ABSTRACT
Objective To compare the effects of venous port access ( VPA ) with peripherally inserted central catheters ( PICC) in patients with breast cancer .Methods 120 cases with breast cancer were divided into 2 groups from Jan.2009 to Dec.2010,among whom 60 cases were with VPA when receiving operation , and the other 60 cases were with PICC after the operation .The success rate of catheterization , duration of catheter in-dwelling and catheter-related complications of the 2 groups were compared .Results The one-time success rate of catheterization was 100%in VPA group and 66.7%in PICC group .The catheters were retained for more than 12 months in 59 cases in VPA group,while only 4 cases in PICC group retained catheter for more than 12 months. The complications occurred to 1 case in VPA group ( 1.7%) and 9 cases in PICC group ( 15%) .Conclusion VPA is an ideal pathway for chemotherapy of patients with breast cancer , which can reduce nursing work and is worth to be promoted in clinical practice .
ABSTRACT
Objective To analyze the related factors associated with the effect of Roux-en-Y gastric bypass in Goto-Kakizaki rats.Methods In GK rats undergoing Roux-en-Y gastric bypass,the weight,food intake,and the fasting blood glucose were retrospectively analyzed before surgery and 1,3,6,12,24 weeks after surgery,and the glycosylated haemoglobin concentrations were retrospectively analyzed before surgery and 4,12,24 weeks after surgery.According to preoperative glycosylated haemoglobin concentrations,GK rats were divided into 3 groups(group A,HbAlc 6.5％-7.9％; group B,HbAlc 8.0％-9.9％ ; group C,HbAlc ＞ 10％).Results The fasting blood glucose and the glycosylated haemoglobin concentrations significantly decreased 1 week after surgery(P ＜ 0.01),on 24 weeks after operation,the fasting blood glucose levels decreased from(12.1 ± 3.0)mmol/L to(7.6 ± 1.3)mmol/L,and the glycosylated haemoglobin concentrations declined from(9.2％ ± 1.8％)to(6.3％ ± 0.8％).Preoperative fasting blood glucose was(11.1 ± 2.2)mmol/L and(15.8 ± 2.3)mmol/L respectively,and the preoperative glycosylated haemoglobin concentration was(8.6％ ± 1.4％)and(11.5％ ± 1.4％)respectively(P ＜ 0.01).Non-conditional Logistic regression analysis identified preoperative glycosylated haemoglobin concentrations as an independent predictor for the cure rate(P ＜ 0.01); Differences were significant between group A and group C,and group B and group C on the efficiency of the surgery(P ＜0.01).Conclusions Significant correlation established between glycosylated haemoglobin concentrations and the efficiency of the surgery,especially for those rats with preoperative HbAlc ＜ 10％.
ABSTRACT
Objective To evaluate the effect of Roux-en-Y gastric bypass on patients with different preoperative glycosylated hemoglobin (HbAlc) level.Methods From Jan.2008 to Dec.2009,54 patients with gastric lesions and type 2 diabetes mellitus were preoperatively divided into 3 groups:group A (HbAlc:6.5％ -7.9％ ),group B ( HbAlc:8.0％ - 9.9％ ),and group C ( HbAlc ＞ 10％ ).They all underwent Roux-en-Y gastric bypass.The fasting plasma glucose(FPG) and HbAlc concentration were measured before surgery and 12,24,48 weeks after surgery.The antidiabetic medication was analyzed before surgery and 48 weeks after surgery.Results FPG and HbAlc concentration decreased significantly after surgery ( P ＜ 0.01 ).FPG and HbAlc concentration differed greatly between the different groups ( P ＜ 0.01 ).With the increase of preoperative HbAlc,FPG and HbAlc concentrations were poorly controlled after surgery.Conclusion Roux-en-Y gastric bypass surgery can effectively improve glucose metabolism for patients with preoperative HbAlc ＜ 10％.
