ABSTRACT
A method for improving the biocompatibility of the intraocular lens (IOL) and reducing the cell attachment was adopted in this study. The alpha-Allyl glucoside was used for the surface modification of the poly methyl methacrylate (PMMA) IOL by way of plasma-induced in situ polymerization. The surfaces of the control and treatment IOLs were characterized by contact angle estimation and ESCA techniques. The resolution, diopter and anti-fatigue of loops were determined by physical and optical methods. Cell attachment on the surfaces was examined by light microscopy. The results indicated that all of the treatment groups had excellent physical and optical properties. The modification with the use of alpha-Allyl glucoside could improve the hydrophilicity of the anterior surface of the PMMA IOLs and reduce the cell attachment.

Purpose:To Explore the requirements and accuracy for applying Microwave-ELISA Two-Steps-Test to the factory physical examination.Methods:Do the Microwave-ELISA Two-Steps-Test for 1,128 factory physical examination specimens that need the HBsAg and HBeAg inspection;comparing the result to the conventional ELISA test;and retest the specimens with the HBsAg-positive results.Results:There are 119 HBsAg-positive and 32 HBeAg-positive results for the ELISA test;there are 122 HBsAg-positive and 34 HBeAg-positive results for the microwave test;all the HBsAg-positive results are proved to be positive by using the colloid gold HbsAg rapid testing paper.Conclusion:Microwave-ELISA Two-Steps-Test is timesaving,simple and high sensitive for testing Hepatitis-B signs,which can reduce the hook phenomenon and can be used to do the large number of HBsAg and HBeAg checks in factory physical examinations.It can hasten the result report and greatly improve the efficiency.
ABSTRACT
Objective To compare the operation modes of AP-960 full automated ELISA system.Methods Two models were tested: beginning with adding specimens(model 1) and beginning with adding enzymes(model 2).The following factors were compared: the consumption of suckers,usage of time,result of test and the usual alarm during the test.Results The consumptions of suckers were 564 and 84 respectively.The needing time of the former mode was 125 minutes and that of the latter mode was 90 minutes.Conclusion The mode beginning with adding enzymes(model 2) is better for the current status of our clinical laboratory.
ABSTRACT
Objective To develop a set of network information system for laboratory equipment management. Methods According to the requirement of laboratory equipment management provided by laboratory section, a professional laboratory software company developed the software by using SQL Server 2000 as database and Delphi 7.0 as program language. Results Data of laboratory equipment in hospital were shared and communicated. Laboratory equipment management was standardized and work efficiency and quality were improved. Conclusion The software is convenient and practical with high popularization and application value.
