Relationship Between Myeloid-derived Immunosuppressive Cells (MDSC) and Dialectical Relationship of TCM with Primary Liver Cancer / 世界科学技术-中医药现代化

ABSTRACT

Objective: To explore the dialectical relationship between immunosuppressed cell expression and TCM inpatients with liver cancer. Methods: The clinical data of 237 HBV-related primary liver cancer patients were collectedand the differences of MDSC expression and clinical BCLC stage and intrahepatic metastasis were analyzed. Peripheralvenous blood was taken for the detection of MDSC (CD33/CDl4/HLA-DR-/low/CDllb) expression in mononuclear cells, helper T cells (Th1, Th2) and interleukin (IL-12, IL-4) ) detection. Results: There was a significant difference betweenliver stagnation and spleen deficiency syndrome (24.21％) and qi stagnation and blood stasis syndrome (5.54％) (Χ2=11.544, P ＜ 0.05) . The expression of MDSC (21.03％) was higher than that of liver-kidney yin deficiency (5.10％) in advanced hepatocellular carcinoma (＞ 5 cm) (Χ2= 8.223, P ＜ 0.005); the expression of Th2 in liver stagnation and spleendeficiency was higher than that of qi stagnation. There was a significant difference between groups in blood stasis group (t = 10.341, P ＜ 0.05) . The expression of Th2 in wet sputum was higher than that in liver and kidney yin deficiency group.There was significant difference between groups (t = 16.307, P ＜ 0.01) . The IL-4 in liver stagnation and spleendeficiency group (76.57 ± 5.01) was higher than that in qi stagnation and blood stasis group (121.70 ± 6.22); There was asignificant difference between groups (t = 21.414, P ＜ 0.05) . There was a significant difference in IL-4 (375.12 ± 5.31) inthe liver-kidney yin deficiency group compared with the group with wet phlegm (115.46 ± 4.15) (t = 12.455, P ＜ 0.05) .Conclusion: MDSC participates in tumor proliferation, invasion and metastasis by regulating Th2 and IL-4, which isclosely related to the dialectical classification of TCM.
