Objective To study on diagnosis and treatment of brain type fat embolism syndrome complicated with fracture. Method The diagnosis and treatment of 7 cases of brain type fat embolism syndrome complicated with fracture were reviewed. All of 7 cases did not have any brain injury, 3 cases were complicated with femural fracture, 3 cases with fractures of tibia and fibula, and 1 cases with limbs multi fracture. They presented somnolence or coma complicated with rise in temperature (37.7℃～39℃) ,increase in breath and heart rate,anemia,small bleeding spots at chest. It was discussed how to distinguish brain type fat embolism syndrome from brain injury. Synthetical measure was adopted mainly using dexamethasone (20～80mg/d). Results 7 cases of brain type fat embolism syndrome complicated with fracture were cured in 1～7 days. Conclusions Sudden somnolence or coma that does not result from brain injure after limb fracturees in early stage can be diagnosed as brain type fat embolism syndrome. A synthetical measure should be adopted by mainly using dexamethasone (40～80mg/d) .

Objective To study the mechanism, pathology and treatment of the lung injury after spinal cord injury. Methods Models of spinal cord injury were made with modified Allen methods in 40 rabbits and divided into Group A (control group) and Group B (experimental group). Group B was treated with dexamethasone (0.35mg/k/d) by intravenous drip at first 3 days. The rabbits of spinal cord injury were killed for autopsy at different time points and their lungs were observed pathologically. Results Different degrees of lung injury, with hemorrhage of lung (100 %), occurred after spinal cord injury. The hemorrhage of lung in Group B which received the administration of dexamethasone was obviously slighter than that in Group A (P
