Cholangiocarcinoma is a malignant tumor originating from the epithelial cells of the bile duct, and its incidence and mortality rates keep increasing year by year. Unknown pathogenesis of this disease has led to the difficulties in early diagnosis and treatment. With the development of genetic engineering and bioinformatics, more and more studies have found that long non-coding RNA (lncRNA) is closely associated with the pathophysiological process of cholangiocarcinoma. This article summarizes the research advances in the role of lncRNA in mediating the biological behaviors of cell proliferation, apoptosis, metastasis, invasion, epithelial-mesenchymal transition, and drug resistance in cholangiocarcinoma, as well as the association of lncRNA with clinical features and prognosis.

Hepatic ischemia-reperfusion injury is one of the most important factors affecting the prognosis of clinical hepatic surgery. Studies have shown that microRNAs can participate in the process of hepatic ischemia-reperfusion injury through multiple pathways. This article reviews the biosynthesis and function of microRNAs and the mechanisms of action of microRNAs in the regulation of hepatic ischemia-reperfusion injury through energy metabolism, apoptosis, autophagy, oxidative stress, and cellular inflammation. It is pointed out that the treatment targeting microRNAs has a promising future in the treatment of hepatic ischemia-reperfusion injury, and further studies are needed in the future.
