目的 观察犬去细胞异体神经移植后近期神经再生的情况。谅15只家犬分成实验组（去细胞神经移植组，6只犬），对照组I（自体神经移植组，6只犬），对照组Ⅱ（新鲜异体神经移植组，3只犬），制成犬坐骨神经缺损5.0cm的模型，以上述3种神经移植物桥接修复。术后6个月行神经再生的组织学观察。结果 实验组移植段内有大量的新生神经纤维，新生血管及雪旺细胞；远端胫神经内出现大量的有髓神经纤维；靶肌肉运动终板的数量，形态及分布均良好。实验组和对照组I非常相似。结论 化学去细胞神经作为同种异体神经移植物，在修复术的粗大和长段神经缺损时不会被宿主排斥和吸收，其神经再生与自体神经移植无明显差别。     

Nerve transfer for treatment of brachial plexus injury：comparison study between the transfer of partial median and ulnar nerves and that of phrenic and spinal accessary nerves

Objective:To compare the effect of using partial median and ulnar nerves for treatment of C5-6 orC5-7 avulsion of the brachial plexus with that of using phrenic and spinal accessary nerves.Methods:The patients were divided into 2groups randomly according to different surgical procedures.Twelve cases were involved in the first group.The phrenic nerve was transferred to the musculocutaneous nerve or through a sural nerve graft,and the spinal accessary nerve was to the suprascapular nerve.Eleven cases were classified into the second group.A part of the fascicles of median nerve was transferred to be coapted with the motor fascicle of musculocutaneous nerve and a part of fascicles of ulnar nerve was transferred to the axillary nerve.The cases were followed up from 1to 3years and the clinical outcome was compared between the two groups.     

Latissimus dorsi transfer for primary treatment of irreparable rotator cuff tears

Transfer of the musculotendinous unit of the latissimus dorsi was performed in seven patients (5 men and 2 women, with a mean age of 57 years) with irreparable rotator cuff tear who had had no previous surgery for cuff repair. Preoperatively, the mean active shoulder motion was 86° in flexion, 74° in abduction and 22° in external rotation. One patient had a positive lift-off test. The average preoperative Constant and Murley score was 44%. Diagnosis of irreparability of the cuff leasion was made preoperatively only in one case. In the remaining patients, the preoperative data only led to suspect that the tear was irreparable. At surgery, all patients had an irreparable tear of the superoinferior portion of the cuff and one patient also had a tear of the subscapularis tendon. In all cases the latissimus dorsi tendon was inserted to the greater tuberosity and, in four cases, to the subscapularis tendon; in three patients it was sutured to the bicipital tendon. Postoperatively all patients had relief of shoulder pain. The mean improvement in active flexion, abduction and external rotation was, respectively, 39°, 29° and 10°: At the latest follow-up, the average Constant and Murley score was 64%. The results of surgery were rated as excellent in three cases, good in two, fair in one and poor in one. All patients but one returned to preoperative work. Transfer of the latissimus dorsi muscle is an effective procedure for patients in middle or early elderly age who have an irreparable tear of the supraspinatus and infraspinatus tendons.
