ABSTRACT
Objective To analyze and compare the effect of early surgical treatment and nonsurgical treatment for patients with severe acute pancreatitis.Methods Acccording to the including criteria,five randomized controlled trials of this topic were enrolled into the analysis.The detail about the trial design,characters of the subjects,results of the studies were reviewed and analysed by using Revman 4.2 software.Results Compared with nonsurgical treatment,early surgical treatment was associated with a significantly higher(incidence) of mortality(RR 3.42,95% CI 1.81～6.47,P=0.0002) and complications(RR 3.16,95% CI 2.15～4.64,P
ABSTRACT
Objective To study the effect of Qing Yi Tang(QYT) on bacterial and endotoxin translocation from intestine in acute hemorrhagic necrotizing pancreatitis(AHNP) in rats.Methods SD rats were randomly divided into 3 groups: AHNP group,AHNP +QYT treatment group and sham operation(SO) group.AHNP models were set up in the former two group,while the pancreas was only mobilized in SO group.After setting up the model,QYT was gavaged in the QYT group,while normal saline was gavaged in the SO group and AHNP group.The concentration of endotoxin(ET) and the DNA of E.coli expressoin in portal vein blood in three groups of rats were measured 24h later.Results The concentration of ET and amount of E.coli DNA in portal vein of QYT group were lower than those of AHNP group.Conclusions QYT can reduce significantly the concentration of ET and E.coli DNA in portal vein blood and decrease bacterial and endotoxin translocation from intestine in the AHNP rats.
ABSTRACT
Objective To investigate low molecular weight heparin(LMWH) therapy for pancreatic encephalopathy in severe acute pancreatitis(SAP).Methods SD rats were randomly divided into 3 groups:(1) Sham operation(S) group,(2) SAP group and(3) LMWH treatment(LT) group:LMWH was administrated at 4 hours after construction of SAP model.The levels of serum amylase,myelin basic protein(MBP),tumor necrosis factor alpha(TNF-?),interleukin 6(IL-6),brain water contents and pathological changes of pancreas and brain were measured at 24 h after models were set up in SAP and in S group,and 24 h after LMWH was administrated in LT group.Results(1) The levels of serum amylase,TNF-?,IL-6 in SAP group were significantly higher than those in S group and LT group(all P 0.05).(2) The brain water content in SAP group was significantly higher than that in S group and LT group(P
