Protective Effects of Epidermal Growth Factor on Pancreas of Rats with Acute Pancreatitis

【Abstract】Objective To investigate the protective effects of epidermal growth factor (EGF) on pancreas of rats with acute pancreatitis(AP). Methods Seventytwo male SpragueDawley rats were randomly divided into 3 groups: Control group, AP group and AP-EGF group. Subcutaneously injection of EGF (0.1 μg/g) were given to animals in the AP-EGF group after the establishment of the model of AP. The other two groups of animals received the same volume of saline. At 6 h, 12 h and 24 h after induction of AP, 8 animals in each group were sacrificed respectively， 4 ml of blood sample was withdrawn from heart，2 ml for the analysis of amylase activity and 2 ml for MDA content in serum. Ascites was sucked with dry gauzes and was weighed thereafter. Changes of pancreas morphology were evaluated at every time point. The same part of pancreas was removed for measurement of MDA content, apoptotic index (AI) and histologic changes. Results Histologic injury of the animals in the APEGF group was milder than that in the AP group. Ascites weight in the AP-EGF group decreased significantly compared with that in the AP group at 12 h and 24 h 〔(4.53±1.29) g vs (6.58±1.47) g, (7.64±1.85) g vs (11.96±2.13) g，P＜0.05，P＜0.01〕. Amylase activity in the APEGF group also decreased significantly compared with that in the AP group at 12 h and 24 h 〔(142.0±8.3) U/L vs (187.9±10.4) U/L, (194.3±10.4) U/L vs (253.3±8.6) U/L, P＜0.05，P＜0.01〕. MDA content in plasm 〔(2.34±0.23) μmol/L vs (3.15±0.38) μmol/L, P＜0.05〕 and in pancreas 〔(5.21±1.46) μmol/g vs (7.68±1.63) μmol/g, P＜0.01〕 in the APEGF group decreased significantly compared with those in the AP group at 24 h. AI of pancreas in the APEGF group increased significantly compared withthatintheAPgroupafteroperation〔(16.22±3.53)%〖KG4vs (7.35±1.04)%, (11.67±2.40)% vs (4.81±0.86)%, (6.38±1.42)% vs (1.97±0.21)%, P＜0.01〕. Conclusion EGF may accelerate the restoration of pathologic injury and alleviate the hemorrhage and edema of pancreas. It may also depress MDA content in plasm and in pancreas so that to lessen oxidative damage. EGF may protect pancreas by inducing cellular apoptosis.

Effect of Venous Retransfusion of Ascites on Treatment of Complicated Patients with Budd-Chiari Syndrome

Objective To explore the methods and effect of venous retransfusion of ascites on the treatment of the complicated patients with Budd-Chiari syndrome.Methods Eighteen complicated and (or) recrudescent patients with Budd-Chiari syndrome were treated by venous retransfusion of ascites between March 2006 and July 2009. The changes in abdominal girth, body weight, the urine volume of 24 h, liver function, renal function, and serum electrolyte measurements before and after treatment were compared. Results After retransfusion of 5 000 ml to 7 800 ml (mean 6 940 ml) ascites, the abdominal girth of patients decreased (Plt;0.05), the urine volume of 24 h tended to normal and during which no serious side-effect happened. The levels of serum BUN, CREA, prothrombin time (PT), and activated partial thromboplastin time (APTT) decreased significantly (Plt;0.05), furthermore the levels of total albumen and albumin increased significantly (Plt;0.05). The changes of serum electrolyte measurements were not significant (Pgt;0.05). The follow-up period for all the patients was in the range of 4 to 37 months (mean 19 months). Then 12 patients were treated by the second operation at 3-6 months after discharge. Conclusions The ascites retransfusion provides a safe and effective treatment option for patients with refractory ascites, and yields a higher likelihood of discharge compared with conventional paracentesis. It is useful in improving quality of life and winning the operational chance for such as patients with complicated Budd-Chiari syndrome.

