RESUMO
Objective To assess the effect of meal replacements on body weight control and blood glucose and lipid profile by adjusting their nutrients intake with a meal replacement approach.Methods One hundred and thirty subjects were randomly divided into intervention group (100 subjects) and control group (30 subjects).Besides dietary consulting and health education,all subjects in intervention group received a dietary treatment with 2 meal replacements each day over a shot-term (3 months).All subjects were evaluated by recording the body measurements and laboratory data every 2 weeks.Results Compared with the baseline,mean percentages of BMI loss and decrease in waist circumference were 7.2 ％ and 6.5％ for intervention group(P＜0.01) by week 12.Meanwhile,systolic blood pressure,diastolic blood pressure,fasting plasma glucose,and triglyceride levels were significantly reduced (P＜0.01),showing significant difference compared with control group at the same period(all P＜0.01).Conclusion The meal replacement approach evaluated is an effective strategy to control body weight,and thus to achieve great improvement in the prevention of obesity-related diseases.
RESUMO
The association of the serum phospholipid fatty acid components with high-sensitivity C reactive protein in patients with metabolic syndrome and type 2 diabetes mellitus was investigated.Saturated fatty acid in patients with metabolic syndrome and type 2 diabetes mellitus was increased (45.98±1.55 vs 42.05±2.04,P＜0.01),while polyunsaturated fatty acid was decreased(42.38±1.93 vs 46.60±2.06,P＜0.01),and high sensitivity C reactive protein was significantly increased[(6.36± 1.28 vs 0.79±0.45) mg/L,P＜0.01)].
RESUMO
Objective To investigate the relationship between serum omega-3 polyunsaturated fatty acid (ω-3PUFA) and insulin resistance(IR) in patients with type 2 diabetes mellitus and non-alcoholic fatty liver disease (NAFLD). Methods This trial involved 51 patients of type 2 diabetes mellitus with NAFLD (G4 group), 50 patients of type 2 diabetes alone(G3 group), 45 patients of NAFLD alone (G2 group) and 42 healthy control subjects (G1 group). Serum ω-3PUFA profile was analyzed with capillary gas chromatography. Insulin resistance was assessed by homeostasis model assessment (HOMA-IR). ALT, AST, γ-glutamyltransferase(GGT) and serum lipids were measured. Results The levels of HOMA-IR were higher in G4 group than those in G3, G2 and G1 group(4. 90 ± 2. 54 vs 2. 38 ± 1.23, 2. 20 ± 1.15, 1.13± 0.42;P<0.05). The level of ALT, AST, GGT, TC, TG, LDL-C were higher in G4 group than those in G3, G2 and G1 group(P < 0. 05). The level of ω-3PUFA was signifieantly lower in G4 group than those in G3, G2 and G1 group(5.68 ±2.02 vs 7. 17 ±2. 38, 6.97±2.32, 10.08±2.76;P <0.05). ω-3PUFA cocentration was negatively correlated with HOMA-IR, TC, TG and LDL-C (r = -0.491, -0. 376, - 0. 462, - 0. 408, P < 0. 05). Conclusions Serum ω-3 PUFA is significantly decreased in patients with type 2 diabetes mellitus and NAFLD. Serum ω-3PUFA is negatively correlated with insulin resistance. ω-3PUEA plays a very important role in the development of diabetes mellitus and NAFLD.
RESUMO
Objective To investigate the status of the knowledge of metabolic syndrome and their demand situation among community nurses and discuss the community nursing intervention on metabolic syndrome. Methods A survey about the knowledge and its needs of metabolic syndrome was conducted in community nurses of the practice bases of the nursing school of Zhejiang Traditional Chinese Medical University by selfdesigned questionnaires. Results 58.8% of the communities had carried out the prevention of metabolic syndrome, and standard administration had been applied in 43.3% among them. 40.8% and 42.9% nurses were not clear about the diagnosis and prevention of metabolic syndrome respectively. 100.0% nurses agreed that corresponding training was necessary for them. Conclusions The education and training of the knowledge about metabolic syndrome must be enhanced for community nurses, and the intervention measures should be reinforced to improve the rate of diagnosis , cognition rate, control rate in order to improve the people's health and reduce the social and personal burden.
RESUMO
The association of the serum phospholipid fatty acid components with lipid profiles in patients with newly-diagnosed type 2 diabetes mellitus was investigated.Saturated fatty acid in patients with newly diagnosed type 2 diabetes mellitus was increased(48.79±1.55 vs 42.58±1.96,P<0.01),whereas monounsaturated fatty acid and polyunsaturated fatty acid were decreased(10.72±1.53 vs 12.09±1.32,33.41±2. 16 vs 35.79±2.41.6.08±1.66 vs 9.54±1.54,all P<O.01).
RESUMO
OBJECTIVE To find out the situation of peri-operational lower respiratory tract infection in inpatients with congenital heart disease of left to right shunt and provide evidence for clinical prevention and treatment.METHODS Peri-operational lower respiratory tract nosocomial infection in 2 564 cases of congenital heart disease with left to right shunt during Jan 2003 to Dec 2005 was analyzed retrospectively.RESULTS The incidence rate of lower respiratory tract infection was 11.27% among 2 564 cases.The incidence rate was 15.51% in patients less than 2 years old.The most common pathogen was Pseudomonas aeruginosa(18.60%).The death rate in cases with lower respiratory tract nosocomial infection was higher than these non-infection cases.CONCLUSIONS Pulmonary congestion,less than 2 years old,mechanical ventilation and antibiotics abuse are main causes of lower respiratory tract nosocomial infection in patients with congenital heart disease with left to right shunt.Nosocomial infection can increase death rate.
RESUMO
Objective: A high-performance liquid chromatographic (HPLC) procedure with a fluorescence detector was developed to rapidly separate ?,?,?,?- tocopherol isomers in human serum Methods: The HPLC system consisted of Inertsil silica column (100-A, 3?m,4.6mm?250mm) and 7% (v/v) methyl-tert- butyl ether in n-hexane as mobile phase . Prior to HPLC, the serum sample wa deproteined by ethanol (BHT 0.0625%) and the tocopherol isomers were efficiently extracted in thei original isomeric conformations using n-hexane-ethyl acetate (5:1) in the presence of 2,6-bi-buty p-methylphenol (BHT). Result: The quantification limits, defined as the lowest quantitatively measurable concentration of the different compounds (ng/ml) are calculated according to the experiment:?-tocophero 1.0,?-tocopherol 1.0,?-tocopherol 0.5,?-tocopherol 0.5. The recovery rates are between 95%~105% Correlation coefficients are over 0.999 when the concentration is between 5 ng/ml~5 ?g/ml. Conclusion This technique is suitable for assay of tocopherol isomers in human serum at all ages.

Methods MTT assay was employed to determine cell proliferation and its inhibition. The level of NO was measured by enzyme reduction method. Results The MTT values of MC3T3-E1 cells under the 2.5,5.0,10.0 ?mol/L of sodium orthovanadate were 0.3380?0.0045, 0.3400?0.0141, 0.3840?0.0313 respectively, which were higher than in control group (0.2540?0.0167)(P
RESUMO
The serum levels of soluble E selectin (sE selectin) and soluble vascular cell adhesion molecule 1 (sVCAM 1) were determined by ELISA in impaired glucose tolerance (IGT) group (62 cases), normal glucose tolerance (NGT) group (24 subjects), and diabetes mellitus group (23 cases). Serum sVCAM 1 level in the IGT group was significantly higher than that in the NGT group (P
