Type 2 diabetes mellitus (T2DM) is a common chronic metabolic disorder,it results from an interaction of environmental as well as genetic factors.There were several kinds of oral antidiabetic drugs (OADs),including biguanides,sulfonylureas,thiazolidinediones,and meglitinides,etc.Several genes have been identified to be associated with disease development and therapeutic outcomes.Inter-individual variations in the human genome affect both,risk of T2DM development and personalized response to identical drug therapies.Pharmacogenomics approaches focus on single nucleotide polymorphisms and their influence on individual drug response,efficacy and toxicity.Therefore,pharmacogenomics in T2DM is of great importance towards precision medicine which will greatly improve the efficacy of diabetes treatment.In this paper,antidiabetic drugs and related gene polymorphism researches are reviewed.

<p><b>OBJECTIVE</b>To assess a minipig model of acute myocardial infarction (AMI) established by percutaneous balloon occlusion using delayed-enhanced magnetic resonance imaging (DE-MRI).</p><p><b>METHODS</b>A minipig model of AMI was established by placement of a 2.0 mm×15.0 mm percutaneous transluminal coronary angioplasty balloon in the middle left anterior descending artery (LAD) through a percutaneous femoral puncture in the right inguinal region. The left anterior descending coronary artery (LAD) was occluded for 90 min, followed by assessment of the infarct size and cardiac function with DE-MRI, and the results were confirmed by pathological examination.</p><p><b>RESULTS</b>DE-MRI showed a mean infarcts size of 10.2∓2.9 cm3 in the minipig models. Compared to the control group, the minipigs with AMI had significantly increased end-diastolic and end-systolic volumes (P<0.05) with a decreased stroke volume, ejection fraction and cardiac output (P<0.001). These DE-MRI values were matched with the microsphere values obtained from short-axis slices in pathological examination.</p><p><b>CONCLUSION</b>We have established a feasible approach for evaluating minipig models of AMI as a platform for assessing the therapeutic effect of stem cell transplantation for AMI.</p>

Objective To investigate the cause of high cardiovascular lethality in patients with diabetics mellitus. Methods Sections from autopsied coronary arteries and myocardium of dead patients with non-insulin-dependent diabetics mellitus and 12 dead control subjects were used for histomorphometric studies. Results The coronary atherosclerotic lesion in diabetics patients was not different in severity from those in controls. Nor was there difference in number of myofibers or diameters of myocardic fibers and capillaries.But the capillary density and the ratio of capillary number to myocardic fiber number in diabetics group were significeantly reduced compared with control group(P<0.0 l),and the capillary basement membrane in the former was significantly thicker than in the latter(P<0.01).Conclision The decrease in number of capillaries and the thickening of basement membrane enhance myocardiac vulnerability to further ischemia and hypoxia,which may undelie high lethality of myocardiopathy in diabetic patients.

@#Post stroke depression (PSD) is a common complication after senile cerebrovascular diseases. It influences both physical and mental health of the elderly severely. So, the attention should be paid to not only the medical cares but also the function and mental rehabilitation, in order to improve the qualities of PSD patients' lives and decrease the death rate.
