OBJECTIVETo study the therapeutical effects of crossing anastomosis of nerve on the peripheral and central nerve injuries.

METHODSTwelve kinds of central and peripheral nerve disorders and their complications were treated with 11 kinds of crossing anastomosis of nerve bundles near the innervated organs. After nerve injury and repair, somatosensory evoked potentials (SEPs) and horseradish peroxidase (HRP) retrograde tracing studies were used to investigate the rabbit's nerve function and morphology.

RESULTSThe ulcers of all patients healed. Sensation, voluntary movement, and joint function recovered. Four weeks after the anastomosis of distal stump of radialis superficialis nerve and median nerve, pain sensation regained and SEPs appeared. HRP retrograde tracing studies demonstrated sensory nerve ending of medial nerve formed new connection with the body of neuron.

CONCLUSIONCrossing anastomosis of nerve is an effective method to treat peripheral and central nerve injuries.

OBJECTIVE: To investigate the relationship among perceived stress,sleep and fatigue status; and to analyze the effect of sleep status in mediating and regulating perceived stress and fatigue status in soldiers that were acutely exposed to high altitude for the first time. METHODS: A total of 700 soldiers that were acutely exposed to high altitude for the first time were investigated with convenient sampling. They were evaluated using Perceived Stress Scale,Sleep Status Self-evaluation Test,and Fatigue Scale-14. The mediating effect was analyzed by structural equation model,and the moderating effect was analyzed by hierarchical regression analysis. RESULTS: The total score of fatigue among soldiers that often took part in recreational activities was significant lower than that who did not( P < 0. 01). The total score of fatigue among soldiers that had training injury was significant higher than that who had not( P < 0. 01). The total score of fatigue among soldiers that had high training expectations was significant higher than that that didn't have high training expectations( P < 0. 01). Sleep status,sense of overload and training expectations had remarkable predicting effect on fatigue status among soldiers that were acutely exposed to high altitude for the first time( P < 0. 01). Sleeping status has a complete mediating effect on the sense of prediction,sense of overload and fatigue status( P < 0. 01),and has a moderating effect on the sense of control,sense of overload and fatigue status( P < 0. 01). CONCLUSION:s Perceived stress and sleeping status had close relationship with fatigue status among soldiers that were acute exposed to high altitude for the first time. Sleeping status has intermediary and regulating effect between senses of overload and fatigue state.
