Diabetes mellitus is a common problem, and female sexual dysfunction is one of its complications in diabetic women. Recent studies show that the major risk factors of sexual dysfunction in diabetic women are diabetes-induced vascular disease, neuropathy, endocrine abnormalities and psychological problems and so on. This article outlines the advances in the recent studies of female sexual dysfunction in diabetic women.

In order to investigate the risk factors of ischemic brain stroke (IBS) in diabetic patients, we analyzed 416 cases selected from 6239 diabetic patients admitted to Severance Hospital from Jan. 1983 to Dec 1987. Two hundred and eight cases had IBS. The other 208 cases without IBS were selected as a control group by a stratified random sampling method. The two groups were compared using various clinical characteristics of diabetes mellitus (DM) and known risk factors of IBS. In diabetics with IBS, the duration of DM was longer (9.2 +/- 7.1 years), hypertension was more frequently associated (68.2%) and the serum cholesterol level was higher (213.0 +/- 55.2 mg/dl) than in diabetics without IBS (7.6 +/- 7.1 years, 32.1% and 192.1 +/- 44.8 mg/dl, respectively). By means of Stepwise Logistic Regression Analysis (SLRA), it was found that the strong risk factors were hypertension and serum cholesterol level. The serum triglyceride level, type of DM and response to diabetes treatment were also thought to be risk factors of IBS by the retrial of SLRA of residuals after exclusion of hypertension and serum cholesterol level. IBS was not significantly related to the duration of DM, fasting blood glucose level, body weight, glycosylated hemoglobin value, and serum high-density lipoprotein-cholesterol level.

We examined whether alterations in vascular endothelial function and early structural changes in atherosclerosis are associated with microvascular complications in patients with type 1 diabetes mellitus (DM). Flow-mediated dilation (FMD) of the brachial artery and carotid intima-media thickness (IMT) measurement were performed in 70 young adults (aged 19 to 35 yr), 48 with type 1 DM, and 22 normal controls. Patients with diabetes had a lower peak FMD response (7.8+/-3.9 vs. 11.1 +/-1.9%, p<0.001) and increased IMT (0.51+/-0.10 vs. 0.42+/-0.07 mm, p<0.001) compared with controls. Twenty (41.7%) of the patients had microvascular complications including neuropathy, nephropathy, or retinopathy. In these complicated diabetic patients, we found a lower FMD response (6.1+/-2.5 vs. 9.9+/-3.5%, p=0.001) compared with diabetics without microvascular complications. The presence of microvascular complications was also associated with older age and longer duration of the disease. However, no differences were observed in IMT, body size, blood pressure, HbA1c, C-reactive protein, low-density lipoprotein or high-density lipoprotein cholesterol levels between complicated and non-complicated patients. Endothelial dysfunction and early structural atherosclerotic changes are common manifestations in type 1 DM, and endothelial dysfunction is thought to be an early event in the atherosclerotic process and important in the pathogenesis of microvascular complications.

OBJECTIVETo understand the relationship between prevalence rates of chronic diabetic complications and related macro-vascular diseases and hypertension, to provide evidence for diabetes prevention and control.

METHODSTo retrospectively analyze the clinical and laboratory data on 24 496 in-patients with diabetes during Jan. 1, 1991 to Dec. 31, 2000 from 30 provinces, municipalities and autonomous regions.

RESULTSThe prevalence rate of hypertension was 31.95%. The prevalence rates of other chronic diabetic complications and related macro-vascular diseases were 12.2% for cerebrovascular diseases, 15.9% for cardiovascular diseases, 5.0% for lower extremity vascular diseases, 34.3% for eye diseases, 33.6% for nephropathy and 60.3% for neuropathy, with a total rate of chronic diabetic complications and macro-vascular diseases of 73.2%. Hypertension was related with all kinds of chronic diabetic complications and macro-vascular diseases odds ratio (OR) of related systolic blood pressure was 1.148 - 1.866, and OR related diastolic was 1.141 - 1.242.

