Objective To evaluate endoscopic retrograde cholangiopancreatography (ERCP) for diagnosis and management of biliary cast syndrome after orthotropic liver transplantation. Methods A total of 71 consecutive patients with abnormal liver function and MRCP findings after liver transplantation underwent ERCP for diagnosis and management. Their data were retrospectively reviewed. Results A total of 188 sessions of ERCP were carried out on the 71 patients, most of whom were found to have stenosis of anastomotic stoma and/or bile duct. Bile sludge was found and removed in all patients diagnosed within 3 months after liver transplantation, while pigmentoid stones were found and removed in patients diagnosed within 3-6 months and biliary casts in patients diagnosed at more than 6 months. Each patient underwent 2.6 sessions averagely. Biliary casts were formed at an average time of 22. 7 ± 15.6 months after transplantation. PostERCP complications included 2 cases of pancreatitis and 3 cholangitis, with an occurrence rate of 2. 6%(5/188), which were all controlled with conservative treatment. The follow-up data was available in 56 patients showing improvement in liver function after ERCP, among who 42 met the endoscopic criteria of cure,1 0 received second liver transplantation because of progressive sclerosing cholangitis and 4 died from diseases other than liver transplantation. Conclusion Therapeutic ERCP for the biliary cast syndrome after liver transplantation is feasible, safe and effective, and can be performed repeatedly with good short-term effect.

Objective To investigate human plasma glycoproteomie changes related to human immunodeficiency virus (HIV) infection,and to identify glycoproteins with potential anti-HIV activity or anti-HIV drug targets. Methods Plasma proteins with lower abundance were enriched through affinity purification to remove albumin and IgG in clinical samples (HIV-positive patient, n= 10, and healthy controls, n= 20). Proteins were separated by two-dimensional electrophoresis (2-DE) and stained by Pro-Q emerald glycoprotein stain kits. The 2-DE image was analyzed by ImageMaster software to find differential glycoproteins. Furthermore, the depleted HIV-positive and healthy control plasma proteins were digested by PNGase F. Glycoproteins were deglycoliszed, separated by 2-DE and analyzed by ImageMaster software. Differential glycoproteins were identified by liquid chromatography combined with high capacity ion trap mass spectrometry (HCT). Results The pretreatment of HIV-positive plasma prior to 2-DE could efficiently remove the high aboundant albumin and IgG in plasma and improve the detection of proteins with low-abundance. High revolution 2-DE gel images of glycoproteins from HIV positive and healthy control plasma samples were obtained. Glycoproteins were successfully deglycolized through PNGase F treatment. Thirteen differential glycoproteins were identified by liquid chromatography combined with mass spectrometry. These proteins included alphalantitrypsin precursor and serine/threonine-protein kinase N1. Conclusions Potential HIV infection related proteins,such as alphal-antitrypsin precursor are successfully identified. Our study may offer some help to understand the molecular mechanism of HIV infection and select new drug targets for preventing HIV infection.
