Table 4 Changes of IL-2, IL-6 and TNF_α after surgery in two groups (mean ± SD)

		LTME n = 20	OTME n = 25	P value
IL-2(ng/L)	d1	-80.54 ± 304.30	-98.82 ± 412.38	0.869
	d5	-27.55 ± 344.29	-33.59 ± 560.20	0.967
IL-6(ng/L)	d1	-23.14 ± 263.97	27.38 ± 129.14	0.405
	d5	-40.08 ± 272.03	21.67 ± 234.31	0.418
TNFα (ng/L)	d1	2.23 ± 12.78	-1.01 ± 7.82	0.301
	d5	1.84 ± 12.84	0.56 ± 9.86	0.705

(d₁ = the differences of the values of IL-2, IL-6 and TNF_α on the first postoperative day subtracted those before operation, respectively. d₅ = the differences of the values of IL-2, IL-6 and TNF_α on the fifth postoperative day subtracted those before operation, respectively).
