Objective To probe imaging manifestations of bronchogenic cysts,as that to improve the knowledge of this disease.Methods Imaging features of congenital bronchial cyst in 32 cases confirmed by operation and pathology were analyzed.Results 4 cases of cyst localized in mediastinum ,all were liquid cyst.28 cases of cyst localized in lungs,aqmong them,22 cases were air-liquid cyst and 6 cases were air cyst,the diameter of lesions was 1~10 cm,there were 2 cases with pyothorax,4 cases with pulmonary maldevelopment,one case with brochio-pleural fistula.The cysts appeared as round or similar round,the walls of cyst was thin.The wall of cyst was obscure and there was infiltrating shadow around cysts when in company with infection.Conclusion X-ray and CT are very important in diagnosing congenital bronchial cysts,CT scan is of very help in diagnosing the compley cysts.

Objective To investigate the application value of spiral CT spinal cord and intervertebral disk 3D recontruction in vertebra trauma.Methods 78 patients with vertebra trauma were examined by CT axial, the primal date of each were retrospectively inserted and reconstructed, all the cases use 3D,SSD and sagittal MPR, compared with routine 2DCT.Results Spinal cord was normal in 23 cases.Spinal cord was pressed in 39 cases.Spinal cord was transected in 16 cases.Intervertebral disk was damaged in 38 cases.Conclusion Spiral CT can do spinal cord and intervertebral disk 3D reconstruction , it can show vertebra trauma and display intervertebral disk damage intuitionistically,which has instruction in making reasonable cure project and judging cure effect.

We have developed a new rotating bed for the old and the paralised people. This rotating bed is composed of two bed heads at front and at end, bed boards, guardrails, an electric motor, a reducer, an induction locator and a set of electronic controls. With the preestablished program, the angle between the left/right bed board and the middle board is changed by rotating the left/right board around the rotation axis, and the gravity direction between the human body and the ground is changed by the rotation of the middle board as a whole, so that the middle bed board and the left and right ones will act respectively as supporters of weight of the person who is lying on his back or on his side. In this way, a person can turn over automatically, comfortably and naturally when he/she is asleep. This rotating bed meets the physiological needs of a sleeping person, and people with turning over problems can turn over in a comfortable and natural way by means of biotechnology. It can also improve the quality of sleep and help avoid decubitus. In addition, it can be used to promote the rehabilitation of those who are paralysed by reason of its passive exercising function.
