Investigation into the blood biochemical parameters related to metabolic syndrome in the staffs of Hanoi medical University in 2007

Background: Metabolic syndrome is characterized by a group of metabolic risk factors in one person but not a real disease. For this reason, metabolic syndrome is underestimated by clinicians and individuals. Metabolic syndrome that was not detected and treated timely can cause serious diseases. Objectives: 1) To investigate the abnormal blood biochemical parameters related to metabolic syndrome. 2) To determine the abnormal ratio of these parameters. 3) To screen the metabolic syndrome among the staffs of Ha Noi Medical University. Subjects and method: 229 staffs underwent laboratory tests to diagnose for the metabolic syndrome. Abnormal blood biochemical parameters were defined as follows: Fasting blood glucose level increased 6.1mmol/l or more. Triglycerides level is 2.3mmol/l or more, HDL-cholesterol decreased to less than 1.03mmol/l for men and less than 1.24mmol/l for women. Total cholesterol level is 5.2mmol/l or more. CT to HDL-C ratio is more than 3.63 and LDL cholesterol level is 3.5mmol/l or more. Results. Rate of subjects with glucose intolerance or blood fasting glucose higher than 6.1mmol/L is 20.09%. Rate of subjects with dyslipidemia is 61.14%. Average levels of blood glucose, triglycerides and cholesterol increase with age. Number of staffs of Ha Noi Medical University have metabolic syndrome in 2007 are 32 persons (14%). M/F rate is equal and most common in persons over 45 years of age. Conclusion:There are significant number of staffs at the Ha Noi Medical University that had abnormal blood glucose and cholesterol levels related to metabolic syndrome.

Preliminary Quality Evaluation of Blood Biochemical Tests in some Provincial Laboratories, Districts and Privates in the North of Vietnam

Introduction: Quality control in medical laboratory includes internal quality control and external quality control is very necessary for the quality management of medical laboratory tests. However, many laboratories for different reasons have not carried out quality control, its benefits, as well as inadequately evaluated affected risks of laboratory test quality. \r\n', u'Objectives: Two objectives are set for the research. First, to evaluate the quality of blood biochemical tests in some of the provinces, districts and private laboratories in the North of Vietnam. Second, factors that affect the quality of the medical laboratory tests are also examined. \r\n', u'Subjects and method: In this study, human control serum of Biorad is sent as ordinary blood samples to the 6 provincial, 12 district and 10 private laboratories to analyze some normal blood biomedical indexes. We also collected the necessary information on staff, equipments, and chemicals\u2026of the laboratories.\r\n', u'Results: There are five main findings in the areas of (1) general information about the laboratories, (2) laboratory test results of blood biochemical indexes with true value at the normal level, (3) laboratory test results of blood biochemical indexes with true value at the pathological level (level 2), (4) the accuracy of laboratory test results based on the blood test sample level 1, (5) the accuracy of laboratory test results based on the blood test sample level 2. In general, the first results of analyzed biomedical indexes are very different by statistical calculation between laboratories. \r\n', u'Conclusion: The research results indicated that the quality of analyzed biomedical indexes in some laboratories is not ensured. It is necessary to find the reasons and the ways to resolve the problem. \r\n', u'

Concentration of Blood Homocystein in TYP 2 Diabetics

Introduction: Diabetes is a serious metabolic disease with chronic and acute complications, especially atherosclerosis. The increase of blood homocystein level is obviously related to blood injuries\u2019 in a number of diseases including diabetes. In Vietnam, blood Homocystein in Diabetics has not been comprehensively studied. \r\n', u'Objectives: The study was conducted with two surveyed groups. Determination of blood homocystein concentration in type 2 diabetics in comparison with a group of normal people. \r\n', u'Subjects and method: The study was conducted on a sample of 57 type 2 diabetics according to WHO-2001 standards and a group of 46 normal people. Concentration of blood homocystein was assayed by a competition fluorescence immunoassay, and by other experiments according to normal biochemical methods.\r\n', u'Results: The tHcy concentration in diabetics is 12.19 \xb1 3.47 mmo/L and in the normal group is 7.87 \xb1 2.26 IJmo/L. \r\n', u'Conclusion: The tHcy concentration in the 57 type 2 diabetics group has a statistically increasing mean in comparison with the normal group for both men and women. However, there is no comparative difference in the tHcy concentration of diabetics in gender and age categories. \r\n', u'

