Effect of Silver Dopants on the ZnO Thin Films Prepared by a Radio Frequency Magnetron Co-Sputtering System.

Ag-ZnO co-sputtered films at various atomic ratios of Ag (Ag/(Ag + Zn) at.%) were prepared by a radio frequency magnetron cosputtering system, using the co-sputtered targets of Ag and ZnO. The activation of the Ag acceptors (Ag) and the formation of the Ag aggregations (Ag⁰) in the ZnO matrix were investigated from XRD, Raman scattering, and XPS measurements.

Application of dsRNA in cancer immunotherapy: current status and future trends.

Cancer cells create a microenvironment that prevents tumor rejection by the host's immune system. The activation of pattern recognition receptors (PRRs) can elicit an innate immune response and guide the adaptive immune response to overcome this. dsRNA analogs can trigger TLR3, RIG-I, MDA5, NLRP3 and several other PRRs to induce not only robust immune response against cancer but also programmed cell death.

Antiviral therapy delays esophageal variceal bleeding in hepatitis B virus-related cirrhosis.

Aim: To investigate the effect of antiviral therapy with nucleoside analogs in hepatitis B virus (HBV)-related cirrhosis and esophageal varices.

Methods: Eligible patients with HBV-related cirrhosis and esophageal varices who consulted two tertiary hospitals in Beijing, China, the Chinese Second Artillery General Hospital and Chinese PLA General Hospital, were enrolled in the study from January 2005 to December 2009. Of 117 patients, 79 received treatment with different nucleoside analogs and 38 served as controls.

Low incidence of complications from endoscopic gastric variceal obturation with butyl cyanoacrylate.

Background & Aims: Endoscopic variceal obturation with tissue adhesive is used to control gastric variceal bleeding. We investigated the prevalence of serious complications from this therapy.

Methods: We performed a retrospective analysis of complications that occurred in 753 patients with gastric variceal hemorrhages who were hospitalized in 2 tertiary referral hospitals.

Study of glue extrusion after endoscopic N-butyl-2-cyanoacrylate injection on gastric variceal bleeding.

Aim: To investigate glue extrusion after endoscopic N-butyl-2-cyanoacrylate injection on gastric variceal bleeding and to evaluate the long-term efficacy and safety of this therapy.

Methods: A total of 148 cirrhotic patients in our hospital with esophagogastric variceal bleeding (EGVB) were included in this study. N-butyl-2-cyanoacrylate was mixed with lipiodol in a 1:1 ratio and injected as a bolus of 1-3 mL according to variceal size.

[Intestinal intraepithelial lymphocytes in cirrhosis: experiment with rats].

Objective: To investigate the phenotypes of T lymphocytes in the intestinal epithelium in cirrhosis.

Methods: Forty Wistar rats were randomly divided into 2 groups: cirrhosis group (n = 25) undergoing subcutaneous injection of 40% carbon tetrachloride twice a week for 10-12 weeks to establish cirrhosis models, and control group (n = 15). Twelve weeks later the rats were killed with their levers taken out.

Treatment of gastric varices by endoscopic sclerotherapy using butyl cyanoacrylate: 10 years' experience of 635 cases.

Background: Gastric varices (GV) are life-threatening for patients with portal hypertension. Endoscopic injection with butyl cyanoacrylate (BC), the mainstay of the therapy for GV, has been reported to be effective for hemostasis of bleeding varices, but its efficacy in the obliteration of GV and impact on the survival of patients still needs clarification. Here we summarized our experience of 10 years' practice to evaluate the efficacy and safety of endoscopic therapy using BC for GV patients.

Pancreatic encephalopathy and Wernicke encephalopathy in association with acute pancreatitis: a clinical study.

Aim: To investigate clinical characteristics and therapy of pancreatic encephalopathy (PE) and Wernicke encephalopathy (WE).

Methods: In a retrospective study of 596 patients with acute pancreatitis (AP), patients with PE were compared to those with WE in regards to history, clinical manifestation, diagnosis, treatment and outcome.

Results: There were 93 patients with severe acute pancreatitis (SAP).

Histopathological study of vascular changes after intra-arterial and intravenous injection of N-butyl-2-cyanoacrylate.

Objective: To assess the histopathological vascular changes after injection of N-butyl-2-cyanoacrylate into the vessels of adult rabbits.

Methods: The animals used were 42 pure-blood New Zealand white rabbits weighing 2-3 kg. 0.

Reversibility of experimental rabbit liver cirrhosis by portal collagenase administration.

The regression of cirrhosis is associated with increased intrahepatic collagenolytic enzyme activity. We investigated whether collagenase supplementation via portal vein infusion can retard cirrhosis development and/or reverse cirrhosis. In all, 35 rabbits were initially assigned to study.

Intraductal ultrasonography and endoscopic retrograde cholangiography in diagnosis of extrahepatic bile duct stones: a comparative study.

Background: Intraductal ultrasonography (IDUS) is highly accurate in detection of extrahepatic bile duct stones. This study was to compare the accuracy of IDUS and endoscopic retrograde cholangiography (ERC) in the diagnosis of extrahepatic bile duct stones.

Methods: Thirty patients suspected of extrahepatic bile duct stones on B ultrasonography, CT, or MRI were enrolled for study.
