question:
To examine the lipid profile in Chinese type 2 diabetic patients and their relationship with anthropometric parameters, glycaemic control and cardiovascular mortality.', 'A consecutive cohort of 562 newly referred patients with type 2 diabetes to a hospital-based diabetes centre were examined in 1996. Subjects treated with lipid lowering drugs at the time of referral were excluded. A total of 517 subjects were followed up over a mean (+/-SD) period of 4.6 +/- 0.9 years. Glycated haemoglobin (HbA1c), fasting insulin and lipid profile and anthropometric parameters were documented at the time of recruitment. Cardiovascular mortality, mainly due to coronary heart disease and stroke, was ascertained using death registry and review of hospital case notes in 2001.', 'Of the 517 subjects (mean age of 54.0 +/- 14.0 years), 42.6% were men. In this cohort, 63.3% of subjects were either overweight (BMI > or = 23 kg/m2) or obese (BMI > or = 25 kg/m2) using Asian criteria. The mean (+/-SD) total cholesterol (TC), LDL-Cholesterol (LDL-C), HDL-Cholesterol (HDL-C) and geometric mean (x// antilog SD) of triglycerides (TG) were 5.6 +/- 1.3 mmol/L, 3.6 +/- 1.1 mmol/L, 1.3 +/- 0.3 mmol/L and 1.46x//1.90 mmol/L respectively. TC and LDL-C correlated positively with HbA1c, HDL-C negatively with BMI and WC (waist circumference), while TG positively with HbA1c, BMI, WC and HOMA (insulin resistance estimated using the homeostasis model assessment). During the 4.6 years follow-up period, there were 61 deaths giving a total mortality rate of 11.4%, of which 15 (25%) were because of cardiovascular events. Apart from age and disease duration, logarithm of TG was significantly associated with increased risk of cardiovascular mortality (p = 0.049, relative risk = 2.97, 95% CI 1.00-8.77).

question:
The treatment of choice for aortic valve insufficiency due to root dilatation has become root replacement with aortic valve sparing. However, root replacement with a synthetic graft may result in altered valve stresses. The purpose of this study was to compare the stress/strain patterns in the spared aortic valve in different root replacement procedures by means of finite element modeling.', 'Our finite element model of the normal human root and valve was modified to simulate and evaluate three surgical techniques: (1) "cylindrical" graft sutured below the valve at the anulus, (2) "tailored" graft sutured just above the valve, and (3) "pseudosinus" graft, tailored and sutured below the valve at the anulus. Simulated diastolic pressures were applied, and stresses and strains were calculated for the valve, root, and graft. Leaflet coaptation was also quantified.', 'All three root replacement models demonstrated significantly altered leaflet stress patterns as compared with normal patterns. The cylindrical model showed the greatest increases in stress (16%-173%) and strain (10%-98%), followed by the tailored model (stress +10%-157%, strain +9%-36%). The pseudosinus model showed the smallest increase in stress (9%-28%) and strain (2%-31%), and leaflet coaptation was closest to normal.

question:
To examine the hypothesis that induction of heat shock proteins in human endothelial cells (ECs) by either heat shock or sodium arsenite could prevent subsequent EC necrosis induced by activated human polymorphonuclear neutrophil leukocytes (PMNs).', 'Cultures of ECs were exposed to heat shock (42 degrees C, 30 to 60 minutes) or sodium arsenite (40 to 320 mumol/L) for 6 hours to induce the expression of a heat shock protein of 72-kd molecular weight (HSP-72). Activated PMNs were subsequently added to these ECs for 24 hours to evaluate the ability of HSP-72 to prevent activated PMN-mediated EC necrosis.', 'Neither EC necrosis nor apoptosis was induced by heat shock. Sodium arsenite (40 to 80 mumol/L) did not induce EC necrosis, although 320-mumol/L sodium arsenite caused a significant increase in EC necrosis. Sodium arsenite (80 to 320 mumol/L) also induced dose-dependent EC apoptosis. Endothelial cells exposed to heat shock and sodium arsenite (40 and 80 mumol/L) significantly attenuated subsequent EC necrosis induced by activated PMNs. However, sodium arsenite at 320 mumol/L aggravated activated PMN-mediated EC necrosis. Expression of HSP-72 was detected after ECs were treated both with heat shock and sodium arsenite (40 to 320 mumol/L) for 6 hours.
