During the recent conflicts in Iraq and Afghanistan,traumatic brain injury (TBI)has become the most prev-alent military injury that is described as the signature injuryof the current military operations.It usually causes no or mild external injury but results in serious long-lasting neuropsychiatric abnormalities,which have far-reaching impact on veterans,their families and the American society.Here we describeol the investment in TBI from the US government and the development in the diagnosis and treatment of mild TBI on the battlefield before putting forward some proposals for the Chinese army.

Objective To explore the diagnosis and treatment of upper limb trauma fracture complicated with deep vein thrombosis ( DVT) during preoperative period. Methods The data of 16 patients with upper limb trauma fractures complicated with DVT was analyzed retrospectively. The methods of diagnosis included color Doppler ultrasonography,multi slice CT angiography ( CTA) ,artery and vein visual-ization of upper limbs,and D-dimer detection. The treatment was majored in thrombolysis by urokinase and anticoagulation by low molecular heparin. Results There were 14 patients with increased levels of D-dimer,8 patients diagnosed by color Doppler ultrasonography,3 patients diagnosed by CTA and 5 by artery and vein visualization. The DVT of 5 patients before operation were disappeared after treatment and cured. Among the 10 patients received operation,8 cases were succeeded and 2 cases complicated with pulmonary embolism,and 1 case was died. Conclusion The color Doppler ultrasonography is the first priority for diagnosis of upper limb trauma fracture complicated with DVT. The patients should be discovered in time and arranged thrombolysis and anticoagulation in early time.
