Objective To investigate the status of clinical blood transfusion from 2008 to 2014 in order to standardize clinical transfusion management and improve the clinical rational usage of various blood components .Methods By various blood compo‐nents transfusion ,the average quantity of clinical blood transfusion ,4 common blood types and the usage of red blood cells and platelet in different departments were analyzed and compared .Results The rate of blood component transfusion remained at 100%over the 2008 - 2014 year .The utilization of platelet was the highest ,followed by red blood cells and plasma ,and the amount of cryoprecipitate was the least from 2010 .The total consumption of blood was increasing each year ,but there was a downward trend at the average usage of clinical blood ,and also there were significant differences among 4 common blood types ,and the blood compo‐nent transfusion rate was different in different departments in hospital .Conclusion From 2008 to 2014 ,the blood transfusion is ap‐propriate and reasonable ,but still can be improved by effective means .

Objective: Progressive supranuclear palsy (PSP) involves a variety of visual symptoms that are thought to be partially caused by structural abnormalities of the retina. However, the relationship between retinal structural changes, disease severity, and intracranial alterations remains unknown. We investigated distinct retinal thinning patterns and their relationship with clinical severity and intracranial alterations in a PSP cohort. Methods: We enrolled 19 patients with PSP (38 eyes) and 20 age-matched healthy controls (40 eyes). All of the participants underwent peripapillary and macular optical coherence tomography. Brain 11C-2β-carbomethoxy-3β-(4-fluorophenyl) tropane (11C-CFT) and 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography imaging were also performed in patients with PSP. We investigated the association between retinal thickness changes and clinical features, striatal dopamine transporter availability, and cerebral glucose metabolism. Results: The peripapillary retinal nerve fiber layer (pRNFL) and macula were significantly thinner in patients with PSP than in controls. The thickness of the superior sector of the pRNFL demonstrated a significant negative relationship with the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale part III and Hoehn and Yahr staging scale scores. A significant negative correlation was found between outer inferior macular thickness and disease duration. Outer temporal macular thickness was positively correlated with Montreal Cognitive Assessment scores. In PSP, lower outer temporal macular thickness was also positively correlated with decreased dopamine transporter binding in the caudate. Conclusion The pRNFL and macular thinning may be candidate markers for monitoring disease severity. Additionally, macular thinning may be an in vivo indicator of nigrostriatal dopaminergic cell degeneration in PSP patients.
