METHODS:We compared the immune adherent properties of red blood cells (RBCs),the expression of metastasis protein CD44,and the metastasis inhibition factor nm23,in esophageal carcinoma tumor cells of patients before and after radiotherapy in the presence and absence of orally administered Fuzheng Yiliu granules. Sixty-three hospitalized patients with esophageal carcinoma were treated with standard radiotherapy and randomly divided into treatment group (n = 30) treated with both radiotherapy and Fuzheng Yiliu granules and control group (n = 33) given radiotherapy only. Blood samples and tumor tissue were obtained before and after 21 d of treatment. The rosette rates for complement receptor type 3b (C3bRR) and immune complex receptor (ICRR) on RBCs were measured by erythrocyte immunological methods. Expression of CD44 and nm23 in tumor tissue sections was determined by immunohistochemical staining with monoclonal antibodies CD44v6 ad nm23H-1,respectively. RESULTS:The positivity of RBC-C3bRR before and after 21 d of treatment increased from 7.78% ± 1.59% to 10.03% ± 2.01% in the double treatment group,while it changed only slightly from 7.18% ± 1.29% to 7.46% ± 1.12% in the radiotherapy group. The positive rate for RBC-ICRR decreased from 37.68% ± 2.51% to 22.55% ± 1.65% after the double treatment,and from 37.28% ± 2.41% to 24.69% ± 1.91% in radiotherapy group at the same time points. The difference in erythrocyte immune adherent function between the two groups was significant (P < 0.01,t-test). The CD44+-cases were reduced from 21 (70.00%) to 12 (40.00%) after treatment with Fuzheng Yiliu granules,whereas the CD44+-cases (69.70%) in the radiotherapy group remained unchanged. The difference between the treatment (40.00%) and control (69.70%) groups was significant (P < 0.05). Although the nm23+-cases were increased from 4 (13.33%) to 6 (20.00%) in the double treatment group and from 6 (18.18%) to 7 (21.21%) in the radiotherapy group,the difference was not significant (P > 0.05). CONCLUSION:Fuzheng Yiliu granules enhance the immune adhesion function of RBCs and reduce the number of CD44+-cells in esophageal carcinoma patients,suggesting a potential role of these Chinese herbals in suppression of invasion and metastasis of malignant cells. However,this anti-metastatic effect has yet to be validated in vivo.展开更多
