Analysis of death cases in elderly patients with digestive tract disease during perioperative period / 中华老年医学杂志

renal dysfunction.Logisitic regression showed that cardiovascular disease and hypoalbuminemia were correlated with perioperative death rate significantly. Conclusions Improving the perioperative management is very important for lowering the perioperative mortality in elderly patients with digestive tract disease.

The effect of hyperbaric oxygen treatment on plasma endotoxin,sCD14 and plasma endotoxin inactivation capacity in acute necrotizing pancreatitis in rats / 中国普通外科杂志

Objective To study the effect of hyperbaric oxygen(HBO) treatment on plasma endotoxin,sCD14 and plasma endotoxin inactivation capacity(EIC) in acute necrotizing pancreatitis(ANP) in rats and its possible mechanism.Methods SD rats were randomly divided into control group,sham operation group,ANP group and ANP+HBO group.Rat ANP models were made by retrograde injection of 3.5% sodium(taurocholate)(2.5mL/kg) into the pancreatic duct.Thirty minues after models had been made,ANP+HBO group was treated by hyperbaric oxygen for 2h.At 3h,6h,and 10h after establishment of rat models,the plasma endotoxin,sCD14,EIC,TXB_2 and 6-K-PGF_(1a) leves were determined in each group.Results At 3h and 6 h after rat models were established,the levels of endotoxin,sCD14,and TXB_2 in ANP+HBO group were significantly lower than those in ANP group(P
