ABSTRACT
Objective:To investigate the distribution of uric acid in different occupation, age and gender groups, and changes of prevalence of hyperuricemia (HUA) and its influencing factors in healthy adults who receiving physical examination in Nanjing.Methods:The study was conducted in 107 478 subjects who received physical examination from 2012 to 2016. The prevalence of HUA in different genders and different years was compared. Subjects were divided into non-HUA and HUA groups according to serum uric acid. The differences in metabolic indicators and ages between two groups were analyzed. Uric acid levels among different occupations were evaluated. A multivariate logistic regression analysis was used to estimate the odds ratios ( OR) of HUA. Results:The total HUA prevalence was 14.9%, in which the prevalence of HUA in men was significantly higher than that in women [20.5%(15217/74339)vs .2.5%(818/33139), P<0.01]. The prevalence of HUA in men sustained at a high level, while that in women trended to decrease during the five years. The prevalence of HUA increased with age in women (1.0%, 0.7%, 0.9%, 2.7%, 3.8% and 9.6% in subjects within 20-29, 30-39, 40-49, 50-59, 60-69 and ≥70 age groups, respectively, Pfor trend<0.01). The percentages of hypertension, hyperlipidemia and diabetes, and body mass index (BMI) in both men and women were significantly higher in HUA group than those in non-HUA group ( P≤0.01). Among all occupations, subjects in health care had the lowest levels of uric acid (298±91 μmol/L) and prevalence of HUA (10.4%), while, those in public security had the highest levels of uric acid [(342±82) μmol/L] and prevalence (16.5%). Multiple logistic regression analyses revealed that males, high triacylglycerol, high cholesterol, obesity and certain occupation were significantly associated with HUA. Conclusions:The prevalence of HUA in men is significantly higher than that in women. It increased with ages in women. Subjects in health occupations had the lowest levels of uric acid and HUA prevalence, while, those in public security had the highest levels among the six occupations. Obesity, hyperlipidemia, hypertension, occupations and males are positively associated with HUA.
ABSTRACT
Objective To observe the availability and safety of ventricular septal defect (VSD) occluder in infants and young children with large patent ductus arteriosus (PDA) associated with severe pulmonary hypertension.Methods Five patients (1 male and 4 fomale) of large PDA aged 5 months to 3 years,weighted from 5.1 to 15 kg,body surface area (BSA) 0.37-0.58 m2 underwent transcathter intervention with concentric VSD occluders from June 2008 to May 2009.Arterial ducta were tube-like and their diameters were 5.7 to 8.5 mm,with ulmonary vascular resistance from 4.8 to 5.7 Wood Unit,Qp/Qs 3.4-4.6.Three patients were given Bosentan after intervention.Results The large PDAs were successfully closed with VSD occluders,including 1 concentric perimembranous VSD occluder and 4 muscular VSD occluders.They all discharged 4 to 5 days with hidrosis and weight improved.Echocardiogram indicated VSD occluder was stable,no residue shunt and no stricture of left pulmonary artery and descending aorta were found.According to tricuspid and pulmonary regurgitation,pulmonary arterial pressure decreased differently and returned to normal after 6 months follow-up.Conclusion VSD occluder is available and effective to close large PDA associated with severe pulmonary hypertension in inrants and young children,but more cases and long-term follow-up are necessary.
ABSTRACT
Objective To investigate the effects of adiponectin on the development of atherosclerosis.Methods The in vivo role of adiponectin on the development of atherosclerosis in rabbits was investigated mainly using adiponectin-producing adenovirus(Ad-APN)and intravascular ultrasound(IVUS).On day 14 after Ad-APN local transfer to the intima of abdominal aortas,abdominal IVUS images were recorded and then rabbits were sacrificed.Abdominal aortas were collected and performed histochemical analysis.Results Ultrasonography revealed a significantly reduced atherosclerotic area,in abdominal aortas of rabbits infected through intima with Ad-APN,by 36.39% compared with the area in adenovirus expressing β galactosidase gene(Ad-βgal)treated rabbits(P＜0.01),and by 37.50% compared with that before treatment(P＜0.01).The lumen area stenosis was also reduced by 23.37%(P＜0.05)and 33.15%(P＜0.01),respectively.In rabbits with Ad-APN infection,the atherosclerotic plaque area as seen on Oil Red O staining was reduced significantly,by 30.70%(P＜0.05)and the greatest thickness of plaque was reduced,by 20.83%(P＜0.05)as compared with those in Ad-βgal-treated rabbits,respectively.Conclusions Intravascular ultrasound analysis is a valuable method in the in vivo study about the effects of adiponectin on the development of atherosclerosis.
