Background: The prevalence of metabolic syndrome (MetS) in adults in Thai Binh province was still high (28.4%). However, previous studies on the prevalence of MetS among the elderly were still limited and inconsistent. Therefore, The objective of this study was to examine gender differences in metabolic syndrome (MetS) characteristics and some associated factors. Materials and Methods: A convenience sample of 404 elderly outpatients was recruited from Thai Binh Medical University Hospital. The general information and history of falls, sleep quality score, smoking, alcohol use, and body mass index (BMI) of the subjects were collected through questionnaires, and each patient's height, Weight, waist circumference (WC), and other physical signs were measured. MetS was diagnosed based on the criteria of the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). Logistic regression analysis was used to analyze the risk factors of MetS and its components. Results: The prevalence of MetS in elderly females (36.0%) is higher than in males (18.5%) (p<0.001). The three component indices of MetS are low HDL-cholesterol ratio, high triglyceride (TG), and higher WC in females than males. In contrast, the two indices, high blood pressure (BP) and elevated blood sugar (BS), showed the opposite. Some factors associated with MetS in both genders are BMI, BS, and TG, but older men with a history of smoking [OR (95%CI), 3.2 (1.2-8.2)], and older women with a history of falls [OR (95%CI), 1.6 (1.1-2.4)] have a higher risk of MetS than other subjects. Conclusions: There were significant differences in MetS components in the two sexes. In additions, there are different factors related to the prevalence of MetS in both sexes: smoking history in men and history of falls in women.

Objective To investigate the anti-proliferative effects of 20-hydroxyecdysone isolated from the bark of Dacrycarpus imbricatus (Blume) de Laub. Methods Column chromatography was used for isolation of compounds from plant material. The structure of the isolated compound was identified by mass spectrometry and nuclear magnetic resonance techniques, including HSQC, HMBC, NOE-difference experiments. The isolated compound was tested for its anti-proliferative activity in acute myeloid leukemia (AML) and OCI-AML cells. Results Compound 1 was isolated from the ethyl acetate fraction of Dacrycarpus imbricatus barks by column chromatography. Its chemical structure was identified as 20-hydroxyecdysone (20HE), a cholestane-type ecdysteroid, by a combination of mass spectrometry and nuclear magnetic resonance spectrometric analyses. Our goal was to test the anti-proliferative activity of 20HE using the OCI-AML cell line. 20HE significantly decreased OCI cell number at a concentration of 1 mg/mL, whereas lower concentrations were ineffective. Moreover, this decrease was due to partial blockage of the G

Introduction: There are thousands of diabetes sufferers worldwide. In addition, there is an increased trend in Vietnam due to economic development, increased population, lifespan, and changing lifestyle. Insulin is a hormone, which is a natural protein. It plays an important role in the transformation of glucose in human and animal blood. Note, while insulin has not been produced in Vietnam, the production of recombinant Proinsulin is a premise for insulin. This study is based on a successful design of pET - 28a (+) Vector with recombinant Proinsulin codified gene.\r\n', u'Objectives: To define the human proinsulin codified gene and study the optimum conditions for the expression of proinsulin. \r\n', u'Subjects and method: To discover the appropriate conditions for the expression of proinsulin, including initial cell density, cultural temperature, IPTG concentration, and expression time. The product of the expression was confirmed by Sodium dodecyl sulfate - polyacrylamide gel electrophoresis (SOS - PAGE) and reconfirmed by Western blotting with His - Tag antibody. \r\n', u'Results: Proinsulin expression was successfully proved by SOS - PAGE and Western blotting. Four appropriate conditions for the expression were confirmed as highlighted in the Conclusion. \r\n', u'Conclusion: The appropriate conditions for expression of proinsulin: cell density was 00600 0.6 - 1.0; the cultural temperature was 300C; IPTG concentration was 0.4 mM; the length of the culture time was 20 hours. \r\n', u'

Background: Diabetes is a common chronic glucide metabolic disorder affecting hundreds of millions of people around the world. In Vietnam, the number of people with risk of type 2 diabetes is approximately 5 million. \r\n', u'Objectives: To discover the changes of blood biochemical parameters and mean body mass index (SMIJ waist circumference in individuals with diabetic risk factors). \r\n', u'Method: 95 people with diabetic risk factors were selected by screening. One group was in Ngoc Trao or Phu Son wards (n=52) and other group was in Sa Dinh ward (n=43). \r\n', u'Results: In Ngoc Trao and Phu Son wards: the prevalence of blood glucose, cholesterol triglyceride, HDL, LDL disorders and SMI>23 were 65.3%, 32.7%, 46.2%, 1.9%, 36.5%, 61.5%, respectively. In Sa Dinh ward: those were 62.8%, 29.7%, 44.2%, 2.3%, 34.9% and 67.4%, respectively. \r\n', u'Conclusion: Disorders of blood biochemical parameters accounted for very high rate in individuals with diabetic risk factors and could be considered main risk factors. \r\n', u'
