Objective Dickkopf-1 (DKK-1) is an antagonist of the Wnt signaling pathway of bone formation and it is the target gene of TNF.When DKK-1 is inhibited,osteoprotegerin (OPG) would increase,OPG can antagonize bone erosion caused by receptor activator of NF-κB ligand (RANKL).Detection the levelsof serum DKK-1,OPG,RANKL and TNF-α of patients with AS before and after applying TNF-α antagonist,the effects of anti-TNF-α treatment on signaling pathway of bone formation was explored.Methods Medical records and serum samples of 43 AS patients receiving TNF-α receptor-Ⅱ IgG Fc fusion protein for 12 weeks were collected and the levels of serum DKK-1,OPG,RANKL and TNF-α were detected by enzyme-linked immunosorbent assay.Paired t-test and Person's correlation analysis were used for data analysis.Results Disease activity indexes in AS patients with anti-TNF-α treatment,including VAS score,time of morning stiffness,BASDAI,BASFI,ESR and CRP,which were [(2.7±2.0) cm,(7±4) min,1.1±1.1,0.8±1.2,(10±9) mm/1 h and (16±26) mg/L] respectively,were reduced when compared with those before treatment,[(7.6±1.9) cm,(46±33) min,6.0±1.3,4.4±2.0,(39±29) mm/1 h and (76±43) mg/L] respectively,and the differences were statistically significant (P＜0.05).Serum levels of DKK-1,(3.3±1.5) μg/L vs (3.2±1.3) μg/L,OPG,(144±71) pg/ml vs (136±62) pg/ml,and RANKL,(71±37) pg/ml vs (68±30) pg/ml,were not changed (t=14.043,8.031,20.166,13.521,7.679,9.563,all P＞0.05).The levels of TNF-α increased from (1.9±1.3) pg/ml to (55.0±50.6) pg/ml (t=6.951,P＜0.05).There were no relations between DKK-1 and TNF-α,RANKUOPG,patient VAS,duration of morning stiffness,BASDAI,BASFI,ESR and CRP,allP＞0.05.Conclusion Clinical indicators are improved significantly by anti-TNF-α therapy; however,it should not be withdrawal suddenly.There is no relationship between serum levels of DKK-1 and level of inflammation in AS patients.

ObjectiveTo investigate the status medicine taking in rural schizophrenic patients.MethodsThe families of 217 schizophrenic patients in a town of Shaoxing rural area were investigated with self-made questionnaire.Results and Conclusion125 cases routinely took medicine(57.6%). The main reason caused patients to resist taking medicine was absence of family or family's care. The medicine were obtained from hospital, drugstore, free drugs from mental preventing organization, mail-order, half or more of them were free. Only 53.46% of the objects would like to receive free drugs. The most of the others want to give up. The objects suggested mental preventing organization to provide more kinds and costly free drugs, simplify procedures of obtaining drugs, permit to receive more drugs at a time and be more kindly.

0.05).Conclusions Neither the new nor old SIRS diagnostic criteria had a high conforning rate with neonatal critical illnesses;There was no significant difference between them in each clinical item.It shows that the new SIRS diagnostic criteria is not superior to the old one,therefore we should improve the neonatal SIRS diagnostic criteria in the future.

