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.

In China , some ophthalmic new drug clinical trials used placebo as control .Two principles should be con-sidered in ethical review when placebo was used in these ophthalmic new drug clinical trials .Firstly, using placebo couldn't lead to irreversible or permanent vision loss .Secondly , there should be proper risk management in protocol and risk dis-closure in consent process .There are several important factors , including effects of standard treatment , risks of using pla-cebo, risk management in protocol and risk information in informed consent form , which should be used to assess the ra-tionality of placebo in ethical review .

Objective To analyze the clinical significance and features of patient s' with inconsistent antineutrophil cytoplasmic antibodies (ANCA) test results between indirect immune fluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA).Methods ANCA were detected with IIF and ELISA method jointly among 12 386 in-patients and a retrospective analysis on the proportion of clinical features and significance was made in 589 cases with inconsistent results using Microsoft Excel 2007 statistical software.Results Among the 589 patients,68 (11.5％) were diagnosed as vasculitis,in which 51 cases as ANCA-associated vasculitis,and 521(88.4％) were diagnosed as non-vasculitis including 181 connective disease and 340 non-connective diseases in which hypertension and cardiopathy were common.The common inconsistent results of ANCA were p-ANCA/ELISA (-),IIF (-)/anti-MPO (+),IIF (-)/anti-PR3 (+),IIF (-)/anti-PR3 (+) anti-MPO (+) accounted for 24.4％ (144/589),29.5％ (174/589),15.9％ (94/589),18.5％ (108/589) respectively,these accounted for 88.3％(520/589) of total inconsistency.Conclusion The spectrum of diseases and clinical characteristics varies widely and often presents with multiorgan involvement in patients with inconsistent ANCA results.These reasons make it easy to be misdiagnosed.Attention should be paid to identify and different these inconsistency.

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 study the effects of chickpea protein hydrolysate(CPH) in different doses on of antioxidant abilities in serum,liver and heart in aged mice induced by D-galactose .Method The subacute aged model mice were made by neck back subcutaneous injection of D-galactose continually.The content of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) in the serum,liver and heart of the mice were tested.Results The SOD and GSH-Px activities in aged model group were significantly decreased and MDA significantly increased compared with normal mice;CPH in different doses evidently increased the SOD and GSH-Px activities and reduced the MDA level in serum,liver and heart in mice.Conclusion CPH can obviously increase the antioxidant ability of mice and has certain anti-aging effects,especially the high dose .

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.
