Results The earlier period of 5 cases remained defect as the pedicle relatively short and thick, healed through change of dressings.One case was partially torn for the deficient of fixation,and healed after refixation.One case's recipient skin graft necrosed because of long duration of compression and recovered after the second time skin graft.

Result The results showed that tissue culture seedlings cultured with disinfection seeds and fresh fruit seeds had higher survival rates, which could reached above 75.0%. Taken Pingguoli and Xiangshuili for cions, Shanli without root for rootstock, the survival rate of graft seedlings had obvious difference. And Xiangshuili for cions had higher survival rates. Taken Xiangshuili for cions, Shanli and Xiangshuili for rootstock, the survival rate of graft seedlings with root had higher survival rates than that without root. Added hormone to the media could improve the survival rate of micro-grafting plants, in the medium of MS+BA 1.0 mg/L+IBA 0.3 mg/L, the survival rate reached 86.7%.

结果］种子消毒处理及鲜果取种组培苗的成活率均较高，达75.0%以上；以香水梨和苹果梨为接穗，无根山梨为砧木时的嫁接苗成活率有显著差异，其中以香水梨为接穗的成活率较高；以香水梨为接穗，山梨和香水梨为砧木时，带根的材料嫁接时的成活率都显著高于无根嫁接苗的成活率；此外，添加植物生长调节物质可以有效提高嫁接成活率，在培养基MS+BA 1.0 mg/L+IBA 0.3 mg/L中嫁接苗的成活率最高，达86.7%。

Basing on the setup of animal model of root avulsion of the brachial plexus, we divided the experimental animal into four groups by the operative method: Group A: one end of the maternal nerve graft was connected with the upper trunk of the healthy side by end-to-side neurorrhaphy, and the other end was sutured to the distal stump of musculocutaneous nerve infraclevicularly by end-to-end neurorrhaphy. Goup B: on the healthy side, the operation was the same, the other end was sutured to the distal end of C〓 by end-to-end neurorrhaphy on the affected side. Group C: the maternal nerve graft bridged the phrenic nerve and infraclevicular musculocutaneous nerve of the affected side by end-to-end neurorrhaphy. Group D: the phrenic nerve was sutured to the distal end of C〓 supraclevicularly by end-to-end neurorrhaphy.
