Background: Obesity is a common public health issue and is currently deemed a disease. Research has shown that the risk of gallstones in individuals with obesity is elevated. This study aimed to explore the bile proteomics differences between cholelithiasis patients with obesity and normal body weight. Methods: Bile samples from 20 patients(10 with obesity and 10 with normal body weight) who underwent laparoscopic cholecystectomy at our center were subjected to tandem mass tag labeling(TMT) and liquid chromatography-tandem mass spectrometry(LC-MS/MS), followed by further bioinformatic analysis. Results: Among the differentially expressed proteins, 23 were upregulated and 67 were downregulated. Bioinformatic analysis indicated that these differentially expressed proteins were mainly involved in cell development, inflammatory responses, glycerolipid metabolic processes, and protein activation cascades. In addition, the activity of the peroxisome proliferator-activated receptor(PPAR, a subfamily of nuclear receptors) signaling pathway was decreased in the Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis. Two downregulated proteins in the PPAR signaling pathway, APO A-Ⅰ and APO A-Ⅱ, were confirmed using enzyme-linked immunosorbent assay. Conclusions: The PPAR signaling pathway may play a crucial role in the development of cholelithiasis among patients with obesity. Furthermore, biliary proteomics profiling of gallstones patients with obesity is revealed, providing a reference for future research.

Factors influencing survival of patient with in-hospital ventricular fibrillation： experience of a single center

Journal of Geriatric Cardiology 2010年第1期7卷 21-24页

作者： Jing Wang jiang-min Chu Wei hua Fang-Zheng Wang Ke-Ping Chen Qiao Qing Hong-Xia Niu Shu Zhang Clinic EP Lab and Arrhythmia Center Cardiovascular Institute and Fu Wai Hospital Chinese Academy of Medical Science and PekingUnion Medical College Beijing 100037 China

Objective To evaluate the factors influencing the outcome of patients who suffered in-hospital ventricular fibrillation （IHVF）. Methods Data of patients with IHVF in a single center were collected. Clinical characteristics of patients were compared between those survived （n=112） and those died （n=94）, and those with IHVF occurred in inpatient ward and in emergency center. Multiple logistic regression analysis was used to identify factors associated with survival. Results There were 206 events in the analysis. The most common underlying disease was coronary artery disease （CAD）, especially acute myocardial infarction （AMI）. On multiple logistic regression analysis, independent predictors for failure to survive were higher NYHA class （odds ratio 1.7, 95% CI, 1.3-2.2, P〈 0.001）, lower serum potassium concentration （ [K＋] ）（odds ratio, 2.9, 95% CI, 1.9-4.3, P--0.007） and adrenaline usage （odds ratio, 25, 95% CI 11.5-55.1, P〈 0.001）. Emergency group have better NYHA class （P = 0.012）, lower [K-] （P 〈 0.001） than in inpatient ward group. Hypokalemia （serum potassium level 〈4.5 mmol/L） was found in all patients with AMI in emergency group. In AMI sub-group, 56.9% of IHVF events occurred within the first day after AMI, and decreasing within 2 weeks. Patients with fight coronary artery as infarction related artery （IRA） oRen （8/9, 88.9~,5） had bmdycardia （R-R interval 〉 ls） before the occurrence of IHVF, while those with left anterior descending artery as IRA often showed tachycardia （R-R interval 〈 0.6s）（8/12, 66.7%）. Conclusion The most common disease causing IHVF is CAD. Keeping [K＋] above 4.5mmol/1 could prevent on-setting IHVF, especially to AMI patients. The worse heart function is associated with higher rate of IHVF and worse pmgnosis （J Geriatr Cardio12010; 7：21-24）.
