Objective To determine whether pancreatic ductal preservation(pancreatic ductal injection of sparing TIUW solution at the time of pancreas procurement)can improve islet yield and function after cold preservation of pancreas.Methods Pancreases were classified into five groups:fresh pancreases(group1 ,n= 10);preserved for 6 hr in TIUW solution without and with pancreatic ductal preservation by TIUW solution(group2, n=10 and group3, n = 10);preserved for 24 hr in TIUW solution without and with pancreatic ductal preservation by TIUW solution(group4 ,n= 10 and group5,n= 10).Dithizon(DTZ)staining was used to identify islet morphous and yield, trypan blue uptake(TBU)was used to assess the nonviability of islets, the insulin secretory response to glucose was used to evaluate islet function in vitro, islet transplantation was used to determine islet function in vivo.Results Islet yields per pancreas after purification in group 1 to 5 were 590± 127, 272 ± 50,454 ± 65, 253± 56, 447 ± 66(islet equivalent ± SD), respectively.Percentage of nonviable islets in grouplto5were(5.7±4.2)%,(18.3±6.5)%,(11.7±4.2)%,(26.3±5.6)%,(15.0±5.3)%.Stimulation index in group 1 to 5 were 7.32±2.32, 4.81±1.17, 7.56±2.44, 2.88±1.00, 5.71±1.90.Cure rates in group 1 to 5 were 100%, 0%, 100%, 0%, 70%.In this study, the differences were significant between control groups and experimental groups(P＜0.05, group 2 vs.group3 and group4 vs.group5).Conclusion The pancreatic ductal preservation can improve islet yield and function.

The development of liver surgery can be divided into several stages, including wedge liver resection, regular segmental liver resection and anatomical liver resection. With the development of biomedical sciences and information technology, liver surgery has developed into precise hepatectomy. The goals of precise hepatectomy are minimal invasion, maximal liver protection and best rehabilitation, This is mainly achieved through accurate preoperative evaluation, precise surgical planning, sophisticated surgical procedure and postoperative management. Its application significantly improves prognosis and quality of life of patients. This paper summarizes the concept and surgical technique of precise liver resection.

Objective To explore the value of T wave alternans (TWA) in prediction ventricular arrhythmias in post-op TOF children. Methods The characteristics of TWA were retrospectively analyzed in 36 post-op TOF patients and 120 age-matched normal children. The relationship of sustained TWA and ventricular arrhythmias was also analysed. Results Compared with normal children, the incidence of sustained TWA was significantly increased in post-op TOF group (χ2=6.98, P<0.05). In post-op TOF patients, the incidence of ventricular arrhythmia was much higher when sustained TWA was present (χ2=10.41, P<0.05). Conclusions There exists electrophysiological basis for ventricular arrhythmia in post-op TOF children. Sustained TWA has important value in prediction of ventricular arrhythmia of post-op TOF.

A novel strategy employing dendrimer to multi-label the template molecule to improve the sensitivity of molecularly imprinted electrochemical sensor was proposed. The determination relies on a competition reaction between poly ( diethylene-triaminepenta-acetic acid )-glycol ester ( PDTPA )-ferrocene-carboxylic acid ( FcA ) labeled gibberellins acid 3 ( GA3 ) and GA3 in the sample. Since one cavity corresponds with multiple FcA, instead of only one FcA, the intensity of the detecting signal was greatly enhanced, so was the sensitivity of the sensor. Experimental results showed that the molecularly imprinted electrochemical sensor was sensitive to GA3 detection at a concentration from 2. 0í10-9 to 1. 0í10-7 mol/L, with a detection limit of 9. 3í10-10 mol/L. In addition, the sensor had good reproducibility and its feasibility was verified in the analysis of series of real beer samples.
