The aim of the present study was to investigate the impact of laparoscopic left hepatectomy (LLH) for hepatolithiasis on the T lymphocyte immune changes of elderly patients and to analyze underlying mechanisms of action behind these changes. A total of 164 patients who underwent LLH due to left-sided hepatolithiasis were recruited. In terms of T lymphocyte immune changes, it was found that firstly, the basic quantity of peripheral lymphocytes in the elderly group was significantly lower than that in a younger preoperative group. Secondly, after surgical trauma, the immune function of T lymphocytes had a significant decline and lasted longer when compared with younger patients, which was reflected by the perioperative changes in the T lymphocyte proliferative ability, levels of IL-2 secreted by T lymphocytes and the percentage of CD3 /CD4 T lymphocytes in the peripheral blood. Circular RNA (circRNA) 102911 (102911) was upregulated and microRNA (miR)-129-5p was downregulated in CD3 /CD4 T lymphocytes from elderly patients with LLH for hepatolithiasis. Furthermore, the overexpression of 102911 inhibited the proliferation of CD3 /CD4 T lymphocytes as well as promoting cell apoptosis, with the opposite effects being observed on knockdown of 102911. miR-129-5p is involved in the proliferation and apoptosis of CD3 /CD4 T lymphocytes and may be a promising target of 102911. Moreover, SOX6 is a downstream molecule of miR-129-5p. Immune function and number of T lymphocytes decreased significantly after surgical trauma compared to younger patients, and this decline lasted longer in older patients treated with LLH for hepatolithiasis. The 102911/miR-129-5p/SOX6 axis was found to be involved in T lymphocytes immune function, which provided a novel insight for the treatment of elderly patients with hepatolithiasis.
