The application of dexmedetomidine combined with dezocine in thoracoscopic radical resection of lung cancer and its effect on awakening quality of patients

Analysis of Anesthesia Effect of Dexmedetomidine in Clinical Operation of Replantation of Severed Finger

Brachial plexus block commonly used in finger replantation has the advantages of simple operation, small side effects, and stable circulation, but it has inherent problems such as imperfect block range, slow onset of anesthesia, and short maintenance time of anesthesia. In order to explore the reliable clinical anesthesia effect, this paper uses experimental investigation methods to study the effect of dexmedetomidine in clinical surgery of replantation of severed fingers. Moreover, this paper uses comparative test methods, uses statistical methods to process test data, and uses intuitive methods to display test results. Finally, this paper verifies the reliability of dexmedetomidine in replantation of severed finger through comparative analysis and verifies that the anesthesia method proposed in this paper has certain user satisfaction through parameter survey.

Dezocine promotes T lymphocyte activation and inhibits tumor metastasis after surgery in a mouse model

Dezocine is an opioid analgesic with both μ-receptor agonist and antagonist activities. Administration of opioids influences the immune system through immune cells. Dendritic cells (DC) play crucial functions in inducing T cell response and mediating immune functions. DC surface displays several different opioid receptors whose expression is induced during DC maturation. We aimed to explore the effects of dezocine on DCs and T cells, as well as on tumor treatment. Mice were intraperitoneally administrated with increasing doses of dezocine (0.75, 1.25 and 2.0 mg/kg). Mouse bone marrow-derived dendritic cells (BMDCs) were then isolated from the bone marrow. The BMDC surface markers were evaluated by flow cytometry. T cell proliferation was assessed by the carboxyfluorescein succinimidyl ester assay. The number of mature DCs were increased by dezocine treatment in both human umbilical cord blood and mouse peripheral blood, suggesting that dezocine enhanced BMDC maturation. Dezocine-treated BMDCs promoted CD8+ T cell proliferation and cytotoxicity, while dezocine treatment inhibited tumor metastasis in mice. We therefore conclude that the administration of dezocine promotes BMDC maturation and inhibits tumor metastasis through elevating CD8+ T cell proliferation and cytotoxicity.
