Objective To determine the level of adiponectin (APN) in serum and induced sputum of patients with chronic obstructive pulmonary disease both during acute exacerbation (AECOPD) and silent stage, and investigate APN' s role as a marker of inflammation in the pathogenesis of COPD. Method From October 2008 to October 2009,30 male AECOPD patients in the emergency department, 30 male silent COPD patients in the department of respiratory diseases and 30 healthy nonsmoking male volunteers were included. All subjects' serum and induced sputum were collected, and they were all of normal weight(BMI range of 18.5～ 24.9 kg/m2). Patients were excluded if they suffered from severe bronchial asthma, bronchiectasis or autoimmune disease. The number of cells in induced sputum was counted and the cell type was classified. The concentrations of APN, IL-8, IL-6 and TNF-α in both serum and sputum were measured by using ELISA, and their pulmonary function was tested. The different groups were compared among them by using the t -tests, ANOVA analysis or nonparametric analysis, the relation between variables was assessed by using the Pearson or Spearman correlation test. Results The concentrations of APN in both serum and induced sputum of AECOPD patients were significantly higher than those in the silent COPD patients and the control subjects ( P ＜ 0.01 ). The concentrations of APN in the silent COPD patients were significantly higher than those in the control subjects ( P ＜ 0. 01 ). There were significant relationships between the concentrations of APN in serum and induced sputum and the levels of IL-8 and TNF-α in AECOPD patients ( r = 0.739, 0. 734,0.852 and 0. 857, respectively, P ＜ 0. 05) and in silent COPD patients ( r = 0.751,0.659, 0.707 and 0.867, respectively, P ＜0.05). There was significant relation betweenship between APN and neutrophil in induced sputum of AECOPD patients (r = 0.439, P ＜ 0.05). Conclusions APN was involved in the process of systemic and airway inflammation of COPD, and it was related with IL-8 and TNF-α. APN can be used as a new inflammation marker for COPD.

Objective: To explore the progression rate of cortid maximal plaque area and the risk of new ischemic cardiovascular disease (ICVD) in a rural cohort in Beijing.
Methods: The PRC-USA collaborative study had been regularly conducted in Shijingshan area in Beijing. The carotid ultrasound examination, ICVD risk factor and acute cardiovascular events follow-up were conducted in those participants. A total of 1479 subjects who received at least 2 carotid ultrasound examinations and had no cardiovascular disease before the second ultrasound were studied. They were divided into 5 groups:①Control group, the participants had no plaque detected by 2 ultrasounds; ② New plaque group, new plaque was found at the second ultrasound examination; ③ Plaque regression group; ④ Plaque stabilized group and ⑤ Plaque progression group. The hazard ratio (HR) between the progression rate of corotid maximal plaque area and new ICVD events was estimated by Cox proportional hazard regression analysis .
Results: Compared with Control group, the HR for new ICVD events were higher in groups②,③,④and⑤at 3.5, 5.7, 6.2 and 7.3 respectively, all P<0.05. The increasing trend of HRs remained signiifcant with the adjusted age and gender, P<0.001.
Conclusion: The progression rate of maximal corot id plaque area rate could predict the risk of new ICVD events in clinical practice.
