FINDINGS: A total of 274 venous blood was collected from normal healthy adults during the community screening programmes. The performance of POC devices, Afinion and Quo-test were compared to central laboratory HPLC method; Adams A1c HA 8160. Both POC devices showed good correlation to HA 8160 with r = 0.94 (p < 0.001) and r = 0.95 (p < 0.001) for Afinion and Quo-test respectively. The means difference were statistically higher between POC and HA 8160 with 0.23% (95% CI 0.19-0.26, p < 0.001) and 0.29% (95% CI 0.24-0.34, p < 0.001) for Afinion and Quo-test respectively.
CONCLUSIONS: Both POC devices could be considered in health clinics for diabetes management but not to be used for the diagnostic purposes.
METHODS: Two parameters were measured (i) rate of glucose uptake by 3T3-L1 adipocyte cells in-vitro (ii) degree of pancreatic destruction in streptozotocin-nicotinamide induced male diabetic rats receiving M. pumilum aqueous extract (M.P) (250 and 500mg/kg/day) as reflected by levels of pancreatic oxidative stress, inflammation and apoptosis. In the meantime, phyto-chemical compounds in M.P were also identified by using LC-MS.
RESULTS: M.P was found able to enhance glucose uptake by 3T3-L1 adipocyte cells in-vitro while its administration to the male diabetic rats causes decreased in the fasting blood glucose (FBG), glycated haemoglobin (HbA1c), total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL) levels but causes increased in insulin and high-density lipoprotein (HDL) levels, to near normal. Levels of oxidative stress in the pancreas as reflected by levels of lipid peroxidation product (LPO) decreased while levels of anti-oxidantive enzymes (SOD, CAT and GPx) in pancreas increased. Additionally, levels of inflammation as reflected by NF-κB p65, Ikkβ and TNF-α levels decreased while apoptosis levels as reflected by caspase-9 and Bax levels decreased. Anti-apoptosis marker, Bcl-2 levels in pancreas increased.
CONCLUSIONS: The ability of M.P to enhance glucose uptake and reduces pancreatic complications could account for its beneficial effects in treating DM.
RESEARCH DESIGN AND METHODS: NIDDM patients of Chinese, Indian, and Malay origin attending a diabetic clinic in Kuala Lumpur, Malaysia, were matched for age, sex, diabetes duration, and glycemic control (n = 34 in each group). Urinary albumin-to-creatinine ratio was measured in an early morning urine sample. Biochemical measurements included markers of the acute-phase response: serum sialic acid, triglyceride, and (lowered) HDL cholesterol.
RESULTS: The frequency of microalbuminuria did not differ among the Chinese, Indian, and Malay patients (44, 41, and 47%, respectively). In Chinese patients, those with microalbuminuria had evidence of an augmented acute-phase response, with higher serum sialic acid and triglyceride and lower HDL cholesterol levels; and urinary albumin-to-creatinine ratio was correlated with serum sialic acid and triglyceride. The acute-phase response markers were not different in Indians, with microalbuminuria being high in even the normoalbuminuric Indians; only the mean arterial blood pressure was correlated with urinary albumin-to-creatinine ratio in the Indians. Malay NIDDM subjects had an association of microalbuminuria with acute-phase markers, but this was weaker than in the Chinese subjects.
CONCLUSIONS: Microalbuminuria is associated with an acute-phase response in Chinese NIDDM patients in Malaysia, as previously found in Caucasian NIDDM subjects. Elevated urinary albumin excretion has different correlates in other racial groups, such as those originating from the Indian subcontinent. The acute-phase response may have an etiological role in microalbuminuria.
