A total of 450 residents from three neighborhood committees of Ba'nan were selected to assess their willingness to accept paid influenza vaccine and the influencing factors.Among them,273(60.7%) were willing to accept paid influenza vaccine.Age,economic status,health,flu recognition and vaccine approval were the major influencing factors of vaccination.
2.Fabrication and properties of low-crystallinity carbonate apatite monolith bone graft
Chinese Journal of Tissue Engineering Research 2013;(34):6067-6072
BACKGROUND:As a good candidate for bioresorbable bone graft, carbonate apatite monolith can be prepared by sintering procedure;however, sintering can cause carbonate loss and result in a much lower rate of
biodegradation compared to the human bone, thereby influencing the formation of new bone.
OBJECTIVE:To fabricate low-crystal inity carbonate apatite monolith as bone graft and test its properties. METHODS:Calcium carbonate monolith prepared by carbonation of Ca(OH) 2 monolith was treated in 1 mol/L
RESULTS AND CONCLUSION:The calcium carbonate completely transformed into low-crystal inity B-type
carbonate apatite after treated for 14 days. Diametral tensile strength of the final product was (10.27±1.08) MPa, which is adequate as a reconstruction material for bone defect. The carbonate content was (4.80±0.50)%, similar to that of the nature bone. The molar Ca/P was 1.63±0.01, indicating the Ca-deficient carbonate apatite is
obtained. The present method al ows an easy fabrication of low-crystal inity B-type carbonate apatite block with adequate strength and without sintering process.
ammonium dihydrogen phosphate solution at 60 ℃ up to 14 days. Diametral tensile strength was examined for biomechanical properties;X-ray diffraction analysis, Fourier transform infrared spectroscopy, scanning electron microscope observation and chemical analyses (carbonate, calcium and phosphate content) were also performed for physical and chemical properties.
3.Clinical value of Holter monitor for clinical diagnosis and treatment of dilated cardiomyopathy
Chinese Journal of Primary Medicine and Pharmacy 2015;22(2):207-209
Objective To investigate the clinical value of Holter monitor(DCG) in the diagnosis and treatment of dilated cardiomyopathy (DCM).Methods According to NT-proBNP > 2 000pg/mL,left ventricular ejection fraction (LVEF) ≤40%,New York Heart Association (NYHA) rated Ⅲ-Ⅳ,67 patients with DCM were divided into the high risk group and nonhigh risk group.All kinds of arrhythmia patients proportion was compared between the two groups,in order to understand the risk factors of DCM and arrhythmias.Results In high risk group,18 cases had ventricular tachycardia,the incidence rate was 66.7%,which was significantly higher than that of non high risk group (2 cases,5.0%) (x2 =29.271,P < 0.01).While other arrhythmia,atrial premature beats,single premature ventricular contraction,atrial fibrillation and so on,had no statistical difference (P > 0.05).Conclusion The DCM patients with various types of arrhythmia,ventricular tachycardia in patients directly influence the severity and prognosis,Holter monitor has an irreplaceable role.

6.Ursolic acid inhibits migration and invasion of human lung cancer A549 cells by targeting miRNA-133a
Chinese Journal of Pathophysiology 2016;32(12):2239-2244
AIM:To investigate the effects of ursolic acid ( UA) on the migration and invasion of human lung cancer cell line A549, and to explore its mechanism .METHODS:The cell viability was detected by MTT assay .The ex-pression of miRNA-133a was detected in the A549 cells treated with UA by real-time PCR.The miRNA-133a mimics and inhibitor were transfected into the A 549 cells, and the transfection efficiency was analyzed by real-time PCR.The cell mi-gratory and invasive abilities were determined by wound healing and Transwell methods , respectively .RESULTS:The via-bility of the human lung cancer A549 cells was significantly inhibited by UA in a dose-dependent manner (P<0.05).IC50 of UA (24 h) for lung cancer A549 cells was 31.04 μmol/L.UA treatment significantly inhibited the migratory and inva-sive abilities of A549 cells in a concentration-dependent manner , accompanied by significantly elevation of miRNA-133a expression.The mimics and inhibitor of miRNA-133a significantly upregulated and downregulated the expression of miRNA -133a in the transfected A549 cells, respectively.In addition, the viability of the A549 cells was decreased extremely after tansfected with the miRNA-133a mimics (P<0.01), so did the results of the cell migration and invasion test .The A549 cells tansfected with the miRNA-133a inhibitor showed an opposite changes of the cell viability , migration and invasion . CONCLUSION:UA inhibited the viability , migration and invasion of lung cancer A 549 cells by elevating the expression of miRNA-133a.
10.Application of intravenous flurbiprofen axetil combined with small dose of morphine for postoperative and preemptive analgesia
Journal of Shanghai Jiaotong University(Medical Science) 2006;0(02):-
Objective To compare analgesic efficacy of intravenous postoperative and preemptive analgesia with flurbiprofen axetil combined with small dose of morphine and with morphine alone. Methods One hundred and twenty patients were randomly divided into four groups: group A,morphine 30 mg +0.9% NaCl for postoperative analgesia,n=30;group B,morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30;group C,flurbiprofen axetil 100 mg + morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30;group D,flurbiprofen axetil 100 mg before operation + morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30.The drugs in each group were diluted to 100 mL and infused by a pump at a rate of 2 mL/h with a patient-controlled analgesia(PCA)bolus of 2 mL after a loading dose of 5 mL.The visual analogue scale(VAS),demanding times for PCA and incidence of side effects were recorded during the period of postoperative 24 h. Results The VAS of group B at 3 h after operation was significantly higher than those of the other three groups(P
