Seeking the optimum kinds and quantity of excipients. Results : The best properties of the granules are from the spray drying process. ?-cyclodextrin and lactose have the effects on solving the powder sticking on the wall. Conclusion : The spray drying process is the optimum one. Adding 3～5 percent of ?-cyclodextrin has an effect on improving the phenomenon of powder sticking on the wall in process of the spray drying.

Objective To summarize the experience of reconstruction of Ⅴ and Ⅷ hepatic veins in right lobe (without middle hepatic vein) living donor liver transplantation. Methods The clinical data of 55 cases of living donor liver transplantation of right lobe without middle hepatic vein were analyzed, and Ⅴ and Ⅷ hepatic veins were reconstructed. All donors underwent evaluation on the basis of vascular anatomy, GRWR and graft volume/ESLV. Fifty-one grafts underwent reconstruction of Ⅴ and Ⅷ hepatic veins with cold-storage cadaveric iliac veins. Great saphenous vein, varicose umbilical veins, recipient intrahepatic portal veins and recipient intrahepatic veins were used respectively in the remaining 4 cases. Results One recipient died of obstruction of out-flow on the postoperative day 43. One recipient was converted to cadaver donor liver transplantation at the 7th day after operation, because of acute liver function failure. The remaining 53 cases recovered successfully. Conclusion Reconstruction of Ⅴ and Ⅷ hepatic veins with proper materials in right lobe (without middle hepatic vein) living donor liver transplantation is feasible, and the effect is satisfactory.
