高脂血症在急性胰腺炎发病机制中的研究现状

Hypertriglyceridemia, Hypercholesterolemia, Body Mass Index, and the Risk of Acute Pancreatitis

OBJECTIVE

The purpose of this work was to check the connection between parameters of lipid profile and body mass index (BMI) in relation to the occurrence of acute pancreatitis within a sample of adults from northern China.

METHODOLOGY

A total of 123,214 participants from the Kailuan Group were incorporated into this prospective study. The subjects were categorized into quartiles on the basis of their initial levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). On the basis of BMI classification, the individuals in the study were divided into three distinct groups: normal weight, overweight, and obese. The data were analyzed to explore the correlation between lipid profile and BMI with acute pancreatitis.

RESULTS

Over a period of 12.59 ± 0.98 years, during the median follow-up duration, a total of 410 new patients with acute pancreatitis were recorded. The occurrence rate and total occurrence of acute pancreatitis demonstrated an upward trend in correlation with elevated levels of TG, TC, and BMI. Following adjustment for multiple variables, it was observed that individuals in the fourth quartile of TG and TC levels demonstrated the highest likelihood of developing acute pancreatitis. Furthermore, our analysis revealed that a proportion of 19.29% of the correlation between BMI and the likelihood of experiencing acute pancreatitis can be attributed to the influence of elevated TG levels, whereas 12.69% of the association was mediated by higher TC.

CONCLUSIONS

We found that hypertriglyceridemia, hypercholesterolemia, and obesity were risk factors for acute pancreatitis, especially in young and middle-aged men.TG and TC were the mediating factors between BMI and the risk of acute pancreatitis.

Study on the Mechanism of Probucol Nanosuspension on Hyperlipidemic Pancreatitis and Regulation of Blood Lipid Function

High-fat pancreatitis and hyperlipidemia refer to disorders of blood lipid metabolism caused by abnormally elevated blood lipids, and are risk factors for high-risk diseases such as atherosclerosis, coronary heart disease, and cerebral infarction. Hyperlipidemia is also a common disease that is common in modern people, and has a tendency to become younger. In this paper, probucol is made into a self-assembled probucol loaded nanosuspensions (SPN) using molecular selfassembly technology for research on improving its oral absorption. The main research contents include: preparation, prescription screening and characterization of physicochemical properties of SPN nanosuspensions; study of SPN intestinal cell uptake and in vivo dynamic behavior; research on the mechanism of SPN improving oral absorption of probucol and its gastrointestinal Preliminary Evaluation of Physiological Safety. And by using the method of intraperitoneal injection of SPN to interfere with the retrograde bile duct injection of SPN in the hyperlipidemia model, to make hyperlipidemia combined with severe acute pancreatitis to observe the severity of pancreatitis and lung injury; discuss the protective effect of SPN on hyperlipidemia combined with severe acute pancreatitis with lung injury and its mechanism.
