New advances in the treatment of pancreatic cancer by targeting tumor microenvironment / 临床肝胆病杂志

Pancreatic cancer is the malignant tumor of the digestive tract with the lowest 5-year survival rate, and current first-line treatment regimens cannot significantly improve the overall prognosis of patients, so it is necessary to explore new treatment methods. A large number of studies have shown that the tumor microenvironment of pancreatic cancer, such as stromal barrier, immune microenvironment, and exosomes, plays an important role in promoting the proliferation, invasion, metastasis, and chemoradiotherapy resistance of pancreatic cancer cells. This article summarizes the potential targets associated with the tumor microenvironment of pancreatic cancer and related clinical research advances, in order to provide new ideas for the treatment of pancreatic cancer.

Mechanism of ferroptosis and its role in liver diseases / 临床肝胆病杂志

Ferroptosis is a newly discovered regulatory cell death induced by the accumulation of iron-dependent lipid peroxides, with the morphological manifestations of decreased mitochondrial volume, increased mitochondrial membrane density, and reduction or disappearance of mitochondria. The mechanism of ferroptosis is mainly associated with disturbance of iron metabolism, imbalance of amino acid antioxidant system, and accumulation of lipid peroxides. Studies have shown that ferroptosis plays different roles in different liver diseases, and ferroptosis can participate in the progression of various liver inflammatory diseases and inhibit the formation of liver fibrosis, the development of hepatocellular carcinoma, and sorafenib resistance. This article summarizes the advances in the mechanism of ferroptosis and its role in liver diseases, so as to provide a reference for further research and treatment of liver diseases.

Advances in research on alcoholic liver disease complicated with sepsis / 中华全科医师杂志

Alcoholic liver disease is often complicated with sepsis at the end stage of the disease, inducing acute-on-chronic liver failure and multiple organ and system injuries, with high short-term mortality. At present, there is still a lack of effective methods for early diagnosis and prognosis, and measures for prevention and treatment in alcoholic liver disease complicated with sepsis. This article reviews the research progress of alcoholic liver disease complicated with sepsis to provide reference for clinical practice.
