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.

Epstein-Barr virus (EBV) infection is associated with some autoimmune diseases. We report here a 32 months old girl with fever, isthmitis, lymphadenectasis, and excessive atypical lymphocytes, who developed seizures, personality and behavior changes, with positive anti-N-methyl-D-aspartate receptor (anti-NMDAR) antibody and EBV-early antigen (EA)-IgG antibody in cerebrospinal fluid (CSF), which suggested the possibility that the acute EBV infection have triggered the anti-NMDAR encephalitis, which has not been reported previously.

Objective To investigate the effects of p-cresol on human umbilical vein endothelial cells.Methods The effects of p-cresol on endothelial cell growth,cell cycle,cell morphological change and p21 protein were detected by the CCK-8 assay,flow cytometry assay,inverted microscope and Western blotting.Results P-cresol could inhibit the growth of human umbilical vein endothelial cells in dose-and time-dependent manners (all P ＜ 0.05).The human umbilical vein endothelial cells treated with p-cresol became elongated processes,cloudy cytoplasm,and irregular shapes.The p-cresol stopped human umbilical vein endothelial cells at cell cycle G1 and had no effect on cell apoptosis.The p-cresol could increase protein expression of p21 in a dose dependent manner (P ＜ 0.05).Conclusion P-cresol can increase protein expression of p21,induce cell cycle arrest at G1 stage and inhibit the proliferation of human umbilical vein endothelial cells.
