ObjectiveTo determine the characters of symptomatic pancreatic pseudocyst due to acute pancreatitis and effects of surgical treatment with two kinds of procedure （internal drainage or external drainage）. MethodsOne hundred and fifteen cases hospitalized during recent ten years were retrospectively analyzed.ResultsWe found that necrotic tissue existed in the pseudocyst in most cases and infection might occur in these pseudocyst. Although effect of two kinds of surgery was similar, the clinical course was different. The complications after surgery were fewer in patients underwent internal drainage than that with procedure of external drainage, and average hospital day was 7d in cases with internal drainage and 11d in cases with external one respectively. Surgery of internal drainage used in treatment was not only successful in noninfectious and single pseudocyst, but in infectious or multiple seudocyst.ConclusionInternal drainage should be used in most cases and considered as the first selection in surgery of pseudocyst due to acute pancreatitis.
Objective To summarize the role of inflammatory cytokines in the pathogenesis of acute pancreatitis (AP) and gut barrier dysfunction in recent years. Methods Literatures on cytokines and experimental pancreatitis as well as clinical pancreatitis were collected and reviewed. Results Tumor necrosis factor-α and other inflammatory cytokines were elevated significantly during pancreatitis in many tissues, especially in pancreas and alimentary tract, in a fashion independent of the animal model used. Anti-cytokine therapy could decrease the concentration of the cytokines in experimental animal. Conclusion Inflammatory cytokines are believed to be primarily responsible for the pathogenesis of acute pancreatitis and its associated distant organ dysfunction. Further study of the nature of these cytokines may provide a new approach to treating this disease.

【Abstract】Objective To investigate a more rational modality which is in the treatment of severe acute pancreatitis (SAP) and effective in preventing liver from damages due to SAP. Methods SAP model was established by retrograde injection of 5% sodium taurocholate (1.0 ml) in the subserosa of pancreas in rats (n=80) weighting 200-250 g.The rats were catheterized using PE-50 angiocatheter from femoral artery to celiac trunk. Then they were randomly divided into four groups. Twenty animals served as controls (A group) and received only fluid infusion. The 40 animals, B and C group (20 animals in each one group) received continuous regional arterial infusion (CRAI) of somatostatin （4 μɡ/kg） and the medicines improving microcirculatory (dextran-40 1.5 ml, dopamine hydrochloride 5 μg/kg, anisodaminum 1.5 ml/kg) respectively. The other 20 animals (D group) were treated by somatostatin combined with the medicine improving microcirculatory through CRAI simultaneously with the induction of pancreatitis. The AST, ALT, ALP and serum amylase were recorded, the liver and pancreas tissue were observed pathologicaly after 6 hours. Results There were a ignificant decrease in the serum amylase in B group (Plt;0.05) and D group (Plt;0.05). The AST, ALT, ALP was decreased in B and D group (Plt;0.05). The damage to liver and pancreas were reduced in D group. Conclusion CRAI is effective in preventing liver damages due to SAP and is an effective way in the treatment of SAP.
ObjectiveTo explore the regulation of nuclear factorκB (NFκB) on tumor necrosis factorα (TNFα) expression in the liver and its role in liver injury in rats with acute pancreatitis.MethodsSeventytwo Wistar rats were randomly divided into three groups: acute pancreatitis group (AP), acute pancreatitis treated with pyrrolidine dithiocarbamate (PDTC) group (APP) and sham operation group (SO). The hepatic NFκB activities were determined with electrophoretic mobility shift assays. The expressions of hepatic TNFα mRNA were detected with RTPCR. The levels of serum alanine aminotransferase (ALT) were also measured.ResultsThe NFκB activities were significantly higher in AP and APP groups than those in SO group 3-6 hours after operation. The expressions of TNFα mRNA were ber in AP and APP groups than those in SO group 3-24 hours after operation. The levels of serum ALT were also significantly higher in these two groups than those in SO group 3-24 hours after operation. However, compared with AP group, the activities of NFκB, the expressions of TNFα mRNA and the levels of ALT significantly decreased in APP group.ConclusionThe activation of hepatic NFκB is associated with the liver injury by regulating TNFα mRNA expression in acute pancreatitis.
