Objective To develop the clinical application and the method for functional repair in fa- cial nerve defect in parotideetomy of parotid carainoma.Methods Defect of facial nerve in parotidectomy was repaired by transplantation of sternocleidomastoid muscle-great auricular nerve flap with anastomosis of great auricular nerve-facial nerve under microscope.Results Eight eases of facial nerve defect in parotid carcinoma were repaired by this method.The facial nerve function almost recovered and access to normal dur- ing 3 to 6 month after operation in this series.6 of 8 patients achieved a gradeⅡ,2 of 8 patients achieved a gradeⅢ.Conclusion Reconstruction of facial nerve defect using sternocleidomastoid muscle-great auricu- lar nerve flap can provide better blood supply for the plerosis and regeneration of nerve.The nerve flap also ac- celerate the functional recovery after nerve grafting.

PurposeSpinal cord is one of the most frequently involved sites of multiple sclerosis (MS), which seriously affects the life quality of patients. In this paper, we investigate the application value of voxel-based morphology (VBM) and resting-state magnetic resonance imaging (RS-fMRI) in multiple sclerosis patients with single spinal cord involvement (MS-SSCI).Materials and Methods Three-dimensional T1WI data and RS-fMRI data were acquired from 20 patients with MS-SSCI and 20 normal controls, grey matter volume (GMV), changes of white matter volume (WMV), total intracranial volume (TIV) and local nuclei volume were compared between the two groups using VBM, posterior cingulate cortex (PCC) was regarded as the seed point and the functional connectivity about whole brain was compared between the two groups by using resting-state functional connectivity analysis, the relationships between MS-SSCI structure, function change parameters and expanded disability states scale (EDSS) scores were further explored.Results①Compared with the control group, GMV, WMV, TIV of MS-SSCI group were not significantly reduced, only the volume of some regions (bilateral middle temporal gyrus, left inferior temporal gyrus) showed significant atrophy (P<0.01); MS-SSCI exhibited increased functional connectivity (FC) in the left medial prefrontal cortex, left inferior temporal gyrus, left caudate nucleus and right supplementary motor area (two-sample t test, after AlphaSim correction,P<0.01, voxel size >40).②There was no significant correlation (P>0.05) between MS-SSCI structure change parameters and EDSS; while a significant correlation between EDSS scores and FC was noted in the left inferior temporal gyrus (r=0.633,P<0.05).Conclusion Both structural abnormalities and altered FC with PCC can be detected in MS-SSCI, but only functional parameters are associated with clinical abnormalities, which are more sensitive than microstructural changes.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

Objective To clarify the relation between the expression of Foxp3 in peripheral blood and plasma transforming growth factor betal (TGF-β1) and the activity of systemic lupus erythematosus (SLE). Methods Foxp3 mRNA expression of 28 active SLE patients, 13 inactive SLE patients and 16 healthy controls was determined by polymerase chain reaction. Active SLE patients were followed up; Foxp3 mRNA expression of 20 active patients was measured in the stable status and the plasma TGF-β1 was measured by ELISA in the active and stable status. Results The active SLE patients showed reduced levels of Foxp3 mRNA than the inactive SLE patients (P<0.01) and the healthy controls(P<0.01). Expression of Foxp3 mRNA and the plasma level of TGF-β1 in 20 SLE patients were both higher in stable status than in active status, Conclusion The expressions of Foxp3 mRNA in peripheral blood and TGF-β1 in plasma has significant inverse corelation with disease activity, which suggests that regulatory T cells may play an important role in the pathogenesis of SLE.
