Objective To investigate the effect of hypercapnia on cerebral oxygen metabolism under propofol anesthesia during one-lung ventilation (OLV) in patients.Methods Forty ASA physical status [or Ⅱ patients,aged 53-63 yr,scheduled for elective lobectomy performed via video-assisted thoracoscope,were enrolled in the study.Anesthesia was induced with iv injection of midazolam,fentanyl and vecuronium and target-controlled infusion of propofol and maintained with target-controlled infusion of propofol and intermittent iv boluses of fentanyl and vecuronium.BIS value was maintained at 40-60 during surgery.At 15 min of OLV,hypercapnia was performed and PaCO2 was maintained at 50-55 mm Hg lasting for 15 min,and then respiratory rate was adjusted to maintain PaCO2 at 40-45 mm Hg.Immediately before OLV (T0),at 15 min of OLV and hypercapnia (T1,2),and at 15 min after the end of hypercapnia (T3),arterial and jugular bulb venous blood samples were obtained for determination of arterial partial pressure of oxygen (PaO2),arterial oxygen saturation (SaO2),jugular bulb venous oxygen partial pressure (PjO2) and hemoglobin saturation (SjO2).The arterial to venous oxygen content difference (Da-jO2) and cerebral extraction rate of oxygen (CERO2) were calculated.Results SaO2 and PaO2 at T1-3,SjO2 and PjO2 at T1 and T3 and Da-jO2 at T2 were significantly lower and CERO2 at T1 and T3 was higher than those at T0 (P ＜ 0.05).SjO2 and PjO2 were significantly increased and Da-jO2 and CERO2 were significantly decreased at T2(P ＜0.05) and no significant changes were found in the parameters of cerebral oxygen metabolism at T3 as compared with those at T1 (P ＞ 0.05).Conclusion Hypercapnia can improve cerebral oxygen metabolism under propofol anesthesia during OLV in patients.

Objective To investigate the role of interleukin-27 (IL-27) in proliferation and differentiation of CD4+ T cells in ankylosing spondylitis(AS).Methods CD4+ T cells were separated from peripheral blood which collected from AS patients and health controls(HCs).Cells proliferation was detected by CCK-8 kit,and cytokines were analyzed by ELISA.Real-time PCR was used to determine the mRNA expression of T-bet and GATA3.Results Serum IL-27 level in patients with AS was obviously higher than that in HCs(P ＜0.01).The proliferation rate of CD4+ T cells and the level of IFN-γin cultured medium in AS were higher than those in HCs group after IL-27 stimulation (P ＜ 0.01).IL-27 could induce T-bet mRNA expression in CD4+ T cells in AS (t =14.3,P ＜ 0.01),but no change was found in GATA3 mRNA expression.Conclusions IL-27 could induce the proliferation of CD4+ T cells and the activation of T-bet pathway in AS.Furthermore,Th1 immune response and related cytokines could be induced by IL-27 in AS.These implicate that IL-27 may play an important role in AS related inflammation.

Objective Analysis of the operational efficiency trends of and problems with the public tertiary hospitals. Methods A retrospective statistics analyzed the indicators of ten public tertiary general hospitals in Shanghai during 1997-2006. Results The outpatients number per capita for the hospital staff maintains an rising trend, averaging 12.2% per year prior to year 2000; The yearly-averaged total assets turnover of the hospitals decreases from 0.89 in 1997 to 0.69 in 2003, then maintaining unchanged; The yearly-averaged receivables turnover began to fall since 1999, falling from 21.4 in 1999 to 9.7 in 2006; hospital income growth fluctuated during the years, yet with a high level of total assets growth; given the fluctuations in asset-liability ratio, such ratio has been growing slowly, maintaining at 20 % since 2004. Conclusion Problems are found with the operational efficiency of these public tertiary general hospitals as follows: the rapid growth of productivity in such hospitals finds no concurrent improvements in assets related indicators. Against a low income ratio, high debt ratio will plague hospital development to some extent.

