Point-of-care testing (POCT) of blood glucose has been widely used for continuous monitoring of glucose in clinic due to high sensitivity, convenience, accessibility and shorter TAT.It has been developed rapidly in recent years. But glucose POCT is often out of control and management from central laboratory and usually it was performed by non-laboratorians.It becomes the growing concerns that how to avoid the discrepancy between POCT results and central laboratory results, how to ensure POCT quality of each batch of blood glucose results, how to solve issues in the application and ensure that patients' results are accurate and reliable. The hospital should put the POCT management under the whole management system and improve the accuracy of POCT to achieve the complete quality assurance. This article introduced the management program experiences of glucose POCT in Huashan hospital according to the JCI accreditation and CAP-LAP.

Objective To explore the effect of recombinant pEGFP-N3-APC vectors carrying various APC functional domains on the expression of β-catenin in human colorectal cancer cells HT-29.Methods The recombinant plasmids were transfected into HT-29 cells mediated by lipofectamine~(TM) 2000, and detected by green fluorescence and RT-PCR. Western blot was applied to detect β-catenin expression level in HT-29 cells after transfection, and gray scales of electrophoresis strips were analyzed by SPSS 13.0.Results Green fluorescence and RT-PCR made clear that all 5 recombinant plasmids were successfully expressed in HT-29 cells. Western blot showed that β-catenin expression level in HT-29 cells was not affected after being transfected with pEGFP-N3-APC1, pEGFP-N3-APC2 and pEGFP-N3-APC3, and was distinctly affected after being transfected with pEGFP-N3-APC4 and pEGFP-N3-APC5, especially the later one. Conclusion The selected APC5 gene fragment with 15-amino acid repeats and SAMP repeats, which is relatively short, can degrade β-catenin level in HT-29 cells and may be applied in the gene therapy.
