ABSTRACT
Objective To explore the difference of the level of Th1/Th2 balance and change of CD4+ CD45R cell after treated by laparoseopy-assisted rectal cancer surgery and conventional open rectal cancer surgery, so to compare the effect of the two procedures on immunity function of the patients. Methods CD4+ IFN-γ+ T cell (Thl cell), CD4+ IL-4 + T cell( Th2 cell)and the ratio of Th1/Th2 were detected by flow cytometery ; The levels of IFN-γand IL-4 were measured by ELISA. The changes of CD4 + CD45RA+ T cell and CD4+ CD45RO+ T cell were detected in the different procedures so that the effect of the two procedures on eytoimmunity and immune balance were analyzed. Results Compared with baseline levels, the level of Th1 cells was decreased [ (4.51±1.52 ) %, (7.26 ±2.59) % vs. ( 12.06 ±1.82 ) % ] (P < 0.05 ) ; The level of Th2 cells was increased [ (6.70 ± 2.41 ) %, (6.70 ± 2.41 ) % vs. (4.47 ± 1.90) % ] ( P < 0.05 ) ; The level of IFN-γ was decreased [ (57.15± 23.64) ng/L, (72.70 ± 27. 31 ) ng/L vs. ( 123.47 ± 32. 52) ng/L ] ( P < 0. 01 ) ; The level of IL-4 was increased [(55.55±7.29)ng/L,(57.56 ±7.13)ng/L vs. [(41.87±5.83)ng/L] (P<0.05) on 2nd and 7th day after conventional open reeatal cancer surgery; The level of Thl, Th2, IFN-γ and IL-4 in the laparoscopy-assisted rectal cancer surgery was not different ( P > 0.05 ). At 7 day postoperatively, the level of the CD4+ CD45 RA+ T cells was in-creased (35.11 ±7.82) and the CD4+ CD45RO+T cells was decreased(61.21±9.13) compared with surgery be-fore(31.11±6.72) and (68.11 ±11.42) respectively (P< 0.05). Conclusions The laparoscopy-assisted rec-tal cancer surgery has less influence on immune balance, thus protect systemic cell immunity.
