Using air cholangiography to reduce postendoscopic retrograde cholangiopancreatography cholangitis in patients with malignant hilar obstruction.

Background: Cholangitis after endoscopic retrograde cholangiopancreatography (ERCP) is a major problem for patients with hilar biliary obstruction. To date, it remains unclear whether air-contrast cholangiography (ACC) can reduce cholangitis in these patients. For this reason, our study assesses the efficacy of reducing cholangitis through ACC.

Risk factors for post-endoscopic retrograde cholangiopancreatography (ERCP) abdominal pain in patients without post-ERCP pancreatitis.

Background: Abdominal pain is often observed after endoscopic retrograde cholangiopancreatography (ERCP). Few studies have focused on the risk factors of post-ERCP abdominal pain without post-ERCP pancreatitis (PEP). This study aimed to identify risk factors of post-ERCP abdominal pain without PEP and investigate characteristics of the abdominal pain in non-PEP patients.

Ground-to-satellite quantum teleportation.

An arbitrary unknown quantum state cannot be measured precisely or replicated perfectly. However, quantum teleportation enables unknown quantum states to be transferred reliably from one object to another over long distances, without physical travelling of the object itself. Long-distance teleportation is a fundamental element of protocols such as large-scale quantum networks and distributed quantum computation.

Factors affecting occurrence of gastric varioliform lesions: A case-control study.

Aim: To investigate the factors influencing the occurrence of gastric varioliform lesions (GVLs) and their possible link with gastric cancer.

Methods: A 1:1 matched case-control study was performed to retrospectively analyze data from 1638 chronic gastritis patients who had undergone gastroscopy at one of two Chinese hospitals between 2009 and 2014. Patients with GVLs (cases) were compared to those without such lesions (controls).

Clinical and immunopathological features of patients with lupus hepatitis.

Background: Lupus hepatitis is yet to be characterized based on its clinical features and is often difficult to differentially diagnose from other liver diseases. We aimed to elucidate clinical, histopathological and immunopathological features of lupus hepatitis and to evaluate primarily the effectiveness of liver immunopathological manifestations on differential diagnosis of lupus hepatitis from other liver diseases.

Methods: A retrospective study was performed to analyze clinical features of lupus hepatitis in 47 patients out of 504 inpatients with systemic lupus erythematosus (SLE) in First Affiliated Hospital of Sun Yat-sen University, China from May 2006 to July 2009, and to evaluate the association between lupus hepatitis and SLE activity.

Deep cholestatic jaundice as the predominant manifestation in autoimmune hepatitis.

Autoimmune hepatitis is a chronic liver disease of unknown etiology. The diagnosis is based on the exclusion of other liver diseases such as drug-induced liver disease, alcohol liver disease, viral liver diseases and so on, characterizing by elevation of transaminases, hypergammaglobulinemia, auto antibodies and the histological features of interface hepatitis and plasma cells infiltration. However, deep cholestatic jaundice as the initial presentation, with elevated serum transaminases one month later, is rare in autoimmune hepatitis.
