Aim: Omentin-1, a novel adipokine expressed in visceral adipose tissue, is negatively correlated with insulin resistance and obesity. Decreased omentin-1 expression has been found in many chronic inflammatory diseases. However, the role of omentin-1 in coronary artery disease (CAD) has not been elucidated. The aim of the present study was to determine whether serum concentration of omentin-1 was independently associated with CAD. Methods: One hundred and fifty five patients with CAD were divided into two groups: acute coronary syndrome (ACS) and stable angina pectoris (SAP). A total of 52 healthy participants served as controls. Serum concentrations of omentin-1 and interleukin-6 (IL-6) were measured using ELISA. The association of omentin-1 with CAD and cardiovascular disease risk factors was evaluated. Results: Serum omentin-1 levels were lower in patients with ACS or SAP compared with controls (ACS, 113.08±61.43 ng/mL; SAP, 155.41±66.89 ng/mL; control, 254.00±72.9 ng/mL; P<0.01). Patients with ACS also had lower serum concentrations of omentin-1 compared with patients with SAP (P<0.01). Serum concentration of omentin-1 was negatively correlated with body mass index (r=-0.17, P<0.05) and serum IL-6 concentration (r=-0.19, P<0.05). Furthermore, multiple logistic regression analysis showed that serum omentin-1 concentrations were independently correlated with CAD. Conclusion: The findings suggest that serum concentrations of omentin-1 are related to CAD.

With the whole lower esophageal and peri or para-esophageal varices, the submucosal varices, and the adventitial plexus of the cardia and fundus sufficiently obliterated by 2-OCA, this modified PTVE was more effective than EVL in the management of esophageal varices recurrence and rebleeding. Survival in these two groups was not significantly different, however.

The effect of PTVE with 2-OCA on esophageal varices is associated with the site and range of embolization. With the lower esophageal and periesophageal varices and/or the cardial submucosal and perforating vessels are sufficiently obliterated, PTVE with 2-OCA can improve long-term efficacy by preventing varices recurrence and rebleeding.

BackgroundTo summarize the experiences with the technique of percutaneous biliary stent placement for treatment of malignant biliary obstruction in patients with different types of biliary obstruction.MethodsPercutaneous biliary stent placement was performed in 126 patients with malignant biliary obstruction. The etiology included 56 cases of cholangiocarcinoma, 28 cases of pancreatic cancer, 12 cases of ampullary carcinoma, 10 cases of primary hepatic carcinoma, 8 cases of gastric cancer metastasis, 6 cases of gallbladder carcinoma, and 6 cases of liver metastasis of colon cancer. The obstructed lesion predominantly involved the common bile duct in 42 patients, common hepatic duct in 39 patients, and hilar bile duct in 45 patients. When the bile duct was punctured successfully under fluoroscopy, the guide wire was explored to across the obstruction segment under the assistant of catheter, then the stent was inserted along the super-slippery guide wire. In patients with hilar hepatic duct lesions involving both left and right hepatic ducts, the both ducts were punctured and bilateral stenting was performed. A 8.5 F internal/external drainage catheter was inserted. The liver function test and ultrasound were performed one week after the procedure to observe the decrease of bilirubin and alleviation of biliary obstruction.ResultsA total of 166 stents were implanted in 126 patients. In the 42 patients with common bile duct obstruction, each patient was implanted one stent. In the 39 patients with common hepatic duct obstruction, each patient was impanted one stent. In the 45 patients with hilur bile duct obstruction, 38 patients were placed 2 stents, one patient was placed with 3 stents, and the rest were placed with one stent. The serum total bilirubin decreased from 309.2 ± 158.3 µmol/L before the procedure to148.5 ± 98.0 µmol/L one week after the procedure (P < 0.001). Alkaline phosphatase and alanine aminotransferase significantly decreased (P < 0.001). Five cases died within 1 month (4%) after the procedure. Complications occurred in 9 cases (7.1%). Six patients underwent combined duodenal self-expandable metal stent placement successfully.ConclusionsThe percutaneous biliary stent placement is a safe and effective palliative therapy for malignant biliary obstruction by improving liver function and 1ife quality.
