ABSTRACT
Objective To explore the relationship between serum uric acid(SUA) levels and metabolic syndrome(MS) in middle-aged and elderly people,and to investigate the impacts of age and gender on the relationship between SUA and MS.Methods A cross-sectional study was carried out in general population aged over 35 years in rural area of Yiling District,Yichang City in 2007.All subjects were investigated by using the standardized questionnaire,physical and biochemical examinations.MS was defined according to the diagnostic criteria of the latest Chinese guidelines.All subjects were divided into different subgroups based on quartiles of SUA levels and age(35-44 years old,45-59 years old,over 60 years old).The relationship of MS with age and SUA levels were investigated.Results 9354 subjects consisted of 3883 males and 5471 females were included in this study.The percentage of subjects aged over 60 years was 21.1％ in men and 17.4％ in women.The prevalence of MS from the first quartile to the fourth quartile were 3.8％,5.5％,7.9％,15.2％ in males,and 3.1％,5.5％,7.9％,16.7％ in females,respectively.The SUA levels was positively correlated with MS in both sexes after adjusting for other confounding factors.By analyzing associated-subgroups based on age and SUA levels,logistic regression analysis showed that the risk of MS was significantly increased with aging and SUA levels in female subjects.The association between age and MS was significantly weaker in men than in women.Conclusions There is a positive correlation between SUA levels and MS.The associations of MS with age and SUA levels are more closely in women than in men.The risk of MS may be highest in middle-aged and elderly women with high level of SUA.
ABSTRACT
Objective To investigate the features,prevention and treatment of complications of ultrasound-guided hepatic puncture biopsy.Methods One hundred and seventy-five cases underwent ultrasound-guided hepatic puncture biopsy were retrospectively analyzed.Results The incidence of complications was 16 cases (9.1%),including 5 cases with vasovagal episodes(2.9%),4 cases with ache which needed medicine treatment (2.2%),3 cases with hemorrhage in liver capsule(1.7%),3 cases with hypoglycemia(1.7%),1 case with serve hemorrhage in abdominal cavity(0.6%).Hemorrhage limited in liver capsule,vasovagal episodes,hypoglycemia and ache were relieved with corresponding treatments.One case with hemorrhage in abdominal cavity was handled with percutaneous microwave ablation therapy guided by contrast-enhanced ultrasound.Conclusions Ultrasound-guided hepatic puncture biopsy has good value and low complication.The most severe complication is hemorrhage,which can be handled with percutaneous microwave ablation therapy guided by contrast-enhanced ultrasound.
