최근 미디어 시대에 짧은 영상의 발전 추세가 강하게 나타났다. 이러한 추세는 단편 영상에 대해 급진적인 발전과 동시에 혁신적인 문화의 표현 방식을 통해 중국의 우수한 전통 문화의 전파 발전을 위한 새로운 기회를 가져왔다. 이러한 환경 속에서 영상 블로커 이쯔치는 같은 유형의 셀프 미디어를 업로드함으로써 인기를 짧은 시간 내에 얻을 수 있었다. 이는 개인 매체 시대에 중화 전통 문화의 재구성과 전파하는 방법을 분석하는 데 좋은 소재를 제공했다. 본 연구는 유명한 동영상 블로커인 이쯔치의 사례를 연구하여 이를 바탕으로 셀프 미디어 시대 중국 전통 문화의 재구성과 전파에 대해 논하고자 한다. 그러기 위해 셀프 미디어 시대에 전통 문화의 재구성과 전파 방식에 대한 내용 분석을 하였다. 그 결과 현재 전통 문화 전파에 존재하는 문제점을 밝히고 보다 전통 문화를 전파할 수 있는 최적화된 전략을 제시하였다.

Background: The treatment of trigeminal neuralgia remains a challenging issue. Stem cells from human exfoliated deciduous teeth (SHED) provide optimized therapy for chronic pain. This study aimed to investigate the mechanisms underlying the attenuation of trigeminal neuralgia by SHED. Methods: Trigeminal neuralgia was induced by chronic constriction injury of the infraorbital nerve. The mechanical threshold was assessed after model establishment and local SHED transplantation. Endoplasmic reticulum (ER) morphology and Caspase12 expression in trigeminal ganglion (TG) was evaluated as well. BiP expression was observed in PC12 cells induced by tunicamycin. Results: The local transplantation of SHED could relieve trigeminal neuralgia in rats. Further, transmission electron microscopy revealed swelling of the ER in rats with trigeminal neuralgia. Moreover, SHED inhibited the tunicamycin-induced up-regulated expression of BiP mRNA and protein in vitro. Additionally, SHED decreased the up-regulated expression of Caspase12 mRNA and protein in the TG of rats caused by trigeminal neuralgia after chronic constriction injury of the infraorbital nerve mode. Conclusions: This findings demonstrated that SHED could alleviate pain by relieving ER stress which provide potential basic evidence for clinical pain treatment.

Due to the complexity and difficulty in meeting the multiphase flow complexity, similarity, and multiscale characteristics, the mechanism of snow drift is so complicated that the snow deposition prediction is still inaccurate and needs to be far improved. Meanwhile, the validation of prediction methods is also limited due to a lack of field-measured data about snow deposition. To this end, a field measurement activity about snow deposition around a cube with time was carried out, and the snow accumulation process was measured under blowing snow conditions in northwest China. The maximum snow depth, snow profile, and variation in snow depth around the cube were discussed and analyzed. The measured results indicated three stages of snow accumulation around the cube. First, snow is deposited in windward, lateral and leeward regions, and then the snow depth in windward and lateral regions increases. Secondly, when the snow in the windward region reaches its maximum, the downwash flow erodes the snow against the front wall. Meanwhile, snow range and depth in lateral regions have a significant increase. Thirdly, a narrow road in the leeward region is formed with the increase in snow range and depth, which results in higher wind speed and reforming snow deposition there. The field measurement study in this paper not only furthers understanding of the snow accumulation process instead of final deposition under complex conditions but also provides an important benchmark for validating prediction methods.
