Objective To investigate the activation and clinical significance of the mammalian target of rapamycin (mTOR) pathway related protein and eukaryotic translation factor 4E-binding protein 1 (4E-BP1) in gastric cancer.Methods The activation of mTOR and 4E-BP1 in gastric cancer tissues of 38 surgical patients were detected by immunohistochemical method.The differences of phosphorylated mTOR and 4E-BP1 expression among cancerous tissues,para-cancerous tissues and normal gastric mucosa tissues and dinicopathological variables were analyzed by Chi square test and Kruskal-Wallis test.Results The positive expression rate of phosphorylated mTOR in the gastric cancerous tissues was significantly higher than that of para-cancerous tissues and normal tissues [71.1％ (27/38),50.0 ％ (19/38) and 44.7 ％ (17/38),x2 =11.031,P =0.026].The positive expression rate of downstream protein 4E-BP1 in the gastric cancer tissues was also significantly higher than that of paracancerous tissues and normal tissues [68.4％(26/38),57.9％(22/38) and 28.9％ (11/38),x2 =13.943,P=0.007].There was no correlation between phosphorylated mTOR and 4E-BP1 expression and tumor Lauren's sub-type,infiltration,differentiation degree,lymph node metastasis and patient's age.There was statistical significant difference between activated 4E-BP1 expression and tumor size in gastric cancer (H=3.86,P＜0.05).Conclsions mTOR pathway was over activated in gastric cancer.There was difference between phosphorylation degree of its downstream protein 4E-BP1 and the tumor size.

Objective To observe the changes in gut mucosal barrier and gut-origin bacteria-endotoxin translocation in acute necrotizing pancreatitis (ANP) rats. Methods Wistar rats were divided randomly into normal group (n=6), sham operation group (n=30) and ANP group (n=39). ANP was introduced by infusion of artificial bile into biliopancreatic duct. Morphology of pancreas and intestine were observed and tight junction on ileum epithelia were assessed by cryofracture replicas electroscopy. Plasma levels of D-lactic acid and endotoxin were examined at various time points. The rates of bacterial translocation to abdominal organs were also calculated. Results Mucosal and tight junction damages of the gut were found during early stage of ANP. Simultaneously, plasma D-lactate levels increased and endotoxemia occurred. The rate of bacterial translocation to organs was 59.5% 72h after ANP occurred. Conclusions Gut barrier function can be injured in the early stage of ANP, and resulting in gut origin bacteria-endotoxin translocation, which may be the originator of systemic inflammatory reaction and secondary infection of the pancreas.

Objective To compare the contrast-enhanced ultrasonography (CEUS) manifestations of pNENs with the pathological changes and to explore the clinical value of CEUS in diagnosis of pNENs. Methods The CEUS of sixteen pathologically diagnosed pNENsfrom April,2012 to February,2014 were retrospectively observed.The CEUS of thirty pathologically diagnosed pancreatic carcinomas during the same period were taken as the control group.The enhancement extent and enhancement patterns of CEUS in pancreatic tumors were analyzed. The specimens of pNENs were stained with HE and CD34 immunochemistry.The grading of interstitial content and Ki-67 index were obtained on HE-stained slices and microvascular density(MVD) were obtained on CD34 immunochemistry stained slices.Spearman rank test analysis was employed to analyze the correlation.Results Among the 16 cases of pNENs,12 cases (75.0%) demonstrated hyper-or iso-enhancement,which included 6 cases (37.5%) showing homogeneous enhancement and 6 cases (37.5%) showing inhomogeneousen hancement,and the other 4 cases demonstrated hypo-enhancement. Among 30 cases of pancreatic carcinomas,25 cases (83.3%) demonstrated hypo-enhancement and 5 cases (16.7%) hyper- or iso-enhancement,and 21 cases (70.0%) demonstrated homogenous enhancement,and 9 cases(30.0%)inhomogeneous enhancement.Taking hyper-or iso-enhancement on CEUS as the diagnostic criteria,its diagnostic sensitivity,specificity,positive predictive value,negative predictive value,and accuracy were 75.0%,83.3%,70.6%,86.2%,80.4%respectively.Negative and positive correlation of the enhancement extent of pNENs with the interstitial content(r =-0.880,P < 0.001) and MVD (r =0.658,P =0.003) were observed,respectively.Six tumors with inhomogeneous enhancement contained cystic degradation or necrosis under microscope. Conclusions CEUS is an effective and non-invasive diagnostic approach for pNENs and can reflect the pathological changes.Hyper-or iso-enhancement of CEUS is typical appearance of pNENs.
