ABSTRACT
Objective To analyze and evaluate the precision ,accuracy and linearity of the chemiluminescence method for detec‐ting plasma BNP .Methods According to the experimental schemes of CLSI EP15‐A2 ,EP6‐A files and other relevant documents , the precision ,accuracy and linearity of the Siemens Centaur XP chemiluminescence instrument for detecting BNP ,and the detection results were compared with the performance declared by manufacturer or the quality target formulated by laboratory .Results The imprecision of BNP detected by the chemiluminescence method was less than 1/3 TEa regulated by the Clinical Laboratory Center of Ministry of Health (allowable total error);the variation coefficient index (CVR) of internal quality control data was less than ± 2;the relative bias of the results of external quality control blind samples with the target values were less than Tea regulated by the Ministry of Health ;the linear evaluation results showed that BNP was once linearity in the range of 5 .3‐4696 .7 pg/mL .Conclusion The precision ,accuracy and linearity of the Siemens Centaur XP chemiluminescence instrument for detecting BNP can accord withthe quality objectives requirements and meet the clinical needs .
ABSTRACT
Objective To study the status of cervical lesion and cognition of women in childbearing age in Xining and its related factors .Methods From March 2012 to August 2013 ,1 500 female patients were selected .All the women accepted pap smear and HPV DNA test .Meanwhile ,questionnaires were distributed for cervical cancer in the region and identify the cognition related fac-tors .Results The results showed that among the 1 500 cases of the sample population ,number of cervical intraepithelial neoplasia grade Ⅰ(CIN Ⅰ)was 48(3 .2% )and cervical intraepithelial neoplasia grade Ⅱ and above was 22(1 .5% ) .674 cases got a good cog-nition ,while 826 cases got a poor one .Multivariate analysis showed that age ,marital status ,education level ,place of residence ,occu-pation and family income were closely related to women′s cognition of cervical cancer .Conclusion The status of cervical lesions of women in childbearing age in Xining is generally common ,but the overall cognition is poor ,which is mainly related to age ,marital status ,occupation ,place of residence and income .
ABSTRACT
OBJECTIVE@#To study the diagnostic value of high-resolution computed tomography (HRCT) and multiplanar reconstruction (MPR) in assessment of semicircular canals disease.@*METHOD@#Eighty-three patients were scanned with HRCT and the original data were processed with MPR. The semicircular canals full length was respectively observed in one image of MPR in the normal ears. The abnormal location of the canal were observed.@*RESULT@#In one image the full length of the horizontal, superior and posterior semicircular canal can be respectively displayed in one image of MPR in normal ears. By this way ,1 superior semicircular canal dehiscence (SSCD)was found in precaution group, 1 superior and 2 horizontal semicircular canal blocked, 1 vestibular aqueduct (VA) joined into superior semicircular canal and 2 VAs joined into posterior semicircular canal and abnormity of the three semicircular canals were found in SNHL.@*CONCLUSION@#MPR canould display the three canals full length in one picture and have a high specificity in the diagnosis of the semicircular canal abnormity.

Ice microalgae, which inhabit in the extreme conditions of polar marine environment, not only play an important role in Antarctica ecosystem but also show broad prospects in basic research and application. Ice microalgae have the specific physiological and metabolic properties that are responsible for their adaptation and acclimation to the special polar conditions. Based on the references in the recent twenty years and the partial research results of author's, the ice microalgae composition and distribution, and the application in bait, unsaturated fatty acid, anti-freezing proteins, UV-absorbing pigments and other active substances are reviewed. It is expected to provide references for the research and active substance exploitations of ice microalgae.
