ABSTRACT
Objective To evaluate the significance of sIL 2R and TNF ? in chronic cor pulmonale.Methods The sIL 2R and TNF ? were detected by means of ELISA.The correlation with PaO 2 and PaCO 2 was analyzed using linear correlation.Results The levels of sIL 2R and TNF ? in patients at exacerbation stage were higher than that of remission stage and normal controls (P
ABSTRACT
Objective To discuss clinical effects of combined use of duodenoscopy and laparoscopy in the treatment of acute billiary pancreatitis(ABP).Methods The clinical data of 94 ABP patients who underwent minimally invasive treatment from February 2001 to Feburary 2006 were retrospectively reviewed.Among 94 ABP patients,59 patients had gallbladder stones were given laparoscopic cholecystectomy(LC)alone;14 patients had common bile duct stones received endoscopic nasobiliary drainage(ENBD),combined endoscopic sphincterotomy(EST)and LC;21 patients had both gallbladder and common bile duct stones received combined EST and LC.Results Postoperatively,in the whole group,only one patient had recurrent pancreatitis,one patient had hemobilia,and both cases followed ERCP+EST;two cases had lung infection,and one case had infection of abdominal incision.All of the 5 cases with postoperative compllcations were successfully treated by conservative therapy.The effective rate for the whole group was 100%.Conclusions Combined use of duodenoscopy and laparoscopy is significantly effective for treatment of acute biliary pancreatitis and this minimally invasive treatment is the ideal therapy for acute biliary pancreatitis.
ABSTRACT
Objective To study the significance of change of high mobility group box 1(HMGB1)level of pancreas in acute necrotizing pancreatitis(ANP)in rats.Methods ANP model was induced by retrograde injection of sodium taurocholate in pancreatic duct.Animals were divided randomly into three groups:control group,ANP group,and sodium butyrate treatment group(treatment group).The serum levels of TNF-? and IL-1? were measured by ELISA.The HMGB1 mRNA level of pancreas was detected by RT-PCR.Results The serum levels of TNF-? and IL-1? were quickly increased after the model was induced,and reached a peak at 6h,but decreased at 12h.The HMGB1 mRNA level of pancreas was increased significantly at 12h,and maintained to 24h.Whereas in treatment group,the HMGB1 level of pancreas was lower than ANP group(P
ABSTRACT
Objective To explore the effects of ethyl pyruvate (EP) on high mobility group box-1 protein (HMGB1) expression in severe acute pancreatitis (SAP) rats.Methods Ninety male wistar rats were divided randomly into three groups: Group A (SAP group); group B (SAP rats received ethyl pyruvate therapy); group C (control group). Specimens from rats in the three groups were taken at 3, 6, 12, 24 and 48 h after operation respectively. The concentration of plasma amylase and D-lactate the activity of malonyl dialdehyde (MAD) in the intestinal tissue were determined. The changes of morphological damage of intestinal tissue was observed by microscopy. The expression of HMGB1 in intestinal mucosa was observed by SP immunohistochemistry and the activity of HMGB1 was determined by western blot.Results Compared with group A, Ievels of plasma amylase, and D-lactate in group B decreased markedly (P
