Objective To investigate the relationship between brain natriuretic peptide ( BNP)/ N-terminal pro-brain natriuretic peptide ( NT-proBNP) and New York Heart Association ( NYHA) classification, left ventricular structure and function, and explore the value of BNP/ NT-proBNP in the diagnosis of heart failure in the elderly. Methods Fifty-five elder patients with heart failure were selected (NYHA II, n = 15; NYHA III, n = 25; NYHA IV, n = 15) (heart failure group), and another 16 elder people with NYHA I were served as control group. The plasma mass concentrations of NT-proBNP and BNP were detected by electrochemiluminescence immunoassay and immunofluorescence method, respectively, and the structure and function of left ventricle were examined by echocardiography. Results The levels of plasma BNP and NT-proBNP increased with NYHA grades, were negatively correlated with LVEF (P <0.001), and were positively correlated with LVST, LVEDD, LAD and LVMI( P < 0.05). The area under the curve of BNP in diagnosis of heat failure was 0. 879 (P < 0.001), and that of NT-proBNP was 0.914(P < 0.001). Conclusion Both plasma BNP and NT-proBNP can be used to evaluate the heart function of patients with heart failure, and are useful tools for diagnosis of HF in the elderly.

Objective To assess the diagnostic value of coronary CTA (CCTA) combined myocardial CT perfusion imaging (CTP) in coronary artery disease (CAD) with Meta-analysis.Methods Chinese and English literatures evaluating CCTA combined CTP in diagnosis of CAD in PubMed,Wed of Science,Cochrane Library,China National Knowledge Infrastructure (CNKI) and Wanfang Periodical Database from inception to December 2016 were searched.The extraction was conducted according to the criteria for diagnostic recommended by Cochrane Method Group.The quality of included studies was assessed with quality assessment of diagnostic accuracy studies-2 instrument.The statistical analysis was performed by Meta-disc 1.4 software,the diagnosis efficacy was calculated and the symmetric receiver operating characteristic curves (SROC) was drawn to obtain the area under curve (AUC).Results Five studies involving a total of 611 vessels were included.The pooled sensitivity (SEN),specificity (SPE),diagnostic odds ratio (DOR),positive likelihood ratio (PLR),negative likelihood ratio (NLR) were 0.96 (95%CI [0.92,0.98]),0.91 (95%CI [0.88,0.94],206.14 (95%CI [100,424.94]),9.33 (95%CI [5.57,15.61]),0.06 (95%CI [0.03,0.13]),respectively.The AUC of SROC was 0.977.Conclusion CCTA combined CTP has significant value in diagnosis of CAD.

Objective To explore the predictive values of the levels of blood lipids ,liver function and estrogen for the fetal dis‐tress in intrahepatic cholestasis of pregnancy (ICP) patients .Methods The indicators of blood lipids ,liver function and estrogen of mild IPC group ,severe ICP group and control group were detected respectively ,and the results were analyzed .Results The levels of triglycerides ,total cholesterol and low‐density lipoprotein were positively related to estradiol levels .Multivariate logistic regres‐sion analysis showed that cholyglycine (OR=8 .24 ,P=0 .01) and estradiol(OR=4 .46 ,P=0 .02) were significant for prediction of fetal distress in ICP patients .Conclusion Estradiol and cholyglycine levels may be better indicators for the prediction of fetal dis‐tress in ICP patients .

The specific fragment of Pneumococcal surface protein A(PspA)and Pneumococcal Surface Adhesin A(PsaA)gene was amplified by PCR from Streptococcus pneumonia 5 and Streptococcus pneumonia 19.The amplified fragnent of PspA and PsaA gene was ligated into pET-27b(+)vector and transformed into BL 21 E.coli for expression and obtain the expressive production of PspA and PsaA.Induced by IPTG,the expression level was as high as 75 % of the total disolube protein.The result showed that the recombinant plasmid could express a specific 75 kDa and 37 kDa fusion protein in E.coli BL 21,which showed the good immunogenicity and a broadly cross reactivity with the other serotypes.

Objective To explore the urban population hyperlipidemia and chronic kidney disease relationship by epidemiological studies.Methods 800 health examiners were randomly investigation.To determine these blood pressure,height,weight;to determine these urinary albumin and creatinine in urine,serum creatinine,serum total cholesterol,triglyceride,high-density lipoprotein cholesterol.To calculate glomerular filtration rate and urinary albu- min and creatinine ratio according to serum creatinine.Diagnastic criteria of CKD was eGFR30mg/g and lasted three months or more.Results 238 patients with high blood lipids was found,the overall prevalence rate was 29.75 %,patients with high blood lipids compared with the normal popula- tion.the incidence of renal injury rates were respectively 15.13 % and 9.07 %.Kidney damage rates were respective- ly 19.69% and 9.91% in the hypercholesterolemia with and without obese patients.Conclusion Hyperlipidemia has become particularly important etiology of CKD.

Objective To investigate the safe region for screw fixation in atlas lateral mass by ra- diologic measurements to conduct the operative procedure.Methods The dimensions of the pedicles were determined in 30 patients with normal atlas by CT scan and three dimensional reconstruction images of the upper cervical spine.The space available for the screw(SAS)was defined as the perpendicular distance between two lines tangential to the spinal canal and the transverse foramen,respectively.SAS was evaluated at 0?(SAS1)and 10?(SAS2)insertion angles.The location of screws in 13 cases of opera- tion were observed by CT scan images measurements of the cervical spine.Results SASI at 0?inser- tion angle was(7.81?1.28)mm and SAS2 at 10?insertion angle was(9.69?1.23)mm,with statisti- cal difference(P<0.01).For SAS1,the distance from the midline of pedicle to the midline of posterior arch and the distance from the center of C2 inferior articular process to the midline of posterior arch showed insignificant statistical difference.However,the entry point at the posterior arch of the midline of SAS2 was located at 2.0 mm lateral to the midline of ASAI.Twenty-six pedicle screws in 13 cases were inserted correctly,without cortex breakage,or nerve and vessel injury.Conclusions There is a safe region for screw fixation in atlas lateral mass.Wider space available for the screw can be acquired when transverse angle is 10?.It is necessary to confirm the safe region by using axial CT of atlas before screw fixation.
