Methods: In our hospital from July 2016 to June 2017 undergoing radical mastectomy for breast cancer of 88 patients were randomly divided into observation group and control group of 44 cases, 2 patients underwent routine preoperative preparation, and routine blood pressure, heart rate, pulse, oxygen saturation, ECG monitoring, control group with intravenous anesthesia. The observation group was treated with epidural block combined with intravenous anesthesia. 2 groups of patients before anesthesia, 30 MIM (T0), 1 h after skin incision (T1), 4 h after operation (T2), 24 h after operation (T3), 48 h after operation (T4) from peripheral venous blood were measured by interleukin-8 (IL-8) and interferon gamma (IFN-γ), cortisol (Cor), prolactin (PRL), growth hormone (GH) and T lymphocyte subsets (CD3+, CD4+, CD8+), the calculation of CD4+/CD8+ value. Results: the serum IL-8 level of T1, T2, T3and T4 decreased gradually, were lower than at T0, and the control group at each time point had no significant difference, T1, T2, T3group, T4IL-8 levels lower than the control group;the 2 groups of serum IFN-γ levels T1 and T2had no significant change, T3and T4increased gradually, was higher than that of T0, but no significant difference between the 2 groups of IFN-γ levels. 2 serum Cor levels peaked at T1, decreased at T2, was higher than that of T0, T3, T4returned to T0, the observation group T1, T2Cor level lower than the control group;the serum PRL levels of 2 groups reached a peak at T1, T2, T3at the time of T4decreased gradually, was higher than that of T0, T1, T2, T3of the observation group at the PRL level is lower than the control group;the serum level of GH 2 in group T1increased gradually, reached a peak at T2, T3and T4 decreased gradually, was higher than that of T0, the observation group T1, T2, T3, T4, GH levels lower than the control group. 2 groups of CD3+ decreased gradually in T1, T2, were lower than T0, T3, T4returned to T0, the observation group T1, T2CD3+ was higher than the control group;group CD4+ decreased gradually in T1, T2, T3and T4were lower than control, T0when, and the observation group CD4+ in T1, T2, T3, T4, no significant changes were observed in group T1, T2, T3, T4and CD4+ higher than that of the control group;the 2 group CD8+ had no obvious changes in T1, T2, T3, T4;observation group CD4+/CD8+ decreased gradually in T1, T2, were lower than T0, T3, T4returned to T0, the observation group T1, T2CD4+/CD8+ was higher than the control group. Conclusion: epidural block combined with intravenous anesthesia for breast cancer radical mastectomy can effectively relieve the stress and inflammatory reaction, alleviate the immunosuppression, and help to restore the postoperative immune function.展开更多

Methods: In our hospital from July 2016 to July 2017 undergoing radical mastectomy for breast cancer were studied in 79 patients, were randomly divided into observation group and control group. Two groups of patients with routine preoperative preparation, monitoring blood pressure, electrocardiogram, heart rate, pulse, oxygen saturation, establish vein channel, using propofol, remifentanil, vecuronium induced anesthesia, observation group before induction of anesthesia, dexmedetomidine 1 μg/kg, 10 min after infusion, followed by 0.5 μg/kg/h continuous infusion to the end of the operation, the control group with normal saline continuous infusion till the end of the operation. Two groups of patients before induction of anesthesia (T0), at the end of operation (T1), 6 h after operation (T2), 24 h after operation (T3), 72 h after operation (T4) from peripheral venous blood determination of interleukin-2 by ELISA method (IL-2), interleukin-4 (IL-4), interleukin-10 (IL-10) and interferon gamma (IFN-γ), calculated IFN-γ/IL-4 in T0, T2, T3, T4from peripheral blood. CD3+, CD4+, CD8+, NK cells were determined by flow cytometry and CD4+/CD8+ were calculated. Results: Two groups of IL-2 and IFN- in T1, T2, T3gamma, T4is higher than T0, IL-10 less than T0, and the observation group IFN-γ/IL-4 is higher than T0, the control group was lower than that of T0when compared with T0significant difference, 2 in group IL-4 had no obvious changes were observed in group IL-2;IFN-γ, IFN-γ/IL-4 in T1, T2, T3, T4higher than the control group, IL-10 was lower than the control group, significant difference between the 2 groups. CD3+, CD4+, CD4+/CD8+, NK cells in T2group was lower than that of T0, T3, and CD8+ had no obvious change, compared with T0significant difference;the observation group CD3+, CD4+, CD4+/CD8+, T2, T3in NK cells was higher than the control group, significant difference between the 2 groups. Conclusion: Dexmedetomidine can inhibit the stress response during the perioperative period of radical mastectomy, correct the balance disorder of Th1/Th2, improve the level of T lymphocyte subsets, and exert better immune protection function.展开更多
