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.
目的 探讨胃大部切除术后残胃功能性排空障碍（FDGE）的发病机理、诊断及治疗。方法 对1993~1998年我科256例胃大部切除术患者的临床资料进行回顾性分析。结果 本组共发生FDGE 12例，发生率为4.7％(12/256)，均发生于术后3~12天。于1周内治愈1例(8.3％)，2周内治愈8例(66.7%)，3周内治愈11例(91.7%)； 所有患者于32天之内经保守治疗治愈出院。结论 术后残胃和远端空肠正常的运动功能破坏是发生FDGE的主要原因； 消化道造影及胃镜检查是诊断本病及与机械性梗阻相鉴别的重要方法； 采取非手术治疗一般可治愈，针对胃排空动力学机理采用促胃肠动力药物能收到较好的疗效。
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.
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.
The substitution of ρ-shaped jejunum for stomach in 64 patients with gastric carcinoma after total gastrectomy is reported . Survival rate of the first, third anad fifth year afer surgery were 71.8%,42.2% and 34.4% respectively.Postoperative death and complications with fistula of anastomotic stoma , refulx esophagitis and dumping syndrome were not encountered in this all series. These results show that the operative procedure is a simple, safe, and can be accomplished within short time and that the quality of living of the patient is good.
Objective To prepare the immunonanospheres［SC3Ab-HSA(5-Fu)-NS］ against human colorectal cancer and evaluate its immunoreactivity and effects on cancer. Methods SC3Ab-HSA(5-Fu)-NS was prepared by intermolecular cross-linking the monoclonal antibody SC3Ab with human serum albumin nanospheres containing 5-Fu ［HAS(5-Fu)-NS］ via new hetero-bifunctional crosslinker SPDP. Condensation test and immunoflurecence were used to evaluate the immunoreactivity, the specific binding of SC3Ab-HSA(5-Fu)-NS with colorectal cancer cell line SW1116 was observed by microscope and electron microscope. The specific cytotoxic effects on target cells were evaluated in vitro by MTT assay. SC3AbHSA(5-Fu)-NS, HSA(5-Fu)-NS and 5-Fu were injected into nude mice bearing human colorectal carcinoma, to study the inhibitory activity of SC3Ab-HSA(5-Fu)-NS in vivo. Results The immunoreactivity of SC3Ab-HSA(5-Fu)-NS was well preserved. SC3Ab-HSA(5-Fu)-NS can bind the SW1116 cells specifically. The IC50 value for SC3Ab-HSA(5-Fu)-NS on SW1116 cells was 24.6 μg/ml,which was lower than that of HSA(5-Fu)-NS(345.3 μg/ml) and 5-Fu(325.6 μg/ml). The inhibitory rate of SC3Ab-HSA(5-Fu)-NS on the growth of colorectal cancer xenografts was significantly higher than that of HSA(5-Fu)-NS or 5-Fu(P＜0.001).Conclusion SC3Ab-HSA(5-Fu)-NS has immunoreactivity and specific active targeting to the colorectal cancer cells. The anticancer ability of SC3Ab-HSA(5-Fu)-NS is significantly higher than that of HSA(5-Fu)-NS and 5-Fu.
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.
