Objective To investigate the role of deferoxamine pretreatment for hepatic ischemia reperfusion injury in liver auto-transplantation in rats. Method Murine liver auto-transplantation model was established. Ninety six male Sprague-Dawley rats were randomly divided into three groups: 32 rats in deferoxamine pretreatment group (D), 32 rats in control group with aqua pro injection pretreatment(C) and 32 rats in sham-operation group (S). The animals were killed at 30 min, 2 h, 6 h, 24 h after operation respectively. ALT and AST level, superoxide dismutase (SOD) and malondialdehyde (MDA), liver histological change(HE), the protein expression of HIF-1α、TNF-α and IL-1 were measured. Results At 30 min, 2 h, 6 h, 24 h after operation, the levels of ALT,AST,MDA and the expression of IL-1 protein and TNF-α protein were higher in group C than group D significantly,while the expression of HIF-1α and SOD were higher in group D [SOD(411±70; 384±53; 379±46)、H1F-1α(0.0413±0.0040; 0.0684± 0.0032; 0.0583±0.0032; 0.0491±0.0026)] than group C significantly (P<0.01) [SOD(341±21; 323±25; 303±25)、HIF-1α (0.0254±0.0024; 0.0312±0.0022; 0.0381±0.0022; 0.0257± 0.0015)] (F>59.881;P<0.01). Conclusion The up-regulated expression of HIF-1α, decreased liver lipid peroxidation injury and TNF-α and IL-1 levels, may be involved in the mechanism hy which deferoxamine pretreatment protects liver from ischemia reperfusion injury in rats' liver auto-transplantation.

Objective:To summarize our experience in diagnosis and treatment of Budd-Chiari syndrome(BCS) accompanied with hepatic nodules.Methods:The clinical data of 33 patients with BCS accompanied with hepatic nodules who were treated at Henan Provincial People's Hospital from January 2012 to December 2018 were retrospectively analysed. A total of 33 patients were enrolled, including 17 males and 16 females, with an average age of 51 years. Analyze the treatment and prognosis of different types of nodules.Results:Of 33 patients, 27 were diagnosed to have hepatocellular carcinoma and 6 benign proliferative nodules. Treatment of patients with hepatocellular carcinoma included, transcatheter arterial chemoembolization ( n=1) and hepatectomy ( n=26). The survival time of these patients with hepatocellular carcinoma ranged from 10.0 to 78.0 months (mean 37.8 months). For the remaining 6 patients with benign nodules, the nodules were multiple and no malignant changes were observed on follow-up. Conclusion:For patients with BCS associated with benign nodules, no specific treatment was required. Hepatocellular carcinoma assocated with BCS had good prognosis. An aggressive surgical resectional approach is recommended to treat and to relieve the hepatic outflow obstruction.