Objective To discuss the psychological behavior intervention methods on reducing the violence behavior of schizophrenia patients. Methods 120 schizophrenia patients were admitted from January to December, 2007 and randomly assigned into the behavior intervention group (group A), the psy-chological support group (group B), the health education group (group C) and the control group (group D) with 30 cases in each group. Group A received routine nursing plus behavior intervention, group B was giv-en routine nursing plus psychological support, group C adopted routine nursing plus health education, group D only received routine nursing. The intervention effect was evaluated with MOAS and the relapse rate of violence behavior went through statistics. Results After intervention, the scores of MOAS decreased sig-nificantly in group A, B, C and D compared with those before intervention. The reduction of MOAS scores in group A, B and C was significantly higher than that of group D, with the highest reduction score in group A and group B and C followed subsequently. The relapse rates of the violence behavior in group A, B and C were significantly lower than those of group D. Conclusions Routine nursing, health education, psycho-logical support and behavior intervention can all reduce and decrease the violence behavior and the inci-dence of the violence behavior, among which behavior intervention proves to be the most effective, and psy-chological support and health education go subsequently.

Objective To determine the optimum dose of oxycodone inhibiting responses to tracheal intubation with a double-lumen endobronchial tube in patients undergoing one-lung ventilation (OLV).Methods Sixty adult patients aged 55-64 yr, weighing 60-80 kg, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective thoracic surgery requiring OLV, were randomly divided into 3 different doses of oxycodone groups (O1-3 groups, n =20 each).Anesthesia was induced with iv midazolam 0.05 mg/kg, oxycodone 0.30, 0.35 and 0.40 mg/kg (O1.3 groups, respectively) , propofol 1.5 mg/kg and rocuronium 0.9 mg/kg.The patients were tracheally intubated using a double-lumen endobronchial tube and mechanically ventilated.Before anesthesia induction (T0) , immediately before and after intubation (T1,2) , and 1 and 5 min after intubation (T3.4) , arterial blood samples were taken to determine the concentrations of serum norepinephrine (NE) and epinephrine (E) using high-performance liquid chromatography.The occurrence of bucking, body movement, hypertension, and tachycardia were observed.Results The concentrations of serum NE and E were significantly increased at T2,3 than at T1 in group O1 (P＜0.05).Compared with group O1 , the concentrations of serum NE and E were significantly decreased at T2,3 , and the incidence of bucking, body movement, hypertension, and tachycardia was decreased in O2 and O3 groups (P＜0.05).There was no significant difference in the parameters mentioned above between O2 and O3 groups (P ＞ 0.05).Conclusion The optimum dose of oxycodone inhibiting responses to tracheal intubation with a double-lumen endobronchial tube is 0.35 mg/kg in patients undergoing OLV.

Objective The coronary slow flow phenomenon (CSFP) is a coronary artery disease with a benign course,but its pathological mechanisms are not yet fully understood.The purpose of this controlled study was to investigate the cellular content of blood in patients diagnosed with CSFP and the relationship of this with coronary flow rates.Methods Coronary angiographies of 3368 patients were selected to assess thrombolysis in myocardial infarction (TIMI) frame count (TFC) values.Seventy eight of them had CSFP,and their demographic and laboratory findings were compared with 61 patients with normal coronary flow.Results Patients'demographic characteristics were similar in both two groups.Mean corrected TFC (cTFC) values were significantly elevated in CSFP patients (P ＜ 0.001).Furthermore,hematocrit and hemoglobin values,and eosinophil and basophil counts of the CSFP patients were significantly elevated compared with the values obtained in the control group (P =0.005,P =0.047,P =0.001 and P =0.002).The increase observed in hematocrit and eosinophil levels showed significant correlations with increased TFC values (r =0.288 and r =0.217).Conclusion Significant changes have been observed in the cellular composition of blood in patients diagnosed with CSFP as compared to the patients with normal coronary blood flow.The increases inhematocrit levels and in the eosinophil and basophil counts may have direct or indirect effects on the rate of coronary blood flow.
