Objective To establish a method for detection of RhD(+) red blood cells mixed in D-negative blood by flow cytometry(FCM).Method RhD(+) and RhD(-) RBCs were mixed according to predefined ratios.Cells were indirectly labeled,with IgG anti-D labeled as the first antibody,and FITC-anti-IgG F(ab')2 as the second antibody.The percentage of RhD(+) RBCs was determined by FCM,and the best dosage of IgG anti-D was also defined.The ratio of red cells in the two groups,measured by FCM,was compared with the actual ratio.The consistency of method was also evaluated.Results The effective dosage of IgG anti-D was 1∶4,and 50?l/1?106 cells.When the actual percentages of RhD(+) cell among RhD(-) cells were 2.5%-0.312%,the correlation coefficient between the percentages measured by FCM and the actual percentages was 0.987.The same tubes,containing 10% and 2.5% RhD(+) RBCs,were each tested for 10 times,and their coefficient of variation were 3.4%,and 4.9%,respectively.Conclusion The method of quantifying the RhD(+) RBCs in D-negative blood by FCM is feasible and repeatable,which deserves a further clinical application.

Objective To investigate the clinicopathological features of primary gastric malignant lymphoma.Methods 32 cases of primary gastric non Hodgkin's malignant lymphoma(NHL)were studied by clinicopathology,immunohistochemistry and ultrastructure.Results 3 cases of NHL arose from fundus of stomach,7 cases from body of stomach,8 cases from gastric angle,and 14 cases from gastric antrum.The paraffin sections of all cases were stained.There were 31 cases(96\^9%)exhibiting B cell phenotype,only 1 case(3\^1%)exhibiting T cell phenotype.11 cases of NHL and 6 cases of undifferentiated carcinoma(UC)in stomach were observed comparatively under electron microscope(EM).The ultrastructural characteristics of NHL were much different from those of UC.Conclusion Most primary gastric malignant lymphoma are B cell lymphomas.Immunohistochemistry and ultrastuctural observation are much helpful in the diagnosis and differential diagnosis between NHL and UC.

In recent years,many medical institutions have opened a health management specialty about whose employment prospect students are not optimistic.But there is a huge gap in the position of China’s medicine employment market,and thus the contradiction in employment is very conspicuous.Therefore it is an effective way to resolve the contradiction by enhancing the student's overall quality of professional medical management and improving their professional competitiveness.
