Objective To explore the influence of family factors on physical activity behavior of central obesity patient.Methods A questionnaire investigation to 182 central obesity volunteers was carried out in a residential district of shanghai on April 2007.Results The percentage of the patients taking physical activities,at least one of whose family members participate in regular exercise,was 66.7%.It was significantly higher than that (43.6%) of other patients whose family members hardly ever participated in regular exercise any more(χ2=9.260,P=0.002).The percentage of patients taking physical activities,with highly family function,was 60.2%.It was significantly higher than that of the patients in moderately dysfunctional family (49.9%) and in severely dysfunctional family(35.5%)(χ2=6.448,P=0.04).The average APGAR score,Partnership score and Growth score of the patients in taking exercise group were 7.13±2.63,1.49±0.71 and 1.35±0.73. They were significantly higher than that of the patients in taking no exercise group (6.09±3.09,1.24±0.85 and 0.90±0.86) (t=2.095～3.845,P=0.000～0.038). While family size,family economic status and marital status showed no obvious effect on physical activity behavior of central obesity patients(χ2=0.027～1.709,P＞0.05).Conclusion Highly family function and at least one of the other family members taking regular exercise can promote activity of central obesity patient in daily life.

Objective The study focused on the relationship between neopterin (NP),Gensini score and high-sensitivity C-reactive protein (hs-CRP) to explore the important role of the neopterin in patients with coronary heart disease.Methods Total of 442 patients,admitted to the Department of Cardiology at Renmin Hospital,Wuhan University from January 2012 to September 2012,were enrolled in this study.There were 176 patients in the control group and 266 patients with coroary disease in the experimental group.The Gensini score was used to assess the severity of the coronary lesions in the patients with coronary heart disease.The enzyme-linked immunosorbent assays (ELISAs) were used to measure the serum NP level.The other indicators were assessed by use of fully automatic biochemical and coagulation analyzers.The data were analyzed by using of SPSS19.0.T-test was used for analysis of the results between the control group and the experimental group.One-factor analysis variance (ANOVA) was used for comparisons of the results among the 3 groups,and Spearman correlation analysis was used for the correlation analysis between the NP level and Gensini score as well as hs-CRP level.Results The serum NP level was higher in the experimental group than that in the control group [(1.99 ± 0.37) vs (1.48 ± 0.29) ng/ml,P ＜0.05],and the NP level was positively correlated with the severity of coronary heart disease.Compared with the stable angina (SA) group,the serum NP level was significantly increased in the unstable angina (UA) group (2.00 ± 0.37) ng/ml and the acute myocardial infarction (AMI) group (2.10 ± 0.43) ng/ml (t =2.38,P ＜ 0.05).In addition,the serum NP level was positively correlated with the Gensini score (r =0.687,P＜0.001) as well as with the level of hs-CRP (r=0.190,P＜0.001).Conclusions The serum level of NP was significantly higher in patients with coronary heart disease and was positively correlated with the severity of coronary artery disease.Thus,NP may become a new indicator for the assessment of the inflammatory response in coronary atherosclerosis.
