Objective: To study the application of CT and MRI fusion technique in the diagnosis and treatment of intraocular and orbital tumors. Methods: 2D-images of 13 patients with intraocular and orbital tumors were fused by special-point registration and Iterative Local Closest Point(ILCP) method; 3D-fusion images were reconstructed by Ray Tracing method. Results: A 3D-CT-MRI fusion images of intraocular and orbital tumors were reconstructed and displayed. The CT and MRI data of intraocular and orbital tumors were displayed on the same image as a comprehensive whole,which provided a stereogram of 3D-structure of the normal and abnormal orbital tissues. Anatomical structure of the orbit was clearly visualized by 3D-CT-MRI image. Conclusion: The multi-modality fusion technique can provide more accurate and comprehensive information for clinical diagnosis of intraocular and orbital tumors, which is helpful for doctors' planning of surgical operations,clinical education and doctor-patient communication.

Objective To investigate the risk factors of diabetic foot by observing the changes of the relative index. Methods 134 pa-tients were randomly divided into non-diabetic foot (NDF) group and diabetic foot (DF) group,the changes of blood glucose,HbA1c,creati-nine,uric acid,microalbuminuria and the complications of diabetes were observed. Results There no difference in blood glucose level be-tween 2 groups (P>0. 05). The HbA1c levels of DF group was higher,with a significant difference(P<0. 05). The levels of uric acid in fe-male of DF group was higher than those in female of NDF group(P<0. 05). there was significant differernces in levels of microalbuminuria (P<0. 05),but no statistic difference in levels of potassium and sodium between 2 groups. Conclusion The changes of HbA1c,uric acid and microalbuminuria could indicate the diabetic foot in clinic.

Objective To observe the impact of DPP4 inhibitor Saxagliptin on body weight of type 2 diabetes patients. Methods In this randomized and parallel study,50 patients were given either Saxagliptin(n=25)or Glimepiride(n=24). The changes of body weight, HbA1c and hypoglycemic events were observated in 12 weeks. Results There were no significant difference in gender,age and body weight between 2 groups(P>0. 05). After 12 weeks treatment,body weight has significant changed in both group,and the weight changes were sig-nificant differet in two groups:an average of 0. 4 kg weight was increased in Glimepiride group and 0. 4 kg weight was decreased in Saxagliptin group (P<0. 05). The change of HbA1c level has no statistical difference in two groups (P>0. 05). Hypoglycemia event was happened four times in Glimepiride group,while no hypoglycemia event was happened in Saxagliptin group. Conclusion Compared with Glimepiride,Saxa-gliptin provides similar hypoglycemic action with less hypoglycemia,at the same time,Saxagliptin yields better results in lowering weight.
