Abstract
Background & objectives: Diabetes mellitus is a common metabolic disorder that has negative effect on physical function, psychological condition, interpersonal, family and social relationship and in general, on psychological well being. The aim of this study was to investigate of psychological profile in diabetic patients and it's relatioship with social support. Methods: In this descriptive-correlational study, 120 diabetic patients have been selected among of those that systematically refered to Diabetes Clinic of Emam Khomeini Hospital in order to follow their therapeutic process in Ardabil . Data gathering was accomplished by two tests: SCL-90-R and Social Support Scale. Finally data were analyzed by Pearson correlation coefficient and T-test on SPSS-17 software and p-value less than 0.05 considered as significant. Results: Results showed that 70% of diabetic patients had problems in somatic complaint and obsession, 62.5% in sensitivity, 72.5% in depression, 62.5% in anxiety, 55% in hostility, 67.5% in paranoid thoughts, 27.5% in phobia and 37.5% in psychosis. Correlations between social support with somatic complaint, obsession, sensitivity, depression, anxiety, hostility and paranoid thoughts were negatively significant. Family support associated significantly with all of the psychological variables but friend Support had no significant correlation with them. Conclusion: The range of psychological problems experienced by diabetic patients is more extensive and these problems have significant relationship with social support. Thus, attention to different dimensions of psychological health is necessary and social support-based interventions can be more effective.

Abstract
Background & Objectives: Diabetes mellitus is a metabolic disease characterized by hyperglycemia together with biochemical alterations of lipid profile, insulin resistance and inflammation . Considering the high prevalence of hypertension, dyslipidemia and inflammation in type 2 diabetic patients, the aim of the present study was to investigate the effects of inulin on lipid profile, inflammation and blood pressure in women with type 2 diabetes. Methods: In this controlled, randomized clinical trial, 49 women with type 2 diabetes (fiber intake<30 g/d, BMI=25-35 kg/m2) were assigned to one of two groups. Experimental group (n=24) received 10 g/d inulin and control group (n=25) received 10 g/d maltodextrin for 8 weeks. Dietary intakes, anthropometric measurements, blood pressure, serum lipids and hs-CRP concentrations were measured at the baseline and at the end of the study. Data were analyzed using SPSS software (verision11.5). Paired, independent t-tests and ANCOVA were used to compare quantitative variables. Results: At the end of study, there was a significant decrease in systolic blood pressure (from 135.7 ± 16.2 to 125.9 ± 7.9 mmHg), total cholesterol ( from 192.5 ± 42.8 to 171.0 ± 39.7 mg/dl), triglyceride ( from 223.3 ± 84.2 to 169.9 ± 65.6 mg/dl) and hs-CRP ( from 7.9 ± 3.0 to 5.3 ± 3.0 mg/l) in inulin group compared with the maltodextrin group (p > 0.04 ). Changes in diastolic blood pressures, LDL-c and HDL-c were not significant in inulin group compared with the maltodextrin group. A significant decrease in systolic, diastolic blood pressures, total cholesterol, triglyceride, LDL-c, hs-CRP and significant increase in HDL-c were observed in inulin group compared to baseline. Conclusions: Inulin supplementation may improve lipid profile, hs-CRP and blood pressure in women with type 2 diabetes.

Abstract
Background & objectives : CXCL5, also known as epithelial cell-derived neutrophil-activating peptide (ENA-78), is a chemokine that has a role in some diseases. CXCL5 blocks insulin signaling by activating the Jak2/STAT5/SOCS2 pathway. It is reported the association between -156G>C (rs352046) polymorphism in the promoter region and diabetes. The aim of this study was to examine whether there is an association between this polymorphism and diabetes mellitus in Ardabil province population. Methods : A total of 100 patients affected diabetes were recruited from Ardabil province population 100 healthy control subjects also were recruited from the same area. The region containing the CXCL5 - 156G>C polymorphism was genotyped by PCR amplification and restriction fragment length polymorphism analysis, and allele frequency data were analyzed using Fisher test. Results : The results show a higher frequency of carrying both the G/G and G/C genotype in patients with diabetes compared with healthy controls (p-value=0.01 and 0.006, respectively). In addition, the frequency of allele C was significantly increased (p-value = 0.028) in patients with diabetes (25.5%) compared with controls (12%). Conclusions : Our findings suggest a role of CXCL5 in the pathogenesis of diabetes. Also, replications in other populations with larger sample sizes are required to confirm these findings.

