Abstract
Background: To investigate whether the use of Pecs II block benefit patients with the respect to the immune functions. Methods: Totally 196 patients were included in this study. These patients were randomized to two groups, general anesthesia alone group (G group) and Pectoral nerve (Pecs) II block under general anesthesia group (PG group). Results: It was found that remifentanil consumption was less in PG group than it in G group. PG group showed a higher proportion of NK cells in peripheral blood mononuclear cell (PBMC) and an improved killing activity than G groups after surgery. We also found that postoperative interleukin (IL)-2 concentration in the plasma of PG group was dramatically higher than it of G group. Interestingly, there was even no significant change between preoperative and postoperative IL-2 levels in PG group, suggesting the less inhibitory effect of Pecs II block on immune system of those patients. Conclusions: In conclusion, these results indicate that Pecs II block use in patients may have an enhanced immunity compared with general anesthesia method. (C) 2020 Elsevier Inc.

Clonal tracking of haematopoietic cells: insights and clinical implications

Abstract
Recent advances in high-throughput genomics have enabled the direct tracking of outputs from many cell types, greatly accelerating the study of developmental processes and tissue regeneration. The capacity for long-term self-renewal with multilineage differentiation potential characterises the cellular dynamics of a special set of developmental states that are critical for maintaining homeostasis. In haematopoiesis, the archetypal model for development, lineage-tracing experiments have elucidated the roles of haematopoietic stem cells to ongoing blood production and the importance of long-lived immune cells to immunological memory. An understanding of the biology and clonal dynamics of these cellular fates and states can provide clues to the response of haematopoiesis to ageing, the process of malignant transformation, and are key to designing more efficacious and durable clinical gene and cellular therapies.
