Mitochondrial dysfunction is closely related to the occurrence and development of benign and malignant diseases of the pancreas. Mitochondrial membrane of the respiratory chain electron transfer and energy transfer plays an important role in maintaining normal cellular function. When the respiratory chain was disrupted, the oxidative stress was increased in the cell, and produced a large number of oxide intermediate products which target mitochondrial protein, DNA, etc, lead to mitochondrial dysfunction finally induced acute pancreatitis, pancreatic cancer and other diseases. In addition, mitochondrial homeostasis plays an indispensable role in maintaining the normal function of islet cells. This paper reviewed the research status of mitochondrial dysfunction in pancreatic diseases.

Alcoholic liver disease (ALD) is one of the most common chronic liver diseases worldwide and includes the different stages of steatosis, steatohepatitis, fibrosis, and liver cirrhosis. Enterococcus faecalis is a common bacterium for nosocomial infection and has a significant impact on the prognosis of patients with alcoholic hepatitis. This review mainly introduces the pathogenesis of ALD and the pathogenic mechanism of E. faecalis , summarizes the research advances in E. faecalis in ALD, and briefly describes the detection and treatment methods for E. faecalis infection in clinical practice. Since there is an extremely high mortality rate in ALD patients with lytic E. faecalis infection, an in-depth understanding of E. faecalis has become an important issue nowadays.

Hepatocellular carcinoma (HCC) is a common type of primary liver cancer with high mortality worldwide. Among the common malignant tumors in China, HCC ranks fourth in terms of incidence rate and ranks second in terms of mortality, which seriously threatens the health and life safety of the Chinese people. This article mainly introduces the dual role of Kupffer cells (KCs) in HCC and briefly describes its interaction with liver parenchymal cells and nonparenchymal cells and related targeted treatment methods. The analysis shows that in-depth research on KCs in the regulation of HCC helps to provide new ideas for further treatment of HCC.
