In this study ,we detected the positive rate of anti‐HBs and anti‐HBc antibody among the subject population in Fujian Medical University Union Hospital ,and to evaluate different detection methods of anti‐HBc antibody .The positive rate of anti‐HBs and anti‐HBc antibody were detected by chemiluminescent microparticle immunoassay (CMIA) and one‐step com‐petitive enzyme‐linked immunosorbent assay (ELISA) from the year 2012 to 2013 .The subject population was divided into three groups :group 1 with the age of less than 2 years old ,group 2 with the age of 2‐20 years old ,and group 3 with the age of more than 20 years old .The positive rates of anti‐HBV antibody in the different groups were analyzed .Furthermore ,anti‐HBc antibody of 92 samples selected from the immunized population was detected by CMIA and three kinds of ELISA reagents . Meanwhile ,the detection of anti‐HBc antibody by the same ELISA reagent but different operating modes were performed in these samples .The highest positive rate of anti‐HBs antibody was detected in group 1 ,and there was no significance difference of positive rate between two detection methods of anti‐HBs antibody among three groups .The positive rate of anti‐HBc anti‐body using CMIA was significantly lower than those with ELISA among group 1 and 2 .Among the 92 samples ,the positive rate of anti‐HBc antibody was 2 .2% using CMIA .With three kinds of method of ELISA reagent ,the positive rate of anti‐HBc antibody were 79 .3% ,82 .6% and 94 .6% ,respectively ,and there was no statistical significance among the results of three ELISA reagents .Anti‐HBc was not detected from 19 samples using ELISA methods with different operating modes .It's con‐cluded that the anti‐HBs antibody declined with the increase of age ,and it is necessary to discriminate the specific population to strengthen immune system .The obviously higher positive rate of anti‐HBc antibody was found by ELISA in immunized popula‐tion than that by CM IA . Concerning on the false positive of ELISA , specimen sampling with one specific test item or the CMIA method was recommended to detect the anti‐HBc antibody .

Objective To explore the relationship between quality life and TCM constitutions of elderly patients with hypertension in a community in Shanghai; To provide the basis for the suitable and feasible community elderly hypertension management method. Methods Through multistage stratified sampling method, 808 elderly patients with hypertension in the community were investigated for their life quality and TCM constitutions on the basis of inform consent and voluntary participation. The life quality and TCM constitution characteristics as well as the relationship were analyzed by applying the statistic analysis software. Results Among the investigated elderly patients with hypertension in the community, 97.28% cases’ overall life quality was above the middle level and 91.46% cases’ self-evaluated health and quality of life scores were above the middle level. 54.70% cases were gentleness type, and the biased constitution was dominated by qi deficiency, yang asthenia, yin asthenia and phlegmatic hygrosis. The relationship between life quality and TCM constitutions may be existent. If TCM constitutions tended to be gentleness type, the physical score and the psychological score would be higher, which leaded to better quality of life. Conclusion TCM constitution characteristics are associated with quality life of elderly hypertension patients in the community. Intervention targeted on the results of TCM constitution identification would be better to prevent and control hypertension and improve health level and quality of life.
