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.

Objective To compare the effects on neurobiological factors of attributional retraining group therapy (ARGT) or selective serotonin reuptake inhibitors (SSRI) for major depressive disorder (MDD),anxiety disorder (AD) and obsessive-compulsive disorder (OCD).Methods Outpatients with MDD,AD and OCD were divided into ARGT group (n =63) and SSRI group (n =66) according to the sequence of entering the study.MDD,AD and OCD patients were respectively measured with Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) before and after 8 weeks treatment.All subjects were detected of plasma serotonin,norepinephrine,cortisol and adrenocorticotropic hormone by radioimmunoassay before and after treatment.Results After treatment,HAMD scores of MDD patients were reduced significantly in both ARGT group (t =18.411,P =0.000) and SSRI group (t =20.092,P =0.000) ; HAMA scores of GAD patients were reduced significantly in both ARGT group (t =13.989,P=0.000) and SSRI group (t=15.815,P=0.000) ;Y-BOCS scores of OCD patients were reduced significantly in both ARGT group (t =5.465,P =0.000)and SSRI group (t =4.792,P =0.000).In ARGT group,MDD (t =3.145,P =0.006),AD (t =2.785,P =0.012) and OCD patients (t =2.877,P =0.011) decreased plasma cortisol concentrations significantly.In SSRI group,MDD (t =-2.923,P =0.010) and OCD patients (t =-2.301,P =0.035) improved plasma serotonin significantly and MDD patients (t =-2.333,P =0.033) improved plasma norepinephrine significantly.Conclusion ARGT can modulate plasma cortisol level.SSRI can up-modulate plasma serotonin level.The two therapies take effect by different biological ways.

Objective To investigate the inhibitory effect of paclitaxel on rat graft arteriosclero- sis and the mechanism.Methods The rat abdominal aortic allograft model was used.All rats were divided into three groups:isograft control group (Wistar to Wistar),allograft group (Wistar to SD) and allograft paclitaxel-treated group (Wistar to SD).Rats in allograft paclitaxel-treated group re- ceived paclitaxel (2 mg?kg~(-1)?d~(-1)) from the operation day to post-operative day 14 and others received same dosage of vehicle (0.9% normal saline).Animals were sacrificed and the grafts were harvested at 30th day after operation.Intimal proliferation was studied by light microscopy.The apoptosis of vascular smooth muscle cells (VSMCs) was detected by transmission electronic microscopy and termi- nal deoxynucleotidyl transferase biotin nick end-labeling (TUNEL) method.Results Morphological analysis showed that grafts had no change after operation in isograft control group,but in allograft group intimal proliferation,inflammatory cells infiltration in neointima and adventitia and stenosis of allografts were obvious.After treatment with paclitaxel,there was a significant decrease in intimal proliferation,inflammatory cells infiltration and stenosis.Apoptosis index of VSMCs was higher in the allograft paclitaxel-treated group than other groups.Conclusion Paclitaxel can inhibit intimal pro- liferation in aortic allografts and prevent the graft from arteriosclerosis possibly by inducing the apoptosis of VSMCs.

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.
