ABSTRACT
Objective:To establish a supportive and effective management mode of scientific research project application, promote the capacity building of scientific research in the hospital.Methods:Retrospective analysis was conducted on the national and provincial scientific research projects of Xinhua Hospital Affiliated to Shanghai Jiaotong University Medical School from 2010 to 2019, and the practical effect of " point to point" management mode of scientific research project application was evaluated.Results:The funding rate of Xinhua Hospital, especially national scientific research projects and provincial talents projects, was greatly improved by adoption of the multi-dimensional " point to point" management mode of scientific research project application. The number of national scientific research projects increased from 34 (26.02 million) in 2010 to 72 (51.0851 million) in 2019.The number of provincial talents projects increased from 5 (1.05 million) in 2010 to 26 (6.5 million) in 2019.Conclusions:The " point to point" management mode of scientific research project application plays an important role in promoting the overall funding rate. Enhancement of comprehensive capacity of hospital scientific research can be achieved by further improvement of this management mode, early initiation and arrangement of funding application depending on the " close partner" entity, emphasizing scientific research talents cultivation.
ABSTRACT
Objective@#To investigate serum level changes of heart-type fatty acid-binding protein(H-FABP)and S100 calcium-binding protein B(S-100B)protein in elderly patients with chronic heart failure and their clinical significance.@*Methods@#A total of 160 patients with chronic heart failure treated at our hospital were recruited, and 80 healthy individuals receiving regular check-ups were enrolled as normal controls.Serum levels of H-FABP and S-100B and cardiac function index scores were compared between patients with different cardiac function grades.Correlations of serum H-FABP and S-100B levels with N-terminal pro-B-type natrlure tiepeptide(NT-proBNP)and with cardiac function index scores in heart failure patients were analyzed.The sensitivity, specificity and accuracy of serum H-FABP, S-100B and NT-proBNP for heart failure detection were compared.@*Results@#Serum levels of H-FABP, S-100B and NT-proBNP in elderly patients with chronic heart failure were elevated with increased cardiac function grading(F=9.823, 11.573 and 13.056, P=0.013, 0.000 and 0.000), and serum levels of H-FABP, S-100B and NT-proBNP were higher in elderly patients with heart failure than in the control group(P<0.05). Serum levels of H-FABP and S-100B were positively correlated with serum NT-proBNP levels, cardiac function grading and left ventricular end-diastolic diameter(LVEDd)(r=0.527, 0.510 and 0.487, P=0.008, 0.003 and 0.002; r=0.604, 0.496 and 0.533, P=0.006, 0.005 and 0.003), and were negatively correlated with left ventricular ejection fraction(LVEF)(r=-0.536 and-0.528, P=0.005 and 0.008). The sensitivity, specificity and accuracy of serum H-FABP combined with S-100B for heart failure detection were 93.2%, 91.6% and 95.7%, respectively.@*Conclusions@#Serum levels of H-FABP and S-100B are high in elderly patients with heart failure, and they are correlated with serum NT-proBNP levels, cardiac function grading and LVEDd.H-FABP combined with S-100B has a high positive rate for heart failure detection.

ABSTRACT
Objective To investigate the effect of sertraline on the viability and the expression of tyrosine hydroxylase (TH) and phosphorylated ERK1/2 in NGF-induced rat pheochromocytoma (PC12) cells.Methods NGF-induced PC12 cells were pretreated or directly treated with different concentrations of sertraline for 24 or 48 hours and the pretreated groups were then subjected to serum withdrawal condition. Then cell viability was determined by the cell counting Kit-8 (CCK-8). The expression of Tyrosine hydroxylase (TH) and pERK1/2in NGF-induced PC12 cells was determined by immunohistochemistry and western blot respectively. Results The viability of NGF-induced PC12 was improved after administration with sertra]ine. After 24h sertraline administration, the cells activity of PC 12 cells at 20μM ( 1.32 ± 0. 11 ) , 10μM ( 1. 17 ± 0.05 ) of direct effect, and 20μM ( 1.15 ±0.11 ) of protect effect increased dramatically as compared with control group. But high dose ( 50μM )sertraline express high toxic effect to PC12 cells. The expression of TH was increased by sertraline 20 μM at both 24h(ratio of TH/β-actin = 1.27 ±0.05) and 48h(ratio of TH/β-actin = 1. 23 ±0.08) compare with control group,and the expression of pERK1/2 also increased dramatically by sertraline 20 μM at both 24h (ratio of (pERK1/2)/β-actin = 1.41±0.05) and 48h( ratio of (pERK1/2)/β-actin = 1.40 ±0.06) compare with control group(P＜0. 01, P ＜ 0. 05). Immunohistochemistry showed similar results. Conclusion These data suggest that the neuroprotective effect of sertraline may play an important role in depression therapy, and this effect might be mediated by TH and pERK1/2 up-regulation.
