Hypertriglyceridemic acute pancreatitis (HAP) is characterized by mitochondrial oxidative phosphorylation (OXPHOS) impairment and excessive reactive oxygen species (ROS), leading to severe inflammation and organ damage. Existing therapies often lack targeted antioxidant efficacy and long-term stability. In this study, we innovatively designed and synthesized procyanidin capsules using a one-step calcium carbonate template method, which enables sustained release of procyanidin for over one month and exhibits exceptional scavenging capacity for both ROS and RNS. The capsules demonstrated high biocompatibility in macrophage and dendritic cell lines and significantly reduced inflammatory cytokines and pancreatic damage in a HAP mouse model. Proteomic analysis revealed that the therapeutic effect is mediated through the restoration of the aqueous OXPHOS function. This work provides a novel, biocompatible, and potent antioxidant strategy for the targeted treatment of HAP.

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
