Exfoliative cytology of bile aspirated from percutaneously placed combined external/internal biliary drainage catheters yielded positive results in 34% of 100 cases. There were no false-positive results. Bile cytology is a simple, inexpensive, and useful method which can establish a diagnosis of malignant biliary obstruction after catheter decompression.

Hepatic stellate cells (HSCs) are the central link of the occurrence and development of hepatic fibrosis, and autophagy promotes HSCs activation. N6-methyladenosine (m6A) RNA modification can also control autophagy by targeting selected autophagy-associated genes. but up to now, little research has been done on the m6A modification autophagy-related genes (ATGs) in hepatic fibrosis.

Background: Cholangiocarcinoma is a challenging malignancy with limited responses to conventional therapies, particularly immune checkpoint inhibitor therapy. Tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLSs) are key components of the tumor microenvironment (TME) and have been implicated in the immune response to cancer. However, the role and difference of TLSs and TILs in patients with cholangiocarcinoma remains unclear.

Cell models emulating an in vitro parasitic infection can greatly improve our understanding of helminthiases. Nonetheless, it remains challenging to select an appropriate in vitro model to study molecular pathogenesis of infections by trematodes having a complex life cycle. Therefore, adequate models are in high demand.

Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse perinatal outcomes, yet the correlation between ICP and the neutrophil-to-lymphocyte ratio (NLR) remains unclear. This study aims to investigate the diagnostic value of NLR in ICP. In this retrospective case-control study, 113 patients with ICP treated in Beilun District People's Hospital from January 2020 to December 2022 were recruited and categorized as the ICP group, and 209 healthy pregnant women treated during the same period were selected as the control group.

Vascular inflammation regulates endothelial pathophenotypes, particularly in pulmonary arterial hypertension (PAH). Dysregulated lysosomal activity and cholesterol metabolism activate pathogenic inflammation, but their relevance to PAH is unclear. Nuclear receptor coactivator 7 () deficiency in endothelium produced an oxysterol and bile acid signature through lysosomal dysregulation, promoting endothelial pathophenotypes.
