Objective To investigate the relationship between peripheral inflammatory cytokines and anxiety symptoms in patients with the first?episode generalized anxiety disorder. Methods 48 patients diagnosed with the first?episode generalized anxiety disorder according to ICD?10 criteria and 48 healthy sub?jects were recruited. Peripheral levels of IL?1, IL?2, IL?4, IL?5, IL?6, IL?8, IL?10, IL?12p70, GM?CSF and IFN?γ of both groups were evaluated by enzyme?linked immunosorbent assay ( ELISA) ,and CRP was evalua?ted by immunoturbidimetric method. Generalized Anxiety Disorder Scale( GAD?7) and State?Trait Anxiety Inventory ( STAI ) were used to assess the levels of overall anxiety, state anxiety and trait anxiety. Results The levels of CRP ( ( 1. 19 ± 0. 80 ) mg/L vs ( 0. 68 ± 0. 70 ) mg/L, t=3. 31 ) , IL?1α( ( 70. 34 ± 3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50),IL?2((7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85), IL?4((102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29),IL?6((12.55±2.37)pg/ml vs (2.71±1.35) pg/ml, t=14.79),IL?8((44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10),IL?12((18.16±24.17) pg/ml vs (10.82±4.72)pg/ml, t=2.06),IFN?γ((23.32±15.52)pg/ml vs (16.48±6.80)pg/ml, t=2.79), GM?CSF((19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80) in patients with the first?episode general?ized anxiety disorder were significantly higher than normal controls(P<0.05) . Both SAI and TAI had signifi? cantly positive correlation with the levels of IL?1α, IL?2, IL?6, IL?8, IL?12, IFN?γ and GM?CSF ( r=0.24?0.76, P<0.05) . Conclusion The levels of some peripheral inflammatory cytokines in patients with the first?episode generalized anxiety disorder are significantly increased,and they have positive correlation with gener?al anxiety,state anxiety and trait anxiety,which may suggest some immune system defects in the patients.

Objective To investigate the efficiency of European System for Cardiac Operative Risk Evaluation(EuroSCORE)in predicting in-hospital mortality for the patients after percutaneous coronary intervention(PCI). Methods Retrospective analysis was conducted on the patients who had undergone PCI in our hospital since year 2005 to 2007. We used both cumulative EuroSCORE score and logistic EuroSCORE to predict the in-hospital morality and to analyze the correlation between the predicted mortality and the actual mortality. Results According to the additive EuroSCORE, we divided the patients into three groups, the additive EuroSCORE 0-2 were divided into low-risk group,3-5 were divided into mid-risk group and ≥6 into high-risk group.The actual in-hospital mortality rates were 0%, 0.47% and 6.09% respectively. The EuroSCORE model demonstrated an overall relation between the EuroSCORE ranking and the incidence of in-hospital mortality(P<0.001). Results from the multivariable logistic regression analysis showed that the EuroSCORE was an independent in-hospital mortality predictor(P<0.01). Conclusion The EuroSCORE risk model and the in-hospital mortality were significantly correlated, indicating that the model was a promising method for predicting the in-hospital mortality of PCI patients.

This study was aimed to construct mouse Fas-targeting si RNA-expressing recombinant retroviral vector in order to explore the therapeutic potential of Fas inhibition by siRNA in the treatment of aplastic anemia and to provide a basia for extensive development of RNA interference techninque. The U6(+) 27 promoter cassette and siFas sequence were obtained by PCR method. The U6-siFas fragment was cloned into the multiple restriction site of pLXSN-EGFP and directly downstream of EGFP gene. The resultant retroviral vector pLXSN/EGFP-siFas was packaged using PA317 cell line and tittered using NIH3T3 cell line. P815 cells were infected by the retroviral vector. EGFP expression in P815 was observed under fluorescent microscope and Fas inhibition effect was detected by immunohistochemistry. The results indicated that successfully constructed retrovirus vector pLXSN/EGFP-siFas was could not only deliver siRNA into mammalian cells efficiently and inhibit Fas expression in P815 cells, but also could express EGFP as marker and neomycine resistance gene to allow antibiotic selection. It is concluded that the successful construction of this retroviral vector would greatly facilitate the application of RNA interference and lay the foundation for therapeutic study of Fas inhibition in the treatment of aplastic anemia.

Based upon the underlying mechanism and pathological evidence of tissue injury of antibody-mediated rejection (AMR) , four etiological and symptomatic therapies were proposed for managing AMR, including etiological treatment of AMR including antibody-targeting, B cell or plasma cell-targeting therapies; strategies for preventing antibody-mediated endothelial damage: an inhibition of complement/antibody dependent cell-mediated pathways; anticoagulant & thrombolytic therapies for thrombotic microangiopathy secondary to endothelial damage ; anti-inflammatory therapies for acute/chronic vascular inflammation secondary to endothelial damage. Etiological treatment is essential for preventing and treating AMR while symptomatic measures, such as anticoagulant, thrombolytic and antiinflammatory therapies, are stressed. Finally the authors devised therapeutic strategies for AMR in 4 different patient groups of non-sensitized allograft recipients, sensitized allograft recipients, individuals with active AMR and those with chronic active AMR.
