Objective To explore the anatomy and the adjacent of the medial malleolus,the operative approach of soluting the tibial nerve in endoscopy and the significance of making use of it in operation. Methods The five cadaver feet were dissected,the tibial nerve and the fiber diaphragm in the middle of me- dial and lateral plantar tunnels in the ten cadaver feet were soluted in endoscopic.Results The operative approach was designed on the basis of the anatomy data (the three-portal approach:The perpendicular bisetor which was the medial malleolus pointed to the medial margin of tendon calcaneus insertion was 4.5cm;The midpoint of the medial malleolus pointed to the calcaneus tubercle;The midpoint of the calcaneus tubercle to the medial margin of the first metatarsophalangeal joint).It was succeed that soluted the tibial nerve and the fiber diaphragm in the middle of medial and lateral plantar tunnels.Conclusion The operative approach on the basis of the anatomy data is design,and testfy the feasibility of exploring curved tunnel in endoscopic.

Background The key premise of genetic research and treatment is to select the desired gene vector,ultrasound microbubbles as a new type of gene vector can safe,fast and effectively enhance the gene transfection and expression by reversibility increasing the permeability of cells. Objective This study was to observe the effects of ciliary neurotrophic factor(CNTF)gene mediated by ultrasound microbubbles intraocular transfer on visual function and retinal ganglion cell(BGCs)after optic nerve injury. Methods Fifty-five adult Sprague-Dawley(SD)rats were divided into 6 groups randomly,including normal control group(n=5),sham injury group(n=10),simple injury group(n=10),naked plasmid group(n=10),plasmid+ultrasonic irradiation group(n=10)and ultrasound microbubbles group(n=10).The model of optic nerve injury Was made by forceps clip on the fight optic nerve.and the corresponding intervene was performed in different groups.Flash visual evoked potential(F

Purpose To study the clinicopathologic features and differential diagnosis of primary mucosal melanoma of the nasal cavity (PMMNC).Methods 17 cases of PMMNC diagnosed from January 2003 to September 2016 were studied by clinical pathological analysis and immunohistochemical staining,and relevant literatures were reviewed.Results 73％ of the PMMNC was characterized by unilateral nasal congestion and intermittent epistaxis and 61％ of the PMMNC occurred in the nasal septum and nasal side wall.Microscopically,the organizational structure and morphology were complex and diverse,which had several cell types including epithelioid cell type (6cases,35.3％),spindle cell type (3 cases,17.6％) and snall cell type (5 cases,29.4％),the other 3 cases (17.6％)were mixed cell type.Mitotic activity and tumor necrosis were more likely to be seen in PMMNC,among other clinicopathological features with a small amount of fibrous stroma and melanoma and rich blood vessels.The immunohistochemical study showed that the positive rate of S-100 and HMB-45 were both 93.8％(15 cases) and those of Melan-A and vimentin were both 87.5％ (14 cases),while CK and EMA were both negative (16 cases).Conclusion PMMNC is a rare disease and the phenotype of S-100,HMB-45,Melan-A and vimentin are useful for diagnosis of PMMNC.
