Objective To evaluate the anesthetic efficacy of different doses of dexmedetomidine combined with ketamine in the pediatric patients undergoing closure of ventricular septal defect.Methods Ninety pediatric patients with ventricular septal defect requiring interventional treatment,aged 4-11 yr,weighing 12-47 kg,of ASA physical status Ⅰ or Ⅱ,were randomly divided into D1-3 groups (n =30 each) using a random number table.After admission to operating room,anesthesia was induced with iv atropine 0.02 mg/kg and ketamine 1.0 mg/kg,followed by administration of a loading dose of dexmedetonidine 0.5 μg/kg which was infused over 10 min.In D1,D2 and D3 groups,dexmedetomidine 0.7,1.0 and 1.2 μg· kg 1 · h-1 were infused intravenously,respectively,until the end of operation.After the pediatric patients lost consciousness,the femoral artery was punctured to perform interventional treatment.Additional ketamine 0.5 mg/kg was given when the depth of anesthesia was inadequate.BIS,BP,HR and SpO2 were recorded after admission to the operating room (T0),at 1 and 5 min after ketamine administration (T1,2),at the end of loading dose of dexmedetomidine infusion (T3),at 15 min after maintenance dose of dexmedetomidine infusion (T4),immediately after operation (T5),and immediately after emergence (T6).The total consumption of ketamine,cases who needed additional ketamine and atropine,operation time,emergence time and development of adverse effects such as respiratory depression and postoperative agitation were recorded.Results Compared with the baseline value at T0,BIS value was significantly decreased at T4,5 in the three groups,HR was decreased at T4,5 in D2,3 groups,and no significant change was found in BP and SpO2 at each time point in the three groups.Compared with D1 group,the requirement for additional atropine was significantly increased,the total consumption of ketamine was reduced,and the requirement for additional ketamine and incidence of respiratory depression were decreased in D2 and D3 groups.No patients needed additional ketamine in D2 and D3 groups.The requirement for additional atropine was significantly higher in D3 group than in D2 group.There was no significant difference in the operation time and emergence time among the three groups.No pediatric patients developed agitation during emergence from anesthesia.Conclusion Ketamine 1.0 mg/kg (for induction of anesthesia) combined with a loading dose of dexmedetomidine 0.5 μg/kg and maintenance dose of dexmedetomidine 1.0 μg·kg-1 · h-1 (for maintenance of anesthesia) can produce good anesthetic efficacy,which is an optimum combination of anesthesia in pediatric patients undergoing closure of ventricular septal defect.

Objective To approach the effect of protective mechanical ventilation on acute lung injury after orthotopic liver transplantation, by observing changes of plasma markers of lung injury and inflammatory mediators.Methods Sixty patients scheduled for liver transplantation under general anesthesia, 42 males and 18 females, aged 21-62 years, weighing 43-80 kg, ASA physical status Ⅱ-Ⅳ, were randomly divided into 2 groups: protective mechanical ventilation group (group P) and unprotective mechanical ventilation group (group U).Pulmonary artery blood for plasma markers of lung injury and inflammatory mediators were collected at the following time points: before operation (T1), 3 hours after mechanical ventilation (T2), 2 hours (T3) and 4 hours in neohepatic stage (T4).These mediators included clara cell secretory protein (CC16), surfactant proteins (SP-D), soluble receptor for advanced glycation end-products (sRAGE), TNF-α, IL-6 and IL-8.Moreover, blood gas results were recorded at these 7 time points: T1-T4, 2 hours after operation (T5), before tracheal extubation (T6) and 2 days after operation (T7).The postoperative awakening time, tracheal extubation time, ICU stay time and the incidence of ALI were recorded.Results Compared with T1, plasma level of CC16 in the two groups increased at T2 and T3 (P<0.05 or P<0.01), however, plasma level of SP-D, sRAGE, TNF-α, IL-6 and IL-8 did not increase until T3 (P<0.01).Moreover, plasma level of sRAGE, TNF-α, IL-6 and IL-8 at T4 were higher than those at T1 (P<0.05 or P<0.01).Compared with T1, OIs in the two groups increased at T2, T5 and T6 (P<0.05 or P<0.01), while decreased at T4 in group P (P<0.01) and at T3 and T4 in group U (P<0.01).In group P, patients showed a lower plasma level of CC16 at T2 and T3 (P<0.05 or P<0.01), a higher OI at T3 (P<0.05) and an earlier tracheal extubation after operation [(8.9±3.2) h vs (9.3±2.8) h, P<0.05] compared with group U.There was no significant difference of acute lung injury incidence between the two groups after operation, which was 5(16.6%) and 7 (23.3%), respectively.Conclusion Protective mechanical ventilation may promote oxygenation index, and shorten tracheal extubation time, thus protect lung function of patients in liver transplantation to some extend.

Objective To explore the immunophenotype of children with acute myeloid leukemia(AML) and its clinical significance.Methods Statistics was used to analyze the relationship between the immunophenotype of AML and their French-American-Britain(FAB) classification,complete remission (CR) in one month and 3-years event-free survival(EFS).Results CR rate was 71.6% and 3-years EFS rate was 50.8%. HLA-DR and CD34 absent mainly in M3, associated with higher CR and EFS rate. So did CD33 negative cases, especially in M2. CD13 positive was significantly predictive factor for achieving CR.Co-expression of lymphoid antigens and NK cell antigens(CD56) with M2 which correlated with lower CR and EFS rate.Conclusions The negative of HLA-DR, CD34, CD33,as well as CD13 positive, have relationship with good prognosis. Lymphoid antigens and CD56 are poor prognostic factors.

