Objective To study the dilution model of the early pregnancy test strip for the quantitative detection of serumβ-hu-man chorionic gonadotropin(β-hCG)level by the Abbot AxSYM detection system and its application.Methods The detection re-sults of serumβ-hCG level in 5 612 outpatients and inpatients of the internal medicine department and the gynecology and obstetrics department during 5 years were retrospectively analyzed.In addtion,234 serum samples from the patients were collected for prelimi-narily determining the serumβ-hCG level by the early regnancy test strip and then the quantitative detection of serumβ-hCG level was detected by the Abbot AxSYM detection system.Results The retrospective analysis showed that 241 cases(4.6%)were low-age pregnant women.The qualitative screening was necessary.The screening model was successfully established.But one thing to note was that the part of serum sample needed to be taken out and put into another tube for determination.Conclusion Establishing the rational and effective dilution interpretation model of early pregnancy test strip for screening serumβ-hCG can bring the econom-ic and time benifits for the routine detection work of the Abbot AxSYM detection system.

Cellulase system contains a series of complex components.There are still some problems remained unclear in cellulase and its mechanism of hydrolyzing lignocellulosic materials and its hydrolysis kinetics,so profound study is needed.The rapid development of many kinds of new interdiscipline such as biochemistry,molecular biology and gene engineering,has further clarified the structure and function of cellulase,and the relationshi Pof its gene expression and regulation,and furthermore resulted in derivative study methods about cellulase in more aspects.Cellulase system components according to synergistic catalytic mode and the sequence of the homology amino acids similarity,summarizes traditional detection methods of enzyme components,and emphasizes on research progress of various biosensors applied in detection of cellulase activity and gene expression was introduced.

Objective To explore the relationship between intercranial hemodynamics and nitric oxide(NO),endothelin(ET),nailfold microcirculation in patients with migraine.Methods 50 patients with migraine and 40 normal controls underwent the measurement of intracranial hemodynamics,naifold microcirculation and the level of plasma ET,NO.The results of the two groups were compared and analyzed.Results The blood flow velocity of intracranial arteries was significantly higher in the patients than that in the normal controls( P
