Abstract:

Objective To observe the effect of acute normovolemic hemodilution(ANH) combine with low central venous pressure(LCVP) on regulatory T cells and natural killer(NK) cells in patients undergoing liver cancer resection. Methods The Sixty-six patients undergoing right liver cancer operation operated by the same surgeon were equally randomized into three groups ANH, LCVP, or ANH+LCVP, respectively. Peripheral venous blood was extracted on postoperative days 0(T0), 1(T1), 3(T2), 5(T3) to determine immune function including regulatory T cells and NK cells.

Compare with the A+L group, the levels of CD4+CD25+[(12.1±2.9),(12.4±3.3),(10.8±3.9) and(13.3±2.9),(13.0±3.8),(12.6±4.3)] and CD25+FOXP3+ [(5.4±1.5),(5.2±1.8),(4.6±1.9) and(6.0±1.9),(5.5±2.0),(4.9±1.7)] increased in the L and A groups, CD8+ [(16.5±3.1),(18.6±6.3),(19.2±6.9)] decreased in the A group at T1, T2 and T3, the levels of CD8+[(18.9±4.0),(20.5±5.0)] and CD4+CD25-[(32.4±5.3),(34.6±6.2)] decreased in the L group, CD4+CD25-[(31.2±6.5),(31.8±6.8)] decreased in the A group, NK cells [(11.4±4.2),(12.5±4.8) and (11.2±4.7),(11.0±5.3)] decreased in the L and A groups at T2 and T3(P<0.05). In the patients of non-allogeneic transfusion: compare with T0, the levels of CD4+CD25+ [(9.0±1.4),(8.3±1.3) and (9.4±1.8),(8.5±1.3)] and CD25+FOXP3+[(3.6±0.7),(3.4±0.7) and (3.7±0.8),(3.4±0.8)] decreased, CD8+[(23.7±3.8),(26.9±2.8) and (24.3±3.2),(25.61±3.0)] and CD4+CD25?蛳[(36.7±3.1),(38.0±1.9) and(37.3±2.5),(38.2±2.4)] increased at T2 and T3, NK cells[(12.8±2.8) and(13.4±3.6)] decreased at T1 in the A+L group and A groups, the levels of CD4+CD25+(8.6±1.4) and CD25+FOXP3+(3.7±1.0) decreased, CD8+(23.3±2.5) and CD4+CD25?蛳(38.1±2.3) increased at T3, NK cells(13.8±3.2),(13.2±3.5)] decreased at T1 and T2 in the L group(P<0.05). Compare with the A+L group, the levels of CD4+CD25+(10.9±2.5) and CD25+FOXP3+(4.3±1.0) increased, NK cells(13.2±3.5) decreased at T2, CD8+ [(20.7±3.0),(23.3±2.5)] decreased at T2 and T3 in the L group(P<0.05). However, the alterations of T lymphocyte subsets and NK cells in the A group were not significant difference at each time points(P>0.05). Conclusions In liver cancer operations, ANH combine with LCVP can rapidly improve postoperative immune functions and NK cells immune regulatory functions.