Abstract
Background & Objectives: Diabetes is a chronic disease characterized by derangement in protein, fat and carbohydrate metabolism. Most of hypoglycemic agent used in medicine for diabetes treatment are reported to have side effects for long run. On the other hand, increase in oxidative stress is effective in the genesis of diabetes. Therefore, the purpose of this study was to assess the effect of alcoholic extract of Euphorbia cyparissias on serum glucose and antioxidant enzymes level in diabetic male rats. Methods : In this study, 40 adult male Wistar rats weighting 250±20 grams divided into four groups randomly: control, diabetic animals, treatment 1 and treatment 2 which received 500 and 250 mg/kg of E.cyparissias extract for 21 days by gastric gavage, respectively. At the end of the treatment, level of antioxidant enzymes including TAC, MDA, SOD and GPX and also blood glucose were determined in animal's serum. Results : The blood glucose levels were significantly lowered in the group of treatment 1 compared to diabetic group (p<0.05). Results showed that MDA level of serum was increased significantly in diabetic group in comparison with control group (p<0.05). Furthermore, the TAC, SOD and GPX level were increased significantly in the group of treatment 1 compared to diabetic group (p<0.05). Conclusion : This study showed that oral administration of E.cyparissias extract has antidiabetic and antioxidant activity in streptozotocin induced diabetic rats.

Abstract
Background & Objectives: Chronic renal failure (CRF), also known as chronic kidney disease, caused by devastated nephron mass of the kidney results in uremia. Hypertension, diabetes mellitus and glomerulonephritis are common etiologic factors of CRF. This condition causes miscellaneous oral manifestations especially in diabetic patients. The aim of this study was to comparison oral manifestations of diabetic and non-diabetic uremic patients undergoing hemodialysis. Methods: A total of 95 patients who undergoing hemodialysis in Razi hospital in Rasht city participated in this descriptive analytical study. Patients were divided into two diabetic and non- diabetic groups. Oral cavity examinations were done by latex gloves and single use mirror. Objective and subjective oral manifestations such as xerostomia, bad taste, mucosal pain, uremic odor, coating tongue, petechial, purpura, pale oral mucosa, ulcer, dental erosion and candida infection were recorded in questionnaire. After gathering of information, the data were analyzed by SPSS 15 software using t-test and chi square statistical test. Results: About 60% of patients (57 person) were men and 40 % (38 person) were women. The mean age of patients was 48 years (range of 20 -76 years). Common subjective oral manifestation in both groups was xerostomia and most common objective oral manifestations were pale oral mucosa, uremic odor and coating tongue respectively. The DMFT index in diabetic group was significantly higher (17.3±7.63) than non-diabetic patients (12.4±8.26). There was no significant statistical correlation between the time of dialysis, number of dialysis appointment during the week and objective and subjective oral manifestations in two groups. Conclusion: Although, the present study has shown an increase in oral manifestations in diabetic patients undergoing hemodialysis relative to non-diabetic group, but this increase was not statistically significant. On the other hand results of our study have indicated significantly higher DMFT in diabetic group in comparison with the non-diabetic group. So patients with diabetes mellitus undergoing hemodialysis need to more oral and dental health care.

