Erectile dysfunction is common complication of diabetes mellitus. The incidence of diabetes mellitus induced erectile dysfunction (DMED) is 20% - 75%. DMED appears to be due to vascular-neuropathic and corpus cavernosum smooth muscular damage. To control blood glucose, blood pressure and blood lipids is the basis of DMED therapy. In 50% of the patients with DMED, the phosphodiesterase 5 inhibitors is effective, while intracavernous pharmacotherapy is effective for more than 90%. Penile prosthesis implantation continues to be the treatment of choice in case of other therapy failure.

2.Type 2 Diabetes Mellitus and Its Association with the Risk of Pancreatic Carcinogenesis: A Review.
The Korean Journal of Gastroenterology 2016;67(4):168-177
The prevalence of diabetes mellitus (DM) and associated diseases such as cancers are substantially increasing worldwide. About 80% of the patients with pancreatic cancer have glucose metabolism alterations. This suggests an association between type 2 DM and pancreatic cancer risk and progression. There are hypotheses that show metabolic links between the diseases, due to insulin resistance, hyperglycemia, hyperinsulinemia, low grade chronic inflammation, and alteration in the insulin-insulin-like growth factor axis. The use of diabetes medications can influence the extent of carcinogenesis of the pancreas. This study briefly reviews recent literature on investigation of metabolic link of type 2 DM, risk of carcinogenesis of the pancreas and their association, as well as the current understanding of metabolic pathways implicated in metabolism and cellular growth. The main finding of this review, although there are discrepancies, is that according to most research long-term DM does not raise the risk of pancreatic cancer. The longest duration of DM may reflect hypoinsulinemia due to treatment for hyperglycemia, but recent onset diabetes was associated with increased risk for pancreatic cancer due to hyperinsulinemia and hyperglycemia. In conclusion, the review demonstrates that type 2 DM and the duration of diabetes pose a risk for pancreatic carcinogenesis, and that there is biological link between the diseases.

OBJECTIVE:
To explore the relation between diabetes mellitus and clinicopathological factors and the incidence of radiation pneumonitis in patients with non-small cell lung cancer.
METHODS:
The data of 332 patients with non-small cell lung cancer, who were admitted to the Department of Oncology of Third Xiangya Hospital of Central South University between January 2007 and August 2009, were collected retrospectively. The patients were divided into a diabetes mellitus (DM) group (n=45) and a non-diabetes mellitus (NDM) group (n=287). The clinicopathological factors were compared between the two groups. The patients who received radiotherapy were further divided into a diabetes mellitus (DMR) group (n=33) and a non-diabetes mellitus group (NDMR) group(n=287), and the incidence of radiation pneumonitis was compared.
RESULTS:
A total of 45 patients (13.55%)developed diabetes mellitus. There was significant difference in the body-weight, age and hypertension (P<0.05), while no significant difference in the pathologic factors, such as tumor pathological type, degree of differentiation, and classification of malignant tumors (TNM) stage between the two groups(P>0.05). No significant difference in the irradiation area was found between the DM group and the NDM group(P>0.05). The incidence of radiation pneumonitis in the DMR group was 42.42%(14 out of 33), while 21.31%(39 out of 183) in the NDMR group, with significant difference in the incidence of radiation pneumonitis between the DMR group and the NDMR group(P<0.05). The risk value in the DMR group was 2.721 folds (95%CI, 1.253-5.910) that in the NDMR group in patients with non-small cell lung cancer companied with diabetes mellitus.
CONCLUSION
Diabetes mellitus is the risk factor of radiation pneumonitis for patients with nonsmall cell lung cancer who receive radiotherapy.

