【Abstract】Objective To investigate the protective effects of epidermal growth factor (EGF) on pancreas of rats with acute pancreatitis(AP). Methods Seventytwo male SpragueDawley 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h, 12 h and 24 h after induction of AP, 8 animals in each group were sacrificed respectively， 4 ml of blood sample was withdrawn from heart，2 ml for the analysis of amylase activity and 2 ml for MDA content in serum.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 APEGF 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 APEGF 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 APEGF group decreased significantly compared with those in the AP group at 24 h. AI of pancreas in the APEGF 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.

Methods Ascitic AFU activity was measured in 213 patients (117 with benign ascites and 96 with malignant ascites) diagnosed with benign or malignant ascites. The diagnostic sensitivity (SEN), specificity (SPE), accuracy, positive predictive value (PV+), negative predictive value (PV-), positive likelihood ratio (LR+), negative likelihood ratio (LR-) and Youden index (YI) of AFU were assessed with receiver operating characteristic curve, and the diagnostic effectiveness of AFU was evaluated. Results The average level of AFU in the malignant group [(164.96±87.72) μmol/(L•h)] was significantly higher than that in the benign group [(104.02±62.07) μmol/(L•h)] (Plt;0.01). The area under the curve (AUC) of the ROC curve of AFU was 0.754±0.034 for malignant ascites diagnosis, and the optimal cut-off value was 101.95 μmol/(L•h). When an AFU level equal to or higher than 101.95 μmol/(L•h) was used to predict malignant ascites, the diagnostic sensitivity was 82.3%, specificity was 63.2%, accuracy was 72.8%, PV+ was 65.3%, PV- was 83.1%, LR+ was 2.23, LR- was 0.28 and YI was 0.455. Conclusion Detection of AFU activity in ascites is helpful to differentiate the diagnose between malignant and non-tuberculous benign ascites, which is a relatively ideal index to fit for clinical application of local hospitals.

Objective To investigate predictive value of procalcitonin (PCT) and C-reactive protein (CRP) levels for spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis ascites. Methods The clinical data of 140 patients with liver cirrhosis ascites treated in our hospital from January 2012 to January 2016 were retrospectively analyzed. According to the presence of SBP, these patients were divided into SBP group and non-SBP group. The clinical data were compared between these two groups. The receiver operating characteristic (ROC) curve was constructed to assess their sensitivities and specificities of PCT and CRP for diagnosis of SBP. Results The PCT and CRP levels of the SBP group were significantly higher than those of the non-SBP group (P<0.05). The differences of serum ALT, AST and white cell count between the SBP group and the non-SBP were not statistically significant (P>0.05). The ROC curve analysis showed that the area under the ROC curve of PCT and CRP were 0.895 and 0.926, their corresponding cut-off value 2.1 μg/L and 24.8 mg/L, the sensitivities were 86.9% and 89.5%, the specificities were 85.1% and 83.5%, respectively. Conclusion Abnormally elevated PCT and CRP levels might have an important detective value for SBP in patients with liver cirrhosis ascites.
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.
Objective To explore the feasibility of inguinal hernia repair in patients with cirrhotic ascites under day surgical mode. Methods The clinical data of patients undergoing elective inguinal hernia repair with concurrent cirrhotic ascites under the day surgical mode admitted to Xijing Hospital, the First Affiliated Hospital of the Air Force Military Medical University between December 2015 and March 2023 were retrospectively analyzed. The diagnosis, treatment, and postoperative conditions of the patients were analyzed and summarized. Results Ultimately, 8 patients undergoing elective inguinal hernia repair with concurrent cirrhotic ascites under day surgical mode were included. Some patients had bilateral hernias, with a total of 11 cases of hernias. All of these hernias were oblique hernias, including 1 case of recurrent hernia. The surgical methods for 10 cases of hernia were Lichtenstein surgery, and 1 case used laparoscopic retroperitoneal hernia repair. All 8 patients did not use antibiotics during the perioperative period. Only 1 case of recurrent inguinal hernia occurred after surgery. Another patient was admitted to liver disease specialist ward due to ascites, and later improved. No patients experienced serious complication or surgery related death. ConclusionsUnder the premise of effectively improving complications of cirrhosis, patients with stable cirrhotic ascites who have undergone strict screening can undergo inguinal hernia repair surgery under the day surgical mode. However, further large-scale studies are needed in the future to clarify their specific application conditions and indications for the use of antibiotic.
