Objective Through dissection of the thoracodorsal nerve in 22 adult male corpses,to measure the length of thoracodorsal nerve and the length of displaced nerve need respectively in order to provide possible anatomical basis for treatment of deltoid muscle and axillary nerve.

Objective To discuss the significance of predicting the injury degree of the thoracodorsal nerve by intraoperative electrophysiological examination in the C7 nerve root transfer for brachial plexus injury patients.

Effect of pulsed radiofrequency treatment of the lumbosacral dorsal root on cytokines;

The release of SP and CA in the region deminated by dorsal root was examined by using the methods of cutting dorsal root, stimulating the distal end, dissociating the governed skin, collecting and determining the dermic perfusing liquid.