Abstract
Background & objectives: Type 2 diabetes mellitus results in vascular dysfunction and reduction of nitric oxide (NO) level. In this study the effect of electromagnetic field (EMF) on NO level, an effective factor in increasing blood flow, and on ankle brachial index (ABI) as a n index of lower extremity blood flow in type 2 diabetic patients, have been investigated. Methods: This study was a randomized controlled clinical trial carried out in Imam Khomeini hospital of Ardabil and Mehr physiotherapy center in 2013. Thirty diabetic patients after initial pilot study participated in this experiment based on inclusion and exclusion criteria. Then, they were randomly assigned into two equal groups, electromagnetic therapy and control. The baseline levels of ABI and NO of both groups were measured. Patients in electromagnetic group were exposed to 10 Hz EMF radiation (with intensity of 8 mT) together with scanning lower limbs (three sessions per week, and 40 minutes per session for 8 weeks). The control group did not receive any treatment. After eight weeks, the amount of ABI and NO level were recorded. For statistical analysis paired t-test and independent t-test were used in SPSS 19 software. Results: Statistical analysis showed significant differences between pre (1.009±0.02) and post (1.052±0.02) measurement of ABI of diabetic patient after applying magnetic field ( P = 0.013). However, there was no significant difference between p and after measurement of ABI and NO level in controlgroup and also NO level in magnet groups ( P> 0.05). Difference between pre and post therapy of ABI in electromagnetic group (0.05±0.01) showed significant increase compared with control group (0.004±0.003) ( P = 0.001). Conclusion: Increase in ABI after 8 weeks electromagnetic therapy could be considered as an accretion index in blood flow in lower extremity.

Abstract
Background & objectives: Successful implementation of diabetes care can reduce acute and chronic complications of diabetes. This study was conducted to evaluate the quality of care according to a care scoring system among people with type 2 diabetes referring to the diabetes clinic in Ardabil.
Methods: This cross sectional study was conducted in 2014 and a total of 300 people with type 2 diabetes in age range of 20-70 years old were included via convenience sampling. Data were collected by an interviewer using a structured questionnaire and checklist. Each patient was classified according to a quality of care scoring system into 3 categories: ≤10, 15-20, >20. Statistical analysis performed by SPSS v.20 software and descriptive analysis used to display data as frequency tables and graphs. Analytical tests such as ANOVA, Kruskal-Wallis, Chi squared, and fisher exact test were also used to analyze the data.
Results: The mean age of patients was 54.13 ± 9.13 and the majority of them were women (72.3%). The mean of BMI and HbA1c was 29.58 ± 4.77 and 8.93± 2.13, respectively. The mean of FBS was 191.18 ± 84.23 and the average length of disease was 7.74±5.89 years. The mean of quality of care score among participants was 23.20±9.99. About one-third of patients (29.7%) had a quality care score ≤10, half of them (51%) had a score between 15-20, and only 19.35% had a score >20. There was an association between HbA1c, FBS, diastolic blood pressure, cholesterol and LDL with a quality of care score which was statistically significant (p<0.05).
Conclusion: In this study there was a gap between the current quality of care of patients and recommended standards. Therefore in order to minimize the current barriers and problems it is recommended to implement an effective interventional program. In addition, using a quality care scoring system is a rapid, easy and valid method for evaluating diabetes quality of care.

Abstract
Background & objectives: Type II diabetes is a metabolic disorder accompanied with insulin resistance of the whole body cells and is considered be the fifth cause of death in the world. Adaptation to altitude can lead to tolerance to many diseases. Therefore, the aim of this study was to determine the effect of simulated intermittent altitude on the metabolic and hematologic parameters and liver function in streptozotocin induced diabetic rats.
Methods: In the current experimental study, twenty four male Wistar rats weighing 220±20 gr were randomly divided into three groups; normal control group (NC, n=8), diabetic control group (D, n=8) received fat diet for 2 weeks then were injected with streptozotocin (37 mg/kg) and diabetic+hypoxia group (D+H, n=8) including diabetic rat exposed to chronic intermittent hypoxia (PiO2≈106 mm Hg, simulated altitude≈3400 m, 14% oxygen for 8 weeks). Diabetic, hematologic and lipid parameters as well as ALT and AST activities were measured in peripheral blood.
Results: Our findings showed that intermittent hypoxia significantly decreased serum total cholesterol, LDL ,VLDL and triglyceride in D+H group compared to D group (p<0.05). Serum levels of fasting blood glucose and homeostatic model assessment-insulin resistance )HOMA-IR( index and ALT were decreased in D+H group vs. D group )p<0.05). Also, hemoglubin and hematocrite level increased in D+H group in comparison to D group )p<0.05). No significant difference was detected in red blood cell count in D+H vs. D group.
Conclusion: Based on resultant data, it seems that intermittent exposure to hypoxia (simulated to chronic and intermittent lodgement in altitude) can be used to control of type 2 diabetes by increasing hemoglobin, decreasing insulin resistance and improving liver function as well as lipid parameters.

