Objective To investigate the MRI abnormalities and feature of FDG metabolism in the brain of patients with progressive supranuclear palsy.Methods Eleven patients with PSP and 178 patients with PD were prospectively studied with mid-sagittal plain MRI;five patients with PSP and 48 patients with PD were prospectively studied with 18F-FDG PET.Results The atrophy of the midbrain tegmentum and hummingbird sign were demonstrated in all of the PSP patients studied,but were not observed in PD patients.The area of the midbrain on mid-sagittal plain MRI in the patients with PSP was significantly smaller than that in those with PD.The patients with PSP had more prominent decrease of glucose metabolism symmetrically in frontal cortices and lentiform compared with PD.The lentiform in PD showed significant glucose hypermetabolism compared with thalamus.The regional glucose metabolism of PSP was symmetrical while that of PD was asymmetrical in lentiform and thalamus.Conclusion The assessment of the mid-sagittal plain MRI and 18F-FDG PET images may be a useful adjunct to a clinical examination when making a differential diagnosis of PSP with PD.

We reported a case of a work-related accident involving periorbital and intraorbital metal foreign bodies. The patient was a 43-year-old woman whose nasal dorsum was struck while she was sawing wood with nails. X-ray plain films of skull bone and computed tomographic scan of nasal sinus revealed two 5-mm-long metal objects lodged in right lacrimal sac and medial bulbar space of the right orbit. No deficits were noted in her visual acuities, visual fields, and ocular movements. Based on accurate positioning by imaging examination, transnasal endoscopic removal of metal foreign bodies was successfully accomplished. The patient recovered well without any complications after surgery.

Objective To compare the clinical efficacy of different surgical treatment on cholesteatoma otitis media and analy‐sis its differences .Methods Totally 100 cases of patients with cholesteatoma otitis media in hospital were divided into two groups , 50 cacse in each group ,the control group used open mastoidectomy for treatment ,the experimental group used complete bi‐style mastoidectomy ,and the postoperative clinical efficacy were observed .Results The experimental group patients after radical mas‐toidectomy complete bi‐style treatment ,air conduction hearing threshold (26 .89 ± 7 .23)dBHL and gas bone conduction (12 .54 ± 3 .78)dBHL were significantly lower than after open radical mastoidectomy treatment of patients in the control group (41 .38 ± 10 .56)dBHL and gas bone conduction (22 .57 ± 5 .96)dBHL(P<0 .05);after different surgical treatment ,the cholesteatoma otitis media total efficiency (92 .00% ) of experimental group was significantly higher than control group (64 .00% ) ( P< 0 .05 ) . Conclusion The complete bi‐style mastoidectomy is the treatment of cholesteatoma otitis media ,which can effectively repair dam‐aged eardrum ,restore patient hearing to the maximum extent ,help to restore patient′s disease and improve the quality of life of pa‐tients .

Objective To evaluate the therapeutic effect of single-session repetitive transcranial magnetic stimulation(rTMS) on motor function in Parkinson's disease(PD).Methods Twenty-four PD patients were enrolled into this two-stage study with cross-over design and divided into two groups randomly.The subjects of first group underwent therapeutic rTMS(0.5 Hz,80% of resting motor threshold,1 000 pulses×2,single-session) on primary motor cortex and underwent controlled rTMS with same stimulation parameters on occipital cortex seven days later.The subjects of second group underwent controlled two sessions of rTMS in reverse sequence.The motor function was assessed by Unified Parkinson's Disease Rating Scale(UPDRS) and Visual Analogy Scales.Results The UPDRS improvement(34.2±7.5%,36.5±8.7%) of subjects after therapeutic rTMS on primary motor cortex was significant higher than that(7.2±3.1%,7.4±3.8%) after controlled rTMS on occipital cortex(P<0.01).The duration of therapeutic effect(39±12 minutes,35±11 minutes) was significant higher than that of controlled rTMS.Conclusion The single-session rTMS has therapeutic effect of short duration on motor performance in PD.

Objective To investigate the epidemiologic features of HIV infections in voluntary blood donors in Zhejiang province.Methods A retrospective study was conducted in 206 cases of HIV-positive blood donors who were found from 2008 to 2010 by blood screening in Zhejiang Province,and the demographic data of those HIV carriers were analyzed using SPSS 16.0 software.Results The HIV-positive rates of voluntary blood donors in 2008,2009 and 2010 were 0.09‰(49/552 585 ),0.11‰( 64/601 639)and 0.15‰(93/600 893),respectively.There were five regions in Zhejiang province where HIV-positive rates exceeded 0.10‰,and the highest one was 0.21‰ in Wenzhou.HIV infection rate of male blood donors was 0.19‰,which was higher than that of female donors (0.02‰,x2 =96.21,P ＜ 0.01 ) ; donors with ages of ＞25-35 had the highest infection rate (0.19‰) among all age groups (x2 =41.94,P ＜0.01 ) ; blood donors with education of junior high school or lower had higher infection rate (0.21‰) than those with education of senior high school and undergraduate or above (0.11‰ and 0.02‰,x2 =78.62,P ＜0.01 ).Infection rate of first-time blood donors in 2008 was 0.12‰,higher than that of repeated donors (0.05‰,x2 =7.26,P＜0.01); while in 2009 and 2010,there was no difference between two groups (x2 =0.16 and 1.35,P ＞ 0.05 ).Blood donors who used mobile donation sites had higher infection rate than those using institutional donation (x2 =18.5,22.0 and 16.8 for 2008,2009 and 2010,P ＜0.01 ).Conclusions The risk of HIV infection is gradually increasing among voluntary blood donors in Zhejiang province.To ensure the blood safety,blood agencies should establish pre-donation health consultation for high-risk blood donors such as young men with low education.

Objective To investigate the relationship between glucose metabolism and dopamine transporter in patients with Parkinson's disease.Methods Eleven patients at stage 2~3 of PD and three patients with essential tremor were examined by 18F-FDG PET and 11C-CFT PET in two separate days within four weeks.The regional glucose binding and dopamine transporter binding were assessed with PET specific software in anterior putamen,posterior putamen,caudate nucleus,thalamus and occipital cortex.The tracer uptake rate between the region of interest and occipital cortex was analyzed as the main variables.Results The marked reduction of 18F-FDG uptake and 11C-CFT uptake was observed in posterior putamen in patients with PD.The reduction of tracers uptake in posterior putamen contralateral to onset side was more significant than the posterior putamen ipsilateral to onset side (P