AIM:Cytochrome P450 epoxygenase 2J2 and epoxyeicosatrienoic acids ( EETs) are known to protect against cardiac hypertrophy and heart failure, which involve activation of 5′-AMP-activated protein kinase ( AMPK) and Akt.Although the functional roles of AMPK and Akt are well established , the significance of crosstalk between them in the development of cardiac hypertrophy and anti -hy-pertrophy of CYP2J2 and EETs remains unclear .Here, we investigated whether CYP 2J2 and its metabolites EETs protected against cardiac hypertrophy by activating AMPKα2 and Akt1.Moreover, we tested whether EETs enhanced crosstalk between AMPKα2 and phosphorylated Akt1 ( p-Akt1), and stimulated the nuclear translocation of p-Akt1, to exert their anti-hypertrophic effects. METHODS:The recombinant rAAV9 vector was coupled to CYP2J2 and the rAAV9-CYP2J2 construct was injected into the caudal vein of AMPKα2-/-and littermate control mice .AMPKα2 -/-and littermate control mice that overexpressed CYP 2J2 in heart were treated with angiotensin II (Ang II) for 2 weeks.Hemodynamic and cardiac functions were also evaluated after 14 days of infusion with Ang II or saline.RESULTS:Interestingly, the overexpression of CYP2J2 suppressed cardiac hypertrophy , including decreased heart size, cross sectional area of cardiomyocytes , markers of cardiac hypertrophy [ brain natriuretic peptide ( BNP) ,β-myosin heavy chain (β-MHC) and skeletal muscle α-actin (ACTA1)] and increased levels of atrial natriuretic peptide (ANP) in the heart tissue and plasma of wild-type mice but not AMPKα2 -/-mice.Measurement of left ventricular ejection fraction and fractional shortening showed that CYP2J2 overexpression prevented Ang II-induced ventricular systolic dysfunction in mice .Moreover, an Ang II-induced reduction in cardiac function, demonstrated by decreased dp/dtmax and dp/dtmin, was prevented by overexpression of CYP2J2.Mechanistically, the CYP2J2 metabolites 11,12-EET activated AMPKα2 to induce the nuclear translocation of p-Akt1, which increased production of ANP and thereby inhibited the development of cardiac hypertrophy .Furthermore , by co-immunoprecipitation analysis , we found that full-length Akt1 and an Akt1 fragment containing amino acids 150-408, which constitute the protein kinase domain , but not other frag-ments of Akt1, bind to the AMPKγ1 subunit.AMPKα2β2γ1 and p-Akt1 interact through the direct binding of the AMPKγ1 subunit to the Akt1 protein kinase domain.This interaction was enhanced by 11,12-EET.CONCLUSION:Our studies reveal a novel mechanism in which CYP2J2 and EETs enhanced Akt1 nuclear translocation through interaction with AMPKα2β2γ1 and protect against cardiac hy-pertrophy and suggest that overexpression of CYP 2J2 might have clinical potential to suppress cardiac hypertrophy and heart failure .

Objective This study has explored the role of antibody against annexin A2 in patients with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). Methods Using purified recombinant annexin A2, IgG anti-annexin A2 antibody was measured by ELISA in 101 APS patients, 41 SLE patients with thrombosis, 124 SLE patients without thrombosis and 120 healthy controls.

BACKGROUND:Absorbable bio-glass injection composed by bio-glass and calcium phosphate bone cement can be tightly combined with bone tissue by a strong chemical bond to improve the stability of the bone-implant interface.
OBJECTIVE:To investigate the effect of absorbable bio-glass injection to support the vertebral body of osteoporosis mice and its mechanism of osteogenic induction.
METHODS:Osteoporosis models were prepared in 30 female Sprague-Dawley rats undergoing bilateral ovariectomy. After modeling, model rats were randomly divided into three groups, and given polymethylmethacrylate, injectable calcium phosphate bone cement and absorbable bio-glass injection into L3-5 vertebral bone defects, respectively. L3-5 segments were removed at 12 weeks after implantation to detect the biomechanical and degradation properties, levels of calcium and phosphate, alkaline phosphatase activity, bone mineral density, levels of bone morphogenetic protein 2 and transforming growth factor β, as wel as histological observation.
RESULTS AND CONCLUSION: In the absorbable bio-glass injection group, the degradation properties, compressive strength, surface hydroxyapatite deposition amount and bone mineral density were significantly higher than those in the other two groups(P< 0.05); trabecular bone relative volume, thickness and number were significant higher than those in the other two groups (P < 0.05); serum levels of calcium, alkaline phosphatase, bone morphogenetic protein 2 and transforming growth factor β were significantly higher than those in the other two groups(P < 0.05); but the level of serum phosphate was lower than that in the other two groups(P < 0.05). These results show that the absorbable bio-glass injection can enhance the support for the osteoporotic vertebral body and induce osteogenesis, probably by increasing bone morphogenetic protein 2 and transforming growth factor β levels.
