Objective To report the clinical effects of repairing skin defects in hand by reversed neu- ro-veno-fasciocutaneous flaps based on the superficial branches of radial nerve.Methods Eleven cases with soft tissue defects around the wrist and the dorsum of the hand were treated with superficial branches of radial nerve-cephalic vein neuro-veno-fasciocutaneous flaps.Results The flaps totally survived in the 9 cases,the others were small distal necrosis.Follow-up survey in the(6-48)months after the oporation showed the appear- ante and function were satisfactory.Conclusion Superficial branches of radial nerve neurofasciocutaneous flap is well supplied with blood and easy to perform.It is the ideal flap to repair the skin defects of the first finger web,radial palm and dorsum of hand.

Objective To investigate the specific CT findings of gastrointestinal stromal tumors (GIST).Methods The CT imaging of 12 cases of GISTs confirmed operatively and pathologically were reviewed and analyzed.The gross pathologic findings of the tumors were compared with the manifestations of CT study.Results Two of the GIST were from the stomach,2 from the duodenum,4 from jejunum,and 1 from the junction of jejunum and ileum,ileum,rectum and mesenterium respectively.5 of 8 cases with GIST from intestine had history of hemafecia or positive of fecal occult blood test.9 of the 12 GISTs were malignant,1 of them was potentially malignant,1 was not sure to be malignant or benign.CT studies of 11 of the 12 tumors showed as exogenous mass of 3-20 cm,only 1 with less than 5 cm and 8 of them with over 5 cm.in the max diameter the tumors were cystic-solid with inhomogenous attenuation.The solid potion of tumors enhanced moderately to markedly after the contrast media administered.Ulcer was seen in the tumors of 2 cases,and the diameter of both of them were over 12 cm.Punctate calcification was seen in 1 GIST.Conclusion CT findings of GIST were specific to a certainty.CT study is helpful for locating the tumor and observation of the relationship of the tumor and surrounding structures.

Objective To investigated the expression of intracellular adhesion molecule-1 (ICAM-1)in mouse to rat cardiac xenograft and the effects of leflunomide and cyclosporine.Methods NIH mice and Wistar rats served as donors and recipients respectively.Mouse to rat heterotopic heart transplantation was performed(in the neck).The experiments were divided into 4 groups:CsA group,leflunomide(Lef)group,CsA+Lef group,control group.It was the time of rejection that no pulsation could be detected in the transplanted heart.The expression of ICAM-1 protein in cardiac xenograft tissue was detected by immunohistochemistry and Western blot in each group.Results The survival time of cardiac xenograft in control group,CsA group,Lef group and CsA+Lef group was (2.17?0.41),(2.50?1.05),(4.17?1.33)and(6.50?2.56)days respectively.The expression of ICAM-1 protein(IOD)in cardiac xenograft tissue in control group,CsA group,Lef group and CsA+ Lef group was 155.40?5.33,150.73?5.13,104.65?6.15 and 29.24?2.76 respectively.Conclu- sion The expression of ICAM-1 protein was strong in mouse to rat cardiac xenograft.The combined use of Lef and CsA can significantly suppress the expression of ICAM-1 protein in the cardiac xenograft.
