Objective To investigate the application value of intraoperative ultrasound (IOUS) in living donor liver transplantation(LDLT). Methods In LDLT, IOUS techniques (gray scale ultrasound and color Doppler flow imaging) were adopted in 26 donors and recipients for parenchymal and vascular examinations. The abnormal sonograms were observed, and the anatomic findings of hepatic veins were recorded. All the reanastomosed blood vessels were examined by gray scale ultrasound and color Doppler flow imaging before the operations were completed. Results A hepatic parenchymatous tumor was revealed by IOUS in one donor. Besides, middle hepatic veins in 13 donors and secondary hepatic veins with diameter﹥0.5 cm in 5 donors were confirmed by IOUS. Furthermore, one operation procedure was changed and one hepatic artery stenosis was established according to IOUS findings. Conclusion IOUS is a very useful means in evaluation of parenchymal and vascular conditions of donors and recipients in LDLT, which helps to select the best cross section and provides evidence for the change of surgical procedures.

BACKGROUND:It is unclear whether serial cel passage in vitro influences the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s.
OBJECTIVE:To investigate the effect of cel passage on the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s.
METHODS:Rat bone marrow mesenchymal stem cel s were isolated and cultured by the whole bone marrow adherence method. Bone marrow mesenchymal stem cel s at passages 3, 6, 9, 12 were incubated in serum-free medium. After culture for 7 and 14 days, cel biological characterization was observed and differenitaiton ability into neural stem cel s was observed by detecting Nestin expression in cel s using flow cytometry. Then, the cel s were further induced to differentiate and cel multipotential differentiation capacity was detected by measurement of nerve enolase and glial acidic protein expression.
RESULTS AND CONCLUSION:Under induction, bone marrow mesenchymal stem cel s at different passages were al differentiated into Nestin-positive neural stem cel s. However, there was a significant difference in differentiation proportion of cel s at different passages (P<0.05). Strongest differentiation ability was found in the passage 6 cel s, with the Nestin expression up to (93.7±2.3)%at 7 days of induction and (96.2±1.8)%at 14 days of induction. The proportion of differentiated cel s at passages 6 and 9 was signfi cantly higher than that at passages 3 and 12. Moreover, adherent cel s were positive for nerve enolase and glial acidic protein. Al these findings indicate that the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s is correlated with cel passage. Cel s at lower or higher passages are both detrimental to cel differentiation.
