1Protective effect of early enteral feeding on postburn impairment of liver function and its mechanism in rats显示文摘AIM To study the protective effect of earlyenteral feeding(EEF)on the postburnimpairment of liver function and its mechanism.METHODS Wistar rats with 30% of total bodysurface area(TBSA)full-thickness burn wereemployed.The effects of EEF on the postburnchanges of gastric intramucosal pH,endotoxinlevels in portal vein,water contents of hepatictissue,blood concentrations of tumor necrosisfactor(TNF-α),plasma activities of alanineaminotransferase(ALT)and asparateaminotransferase(AST),as well as the bloodcontents of total(TB)and direct bilirubin(DB),total protein(TP)and albumin(ALB)wereserially determined within 48h postburn.RESULTS EEF could significantly improvegastric mucosal acidosis,reduce portal veinendotoxin level and water content of hepatictissue,as well as plasma concentrations of TNF-α at all timepoints after severe burns(P<0.01);postburn elevation of the plasma activities ofALT,AST and the contents of TB,DB wereeffectively prevented,whereas the plasmaconcentrations of TP and ALB were markedlyincreased 24 h and 48 h posturn in EEF groupcompared with that of the burn without EEFgroup(P<0.01).CONCLUSION EEF has significant beneficialeffects on the improvement of hepatic function in rats after severe burn,and is probably relatedwith an increase in splanchnic blood flow,reduction of the absorption of gut-originendotoxin and the consequent release ofinflammatory mediators.Zhu L Yang ZC Li A Cheng DC 2000World Journal of Gastroenterology2000,6,1:10
2Reduced gastric acid production in burn shock period and its significance in the prevention and treatment of acute gastric mucosal lesions显示文摘AIM To investigate the changes of gastric acidproduction and its mechanism in shock period ofsevere burn in rats.METHODS A rat model with 30% TBSA full-thickness burn injury was employed and thegastric acid production,together with gastricmucosal blood flow(GMBF)and energy charge(EC)were measured serially within 48hpostburn.RESULTS The gastric acid production in theacute shock period was markedly inhibited aftersevere burn injury.At the 3rd h postburn,thegastric juice volume,total acidity and acidoutput were already significantly decreased(P<0.01),and reached the lowest point,0.63mL/L±0.20mL/L,10.81mmol/L±2.58mmol/L and 2.23mmol/h±0.73mmol/hrespectively,at the 12th h postburn.Althoughrestored to some degree 24 h after thermalinjury,the variables above were stillstatistically lower,compared with those ofcontrol animals at the 48th h postburn.TheGMBF and EC were also significantly reducedafter severe burns,consistent with the trend ofgastric acid production changes.CONCLUSION Gastric acid production,as wellas GMBF and EC was predominantly decreased in the early postburn stage,suggesting that gastricmucosal ischemia and hypoxia with resultantdisturbance in energy metabolism,but notgastric acid proper,might be the decisive factorin the pathogenesis of AGML after thermalinjury,and that the preventive use of anti-aciddrugs during burn shock period wasunreasonable in some respects.Therefore,taking effective measures to improve gastricmucosal blood perfusion as early as possiblepostburn might be more preferable for the AGMLprevention and treatment.Zhu L Yang ZC Li A Cheng DC 2000World Journal of Gastroenterology2000,6,1:7
3Expression of co-stimulator 4-1BB molecule in hepatocellular carcinoma and adjacent non-tumor liver tissue,and its possible role in tumor immunity显示文摘AIM:To investigate the expression of 4-1BB molecule in hepatocellular carcinoma (HCC) and its adjacent tissues.METHODS:Reverse transcription-polymerase chain reaction (RT-PCR) was used to determine the gene expression of 4-1BB in hepatocarcinoma and its adjacent tissues,and peripheral blood mononuclear cells (PBMCs) from both HCC and health control groups.Flow cytometry was used to analyse the phenotypes of T cell subsets from the blood of HCC patients and healthy volunteers,and further to determine whether 4-1BB molecules were also expressed on the surface of CD4+ and CD8+ T cells. The localization of 4-1BB proteins on tumor infiltrating T cells was determined by direct immunofluorescence cytochemical staining and detected by confocal microscopy.RESULTS:4-1BB mRNA, which was not detectable in normal liver,was found in 19 liver tissues adjacent to tumor edge(<1.0cm).Low expression of 4-1BB mRNA was shown in 8 tumor tissues and 6 liver tissues located within 1 to 5cm away from tumor edge. In PBMCs, 4-1BB mRNA was almost not detected. Percentage of CD4^+, CD8^+ and CD3^+/CD25^+ T cells, as well as ratio of CD4 to CD8 revealed no difference between groups (P>0.05,respectively),while a significant lower percentage of CD3^+ T cell was found in HCC group as compared to healthy control group (P<0.05).However, 4-1BB molecules were almost not found on the surface of CD4+ and CD8+ T cells in HCC and healthy control group.Double-staining of 4-1BB^+/CD4^+ and 4-1BB^+/CD8^+ immunofluorescence on tumor infiltrating T cells was detected in 13 liver tissues adjacent to tumor edge (<1.0cm) by confocal microscopy.CONCLUSION: Although HCC may escape from immune attack by weak immunogenicity or downregulated expression of MHC-1 molecules on the tumor cell surface,tumor infiltrating T cells can be activated via other costimulatory signal pathways to exert a limited antitumor effect on local microenvironment. The present study also implicates that modulating 4-1BB/4-1BBL costimulatory pathway may be an effective immunotherapy strategy to augment the host response.Wan, YL Zheng, SS Zhao, ZC Li, MW Jia, CK Zhang, H 2004World Journal of Gastroenterology2004,10,2:6