CONCLUSIONSThe prevalence rates of chronic diabetic complications and related macro-vascular diseases of in-patients with diabetes mellitus were much higher than those of non-diabetics, and was close to the levels seen in the western countries. Hypertension, especially high systolic blood pressure was the most important risk factor of chronic diabetic complications and the related macro-vascular diseases.

OBJECTIVETo evaluate medium-long term patency of below-knee bypass on patients who suffered from diabetic lower limb ischemia.

METHODSClinical and follow-up data of 51 patients was retrospectively analyzed who underwent 56 below-knee bypass because of diabetes from November 2001 to December 2006. There were 35 male and 16 female with an average age of 68 years. They endured 26 months ischemic time lag in average, and had suffered from diabetes for 11 years. All of the patients were performed bypass to below-knee (posterior tibial, anterior tibial or peroneal) arteries. Kaplan-meier method was applied. The subgroups of different operative methods and different out-flow vessels were compared by Log-rank tests.

RESULTSAn average follow-up time of 23 months was achieved, and lost-follow-up rate was 15%. The total 1- and 5-year primary patent rates were 68% and 54% respectively, secondary patent rate were 70% and 60% respectively, limb salvage rates were 69% and 65%, survival rates were 82% and 60%. One year (3 years) of patent rate(s) of operative method subgroups of femoral-popliteal-infrageniculate bypass with composite grafts, femoral/popliteal-infrageniculate bypass with artificial grafts and femoral/popliteal-infrageniculate bypass with autologous veins were 70% (50%), 33% (33%) and 70% (70%) respectively. One year (4 years) of patent rate(s) of out-flow vessel subgroups of posterior tibial artery, anterior tibial artery and peroneal artery were 65% (60%), 80% (53%) and 77% (66%) respectively. However, both subgroups did not show any statistic differences by log-rank tests.

CONCLUSIONSPartial or whole autologous veins as bypass grafts should be chosen when infrageniculate bypass is considered in diabetic patients. Considerable patent rates are acceptable no matter what kinds of out-flow vessels are chosen.

OBJECTIVETo identify the potential predictors of restenosis after bare mental stent (BMS) deployment in diabetic patients in Chinese diabetic patients.

METHODSWe retrospectively analyzed all patients implanted with BMS (n = 1126 with 2376 lesions) in our department from 2002 to 2004. The multivariate logistic regression analysis was made to compare the clinical and angiographic characteristics between diabetic patients with and without restenosis. Restenosis was defined as > or = 50% diameter stenosis within the stent and 5 mm in adjacent.

RESULTSThe 6-month follow-up angiograms were available in 889 out of 1126 patients (78.9%) and 151 out of 889 patients (17%) were diabetic patients. Restenosis rate in nondiabetic patients group was 21.2% and 35.9% in diabetic patients (P < 0.001). The predictors of restenosis in diabetics were reference vessel diameter (< or = 3.0 mm), length of lesion (> 15 mm) and insulin use (P < 0.05). The restenosis predicting model showed that reference vessel caliber was the paramount predictor for restenosis in diabetic patients.

CONCLUSIONSRestenosis rate post BMS implantation is significantly higher in diabetic patients compared to non-diabetic patients. Vessel caliber, lesion length and insulin use are predictors of restenosis in diabetic patients. Diabetic patients with reference vessel diameter of > 3.0 mm combined with lesion length < 15 mm and non-diabetic patients with lesion length < 15 mm regardless of the vessel caliber could be treated with BMS since the predicted restenosis rate is lower than 15% in these patients, otherwise DES would be a better choice.

BACKGROUNDPlasma galectin-3, a mediator of fibrogenesis and inflammation, its potential to associate with type 2 diabetes (T2DM) is poorly investigated. Here, we explored its interaction with the serum galectin-3 and vascular complications.

METHODSWe conducted a population-based cross-sectional survey in Zhejiang, China involving 165 men and 119 women (age range, 43 - 84 years), investigating the relationship between serum galectin-3 and vascular disease in patients with T2DM.

