Objective To observe the effect of superficial radial nerve transplanting to repair musculospiral nerve defection and using end-to-side neurorrhaphy to reconstruct the function of the donor site. Methods Thirtyfour cases underwent superficial radial nerve transplanting to repair musculospiral nerve defection and end-to-side neurorrhaphy was performed to reconstruct the function of the donor site. Results All cases were followed-up for 6 to 18 months,the functional recovery of the recipient of musculospiral nerve was excellent in 23 cases and good in 5 cases,with an excellent and good rate of 82. 53 %. Sensory recovery of donator nerve was excellent in 27 cases and good in 5 cases,with an excellent and good rate of 94. 12%. Conclusions Superficial radial nerve transplanting to repair musculospiral nerve defection and functional reconstruction of donor site is a better choice in treating neurologic defect.

ObjectiveTo summarize the method and experience of the model of rat heterotopic heart transplantation and to improve the rate of success of the experiment.Methods120 heterotopic heart transplantations were performed by Ono's way,including 60 prepared transplantations and 60 formal transplantations.ResultsRate of success of prepared transplantations was 45％,and formal transplantation was 85％.Mean time of formal operation was (74.3±17.1)min,removal time of the donor heart was (7.9±4.2)min,ischemia time was (29.6±10.3) min and the survival time of allograft was (11.1±5.7)days.5 of the recipients had a long-term survival,and the maximum weight was 740 g.ConclusionsGood surgical technique and rigorous perioperative management is very important in setting up the rat model of heterotopic heart transplantation.
