ABSTRACT
Objective To understand the quality of malaria blood examinations in township?level hospitals,so as to provide the evidence for continuing the malaria blood examinations in the stage of post?malaria elimination. Methods A total of 64 township hospitals were investigated and 640 negative malaria blood slides were scored individually according to 10 indicators inMalaria Elimination Technical Schemein 2013 and 2014. The single and multiple indicators were calculated,and the work of blood examinations and situation of technicians were investigated. The data of malaria blood examinations and patient discovery in township hospitals of Nantong City were collected and analyzedduring the period of 2011-2014. Results Forthe single indi?cator,29.5%of the thick blood films did not reach the standard,and 35.8%of thin blood films did not reach the standard. For the multiple indicators,blood slides with more than 4 indicators below the standard(poor quality)accounted for 32.5%. From ma?laria blood examinations and malaria situation,the number of slides was 194 635 during the period of 2011-2014,and there were no local vivax malaria casesin 4consecutive years from 2011 to 2014,andlocal malaria has been effectively controlled in Nantong City. For health facilities where malaria patients initially presented,the township and village level accounted for 16.3%,and county and higher level accounted for 83.7%. Conclusions The quality of malaria blood examinations in township level hospitals of Nantong City is not high and the microscopic examination has a relatively low efficiency in the discovery of ma?laria cases. A new model for malaria blood examinations needs to be further explored.
ABSTRACT
Objective To assess the value of contrast-enhanced ultrasonography (CEUS ) in diagnosing BI-RADS 4 breast lesion.Methods The CEUS findings of 79 breast lesions of BI-RADS 4 were analyzed,and the CEUS diagnosis was made according to our preliminary study results.Histology results were served as golden reference.Results Of all the 79 breast lesions that were confirmed by histopathology results,36 were malignant and 43 were benign.The differences of morphologic features of area variety, margin,heterogeneous or homogeneous distribution between benign and malignant lesions were significant (P < 0.05 ).The area under ROC curve of correction BI-RADS classification in the diagnosis of breast cancer was 0.938,and it was significantly higher than that of the BI-RADS classification (0.889,Z =2.209, P =0.0272).Conclusions CEUS can improve the diagnostic accuracy of breast lesions preoperatively.
