Objective To evaluate the consistency and diagnosis importance among three assays of Micral-Test strip,DCA 2000 analyzer and radioimmunoassay.Methods A total of 133 random urine samples of patients with diabetes were determined positive or questionable positive by Micral-Test strip,from whom urine samples within 8 hours during the nighttime were also collected.Both the two urine samples were determined by three assays for detection of microalbuminuria.Results(1)The value of Alb and AER determined by radioimmunoassy was significantly lower than that by DCA2000 analyzer,of which the sensitivity and specificity is 100%and 86.2%,?=0.812.(2)According to the reading scales of Micral-Test strip,the area under ROC curve(AUC)of random and 8 h urine samples were 0.900 and 0.934 respectively.(3)The AUC of random ACR and Alb was 0.952 and 0.923.The AUC of 8h urine ACR and Alb were 0.965 and 0.958.Conclusion The diagnosis importance among three assays is all dependable.Micral-Test strip is convenient for screening.ACR cannot substitute for AER as a diagnosis standard.And the value determined by DCA 2000 analyzer is more precise than that of radioimmunoassay.

The vest mainly consists of thermogenic inner-bag and temperature control out-bag.Put the thermogenic reagent which main composition is metal-powder like iron and aluminium into inner-bag,and takes oxid- ation reduction reaction when meets oxygen in the air,and release the heat quality,The temperature is controlled dy the openness of out-bag. It is suitable for field operator and sufferer with backache end abdomenache.

Objective To summarize the main early complications after pancreatoduodenectomy and analysis of the probable causes.Methods The clinical data of 576 cases who underwent pancreatoduodenectomy(PD) in our department between Feb 1990 and May 2009 were analysed retrospectively.Results There were 92 early postoperative complications occurred in 85 patients(14.8%).Gastrointestinal dysfunction,pancreatic leakage,intra-abdominal infections and hemorrhage were the most of complications,and 7 cases died during perioperative period(mortality 1.22%),among which 3 died of multiple system organ failure,2 died of hemorrhagic shock and 2 died of toxic shock.Preoperative hypoproteinemia and hyperbilirubinemia complicated with a high incidence of postoperative complications on multivariate analysis.Conclusions Meticulous preoperative preparation,delicate intraoperative technigne and close postoperative observation are the key points to decrease early complications and improve the prognosis of the patients who undergo PD.
