Expression of sB7-H4 in Serum and Lymphoma Tissues of Patients with Malignant Lymphoma and Its Value for Diagnosis and Re-Examine of Lymphoma / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the soluble B7-H4 (sB7-H4) expression in serum and lymphoma tissues of patients with malignant lymphoma (ML) and its value for diagnosis and re-examination lymphoma.</p><p><b>METHODS</b>The serum samples from 83 cases of ML were collected, among them 69 cases of newly diagnosed ML were enrolled in group A including 11 cases of Hodgkin's lymphoma (NHL group) and 58 cases of non-Hodgkin's lymphoma (NHL group), the serum samples from 14 cases of relapsed ML were enrolled in group B; at the same time the serum samples of 50 healthy persons conformed by physical examination were collected and enrolled in control group. The double antibody sandwich ELISA was used to detect the serum level of sB7-H4 in each group, and immunohistochemistry method was used to detect the expression of sB7-H4 in malignant lymphoma and reactive lymphoid hyperplasia tissues.</p><p><b>RESULTS</b>The serum level of sB7-H4 in the group A was significantly increased in comparison with the group B and control group, and the level of group B was significantly higher than that in the control group (P<0.05); the serum level of sB7-H4 in the NHL group was significantly increased in comparison with HL group and control group, and the level of HL group was higher than that of control group (P<0.05). The expression of sB7-H4 in reactive lymphoid hyperplasia tissues was negative, but the positive expression rate in malignant lymphoma tissues was 47.50%, suggesting the positive rate of sB7-H4 in malignant lymphoma tissues was significantly higher than that of reactive lymphoid hyperplasia tissues (P<0.05).</p><p><b>CONCLUSION</b>The high expression of sB7-H4 in serum and lymphoma tissues of patients with malignant lymphoma has a certain value for the diagnosis and re-examination of patients with malignant lymphoma.</p>
