A total of 122 patients with acute left ventricular failure from January 2011 to December 2013 at our hospital were recruited and divided randomly into control group (n =62) and observation group (n =60).Control group received conventional therapy and Bi-level positive airway pressure (Bi-PAP) was added along with conventional therapy for observation group.And 12 and 8 patients died in control and observation groups respectively within 24 h after treatment and there was no statistical difference.The BNP levels of the control group pre-treatment and at 1 h and 24 h post-treatment were (1 040 ± 315),(995 ± 245) and (570 ± 164) ng/L.The BNP levels of observation group pre-treatment and at 1 h and 24 h posttreatment were (1 080 ±209),(995 ±245) and (490 ± 138) ng/L.BNP of observation group at 1 h and 24 h post-treatment decreased significantly compared with that pre-treatment and control group (P ＜0.01).Only at 24 h post-treatment,the BNP level of control group decreased significantly compared with that pretreatment (P ＜ 0.01).

Gene ADAM10 (a disintegrin and metalloproteinase 10) is a member of ADAMs gene family. The corresponding membrane protein contains a disintegrin domain and a metalloproteinase domain. It is involved in various biological events such as cell adhesion, cell fusion, cell migration, and membrane protein shedding and proteolysis. ADAM10 protein is overexpressed in many tumors, which interacts with adhesion molecules and critical signaling molecules associated with cancer development and tumor progression, and promotes tumor invasion and metastasis. Regulating the expression of ADAM 10 can inhibit tumor invasion and metastasis , which may become a new strategy for anticancer therapy.

Objective:To examine the reliability and validity of the Chinese version of the eating beliefs questionnaire (EBQ-18) with Chinese subjects.Methods:Totally 230 university students were recruited for the preliminary survey of the EBQ-18(224 valid questionnaires were recovered). The formal EBQ-18 was set through item analysis and exploratory factor analysis.Then, 690 university students were selected to complete the formal EBQ-18 for the confirmatory factor analysis and the internal consistency analysis(674 valid questionnaires were recovered). Adult eating behavior evaluation questionnaire(AEBEQ)were selected as the criterion measurement which to examine the association between eating beliefs and eating behavior.Test-retest reliability were examined by 260 participants randomly selected after two weeks.Data analysis was conducted by using SPSS 23.0 and AMOS 22.0 software.Results:The Chinese version of the EBQ-18 with 18 items had 3 dimensions, which were negative beliefs, positive beliefs and permissive beliefs.Confirmatory factor analysis showed that the Chinese version of the EBQ-18 had good structure validity(χ 2=333.82, df=132, RMSEA=0.08, NFI=0.91, CFI=0.92, GFI=0.90, PGFI=0.66). Cronbach α coefficient and the test-retest reliability were 0.91 and 0.87 for the total scale.The internal consistency coefficients were 0.87, 0.91, 0.86, and the test-retest reliability were 0.89, 0.84, 0.90 for the 3 factors. Conclusion:It suggests that the Chinese version of EBQ-18 is a reliable and valid assessment and can be used as an effective and reliable tool for assessing eating beliefs of university students in China.

Infection is a major complication in lupus nephritis patients,and also remains a major cause of morbidity and mortality in LN.The most common infected sites are respiratory tract,skin soft tissue,urinary system,et al.Immunological abnormity,use of glucocorticoid and immunosuppressive agents,renal insufficiency and hypoproteinemia are involved in the susceptibility of LN patients' infections.A wide variety of infectious pathogens are recognized in LN and bacterial infection is the most.Virus,fungi and tubercle bacillus also can be identified.The clinical manifestations of the infections are atypical,including fever,cough,headache,twitch,abnormity of spirit and action,et al and often confused with the multiplicity clinical manifestations of SLE activity.It is necessary to carry out clinical observation and pathogeny examination for diagnosis.All patients must receive effective anti-infective therapy in time,and adjust their glucocorticoid and immunosuppressive dosage.In order to avoid infection,it is necessary to strictly control the indication and dosage of glucocorticoid and immunosuppressers.