OBJECTIVES: We evaluated the association between common carotid artery intima-media thickness (CCA-IMT), brachial-ankle pulse wave velocity (baPWV), carotid plaque, and peripheral arterial disease (PAD) as indicators of macroangiopathy and diabetic retinopathy as an indicator of microangiopathy in type 2 diabetic patients. METHODS: We analyzed 605 type 2 diabetic patients registered at a public health center in Korea. Following overnight fasting, venous blood and urine samples were collected and analyzed. The CCA-IMT, levels of carotid plaque, baPWV, and ankle-brachial index (ABI) of the subjects were assessed. We used non-mydriatic fundus photography to diagnose diabetic retinopathy. Multiple logistic regression analyses were used to evaluate the association between macroangiopathy and diabetic retinopathy. CCA-IMT and baPWV were divided into tertiles: CCA-IMT, 0.39 to 0.65 mm, 0.66 to 0.78 mm, and 0.79 to 1.30 mm; baPWV, 9.9 to 15.8 m/s, 15.9 to 18.9 m/s, and 19.0 to 38.0 m/s. RESULTS: The association between baPWV and diabetic retinopathy remained significant after adjustment, with an increasing odds ratio (OR) in the second tertile (OR, 2.41; 95% confidence interval [CI], 1.27 to 4.55) and the third tertile (OR, 4.63; 95% CI, 2.33 to 9.21). No significant differences were observed in carotid plaque, PAD, and each tertile of CCA-IMT. CONCLUSIONS: BaPWV was associated with diabetic retinopathy, while CCA-IMT, carotid plaque, and PAD were not. This study suggests that the association between macroangiopathy and microangiopathy may be attributable to functional processes rather than structural processes within the vascular system.

OBJECTIVEObesity is a major risk factor for type 2 diabetes, many indexes can be used to describes obesity and predict diabetes. This research attempts to identify the best indicator of obesity to screening diabetes in Chinese population.
METHODSA cross-sectional data of 8121 subjects aged 35-60 years were included in this research belongs to the Diabetes Appropriate Technology Intervention Study. Anthropometric indicators including body weight, height, waist circumferences (WC), body fat index (BFI) and visceral fat index (VFI) and blood biochemical indicators after an overnight fast [fasting blood glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triacylglycerol] were measured. BMI (body mass index) and Weight to Height Ratio was calculated.
RESULTSSubjects with obesity had a higher risk of physician diagnosed diabetes (OR=2.50, 95% CI 1.83-3.43), new diagnosed diabetes (OR=4.23, 95% CI 2.91-6.15) and pre-diabetes (OR=1.75, 95% CI 1.31-2.34) compared to those with normal Body mass index (BMI). There was a significant trend of increased risk of all diabetes status with increased waist circumference (WC). The waist-to-height ratio (WHtR) yielded the most significant association with new diagnosed diabetes and physician diagnosed diabetes than other indices.
CONCLUSIONCentral obesity is significantly correlated with diabetes. VFI was most correlated with pre-diabetes while WHtR is an efficient screening index than BMI and WC in Chinese community diabetes screening.

PURPOSE: The severity of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus (T2DM) population compared with that in normal glucose tolerance (NGT) individuals has not yet been quantitatively assessed. We investigated the prevalence and the severity of NAFLD in a T2DM population using controlled attenuation parameter (CAP). MATERIALS AND METHODS: Subjects who underwent testing for biomarkers related to T2DM and CAP using Fibroscan® during a regular health check-up were enrolled. CAP values of 250 dB/m and 300 dB/m were selected as the cutoffs for the presence of NAFLD and for moderate to severe NAFLD, respectively. Biomarkers related to T2DM included fasting glucose/insulin, fasting C-peptide, hemoglobin A1c (HbA1c), glycoalbumin, and homeostasis model assessment of insulin resistance of insulin resistance (HOMA-IR). RESULTS: Among 340 study participants (T2DM, n=66; pre-diabetes, n=202; NGT, n=72), the proportion of subjects with NAFLD increased according to the glucose tolerance status (31.9% in NGT; 47.0% in pre-diabetes; 57.6% in T2DM). The median CAP value was significantly higher in subjects with T2DM (265 dB/m) than in those with pre-diabetes (245 dB/m) or NGT (231 dB/m) (all p<0.05). Logistic regression analysis showed that subjects with moderate to severe NAFLD had a 2.8-fold (odds ratio) higher risk of having T2DM than those without NAFLD (p=0.02; 95% confidence interval, 1.21-6.64), and positive correlations between the CAP value and HOMA-IR (ρ=0.407) or fasting C-peptide (ρ=0.402) were demonstrated. CONCLUSION: Subjects with T2DM had a higher prevalence of severe NAFLD than those with NGT. Increased hepatic steatosis was significantly associated with the presence of T2DM, and insulin resistance induced by hepatic fat may be an important mechanistic connection.