Concentration of serum Hcy and its relationship with other biochemical indexes in preeclampsia

Background: Preeclampsia is a major cause of maternal and perinatal mortality and morbidity, affecting 5 - 6% of all pregnancies. Recently, homocysteine (Hcy), a metabolite of amino acid methionine has been postulated producing oxidative stress, endothelial cell dysfunction, and alterations associated with preeclampsia. It is unclear whether high concentration of circulating Hcy causes preeclampsia, or whether this is a secondary phenomenon of metabolic alterations resulting from the disorder. Objectives: (1) Determining blood Hcy concentration in pregnancies in various severities of preeclampsia. (2) Discover the relationships between serum Hcy and other biological markers in preeclampsia. Subjects and method: This descriptive cross-sectional study consisted of 3 groups of pregnancies admitted to Thanh Nhan Hospital: 24 normal pregnant women, 28 pregnancies with non-serious preeclampsia, and 27 pregnancies with serious preeclampsia. Concentrations of blood Hcy of all participants were assayed by a competition fluorescence immunoassay (FPIA). Results: The mean concentration of serum Hcy during normal pregnancy was 5.2+/-1.0micromol/L compared with 7.1+/-1.8micromol/L among pregnancies with non-serious preeclampsia, and 11.7+/-2.9micromol/L among pregnancies with serious preeclampsia. Serum Hcy increased in pregnancies with renal dysfunction, elevated serum uric acid, and injuries of liver cells. Conclusion: Concentration of the serum Hcy in pregnancies with serious preeclampsia is significantly higher than that of pregnancies with non-serious preeclampsia, and the serum Hcy in pregnancies with non-serious preeclampsia is significantly higher than that of normal pregnancies. There are relationships between elevated serum Hcy in preeclampsia with level of kidney failure, injury of liver and increased levels of serum uric acid.

Relations between blood homocysteine levels and other paraclinical parameters in type 2 diabetics

Background: Macro vascular disease is a frequent complication and can rapidly progress in type 2 diabetics. The increase of blood homocysteine (Hcy) level is obviously related to an injury of blood vessels in certain types of diseases including diabetes. It is necessary to determine blood Hcy concentrations and find out its role in relation to other tests in type 2 diabetics. Objectives: (1) Determination of blood HbA1C concentration, urine micro albumin, and flow mediated dilatation (FMD) in type 2 diabetics. (2) Discover any relations between blood Hcy levels and other parameters in type 2 diabetics. Subjects and method: The prospective, descriptive, cross-sectional study was carried out on 57 type 2 diabetics diagnosed by WHO 2001 criteria. The concentrations of blood Hcy of all participants were assayed by a competition fluorescence immunoassay. Results: Concentrations of blood HbA1C in patients without and with controlling blood glucose were 10.6 +/- 2.2% and 7.2 +/- 0.3%, respectively. In type 2 diabetics, 35.1% of patients had positive micro-albuminuria (MAU}. FMD of patients with and without vascular damage were 4.19 +/- 1.83% and 8065 +/- 2.1%, respectively. The average concentration of blood Hcy in 57 type 2 diabetics was 12.19 +/- 3.47 micromol/L. Conclusion: Concentrations of blood Hcy in type 2 diabetics without controlling blood glucose were higher than those in the group with controlled blood glucose, but not significantly. Concentrations of blood Hcy between patients with MAU (-) and MAU (+) were significantly different. There is a reverse linear correlation between blood Hcy and FMD.

Protease and protease inhibitor in cancer management

Protease is responsible for many physiological functions and can act as growth factor for both malignant and normal cells in the processes of the cell division and DNA biosynthesis. There was clear relation between metastatic tumors and protease. The protease inhibitors found in the natural environment or synthesized but both have not been used in the treatment of human cancer. Currently, the protease inhibitors are studying thoroughly on their mechanism, action and application in the anti-cancer.

The DNA metylation in vertebral animal: significant and modulation

Review of the process basing on DNA showed that the DNA metylation occurs highly and suddenly increase of the gene number during change from convertebrate animal to vertebrate animal. So DNA metylation Þ is considered as a basic of this evolution. The DNA metylation plays an important role in gene expression, fetal growth and tumor generation in vertebral animal. Today, it is identified that the DNA metylation occurs in the 5th position of cytosine (5mC) and the first enzyme contributes the process of DNA metylation is DNA metyltransferase (Dmt).
