Objective:To investigate the use of the reference intervals for blood cell counting and the reference of industry standard in China.Methods:Information from all laboratories was collected using online questionnaire in 18 reference intervals survey in blood cell counting in 2019. The information includes the source of the reference intervals, the verification of the reference intervals, and the upper and lower limits of the reference intervals, the method used, the instrument, the reagent and the calibrator. Microsoft Excel 2007 software was used to analyze the results of all laboratories. The median and 95% confidence interval were calculated. The distribution of the reference intervals for blood cell counting and their conformance to industry standards were analyzed.Results:2, 869 labs reported the data. The main sources were industry standards and National Guide to Clinical Laboratory Procedures. The proportion was 33.30%-35.02% and 28.55%-30.90% respectively. 49.44%-55.13% of laboratories validated the reference interval when citing industry standards. The reference interval grouping of most laboratories (89.37%-91.69%) cited in RBC, Hgb and Hct were consistent with the industry standards. We compared the upper and lower limits of the reference intervals with that given by the industry standards, when the lower limit of the reference intervals of mean corpuscular hemoglobin concentration, absolute neutrophils count, absolute basophils count, absolute monocyte count, and lymphocyte percentage were compared. The upper limit of reference intervals of neutrophils percentage as well as upper and lower limits of reference intervals of mean corpuscular volume, mean corpuscular hemoglobin, absolute eosinophil count, basophils percentage, and monocyte percentage were also compared. The median and mode were equal and consistent with industry standards. For other labs, the upper and lower limits of the reference intervals were not consistent with the reference intervals given by the industry standards.Conclusion:The use of reference intervals for blood cell counting was not the same, and the implementation of industry standards was not optimistic. A considerable number of laboratories had not verified the reference intervals, so it was necessary to promote the industry standards for reference intervals.

BACKGROUND:The principle of lyophilization is to sublimate the solvent of frozen materials in vacuum and retain the solute, thus making a pore structure. OBJECTIVE: To produce a chitosan tubular scaffold by lyophilization, and to test its physicochemical properties. METHODS: The chitosan tubular material was prepared by lyophilization method, folowed by gross observation and electron microscopic observation. The chitosan tubular material samples were placed into PBS solution and pure water for 50 days, respectively, and then immersed in trypsin liquid for 1 day folowed by embedded into the muscle and dorsal skin of neonatal Sprague-Dawley rats for 30 days. The degradation rate and porosity of the material were observed and calculated. The breaking strength and compressive strength of the material were determined both under drying and soaking conditions using tensile instrument and pressure meter, respectively. RESULTS AND CONCLUSION:The external form of the chitosan tubular material was normaly tubular. Under the electron microscope, it was composited by different size pores, and the pore size was 50-200μm. The degradation rates of the material were (5.33±0.12)% in PBS, (11.26±0.15) in water, 0.012% in the trypsin liquid and (35.2±3.7)in vivo. The porosity rate was (97.5±1.5)%. The breaking strength and compressive strength of the material was higher under the drying state than under the soaking state (P < 0.05). These findings indicate that the lyophilization method can produce the chitosan tubular material with good porosity rate and degradation rate as wel as good tensile ability and compressive capability.