RESULTSSerum galectin-3 was higher in subjects with T2DM than that in control participants (27.4 vs. 17.6 ng/ml, P < 0.001). Compared with subjects with galectin-3 values in the lowest quartile, those with values in the highest quartile had an increased likelihood of vascular complications (4th quartile odds ratio (OR) 2.52, 95% confidence interval (CI), 1.25 - 4.07). Increased risk of micro- or macrovascular complications correlated with serum galectin-3 concentration (ORs 11.4 and 8.5, respectively). An increased number of vascular complications was associated with high serum galectin-3 levels (P < 0.05). Patients with serum galectin-3 levels > 25 ng/ml had an elevated risk of diabetes relative to patients with levels < 10 ng/ml (OR for any vascular complication 2.64, for heart failure 3.97, for nephropathy 4.09, for peripheral arterial disease (PAD) 4.18; all P < 0.05). Complication risk was higher in patients with neurogenic, stroke, or retinopathy complications, but this difference was not significant after risk factor adjustment. Serum galectin-3 levels correlated with diabetes duration, C-reactive protein (CRP) levels, and albuminuria.

CONCLUSIONHigh galectin-3 values were associated with increased odds of developing heart failure, nephropathy, and peripheral arterial disease in patients with T2DM.

OBJECTIVETo study the clinicopathological features of diabetic microangiopathy in liver and diabetic hepatosclerosis (DHS) of elderly male with type 2 diabetes mellitus (T2DM).

METHODSOne hundred and twenty autopsy cases with T2DM (diabetic group) and contemporary 48 cases, non-diabetic and glucose tolerance abnormal, matched by gender and age (control group) were selected in the study. Cases with the cirrhosis and fibrosis of liver caused by other foregone etiological factors were excluded. The histopathological changes of microangiopathy in liver, hepatic portal areas and hepatic sinusoid were investigated by HE staining, histochemical and immunohistochemical stain methods. The clinical data of diagnostic DHS cases were analyzed.

RESULTS(1) Microangiopathy was observed in 54.2% (65/120) cases of diabetic group. Histological features: microangiopathy was found in interlobular arteries (especially in arteriole, the lumen diameter < 100 µm), which included endothelial denudation, eosinophilic material deposition in the tunica intima of artery, and eccentric intimal thickening. The smooth muscle fibers of tunica media were hyperplastic or atrophy. Fibroplasia and collagen deposition were found in the tunica adventitia of artery. Arterial lumina showed stenosis and occlusion. Microangiopathy was seen in 16.7% (8/48) cases of the control group. There was statistically significant difference between the two groups (χ(2) = 19.622, P < 0.01). (2) The fibrosis and sclerosis of portal areas were detected in 55.8% (67/120) cases of T2DM group. Hyaline collagen fiber tissues was deposited around interlobular arteries, interlobular veins and interlobular bile ducts, resulting in enlargement of the portal area and the secondary atrophy and disappearance of portal triad. The fibrosis and sclerosis of portal areas were detected in 22.9% (11/48) cases of the control group. There was a statistically significant difference between the two groups (χ(2) = 14.936, P < 0.01). (3) The pathological features of 14.2% (17/120) cases were consistent with the diagnosis of DHS. The fibrous tissue extended from fibrosis or sclerosis of portal areas, or eosinophilic material deposition in the hepatic sinusoid in non-zonal pattern. The results of histochemical staining showed collagen fiber deposition in hepatic sinusoid. Stainings for Collagen IV, SMA, CD34 were found in the hepatic sinusoid. The sclerosis of hepatic sinusoid was not detected in any case in the control group.Overall, 13/17 and 11/17 DHS cases had liver microangiopathy and portal areas sclerosis respectively. Diabetic nephropathy was seen in 10 of 17 DHS cases. Among the 17 cases, 7 cases showed ALP elevation, of which there were 3 cases with ALT and AST mild elevation.

CONCLUSIONSDiabetic microangiopathy is common in the liver of elderly men with T2DM. And DHS is associated with diabetic microangiopathy. Fibrosis and sclerosis of portal areas may be the early or concomitant changes of DHS on histological ground. DHS is one of the complications of T2DM.
