ABSTRACT
Objective To study the clinical value of combination detection of serum pepsinogen (PG ) and fatty acid synthase (FAS) in the diagnosis of gastric cancer .Methods A total of 74 patients with gastric cancer were enrolled as gastric cancer group , 45 patients with benign gastric lesion were enrolled as benign gastric lesion group ,and 78 healthy individuals were enrolled as con‐trol group .Serum levels of PG and FAS were detected by using immunoturbidimetry and enzyme‐linked immunosorbent assay ,and comparatively analyzed between each group .Results Compared with control group ,serum level of PG Ⅰ and PGⅠ /PGⅡ ratio of gastric cancer group were decreased(P0 .05) .The area under the receiver operating characteristic curve of combined detection of PG and FSA in gastric cancer group was 0 .972 ,higher than single detection of PG and FSA .Diagnostic sensitivity and specificity of com‐bined detection of PG and FSA were 95 .50% and 92 .32% ,higher than single detection .Conclusion Combined detection of PG and FAS could increase the diagnostic rate of gastric cancer ,which might have important clinical significant for the early diagnosis of gastric cancer .
ABSTRACT
To realize dynamic and standardized periodical quality control of medical equipment. A set of auto reminder module for medical equipment quality control was established by using the user-defined flow of medical equipment operation maintenance system, and the continuous improvement was realized for medical equipment quality control in some hospital. Dynamic medical equipment quality control was formed from the static one, so that the efficiency of medical equipment quality control was enhanced greatly. References were provided for other hospitals in dynamic and informatzied medical equipment quality control and testing.
ABSTRACT
Objective:Correct application of material management system, promote the standardized management of material, and provide accurate data to the full cost accounting and military hospital economic management information system.Methods: Strictly regulate material process, scientific and reasonable use of material management system, pay attention to the accumulation of experience, good at finding problems, ensure the data accuracy; extracted materials information through the full cost accounting and the military hospital economic management information system, classification and summary of various kinds of data needed. Results: Effective monitoring of the flow of material, realize fine management of material, improve work efficiency, for the full cost accounting and the military hospital economic management information platform to provide accurate data.Conclusion: The correct application of material management system, for the material use and management departments to provide convenient and at the same time, also deliver a strong support for financial work.
ABSTRACT
AIM:To further study the anti-tumor effect of angiostatin, an anti-human angiostatin monoclonal antibody was prepared and identified.METHODS:The hybrodoma techniques were used. The BALB/C mice were immunized with angiostatin. The supernatant of cell culture were collected and screened by ELISA and double immunodiffusion.RESULTS: There cell lines which steadily secreted the anti-angiostatin monoclonal antibody were identified by ELISA and double immunodiffusion. The antibody was IgG1 and specifically recognized angiostatin without crossing reactions to rhIL-2, rhTNF-?, rhIFN-? and serum proteins.CONCLUSION: The antibodies secreted by three hybridoma cell lines identified by several methods were specific antibodies of angiostatin.
