Objective To evaluate the effect of enteral nutrition (EN) versus total parenteral nutrition(TPN) on gut barrier function in patients with severe acute pancreatitis (SAP). Methods Sixtythree patients with SAP enrolled from 4 hospitals were randomly assigned into EN group(29 cases) and TPN group(34 cases). EN group patients were fed via a spiral nasojejunal feeding tube placed routinely by endoscopy or fluoroscopy, and TPN group patients were nourished intravenously with TPN during the same period. The changes of serum endotoxin, diamine oxidase, and urinary excretion of lactulose and mannitol ratio (L/M) were observed. Results Plasma concentration of endotoxin were markedly decreased in EN group as compared with that in TPN group at the 7th,14th ,21th day of entry trial [(39. 30 ± 15. 82) EU/L vs (73.05 ±21.16) EU/L,(22.64 ±14.31) EU/L vs (49.34 ±24.54) EU/L,(14.81 ± 10.93)EU/L vs ( 30. 08 ± 14. 10 ) EU/L, P ＜ 0. 05]. Plasma concentration of diamine oxidase were markedly decreased in EN group as compared with that in TPN group at the 7th, 14th day of entry trial [(9. 97 ± 3. 84)U/Lvs (19.89±9.89)U/L,(5.42±1. 84) U/Lvs (8.79 ±4.08) U/L, both P ＜ 0. 05]. The urinary L/M decreased significantly in EN group than those in TPN group at the 7th, 14th,21th day of entry trial (0.28 ±0.25 vs 0. 65 ±0.45,0.21 ±0. 18 vs 0.54 ±0.41,0.08 ±0.04 vs 0.29 ±0.06, all P＜0.05).Conclusion EN has better effect on improving intestinal barrier function than TPN in treatment of patients with SAP.

AIM:To investigate the effects of ethane 1,2-dimethanesulfonate (EDS) preconditioning on renal ischemia/reperfusion (I/R) injury in male Sprague-Dawley (SD) rats.METHODS: Male SD rats (n=48) were ran-domly assigned to 6 groups:blank, sham, I/R, EDS+I/R, EDS+testosterone (TST) +I/R, and castration (Cast)+I/R.The renal pedicles were bilaterally occluded with a microvascular clamp for 45 min to establish renal I/R-induced in-jury model.Bilateral orchiectomy was conducted 2 weeks before surgery .EDS (75 mg/kg) was intraperitoneally injected 5 d before operation .Blood samples were collected 24 h after reperfusion from the vena orbitalis posterior plexus .Luteinizing hormone (LH), TST, serum creatinine (SCr), blood urea nitrogen (BUN), and kidney injury molecule-1 (KIM-1) were detected.The renal tissues were harvested to measure the level of TNF-αand the expression of Fas mRNA and caspase-3 protein.RESULTS:Serum TST levels in EDS +I/R group and Cast +I/R group were below the minimum detectable threshold.Compared with other groups , the rats in EDS+I/R group and Cast +I/R group had higher levels of SCr , BUN and KIM-1 (P<0.05).SCr and BUN levels showed no significant difference between EDS +I/R group and Cast +I/R group (P>0.05), but KIM-1 level in EDS+I/R group was lower than that in Cast +I/R group (P<0.05).After reper-fusion for 24 h, the levels of TST and LH in EDS +I/R group, Cast+I/R group and EDS+TST+I/R group were lower than those 1 h before operation (P<0.05).Compared with Cast+I/R and I/R group, the TNF-αlevel and expression of Fas mRNA and caspase-3 protein were significantly decreased in EDS +I/R group ( P<0.05 ) .CONCLUSION: EDS preconditioning substantially reduces the serum TST level , thus attenuating I/R-induced acute renal injury .TNF-α-induced Fas/FasL pathway may be involved in this process .

