Objective To verify the performance of HBV detection reagents for Roche MODULRA E170 electrochemical lumi-nescence analyzer .Methods Referring to CLSI EP15-A document ,the minimum detection limit ,linear range ,precision and accuracy of the HBV detection reagents were verified .Results The intra-assay coefficient of variation ,total coefficient of variation ,linear range of HBsAb ,and minimum detection limits of HBsAg and HBeAg of the HBV detection reagents for MODULRA E170 electro-chemical luminescence analyzer all reached the performance claimed by manufacturer .Conclusion The performance of HBV detec-tion reagents for MODULRA E170 electrochemical luminescence analyzer is excellent ,and it can meet the needs of clinical diagnosis and treatment .

Objective To observe the effect of Yiqi Huaxian Decoction (YHD) on transforming growth factor ?1(TGF-?1 )mRNA expression in rats alveolar macrophages (AM) and pulmonary interstitial macrophages (IM).Methods Ninety-six Wistar rats were randomized into sham-operation group,model group,YHD (4 g?kg-1?d-1) group,and hydrocortisone (20 mg?kg-1?d-1) group.Bleomycin A5 was injected into the rats' trachea to induce pulmonary fibrosis.AM and IM were isolated for the culturing after modeling for 7 and 28 days.Molecular in-situ hybridization (ISH) was used for the detection of TGF-?1 expression in AM and IM.Results Percentage of cells in AM and IM with TGF-?1 positive expression and the score of optic density were increased in the model group (P