Study on The Effect of Acute Suppurative Peritonitis Associated Ascitic Fluid on Experimental Liver Injury of Rats

Objective To study the effect and intrinsic mechanism of acute suppurative peritonitis associated ascitic fluid (ASPAAF) on experimental liver injury of rats. Methods Thirty-two male or female Sprague-Dawley (SD) rats were randomly divided into two groups: ASPAAF group (n=16) and control group (n=16), in which 8 ml ASPAAF or normal saline (NS) were injected into the peritoneal cavity, respectively. The rats were killed at each time intervals after peritoneal cavity injection (6 h and 12 h) respectively in two groups and specimens were made to detect the levels of serum TNF-α, endotoxin and liver function (AST, ALT and STB). The level of TNF-α in liver tissues was measured. The pathological change of liver was observed by microscope. Results The levels of TNF-α, endotoxin, ALT, AST and STB in serum and the levels of TNF-α in liver tissues at different time points were markedly higher in ASPAAF group compared with those in control group (P＜0.05), and these indexes increased with increasing time in ASPAAF group (P＜0.05). In ASPAAF group, hepatic tissue appeared hydrops, even spotty necrosis and the changes at 6 h and 12 h were not obvious different. No abnormal pathological change of hepatic tissue was found in control group. Conclusion ASPAAF can induce the injury of the liver in rats, which may involved in TNF-α and endotoxin.

Role of L-Arg in Acute Lung Injury Induced by Intra-Peritoneally Injection of Perforative Peritonitis Ascitic Fluids in Rats

Objective　To investigate the pathogenesis of acute lung injury in rats induced by intra-peritoneally injection of perforative peritonitis ascitic fluids（PPAF） and the role of L-arginine （L-Arg） in acute lung injury in this model. Methods　Perforative peritonitis （PP） models were established in 60 rats and PPAF were collected. Forty-eight rats were randomly divided equally into NS group，PPAF group, and L-Arg group. Rats were randomly subjected to death at 7 h and 12 h. Peripheral blood WBC were counted，levels of NO and malondialdehyde （MDA） in serum were examined. Lung injury score and wet/dry ratio were evaluated， and level of myeloperoxidase （MPO） in lung tissues and lung cell apoptosis were tested. Results　WBC count of peripheral blood, levels of NO and MDA in serum， level of MPO in lung tissue, lung injury score， wet/dry ratio， and lung cell apoptosis rate in PPAF group were significantly higher than that in NS group at each time point（P＜0.01）. Level of NO in serum in L-Arg group was higher than that in PPAF group （P＜0.01）， but lower level of MDA in serum， lower level of MPO in lung tissue and lung injury score，lower wet/dry ratio， and lung cell apoptosis rate were observed in L-Arg group（P＜0.05）. In PPAF group and L-Arg group， level of NO in serum， wet/dry ratio, and lung cell apoptosis rate were higher at 12 h than that at 7 h（P=0.000）. Serum NO level was in negative correlation with serum MDA level （r=-0.257，P=0.021）， MPO level in lung tissue（r=-0.444， P=0.011），and lung cell apoptosis（r=-0.351， P =0.010） in PPAF group and L-Arg group， but serum MDA level was in positive correlation with cell apoptosis（r=0.969， P＜0.001） in each group. Conclusions　Acute lung injury rats model can be established by intra-peritoneally injection of PPAF. Enhanced oxidizing reaction and cell apoptosis take part in the occurrence of acute lung injury. L-Arg plays a protective role in acute lung injury.

The efficacy and safety of drainage with abdominal catheterization in cirrhotic patients with large-volume ascites

Objective To investigate the efficacy and safety of abdominal indwelling catheterization for the patients with large-volume ascites. Methods A total of 84 patients with liver cirrhosis complicated with large-volume ascites admitted in the first affiliated hospital of Xi’an Jiaotong University from January 2015 to December 2015 were retrospectively analyzed. Patients were divided into two groups, one was the puncture group and another was the catheterization group. The efficacy and safety were evaluated. Results Forty-four patients were enrolled in catheterization group, whereas forty patients were enrolled in puncture group. Symptoms associated with ascites had been eased and patients’ qualities of life had been improved in 2 weeks in each group. The tube fell out rate was 27.3% for patients in catheterization group. There was no operation related complications such as death, bleeding and intestinal perforation occurred. Either Child B stage or Child C stage, the dynamic changes of liver function and renal function in catheterization group were comparable to those in puncture group. No adverse event such as catheterization-related or puncture-related infection was observed. Conclusion Abdominal catheterization is effective and safe in management of large amount of ascites complicated with cirrhosis, however, the high rate of tube-fell-out should be paid more attention.
