AIM To investigate the prevalence and causes of cholestasis in patients with inflammatory bowel diseases in the Swiss Inflammatory Bowel Diseases Cohort. METHODS A retrospective cohort study was performed of all the patients in the Swiss Inflammatory bowel disease Cohort. Total bile acid was measured for all patients and cholestasis was defined as a concentration > 8 μmol/l. The characteristics of patients with or without cholestasis were compared. Bile acid profiles were then determined for 80 patients with high total bile acid and 80 matched patients with low total bile acid. Bile acid profiles were compared for smokers vs nonsmokers, ileal vs colonic disease, and inflammatory vs non inflammatory *** Ninety-six patients had more than 8 μmol/l total bile acid, giving a prevalence of 7.15%. Patients with an obvious cause of cholestasis, such as primary sclerosing cholangitis, were then excluded, leaving 1190 participants with total bile acid l/l and 80 with total bile acid > 8 μmol/l. In multivariate analysis, calcium supplementation was significantly associated with cholestasis(odds ratio, 2.36, 95%CI: 1.00-5.21, P = 0.040) whereas current smoking significantly reduced the risk of cholestasis(odds ratio, 0.42, 95%CI: 0.17-0.91, P = 0.041). levels of all conjugated bile acids were higher in the cholestasis group than in the control group. When we compared patients with ileal vs colonic disease, the former had higher levels of primary, secondary, and tertiary bile acids whereas patients with colonic disease had higher levels of conjugated bile *** Prevalence of cholestasis is high. Smoking appears to reduce cholestasis. Conjugated bile acids are higher in cholestasis and in colonic disease whereas unconjugated in ileal disease.

Percutaneous endoscopic colostomy （PEC） is increasingly proposed as an alternative to surgery to treat various disorders, including acute colonic pseudo-obstruction, chronic intestinal pseudo-obstruction and relapsing sigmoid volvulus. We report on a severe complication that occurred two months after PEC placement. A 74-year-old man with a history of chronic intestinal pseudo-obstruction evolving since 8 years was readmitted to our hospital and received PEC to provide long-standing relief. The procedure was uneventful and greatly improved the patient＇s quality of life. Two months later, the patient developed acute stercoral peritonitis. At laparotomy, the colostomy flange was embedded in the abdominal wall but no pressure necrosis was found at the level of the colonic wall. This complication was likely related to inadvertent traction of the colostomy tube. Subtotal colectomy with terminal ileostomy was performed. We review the major features of 60 cases of PEC reported to date, including indications and complications.

Market-oriented housing reforms and the rapid urbanization process have led to spectacular growth in the Chinese real estate sector(RES).However,the changes in the role played by this sector in the structural dynamics of the Chinese economy have not been examined ***,we analyze the intersectoral structural changes to the Chinese RES,its linkages with the rest of the economy,and its growth sources,using four Chinese input-output tables from 2002 to *** depart from existing work on the RES by using the causative matrix approach and structural decomposition analysis,and obtain three main ***,the RES,which received little non-RES feedback during the 2002-2007period,has subsequently received much more substantial ***,the impact of the RES on China s economic growth stems mainly from its forward ***,the growth in the RES has been driven mainly by domestic demand *** results highlight that the Chinese RES,which plays a key role in value chains,is highly dependent on its own final demand and a fall in its demand would impede economic *** important implication of these results is that developing the national economy by stimulating the RES would not be as effective as developing the RES through stimulating the national economy.

Direct laser Sintering (DSl), a technology enabling the production of dense metal components directly from 3D CAD data, was used for the first time to produce a Metal Matrix Composite (MMCp) based on Al-Si-Cu alloy in view of its application in different fields, in particular for aeronautics. The porosity of the material obtained so was investigated by using optical and electron microscopy and, in particular, X-ray computed microtomography techniques. DSl is a unique technique to produce complex components in an economical way while computed microtomography is a unique technique to evaluate the porosity and pore and cracks distribution in a not destructive way. A near homogeneous distribution of the porosity and pore sizes was observed both comparing different regions of the same specimen and also by comparing different samples obtained by using the same DlS production method. A quantitative analysis of the damage in the composite is also reported.
