This paper introduced the community service of industrial injury insurance in 3 years in a community in Zhuzhou, Hunan, and the problems and difficulties of the community service. 4 kinds of advice were suggested to improve the community service.

Objective To investigate the effects of 16-channel dedicated craniocerebral coil on brain magnetic resonance imaging(MRI)image quality in infants aged 0-6 months.Methods Thirty-two infants aged 0-6 months receiving craniocerebral MRI examination with 16-channel dedicated craniocerebral coil were enrolled as observation group,while 32 infant aged 0-6 months receiving craniocerebral MRI examination with conventional head and neck combined coil in the same period were enrolled as control group.The scanning sequences included transverse T1 weighted imaging(T1WI),T2 weighted imaging(T2WI),T2 fluid-attenuated inversion recovery(FLAIR)and diffusion-weighted imaging(DWI)sequences.The scanned images were evaluated subjectively and objectively.Results In the subjective evaluation,T1WI,T2WI and FLAIR sequences scored higher than 4,and DWI sequence scored higher than 3.There were high consistency between two raters for T1WI,T2WI and FLAIR sequences(Kappa value=0.717,0.652,and 0.784,respectively;P<0.05),and moderate consistency for DWI sequence(Kappa value=0.321;P<0.05).In the objective evaluation,the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of each sequence in the dedicated coil group were highly consistent in the left and right lobes of the brain,and the differences in the SNR and CNR between the left and right lobes of the brain were trivial(P>0.05).The SNR and CNR of each sequence in the dedicated coil group increased as compared with the conventional coil group,and the differences in the SNR and CNR of T1WI sequence and the SNR of DWI sequence were statistically significant(P<0.05).Conclusion The brain images of infants aged 0-6 months obtained with a dedicated craniocerebral coil can better meet the clinical needs,and the image quality of the dedicated coil group is superior to that of the conventional coil group in both subjective and objective evaluations.
