RESUMO
Objective To build rat orthotopic liver transplantation model and use this model as an experimental animal model for further research about liver transplantation.Methods Based on the classic two-cuff technique,a variety of skills were integrated,such as abdominal aorta perfusion first before ligation,suprahepatic inferior vena cava single continuous suture,preoperative and postoperative rehydration,hepatic portal vein and infrahepatic vena cava blocked by mosquito's haemostatic forceps.At last,the postoperative survival rates of 2 days and 2 weeks were recorded.Results Donors' operation time was (35±2) min,cuffing time was (7.0±1.5) min,receptors' operation time was (80±15) min,anhepatic phase was (21±3) min.The 2-day survival rate was 92 ％ (46/50) and 2-week survival rate was 86 ％ (43/50).Conclusion To some extent,the improved methods can not only reduce the difficulty of orthotopic liver transplantation operation,but also to create a uniform,stable and reliable orthotopic liver transplantation model.
RESUMO
@# ObjectiveTo explore the effect of glucocorticoid inhaled on bone metabolism, bone density and adrenal function in children with asthma.Methods60 children were randomly divided into the treatment group and control group with 30 cases in each group, and having 30 pneumonia children as another control. Children of the treatment group were treated with budesonide (200～600 μg/d) inhaled, asthma cases in the control group without budesonide inhaled. Bone metabolism, bone density and adrenal function of children in three groups were compared.ResultsAfter 18 months treatment, there were no significantly differences of bone metabolism, bone density and adrenal function among children of three groups (P>0.05).ConclusionThe treatment of glucocorticoid inhaled is safe to asthma children.
