Asians are more susceptible to type 2 diabetes mellitus (T2D) and its coronary heart disease (CHD) complications than the Western populations, possibly due to genetic factors, higher degrees of obesity, insulin resistance, and endothelial dysfunction that could occur even in healthy individuals. The genetic factors and their mechanisms, along with gene-gene and gene-environment interactions associated with CHD in T2D Asians, are yet to be explored. Therefore, the objectives of this paper were to review the current evidence of genetic factors for CHD, summarize the proposed mechanisms of these genes and how they may associate with CHD risk, and review the gene-gene and gene-environment interactions in T2D Asians with CHD. The genetic factors can be grouped according to their involvement in the energy and lipoprotein metabolism, vascular and endothelial pathology, antioxidation, cell cycle regulation, DNA damage repair, hormonal regulation of glucose metabolism, as well as cytoskeletal function and intracellular transport. Meanwhile, interactions between single nucleotide polymorphisms (SNPs) from different genes, SNPs within a single gene, and genetic interaction with environmental factors including obesity, smoking habit, and hyperlipidemia could modify the gene’s effect on the disease risk. Collectively, these factors illustrate the complexities of CHD in T2D, specifically among Asians.

Background: The present review article considers some chronic diseases of vascular and metabolic genesis, the causes of which may be mitochondrial dysfunction. Very often, in the long course of the disease, complications may occur, leading to myocardial infarction or ischemic stroke and as a result, death.In particular, a large percentage of human deaths nowadays belongs to cardiovascular diseases such as coronary heart disease (CHD), arterial hypertension, cardiomyopathies and type 2 diabetes mellitus. Objective: The aim of the present review was the analysis of literature sources, devoted to an investigation of a link of mitochondrial DNA mutations with chronic diseases of vascular and metabolic genesis, Results: The analysis of literature indicates the association of the mitochondrial genome mutations with coronary heart disease, type 2 diabetes mellitus, hypertension and various types of cardiomyopathies. Conclusion: The detected mutations can be used to analyze the predisposition to chronic diseases of vascular and metabolic genesis. They can also be used to create molecular-cell models necessary to evaluate the effectiveness of drugs developed for treatment of these pathologies. MtDNA mutations associated withthe absence of diseases of vascular and metabolic genesis could be potential candidates for gene therapy of diseases of vascular and metabolic genesis.

Abstract Background Medical service for the older patients is a worldwide challenge for public health system. Telemedicine can provide convenient and effective medical service for older patients. But the existing telemedicine models rely upon a direct communication between a doctor and a patient via the Internet but the doctor would be unable to give the patient a direct physical examination, it may lead to diagnostic errors. A new model of telemedicine jointly performed by general practitioners in community health centers and specialists in a university teaching hospital has been established. It is supervised by the government health department and is free for older patients. However, medical service demands of older patients in different age groups applying the new telemedicine are not well characterized. This study is to analyze medical service demands of older patients in different age groups applying the new telemedicine. Methods 472 older patients (aged ≥ 60) were enrolled and were divided into the young older group (aged 60 to 74), the old older group (aged 75 to 89) and the very old group (aged ≥ 90) according to the age stratification for older people defined by World Health Organization. Proportion of the top 10 diseases of older patients of different age groups was analyzed. Results Coronary heart disease and type 2 diabetes mellitus were identified as the top two diseases in the older patients and the young older patients as well as the old older patients applying the new telemedicine. Conclusions The new telemedicine model can provide effective free medical services to older patients. Different medical service demands were identified in different age groups of older patients. Coronary heart disease and type 2 diabetes mellitus were the main diseases of the older patients and young older patients as well as the old older patients applying the new telemedicine. Results of this study will provide basis for the health administrative departments to formulate health policies for older patients. Familiar with the main diseases in different age groups of older patients may provide better medical services to older patients.
