ABSTRACT
Objective To evaluation the performance of double antigen sandwich time-resolved fluoroimmunoassay(TRFIA)for specific total antibody to Treponema pallidum (TP).Methods Specific total antibody to TP was detected by a double antigen TRFIA based on recombinant multi epitope chimeric antigen.The methodological precision,low limit of detection,accuracy,linearity,reference standard coincidence rate and other analytical performance indicators were evaluated,and clinical comparison research trials were completed.The x2 test was used for the difference between two methods results,the P ＜0.05 which represents the difference was statistically significant.Results The intra-assay and inter-assay coefficients of var iation (CV) were both less than 10％ respectively.The low limit of detection was 0.05 mIU/ml.The relative deviation of de tecting the national standard was not exceed 10％.The linear range was 1.50～ 155.00 mIU/ml and the linear correlation co efficient could be reached 0.999 9.The performance of detection national reference could meet the national accreditation requirements.The consistent rate was 100 ％ when the TRFIA methodology detected the standardized serum plate.The parallel test of TRFIA and treponema pallidum gelatin agglutination test (TPPA) were completed,the total coincidence rate was 99.56％,and the Kappa index was 0.990 6.Conclusion Their result showed that the TRFIA methodology is high sensitivity,accuracy,wide linear range,and highly clinical coincidence rate,which is valuable for clinical application.
ABSTRACT
<p><b>OBJECTIVE</b>To search for the best therapy for simple obesity.</p><p><b>METHODS</b>Eighty cases were randomly divided into 3 groups. The body acupuncture group were treated based on the syndrome of heat of stomach and intestine, syndrome of spleen deficiency and stagnation of dampness, and syndrome of spleen and kidney yang-deficiency; the auricular and body acupuncture group were treated by the syndrome treatment of body acupuncture combined with auricular point sticking; the observation group were treated by the combined auricular and body acupuncture treatment plus moving cupping on back-shu points. Body weight, BMI, body fatd, blood lipids and clinically main symptoms before and after treatment were investigated.</p><p><b>RESULTS</b>The total effective rate was 69.6% in the body acupuncture group, 76.0%. in the auricular and body acupuncture group, and 90.6% treated in the observation group, with significant differences in the therapeutic effect, clinically main symptoms, external indexes of obesity and kidney ang-blood lipid metabolism between the observation group and the body acupuncture group. The various indexes in the auricular and body acupuncture group were superior to those iwere tthe body acupuncture group, with no significant differences in most indexes.</p><p><b>CONCLUSION</b>Auricular and body acupuncture combined with moving cupping at back-shu points has obvious therapeutic effect on simple obesity and this is a better therapy for simple obesity.</p>
