Cell count of NK cells between the two groups. On POD 1, in both two groups, the count of NK cells significantly descended (P < 0.05). While on POD 4, the count of NK cells in OCR group still had continuous depression trend compared with LCR group (P > 0.05). On POD 7, the count of NK cells still less than the preoperative level in both two groups (P < 0.05), but there was no difference between the two groups.
