To study the ability of aptamer-modified nano-gold rods and liquid carbon-targeted PLGA nanoparticles to target in vitro using compressed sensing reconstruction algorithm, and observe the phenomenon of mediating ultrasound / photoacoustic imaging. ⋯ The successfully prepared targeting nanoparticles have good targeting and specificity for breast cancer MCF-7 cells, and it has obvious effects on ultrasound / photoacoustic imaging, and has the potential to become a dual-mode ultrasound / photoacoustic targeted contrast agent. The various characteristics provide experimental basis for subsequent in vivo targeting experiments and are expected to become good target diagnostic molecular probes.

To compare efficacy of intravitreal bevacizumab augmented with Panretinal photocoagulation versus Panretinal photocoagulation alone in high risk proliferative diabetic retinopathy. ⋯ Intravitreal Bevacizumab augmented with PRP is more effective in early regression of neovessels in high risk PDR patients.
-
To evaluate marginal fit and internal adaptation of three-unit Zr frameworks fabricated from four Zr CAD/CAM milling systems. ⋯ Different CAD-CAM systems for fabrication of Zr FPD frameworks displayed a significant influence on marginal fit and internal adaptation of restorations.

This article is based on deep learning algorithms and uses MRI to study the development of congenital heart septal defects in neonatal brain tissue. ⋯ Lateral ventricle D/D 'and C/C' is more sensitive indicator which can be evaluated with the difference between the volume of congenital heart septal defects in newborn normal neonatal brain; when the D/D 'value> 0.28, C/C' value> 0.12. For the diagnosis and evaluation of congenital heart septal defect neonatal brain volume abnormalities have a certain reference value.

To document the presentation of infected non-unions of femur in pediatric and adolescent population and evaluate the outcome of segmental bone transport with the Ilizarov method. ⋯ Majority of the patients were males, aged 9-16 years. Road traffic accidents were the commonest cause of the fractures. The Ilizarov method of segmental bone transport was effective in treating the majority of infected non-unions.
