There was no perforation and bleeding,but hyperamylasemia occurred in 3 patients and acute pancreatitis occurred in 1 patient and bile perito-nitis occurred in 2 patients.Conclusion Percutaneous transhepatic various interventional technique can keep the function of papillary sphincter and is a valuable methed for patients suffering from common bile duct stones with a high successful rate and safety.

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3～5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

Objective To evaluate the reproducibility of normal liver ADC measurements by different respiratory motion compensation techniques. Methods A total of 31 young healthy volunteers who are 20 to 40 years old without any hepatic diseases were selected to research. Each volunteer underwent liver DWI twice in 24 hours with the same parameters and location. The imaging was performed with free-breath(FB), breathhold(BH), rspiratory-triggered(RT)and navigator-triggered(NT)techniques, and the ADC values of the left hepatic lobe and right hepatic lobe (upper, middle and lower) was acquired with two scans. Analysis the the ADC values of various anatomic locations of liver with two-way analysis of variance of randomized block design. Reproducibility of ADCs was assessed with the Bland-Altman method. Analysis of variance and paired-sample t test was used to assess ADCs from both right and left liver lobe among the four techniques. Result The ADC values acquired from the four techniques were significant differences (P<0.01),and the ADC values of the right lobe were less than the left lobe's(P<0.01). It showed a trend to decrease moving from superior to inferior levels in both left and right lobes, and the ADC values among The middle and lower were significant differences (P<0.01). The limit of agreement of ADC of twice imaging among the four techniques were as follow: the right lobe was less than the left lobes, and the breathhold was less the others. As the result, reproducibility in the right liver lobe was better to that in the left and the reproducibility with breathhold was better than the other respiratory motion compensation techniques. Conclusions Both anatomic location and DWI technique influence the liver ADC measurements and their reproducibility. The reproducibility of BH is the best.