OBJECTIVETo determine the prevalence and clinical phenotype of metabolic syndrome among overweight and obese schoolchildren in Beijing, and to compare the rates of diagnosis made according to the criteria of the National Cholesterol Education Program (NCEP) of the United States and International Diabetes Federation (IDF).
METHODSBased on Beijing Child and Adolescent Metabolic Syndrome (BCAMS) study with body mass index (BMI), waist circumference (WC) and blood pressure measured, the overweight and obese children were screened among nearly 20 000 children 6-18 years of age in Beijing by Chinese BMI cutoffs for schoolchildren (7-18 years) and the US 2000 CDC Growth Charts--the 85th and 95th percentile (6 years) and were enrolled as the study population. Simultaneously a group of children with normal BMI were selected as the control group and based on the international method of age grouping, each of the above groups was divided further into 4 sub-groups in terms of age: 6-9, 10-12, 13-15 and 16-18 years old, respectively. Fasting plasma glucose (FPG) and insulin (FINS), serum high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) were examined. HOMA-IR index was calculated for estimating individual insulin resistance. A child who met any three or more of the following five criteria, according to NCEP definition, was diagnosed as MS. A diagnosis of MS using IDF definition required abdominal obesity plus any two or more of the other four criteria: (1) abnormal obesity: WC > or = P(90); (2) elevated BPs: SBP/DBP > or = P(90); (3) low HDL-C: HDL-C < 1.03 mmol/L (40 mg/dl); (4) high TG: TG > or = 1.24 mmol/L (110 mg/dl); (5) impaired fasting glucose (IFG): FPG > or = 5.6 mmol/L (100 mg/dl).
RESULTSThe prevalence rates of MS by NCEP definition were: 0.9%, 7.6% and 29.8% in the normal weight (control group), overweight and obese children, respectively, which were higher than the rates diagnosed by IDF definition with 0.1%, 5.2% and 28.6% in the three groups. The prevalence rates of individual MS component among obese children were: 81.6% for abnormal obesity, 47.7% for elevated BPs, 35.6% for high TG, 16.9% for low HDL-C, and 13.4% for IFG. Elevated BPs (29.8%), abnormal obesity (27.4%) and high TG (26.0%) were the leading three abnormalities among overweight children. With the increase of BMI, the clustering of MS components and insulin resistance (HOMA-IR) were remarkably increased. HOMA-IR significantly increased as the number of MS component increased.
CONCLUSIONSMS has been in an epidemic status among the obese schoolchildren in Beijing. Abnormal obesity, elevated BPs and high TG were the three most common metabolic abnormalities for overweight and obese children. The prevalence rates of MS by NCEP definition in the present study was higher than those diagnosed by using IDF definition.

OBJECTIVETo evaluate the role of sclerostin in bone loss of postmenopausal Chinese women with type 2 diabetes mellitus.
METHODSThe postmenopausal patients suffering from type 2 diabetes mellitus and age, body mass index, and duration of menopause matched healthy controls were enrolled into this cross-sectional study according to criteria of inclusion and exclusion. The serum sclerostin level and bone mineral density of the anterior-posterior lumbar spine (L1-L4), femoral neck, and total hip were determined by using a quantitative sandwich ELISA kit and dual X-ray absorptiometry, respectively. Meanwhile, the clinical and laboratory indexes of bone mineral metabolism were analyzed. Associations between serum sclerostin level and bone mineral density as well as bone turnover markers were evaluated by linear regression analysis.
RESULTSFinally, 265 postmenopausal women with type 2 diabetes and 225 non-diabetic women were recruited in the diabetic group and control group, respectively. Serum sclerostin level of the diabetic group was significantly higher than that of the control group (48.2±19.4 vs. 37.2±18.6 pmol/L, P<0.001) and was increased with age in both groups (diabetic group, r=0.374, P<0.001; control group, r=0.312, P<0.001). In type 2 diabetes patients, serum sclerostin concentration was positively correlated with hemoglobin A1c level (r=0.237; P=0.021). Biochemical bone turnover markers, intact parathyroid hormone and bone-specific alkaline phosphatase, were negatively associated with serum sclerostin level (r=-0.138, P=0.078 and r=-0.265, P<0.001). Conversely, the positive correlation between sclerostin and C-terminal cross-linking telopeptide of type I collagen was found in diabetic patients (r=0.354, P<0.001). Serum sclerostin levels of the diabetic group were positively correlated with bone mineral density of the lumbar spine, femoral neck, and total hip (r=0.324, 0.367, and 0.416, respectively; all P<0.001).
CONCLUSIONSSclerostin might participate in the pathogenesis of bone loss of type 2 diabetes. The high sclerostin level might serve as a marker of increased osteocyte activity in postmenopausal patients with type 2 diabetes mellitus.

