Curcumin shows effective anti-inflammatory activities but is seldom used in clinic because of its poor solubility in water and vulnerablity to sunshine ultraviolet effect. Novel lipid vesicles have been developed as carriers for skin delivery. In this paper, lipid vesicles-propylene glycol liposomes (PGL), Ethosomes and traditional liposomes, were prepared as curcumin carriers respectively.

Objective: To investigate the diagnostic value of multislice computed tomography (MSCT) in children with congenital lobar emphysema (CLE).

Materials & Methods: Seven children with CLE diagnosed by surgery pathology had undergone thin-slice scanning of MSCT, multiplanar reconstruction and volume rendering technique. The diagnostic value of MSCT in children with CLE was evaluated.

Objective: To evaluate the diagnostic value of multi-slice CT (MSCT) reconstructions for congenital vascular rings together with tracheal stenosis.

Methods: 9 cases of children with congenital vascular ring and tracheal stenosis confirmed by surgery were collected in the study, all cases had undergone thin slice CT contrast enhancement, the MSCT data were transmitted to the workstation for multiplanar reconstruction (MPR), volume rendering technique (VRT) and VR transparency reconstruction. With the surgical results as the gold standard, the imaging characteristics of echocardiography (UCG) and MSCT were comparatively analyzed.