OBJECTIVETo investigate the diagnosis and differential diagnosis of granulocytic sarcoma (GS).

METHODSThe morphological and immunological characteristics of 12 cases of GS were studied. FAB classification was made by peripheral blood, bone marrow picture and bone marrow biopsy assay.

RESULTSAll of the 12 cases presented with lymphadenopathy and soft tissue mass. Histologically, the tissue infiltration of GS was composed of blastic cells with round to oval nuclei showing an even, pale chromatin pattern. Some with cleaved or notched nuclei. There were prominent nucleoli and scant cytoplasm in the cells and mitosis was easily found. Immunohistochemically, CD(45) and lysozyme were positive in all of the cases, MPO in 11 (92%), CD(68) in 10 (83%), CD(34) in 5 (42%), and TdT in 2 cases (17%). CD(15) and Mac387 were mainly expressed in mature granulocytes. Examination of bone marrow sections and marrow aspirate smears showed that out of the 11 cases tested 8 were AML-M(2), 2 AML-M(1) and 1 AML-M(0). Only 1 case was nonleukemic, ie. solitary granulocytic sarcoma.

CONCLUSIONGranulocytic sarcomas are difficult to identify in routine paraffin-embedded tissue sections and usually misdiagnosed as non-Hodgkin's lymphomas. Immunohistochemistry study with a panel of antibodies in combination with bone marrow and peripheral blood examination are helpful in identification of granulocytic sarcoma.

To establish neonatal rat cardiac fibroblast inflammatory secretion model by using LPS 100 microg x L(-1) combined with ATP 5 mmol x L(-1), in order to study the inhibitory effect of quercetin on the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts, further investigate the effect of quercetin on the protein expression of p-NF-kappaB p65 (S276) and p-Akt (S473) by western blot, and discuss the inhibitory effect of quercetin on the inflammatory secretion of cardiac fibroblasts. According to the findings, quercetin with the concentrations between 51.74 micromol x L(-1) and 827.81 micromol x L(-1) had no significant effect on the activity of cardiac fibroblasts. Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of TNF-alpha and IL-1beta induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.01 or P < 0.05). Quercetin with the concentrations of 82.78, 41.39 micromol x L(-1) could notably inhibit the increase of IL-6 induced LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.05), without any notable effect of quercetin with the concentration of 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20. 70 micromol x L(-1) could notably inhibit the NF-kappaB p65 (S276) activation induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 15 min, with the most significant effect in 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of p-Akt(473) expression induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 240 min (P < 0.05). Therefore, this study believes that quercetin could attenuate the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts by inhibiting the activation of NF-kappaB p65 (S276) and Akt (473).

OBJECTIVEfrom the perspective of mitochondria.

METHODSTweleve SAMP8 mice aged 8 months were randomly divided into a model group (n = 6) and an electroacupuncture group (n = 6), and six SAMR1 mice aged 8 months were selected as a control group. The electroacupuncture group was treated with electroacupuncture at "Baihui" (GV 20), "Dazhui" (GV 14), "Shenshu" (BL 23) and "Taixi" (KI 3) for 20 min, once each day, 10 days for a course, and lasted for 3 courses. The other two groups were grasped and fixed in the same way at the same time without the other treatment. After the end of treatment, the learning and memory abilities of the mice were measured by Morris water maze, the activity of hippocampal mitochondrid respiratory chain enzyme complex was performed by spectrophotometry, and the levels of adenosine triphosphate (ATP) were detected by a reverse-phase high performance liquid chromatography (HPLC) method.

RESULTSCompared with the control group, the average escape latency significantly lengthened, the residence time on the plateau phase shortened, the activity of respiratory chain enzyme complexe I, II, III, and IV was decreased, and ATP concentration was decreased in the model group. Compared with the model group, the average escape latency significantly shortened, the residence time on the plateau phase lengthened, the activity of hippocampal mitochondrid respiratory chain complexes I, II, III, and IV was significantly increased, and ATP concentration was increased in the electroacupuncture group.

CONCLUSIONElectroacupuncture can increase the activity of hippocampal mitochondrid respiratory chain enzyme complexe and ATP concentration and improve mitochondrial function, which may be one of underlying mechanisms of electroacupuncture in treatment of AD.

OBJECTIVETo retrospectively analyze the treatment outcomes and side effects of childhood acute promyelocytic leukemia (APL) treated with all-trans retinoic acid (ATRA) or ATRA + arsenic trioxide (As2O3).

METHODSFrom 1992 to 2006, 45 patients with newly diagnosed APL were enrolled. All of them were PML-RAR alpha positive. 24 patients were induced with ATRA (group A) and 21 with ATRA + As2O3 (group B). The remission rate and side effects were observed.

RESULTS1) 19 (79.2%) patients in group A achieved CR, while 21(100%) patients in group B achieved CR. The CR rate in group A was lower than that in group B (P=0.027). 2) The recovery time of coagulation parameters and PLT count in group B was shorter than that in group A. 3) The overall survival (OS) and event-free survival(EFS) in group A were 77.8% and 66.9% at 41 months of follow-up, and in group B were 100% and 100% respectively at 34 months of followup. Group A had a significant lower EFS (P=0.0357)than group B. 4) The time of PML-RAR alpha fusion gene converting to negative in group A was longer (P=0.026) than that in group B.

CONCLUSIONSATRA + As2O3 for patients with newly diagnosed childhood APL is a feasible treatment with higher CR rate, less side effects and longer long-term survival.