PURPOSE: The objective of this study was to provide a trend analysis of the prevalence of diabetes relative to the socioeconomic, lifestyle, and physiologic risk factors among Korean adults aged over 30 years for a 10-year period using data from the Korean National Health and Nutrition Examination Survey. METHODS: Prevalence difference and the slope index of inequality were calculated for each risk factors using binomial regression by considering the repeated cross-sectional features of the data. The prevalence ratio and the relative index of inequality were calculated using log-binomial regression. Linear trend tests were performed using SAS 9.2. RESULTS: Crude prevalence of diabetes increased over the 10-year period, and was higher for men than for women. It was very high for adults 60 years or over, consistently increasing over time. The prevalence among unemployed men, women with higher level of stress, women with hypertension, and adults with serum triglyceride levels over 135 mg/dL increased over the 10-year period in comparison with the respective control group. CONCLUSION: Considering the rapid economic development and associated lifestyle changes in Korea, action should be taken to control the prevalence of diabetes by both preventing and consistently monitoring these identified risk factors using a public-health approach.

INTRODUCTIONThe aim of the study was to evaluate cerebral microangiopathy in type 2 noninsulin- dependent diabetes mellitus (NIDDM) patients and to establish potentially conducive factors.
MATERIALS AND METHODSA group of 34 patients with NIDDM and 31 gender- and agematched normal controls (NC) were assessed by extracranial Doppler ultrasound, in order to evaluate the pulsatility index (PI) and the resistance index (RI) in the internal carotid arteries (ICAs); transcranial Doppler was utilised to assess the same parameters in the middle cerebral arteries (MCAs). All patients underwent screening for favouring factors for cerebral vascular remodelling.
RESULTSOf the 34 NIDDM patients, 21 patients (61.76%) (subgroup A) presented with microangiopathic complications [of these, 19 patients (90.46%) had diabetic nephropathy (DN)] versus 13 NIDDM patients (38.24%) (subgroup B) without complications. In subgroup A, 16 patients (76.19%) had PI >1 and RI >0.7 in the ICAs and MCAs (changes consistent with cerebral microangiopathy) versus 5 patients (35.46%) in subgroup B, and no modifications in NC. Of the 19 patients with DN, 14 patients (73.68 %) had impaired haemodynamic indices. Univariate regression analysis showed the following risk factors for the cerebral haemodynamics changes: fibrinogen (F) (OR = 3.11), C-reactive protein (CRP) (OR = 2.40), duration of DM (OR = 2.40), proteinuria (OR = 1.80), serum creatinine (OR = 1.66). Multivariate regression analysis showed as predictors for impaired haemodynamic indices: duration of DM (HR =1.70), proteinuria (HR = 1.70). The haemodynamic indices in the ICAs correlated with duration of DM (r = 0.87, P <0.0001), F (r = 0.86; P <0.0001), CRP (r = 0.80; P <0.0001); in the MCAs with the duration of DM (r = 0.66, P <0.0001), F (r = 0.38; P <0.0001), CRP (r = 0.88; P <0.0001).
CONCLUSIONCerebral microangiopathy has a high prevalence in NIDDM patients. These cerebral vascular changes correlate with the duration of DM, parameters of inflammation, and proteinuria.
