Objective To explore the role of NT-proBNP in the differentiation of acute pulmonary embolism (APE) from congestive heart failure (CHF) in patients with acute dyspnea.Methods Consecutive 260 patients aged ≥ 60 years complaining of acute dyspnea were collected between June 2010 and October 2015.The patients were divided into two groups of APE and CHF according to their diagnosis standards.The levels of NT-proBNP between the two groups were compared using t test,and receiver operating characteristic curve (ROC curve) was made to show the value of NT-proBNP in differentiation of APE from CHF.Results Patients in APE group had significantly lower median levels of NT-proBNP as compared with patients in CHF group [(2 478.8±1 473.9)ng/L vs.(5 955.4±3 180.1)ng/L,t =-12.020,P < 0.01].The ROC curve of APE existence against serum levels of NT-proBNP showed an optimal cut-point of NT-proBNP of 1 518 ng/L,with specificity up to 98.8%,and the area under the ROC curve for NT-proBNP was 0.877.Conclusions NT-proBNP as a simple and bedside approach to identify APE versus CHF patients with acute dyspnea can help clinicians identify APE early and reduce the rates of misdiagnosis and missed diagnosis of APE.But the confirmative diagnosis of APE is still based on spiral CT angiography.

Objective: To compare blood levels of NT-proBNP and uric acid (UA) in patients with pulmonary thromboembolism (PTE) and chronic heart failure (CHF). Methods: A prospective research was conducted in 288 acute dyspnea patients treated in our hospital from 2010-06 to 2015-05. The patients were divided into 2 groups based on clinical diagnosis: PTE group,n=107 and CHF group, n=181. Blood levels of NT-proBNP and UA were examined in all patients, statistical analysis was performed by SPSS 17.0 software, independent samplet test or variance analysis were used to make comparison between 2 groups. Results: There were more male patients as 64/107 (59.8%) in PTE group and 103/181 (56.9%) in CHF group. Compared with CHF group, PTE group had the lower blood levels of NT-proBNP (2421.7±1678.1) pg/ml vs (6964.3±3873.1) pg/ml and UA (340.6±121.3) μmol/L vs (492.1±166.2) μmol/L, allP<0.01. Conclusion: In our research, blood levels of NT-proBNP and UA were lower in PTE patients than CHF patients; with general background, such phenomenon might be helpful to distinguish PTE and CHF in acute dyspnea patients in clinical practice.

Currently,there are a lot of targets for the treatment of HBV infection,both for the host,and for the virus itself.However,existed clinical drugs can only control HBV infection,and can not remove the HBV,especially cccDNA.Therefore,the chronic persistent infection caused by HBV related diseases is still seriously threat to human health.People are still impatient for the development of new effective anti-HBV drugs.In this paper,we review the recent research of the anti-hepatitis B virus based on the host as the target.

Objective To learn the psychological needs of the hospital staff in terms of their life,medical care and psychological health.Methods 2910 hospital staff were interviewed with questionnaires and the outcomes analyzed with x2 test and descriptive analysis.Results 96.9%of the surveyed found themselves in need of psychological counseling; considerable consulting needs of the staff; most of them turn to friends to complain instead of their leaders.Conclusion The psychological counseling should be enhanced to build effective communication channels and ease stress of the staff.

In order to clone lvgA gene (Legionella virulence gene) of Legionella pneumophila and detect its expression in prokaryotic cell, we amplified the lvgA gene from the total cell DNA of Legionella pneumophila with PCR,and then inserted it into the coloning vector pUC18. The recombinant plasmid pUlvgA was obtained. After the recombinant plasmid pUlvgA was identified with restriction enzyme analysis, polymerase chain reaction and nucleotide sequencing analysis, the lvgA gene was subcloned into the prokaryotic expression vector pGEX-4T-1. The prokaryotic expression recombinant plasmid pGlvgA was constructed. After IPTG induction, the E. coli JM109 containing the recombinant plasmid pGlvgA expressed fusion protein. The expression of lvgA was subsequently detected by SDS-polyacrylamine gel electrophoresis and Western-blot analysis. The results indicated that the lvgA gene of 627 bp long was amplified, the recombinant plasmids pUlvgA and pGlvgA were constructed successfully, and the GST-LvgA fusion protein of approximately 36 KDa in size was expressed in prokaryotic cell efficiently as expected.
