RESUMO
Objective To compare the consistency of the results of clinical specimens between Tecan Freedom Evolyzer-2200 automated enzyme immunoassay analyzer and manual ELISA method,so as to explore more scientific and reliable test method.Methods Ninety samples were randomly selected from clinical and physical examination,the IMARK2 microplate reader and the instrument operating manual sample measurement was used to test hepatitis A,hepatitis B 5,hepatitis C,hepatitis E 2,TP and HIV,and the results were given correlation and linear regression analysis.Results For the test items of HBsAg,HBsAb,HBeAg,TP,HIV,the correlation coefficient was r2＞ 0.9,the data showed a good correlation,and for HAV-IgM,HBeAb,HBcAb,HCV,HEV-IgM,HEV-IgG,the correlation coefficient was 0.9＞ r 2 ＞ 0.6.Compared with manual method,the total coincidence rate of automated enzyme immunoassay analyzer was 96.9％ in 11 indexes of 90 samples.Conclusions Automatic and manual ELISA method has a good correlation.Automatic ELISA also greatly reduce the labor burden of laboratory personnel,improve efficiency,should be strengthened in clinical practice.
RESUMO
A 61-year-old female presented with 4 years history of left-sided hemifacial spasm. Head MRI and angiography indicated left vertebral artery dissecting aneurysm which compressed ipsilateral cranial nerves Ⅶ and Ⅷ. Microvascular decompression was performed. The dissecting aneurysm was pushed apart and the distal part of the parent artery was adhered to the dura on the petrosum. The compressed nerves were totally decompressed. The symptom of facial spasm was completely resolved immediately after surgery and did not recur during 6 months of follow up.
