Construction and application of cloud-based hospital information system / 医疗卫生装备

Objective To explore the construction and application of cloud-based healthcare information system (CHIS).Methods The process of CHIS employment and implementation for primary-level medical and healthcare institutions was elaborated by the example of a city after the analysis and comparison of mode difference between traditional and cloud construction.Results CHIS integrated regional medical resources and realized integrated application of medical and public healthcare resources,mobile integration of regional operation and continuous innovation in construction mode,and facilitated uniformed management,high-efficiency running and maintenance as well as business development.Conclusion CHIS contributes to enhancing medical inforrnatization in primary institutions,promoting continuous medical innovation and innovating medical informatization mode.

Isolation and Characterization of Human Chorionic Membranes Mesenchymal Stem Cells and Their Neural Differentiation

Mesenchymal stem cells (MSCs) can be obtained from a variety of human tissues. Placenta has become an attractive stem cell source for potential applications in regenerative medicine and tissue engineering. The aim of this study was to localize and characterize MSCs within human chorionic membranes (hCMSCs). For this purpose, immunofluorescence labeling with CD105 and CD90 were used to determine the distribution of MSCs in chorionic membranes tissue. A medium supplemented with a synthetic serum and various concentrations of neurotrophic factors and cytokines was used to induce hCMSCs to neural cells. The results showed that the CD90 positive cells were scattered in the chorionic membranes tissue, and the CD105 positive cells were mostly located around the small blood vessels. hCMSCs expressed typical mesenchymal markers (CD73, CD90, CD105, CD44 and CD166) but not hematopoietic markers (CD45, CD34) and HLA-DR. hCMSCs differentiated into adipocytes, osteocytes, chondrocytes, and neuronal cells, as revealed by morphological changes, cell staining, immunofluorescence analyses, and RT-PCR showing the tissue-specific gene presence for differentiated cell lineages after the treatment with induce medium. Human chorionic membranes may be the source of MSCs for treatment of nervous system injury.

The comparison and evaluation of the self-developed control products and the internal quality control products detection of NT-proBNP by electrochemiluminescence / 国际检验医学杂志

Objective To investigate the preparation of internal quality control products of NT‐proBNP by electrochemilumines‐cence detection .Methods The serum with high and normal levels of NT‐proBNP were collected and divided into low‐value group and high ‐value group .The expected target value ,inter‐batch duplicability ,imprecision and the stability within batch were detected . After effective verification ,we evaluated the bias between self developed internal quality control products and Roche factory quality control materials by comparative test .Results The repeatability ,stability and imprecision of self developed NT‐proBNP were all appropriate to internal quality control products and meeting meet the clinical testing standards .The control range was significantly less than that permitted by Roche ,so it can meet the internal quality control requirements .Conclusion The self developed NT‐proBNP internal quality control products can replace the imports quality control products .

Research on Integration of PACS and HIS / 医疗卫生装备

Objective To explore the ways of PACS and HIS integration.Methods Firstly,the significance and specific objective of PACS/HIS Integration is presented,and then five methods are introduced in detail including direct access interface or database,distributed integration ways based on mid-list,middleware,HL7 and CORBA.Results The five kinds of ways on integration have respective characteristics,information exchange and data sharing between PACS and HIS are realized.Conclusion Each hospital should select the proper way based on specifics situation.With the development of HIS and PACS standardization,distributed integration ways based on HL7 and CORBA will be the future development trend.