Objective To study the profile of peripheral blood cortisol concentration in patients with hepatitis B virus (HBV)-related acute on chronic liver failure (ACLF) and its association with disease severity and predictive value on prognosis.Methods Forty-five patients with HBV-related ACLF,including 15 patients in early-stage,15 in medium stage and 15 in end-stage; and 15 patients with severe chronic hepatitis B (CHB) were also enrolled.Peripheral blood cortisol concentration was tested by chemiluminesence immunoassay.SPSS version 18.0 was used to compare peripheral blood cortisol concentration among different groups and analyze its correlation with prothrombin activity (PTA),total bilirubin (TBil),albumin (Alb),alanine aminotransferase (ALT),aspartate aminotransferase (AST),HBV DNA,international normalized ratio (INR) and model for end-stage liver disease (MELD) scores.The independent risk factors of prognosis in patients with HBV-related ACLF were determined by performing Logistic regression analysis.Results The concentrations of peripheral blood cortisol in severe CHB group,early stage ACLF group,medium stage ACLF group and end-stage ACLF group were (595.6±114.0),(496.0±87.2),(303.9±81.1),and (183.8±71.8) nmol/L,respectively.A decreasing trend was observed and the differences among groups were statistically significant (F =63.93,P ＜ 0.01).Peripheral blood cortisol concentration were significantly different among subgroups of patients with MELD＜30,followed by 30-40 and ＞40(F 9.01,P＜0.01).Peripheral blood cortisol concentration in patients with ACLF was positively correlated with PTA level (r=0.83,P＜0.01),and inversely correlated with TBil (r =-0.34,P＜0.05),MELDscore (r =-0.60,P＜0.01),AST/ALT (r =-0.35,P＜0.05),and INR (r=-0.59,P＜0.01).Association with Alb,ALT,AST and HBV DNA was not observed.According to multivariate Logistic regression analysis,MELD score,cortisol level,Alb and total cholesterol were independent risk factors of prognosis for patients with ACLF.Serum cortisol concentration in survival group of HBV-related ACLF was higher than that in death group,while the death group exhibited a gradually decreasing trend.Conclusions The peripheral blood cortisol concentration decreases in patients with HBV-related ACLF,which is related to the degree of liver dysfunction,disease severity and prognosis of patients.Moreover,the lower level of cortisol concentration indicates poor short-term prognosis in patients with HBV related ACLF.

Objective To investigate the role of metastatic lymph node ratio (MLR) in the evaluation of prognosis of patients with gastric cancer (GC) at different lymph node numbers examined.Methods Clinical data were reviewed retrospectively in a total 535 patients who underwent surgery for GC.Spearman correlation analysis between MLR or number of metastatic lymph nodes (N) and examined lymph node numbers,Kaplan-Meier method was used for comparison survival rates of N stage and MLR stage.A receiver operating characteristic (ROC) curve was used to evaluate the role of N stage and MLR stage in the prognosis of GC patients.Results Metastatic lymph node ratio and number of metastatic lymph nodes correlated with the examined lymph node numbers (r =0.146,r =0.378,P ＜ 0.01,P ＜ 0.001).The 5 year survival rate of MLR0,MLR1,MLR2 and MLR3 patients were 57.5％,69.9％,40.0％ and 21.7％ respectively when examined lymph node numbers ＜ 6 (P ＜ 0.01).The 5-YSR of MLR0,MLR1,MLR2 and MLR3 patients were 86.8％,59.2％,35.8％ and 39.2％ respectively when between 6-10 (P ＜0.001) and the 5-YSR of MLR0,MLR1,MLR2 and MLR3 patients were 88.7％,62.5％,0 and 17.7％ respectively when they ＞ 10(P ＜0.001).AUC of MLR staging was 0.68 ±0.05 when the numbers ＜ 6 (P ＜ 0.001).AUC of MLR staging was 0.72 ± 0.04 at numbers 6-10 (P ＜ 0.001).AUC of MLR staging was 0.79 ± 0.03 when numbers ＞ 10 (P ＜ 0.001).Conclusions MLR was less influenced by lymph node number examined than N.MLR stage has potential superiority to that the N stage in assessing prognosis of GC patients,especially for patients with more than 6 lymph nodes examined.

Objective To evaluate the osteogenesis of a novel borosilicate glass materials combined with platelet-rich plasma in repairing segmental bone defects. Methods 36 New Zealand white rabbits which bilateral radius were resected into l.5cm bone defect, were divided into 4 groups averagely depending on implanted materials: group A (one side: D-Alk- 1B, another side: D-Alk- 1B +PRP), group B (one side:D-Alk- 1B +PRP, another side: β-TCP); group C (one side: β-TCP, another side: experimental bone defect),and group D(one side:D-Alk-1 B,another side :experimental bone defect). The specimens were examined after 4, 8,12 weeks; the osteogenesis was evaluated through gross observation, X-ray radiograph,histological examination,scanning electron microscope and Micro-CT. Results There were similar results about gross observation,X-ray radiograph ,histological examination. After 4, 8, 12 weeks ,D-Alk-1B materials, β-TCP and D-Alk-1 B + PRP group had better osteogenesis ability than the experimental control group (P ＜0.05); D-Alk-lB + PRP had the best performance, better than D-Alk-1B and β-TCP (P＜0.05); D-Alk-1B were similar to β-TCP (P＞0.05). D-Alk-1 B materials degradated faster than β-TCP materials, and the porous structure of the materials disappeared after degradation. D-Alk-1B materials intergrated with host's bone was better than β-TCP materials. Conclusion D-Alk-1B material have good biological activity, histocompatibility and biodegradation and simiar presence of bone formation compared withβ-TCP in the aspect of repairing the segmental bone defect, the combination of PRP and D-Alk-1 B strengthened osteogenesis in vivo.
