OBJECTIVE:To observe the therapeutic effect of Weixiao mixture on functional dyspepsia.METHODS:In a single-blind design,patients were randomly divided into Weixiao mixture group and domperidone group to compare the ther?apeutic effect between two preparations.RESULTS:The total effective rates were83.87%for Weixiao mixture group and75.00%for domperidone group(P

Objective To evaluate the performance of ELISA by detecting low quantitative HBsAg in serums.Methods 305 serum samples that the quantitation range was from 0.05 IU/ml to 9.99 IU/ml were collected,and then detected by ELISA. Results The rate of patients with low quantitation of HBsAg was 18.12% in patients with positive HBsAg.The total de-tected rate of ELISA was 87.87%,and the rate of 0.05~0.11,0.12~0.20,0.21 ~0.50,0.51 ~ 1.00,1.01~5.00 IU/ml and 5.01~9.99IU/ml were 36.00%,61.11%,78.38%,84.62%,99.11% and 100.00%,respectively.The differences were statistically significant between the detected rates of each group(χ2 =99.84,P =0.000).There was high correlation coeffi-cient between the results detected by ELISA and by CMIA(r = 0.874,P = 0.000).Conclusion The clinical laboratory should be careful to apply the method of ELISA to detect HBsAg for its missing detection in samples with low quantitation of HBsAg.