The B-cell lymphoma gene 2 (Bcl-2) is considered as the most important inhibiting cell apoptosis control gene,and its expression is up-regulated in asthma.Drug intervention against Bcl-2 affects signal pathways,down-regulates the Bcl-2 expression,and induces programmed cell death.It may become the target of asthma treatment.This article reviews the structure characteristics of the Bcl-2,the mechanism of regulating apoptosis,and its role in asthma.

Objective:To evaluate the antimicrobial effect of ozonated water on the putative periodontopathic bacteria.Methods:Pophyromonas gingivalis (P.g)ATCC33277,Haemophilus actinomycetemcomitans (H.a)ATCC29522,Fusobacterium nucleatum (F.n)ATCC1 0957 and clinically seperated strain of P.g(C -P.g)were treated by ozonated water with ozone concentration(mg/L) of 0.03,0.06 and 0.1 2 for 30,60,90 and 1 20 s respectively.The bactericidal effect was tested by bactericidal assay.H2 O2 was used as the positive control and distilled water as the negative control.Results:The antimicrobial rate of ozonated water agaist the bacteria increased with the ozone concentration increase.There was no statistic diffrence of the effect on P.g and C -P.g(P >0.05).Linear regression analysis showed that the βvalues of the concentration factor were over 0.95,that of the time factor under 0.1 1 .Conclu-sion:The ozonated water has dose-dependent bactericidal effect on P.g,H.a and F.n.

Objective To study the features and values of ultrasound and Helical computed tomography (CT) in diagnosis of cystic renal cell carcinoma. Methods Twenty patients were preoperatively examined by B-mode ultrasound, color Doppler ultrasound and helical CT. Results All the cases were confirmed by operation and pathology,including 12 cases on the left side and 8 cases on the right side. On B-mode ultrasound images, all lesions appeared as unilocular or multilocular cyst in 5 cases, intratumoral septum in 10 cases,intratumoral nodule in 4 cases,solid-like mass in 1 case. Color blood flow was showed within tumors in 18 patients,in which 17 cases showed the arterial spectrum with a mean resistance index of 0.66. On enhanced CT scans, all the lesions appeared as the early uneven enhancement(19 cases), septal enhancement(6 cases) and mural nodular enhancement(4 cases) respectively. The accuracy of conventional ultrasound combined with color Doppler ultrasound was 85%, while the accuracy of the enhanced CT was 80%.Conclusions Conventional ultrasound combined with color Doppler ultrasound and enhanced CT plays an important role in diagnosis of cystic renal cell carcinoma.

Objective To study MR manifestations of biliary obstructive disease.Methods MR examination (Philips Gyroscan INTERA 1.0T)in 69 patients with biliary obstructive disease were performed.The conventional sequences included:T1WI/FFE,T2WI/TSE,T2WI/SPIR and contrast-enhanced at axial position,coronal B-FFE and MRCP.All images in all cases were compared with the results of operation and pathology.Results 43 cases were benign disorder,of them,42 cases were choledocholithiasis,one case was choledochal cyst.Choledocholithiasis presented as single or multiple round or ovoid with low signal.The direct sign of malignant lesions (26 cases) was the masses with slightly high signal at the obstructive part,the indirect sign of malignant lesions was obstruction or narrow of bile duct. The MR diagnostic accuracy of obstructive location was 100%, and the accuracy for evaluating the causes of obstruction was 89.9%.Conclusion MRCP combining with B-FFE and routine MRI, analysising the direct sign and indirect sign, can improve the diagnostic accuracy of obstructive jaundice.

Objective: To construct DNA vaccine against C region gene of SARS-CoV S protein, and observe the immune response induced by DNA vaccine injection and mucosal immunization. Methods: A recombinant DNA vaccine plasmid was constructed by cloning Sc gene fragment into pcDNA3. 1( - ) ,which could induce anti-SARS-CoV specific antibodies in mouse. After mice immunized with the recombinant DNA vaccine by injection and mucosal immunization, the SARS-CoV antibodies in the sera of mice were detected by ELISA,the lymphocyte phenotypes were detected by FCM,the specific antigen expressed in tissues was detected with immuno histochemical analysis. Detect spleen and MLN lymphocyte proliferation and CD8+ CTL response in vitro. Results: The titer of anti-Sc IgG was much higher in the mouse injected pcDNA3. 1-Sc than that of control group (P