Abstract
Background & objectives: Type 2 diabetes is a metabolic disorder considered as one of the most common chronic diseases in many countries, including Iran. One of the reducing factors in insulin sensitivity is increased serum levels of inflammatory factors like hsCRP and TNF-α. On the other hand, in recent years, Cuminum Cyminum is known as one of the potent herbs in the treatment of diabetes type 2 in animal studies. The aim of this study was to evaluate the effect of two doses of 50 and 100 mg of Cuminum Cyminum extract on glycemic indices and indicators of inflammation in human subjects with type 2 diabetes mellitus.
Methods: This study is a double blind randomized clinical trial performed in Urmia city on 2015. Samples were selected based on inclusion criteria and randomly divided into 3 groups: two groups receiving Cuminum Cyminum extract of 50 and 100 mg per day and the control (placebo) group. Before and 8 weeks after intervention, fasting blood sugar, serum insulin and inflammatory profile of hsCRP and TNF-α were measured. Data were analyzed by SPSS and the effect of supplementation was studied.
Results: The mean age of the all participants was 47.33±6.36. Results showed that the mean fasting blood sugar (FBS), glycosylated hemoglobin (HbA1c), and serum insulin reduced significantly in the both groups receiving Cuminum extract of 50 and 100 mg(p<0.01)., but increased in the placebo group. Average hsCRP and TNF-α levels have shown significant reduction at the beginning and end of the study in either group receiving 50 and 100 mg of supplementation (p<0.01).
Conclusion: This study indicates that short-term daily supplementation of Cuminum Cyminum extract at the doses of 50 or 100mg in patients with type 2 diabetes during 8 weeks may act to reduce the serum levels of insulin, blood glucose, glycosylated hemoglobin and hsCRP and TNF-α levels, and also may be fruitful for control of this disease.

Abstract
Background & aim: Nowadays because of difficulty in the supply and injection of insulin and blood sugar reducing drugs and considering the side effects of chemical drugs, researcher’s attention is drawn to using herbal medicines. Liver is one of the organs affected by diabetes in different functional aspects. The purpose of this research was studying the effect of Rosa canina extract on reducing the adverse effects and improving diabetes symptoms related to histophysiology, amount of biochemical serum factors and liver enzymes in male rats.
Methods: 32 male Wistar rats, weighed 200-220 gr, were divided into 4 groups. Diabetes was induced by intraperitoneal injection of STZ (60mg/kg). The period of experiments was 4 weeks. At the end of experiments, the rats were sacrificed and their serums were collected for measurement of liver enzymes. Also, histological sampling of liver was done. Statistical analysis was performed using analysis of variance (one-way ANOVA).
Results: The results of this study showed that treatment with ethanol extract of Rosa canina led to significant reduction of liver enzymes in the Rosa extract-treated groups in comparison with the diabetic group, indicating the protective effect of alcoholic extract of Rosa canina on liver tissue against diabetes-induced damages. In liver histopathology, a distinct fat change in the lobular center areas was created in the diabetic group. Pathological changes were not significant in the liver of the Rosa extract-treated groups; liver in this group was relatively healthier than in diabetic group.
Conclusions: Rosa extract improved this organ's function in STZ-induced diabetic rats by reducing serum biomarkers of liver pathology and reducing histological damages.

