Objective Extent of resection is an important prognostic factor in patients undergoing surgery for glioblastoma( GBM).Recent evidence suggests that intravenously administered fluorescein sodium associates with tumor tissue,facilitating safe maximal resection of GBM. In this study,the authors evaluate the safety and utility of intraoperative fluorescein guidance for the prediction of histopathological alteration both in the contrast-enhancing( CE) regions,where this relationship has been established,and into the nonCE( NCE),diffusely infiltrated margins. Methods Thirty-two patients received fluorescein sodium( 3 mg/kg) intravenously prior to resection. Fluorescence was intraoperatively visualized using a Zeiss Pentero surgical microscope equipped with a YELLOW 560 *** localized biopsy specimens were acquired from CE and NCE regions based on preoperative MRI in conjunction with neuronavigation. The fluorescence intensity of these specimens was subjectively classified in real time with subsequent quantitative image analysis,histopathological evaluation of localized biopsy specimens,and radiological volumetric assessment of the extent of *** Bright fluorescence was observed in all GBMs and localized to the CE regions and portions of the NCE margins of the tumors,thus serving as a visual guide during resection. Gross-total resection( GTR) was achieved in 84% of the patients with an average resected volume of 95%,and this rate was higher among patients for whom GTR was the surgical goal( GTR achieved in 93. 1% of patients,average resected volume of 99. 7%). Intraoperative fluorescein staining correlated with histopathological alteration in both CE and NCE regions,with positive predictive values by subjective fluorescence evaluation greater than 96% in NCE regions. Conclusions Intraoperative administration of fluorescein provides an easily visualized marker for glioma pathology in both CE and NCE regions of GBM. These findingssupport the u

Chemical Characteristics of Carbonaceous Aerosols During Dust Storms over Xi'an in China

Advances in Atmospheric Sciences 2008年第5期25卷 847-855页

Characterization of carbonaceous aerosols including CC （carbonate carbon）, OC （organic carbon）, and EC （elemental carbon） were investigated at Xi＇an, China, near Asian dust source regions in spring 2002. OC varied between 8.2 and 63.7μgm^- 3, while EC ranged between 2.4 and 17.2 μ m^-3 during the observation period. OC variations followed a similar pattern to EC and the correlation coefficient between OC and EC is 0.89 （n=31）. The average percentage of total carbon （TC, sum of CC, OC, and EC） in PM2.5 during dust storm （ds） events was 13.6%, which is lower than that during non-dust storm （Nds） periods （22.7%）. CC, OC, and EC accounted for 12.9%, 70.7%, and 16.4% of TC during ds events, respectively. The average ratio of OC/EC was 5.0 in ds events and 3.3 in Nds periods. The OC-EC correlation （R^2=0.76, n=6） was good in ds events, while it was stronger （R^2=0.90, n=25） in Nds periods. The percentage of watersoluble OC （WSOC） in TC accounted for 15.7%, and varied between 13.3% and 22.3% during ds events. The distribution of eight carbon fractions indicated that local emissions such as motor vehicle exhaust were the dominant contributors to carbonaceous particles. During ds events, soil dust dominated the chemical composition, contributing 69% to the PM2.5 mass, followed by organic matter （12.8%）, sulfate （4%）, EC （2.2%）, and chloride （1.6%）. Consequently, CC was mainly entrained by Asian dust. However, even in the atmosphere near Asian dust source regions, OC and EC in atmospheric dust were controlled by local emission rather titan the transport of Asian dust.
