ABSTRACT
Objective We discussed the nursing of patients with superior mesenteric artery syndrome (SMAS) through duodenal circular drainage operation. Methods We carried out a retrospective analysis for 42 SMAS patients undergoing duodenal circular drainage operation from. 1959 to 2007. They were given preoperative psychological nursing, correct lying style, postoperative nutritional support and health education instruction. The treatment effect was observed. Results All patients cured and left hospital. The treatment effect was good after one to fifteen years of follow-up visit. Five patients who changed to adopt duodenal circular drainage operation also got good result after nine to ten years of follow-up visit. The incidence of anastomotic ulcer and anastomotic stenosis as well as reflux gastritis was not seen. Conclusion SMAS could be cured earlier through duodenal circular drainage operation and effective nursing.
ABSTRACT
Objective: We observed the influence of recombinant human growth hormone(rhGH) on protein metabolism in hepatocirrhotic rats and investigated mechanisms. Methods: Ninety rats were randomized into three groups(n=30 for each group): group A(normal rats), B(cirrhotic rats) and C(cirrhotic rats receiving rhGH). Rats in group C were subcutaneously given rhGH with a dosage of 1 U/(kg?d) for up to 1 week. The plasma concentrations of albumin(ALB), prealbumin(PA), transferrin(TF) and insulin-like growth factor-1(IGF-1) were detected on experimental day 14. And liver biopsy was taken to examine the expression level of albumin mRNA with TR-PCR. Results: The albumin, prealbumin, transferrin and IGF-1 levels in groups A and C were significantly higher than those in group B. The expression level of albumin mRNA in grup C was significantly higher than that in group B. Conclusions: The rhGH can improve the level of IGF-1 in plasma and improve the expression of albumin mRNA. Moreover, it may significantly improve the synthesis of protein and attenuate hypoproteinemia in cirrhotic rats.
