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:To discuss the performance of visual score and heart-to-contralateral lung (H/CL) ratio of 99Tc m-pyrophosphate (PYP) SPECT/CT scintigraphy for diagnosing transthyretin-related cardiac amyloidosis (ATTR-CA) by using Meta-analysis. Methods:Relevant studies on 99Tc m-PYP SPECT/CT diagnosis of ATTR-CA published before August 20, 2023 from databases including Pubmed, EMbase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang and China Science and Technology Journal Database (VIP) were retrieved. Articles were screened and indices which reflect the diagnostic efficiency such as sensitivity and specificity were extracted. Forest plots were drawn, and subgroup analysis was performed to analyze the heterogeneity. Results:A total of 160 articles were retrieved, and 11 articles involving 1 802 patients were enrolled, of whom 605 were diagnosed with ATTR-CA. All 11 articles were enrolled when analyzing the diagnostic efficiency of visual score for diagnosing ATTR-CA. After integration, the sensitivity and specificity were 0.95(95% CI: 0.91-0.97) and 0.95(95% CI: 0.90-0.98), respectively. Ten articles (1 611 patients) were enrolled when analyzing the diagnostic efficiency of H/CL ratio for diagnosing ATTR-CA. After integration, the sensitivity and specificity were 0.93(95% CI: 0.82-0.98) and 0.99(95% CI: 0.90-1.00), respectively. Subgroup analysis indicated that lack of uniformity in diagnostic criteria was the primary source of heterogeneity. Conclusion:99Tc m-PYP SPECT/CT scintigraphy exhibits high diagnostic efficiency for ATTR-CA.

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.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.
