Objective To investigate the change of soluble P-selectin (sPsel)and von Willebrand factor (vWF)levels after ad-mission in traumatic patients and their relation with the coagulation indexes levels,coagulation disorders and prognosis.Methods 82 cases of severe trauma in ICU of Affiliated Tongji Hospital were prospectively selected and detected plasma sPsel,VWF anti-gen,protein C,activity of coagulation factor Ⅶ and routine coagulation indexes on admission and on every day within the first week after admission.The 30 d fatality rate was recorded.Results The sPsel and vWF levels on admission in the patients with coagula-tion disorders were lower than those in the patients without coagulation disorders (P <0.05)and significantly correlated with the coagulation indexes (protein C and coagulation factor Ⅶ)levels (P <0.05).The vWF level within 3 d after admission in the death patients was significantly lower than that in the survival patients,but which on 7 d after admission in the death patients was signifi-cantly higher than that in the survival patients (P <0.05 );no significant difference in sPsel level within 1 week after admission were found between the survival patients and the death patients.Conclusion Among severe traumatic patients in ICU,the low lev-els of sPsel and VWF on admission are associated with the coagulation disorders,the significant rise of vWF level on 7 d after ad-mission is associated with the increase of the 30 d fatality rate.

Objective To explore miR-21 regulation of Smad7 in lung cancer A549 cell line as well as its impact on the proliferation of lung cancer A549 cell line. Methods miR-21 mimic and inhibitors in lung cancer A549 cell line were transfected by using Lipofectamine 2000 Reagent. After 48 h, Western blot and qRT-PCR were applied to assess the expression of protein and mRNA of Smad7 . MTT assay was used to determine the proliferation influence of the transfected lung cancer A549 cell line. Results Western blot and qRT-PCR showed that A549 cell trans-fected miR-21 mimic exhibited down-regulated Smad7 protein and mRNA expression, and A549 cell transfected miR-21 inhibitor exhibited up-regulated Smad7 protein and mRNA expression. The A549 cell proliferation activity decreased significantly after transfected miR-21 inhibitors. Conclusion miR-21 inhibitors can increase Smad7 pro-tein and mRNA expression, and suppress the proliferation activity of lung cancer A549 cell significantly.

Cognitive impairment in diabetes ( CID) is one of the complications of diabetes .The features of mild or moderate cognitive disorder and the decread abilities in memory and studying are the main symptoms of CID .But it′s mechanism is still un-known .NF-κB is the original signal activator , it can activate other signal pathway of cell dysfunction .With the influence of hyperglyce-mia and oxidative stress, the expression of NF-κB is enhanced, that leads to the changes of the expression of NOS , MMP-9, TNF-α, then, these changes lead to the apoptosis of hippocampus neuron cell .This review focuses on NF-κB in order to provide evidences in studying CID by reviewing the relationship between NF-κB and it′s relative factors of NOS, MMP-9, TNF-αand CID.

Objective To investigate the relationship between Epstein-Barr virus (EBV) DNA and EBV serology markers and evaluate the clinical application values in different diseases.Methods Plasma samples from 397 diagnosed EBV infection-associated patients and 120 health donors from May 2014 to November 2015 in Wuhan Tongji Hospital were collected.Real-time fluorescent quantitative PCR was performed to detect the levels of EBV-DNA in peripheral blood mononuclear cell and plasma.ELISA was used to detect VCA IgA,VCA IgM,VCA IgG,EA(D) IgG and EBNA IgG antibodies in plasma.The positive rate of EBV-DNA and EBV antibodies were counted in each group according to the detection threshold.Kappa statistic and Spearman sank correlation test were used to analysis the correlation and uniformity between EBV-DNA and EBV serology indicators.Results The positive rate of VCA IgG in patient and health control was 94.2% (374/397) and 93.3% (112/120) respectively (χ2=0.125,P=0.67);The positive rate of EBNA IgG in patient and health control was 95.4% (379/397) and 95.0% (114/120) respectively (χ2=0.045,P=0.807);but the positive rate of VCA IgM was 5.5% (22/397) and 0% (0/120) respectively (χ2=6.9,P<0.01);The positive rate of VCA IgA was 43.3% (172/397) and 9.2% (10/120) respectively (χ2=49.5,P<0.01);The positive rate of EA(D) IgG was 42.0% (167/397) and 7.5% (9/120) respectively (χ2=49,P<0.01).The positive rate of EBV-DNA was 65.5% (260/397) and 16.7% (20/120) respectively (χ2=88.5,P<0.01);The positive rate of EBV-DNA in plasma was 45.8% (182/397) and 5.0% (6/120) respectively (χ2=66.4,P<0.01).Furthermore,the uniformity and Spearman correlation analysis showed that there was no significant correlation between EBV-DNA and EBV serology indicators.The correlation analysis between PBMC EBV-DNA and VCA IgM,VCA IgA,EA(D) IgG showed the Kappa was 0.073,0.147,0.073,respectively;the correlation analysis between plasma EBV-DNA and VCA IgM,VCA IgA,EA(D) IgG showed the Kappa was 0.144,0.369,0.288,respectively.Thus,the patients were divided into different groups according to the discharge diagnosis,it was observed that the positive rates of EBV-DNA is more than 90% in extra-nodal NK/T cells lymphoma,EBV-associated hemophagocytic lymphoid tissue hyperplasia,chronic active EBV infection and infectious mononucleosis.In nasopharyngeal carcinoma patients,the positive rate of EBV antibodies (VCA IgA and EA(D) IgG) were higher than the detection of EBV-DNA.Conclusions There was no significant correlation between EBV-DNA and EBV serology markers for the same sample.The clinical application values of EBV DNA and EBV serology markers were not identical in nasopharyngeal carcinoma,extra-nodal NK/T cells lymphoma,infectious mononucleosis and EBV-associated hemophagocytic lymphoid tissue hyperplasia.
