[Metabolic syndrome increases Framingham risk score of patients with type 2 diabetes mellitus].

OBJECTIVE: To assess the impact of metabolic syndrome(MS) on Framingham risk score(FRS) in patients with type 2 diabetes mellitus (T2DM). METHODS: The anthropometric and biochemical data of 1708 patients with T2DM admitted in hospital from May 2008 to April 2013 were retrospectively analyzed, including 902 males and 806 females with a mean age of 57.1±11.8 years (20-79 years). Diagnosis of MS was made according to the criteria of the Adult Treatment Panel Ⅲ Criteria modified for Asians. RESULTS: Compared to non-MS/T2DM patients, MS/T2DM patients had higher waist circumference, body weight, body mass index, systolic and diastolic blood pressure, fasting C peptide, total cholesterol, triglyceride, and LDL-C (P<0.05), while lower HDL-C (P<0.01). Both FRS [13.0(10.0, 15.0) vs 11.0(9.0, 13.0) in male,15.0(12.0, 18.0) vs 12.0(6.0, 14.8) in female,P<0.01)] and 10-year cardiovascular risk [12.0%(6.0%, 20.0%) vs 8.0%(5.0%,12.0%) in male,3.0%(1.0%, 6.0%) vs 1.0%(0.0%, 2.8%) in female,P<0.01] were higher in MS/T2DM patients than those in non-MS/T2DM patients.Both FRS and 10-year cardiovascular risk were increased with the components of MS. CONCLUSION: T2DM patients with MS have more cardiovascular risk factors, higher FRS and 10-year cardiovascular risk.

Concentration of serum leptin and age in Chinese women and comparison with other races / 中南大学学报(医学版)

OBJECTIVE@#To determine the relationship between concentration of serum leptin and age in females, and to establish the reference value and compare it with other races.@*METHODS@#Serum leptin concentration of 690 adult healthy women (aged 20 approximately 81 years) was measured with ELISA.@*RESULTS@#The serum leptin concentration increased with age (r=0.224, P<0.001), and cubic regression was the best-fitting model. Leptin concentration had significant positive correlation with weight (r=0.574) and body mass index (r=0.618). The geometric mean of leptin concentration in normal weight, overweight and obesity was (8.94+/-1.82), (17.6+/-1.89), and (34.7+/-1.69) microg/L, respectively, with significant difference among the 3 groups (P<0.001). Leptin in pre-menopause, peri-menopause and post-menopause women was (9.68+/-1.81), (11.7+/-1.89), and (11.4+/-2.21) microg/L, respectively. The reference value of serum leptin in normal weight females was 5.30 approximately 12.6 microg/L. The curve-fitting of leptin with age in this group was significantly lower than American non Hispanic White (NHW), non Hispanic Black (NHB), and American Mexican (AM) females.@*CONCLUSION@#This study provides reliable reference value of serum leptin in adult women and discovers ethnic difference with American NHW, NHB, and AM females.
