Chronic cough can occur in children of all ages, and the incidence rate and consultation rate increase each year.Clarifying the cause of chronic cough is the key to treatment.At present, there are no convenient, operable and unified standards for etiological analysis of chronic cough in the world.Therefore, the etiological analysis of chronic cough has always been a hot topic in clinical research.With the development of diagnosis and treatment technology, the role of pulmonary function and exhaled nitric oxide in the diagnosis of chronic cough has attracted attention.This article reviews the application value of pulmonary function combined with exhaled nitric oxide in etiology analysis of chronic cough in children, to provide reference for etiology analysis of chronic cough in children.

Novel coronavirus (2019-nCoV) is the pathogen of COVID-19. Some severe cases may suffer from respiratory failure or even death, which poses a great challenge to global public health. 2019-nCoV proteins not only participate in virus proliferation, but also play an important role in antagonizing host innate immune response, especially interferon response. In this paper, 2019-nCoV proteins involved in regulating host interferon response and the complex interaction between 2019-nCoV and interferons were summarized, aiming to provide a theoretical reference for the prevention and control of COVID-19.

A total of 118 patients with type 2 diabetes mellitus were divided into acarbose treatment group ( A group,n =58 ) and no acarbose treatment group ( B group,n =60),and 57 healthy subjects were used as control group (C group).The quantification of fecal bifidobacteria and enterococcus faecalis in these subjects was made by realtime PCR.The results showed that fecal bifidobacteria contents in A and B groups were lower and enterococcus faecalis contents were higher compared with C group.After four weeks of intervention,fecal bifidobacteria contents in A and B groups increased ( P＜0.01 ),especially in A group,while enterococcus faecalis contents decreased ( P＜0.05 )compared with the baseline.Univariate correlation analysis showed that bifidobacteria content was negatively associated with lipopolysaccharides(LPS),advanced glycation index,high sensitive C reactive protein ( hs-CRP),and body mass index ( BMI ) at baseline ( P＜0.05 or P＜0.01 ).The enterococcus faecalis content was positively associated with levels of monocyte chemoattractant protein-1,LPS,tumor necrosis factor-α,hs-CRP,plasminogen activator inhibitor-1,BMI,and HbA1c (P ＜0.01 ).After four weeks of intervention,the above associations disappeared.Stepwise multivariate regression showed that basal BMI,HbA1c,and age contributed to the increase in the number of enterococcus faecalis,and BMI negatively contributed to the decrease in number of bifidobacteria.

ObjectiveInvestigate the value and feasibility of image registration with reverse rotation in lateral cerebral DSA.Methods ( 1 ) Experimental study:the target images were subtracted directly,and subtracted again after reverse rotation.Software of registration and subtraction with reverse rotation edited by the author utilizing Visual Basic.The function of the automatic angle detection by the software were evaluated to see whether it detected the angle of line.The subtraction function of DSA by the software was evaluated.(2) Clinical retrospective study:the untreated mask and target inages of 15 patients with motion along vertical axis during lateral cerebral DSA were uploaded to the software.The target images were processed with and without the software to get two sets of images.( 3 ) Evaluation:four experienced radiologists read and compared the two sets of the images,and graded their findings.Results ( 1 ) The automatic detection by the software suggested that the target images should be rotated counterclockwise 1.3°. The subtraction result of the software was satisfactory.(2)In the 15 sets of images,there were only three sets of images deemed optimal after traditional subtraction.After reverse rotation,artifacts were significantly reduced and the image sharper. There were ten cases with significant artifacts after traditional subtraction,and those images were sharper and showed more peripheral vessels after reverse rotation. The traditional subtraction images of two sets could not be interpreted,the reverse rotation registration images reached the diagnostic quality.(3)Subjective evaluation: there were more information and less noise and distortion in the registration images with reverse rotation than in the traditional subtraction. But the image resolution decreased slightly after reverse rotation registration.ConclusionThe registration of digital angiography with reverse rotation can improve the image quality in lateral cerebral DSA.

Objective To establish a real-time fluorescence quantitative PCR method for detection of the different expression level of FPGS in methotrexate enantiomer-resistant A549 cell lines,and observe FPGS mRNA expression in patients with leukemia.Methods A real-time fluorescence quantitative PCR method for detection FPGS mRNA was established using SYBR Green Ⅰ as fluorescence and β-actin as reference.The method was evaluated by Ct,correlation coefficient,slope,repeatability curve,melting curve and amplification efficiency curve.The expression levels of FPGS gene in methotrexate enantiomer-resistant A549 cell lines and methotrexate resistant leukemia cells in bone marrow were detected by the method.Results The standard curves had a high linear relationship between cycle threshold and template concentration.The correlation coefficients of FPGS and β-actin were 0.996 8 and 0.998 7,and the slopes were -3.595 and -3.740,respectively.The inter-coefficient of variation was from 1.27% to 2.95%.The intra-coefficient of variation was 3.82%.The method was characterized with specific melting curve and similar amplification efficiency(slope was 0.021 7).The relative contents of FPGS mRNA were(3.51 ±0.66),(0.16 ±0.01) and(1.00 ±0.31) in L-(+)-MTX/A549 cells(L),D-(-)-MTX/A549 cells(D)and A549 parent cells,and there was statistically difference among the three groups(F = 64.45 ,P＜ 0.01)Statistical difference was observed between L and D(q =9.29,P＜0.01).After treated with MTX,the expression level of FPGS mRNA was(0.35 ± 0.04) in methotrexate resistant leukemia patients,compared with(1.00 ± 0.44) before treatment.Statistical difference was observed(t = 8.83 ,P＜ 0.01).Conclusions The real-time fluorescence quantitative PCR is suitable for the quantification of FPGS.The expression levels of FPGS in methotrexate resistant leukemia cells in bone marrow and drug resistant cells are different.Two enantiomer forms of methotrexate may play different roles in drug resistance mechanisms.

Objective To investigate the diagnosis and treatment in patients with acute myocardial infarction (AMI) and complicated left ventricular wall rupture (LVWR). Methods A retrospective analysis was made on the clinical features, diagnosis and successful treatment in three AMI patients with LVWR from December 2015 to April 2016. Results Three cases were included in this study. Case 1, the mesh like cardiac rupture after AMI was diagnosed by ultrasonic Doppler. Emergency revascularization was performed due to the combined cardiac shock, and the infarct related artery was opened. The vasoactive drugs were used after revascularization to reduce ventricular pressure load and volume load in the haemodynamic monitoring, and anticoagulation, antiplatelet agents were less used or discontinued to promote local thrombus healing of ventricular rupture. Case 2 was a recurrent myocardial infarction patient. LVWR was diagnosed by ultrasonic Doppler one day after emergency operation. The ruptured ventricular wall was encapsulated by thrombus. The drug therapy was effective in hemodynamic monitoring. LVWR was further confirmed by cardiac CT after clinical stabilization. Case 3 was diagnosed LVWR by ultrasonic Doppler four days after AMI. Because the ruptured ventricular wall was limited by incompletely organized thrombus, and the haemodynamic condition was stable, selective surgical repair of rupture after coronary angiography was performed. Conclusion The effective drug therapy combined with percutaneous coronary intervention and surgical repair can reduce the risk of death in patients with LVWR after AMI.
