The validation method was performed to the EMIT determination of CsA blood concentration, the CsA whole blood trough concentrations (Co) of patients in different time periods after renal transplantation were monitored, and combined with the clinical complications, the statistical results were analyzed and compared. EMIT was precise, accurate and stable, also with a high quality control. The mean postoperative blood concentration of CsA was as follows: 〈1 month, (281.4± 57.9)ng/mL; 2 - 3 months, (264.5 ± 41.2) ng/mL; 4 - 5 months, (236.4 ± 38.9) ng/mL; 6 - 12 months, (206.5± 32.6)ng/mL; 〉12 months, (185.6± 28.1)ng/mL. The toxic reaction rate of CsA blood concentration within the recommended therapeutic concentration was 14.1%, significantly lower than that of the none-recommended dose group (37.2%) (P〈0.05); the transplantation rejection rate was 4.4%, significantly lower than that of the none- recommended dose group (22.5%) (P〈0.05). Using EMIT to monitor the blood concentration of CsA as the routine laboratory method is feasible, and is able to reduce the CsA toxicity and rejection significantly, leading to achieving the desired therapeutic effect.展开更多

The examination of DNA polymorphism by restriction endonuclease BstE Ⅱ and the examination of AFP by bioluminescence immunoassay technique were carried out. The results have a significant difference( P <0.005). But the positive rate of AFP is higher than that of DNA polymorphism. The experimental result shows that the change of the DNA polymorphism of IGF-Ⅱis not the only carcinogenic factor. The suggested unite examination is the best method for the diagnosis of the primary hepatocellular carcinoma.展开更多
