toanalyze data.
Results:The results revealed that the TPBand complications of diabetes perceived risk fitted the data
acceptably well among the Type 2 diabetes and within dietary behavior. Perceived behavioral control,
subjective norm, complications of diabetes perceived risk and intention to eat a healthy diet were related tohealthy diet behavior. No relation was found between attitude and intention to eat a healthy diet.
Conclusion:The TPB and complications of diabetes perceived risk is a useful theory in determining
intentions of diabetic patients’ and their adherence to healthy diets. TPB and complications of diabetes perceived risk forms a framework for promoting dietary practice among Type 2 diabetic patien

Abstract
Introduction: Diabetes is one of the most common disorders of the endocrine glands, the main characteristic of which is an increase in the concentration of glucose in the serum of patients. Herbal medicines are widely accepted by people due to less side effects. The purpose of this study is to investigate the protective effect of the silybum marianum, melissa officinalis, vaccinium arctostaphylos, trigonella foenum, urtica dioica and citrullus colocynthis extracts mixtures in the PC12 cell model in a high glucose environment.
Methods and Methods: After 24, 48, and 72 hours of adding different concentrations of plant extracts (silybum marianum, melissa officinalis, vaccinium arctostaphylos, trigonella foenum, urtica dioica and citrullus colocynthis) in the normal culture medium of PC12 cells and the medium with high glucose (25 mg/ml, 13/5), cell viability was measured by MTT method.
Results: The results showed that the viability of PC12 cells did not change in 24, 48 and 72 hours after treatment with a mixture of plant extracts. The survival rate of cells in the high dose glucose group was significantly reduced compared to the control group, and the mixture of plant extracts in high doses significantly reduced cell death in these conditions.
Conclusion: Based on the available findings, glucose with a concentration of 25, 13.5 mg/ml caused the death of PC12 cells and the mixture of plant extracts was able to reduce the cell death caused by high glucose in all three times 24, 48 and 72 hours after exposure with nerve cells.