【Abstract】Objective To investigate the preventive role of selective decontamination of the digestive tract (SDD) in gut-originated endotoxemia in acute necrotizing pancreatitis (ANP). Methods A lethal model of ANP was reproduced in Wistar rats by retrograde infusion of artificial bile into the main pancreatic duct. Normal control group (n=6), sham operation group (n=6), ANP group (n=14) and ANP+SDD (polymycin E, tobramycin and nystatin mixture) group (n=8) were randomly devided. Visceral pathologic changes, serum levels of TNFα and IL-1β, intestinal bacterial flora, plasma D(-)lactate and endotoxin contents, as well as the mortality were examined at 72h after operation in each group. Results Necrosis and inflammation of pancreas, with a remarkable elevation of serum TNFα and IL-1β and intestinal flora disturbance (with E.Coli content risen significantly) were seen in ANP rats. Simultaneously, ANP rats displayed elevated plasma concentration of D(-)lactate and endotoxin. In SDD group, enterobacteraceae and yeast were markedly depressed, while anaerobes were well preserved, with the value of B/E 〔Bifidobacterium/E.Coli, log10(CFU/CFU）〕 elevated in the ileac mucous membrane (1.73±1.23 vs -0.37±0.72 in ANP group,P＜0.01) and in the caecum content (∞ vs 0.88±0.77). In addition, depressed levels of D(-)lactate 〔（3.95±1.83） mg/L vs （8.05±3.05） mg/L in ANP group,P＜0.01〕, endotoxin 〔（0.227±0.084） EU/ml vs （0.423±0.155） EU/ml in ANP group, P＜0.01〕 and TNFα 〔（15.41±10.32） ng/L vs （46.79±24.31） ng/L in ANP group P＜0.01〕 in systemic or portal vein were observed in the SDD group. Moreover, SDD group displayed a declined 72h mortality(14.3% vs 58.8% in ANP group, P=0.005). Conclusion ANP is associated with gut barrier disorder and gut flora imbalance, which may exacerbate the process of gut-originated endotoxin translocation. By protecting gut flora and gut barrier against disorder, SDD attenuates ANPrelated endotoxemia and improves the outcome. SDD is advisable for the prophylaxis of gut-originated endotoxemia complicated from ANP.
ObjectiveTo explore clinical effect of enteral nutrition (EN) through nasojejunal tube in severe acute pancreatitis (SAP).MethodsThe clinical and pathological data of 76 patients with SAP who met the inclusion criteria and treated in the Third People’s Hospital of Henan Province from June 2015 to December 2018 were retrospectively collected. According to the nutritional support therapy adopted in the course of treatment, the patients were divided into an EN group (n=44) and a parenteral nutrition group (PN group, n=32), the patients in the EN group were given the EN through the nasojejunal tube and the patients in the PN group were given the routine PN. The APACHE Ⅱ and SOFA scores, nutritional status, and immune function were observed before the treatment and on week 2 after the treatment in the two groups.ResultsThere were no significant differences in the general data of the gender, age, body mass index, etc. between the two groups (P>0.050). ① The score of APACHEⅡ or SOFA score on week 2 after the treatment in both groups was significantly lower than that before the treatment (P<0.050), which in the EN group was significantly lower than that in the PN group on week 2 after the treatment (P<0.050). ② The levels of albumin and prealbumin were increased significantly and the hemoglobin level was decreased (P<0.050) on week 2 after the treatment as compared with those before the treatment in the two groups (P<0.050), which in the EN group were significantly higher than those in the PN group on week 2 after the treatment (P<0.050). ③ The CD4, CD8, and CD4/CD8 and IgG, IgM, and IgA on week 2 after the treatment were significantly lower than those before the treatment in these two groups (P<0.050), which in the EN group were significantly higher than those in the PN group on week 2 after the treatment (P<0.050). ④ The levels of endotoxin, D-lactic acid, diamine oxidase, and serum high mobility group protein B1 on week 2 after the treatment were significantly lower than those before the treatment in the two groups (P<0.050), and which in the EN group were significantly lower than those of the PN group on week 2 after the treatment (P<0.050). ⑤ The complications rate in the EN group was significantly lower than that in the PN group [20.45% (9/44) versus 53.13% (17/32), χ2=8.786, P=0.003].ConclusionEN through nasojejunal tube has a good effect on patients with SAP, which is helpful to improve their immune and nutritional status.
