Objective:To study the factors influencing repeatedly hospitalization in patients with acute pancreatitis (AP), and to analyse the predictive value of triglyceride for repeated hospitalization.Methods:The clinical data of 1 958 patients with AP treated at the First Affiliated Hospital of Anhui University of Science and Technology from January 2012 to April 2022 were analyzed. Of 1 733 AP patients who were enrolled, there were 1 000 males and 733 females, with mean ± s. d age being (49.4±16.4) years. Patients were grouped based on their ID numbers to determine their number(s) of hospitalization. Those who were admitted only once were included in the initial hospitalization group ( n=1 030), and those who were admitted twice or more were included in the repeated hospitalization group ( n=703). The factors influencing repeated hospitalization were analyzed by univariate analysis and multivariate logistic regression analysis. The predictive value of triglyceride for repeated hospitalization was evaluated by receiver operating characteristic (ROC) curve. Results:Multivariate logistic regression analysis showed that hypertriglyceridemia ( OR=1.445, 95% CI: 1.144-1.825, P=0.002) and biliary causes ( OR=3.184, 95% CI: 1.978-5.125, P<0.001) were independent risk factors for repeated hospitalization. When triglyceride <10.9 mmol/L, the prediction of AP patients without repeated hospitalization was 90.6%. The area under the ROC curve was 0.589, and the Yoden index was 0.170. Conclusion:Hypertriglyceridemia was risk factor for repeat hospitalization in AP patients and the efficacy of triglyceride in predicting repeat hospitalization in AP patients was good.

Pathological vascular remodeling is a hallmark of various vascular diseases. Previous research has established the significance of andrographolide in maintaining gastric vascular homeostasis and its pivotal role in modulating endothelial barrier dysfunction, which leads to pathological vascular remodeling. Potassium dehydroandrographolide succinate (PDA), a derivative of andrographolide, has been clinically utilized in the treatment of inflammatory diseases precipitated by viral infections. This study investigates the potential of PDA in regulating pathological vascular remodeling. The effect of PDA on vascular remodeling was assessed through the complete ligation of the carotid artery in C57BL/6 mice. Experimental approaches, including rat aortic primary smooth muscle cell culture, flow cytometry, bromodeoxyuridine (BrdU) incorporation assay, Boyden chamber cell migration assay, spheroid sprouting assay, and Matrigel-based tube formation assay, were employed to evaluate the influence of PDA on the proliferation and motility of smooth muscle cells (SMCs). Molecular docking simulations and co-immunoprecipitation assays were conducted to examine protein interactions. The results revealed that PDA exacerbates vascular injury-induced pathological remodeling, as evidenced by enhanced neointima formation. PDA treatment significantly increased the proliferation and migration of SMCs. Further mechanistic studies disclosed that PDA upregulated myeloid differentiation factor 88 (MyD88) expression in SMCs and interacted with T-cadherin (CDH13). This interaction augmented proliferation, migration, and extracellular matrix deposition, culminating in pathological vascular remodeling. Our findings underscore the critical role of PDA in the regulation of pathological vascular remodeling, mediated through the MyD88/CDH13 signaling pathway.
