ABSTRACT
Objective To investigate the effect of topiramate in the treatment of intractable epilepsy in children. Methods 120 cases with intractable epilepsy from May 2012 to May 2017 were randomly divided into 2 groups, the control group used antiepileptic drug treatment, study group combined application of anti epileptic drugs targeted nursing application. Results The clinical effect of the treatment group was better than that of the control group (P< 0.05). The frequency of epileptic seizure in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion In the treatment of intractable epilepsy in children, the application of topiramate in the treatment of basic care is helpful to improve the effect of treatment, the effect is ideal, and should be further popularized in clinical practice.

ABSTRACT
An optical surface edge Bloch mode is an optical state evanescently bound at an edge on a finite-size three-dimensional photonic crystal; the edge is the intersection of two termination planes on the crystal. Low-loss subwavelength-scale edge modes can appear on an <010> edge of a dielectric woodpile within a complete photonic bandgap. The mode area is as small as 0.066 squared half-in-vacuum-wavelengths. The edge mode has field maxima in vacuum near the termination surface, like surface plasmon modes. This edge mode would provide new opportunities of low-loss light localization in a sub-diffraction-limit space without the use of metal.
ABSTRACT
Surface Bloch modes induced on three-dimensional dielectric photonic crystals with a complete photonic bandgap are evanescently decaying states at surfaces and have large field overlap with low-index media, resulting in narrow spectrum linewidth and simultaneously a large resonance shift due to a perturbation of the refractive index in the background media. Surface Bloch resonance states are analyzed for (001), (100), and (110) woodpile surface planes. Low-loss, high-sensitivity surface Bloch modes are also analyzed on a flat-top (001) woodpile planar surface. These analyzed surface Bloch modes are confined in a subwavelength scale and are expected to form a basis set used for optical resonance sensing.
ABSTRACT
This review article discusses fundamentals of dielectric, low-loss, optical micro-resonator sensing, including figures of merit and a variety of microcavity designs, and future perspectives in microcavity-based optical sensing. Resonance frequency and quality (Q) factor are altered as a means of detecting a small system perturbation, resulting in realization of optical sensing of a small amount of sample materials, down to even single molecules. Sensitivity, Q factor, minimum detectable index change, noises (in sensor system components and microcavity system including environments), microcavity size, and mode volume are essential parameters to be considered for optical sensing applications. Whispering gallery mode, photonic crystal, and slot-type microcavities typically provide compact, high-quality optical resonance modes for optical sensing applications. Surface Bloch modes induced on photonic crystals are shown to be a promising candidate thanks to large field overlap with a sample and ultra-high-Q resonances. Quantum optics effects based on microcavity quantum electrodynamics (QED) would provide novel single-photo-level detection of even single atoms and molecules via detection of doublet vacuum Rabi splitting peaks in strong coupling.
