The aim of this study was to determine the concentration of vascular endothelial growth factor A （VEGF-A） and its receptors in patients with well-controlled diabetes. Methods： The study was conducted on 31 patients with well-controlled type 2 diabetes without microor macroangiopathy. Thirty healthy volunteers were enrolled in a control group. Serum concentrations of VEGF-A, VEGF receptors 1 and 2 （VEGFR1 and VEGFR2）, fasting glucose, and lipid profiles were measured, and the plasma concentration of glycated hemoglobin （HbAlc） was determined. Results： No significant differences were observed between the concentration of VEGF-A, VEGFR1 or VEGFR2 in the subject group and that in the control group. Positive correlations were noted between the levels of VEGF-A, VEGFR2, and triglyceride, and there was a negative correlation between the levels of VEGFR2 and high-density lipoprotein （HDL）-cholesterel in the study group. Conclusions： The concentrations of VEGF-A and its receptors 1 and 2 in patients with well-controlled diabetes are comparable to those of healthy individuals, which may indicate that appropriate control of glucose levels delays the occurrence of vascular complications. A negative correlation between VEGFR2 and HDL-cholesterol levels, and positive correlations between VEGF-A, VEGFR2, and triglyceride levels, suggest that lipid abnormalities occurring in diabetes may be involved in the modulation of angiogenesis.展开更多

In addition, the study would analyze how the health issue related to diabetes is viewed and addressed in the community (Pakistan and Saudi Arabia) and would use the concepts of socio-ecological approach to self-management of Type 2 diabetes and explore the factors affecting the self-management practices in these countries. The other objective of this protocol is to examine the role of physical inactivity and obesity in the development of Type 2 diabetes and its self-management in middle-aged population living in rural area of Pakistan and to evaluate a lifestyle intervention (Physical Activity and Diet) in the management of Type 2 diabetes. The brief review conducted in this protocol design will identify the potential areas of health care which need attention including the overall functioning of community healthcare clinics to diabetes care in terms of recognizing the symptoms of diabetes to early detection and diagnosis, easy access to community doctors. This review will impress upon the need to recognize that in developing strategies and interventions to address diabetes, self-care, family support, community education and community ownership are important and it will be demonstrated by the comparison of two culturally diversified populations of Pakistan and Saudi Arabia in relation to the self-management of Type 2 diabetes.展开更多
