随着网络科技的迅猛发展,学生可以通过视频会议、智能手机和其他电子媒体线上教学学习最先进的中医康复知识。而线上线下混合式教学模式被认为是工作学习中最重要的支持实践之一。中医康复不仅需要理论知识作为基础,更加需要掌握一些实际操作知识。传统模式下,学生跟着老师学习固定的书本知识,动手能力基本得不到培养。线上线下教学模式出现,理论知识与实践相联系,学生成为课堂的主导,提高了学习的积极性、主动性和创造性,教学效率得到了极大的提升。通过混合式教学实践及效果反映,线上线下混合式教学是比较先进且受到学生和老师欢迎的模式,同时高质量的混合式教学实践能极大的提升教学质量。

In this work, we employ the Bethe–Salpeter (B-S) equation to investigate the spectra of free diquarks and their B-S wave functions. We find that the B-S approach can be consistently applied to study the diqaurks with two heavy quarks or one heavy and one light quarks, but for two light-quark systems, the results are not reliable. There are a few free parameters in the whole scenario which can only be fixed phenomenologically. Thus, to determine them, one has to study baryons which are composed of quarks and diquarks.

Nanoporous silica with unusual interior composite cells was synthesized with synthetic block copolypeptide Phe20-b-PBLG50 as template for the first time. Anilino-methyl triethoxy silane (AMTS) was used as an intermedium to interact with block co-polypeptide Phe20-b-PBLG50 through π-π interaction between the phenyl groups of block copolypeptide and those of AMTS. Meanwhile, AMTS co-condenses together with tetraethoxylsilane (TEOS) after hy-drolysis. The structure of composite vesicles due to the self-assembly of block copolypeptide in the or-ganic solvent was immobilized and transcribed by the formation of silica. The formation of nanopores could be ascribed to the secondary structure of block co-polypeptide and small molecular amine. Our results provide a new avenue to synthesize porous oxide materials with novel interior structures templated by the copolypeptide self-assembly under ambient con-ditions.

Nerve guidance conduit （NGC） is a potential alternative to autologous nerve for peripheral nerve regeneration. A promising therapeutic strategy is to modify the nerve guidance conduit intraluminal microenvironment using physical and/or chemical guidance cues. In this study, a neurotrophic peptide-functionalized self-assembling peptide nanofiber hydrogel that could promote PC12 cell adhesion, proliferation, and neuronal differentiation in vitro was prefilled in the lumen of a hollow chitosan tube （hCST） to accelerate axonal regeneration in a rat sciatic nerve defect model. The functionalized self-assembling peptide was developed by introducing a neurotrophic peptide （RGI, RGIDKRHWNSQ） derived from brain-derived neurotrophic factor （BDNF） to the C-terminus of the self-assembling peptide RADA16-I （Ac-（RADA）4-CONH2）. Morphological, histological, electrophysiological, and functional analyses demonstrated that the RGI-functionalized, self-assembling, peptide nanofiber hydrogel RAD/RGI could produce a neurotrophic microenvironment that markedly improved axonal regeneration with enhanced re-myelination and motor functional recovery.