Abstract
Background & objectives: Diabetes mellitus is the sixth leading cause of death in individuals older than 25 years, and accounts for %18 of all deaths. The aim of this study was to investigate the TCD findings in diabetic patients with a history of less and more than 5 years.
Methods: In this descriptive, analytic study, all diabetic patients were divided into two groups based on the duration of diabetes, less and more than 5 years after diagnosis. TCD was performed on the patients, and maximum velocity and mean pulsatility index and resistivity index in the right and left Middle Cerebral Arteries (MCAs) and basilar artery were measured. The checklist was completed for all patients, and all data were analyzed by SPSS (v16) statistical software.
Results: Sixty four percent of the patients with duration less than 5 years (average age of 55.16 years) and 36 percent of those with duration more than 5 years (average age of 59.37 years) were men. There was no statistically significant difference between disease duration and Body Mass Index (BMI), but with an increase in duration of disease, HbA1C of patients was increased. There was no significant difference between the velocity of right, left and basilar arteries and diabetes duration. Also, there was a significant difference between diabetes duration and pulse index of right MCA and basilar. There was no significant difference between age, BMI and HbA1C and pulse and resistivity indexes among patients.
Conclusion: In this study abnormal pulse and resistance indexes in patients with duration more than 5 years was more than patients with less than 5, this may indicate the effect of diabetes duration on the vascular wall.

Abstract
Background & objectives: Diabetes mellitus belongs to a group of common metabolic disorders characterized by hyperglycemia phenotypes. Diabetes mellitus causes secondary pathophysiological disorders in multiple organs of the body such as nephropathy, which causes many problems for patients and the health care system. In this study, the effect of pentoxifylline, a nonselective phosphodiesterase inhibitor, on reducing urinary protein excretion in diabetic patients was assessed.
Methods: In this clinical trial, 72 diabetic patients with proteinuria who were admitted to the endocrine and nephrology clinic were selected and divided into two groups. Checklists, including demographic data, etc. were completed. In group (A), Angiotensin-converting enzyme inhibitors (ACEI) or Angiotensin II receptor blockers (ARBs) were prescribed to reduce proteinuria, and in another group (B), in addition to ACEI or ARB drugs, pentoxifylline was prescribed. In the end, the results in both groups were compared in terms of further reduction of proteinuria.
Results: Most of the studied patients were male. There was a significant correlation between proteinuria (mean urinary protein excretion in 24 hours) and the effect of pentoxifylline on reducing proteinuria in patients with type II diabetes. Also, there was not a significant difference in systolic and diastolic blood pressure changes and HbA1c between the two groups at the beginning and end of the study.
Conclusion: Pentoxifylline, independent of lowering blood pressure or reducing the improvement of metabolic control, can significantly decrease proteinuria and protein excretion

Abstract
Background & objectives: Diabetes mellitus cause cognitive defects. Royal Jelly has been claimed to improve the neurological damage caused by diabetes. In this study, the effect of oral administration of royal jelly on memory and passive avoidance learning was studied in diabetic male rats.
Methods: This experimental study was conducted in Qazvin University of Medical Sciences on 48 male Wistar rats. The animals were divided into control, diabetic without treatment, diabetic recipient of glibenclamide (600 μg/kg) and three diabetic groups treated with 50, 100 and 200 mg/kg royal jelly (n=8). Diabetes was induced in the animals by intraperitoneal injection of streptozotocin (60mg/kg/ip). Treatment in the groups performed by gavage from the onset of hyperglycemia for 30 days. At the end of the test, the passive avoidance learning and memory and blood glucose were measured. Data were analyzed by by SPSS software using ANOVA and post-hoc LSD tests, and p<0.05 was considered significant.
Results: Diabetes reduced the latency time of dark room entering. Royal jelly treatment delayed the entrance to the dark room significantly at 24 h, 48 h and 2 weeks after the shock, especially at doses of 100 (p<0.05) and 200 mg/kg (p<0.01) compared to untreated diabetic animals.
Conclusion: According to the results, diabetes causes memory impairment, and royal jelly administration can reduce the memory impairment due to diabetes.

