Severe acute pancreatitis is the systemic inflammatory reaction caused by the preternatural activation of trypsogen. The necrotizing pancrea as the antigen or stimulant, activiates immunocyte and in-flammatory cell to release a great deal of cytokines, including proinflammatery factor and anti-inflammatory factor. The former aggravates the damage of constitution, the latter could antigonize the damage of anti-inflam-matory factor. The unbalance of pro-and anti-inflammatory cytokines ,leads to the occurrence of systemic in-flammatory syndrome, even the mutiple organ failure.

Objective To summerize our experience in the diagnosis and treatment of pancreatic cystic neoplasms.Methods A retrospective analysis was conducted on the clinical data of 126 patients with pancreatic cystic neoplasms seen between January 2003 and December 2012 in the Fuzhou General Hospital.Results There was no special clinical manifestation in this series of 126 patients with pancreatic cystic neoplasms.The diagnostic accuracies of ultrasound,CT and MRI were 90.8％ (109/120),93.4％ (114/122) and 96.3％ (103/107) respectively.Eighteen and ten patients were observed to have elevated serum CA19 9 and CEA respectively.One hundred and five patients received conventional open surgery,while 21 patients underwent laparoscopic operations.The operations in cluded enucleation of tumor (n=11),pancreatic segment resection (n=5),spleen preserving distal pancreatectomy (n=30),distal pancreatectomy (n=26),duodenum-preserving pancreatic head resection (n=4),pylorus-preserving Whipple resection (n=5),Whipple procedure (n=38),total pancre atectomy (n=2) and exploratory laparotomy and biopsy (n=5).The perioperative mortality rate was 0.8％ (1/126).Pancreatic fistula (B and C) occurred in 16 patients (12.7％,16/126),and postoperative hemorrhage (B and C) occurred in 9 patients (7.1％,9/126).One hundred and fourteen patients were followed up from 6 to 72 months (median 52.4 months).The five-year survival rates for all the pancreatic cystic neoplasms,non-invasive and invasive neoplasms were 80.5％,96.4％ and 40.7％ respectively.Conclusions Pancreatic cystic neoplasms are a rare subset of pancreatic tumor,being increasingly detected due to the widespread use of abdominal imaging and improved imaging techniques.Most of them are benign,but some are malignant or they have malignant transformation and metastatic potential.Patients with asymptomatic benign pancreatic cystic neoplasms,especially small size,are candidates for observation.Patients with clinical symptoms or having a high suspicion of malignancy should be offered surgical resection.Non-invasive neoplasms should receive pancreatic preserving operations.Pancreatectomy plus regional lymph nodes dissection with or without combined resection of adjacent multi organs should be adopted for invasive neoplasms.

Objective To study the anatomy of the caudate lobe and to apply the knowledge in caudate lobe resection and piggyback liver transplantation. Methods Dissection of the caudate lobe was carried out in 35 fresh adult livers. Before dissection, the portal venous system was injected with barium sulfate emulsion to show the portal branches of the caudate lobe. Results The caudate lobe was shown to consiste of 3 portions: (1) the Spigelian lobe, the paracaval portion and the caudate process. The Spigelian lobe was pyramidal in shape with 3 faces, a peak and a base; (2) the paracaval portion was situated to the right and to the front of the vena cava; (3) the caudal process was the liver parenchyma between the hepatic hilum and the anterior aspect of the vena cava. Conclusions The entire caudate lobe is situated at the posterior part of the liver and it surrounds the vena cava. The key point in resecting the entire caudate lobe or in performing a piggyback liver transplantation is adequate mobilization and division of all the outflowing veins of the caudate lobe.

Objective: To observe the effects of early enteral nutrition(EEN) on incidence of postoperative complication in gastric cancer patients. Methods: 150 patients with gastric cancer were randomly divided into early enteral nutrition group (n=82) and non-early enteral nutrition (N-EEN) group (n=68). The patients in group EEN were given enteral nutrition after operation, and the patients in group N-EEN were given total parenteral nutrition support. The postoperative complications were recorded. The serum albumin, prealbumin and transferrin were measured on postoperative day 1, 5 and 9. The serum level of alanine aminotransferase(ALT), bilirubin, blood urea nitrogen(BUN), creatinine, glucose, cholesteroland triglyceridewere monitored. Results: The complications occurred in 21patients. 5 of these patients belonged to EEN group and the other belonged to N-EEN group. In EEN group, the serum albumin, prealbumin and transferrin were significantly higher than in N-EEN group on postoperative day 9 (P

Objective:To elucidate the role of ERK1/2 MAPKs signal transduction in the protective effects of ischemic preconditioning during liver transplantation. Methods: Twenty-four rats were equally randomized into 4 groups: sham control (group A); liver transplantation (group B); ischemic preconditioning+liver transplantation (group C), and MEK inhibitor intervention+ischemic preconditioning+liver transplantation (group D). Serum AST and ALT were detected after operation and cellular ultrastructures were observed by transmission electron microscopy. Liver tissue ERK1/2 MAPKs phosphorylation activities were evaluated through determining ERK-1 protein phosphorylation by Western blotting. Results: Serum ALT and AST activity in group B and group D was significantly higher than those in group A, and remained normal in group C. Liver tissue ERK1/2 MAPKs phosphorylation activity increased significantly in group C, and the activation effect was inhibited in group B and D. Cellular ultrastructure was obviously damaged in group B and group D, and the damage was prevented in group C.Conclusion: Ischemic preconditioning has a protective effect on transplanted liver cells in which ERK1/2 MAPKs pathway plays a pivotal role.
