In this paper, the representation theorems of L-fuzzy rough sets based on residuated lattice are given. The properties and axiomatic definition of the lower and upper approximarion operators in L-fuzzy rough sets are discussed.展开更多

The levels of T cell subsets, T cell cytokine and immunoglobulin in the observation group before and after operation were detected and compared with those in the control group.Results:The CD3+, CD4+ and CD4+/ CD8+ of the observation group before operation were lower than those of the control group, and CD8+ was higher than that of the control group, the differences were statistically significant. The CD3+, CD4+ and CD4+/CD8+ after operation in the observation group were (64.98 ± 3.88)%, (42.40 ± 3.53)% and (1.56 ± 0.41) respectively, which were all higher than those before the operation, but still lower than those in the control group. The CD8+ of the observation group was (27.25 ± 3.54)% lower than that before operation, but it was still higher than that of the control group. In the observation group, the levels of INF-γ+, CD4+/INF-γ+, IL-2+, and CD4+/IL-2+ before operation were lower in the observation group than those in the control group. In the observation group, INF-γ+, CD4+/INF-γ+, IL-2+, and CD4+/IL-2+ after surgery were (0.15±0.06)%, (0.07±0.03)%, (0.47±0.13)%, (0.16 ± 0.11)%, were higher than those before surgery, but still lower than those in the control group. The IgA and IgG before and after the surgery in the observation group were (2.01±0.13) g/L, (1.81±0.12) g/L, (10.53±3.12) g/L, and (8.41±2.01) g/L, respectively, compared with the control group, the difference was statistically significant. There was no significant change in IgA, IgG and IgM in the observation group before and after operation.Conclusion:Surgery can effectively improve the T lymphocyte subsets and T cell cytokine levels in oral cancer patients, and has a positive effect on improving immune function.展开更多
