Objectives To compare the value of different criteria (WHO, IDF and CDS criteria) on the diagnosis of metabolic syndrome (MS) in the elderly people. Methods 2 456 elderly patients admitted to General Hospital of PLA for routine physical examination during 1996 to 2005 were involved in present study. The value of different criteria (WHO, IDF and CDS criteria) on the diagnosis of metabolic syndrome (MS) was compared. Results The incidences of MS in the involved patients were 27.2%, 27.0% and 42.6%, respectively, according to WHO, IDF and CDS criteria. The diagnostic coincidence of CDS and IDF criteria was 79.0%. For the 1759 cases with the waistline data, the incidences of MS were 32.3%, 37.8% and 53.8%, respectively, according to the above three criteria. The diagnostic coincidence of CDS and IDF criteria was 76.5 %. According to the criteria of WHO, IDF and CDS, central obesity was detectable in a rate of 35.9%, 49.6% and 52.2%, respectively. Hypertension was diagnosed in a rate of 61.6%, 72.4% and 61.6%, and abnormal glucose metabolism was found in a rate of 24.9%, 40.5% and 24.9%, respectively. The most common clinical symptom complex of MS was hypertension, impaired glucose tolerance and abnormal lipid metabolism. Conclusions A higher coincidence exists between CDS and IDF criteria for MS, but the incidence of MS is higher in CDS criterion compared to WHO and IDF criteria. It is indicated that more attention should be paid on the measurement of the waistline in the elderly people. It seems more appropriate that the waistline data in CDS criterion should be modified from 85cm to 90cm for the elderly people, however, this should be verified by more epidemiological investigation.

Objective To analyze the clinical features of aged men with hyperinsulinemia, and to explore its influence factors. Methods 521 aged persons belonging to the high-risk population of diabetes mellitus (DM) were given 75g oral glucose tolerance test (OGTT), and then divided into hyperinsulinemia group and normal insulin group according to the plasma insulin levels. Clinical features, glucose metabolism state, constituent ratio, complicating diseases, ? cell function and insulin resistance were compared between the two groups. Insulin resistance was determined by HOMA-IR, and ? cell function was determined by HOMA-?. The relationship between glycometabolic change and body weight was analyzed in hyperinsulinemia patients for a period of 2-10 years. Results 195 cases were in hyperinsulinemia group, and 326 cases were in normal insulin group. Compared with the latter, the subjects in hyperinsulinemia group showed higher values of BMI, waistline, fasting blood glucose (FBG), postprandial glucose (2hPBG), and systolic and diastolic blood pressure (SBP, DBP)(P

Objective To evaluate the feasibility of detecting peripheral artery disease (PAD) using ankle-brachial index (ABI) determined by an electronic sphygmomanometer in patients with type 2 diabetes mellitus (DM). Method The brachial blood pressure and the ankle blood pressure were measured in each upper limbs and lower limbs by the Doppler ultrasound method and the electronic sphygmomanometer method in fifty-nine DM patients who were selected from Department of Geriatric Endocrinology of General Hospital of PLA. ABI was calculated with the formula of ABI = ankle systolic blood pressure/ brachial systolic blood pressure. The measurement data were expressed as x?s. Then the data of systolic pressure and ABI were analyzed by paired Student's t tests and correlations. The related diagnosis criteria of PAD, such as sensitivity, specificity, positive predictive value, negative predictive value, and the global accuracy were calculated. Furthermore, the correlation of brachial blood pressure as measured by the electronic sphygmomanometer and the mercury column sphygmomanometer was compared. Results There were no significant differences but good correlations between the data of systolic pressures and ABI obtained as measured by two methods. The correlation for systolic pressure was: right upper limbs 0.92, P

Objective To reduce the birthrate of ?-thalassemia major and improve the quality of population. Methods 527 pregnant women and their spouses were screened at 12~26 weeks of gestation with hematological data to find out carriers of ?-thalassemia. The blood samples of the couples who were both carriers were analyzed with PCR-RDB method for prenatal gene diagnosis. The umbilical blood samples were examined to prove the results. Results There were 28 cases of ?-thalassemia out of 1054 individuals, the positive rate was 2.66%; the ratio of male to female was 1/1.15. As the result of prenatal gene diagnosis, among four fetuses at risk, one was completely normal while three were with ?-thalassemia major(one homozygous and two compound heterozygous) who were aborted within 2 weeks after prenatal gene diagnosis. Conclusions It suggests that the PCR-RDB assay is effective in preventing the birth of ?-thalassemia major and has clinical significance in improving the population quality.
