^aP < 0.05, compared with admission within the same group.

^bP < 0.05, compared with the control group.

HR: Heart rate; MAP: Mean arterial pressure.

Group	CD3+		CD4+		CD8+		CD4+/CD8+
	The 1 day before surgery	After surgery	The 1 day before surgery	After surgery	The 1 day before surgery	After surgery	The 1 day before surgery	After surgery
Observation group	52.43 ± 4.18	51.80 ± 4.20	36.10 ± 6.25	35.92 ± 6.20	24.10 ± 2.18	24.84 ± 2.36	1.50 ± 0.28	1.48 ± 0.26
