Objective To explore the effect of ProSeal laryngeal mask airway and endotracheal tube on analepsia stage of general anesthesia in geriatric patients undergoing radical mastectomy.Methods Thirty geriatric females with breast cancer of American Standards Association (ASA)Ⅰ-Ⅱscheduled for selective radical mastectomy under general anesthesia were randomly allocated to two groups: ProSeal laryngeal mask airway group(PLMA group, n=15) and endotracheal tube group (ET group, n=15). The patients were put on PLMA or were intubated with ET under general anesthesia in the two groups, respectively. The heart rate (HR), systolic blood pressure(SBP)and diastolic blood pressure (DBP) were recorded at the time points of 5 min after entering operation room (T0), end of surgery (T1), opening eyes (T2), after extubation (PLMA) immediately (T3) and 3 min after extubation (PLMA) (T4). The numbers of patients who were given antihypertensive agent,showed bucking, agitation or sore throat, nausea and vomiting after extubation were recorded during the analepsia stage of general anesthesia. Results The blood pressure (BP) and HR were mildly.increased in PLMA group at T2, and there was no significant difference compared with T0(P＞0.05). But the BP and HR were significantly higher at T3 than at T0 (P＜0.05). In ET group, the BP and HR were both significantly elevated at T2 and T3 than at T0 (P＜0.05), and reached the peak at T3. The increased levels of BP and HR were significantly lower in PLMA group than in ET group at T2 and T3 (P＜0.05). The quantities of patients who were given antihypertensive agent, showed bucking and sore throat were less in PLMA group than in ET group(P＜0.05). No differences in incidence rate of agitation, nausea and vomiting after extubation between the two groups were observed(P＞0.05). Conclusions PLMA can obviously reduce the occurrence of complications in analepsia stage of general anesthesia in geriatric patients scheduled for selective radical mastectomy,and is beneficial to provide much safer anesthesia.

BACKGROUND:Mesenchymal stem cells are capable of self-renew,a high degree of proliferation,with multi-differentiation potential,low immunogenicity and immunomodulatory properties.Both in vivo and in vitro it is able to regulate allogeneic immune response,to induce immune tolerance.In the solid organ transplantation it is playing an increasingly important role.OBJECTIVE:To summarize the research progress on the immunomodulatory mechanism and application of mesenchymal stem cells in solid organ transplantation.METHODS:An online search of Pubmed was undertaken by using the key words of "Mesenchymal Stem Cells,Mesenchymal Stem Cell Transplantation,Organ Transplantation,Transplantation Immunology,Immunologic Graft Enhancement,Graft vs.Host Disease" in Mesh to identify the relevant articles published in English from January 1994 to October 2009.At the same time,Wanfang database was screened to identify the relevant articles published between January 1994 and October 2009 with the key words of "Mesenchymal Stem Cells,Organ Transplantation,Transplantation Immunology" in Chinese.Inclusive criterion:The articles related to the immunomodulatory properties,transplantation immunology and application of mesenchymal stem calls in the solid organ transplantation were included.Exclusive criterion:The articles with repetitive research or Meta analysis were excluded.RESULTS AND CONCLUSION:Totally 200 relevant articles were selected and 86 of them met the inclusive criterion.Mesenchymal stem cells exhibit low immunogenicity and immunomodulatory properties,have an indispensable advantage about inducing graft tolerance and repairing tissue in solid organ transplantation.The mechanism of inducting immune tolerance may be related to soluble factors,regulatory T cells,tolerant dendritic cells,bone marrow chimerism,anti-inflammatory and tissue repair,dose and time of injecting MSCs.

Objective To assess the efficacy and safety of target-controlled infusion of propofol and remifentanil in geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation. Methods Thirty geriatric patients with primary hepatocellular carcinoma of ASA Ⅱ-Ⅲ scheduled for percutaneous radiofrequency ablation under monitored anesthesia care (MAC) were randomly allocated to two groups: target-controlled infusion of propofol and remifentanil group (PR group, n= 15) and intravenous injection of midazolam and fentanyl group (MF group. n= 15). The mean arterial blood pressure (MAP), heart rate (HR) and pulse oxygen saturation (SpO2) of patients were recorded during the treatment. The Ramsay Score, Patient Cooperation Score, VAS Score and postoperative Patient Satisfaction Score were recorded as well. Results The Ramsay Score, Patient Cooperation Score, VAS Score and Patient Satisfaction Score were all higher in PR group than in MF group (all P<0.05). The maximum values of MAP and HR [( 108.7± 8.6) mm Hg, (83.8±7.1) times/min] were significantly higher than the baseline values [( 99.3 ± 8.5) mm Hg, (76.3±7.1) times/min] in MF group, and the degree of increment of MAP and HR were significantly greater in MF group than in PR group (both P<0.05). The minimum values of MAP and HR [(84.5±6.5) mm Hg, (66.6 ± 6.6) times/min] were significantly lower than the baseline values [(97.7±6.5) mm Hg, (75.4±7.3) times/min] in PR group, and the degree of decrement of MAP and HR were significantly greater in PR group than in MF group (both P<0.05). SpO2 of both groups decreased significantly (the minimum values of PR and MF groups were 95.1±2.0 and 95.5± 2.2, respectively), but there was no statistical difference between two groups (P>0.05) . Conclusions MAC with target-controlled infusion of propofol and remifentanil is more suitable for geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation, as it can provide ideal analgesia and sedation, but the respiration and the change of hemodynamics of patients must be observed seriously.
