Abstract:
Objective:To analyze the changes of peripheral blood CD 4+ T lymphocyte subsets caused by nanosecond pulse ablation in C57BL/6J liver cancer mice and its effect on the immunity of liver cancer mice. Methods:According to the randomallocation, 32 female C57BL/6J mice weighing 18-20 g and aged 8-10 weeks were divided into the blank control group (Group A), the liver cancer control group (Group B), the radical liver lobectomy group (Group C), and the nanosecond pulse ablation treatment group (Group D), with 8 mice in each group. The in situ liver cancer models for mice in groups B, C, and D were established using Hepa 1-6 hepatoma cell line. On the 7th day after modeling, group C underwent liver lobectomy, and group D underwent nanosecond pulse ablation. After 7 days of treatment, the subtypes Th1, Th2, Th17 and Treg cell levels of CD 4+ T cells in the peripheral blood of the four groups of mice were detected by flow cytometry. Results:Flow cytometry was used to detect and analyze the proportions of CD 4+ T cell subsets Th1, Th2, Th17 and Treg in the peripheral blood of four groups of mice. Comparisons of each index among the groups showed statistically significant differences (all P<0.001). The proportion of Th1 cells detected by flow cytometry was (8.4±1.1) % in group A, (8.5±1.5)% in group D, (3.5±0.5)% in group B, and (2.4±0.5)% in group C. Both group A and Group D were higher than group B and group C, and the differences were statistically significant (all P<0.001). The proportion of Th2 cells detected by flow cytometry was (5.1±0.8)% in group A, (5.1±1.3)% in Group B, (5.4±0.9)% in group C, and (3.6±0.9)% in group D. The proportion of Th2 cells in groups A, B, and C was higher than that in group D, and the differences were statistically significant (all P<0.05). The proportion of Th17 cells detected by flow cytometry was (1.5±0.6)% in group A, (8.6±1.3)% in group B, (8.2±1.5)% in group C, and (1.7±0.3)% in group D. The proportion of Th17 cells in both group B and group C was higher than that in group A and group D, and the differences were statistically significant (all P<0.001). The proportion of Treg cells detected by flow cytometry was (7.0±0.9)% in group B, (6.8±0.9)% in group C, (3.8±0.8)% in group D, and (0.9±0.2)% in group A. The proportion of Treg in group B and group C was higher than that in group A and group D, and the difference was statistically significant (all P<0.001). Conclusion:Nanosecond pulse ablation for liver cancer in mice can regulate CD 4+ T cell subsets in peripheral blood, enhance the immune response of Th1 cells, inhibit the expression of Th2, Th17 and Treg cells, and improve the immunosuppressive state caused by liver cancer.
