Objective To perform the comparative analysis on the use situation of 3 kinds of dry chemical analyzers according to the industrial standards YY/T0655-2008.Methods With the Roche Cobas P800 automatic biochemical analyzers as the reference instrument,the accuracy,intra-assay precision,linearity,etc.in 3 kinds of dry chemical analyzers were evaluated.Results 3 kinds of dry chemical analyzers met the requirements of the industrial standards YY/T0655-2008,but the precision of imported instrument was significantly better than that of the domestic instrument.Conclusion In order to ensure the comparability and consistency of the detection results among instruments,the instruments should be regularly calibrated and performed the comparative experi-ments,the premise of calibration and comparison should be using 1/4 of the precision level in the CLIA′88 indicators as the indica-tor,not satisfying with the precision requirements in YY/T0655-2008,only in this way can the waste of blood and donors going a-way be avoided.

[Objective] To observe the effect of Xiangdan injection with the actions of activating blood and removing stasis for the treatment of acute tubular necrosis (ATN) after kidney transplantation. [Methods] Twenty-six patients with ATN after kidney transplantation were randomized into groups A and B. The two groups were treated with triple immuno-suppressive agents of cyclosporin A, prednisone and mycophenolic acid, with medicines for protecting liver function and gastric mucosa, and with preventive measures from infection. Additionally, group A (n = 16) was treated with Xiangdan injection, while group B ( n = 10) was not. After treatment, time for hemodialysis, renal function and renal flow resistance index of the transplanted kidney were compared between the two groups after the occurrence of ATN. [Results] Compared with group B, time for hemodialysis was shortened, the decrease of serum creatine (SCr) in the transplanted kidney quickened, and renal flow resistance index (RI) of the transplanted kidney decreased (P 0.05). [Conclusion] Xiangdan injection with the actions of activating blood and removing stasis can promote the early recovery of ATN after kidney transplantation.
