Objective:To explore the optimal concentration range of super-paramagnetic iron oxide(SPIO)of transfecting cell in the molecular imaging experiments by detecting transfection cell activity. Methods:Search in Pub Med
Embase
Cochrane Library
CNKI
VIP
CBM and Wan Fang was performed to identify relevant English and Chinese language articles
respectively. Criteria for inclusion
quality evaluation and extract the data were established based on validity criteria published by the Cochrane Methods Group. STATA12.0 was used for statistical analysis. Bias test(Begg’s inspection)
heterogeneity inspection(I2
P
Q test) was used to discuss the heterogeneity of groups
calculate the fitting values and lower and upper bounds
draw the dose-response curve
and obtain the optimal concentration range. Results:Fourteen articles were included. Funnel plot was symmetrical indicating no significant publication bias. The heterogeneity inspection(I2=60.61%;P=2.675×10-9;Q =139.62)showed a significant heterogeneity. Subgroup analysis was conducted and all subjects were divided into four groups(A to D groups)according to the different materiasl;subgroup analysis showed no obvious heterogeneity among groups. The fitting values and lower and upper bounds were calculated
the dose-response curve was drew
and the optimal concentration range of each groups was obtained. Conclusion:In the molecular imaging experiments
when SPIO fitting by PEI
dextran
dextran-PLL or prepared for the probe
the optimal concentration ranges are:4 to 6 μg/m L
10 to 50 μg/m L
10 to 50 μg/m L
5 to 25 μg/m L.
