To evaluate the role of octreotide in the treatment of severe acute pancreatitis (SAP). Seventy-six patients were divided into two groups (octreotide group, n＝38, control group, n＝38). All patients were treated by the same conservative regime. The octreotide group received octreotide. Results: The abdominal symptoms and signs, WBC count, serum amylase level, and volume of ascites were more effective controlled, with fewer complications occurred in octreotide group. Conclusion: Octreotide has a beneficial effect on the treatment of SAP, but the mechanism will be further investigated.
Objective To find the relation between donor liver cold preservation-reperfusion injury and hepatocellular apoptosis during liver transplantation. Methods Four groups of rabbit livers, which had experienced cold storage for 0,3,6,9hr respectively, were observed during their cold preservation-reperfusion by using TdT-mediated dUTP-biotion nickend labeling and electron microscope.Results Apoptopic hepatic parenchymal cells were obviously observed in reperfusing livers subsequent to cold storage. Furthermore, the longer the cold storage duration, the greater the number of apoptotic cells. On the contrary, no or rare apoptotic hepatic parenchymal cells was observed in all the groups at the end of cold preservation. Conclusion It suggests that apoptosis of hepatic parenchymal cells is markedly involved in donor liver cold preservation-reperfusion injury.
Objective To study the results of in situ microwave thermocoagulation therapy for liver neoplasms. Methods Thirty-one patients (male 28, female 3) with liver neoplasms underwent in situ microwave thermocoagulation therapy in recent 4 years were studied. The time of the therapy arranged from 2 to 6 minutes with the core temperature from 110℃ to 125℃. Twenty six of the thirty one (83.9%) were followed up. Results Ninty point three percent of these patients have a good result. The average survival time after the operation was 19.7 months. One-year and three-year survival rate were 77.4% and 38.7%, respectively. Conclusion The in situ microwave thermocoagulation therapy have the advantages of causing slight trauma, promoting repair, good tolerance and curative effectiveness. It’s a simple, safe and effective method with less adverse effect for treating the liver neoplasms, especially for unresectable neoplasms.
Experienc of nurtitional treatment to 7 patients with acute renal failure (ARF) and nitrogemia after biliarty (tract) surgery is reported in this article. Nittrogen source inn all cases was obtained from "Renal Amine" and "7% Vamin" etc,which are composed of 8 essential amino acids (EAA), and the nergery sources are mainly supplyed by Intralipid (20 or 10%) and suitable amount of glucose. The nutritional admicture of "all in one" were employed as parenteral nutrition (PN). Satisfactary curative effecs in these patients were obtained. The suthors consider that (a) the nutritional treatment of different casuses of ARF should be providing enough energy and more EAA requirments than in normal need to synthesizw non-essential amino acide (NEAA) and protein from excessive blood urea nitrogen (BUN) for redcuing pritein breakdown and nitrogemia, and (b) 20% Intralipid is an effective low-volume, highly calories nutritional agent specially in ARF patients with restiction of waterr.
ObjectiveTo study the relationship between hepatocellular apoptosis and glycogen contents during hepatic cold preservationreperfusion and its mechanism.MethodsBased on the model of four groups of rabbit livers with different hepatocellular glycogen contents, hepatocellular apoptosis and bax gene expression were observed during hepatic cold preservationreperfusion.ResultsApoptotic hepatocytes were obviously found in 60 minute reperfusing livers subsequent to 9 hour cold storage, and there was significant difference in the numbers of apoptotic hepatocytes among all the groups. In the same time, there was the close relationship between the levels of bax gene expression and the glycogen contents of hepatocytes.ConclusionIntracellular abundant glycogen may significantly depress the hepatocellular apoptosis during hepatic cold preservationreperfusion by decreasing hepatocellular bax gene expression.
Objective To discuss the way of animal model building of hepaticocholedochostomy(HC) and hepaticojejunostomy(HJ) and to compare the short-term effect. Metheds Twenty-nine dogs were divided randomly into control group(n=5) and the experimental group (stenosis of left hepatic duct, n=24). After 7 weeksof stenosis of left hepatic duct,24 dogs in the experimental group were divided randomly into HC subgroup (n=12) and HJ subgroup (n=12) .The operation time and the blood loss during operation were recorded and the hepatic function was detected.Results The diameter of left hepatic duct was significantly expended after 7 week’s stenosis. Hepaticocholedochostomy took shorter time and lost less blood than hepaticojejunostomy. The dogs in HC subgroup lost less weight than thosein HJ subgroup. In HC and HJ subgroups, the mortality rates were 1/12 and 3/12;the infectious rates of incision were 3/12and 5/12 respectively. Serum levels of total bilirubin and transaminase increased significantly in the 7th week after stenosis of left hepatic duct compared with before stenosis of left hepatic duct. However, Serum levels of total bilirubin and transaminase restored to normallevels after 1 month of HC or HJ.Conclusion It is feasible to establish animal model of bile duct reconstruction on the basis of stricture of bile duct. The dogs undergoing hepaticocholedochostomy have less trauma, better results than the dogs undergoing hepaticojejunostomy. Both hepaticocholedochostomy and hepaticojejunostomy are able to relieve the obstruction of bile duct.
