PG - 4344-4353 LID - 10.1007/s10620-020-06801-6 [doi] AB - BACKGROUND: Acute lung injury (ALI) is the most common complication and one of the leading causes of mortality of severe acute pancreatitis (SAP). Nevertheless, no effective therapeutic schemes are presently available. AIMS: To investigate the effect and potential mechanism of mesenteric lymph duct ligation (MLDL) on experimental SAP-induced ALI. METHODS: Immediately following MLDL, rats were subjected to SAP by retrograde injection of 5% sodium taurocholate into the biliopancreatic duct. At 24 h after modeling, tissues were collected for morphological examination. The levels of TNF-alpha, IL-6, intercellular adhesion molecule-1 (ICAM1), diamine oxidase (DAO), and D-lactic acid (D-LA) in serum, and the myeloperoxidase (MPO) activity in lung tissues were determined. Moreover, the expressions of high mobility group box 1 (HMGB1), receptor of advanced glycation endproducts (RAGE), and NF-kappaB p65 at the mRNA and protein levels in lung tissues, and the expressions of HMGB1, RAGE, and TNF-alpha at the mRNA level in intestinal lymphoid tissues were evaluated. RESULTS: MLDL significantly attenuated the histological injury of the pancreas and lung and reduced the production of TNF-alpha, IL-6, and ICAM1. Besides, MLDL repressed the activity of MPO in the lung. However, the levels of serum DAO and D-LA were decreased without obvious morphological improvement in intestinal injury. Moreover, MLDL apparently reduced the up-regulation of HMGB1, RAGE, and NF-kappaB p65 in lung tissues, as well as the expressions of HMGB1, RAGE, and TNF-alpha in intestinal lymphoid tissues. CONCLUSIONS: Mesenteric lymph was a source of harmful factors leading to SAP-ALI. MLDL could alleviate SAP-ALI probably by inhibiting HMGB1-induced production of inflammation factors. CI - (c) 2021.
