RESUMEN
Objective To explore the relationship between glycosylated hemoglobin and pulse wave velocity in non-diabetic elderly people.Methods Totally 163 subjects were included after exclusion of liver or kidney disfunction,diabetes mellitus or malignant tumor.They were divided into two groups:group A (HbA1c＜5.7％) (n＝54) and group B (HbA1c 5.7％-6.4％)(n＝109).The age,pulse wave velocity,systolic blood pressure,diastolic blood pressure,blood chemistry and hypertension were compared between the two groups.Multi factor analyse was conducted to analyze the relative factors for pulse wave velocity.Results Systolic blood pressure was higher in group B than in group A (P ＜ 0.05).Multi-linear stepwise regression analyses suggested that age,hypertension,glycosylated hemoglobin were positively related to pulse wave velocity in non-diabetic elderly people (β values were 20.382,144.061,93.195,all P＜0.10).Conclusions Glycosylated hemoglobin is related to arterial stiffness in non-diabetic elderly people,it can be used as a predictive and control target of cardiovascular and cerebrovascular disease in old people.
RESUMEN
Objective To assess the efficiency of an iontophoresis-based screening method (EZSCAN) in the detection of impaired glucose tolerance (IGT),diabetes mellitus (DM) and metabolic syndrome (MS).Methods A total of 166 subjects without medical history of dysglycaemia underwent fasting plasma glucose (FPG) and HbA1c measurement and oral glucose tolerance test (OGTT) by using traditional or EZSCAN method.Variance analysis (GLM),SNK analysis,logistic regression analysis,and ROC analysis were used to evaluate the diagnostic value of those screening techniques.Results DM,IGT,normal glucose tolerance (NGT) +MS,and NGT were found in 4,26,25 or 111 participants,respectively.For traditional test,FPG of 7.0 mmol/L showed a lower sensitivity to detect DM (0%).The sensitivity of EZSCAN to detect DM,IGT or MS was 50%,77% and 64%,respectively.Conclusions FPG may have lower sensitivity to detect DM,although EZSCAN could show higher sensitivity to detect IGT,DM,and MS.
RESUMEN
Objective To investigate the prevalence of elevated serum alanine aminotransferase ( ALT) and ALT-related dysmetabolism and risk factors. Methods A total of 12 789 adult participated,with no hepatitis B virus infection or alcohol over-intake, received health check-up, including blood pressure measurement, blood glucose and lipid profile test, liver function evaluation and ultrasonography. The subjects were then assigned into two groups according to the serum level of ALT. Metabolic composition was compared between the two groups. Results The prevalence of elevated ALT activity was 8.69%. The waist circumstance,body mass index (BMI) ,systolic blood pressure (SBP) ,diastolic blood pressure (DBP) ,total cholesterol (TC) ,triglyceride (TG) , low-density lipoprotein cholesterol (LDL-C) , urine acid (UA) , fasting blood glucose (FBG) ,HbAlc,total bilirubin (TBIL) ,-y-glutamyltransferase (GGT) ,alkaline phos-phatase ( ALP) of the elevated ALT group were significantly higher than those of the normal ALT group. However,age and high-density lipoprotein cholesterol ( HDL-C) in the elevated ALT group were lower than those in the normal ALT group ( P < 0. 05 ) . The occurrence of overweight, obesity, hyperlipidemia, impaired fasting glucose,diabetes, increased DBP, hyperuricacidemia and fatty liver in the elevated serum ALT group was significantly more than that in the normal ALT group ( P < 0. 05 ) . Multiple logistic regression analysis demonstrated that fatty liver, DBP, BMI.TC, HbAlc were risk factors of elevated serum ALT. Conclusion Non-alcoholic fatty liver disease, lipid metabolic disorders and obesity may be the main risk factors of elevated ALT.
RESUMEN
Objective To investigate the relationship of lower urinary tract symptoms (LUTS)with ageing in elderly population of Beijing. Methods From January 2010 to July 2010, the males over 40 years of age, who came to take routine health examination in Beijing Hospital, received a questionnaire related to urinary symptoms. Eligible men were classified into age groups spanning 10 years, and the urinary symptoms of each group were analyzed. Results Among the 2357 males who were investigated, the incidence of urinary symptoms increased, and the satisfaction of urinate decreased with ageing. In 40-49 age group, 44.94 % of males owned at least one urinary symptom and 71.47% of males were satisfied with their symptoms. In over-80 age group, these figures were 94.97% and 27.67%, respectively. Each symptom was associated with the satisfaction. Nocturia was the commonest symptom in each age group. Conclusions LUTS are common in elderly males and the incidence increases with ageing. Nocturia is the commonest symptom in elderly males.
RESUMEN
@#Objective To explore dyslipidemia in the people in the part of enterprises in Beijing.Methods Total cholesterol, triglyceride, high-density lipoprotein cholesterol, etc., in blood were detected in the physical examination of 12908 subjects in enterprises in Beijing. Dyslipidemia was analysed for the distribution of gender and the trend of age.Results The findings showed that the occurrence of hypercholesteremia is 21.3% with 20.3% for male vs 23.0% for female; hypertriacylglycerolemia is 30.4% with 36.19% for male vs 20.49% for female; and low level of high-density lipoprotein is 6.5% with 9.4% for male vs 1.6% for female. The trend of dyslipidemia increased with age. The subjects with coronary artery disease and related high risk diseases, who need medicine care, occupied 80.6% of the subjects with dyslipidemia.Conclusion Dyslipidemia increases with age and so regular detection of lipid is necessary especially for the subjects with coronary artery disease and related high risk diseases.