Abstract
Background & objectives: Considering the prevalence of diabetes and importance of its prevention, control and treatment, using low-calorie natural sweetener is necessary. Hepatoprotective and antidiabetic properties of the aqueous extract of Stevia. rebaudiana were assessed in the present study.
Methods: In this study, 35 mature male mice were divided into 5 groups. Diabetes was induced by administration of 60 mg/kg of streptozotocin intraperitoneally. The negative control group received normal saline and treatment groups received glibenclamide with 0.5 mg/kg and 200 and 400 μg/kg of aqueous extract of S. rebaudiana through gavage for 15 days, respectively. Also, one group was considered as positive control (as non-treated diabetic). On the last day, the blood glucose levels of samples were measured. After periodic acid Schiff (PAS) staining, 5μm of sections were used for stereological analysis.
Results: The blood glucose level was decreased (p<0.05) significantly in aqueous extract-treated groups compared to the untreated diabetic mice. The weight and volume of kidneys, cortex, medulla, proximal and distal tubules, collecting ducts, loop of henle, interstitial tissues, vessels and length of renal tubules decreased significantly (p<0.05) after treatment with aqueous extract of S. rebaudiana (p<0.05). The number and volume of glomeruli restored toward normal levels with high doses of S. rebaudiana.
Conclusion: According to the obtained results, aqueous extract of S. rebaudiana (sweet fraction) can regulate the blood glucose levels and inhibit diabetes-induced renal damages. It seems that S. rebaudiana can be used as an antidiabetic and nephroprotective supplement.

Abstract
Background & objectives: Irisin is a novel myokine that encoded by FNDC5 gene and effects on obesity, metabolism and glucose homeostasis through browning of white adipose tissue and thermogenesis. The main purpose of this study was to investigate the changes of FNDC5 gene expression and Irisin protein level of visceral fat tissue after eight weeks of resistance training in type 2 diabetic rats.
Methods: Eighteen male Wistar rats (8 week old) were used for this study. Diabetes was induced using nicotinamide and streptozotocin . Five days after inducing diabetes, rats with fasting blood glucose levels between 127-600 mg / dl were selected as diabetic subjects. Rats were homogenized according to the body weight and assigned into two groups including control-diabetes (n=9) and resistance training-diabetes (n=9). Training group exercised resistance training for eight weeks (5 days a week). The resistance training protocol consisted of climbing a one-meter- high ladder, with a weight attached to a tail sleeve. Quantitative Real time RT-PCR and ELISA Kit were used for assessment of expression level of FNDC5 gene and Irisin protein, respectively. Data were analyzed using independent t- test at p≤0.05.
Results: Resistance training significantly increased the expression level of FNDC5 gene and Irisin protein in visceral adipose tissue in type 2 diabetic rats.
Conclusion: It seems that FNDC5 gene and Irisin protein have an important role in metabolic diseases and can be affected by resistance training. Perhaps the changes in the levels of these metabolic indicators is a potential new target for the treatment of metabolic disorders, such as T2DM (type 2 diabetes).

Abstract
Background & objectives: Type 2 diabetes mellitus (DM) is a metabolic disorder that is common throughout the world. Meta-analysis is a statistical technique in which the results of two or more independent studies, with similar objectives, are mathematically combined in order to improve the reliability of the results. The aim of this study was to compare the efficacy of metformin and linagliptin in patients with type 2 diabetes.
Methods: To identify relevant studies, PubMed, ISI Web of Science, Embase, Cochran library, Scopus and Ovid databases were searched from January 2000 to August 2016. Mean difference (MD) with 95% confidence interval (CI) for efficacy were calculated and pooled analysis was performed using Stata V.12 and RevMan V.5.3 software.
Results: Four studies recruiting1260 patients with DM (682 patients in group linagliptin and 578 patients in metformin group) were included in this study. The MD of HbA1C outcome of 0.5 mg linagliptin was effective (0. 7295, % CI = 0. 69 - 0. 75). The MD of fasting blood sugar (FBS) test revealed that linagliptin was effective at 0.5mg (MD = 36.79, 95% CI = 35.20 - 38.38) and 5 mg (MD = 12.65, 95% CI = 2.68 to 22.63) doses.
Conclusion: Our results suggest that some doses of linagliptin versus metformin may be an effective treatment for DM2. However, the number of studies was limited, and further research is needed.
