ABSTRACT
Objective To study the expression of CD269 and CD317 antigens in bone marrow cells of patients with multiple myeloma (MM),analyze its correlation with the laboratory indexes reflecting the progression of MM and evaluate its value in clinical diagnosis and treatment.Methods 63 newly diagnosed MM patients were selected as the study group by a casecontrol study.The expression rate of CD269 and CD317 in bone marrow blood of 35 patients with iron deficiency anemia and other antigens in bone marrow blood of 63 patients with MM were detected by flow cytometry.The levels of serum hemoglo bin (Hb),serumβ2-MG(β2-MG) and lactatedehydrogenase (LDH) in patients with MM were dctectcd,and the levels of CD269 and CD317 were analyzed statistically.Results The positive rates of CD269 in the study group and control group were (86.6±2.35)％ vs (4.33±l.69)％,rcspectivcly (t =4.256,P＜0.05)).The positive rate of CD317 was (71.42+ 0.62)％ vs (8.32+ 3.89)％,the difference was statistically significant (t=3.102,P＜0.05).In other expression,the expression level of CD269 and CD317 in CD56 positive group was significantly higher than that of negative group (t=4.032,P＜0.05),while the expression of CD117 the level of positive group was significantly lower than that of the negative group (t 2.832,P＜0.05),CD19,CD20 expression was not statistically significant difference between the two groups (P＞ 0.05).The levels of CD269 and CD317 in patients with MM were positively correlated with the level of CD56 expression (r =0.392,P＜0.05),and negatively correlated with the level of CD117 expression (r=-0.210,P＜0.05).The levels of CD269 and CD317 in patients with MM were significantly lower than those in the negative group (t=3.012,P＜0.05) and the levels of serum LDH in the positive group were lower than those in the negative group (t=2.024,P＜0.05).There was a negative correlation between Hb content (r=-0.212,P＜0.05) and negatively correlated with serum β2-MG (r=-0.312,P＜0.05).Conclusion The high expression of CD269 and CD317 in bone marrow cells in MM patients is related to the increase of CD56 and decrease of CD117 in patients with MM.
ABSTRACT
Objective To explore the differential expression of CD269 and CD317 in patients with multiple myeloma(MM). Methods Newly diagnosed samles from patients of MM(20 cases)and iron deficiency anemia(20 cases),40 cases in total (from 06/2015 to 08/2013,the Department of Hematology,Central Hospital of Zhuzhou City)were collected.Real-time quantitative PCR(RQ-PCR)tests were used to detect the relative expression of CD269 and CD317 in bone marrow sam-ples,and the results were statistically analyzed with clinical features.Results The relative expression levels of CD269 and CD317 in patients with multiple myeloma(4.418±4.568,4.327±2.876)were significantly higher than those in the control group(0.600±0.838,1.033±1.335),the difference was statistically significant(t=3.676,4.646,all P<0.05)respective-ly,while not related with the gender,age(P>0.05).There was no correlation between the expression of CD269 and CD317 (r=0.041,P=0.864),but positively correlated with the ratio of myeloma cells(r=0.495,P=0.026;r=0.533,P=0.016).Conclusion CD269 and CD317 were highly expressed in patients with multiple myeloma and may be involved in the pathogenesis of multiple myeloma.
