Tuina for lumbar disc herniation: A protocol for systematic review and meta analysis.

BACKGROUND: Lumbar disc herniation (LDH) is an important factor of causing leg pain and numbness. As a secondary discipline of Traditional Chinese Medicine, tuina is widely used for the treatment of LDH in China even in other nations while its clinical value is not acknowledged universally. So, we focus on this article aims to evaluate its efficacy and safety of LDH. METHODS: Electronic databases involving Cochrane Library, PubMed, Web of Science, EMBASE, China Science and Technology Journal, China National Knowledge Infrastructure, Wanfang and Chinese Biomedical Literature Database will be pertained with appropriate search strategy. And RevMan V.5.3.5 software will be conducted as the assessment tool for bias risk, data synthesis, subgroup analysis as well as meta-analyses. RESULTS: This systematic review will provide a high-quality synthesis of current evidence of tuina for LDH. CONCLUSION: This protocol will determine whether Tuina is an effective and safe treatment method for LDH.

Magnetic Sensing Properties of PVD Carbon Films Containing Vertically Aligned Crystallites.

The demands for magnetic sensors are uprising due to the rapid development of smart equipments and internet of things. Exploring magnetic sensitive materials which are easily obtainable and of low cost thereby become of great significance. Carbon film with crystallized features was recently reported with room-temperature ferro-magnetism and magnetoresistance, owing to its spin-orbital interactions at the graphene edges and temperature-depending carrier transport properties. Such phenomena indicate that the film can serve as a novel magnetic sensitive material. In this study, carbon films with vertically aligned nano-crystallites were obtained by a plasma-assisted physical vapor deposition (PVD) method. Basic test circuits were built on the films, and the sensing properties were investigated in external magnetic fields with different intensities and relative angles to the films surface. The results showed that the carbon-based sensing devices were capable to work in the temperature region of 250-400 K. The minimum field intensity and angle change to which the device can respond were 1 mT and 2°. By substrate-introduced enhancement, the maximum changing-rate of the film resistance could reach to 1100%/T. This research pointed out a practical and simple way to build magnetic sensors with PVD carbon films.
