Objective: To identify the optimal rotation time and pitch of 64-slice spiral CT angiography for arterial occlusive diseases (AOD) of the lower limbs. Methods: We performed test-bolus in eighty patients with AOD of the lower limbs (48 with intermittent claudication and 32 with ischemic rest pain or ulceration) to confirm the aortic peak time, popliteal artery peak time and aortopopliteal bolus transit time. The patients were randomly assigned to receive two sets of scan protocols for lower limb arterial 64-slice spiral CT angiography (CTA) examination (n = 40), protocol A, with a gantry rotation time of 330 ms and a pitch of 1.0; protocol B, with a gantry rotation time of 500 ms and a pitch of 0. 85. Two experienced radiologists independently evaluated the image quality of the lower limb artery. Results: Great differences in the time to peak enhancement in the aorta (14-33 s) and popliteal arteries (20-48 s) and the aortopopliteal bolus transit time (4-24 s) were found between different AOD patients. Wide overlap of the time to peak enhancement and transit time was observed between intermittent claudication patients and ischemic rest pain or ulceration patients. The qualities of segment images were rated as excellent 63.3% (152/240), good 30.0% (72/240), and poor 30.0% (72/240) for protocol A, and excellent 98. 3% (234/238) and good 1. 7% (4/238) for protocol B, with no poor images in protocol B. Conclusion: 64-slice CTA with a gantry rotation time of 500 ms, a pitch of 0. 85, scan time>30 s, and with the contrast agent injection time maintained at 35 s, can obtain better image of lower limb arteries in patients with AOD of the lower limbs.

Objective To evaluate the clinical effectiveness of the combined use of S1 pedicle screws and the iliac screws in treatment of sacroiliac dislocation and fracture. Methods 11 patients with sacroiliac dislocation and fracture were treated with S1 pedicle screw and iliac screw fixation technique. In this group, the dislocation was associated with vertical displacement of the sacroiliac joint and rotational deformity of the pelvic ring. They were classified as type B or type C pelvic disruption according to the Tile's classification. 7 patients with disruption of the symphysis pubis or pubic branch fracture underwent additional fixation of the pelvic ring using a reconstruction plate. The remaining 4 patients were treated by the posterior procedure alone. Results The vertical displacement was completely reduced in 7 patients, and the rotational deformity completely corrected in 4 patients. The reduction was maintained at the time of final follow up evaluation. No perioperative complications were found. The combined use of S1 pedicle screws and the iliac screws provided immediate stability and sufficient reduction for sacroiliac dislocation in the 11 patients in this study. Conclusion This hybrid internal fixation procedure is useful for reduction and fixation of sacroiliac dislocation associated with the vertical and rotational instability of the pelvic ring.

Anaerobic ammonium oxidation(ANAMMOX)is a new process of nitrogen conversion that has prospect most currently.The AN- AMMOX process offers great opportunities to remove ammonia from wastewater without the addition of an external carbon source and with con- siderable less aeration costs in comparison with classical methods.ANAMMOX is a biologically mediated process.Three bacteria are identi- fied responsible for the process as new deep-branching planctomycete:Brocadia,Kuenenia and Scalindua.Described it to separate and the method,biochemistry path,the ecosystem physiology characteristic for authenticate and distribute.

The purpose of the National Competition in Basic Medicine Innovation Forum & Ex-perimental Design in colleges is to boost Excellent-doctor Education Training Plan, cultivating students' scientific research ability and other comprehensive capacity. In practice, the originality and the scientific nature of the selected topic were emphasized through the provision of scientific research funding. The teachers changed their traditional instructional concept and teaching models. They guided the students to select the scientific subjects and took various measures to change students ' learning mode, resulting in gradually pro-moting the students' scientific research level and comprehensive ability. The results showed that these novel strategies are feasible and effective, which may provide a new way for improvement of the excellent doctor program.

Objective To evaluate the utility of three-dimensional digital subtraction angiography(3D-DSA) in the diagnosis of cerebral vascular diseases.Methods Seventy-one patients suspected and diagnosed with cerebral vascular diseases underwent conventional DSA and 3D-DSA. Three-dimensional (3-D) reconstructed images were obtained at a separate advantage 4.0 workstation after the rotational images were transferred. The available visualization techniques included maximum intensity projection (MIP), shaded surface display (SSD), and virtual angioscopy (VA). Results Sixty-four aneurysms were found in 44 cases. Nineteen cases were diagnosed as cerebral arteriovenous malformation (AVM) and 8 cases of cerebral ischemia were due to cerebral vascular stenosis (internal carotid artery in 6 cases and occlusion of anterior cerebral artery in 2 cases).Conclusions 3D-DSA is reliable, fast and safe for diagnosis of cerebral vascular diseases, especially involving intracanal areurysms AVM and vascular stenosis.
